GeForce GTX Titan Black vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan Black, in theory, should perform much faster than the Radeon R9 M375X overall. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 264000 (367%)

Texel Rate

The GeForce GTX Titan Black should be much (approximately 426%) more effective at AF than the Radeon R9 M375X. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 172760 (426%)

Pixel Rate

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

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 26432 (163%)

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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
