Nvidia Titan X vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X should perform much faster than the Radeon R9 M365X overall. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 419520 (583%)

Texel Rate

The Nvidia Titan X is quite a bit (approximately 758%) better at texture filtering than the Radeon R9 M365X. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 280408 (758%)

Pixel Rate

The Nvidia Titan X should be much (more or less 819%) faster with regards to AA than the Radeon R9 M365X, and should be able to handle higher screen resolutions better. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 121232 (819%)

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 (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock 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 better the card's memory bandwidth, the faster 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 can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
