Testbed Configuration and Testing Methodology
We are going to test professional graphics cards in a workstation based on the today’s fastest six-core desktop processor – Intel Core i7-3970X Extreme Edition with the nominal frequency of 3.5 GHz. This platform also used an Intel X79 Express based mainboard and 16 GB of high-speed DDR3-1867 SDRAM.
Quadro K5000 on Kepler design will be competing primarily against the previous generation professional graphics card from Nvidia on Fermi design – Quadro 5000. Moreover, in order to illustrate the performance differences between the general-purpose and professional graphics accelerators, we also included one of the flagship gaming products with the same architecture as Quadro K5000.
Therefore, our complete testbed was configured as follows:
- Processor: Intel Core Core i7-3960X Extreme Edition (Sandy Bridge-E, 6 cores + HT, 3.3-3.9 GHz, 6 x 256 KB L2, 15 MB L3).
- Mainboard: ASUS Rampage IV Formula (LGA2011, Intel X79 Express).
- Memory: 4 x 4 GB, DDR3-1866 SDRAM, 9-11-9-27 (Kingston KHX1866C9D3K2/8GX).
- Graphics cards:
- Nvidia GeForce GTX 680 (2 GB/256-??? GDDR5, 1006/6008 MHz);
- Nvidia Quadro 5000 (2.5 GB/320-??? GDDR5, 513/3000 MHz);
- Nvidia Quadro K5000 (4 GB/256-??? GDDR5, 706/5400 MHz).
- Storage sub-system: Intel SSD 520 240 GB (SSDSC2CW240A3K5).
- Power supply unit: Corsair AX1200i (80 Plus Platinum, 1200 W).
- Operating system: Microsoft Windows 7 Ultimate x64.
- Intel Chipset Driver 22.214.171.1245;
- Intel Management Engine Driver 126.96.36.1998;
- Intel Rapid Storage Technology 188.8.131.520;
- NVIDIA GeForce Driver Release 310;
- NVIDIA Quadro/Tesla Driver Release 310;
- NVIDIA 3ds Max Performance Driver 13.00.04;
The tests were executed in 1920x1200 resolution with Vsync disabled. For this test session we used popular CAD and 3D modeling applications and special tests from Special Performance Evaluation Corporation (SPEC). The diagrams below show the scores in points, which means that higher score stands for better performance.
