Compare any two graphics cards:
Radeon HD 5850 vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 5850 has a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It is comprised of 1440(288x5) SPUs, 72 Texture Address Units, and 32 Raster Operation Units.
Compare that to the Radeon HD 6570 (OEM) 1GB, which comes with a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and uses 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)
Performance-wise, the Radeon HD 5850 should in theory be much better than the Radeon HD 6570 (OEM) 1GB in general. (explain)
Texel RateThe Radeon HD 5850 is quite a bit (about 235%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 5850 should be much (approximately 346%) better at FSAA than the Radeon HD 6570 (OEM) 1GB, and also should be capable of handling higher screen 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 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: Bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
