GeForce GTX Titan vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which features a GPU core clock speed of 800 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan should in theory be much faster than the Radeon R9 M370X overall. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 216384 (301%)

Texel Rate

The GeForce GTX Titan will be quite a bit (about 486%) more effective at texture filtering than the Radeon R9 M370X. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 155488 (486%)

Pixel Rate

The GeForce GTX Titan is a lot (more or less 214%) better at AA than the Radeon R9 M370X, and should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 27376 (214%)

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 largest amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
