Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 5670
IntroThe GeForce GT 220 GDDR3 features a core clock frequency of 625 MHz and a GDDR3 memory frequency of 1012 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It features 48 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 5670, which uses a 40 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular model. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5670, in theory, should perform much faster than the GeForce GT 220 GDDR3 overall. (explain)
Texel RateThe Radeon HD 5670 should be much (approximately 55%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 5670 is superior to the GeForce GT 220 GDDR3, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
