Nvidia Titan X vs Radeon R9 M385X

Intro

Compare those specs to the Radeon R9 M385X, which has a core clock speed of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Nvidia Titan X should in theory be much superior to the Radeon R9 M385X overall. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 395520 (412%)

Texel Rate

The Nvidia Titan X will be a lot (approximately 415%) better at anisotropic filtering than the Radeon R9 M385X. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 255808 (415%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Nvidia Titan X is superior to the Radeon R9 M385X, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 118432 (673%)

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 (counted in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
