Compare any two graphics cards:
Radeon HD 6750 vs Radeon HD 7750
IntroThe Radeon HD 6750 makes use of a 40 nm design. ATi has clocked the core speed at 725 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this particular card. It features 720 SPUs as well as 36 TAUs and 16 Rasterization Operator Units.
Compare those specifications to the Radeon HD 7750, which makes use of a 28 nm design. ATi has clocked the core speed at 800 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this specific model. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 7750 should be 13% faster than the Radeon HD 6750 in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 6750 will be a bit (approximately 2%) more effective at texture filtering than the Radeon HD 7750. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 7750 is superior to the Radeon HD 6750, though only just barely. (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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the graphics card could 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
