Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GT 220 GDDR3 uses a 40 nm design. nVidia has clocked the core speed at 625 MHz. The GDDR3 memory runs at a frequency of 1012 MHz on this specific model. It features 48 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.
Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which features core clock speeds of 650 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 6570 (OEM) 2GB should in theory be a lot superior to the GeForce GT 220 GDDR3 in general. (explain)
Texel RateThe Radeon HD 6570 (OEM) 2GB will be quite a bit (about 56%) more effective at texture filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6570 (OEM) 2GB is superior to the GeForce GT 220 GDDR3, but 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.
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 largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be applied 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 in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
