Radeon HD 6750 vs Radeon R9 M370X

Intro

Compare that to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory works at a speed of 1125 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M370X will be 13% faster than the Radeon HD 6750 overall, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon R9 M370X will be much (about 23%) faster with regards to texture filtering 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 a high resolution is important to you, then the Radeon R9 M370X is superior to the Radeon HD 6750, but it probably won't make a huge difference. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
