GeForce GTX 970 vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which comes with a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

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

Texel Rate

The GeForce GTX 970 should be quite a bit (more or less 169%) better 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

The GeForce GTX 970 is quite a bit (more or less 314%) better at FSAA than the Radeon R9 M375X, and capable of handling higher resolutions more effectively. (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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
