Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs GeForce GT 220 GDDR3
IntroThe GeForce 8600 GT 512MB GDDR3 comes with clock speeds of 540 MHz on the GPU, and 700 MHz on the 512 MB of GDDR3 memory. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the GeForce GT 220 GDDR3, which has a core clock frequency of 625 MHz and a GDDR3 memory frequency of 1012 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 48 SPUs, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 220 GDDR3 should in theory perform a lot faster than the GeForce 8600 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce GT 220 GDDR3 will be a little bit (approximately 16%) more effective at anisotropic filtering than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateThe GeForce GT 220 GDDR3 will be a bit (approximately 16%) faster with regards to full screen anti-aliasing than the GeForce 8600 GT 512MB GDDR3, and also should be able to handle higher 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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once 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 anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
