Radeon R9 M365X vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which features a GPU core clock speed of 1090 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 should be 56% quicker than the Radeon R9 M365X in general, because of its higher bandwidth. (explain)

Radeon RX 460		112000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 40000 (56%)

Texel Rate

The Radeon RX 460 should be a lot (about 65%) better at anisotropic filtering than the Radeon R9 M365X. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 24040 (65%)

Pixel Rate

The Radeon RX 460 is a small bit (more or less 18%) more effective at AA than the Radeon R9 M365X, and should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 2640 (18%)

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 max amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
