Radeon R9 M370X vs Radeon R9 M375X

Intro

The Radeon R9 M370X has a GPU core clock speed of 800 MHz, and the 2048 MB of GDDR5 memory is set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 ROPs.

Compare all of that to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has set the core frequency at 1015 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon R9 M375X is a lot (approximately 27%) faster with regards to AF than the Radeon R9 M370X. (explain)

Radeon R9 M375X 40600 Mtexels/sec
Radeon R9 M370X 32000 Mtexels/sec
Difference: 8600 (27%)

Pixel Rate

The Radeon R9 M375X will be much (approximately 27%) more effective at FSAA than the Radeon R9 M370X, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M375X 16240 Mpixels/sec
Radeon R9 M370X 12800 Mpixels/sec
Difference: 3440 (27%)

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 max amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at 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 could 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
