Radeon R7 M360 vs Radeon R9 M275X

Intro

Compare that to the Radeon R9 M275X, which features a core clock frequency of 900 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M275X should be much faster than the Radeon R7 M360 overall. (explain)

Radeon R9 M275X		72000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M275X should be much (approximately 33%) more effective at texture filtering than the Radeon R7 M360. (explain)

Radeon R9 M275X		36000 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 9000 (33%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M275X is superior to the Radeon R7 M360, and very much so. (explain)

Radeon R9 M275X		14400 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 5400 (60%)

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 maximum amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
