Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GTX 470 comes with a clock speed of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also features a 320-bit memory bus, and uses a 40 nm design. It is comprised of 448 SPUs, 56 TAUs, and 40 ROPs.
Compare all that to the Radeon HD 6570 (OEM) 2GB, which comes with core clock speeds of 650 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 470 should theoretically be much better than the Radeon HD 6570 (OEM) 2GB in general. (explain)
Texel RateThe GeForce GTX 470 should be quite a bit (more or less 118%) better at AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe GeForce GTX 470 should be quite a bit (approximately 367%) faster with regards to AA than the Radeon HD 6570 (OEM) 2GB, and also capable of handling higher resolutions better. (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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If 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, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
