Radeon R7 M360 vs Radeon R9 M270X

Intro

Compare those specifications to the Radeon R9 M270X, which has a clock frequency of 725 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M270X should in theory be a lot superior to the Radeon R7 M360 overall. (explain)

Radeon R9 M270X		72000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M270X is a small bit (more or less 7%) more effective at AF than the Radeon R7 M360. (explain)

Radeon R9 M270X		29000 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 2000 (7%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M270X is the winner, by a large margin. (explain)

Radeon R9 M270X		11600 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 2600 (29%)

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 megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
