Radeon HD 6750 vs Radeon HD 7750

Intro

The Radeon HD 6750 comes with core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 720 SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

Compare all of that to the Radeon HD 7750, which comes with a clock speed of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Radeon HD 7750 72000 MB/sec
Radeon HD 6750 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon HD 6750 is a small bit (approximately 2%) faster with regards to anisotropic filtering than the Radeon HD 7750. (explain)

Radeon HD 6750 26100 Mtexels/sec
Radeon HD 7750 25600 Mtexels/sec
Difference: 500 (2%)

Pixel Rate

The Radeon HD 7750 will be a bit (approximately 10%) faster with regards to AA than the Radeon HD 6750, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 7750 12800 Mpixels/sec
Radeon HD 6750 11600 Mpixels/sec
Difference: 1200 (10%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 amount 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 number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
