Radeon R9 M280X vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which comes with a clock speed of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M280X should be much faster than the Radeon R9 M370X overall. (explain)

Radeon R9 M280X		88000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 16000 (22%)

Texel Rate

The Radeon R9 M280X should be a lot (more or less 58%) better at texture filtering than the Radeon R9 M370X. (explain)

Radeon R9 M280X		50400 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 18400 (58%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M280X is a better choice, though not by far. (explain)

Radeon R9 M280X		14400 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 1600 (13%)

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 MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
