Radeon R9 M365X vs Radeon RX 480

Intro

Compare all of that to the Radeon RX 480, which makes use of a 14 nm design. AMD has set the core speed at 1120 MHz. The GDDR5 memory works at a speed of 2000 MHz on this card. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 480 should in theory be quite a bit superior to the Radeon R9 M365X in general. (explain)

Radeon RX 480		262144 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 190144 (264%)

Texel Rate

The Radeon RX 480 should be much (about 336%) faster with regards to texture filtering than the Radeon R9 M365X. (explain)

Radeon RX 480		161280 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 124280 (336%)

Pixel Rate

The Radeon RX 480 should be quite a bit (approximately 142%) faster with regards to AA than the Radeon R9 M365X, and will be able to handle higher resolutions while still performing well. (explain)

Radeon RX 480		35840 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 21040 (142%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
