Nvidia Titan X vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which features a core clock frequency of 1015 MHz and a DDR3 memory frequency of 1100 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X should be much faster than the Radeon R9 M375 in general. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 456320 (1296%)

Texel Rate

The Nvidia Titan X should be quite a bit (more or less 682%) better at texture filtering than the Radeon R9 M375. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 276808 (682%)

Pixel Rate

If running with high levels of AA is important to you, then the Nvidia Titan X is superior to the Radeon R9 M375, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R9 M375		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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. 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 higher the card's memory bandwidth, the better 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 worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
