GTX 780 GPU Rendering Benchmark with Octane Render

As a follow up to our article Do you need NVIDIA Maximus for GPU Rendering, we’ve prepared some benchmarks showing how the recently released GTX 780 stacks up against its big brother the GTX Titan and the Tesla K20.

The video below provides a visual performance comparison of all three cards during the interactive rendering process. These tests are derived from the standard Octane Render benchmark and the results may surprise you.

With fewer CUDA cores, the GTX 780 easily beats the Tesla K20 but predictably falls short of the GTX Titan. As we pointed out in a recent article, performance isn’t everything when choosing a GPU for rendering. If you haven’t done so yet, take a look at the article mentioned above for more information on this topic.

Be sure to check back with us next month during Siggraph as we’ll have some very exciting news and benchmarks to share with you on the GPU rendering front.

MotoCzysz Rules the Racetrack with BOXX

The Isle of Man (IOM) TT, located on the famed island in the Irish Sea, is home to the most difficult and dangerous motorcycle racetrack in the world. It is also where, for two weeks each year, the motorsport’s major players—both manufacturers and riders alike, come to prove that they belong among the motorcycling elite. Their machines snake through 37.7 miles of narrow, winding, roads punctuated with dizzying curves and lined with trees, hedgerows, homes, and fans, in a death-defying quest to exceed average speeds over 100 miles per hour. “Death-defying” is not hyperbole. In fact, throughout its history, over 230 IOM TT riders and spectators have lost their lives during the annual race. And it is here on this track, (as well as others) that MotoCzysz has chalked up numerous victories, earning the attention of the motorcycling world.


An award-winning Portland, Oregon design firm, MotoCzysz was founded in 2003 by designer Michael Czysz, a man dubbed “a latter day Leonardo DaVinci” by Cycle News Online, and “the most creative motorcycle designer working today,” by Motorcyclist magazine. From inspired engineering to bold design, Czysz reveals a passion for speed and fierce commitment to innovation that infuses all aspects of his company. For example, in 2006, MotoCzysz made the surprising transition from petrol-powered motorcycles to the new frontier of electric motorcycle racing—a move that appeared to be paying off in 2009 when the IOM played host to the first ever all-electric motorcycle road race. MotoCzysz arrived with their state-of-the art E1pc bike which was out in front when an unexpected electronic snafu sidelined the vehicle, preventing it from completing a full lap. Undaunted, the team returned with rider Mark Miller in 2010, winning the race now known as the TT Zero (“zero” meaning “zero toxic/noxious emissions”).

The following year, rather than settle for an upgrade of their victorious E1pc bike, Czysz and his design team started from scratch, creating a new machine that was 50 lbs. lighter and nearly 50percent more powerful. Heralded for amore compact, single-battery design and innovative inboard suspension configuration (inspired by Formula 1 cars) the third-generation 2011 E1pc, ridden by Michael Rutter, clocked an average speed of 99.604 mph, winning yet again. Miller came in second on a companion E1pc.

The biggest triumph yet however, arrived In 2012 when MotoCzysz’ latest edition E1pc, with Rutter on board, took first place and became the first electric motorcycle to lap the Mountain Circuit at over 100 mph, even hitting 150 mph on a famed section of the lap known as Sulby Straight. The honors didn’t stop there. MotoCzysz rider Miller also broke the coveted 100mph barrier, taking third. With three consecutive first place victories (not to mention a second and third) MotoCzysz is now the winningest American motorcycle manufacturer at the IOM. At present, the design firm is engaged in preparation for Isle of Man TT Zero 2013 and also hoping to create an aerodynamic bike capable of breaking the current world land speed record of 215.96 mph. “It’s always a big push to get there,” says senior engineer Nick Schoeps, referring to the Isle of Man TT. “As races approach, there is always more to do and of course, we want to win. Sometimes the line gets blurred between business and racing.

”MotoCzysz conquers the track not only through high performance and technology, but also with inspired design and industry-leading innovation. The engineering team is at the core of the company’s success, and in addition to their reputation for building meticulously engineered machines, they are also unique to the industry as an in-house unit that designs and fabricates most of the components used in their motorcycles and D1G1TAL DR1VE™ products. Over the years, innovative MotoCzysz designs have garnered attention from major vehicle manufacturers like Segway, who hired the firm to modernize the look and performance of their renowned personal transporter. MotoCzysz innovation has also helped to forge significant technological partnerships with companies like Dassault Systèmes SolidWorks, Bunkspeed, NVIDIA, and BOXX Technologies.

 

SIMULATION DRIVEN DESIGN 
In fact, it was NVIDIA who offered MotoCzysz an opportunity to pilot their Maximus technology used in a series of computer workstations from BOXX Technologies. 3DBOXX workstations featuring NVIDIA Maximus technology combine the visualization and interactive design capability of NVIDIA Quadro® graphics cards with the computing power of NVIDIA Tesla® GPUs into a single system. The Tesla card(s) perform photorealistic rendering or engineering simulation computation, freeing CPU resources to accomplish I/O, running the operating system, and other tasks. The Quadro GPU is dedicated to powering interactive design. Maximus also helps users reduce the need for expensive prototypes by moving their workflow to simulation-driven design—and that was just what MotoCzysz needed.

The firm’s engineers continually refine their designs in order to create the most powerful and light-weight components possible. However, as MotoCzysz began to take on more complex surfacing projects, it was becoming clear that a workstation with greater GPU capabilities was needed. The design firm’s overclocked, liquid-cooled 3DBOXX 3960 XTREME systems, state-of-the art when purchased in early 2011, were single GPU systems relying on an older generation NVIDIA Quadro card. This meant engineers couldn’t spend the time necessary to render designs at full quality. With only six full-time employees and a limited budget, MotoCzysz had to carefully balance design decisions and cost concerns—all under the added burden of a remarkably tight schedule. “With the older systems,” admits Schoeps, “we had to be pretty judicious about our resources.”

For example, MotoCzysz engineers had developed a new fairing design (the shell placed over the frame to reduce air drag, as well as protect the rider and engine) only to discover that after actually producing the part, it included surface imperfections requiring additional body fillers. Had they been able to complete a more detailed render during the design process, the engineers could have detected the imperfections and subsequently altered their design before the part went into production. This would have saved time, money, and most importantly on the racetrack—unnecessary weight.

In order to cross the finish line first, MotoCzysz needed a better solution for going from digital designs directly into production, but they also needed a budget-friendly solution that wouldn’t deplete existing computing resources. To further complicate matters, although MotoCzysz relies on SolidWorks for approximately 90% of their project work, they were also investigating other rendering and analysis tools. As it turns out, the team found what they were looking for: the rendering application was Bunkspeed and the hardware solution was BOXX.

BETTER BOXX, BETTER BIKE
In order to upgrade their workflow, Schoeps and his engineering team selected the world’s fastest single processor workstation, the 3DBOXX 4920 XTREME. Featuring a six core Intel® Core™ i7 processor overclocked to 4.75 GHz, liquid cooling, and solid state drives, XTREME provides outstanding support and application interactivity for engineering, architectural visualization, motion media, and rendering workflows. “We went to BOXX in the first place because they’re the fastest systems we could buy,” explains Schoeps, “and BOXX is the only workstation manufacturer that overclocks the CPU and still provides a three year warranty.”

Of course, the 3DBOXX 4920 XT also includes Maximus technology: a Quadro K5000 and a Tesla K20, built on NVIDIA’s fastest-ever Kepler GPU architecture. “The 4920 XTREME with NVIDIA Maximus makes sense for us is because we can create fully rendered images of a bike before we actually build it,” says Schoeps. “A major manufacturer might make several passes, create a physical clay model, and then make further refinements to the design. With our small staff and budget we need to do it all in one pass.” In addition, the benefit of real time feedback, as well as the satisfaction of knowing that their design is correct on the first pass, translates into a 20-30% increase in time savings alone.


With the earlier model workstations, Schoeps’ team was forced to shut down a number of graphics features and simplify their models in order to make the rendering workflow more manageable. But with the 4920 XT, Maximus allows them to use all the graphics features and create physically accurate renders. This enables them to see every detail and then tweak where necessary—while still in the rendering phase. “That’s a huge advantage and something we hadn’t been able to do before,” he says. Another unfortunate consequence of the simplified design versions was the difficulty of manipulating models at a lower frame rate. Now, when running SolidWorks’ Real View Graphics on the 4920 XT, MotoCzysz engineers are able to look at curvatures of a particular surface with no lag. This enables both clients and project supervisors to make design decisions earlier in the process, saving time and money. “Now the large assemblies open with a lot of SolidWorks graphics features on,” says Schoeps. “We can rotate and review with a high frame rate and no lag time.”

As for Bunkspeed Pro, still considered a relatively new tool in the MotoCzysz arsenal, the BOXX workstation is also credited for accelerating its adoption. “Bunkspeed’s performance on this system has been outstanding,” said Schoeps. “I can rotate the model and it updates the design in real time. I can see how the different design features are interacting and how light is reflecting from different angles—all in a high frame rate.” 3DBOXX 4920 XTREME also enables Schoeps to multitask, creating a motion animation in SolidWorks while Bunkspeed Pro performs raytrace renderings in the background. This also provides another benefit. “For me,” he confesses, “it also breaks up the monotony of always doing surface work.” “We went to BOXX in the first place because they’re the fastest systems we could buy,” – Nick

Most importantly however, the system allows Schoeps to concentrate on engineering. “That’s what I like most about the BOXX,” he says. “It allows me to be a lazier engineer. I don’t have to think about the number of files I have open. I’ve had as many as twenty or more parts files open along with a large assembly and there are no problems, no lag in performance. It’s nice to have the freedom to think about the design, focus on the aspect of the project I’m working on and not think about working on the machine. The machine works for you.”

The absence of lag time is just one indication of the speed and performance of the 4920 XTREME. “It really flies. Load time, boot time, a five to ten percent performance increase when opening and closing files—it’s so much faster,” Schoeps says. “I’m continually amazed at how quickly it turns on. When I used to turn on the old system, I’d go make coffee, come back, and it was ready. 4920 XTREME boots up in less than ten seconds. I had to start making coffee faster.”

In addition to the Maximus technology and overclocked Intel Core i7 processors, Schoeps credits the fast performance (and subsequent time savings) to the inclusion of solid state drives. “SSDs really require a cost benefit analysis,” he says. “You pay a few hundred dollars more for SSDs , but how do you justify the cost of hiring another engineer? It makes economic sense to spend the money on the hardware that you rely on every day.”

OVERCLOCKED
While MotoCzysz still manages to take on three to five additional projects per year, the design firm’s primary focus is still the E1pc—and winning races. So as they prepare for this year’s Isle of Man TT Zero, the improved performance throughout the design and rendering processes has enabled the engineering team to look at each aspect of their motorcycle design from a fresh perspective. “All the tools we add allow us to do more and do our jobs better,” explains Schoeps. “The reduction in time provided by the 3DBOXX workstation simply means that we have the opportunity to take more passes and that could mean saving 40 grams from the construction of a specific part or (what Schoeps considers his chief responsibility) do more to keep the rider safe. It’s a personal goal. Bikes can hit 200 miles per hour. We’ve done 170 already.”

As for the ongoing MotoCzysz/BOXX relationship, Schoeps sees a commonality between two unique American companies. “Our engineers want to make the best product possible,” he says. “They take great pride in that, and I feel like BOXX approaches their work the same way. They do a great job engineering their workstations.” And for Schoeps, the comparison doesn’t end there. Like everything MotoCzysz does, it all comes back to a need for speed. “We’re kind of an overclocked company ourselves,” he laughs. “Like BOXX, we work fast and cover a lot of ground.”

Nick Schoeps is the Lead Engineer at Motoczysz in Portland, OR. Nick’s diverse engineering background and systems-thinking approach streamlines the design process of Motoczysz products. Recent accomplishments include consecutive wins at the Isle of Man TT-Zero races, a product re-design of Segway’s i2 personal transporter, and development of the Motoczysz Digital Drive product line. Previously, Nick pioneered Fuel Cell technology at Adaptive Materials Inc. where he set world record flights for small UAVs. He holds a BSME from The University of Michigan in Ann Arbor.

Do you need NVIDIA Maximus for GPU Rendering?



In the past few years, many 3D artists have begun to take advantage of GPUs in their workflow. Renderers like V-Ray RT, iray, Octane, and others offer the ability to accelerate the rendering process by offloading the ray tracing calculations to the GPU. In addition to rendering, the GPU also plays a role in other areas of the pipeline like fluid and particle simulation. In this article, we’ll take a look at how 3D artists are using GPUs in their workflow and discuss the potential benefits of NVIDIA’s 2nd generation Maximus technology.

The Problem
Frequent disruption in creative momentum can prevent you from realizing the artistic intent of your project. An example of this disruption in the past was the familiar create-render-revise approach.

GPUs brought the promise of shortening this delay between iterations. Tasks like tweaking shader properties, lighting conditions and particle parameters could constantly be evaluated without having to generate dozens of test renders. 

Realtime visual feedback was suddenly possible. As the GPU became more widely used for this purpose, artists quickly began to demand more out of them. To take full advantage of a GPU accelerated 3D workflow today, you need a multi-GPU workstation for a few reasons. For example, the performance of these renderers and plugins often scale very nicely as you add more GPUs. 

NVIDIA refers to this concept as “speed of thought creativity” and points to their Maximus technology as the key to its success. 

Another reason to opt for a multi-GPU system is to maintain a high level of viewport interaction with your scene. The utility of an interactive GPU renderer can be diminished by sluggish viewport frame rates. In some cases this is caused by having a single GPU drive both the compute (rendering) as well as the display (viewport performance).

What is Maximus?

Many users are still confused on the benefits of configuring your workstation for Maximus. Simply put, it allows you to take full advantage of multi-GPU systems in certain situations.

The technology requires a combination of NVIDIA’s professional Quadro and Tesla cards which are enabled by their Unity driver. These cards can be cost prohibitive for some and many will likely steer away from them due to cost alone. After all, it’s no secret that the much more affordable GTX cards are quite capable at rendering.

We asked Eugene Kwak of NVIDIA to take us a little more in depth on the benefits of a Maximus workstation.

BOXX: Given the widespread use of GTX cards for rendering, what tangible performance benefits could a user expect in a Maximus configuration over a GTX configuration?

Eugene: While GTX cards certainly are excellent and offer great performance,  Maximus, which is based on the professional lineup of cards (Quadro + Tesla) offer additional confidence through certifications with ISVs.  This ensures that the hardware and software are optimized to run reliably and as fast as possible.   GTX cards do not offer this benefit. 

BOXX: If a 3D artist feels that the work they do isn’t mission critical, can you elaborate on what they might be missing if they opt for a GTX configuration instead of Maximus?

Eugene: Maximus is not just about mission critical tasks – It’s also about having the support of the application vendors to ensure that any updates to the application are fully realized in the Maximus configuration.  Additionally,  with more applications in the Media and Entertainment space supporting multi GPU applications, the benefits of Maximus will continue to grow while still maintaining a high level of reliability and support.

BOXX: Can you elaborate on the Unity driver and how it makes Maximus more efficient at assigning GPU tasks?

Eugene: The unified driver used in Maximus is quite intelligent and ensures that resources are allocated properly to make use of the powerful GPUs you have on hand.  In addition, with the latest drivers, the Maximus Configuration Utility gives you the flexibility to turn Error Correcting Code (ECC) mode on and off depending on how critical your application is.  You are also given the option to allocate more of your Quadro resources to assist in computations alongside the Tesla card.  The ability to view your GPU usage on your Maximus system is provided as well.


BOXX:
Can you identify any other benefits a user could expect when using a Maximus configuration that aren’t covered above?


Eugene: Maximus represents the future for workstations.  More and more applications require serious horse-power while being super reliable. NVIDIA Maximus is a combination of boards which are all assembled at NVIDIA to exacting specifications and standards. In addition, ISVs have taken note of the benefits of multi GPU systems and are optimizing their applications to run these configurations.  Multi-GPU systems will become a lot more commonplace in the near future.  

Take a look at the following video demonstrating V-Ray RT for Autodesk Maya on a Maximus configuration.

Why use Maximus?
NVIDIA’s stance is that each GPU task in your workflow needs to be paired with a GPU that was designed to perform that task (Quadros for visualization and Tesla for compute)
Since the Tesla is a coprocessor and designed for computation only, there is no way it can it can take a performance hit by wasting resources on visualization – a process the Unity driver optimizes with intelligent GPU job allocation.
 

NVIDIA also works with several leading software companies to certify and optimize their Quadro and Tesla cards for peak performance. Should you run into an issue on a Maximus rig, there is the added benefit of professional technical support directly from their engineers. GTX cards are not professionally supported by NVIDIA or by BOXX Technologies.



Pro cards Vs. Game cards

Since the inception of GPU rendering, artists have been using GTX cards. They are much more cost effective and relatively fast compared to Quadro and Tesla. So why not just go with a multi GTX configuration and specify though your software which cards to use for compute? The answer: it depends on what you’re trying to accomplish.
Setting CUDA devices for V-Ray RT

Your application may not allow you to specify (though most do) or you might want to multitask with more than one GPU accelerated application open.




Another reason could be that your workflow requires constant interaction and iteration of your models in your application viewport while simultaneously getting feedback from your GPU renderer (a mission critical creative workflow). If you have tried a GTX configuration and are experiencing sluggish performance, a Maximus optimized workstation could be the solution in this case.
Ultimately there are many factors that can be applied to a pros/cons discussion on “professional” cards vs. “gaming” cards. In terms of raw rendering speed, the card with the most CUDA cores will win. Currently there is a tie at the high end where the GTX Titan and the Tesla K20X both have 2688 cores. 

Cores are a big factor but certainly not the only feature you should consider.

The amount of memory on the GPU is a deciding factor for many since your entire 3D scene and all of its assets (textures, proxy files, etc.) have to fit on the GPU. The Titan is the exception among GTX cards with 6GB of memory. “Lower end” GTX cards have significantly less memory.

Other factors include the improved reliability/stability of Quadro and Tesla cards compared to GTX, whose technology is licensed by NVIDIA and built by numerous 3rd party manufacturers.
Conclusions

At BOXX, Our highest priority is building and configuring the ideal workstation for your workflow and the applications you use.

If all you need is raw GPU rendering power at low cost, then you should go with a GTX-based system.

If you deal with high poly scenes that require rapid design iteration and interaction in an environment where performance and reliability are paramount, then a Maximus configuration is likely the best choice.

BOXX Technologies is uniquely suited to build you the most reliable GPU workstations you can buy. By working with partners like NVIDIA along with our dedicated engineering and support team, you can be certain that the BOXX you buy is the optimal solution for your workflow and budget.
