Compare any two graphics cards:
Radeon HD 5850 vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 5850 comes with a clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It features 1440(288x5) SPUs, 72 TAUs, and 32 Raster Operation Units.
Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which has 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 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon HD 5850 should theoretically be a lot better than the Radeon HD 6570 (OEM) 2GB overall. (explain)
Texel RateThe Radeon HD 5850 should be a lot (more or less 235%) more effective at AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe Radeon HD 5850 should be much (about 346%) better at full screen anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and also capable of handling higher resolutions without slowing down too much. (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 maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 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 speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the 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 the core 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
