GeForce 940M vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory works at a speed of 1125 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M370X should theoretically be a lot superior to the GeForce 940M in general. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M370X will be much (more or less 24%) faster with regards to AF than the GeForce 940M. (explain)

Radeon R9 M370X		32000 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 6272 (24%)

Pixel Rate

The Radeon R9 M370X will be quite a bit (about 49%) faster with regards to full screen anti-aliasing than the GeForce 940M, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 4224 (49%)

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 (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
