Nvidia Titan Xp vs Radeon R9 M385X

Intro

Compare those specifications to the Radeon R9 M385X, which comes with GPU core speed of 1100 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Nvidia Titan Xp should in theory perform much faster than the Radeon R9 M385X overall. (explain)

Nvidia Titan Xp		560845 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 464845 (484%)

Texel Rate

The Nvidia Titan Xp is quite a bit (more or less 516%) more effective at texture filtering than the Radeon R9 M385X. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 318080 (516%)

Pixel Rate

The Nvidia Titan Xp will be a lot (more or less 763%) better at FSAA than the Radeon R9 M385X, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 134272 (763%)

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 (counted in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
