Compare any two graphics cards:
Radeon HD 5850 vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 5850 comes with a core clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It features 1440(288x5) SPUs, 72 Texture Address Units, and 32 ROPs.
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 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 5850 should theoretically be quite a bit superior to the Radeon HD 6570 (OEM) 2GB overall. (explain)
Texel RateThe Radeon HD 5850 should be a lot (approximately 235%) better at texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe Radeon HD 5850 will be a lot (more or less 346%) more effective at full screen anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and should be capable of handling higher resolutions without losing too much performance. (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 maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
