GeForce 940M vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M365X should be 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 (more or less 73%) faster with regards to FSAA than the GeForce 940M, and will be able to handle higher screen resolutions better. (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 largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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