Nvidia Titan X vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which has GPU core speed of 1015 MHz, and 4096 MB of DDR3 RAM running at 1100 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Nvidia Titan X should in theory perform quite a bit 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 much (more or less 682%) better at AF 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 high levels of AA 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 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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 ability to reach the maximum fill rate.
