In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7870 PCS+ Vortex II Edition are massively better than the Nvidia Quadro 4000.

The HD 7870 has a 675 MHz higher core clock speed and 48 more Texture Mapping Units than the Quadro 4000. This results in the HD 7870 providing 76.8 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7870 has a 675 MHz higher core clock speed than the Quadro 4000 and the same number of Render Output Units. This results in the HD 7870 providing 21.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7870 was released over a year more recently than the Quadro 4000, and so the HD 7870 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Quadro 4000.

The Radeon HD 7870 PCS+ Vortex II Edition and the Quadro 4000 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 7870 has 70.1 GB/sec greater memory bandwidth than the Quadro 4000, which means that the memory performance of the HD 7870 is much better than the Quadro 4000.

The Radeon HD 7870 PCS+ Vortex II Edition has 1280 Shader Processing Units and the Quadro 4000 has 256. However, the actual shader performance of the HD 7870 is 1251 and the actual shader performance of the Quadro 4000 is 243. The HD 7870 having 1008 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7870 delivers a massively smoother and more efficient experience when processing graphical data than the Quadro 4000.

The HD 7870 transistor size technology is 12 nm (nanometers) smaller than the Quadro 4000. This means that the HD 7870 is expected to run slightly cooler and achieve higher clock frequencies than the Quadro 4000.

The Quadro 4000 requires 142 Watts to run but there is no entry for the HD 7870. We would recommend a PSU with at least 500 Watts for the HD 7870 and a PSU with at least 500 Watts for the Quadro 4000. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon HD 7870 PCS+ Vortex II Edition is a special edition of Radeon HD 7870.
This is one of today's most powerful editions of the reference as it features increases in both the core and memory clocks that went from 1000MHz to 1150MHz and from 1200MHz to 1250MHz.
Benchmarks indicate the performance boost is quite extreme and around 8% when compared to the reference Radeon HD 7870.
Quadro 4000 is a middle-class professional card based on the 40nm, Fermi architecture.

It's based on the Fermi GF100-100-KD GPU and thus offers 352 Shader Processing Units, 44 TMUs and 40 ROPs, on a 256-bit memory interface of fast GDDR5. The central unit runs at 450MHz and the memory clock operates at up to 702MHz. It has a L2 Cache of 384KB and a rated board TDP of 142 Watts.

Despite exhibiting similarities to GeForce GTX 460, due to being under-clocked and because Quadro 4000's drivers are only certified for professional applications only, its gaming performance is up to 10% slower than GeForce GTS 450.
