Today, NVIDIA announced its flagship Quadro graphics card called the K6000. Back in March of this year, NVIDIA launched a new like of Quadro graphics cards for workstations. Those cards replaced the Fermi-based predecessors with new models based on NVIDIA’s GK-104 “Kepler” GPUs. Notably missing from that new lineup was NVIDIA Quadro K6000, which is the successor to the Quadro 6000.
Contrary to previous rumors, the Quadro K6000 will be based on the full GK110 chip. In fact, it will be the fastest single-GPU graphics card that NVIDIA has to offer.
The Quadro K6000 features a full GK110 GPU, 12GB of GDDR5 memory on a 384-bit bus, and a 225W TDP. The full GK110-based GPU has 2,880 CUDA cores, 256 TMUs, and 48 ROPs. Unfortunately, NVIDIA has not yet revealed clockspeeds for the GPU or memory.
Thanks to the GPU not having any SMX units disabled, the NVIDIA Quadro K6000 is rated for approximately 1.4 TFLOPS of peak double precision floating point performance of and 5.2 TFLOPS of single precision floating point performance.
The chart below illustrates the differences between the new flagship Quadro K6000 with full GK110 GPU and the highest tier Tesla and consumer graphics cards which have at least one SMX unit disabled.
NVIDIA GK110-Based Graphics Cards
|Quadro K6000||Tesla K20X||GTX TITAN|
|Memory Bandwidth||288 GB/s||250 GB/s||288 GB/s|
|Single Precision FP||5.2 TFLOPS||3.95 TFLOPS||4.5 TFLOPS|
|Double Precision FP||~1.4 TFLOPS||1.31 TFLOPS||1.31 TFLOPS|
The NVIDIA GTX TITAN gaming graphics card has 2,688 CUDA cores, 224 TMUs, and 48 ROPs and is rated for peak double and single precision of 1.31 TFLOPS and 4.5 TFLOPS respectively. On the other hand, the lower-clocked Tesla K20X compute accelerator card has 2,688 CUDA cores, 224 TMUs, and 48 ROPs along with lower clockspeeds on the memory and GPU. Because of the lower clockspeeds, the K20X is rated for double and single precision floating point performance of 1.31 TFLOPS and 3.95 TFLOPS and memory bandwidth of 250GB/s versus the 288GB/s bandwidth on the TITAN and K6000.
NVIDIA® Quadro® K6000 GPU
In all, the new K6000 is an impressive card for professional users, and the GK110 chip should perform well in the workstation environment where GK104 was the only option before. NVIDIA claims that the GK110 is up to 3-times the performance of the Quadro 6000 (non K) predecessor. It is also the first Quadro GPU with 12GB of GDDR5 memory, which should lend itself well to high resolutions and artists working with highly detailed models and simulations.
Specifically, NVIDIA is aiming this graphics card at the visual computing market, which includes 3D designers, visual effects artists, 3d animation, and simulations. The company provided several examples in the press release, including using the GK110-based card to render nearly complete photorealistic vehicle models in RTT Deltagen that can run real time during design reviews.
The Quadro K6000 allows for larger and fully populated virtual sets with realistic lighting and scene detail when 3D animators and VFX artists are working with models and movie scenes in real time. Simulation work also takes advantage of the beefy double precision horsepower to support up to 3-times faster simulation run times in Terraspark's InsightEarth simulation. Users can run simulations with wider areas in less time than the previous generation Quardo cards, and is being used by oil companies to determine the best places to drill.
Pixar's Vice President of Software and R&D Guido Quaroni had the following to say regarding the K6000.
"The Kepler features are key to our next generation of real-time lighting and geometryhandling. The added memory and other features allow our artists to see much more of thefinal scene in a real-time, interactive form, which allows many more artistic iterations."
The K6000 is the final piece to the traditional NVIDIA Quadro lineup and is likely to be well recieved by workstation users that need the increased double precision performance that GK110 offers over the existing GK104 chips. Specific pricing and availability are still unknown, but the K6000 will be available from workstation providers, system integrators, and authorized distribution partners beginning this fall.
