GeForce 940M vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which has a GPU core clock speed of 925 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X, in theory, should perform quite a bit faster than the GeForce 940M overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M365X will be much (approximately 44%) more effective at AF than the GeForce 940M. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 11272 (44%)

Pixel Rate

The Radeon R9 M365X is quite a bit (about 73%) better at anti-aliasing than the GeForce 940M, and also will be capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 6224 (73%)

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 data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses 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 amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, 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 maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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.
