Radeon HD 6750 vs Radeon R9 M375X

Intro

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

Compare those specifications to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X, in theory, should perform a small bit faster than the Radeon HD 6750 overall. (explain)

Radeon R9 M375X 72000 MB/sec
Radeon HD 6750 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M375X will be quite a bit (more or less 56%) better at AF than the Radeon HD 6750. (explain)

Radeon R9 M375X 40600 Mtexels/sec
Radeon HD 6750 26100 Mtexels/sec
Difference: 14500 (56%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375X is superior to the Radeon HD 6750, and very much so. (explain)

Radeon R9 M375X 16240 Mpixels/sec
Radeon HD 6750 11600 Mpixels/sec
Difference: 4640 (40%)

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 information (counted in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of 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 one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
