NVIDIA Quadro 5000 (GF100/Fermi)
ATI FirePro V8800 (Cypress XT)
NVIDIA’s Quadro 5000 can be seen as the professional version of the GeForce GTX 465. The Quadro 5000 is based on the same chip than the GTX 460, the GF100 (Fermi) with 352 CUDA cores:
A Quadro 5000 is priced at around $2200.
ATI’s FirePro V8800 can be seen as the pro version of the Radeon HD 5870. Both cards are based on the Cypress XT GPU with 1600 stream processors.
A FirePro V8800 is priced at around $1500.
More details are available in Tom’s Hardware test:
Workstation Shootout: Nvidia Quadro 5000 Vs. ATI FirePro V8800.
Keep in mind that the Quadro 5000 is based on a limited version of the GF100. The flagship version is the Quadro 6000 with 448 CUDA cores.
And according to the results of the test, the Quadro 5000 dominates the FirePro V8800. But it’s not really from a hardware point of view but rather from a driver point of view. NVIDIA Quadro graphics drivers are highly optimized while this is not the case with AMD ones… Still a story of drivers with AMD.
Like Nvidia, AMD artificially hobbles its Radeon-class desktop cards through the driver, ensuring that only FirePro models will offer top performance in workstation scenarios.
