Radeon R7 370 2G vs Radeon R9 M295X

Intro

Compare all of that to the Radeon R9 M295X, which comes with a core clock speed of 750 MHz and a GDDR5 memory speed of 1375 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Radeon R9 M295X		96000 Mtexels/sec
Radeon R7 370 2G		62400 Mtexels/sec
	Difference: 33600 (54%)

Pixel Rate

The Radeon R7 370 2G is much (approximately 30%) faster with regards to AA than the Radeon R9 M295X, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 7200 (30%)

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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
