Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs Radeon HD 7770
IntroThe GeForce 8600 GT 512MB GDDR3 makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 memory runs at a speed of 700 MHz on this specific model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specs to the Radeon HD 7770, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7770 should be much faster than the GeForce 8600 GT 512MB GDDR3 in general. (explain)
Texel RateThe Radeon HD 7770 will be quite a bit (about 363%) better at texture filtering than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateThe Radeon HD 7770 should be quite a bit (more or less 270%) faster with regards to anti-aliasing than the GeForce 8600 GT 512MB GDDR3, and also will be able to handle higher screen resolutions without losing too much performance. (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 (measured in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
