Compare any two graphics cards:
Radeon HD 5750 1GB vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 5750 1GB has core clock speeds of 700 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 ROPs.
Compare those specs to the Radeon HD 6570 (OEM) 2GB, which has GPU core speed of 650 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also features 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 5750 1GB should theoretically perform a little bit faster than the Radeon HD 6570 (OEM) 2GB overall. (explain)
Texel RateThe Radeon HD 5750 1GB will be quite a bit (approximately 62%) faster with regards to anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe Radeon HD 5750 1GB should be quite a bit (more or less 115%) more effective at full screen anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and able to handle higher resolutions while still performing well. (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 (in units of MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 are applied per second. This number is worked out by multiplying the total texture units by the core clock 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 applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
