GeForce GTX Titan vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which has a clock frequency of 1015 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX Titan should in theory be a lot better than the Radeon R9 M375X overall. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 216384 (301%)

Texel Rate

The GeForce GTX Titan is much (approximately 362%) better at anisotropic filtering than the Radeon R9 M375X. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 146888 (362%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan is a better choice, and very much so. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 23936 (147%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
