Radeon HD 6750 vs Radeon HD 6770 1GB

Intro

The Radeon HD 6750 comes with a GPU core clock speed of 725 MHz, and the 512 MB of GDDR5 RAM is set to run at 1000 MHz through a 128-bit bus. It also is made up of 720 Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the Radeon HD 6770 1GB, which comes with GPU core speed of 900 MHz, and 1024 MB of GDDR5 RAM running at 1050 MHz through a 128-bit bus. It also is comprised of 800 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Radeon HD 6770 1GB 67200 MB/sec
Radeon HD 6750 64000 MB/sec
Difference: 3200 (5%)

Texel Rate

The Radeon HD 6770 1GB is a lot (about 38%) faster with regards to texture filtering than the Radeon HD 6750. (explain)

Radeon HD 6770 1GB 36000 Mtexels/sec
Radeon HD 6750 26100 Mtexels/sec
Difference: 9900 (38%)

Pixel Rate

The Radeon HD 6770 1GB is much (approximately 24%) more effective at AA than the Radeon HD 6750, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon HD 6770 1GB 14400 Mpixels/sec
Radeon HD 6750 11600 Mpixels/sec
Difference: 2800 (24%)

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 max amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
