Radeon HD 6750 1GB vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which uses a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M370X will be 13% faster than the Radeon HD 6750 1GB in general, due to its greater bandwidth. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 6750 1GB		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X should be a lot (about 23%) better at texture filtering than the Radeon HD 6750 1GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 5900 (23%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M370X is the winner, though only just barely. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 6750 1GB		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 maximum amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
