Compare any two graphics cards:
Radeon HD 6570 (OEM) 2GB vs Radeon HD 7750
IntroThe Radeon HD 6570 (OEM) 2GB uses a 40 nm design. ATi has clocked the core frequency at 650 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this card. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.
Compare those specifications to the Radeon HD 7750, which makes use of a 28 nm design. ATi has clocked the core frequency at 800 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific card. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 7750 should theoretically be a little bit faster than the Radeon HD 6570 (OEM) 2GB overall. (explain)
Texel RateThe Radeon HD 7750 is quite a bit (more or less 64%) more effective at anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 7750 is the winner, and very much so. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should 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, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 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 reach the max fill rate.
