Radeon R9 295X2 vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 295X2 should be much faster than the Radeon R9 M375X in general. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 568000 (789%)

Texel Rate

The Radeon R9 295X2 is a lot (more or less 783%) better at AF than the Radeon R9 M375X. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 317736 (783%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 295X2 is the winner, by far. (explain)

Radeon R9 295X2		130304 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 114064 (702%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
