Compare any two graphics cards:
Radeon HD 6770 1GB vs Radeon HD 7750
IntroThe Radeon HD 6770 1GB uses a 40 nm design. ATi has set the core frequency at 900 MHz. The GDDR5 memory runs at a frequency of 1050 MHz on this particular card. It features 800 SPUs along with 40 TAUs and 16 ROPs.
Compare those specs to the Radeon HD 7750, which features GPU core speed of 800 MHz, and 1024 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 7750 should theoretically perform a bit faster than the Radeon HD 6770 1GB in general. (explain)
Texel RateThe Radeon HD 6770 1GB is a lot (more or less 41%) better at texture filtering than the Radeon HD 7750. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6770 1GB is a better choice, though not 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.
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 largest amount of data (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core 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 in one second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
