Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 3870 X2 512MB
IntroThe GeForce 8800 GTS (G80) 320MB has core clock speeds of 513 MHz on the GPU, and 792 MHz on the 320 MB of GDDR3 memory. It features 96 SPUs along with 48 TAUs and 20 ROPs.Compare those specs to the Radeon HD 3870 X2 512MB, which makes use of a 55 nm design. AMD has set the core speed at 825 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this particular card. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3870 X2 512MB should in theory be a lot faster than the GeForce 8800 GTS (G80) 320MB in general. (explain)
Texel RateThe Radeon HD 3870 X2 512MB will be a little bit (more or less 7%) better at texture filtering than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 3870 X2 512MB is the winner, by a large margin. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.

One Response to “GeForce 8800 GTS (G80) 320MB vs Radeon HD 3870 X2 512MB”[...] led me to beleive other wise, This is my old card, the 8800 gts and the 3870 x2 down from mine http://www.hwcompare.com/4846/geforc...3870-x2-512mb/ (iv put the 512mb on in here as that shows the game benchmarks) To me that seems like a pretty [...]
