Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GT 220 GDDR3 has a core clock frequency of 625 MHz and a GDDR3 memory frequency of 1012 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 48 SPUs, 16 Texture Address Units, and 8 ROPs.
Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which comes with a core clock speed of 650 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 6570 (OEM) 2GB should be much faster than the GeForce GT 220 GDDR3 overall. (explain)
Texel RateThe Radeon HD 6570 (OEM) 2GB should be much (about 56%) faster with regards to texture filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateThe Radeon HD 6570 (OEM) 2GB will be a bit (about 4%) more effective at full screen anti-aliasing than the GeForce GT 220 GDDR3, and also will be capable of handling higher screen resolutions more effectively. (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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 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, High Dynamic Range 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 worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
