Compare any two graphics cards:
Radeon HD 5850 vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 5850 makes use of a 40 nm design. ATi has set the core frequency at 725 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific card. It features 1440(288x5) SPUs as well as 72 Texture Address Units and 32 Rasterization Operator Units.
Compare all of that to the Radeon HD 6570 (OEM) 1GB, which has GPU clock speed of 650 MHz, and 1024 MB of GDDR3 memory running at 900 MHz through a 128-bit bus. It also features 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 5850 should perform much faster than the Radeon HD 6570 (OEM) 1GB in general. (explain)
Texel RateThe Radeon HD 5850 will be much (approximately 235%) more effective at anisotropic filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 5850 is superior to the Radeon HD 6570 (OEM) 1GB, by a large margin. (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 megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
