GeForce GTX 970 vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which features a core clock frequency of 1015 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 970 should in theory be a lot faster than the Radeon R9 M375X overall. (explain)

GeForce GTX 970		224000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 152000 (211%)

Texel Rate

The GeForce GTX 970 is much (more or less 169%) faster with regards to anisotropic filtering than the Radeon R9 M375X. (explain)

GeForce GTX 970		109200 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 68600 (169%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 970 is superior to the Radeon R9 M375X, and very much so. (explain)

GeForce GTX 970		67200 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 50960 (314%)

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 data (counted in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
