Radeon R7 360 vs Radeon R9 M280X

Intro

Compare that to the Radeon R9 M280X, which features core clock speeds of 900 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M280X		75 Watts
Radeon R7 360		100 Watts
	Difference: 25 Watts (33%)

Memory Bandwidth

In theory, the Radeon R7 360 is 18% faster than the Radeon R9 M280X overall, because of its greater data rate. (explain)

Radeon R7 360		104000 MB/sec
Radeon R9 M280X		88000 MB/sec
	Difference: 16000 (18%)

Texel Rate

Both cards have the exact same texel rate, so in theory they should perform equally good at at AF. (explain)

Pixel Rate

The Radeon R7 360 will be a little bit (approximately 17%) better at AA than the Radeon R9 M280X, and able to handle higher screen resolutions while still performing well. (explain)

Radeon R7 360		16800 Mpixels/sec
Radeon R9 M280X		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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
