Radeon R7 360 vs Radeon R9 M275X

Intro

Compare all of that to the Radeon R9 M275X, which makes use of a 28 nm design. AMD has set the core speed at 900 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Radeon R9 M275X		50 Watts
Radeon R7 360		100 Watts
	Difference: 50 Watts (100%)

Memory Bandwidth

The Radeon R7 360 should theoretically perform much faster than the Radeon R9 M275X overall. (explain)

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

Texel Rate

The Radeon R7 360 should be quite a bit (approximately 40%) better 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 lots of anti-aliasing is important to you, then the Radeon R7 360 is a better choice, though 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 (in units of MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
