Nvidia Titan Xp vs Radeon R9 M270X

Intro

Compare all that to the Radeon R9 M270X, which comes with a core clock frequency of 725 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Nvidia Titan Xp should theoretically be much better than the Radeon R9 M270X overall. (explain)

Nvidia Titan Xp		560845 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 488845 (679%)

Texel Rate

The Nvidia Titan Xp should be much (approximately 1209%) faster with regards to AF than the Radeon R9 M270X. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 350680 (1209%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Nvidia Titan Xp is a better choice, by far. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 140272 (1209%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to 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 ability to reach the maximum fill rate.
