GeForce GTX 970 vs Radeon R9 M375X

Intro

The GeForce GTX 970 makes use of a 28 nm design. nVidia has clocked the core frequency at 1050 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular card. It features 1664 SPUs along with 104 Texture Address Units and 64 Rasterization Operator Units.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 970 should in theory be quite a bit superior to 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 quite a bit (approximately 169%) more effective at AF than the Radeon R9 M375X. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 970 is a better choice, by far. (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 processed in one second. This figure 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 ability to reach the maximum fill rate.
