Radeon R7 360 vs Radeon R9 M280X

Intro

Compare those specifications to the Radeon R9 M280X, which has a GPU core clock speed of 900 MHz, and 4096 MB of GDDR5 memory running at 1375 MHz through a 128-bit bus. It also features 896 Stream Processors, 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

The Radeon R7 360, in theory, should be a small bit faster than the Radeon R9 M280X overall. (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 theoretically they should perform equally good at at AF. (explain)

Pixel Rate

The Radeon R7 360 will be a bit (more or less 17%) more effective at full screen anti-aliasing than the Radeon R9 M280X, and also will be capable of handling higher screen resolutions better. (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 information (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
