Radeon R9 M365X vs Radeon R9 Nano

Intro

Compare all that to the Radeon R9 Nano, which features a clock frequency of 1000 MHz and a HBM memory speed of 500 MHz. It also makes use of a 4096-bit bus, and uses a 28 nm design. It is made up of 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 Nano should be 611% quicker than the Radeon R9 M365X overall, due to its higher bandwidth. (explain)

Radeon R9 Nano		512000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 440000 (611%)

Texel Rate

The Radeon R9 Nano is quite a bit (about 592%) more effective at texture filtering than the Radeon R9 M365X. (explain)

Radeon R9 Nano		256000 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 219000 (592%)

Pixel Rate

The Radeon R9 Nano should be a lot (more or less 332%) more effective at AA than the Radeon R9 M365X, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 Nano		64000 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 49200 (332%)

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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
