A new case study from Nvidia reveals the impact of adding a few NVidia Quadro’s to the rendering pipeline of Tigar Hare, creators of games like “Call of Duty: Black Ops” and “Project Gotham Racing”. A long-time user of V-Ray, they used the new V-Ray RT technology and Quadro Fermi GPU’s to take their renders from hours to real-time.
To compare GPU-based ray tracing, Hare benchmarked a wide range of hardware configurations, rendering the same scene using V-Ray RT 2.0 on each system.
The scene was set up to use a 3ds Max render time of two minutes. In that timeframe, a 12-core CPU processed just 100 samples — while a combination of three NVIDIA Quadro and Tesla GPUs handled a whopping 1,056 samples – a more that 10X improvement. This same GPU combination in one machine was also 3.8X faster than distributing the job across 80 CPU cores. The NVIDIA Fermi architecture incorporated into the company’s new GPUs also demonstrated a dramatic improvement over earlier GPUs, with the Quadro 5000 yielding 5.5X the speed of the older Quadro FX 5600. It also showed great multi-GPU scaling when combining three new GPU’s: nearly tripling the performance of a single Quadro GPU.
Of course, a Quadro and 2 Tesla’s isn’t cheap, but it’s an impressive statistic when (as stated above) it comes in almost 4x faster than an 80-core system.
