Radeon R7 360 vs Radeon R9 M275X

Intro

Compare that to the Radeon R9 M275X, which has GPU clock speed of 900 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

	Difference: 50 Watts (100%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 360 is 44% faster than the Radeon R9 M275X in general, due to its greater bandwidth. (explain)

Radeon R7 360		104000 MB/sec
Radeon R9 M275X		72000 MB/sec
	Difference: 32000 (44%)

Texel Rate

The Radeon R7 360 will be much (approximately 40%) more effective at anisotropic filtering than the Radeon R9 M275X. (explain)

Radeon R7 360		50400 Mtexels/sec
Radeon R9 M275X		36000 Mtexels/sec
	Difference: 14400 (40%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 360 is superior to the Radeon R9 M275X, but not by far. (explain)

Radeon R7 360		16800 Mpixels/sec
Radeon R9 M275X		14400 Mpixels/sec
	Difference: 2400 (17%)

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 largest amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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