Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTS 450 1GB
IntroThe GeForce 8600 GT 512MB DDR2 comes with core clock speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the GeForce GTS 450 1GB, which comes with a clock frequency of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It is comprised of 192 SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTS 450 1GB should theoretically be much better than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce GTS 450 1GB will be a lot (approximately 190%) more effective at AF than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe GeForce GTS 450 1GB will be quite a bit (approximately 190%) more effective at anti-aliasing than the GeForce 8600 GT 512MB DDR2, and should be capable of handling higher screen resolutions while still performing well. (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 max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
