Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 5570
IntroThe GeForce GT 220 GDDR3 comes with a core clock speed of 625 MHz and a GDDR3 memory speed of 1012 MHz. It also uses a 128-bit 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 5570, which comes with GPU clock speed of 650 MHz, and 512 MB of DDR3 memory set to run at 900 MHz through a 128-bit bus. It also is comprised of 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GT 220 GDDR3 should in theory be a bit better than the Radeon HD 5570 in general. (explain)
Texel RateThe Radeon HD 5570 is much (approximately 30%) more effective at AF than the GeForce GT 220 GDDR3. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 5570 is a better choice, though not by far. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
