Radeon R7 M360 vs Radeon R9 285

Intro

Compare all of that to the Radeon R9 285, which makes use of a 28 nm design. AMD has clocked the core speed at 918 MHz. The GDDR5 memory is set to run at a speed of 1375 MHz on this particular model. It features 1792 SPUs as well as 112 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 285 should in theory be a lot better than the Radeon R7 M360 overall. (explain)

Radeon R9 285		176000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 160000 (1000%)

Texel Rate

The Radeon R9 285 is a lot (more or less 281%) faster with regards to anisotropic filtering than the Radeon R7 M360. (explain)

Radeon R9 285		102816 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 75816 (281%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 285 is a better choice, and very much so. (explain)

Radeon R9 285		29376 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 20376 (226%)

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 max amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per 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 filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
