Compare any two graphics cards:
Radeon HD 5750 1GB vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 5750 1GB makes use of a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory is set to run at a speed of 1150 MHz on this card. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.
Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which comes with core 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 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon HD 5750 1GB should be a little bit faster than the Radeon HD 6570 (OEM) 2GB in general. (explain)
Texel RateThe Radeon HD 5750 1GB will be quite a bit (approximately 62%) faster with regards to AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 5750 1GB is the winner, by far. (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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
