GeForce GTX Titan Black vs Radeon R9 M375

Intro

Compare those specs to the Radeon R9 M375, which comes with a core clock frequency of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX Titan Black should theoretically be much superior to the Radeon R9 M375 overall. (explain)

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

Texel Rate

The GeForce GTX Titan Black should be quite a bit (more or less 426%) better at AF 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 lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is the winner, and very much so. (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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount 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 fill rate also depends 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 maximum fill rate.
