Nvidia Titan Xp vs Radeon R9 M265X

Intro

Compare all that to the Radeon R9 M265X, which features core speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Nvidia Titan Xp should theoretically be quite a bit better than the Radeon R9 M265X overall. (explain)

Nvidia Titan Xp		560845 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 488845 (679%)

Texel Rate

The Nvidia Titan Xp will be much (more or less 1551%) more effective at texture filtering than the Radeon R9 M265X. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 356680 (1551%)

Pixel Rate

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

Nvidia Titan Xp		151872 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 142672 (1551%)

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 maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
