GeForce GTX Titan vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which comes with GPU core speed of 925 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX Titan will be 301% quicker than the Radeon R9 M365X overall, due to its greater bandwidth. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 216384 (301%)

Texel Rate

The GeForce GTX Titan is a lot (more or less 407%) faster with regards to anisotropic filtering than the Radeon R9 M365X. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 150488 (407%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan is a better choice, by far. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 25376 (171%)

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 information (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
