Radeon HD 6750 vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which comes with core clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375X should be 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 is much (about 56%) better at anisotropic filtering than the Radeon HD 6750. (explain)

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

Pixel Rate

If using a high screen resolution 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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
