Radeon HD 6750 vs Radeon R9 M370X

Intro

Compare that to the Radeon R9 M370X, which features a GPU core clock speed of 800 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M370X will be 13% faster than the Radeon HD 6750 overall, due to its greater bandwidth. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X is quite a bit (approximately 23%) better at AF than the Radeon HD 6750. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 5900 (23%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M370X is a better choice, though not by far. (explain)

Radeon R9 M370X		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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that 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 amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
