Nvidia Titan X vs Radeon R9 Nano

Intro

The Nvidia Titan X features a GPU clock speed of 1417 MHz, and the 12288 MB of GDDR5X RAM is set to run at 1251 MHz through a 384-bit bus. It also is made up of 3584 Stream Processors, 224 TAUs, and 96 ROPs.

Compare those specs to the Radeon R9 Nano, which has clock speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM RAM. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

Radeon R9 Nano 512000 MB/sec
Nvidia Titan X 491520 MB/sec
Difference: 20480 (4%)

Texel Rate

The Nvidia Titan X should be quite a bit (about 24%) faster with regards to AF than the Radeon R9 Nano. (explain)

Nvidia Titan X 317408 Mtexels/sec
Radeon R9 Nano 256000 Mtexels/sec
Difference: 61408 (24%)

Pixel Rate

The Nvidia Titan X should be a lot (approximately 113%) more effective at anti-aliasing than the Radeon R9 Nano, and also capable of handling higher resolutions without slowing down too much. (explain)

Nvidia Titan X 136032 Mpixels/sec
Radeon R9 Nano 64000 Mpixels/sec
Difference: 72032 (113%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
