Radeon HD 6750 vs Radeon HD 6750 1GB
Intro
The Radeon HD 6750 features core speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.Compare all that to the Radeon HD 6750 1GB, which features a clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 720 SPUs, 36 TAUs, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)
Texel Rate
Both cards have exactly the same texel fill rate, so in theory they should perform equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have exactly the same pixel fill rate, so theoretically they should perform equally good at at full screen anti-aliasing, and be capable of handling the same screen resolutions. (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.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
