GeForce GTX Titan X vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which comes with GPU clock 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 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan X should theoretically perform much faster than 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 quite a bit (more or less 373%) faster with regards to AF than the Radeon R9 M375. (explain)

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

Pixel Rate

The GeForce GTX Titan X is quite a bit (about 491%) more effective at full screen anti-aliasing than the Radeon R9 M375, and should be able to handle higher resolutions more effectively. (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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the 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 most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
