Nvidia Titan X vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which features GPU core speed of 1015 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Nvidia Titan X should in theory be much superior to the Radeon R9 M375X overall. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 419520 (583%)

Texel Rate

The Nvidia Titan X should be much (approximately 682%) more effective at texture filtering than the Radeon R9 M375X. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 276808 (682%)

Pixel Rate

If running with a high resolution is important to you, then the Nvidia Titan X is the winner, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 119792 (738%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
