Radeon R9 M295X vs Radeon R9 M370X

Intro

Compare that to the Radeon R9 M370X, which features a GPU core clock speed of 800 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X is 144% quicker than the Radeon R9 M370X in general, due to its greater data rate. (explain)

Radeon R9 M295X		176000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 104000 (144%)

Texel Rate

The Radeon R9 M295X will be much (more or less 200%) faster with regards to AF than the Radeon R9 M370X. (explain)

Radeon R9 M295X		96000 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 64000 (200%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M295X is the winner, by a large margin. (explain)

Radeon R9 M295X		24000 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 11200 (88%)

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 (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should 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 high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
