GeForce GTX Titan Black vs Radeon R9 M365X

Intro

The GeForce GTX Titan Black comes with a clock frequency of 889 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 2880 SPUs, 240 TAUs, and 48 ROPs.

Compare all that to the Radeon R9 M365X, which features a GPU core clock speed of 925 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan Black will be 367% quicker than the Radeon R9 M365X in general, because of its greater bandwidth. (explain)

GeForce GTX Titan Black 336000 MB/sec
Radeon R9 M365X 72000 MB/sec
Difference: 264000 (367%)

Texel Rate

The GeForce GTX Titan Black is a lot (approximately 477%) more effective at anisotropic filtering than the Radeon R9 M365X. (explain)

GeForce GTX Titan Black 213360 Mtexels/sec
Radeon R9 M365X 37000 Mtexels/sec
Difference: 176360 (477%)

Pixel Rate

The GeForce GTX Titan Black should be quite a bit (approximately 188%) faster with regards to AA than the Radeon R9 M365X, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX Titan Black 42672 Mpixels/sec
Radeon R9 M365X 14800 Mpixels/sec
Difference: 27872 (188%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
