Radeon R7 360 vs Radeon R9 M280X

Intro

Compare that to the Radeon R9 M280X, which features GPU core speed of 900 MHz, and 4096 MB of GDDR5 RAM set to run at 1375 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

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

As far as performance goes, the Radeon R7 360 should theoretically be a little bit superior to the Radeon R9 M280X in general. (explain)

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

Texel Rate

Both cards have exactly the same texel fill rate, so theoretically they should be equally good at at anisotropic filtering. (explain)

Pixel Rate

The Radeon R7 360 is a small bit (approximately 17%) more effective at full screen anti-aliasing than the Radeon R9 M280X, and also able to handle higher screen resolutions without slowing down too much. (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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
