Radeon R9 270 vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which comes with GPU clock speed of 925 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 270 should be 149% quicker than the Radeon R9 M365X in general, because of its higher bandwidth. (explain)

Radeon R9 270		179200 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 107200 (149%)

Texel Rate

The Radeon R9 270 should be much (approximately 95%) faster with regards to texture filtering than the Radeon R9 M365X. (explain)

Radeon R9 270		72000 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 35000 (95%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 270 is superior to the Radeon R9 M365X, by far. (explain)

Radeon R9 270		28800 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 14000 (95%)

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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 can be applied in one second. This number is calculated by multiplying the total number of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
