Radeon Pro Duo vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon Pro Duo should be quite a bit faster than the Radeon R9 M365X in general. (explain)

Radeon Pro Duo		1024000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 952000 (1322%)

Texel Rate

The Radeon Pro Duo is much (more or less 1284%) faster with regards to anisotropic filtering than the Radeon R9 M365X. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 475000 (1284%)

Pixel Rate

The Radeon Pro Duo is much (about 765%) more effective at AA than the Radeon R9 M365X, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon Pro Duo		128000 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 113200 (765%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
