Compare any two graphics cards:
Radeon HD 5850 vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 5850 features a GPU core clock speed of 725 MHz, and the 1024 MB of GDDR5 memory is set to run at 1000 MHz through a 256-bit bus. It also is made up of 1440(288x5) Stream Processors, 72 TAUs, and 32 Raster Operation Units.
Compare those specs to the Radeon HD 6570 (OEM) 1GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular card. 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 5850 should in theory be a lot better than the Radeon HD 6570 (OEM) 1GB overall. (explain)
Texel RateThe Radeon HD 5850 is a lot (approximately 235%) more effective at texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 5850 will be much (more or less 346%) better at FSAA than the Radeon HD 6570 (OEM) 1GB, and also will be capable of handling higher screen 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
