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 GeForce 8800 GTS.

The HD 7870 has a 637 MHz higher core clock speed and 56 more Texture Mapping Units than the GeForce 8800 GTS. This results in the HD 7870 providing 79.7 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 637 MHz higher core clock speed and 12 more Render Output Units than the GeForce 8800 GTS. This results in the HD 7870 providing 26.5 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 three years more recently than the GeForce 8800 GTS, and so the HD 7870 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 8800 GTS when running the latest games.

The HD 7870 has 1728 MB more video memory than the GeForce 8800 GTS, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7870 also has superior memory performance overall.

The HD 7870 has 96.6 GB/sec greater memory bandwidth than the GeForce 8800 GTS, which means that the memory performance of the HD 7870 is massively better than the GeForce 8800 GTS.

The Radeon HD 7870 PCS+ Vortex II Edition has 1280 Shader Processing Units and the GeForce 8800 GTS has 96. However, the actual shader performance of the HD 7870 is 1251 and the actual shader performance of the GeForce 8800 GTS is 113. The HD 7870 having 1138 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 GeForce 8800 GTS.

The HD 7870 transistor size technology is 62 nm (nanometers) smaller than the GeForce 8800 GTS. This means that the HD 7870 is expected to run massively cooler and achieve higher clock frequencies than the GeForce 8800 GTS.

The GeForce 8800 GTS requires 143 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 400 Watts for the GeForce 8800 GTS. The HD 7870 has been recommended a PSU with 100 Watts more than the GeForce 8800 GTS. The difference is significant enough that the HD 7870 may have an adverse affect on your yearly electricity bills in comparison to the GeForce 8800 GTS.

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.
GeForce 8800 GTS is a high-end GPU based on the 90nm variant of the first-shader unified architecture.
It's based on the G80 Core and offers 96 Shader Processing Units, 24 TMUs and 20 ROPs, on a 320-bit memory interface of GDDR3. The central unit runs at 513MHz and the memory clock operates 792MHz. It will consume no more than 143 Watt.
Technically, next in series, when compared to GeForce 8800 GT, it performs worse as the amount of Shader Processing Units and TMUs was reduced and the GPU comes under-clocked, in exchange for a wider bus-width and extra video memory.
Today's modern demanding games can be played at medium (most) or high settings (some) smoothly. However, this GPU will perform poorly at 720p due to the limited video memory. DirectX 11 based games aren't supported.
