GeForce GTX 950 vs Radeon R9 M375X

Intro

Compare those specs to the Radeon R9 M375X, which comes with clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 950 should be a lot faster than the Radeon R9 M375X in general. (explain)

GeForce GTX 950		105728 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 33728 (47%)

Texel Rate

The GeForce GTX 950 is quite a bit (more or less 21%) better at AF than the Radeon R9 M375X. (explain)

GeForce GTX 950		49152 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 8552 (21%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 950 is the winner, and very much so. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 16528 (102%)

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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
