GeForce GTX Titan Black vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which features GPU core speed of 1015 MHz, and 4096 MB of DDR3 RAM running at 1100 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan Black should be 855% faster than the Radeon R9 M375 in general, because of its higher bandwidth. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 300800 (855%)

Texel Rate

The GeForce GTX Titan Black will be quite a bit (more or less 426%) faster with regards to anisotropic filtering than the Radeon R9 M375. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 172760 (426%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan Black is the winner, by far. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon R9 M375		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 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 card's bus width by the speed of its memory. 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 faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
