Compare any two graphics cards:
GeForce 8800 GTX vs GeForce GTS 250 512MB
IntroThe GeForce 8800 GTX comes with a GPU core clock speed of 575 MHz, and the 768 MB of GDDR3 RAM runs at 900 MHz through a 384-bit bus. It also features 128 SPUs, 64 TAUs, and 24 Raster Operation Units.Compare all of that to the GeForce GTS 250 512MB, which features core speeds of 738 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 memory. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 8800 GTX should in theory be quite a bit faster than the GeForce GTS 250 512MB overall. (explain)
Texel RateThe GeForce GTS 250 512MB should be much (more or less 28%) more effective at anisotropic filtering than the GeForce 8800 GTX. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 8800 GTX is superior to the GeForce GTS 250 512MB, but it probably won't make a huge difference. (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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
