GeForce GTX Titan X vs Radeon R9 M375

Intro

Compare those specs to the Radeon R9 M375, which features core speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX Titan X should in theory be quite a bit superior to the Radeon R9 M375 in general. (explain)

GeForce GTX Titan X		336000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 300800 (855%)

Texel Rate

The GeForce GTX Titan X should be a lot (more or less 373%) better at texture filtering than the Radeon R9 M375. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 151400 (373%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan X is a better choice, by a large margin. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 79760 (491%)

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 data (measured in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
