Radeon R9 M265X vs Radeon R9 Nano

Intro

The Radeon R9 M265X has clock speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Compare all that to the Radeon R9 Nano, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The HBM RAM is set to run at a frequency of 500 MHz on this specific card. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 Nano is 611% quicker than the Radeon R9 M265X overall, due to its higher bandwidth. (explain)

Radeon R9 Nano 512000 MB/sec
Radeon R9 M265X 72000 MB/sec
Difference: 440000 (611%)

Texel Rate

The Radeon R9 Nano should be a lot (more or less 1013%) faster with regards to anisotropic filtering than the Radeon R9 M265X. (explain)

Radeon R9 Nano 256000 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 233000 (1013%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 Nano is the winner, by far. (explain)

Radeon R9 Nano 64000 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 54800 (596%)

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 max amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
