GeForce GTX Titan vs Radeon R9 M365X

Intro

The GeForce GTX Titan uses a 28 nm design. nVidia has set the core speed at 837 MHz. The GDDR5 RAM is set to run at a frequency of 1502 MHz on this card. It features 2688 SPUs along with 224 TAUs and 48 ROPs.

Compare all of that to the Radeon R9 M365X, which features GPU core speed of 925 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan should be 301% faster than the Radeon R9 M365X overall, due to its greater data rate. (explain)

GeForce GTX Titan 288384 MB/sec
Radeon R9 M365X 72000 MB/sec
Difference: 216384 (301%)

Texel Rate

The GeForce GTX Titan should be quite a bit (about 407%) faster with regards to anisotropic filtering than the Radeon R9 M365X. (explain)

GeForce GTX Titan 187488 Mtexels/sec
Radeon R9 M365X 37000 Mtexels/sec
Difference: 150488 (407%)

Pixel Rate

If running with 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 M365X 14800 Mpixels/sec
Difference: 25376 (171%)

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 maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 applied in one 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 the texel rate, the better the graphics 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 could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
