Nvidia Titan X vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which comes with a GPU core clock speed of 1015 MHz, and 4096 MB of DDR3 RAM set to run at 1100 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X is 1296% faster than the Radeon R9 M375 in general, because of its higher data rate. (explain)

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

Texel Rate

The Nvidia Titan X is much (about 682%) more effective at anisotropic 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 using lots of anti-aliasing is important to you, then the Nvidia Titan X is a better choice, by a large margin. (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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
