Radeon R9 M375X vs Radeon R9 Nano

Intro

Compare those specs to the Radeon R9 Nano, which comes with a GPU core clock speed of 1000 MHz, and 4096 MB of HBM memory set to run at 500 MHz through a 4096-bit bus. It also features 4096 Stream Processors, 256 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 Nano should theoretically be much faster than the Radeon R9 M375X in general. (explain)

Radeon R9 Nano		512000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 440000 (611%)

Texel Rate

The Radeon R9 Nano will be quite a bit (more or less 531%) more effective at AF than the Radeon R9 M375X. (explain)

Radeon R9 Nano		256000 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 215400 (531%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 Nano is the winner, and very much so. (explain)

Radeon R9 Nano		64000 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 47760 (294%)

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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
