Radeon R7 M360 vs Radeon R9 M280X

Intro

Compare all of that to the Radeon R9 M280X, which has GPU core speed of 900 MHz, and 4096 MB of GDDR5 RAM running at 1375 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M280X should in theory perform quite a bit faster than the Radeon R7 M360 in general. (explain)

Radeon R9 M280X		88000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 72000 (450%)

Texel Rate

The Radeon R9 M280X is a lot (more or less 87%) more effective at AF than the Radeon R7 M360. (explain)

Radeon R9 M280X		50400 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 23400 (87%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M280X is the winner, by a large margin. (explain)

Radeon R9 M280X		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 largest amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on 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 bandwidth is, the lower the ability to reach the maximum fill rate.
