Radeon HD 6750 vs Radeon R9 M370X

Intro

The Radeon HD 6750 comes with 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 features 720 Stream Processors, 36 TAUs, and 16 Raster Operation Units.

Compare those specs to the Radeon R9 M370X, which uses a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this 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% quicker than the Radeon HD 6750 overall, due to 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 using high levels of AA is important to you, then the Radeon R9 M370X is a better choice, but only just. (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.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
