GeForce 940M vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which comes with core clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375 should theoretically be a lot faster than the GeForce 940M overall. (explain)

Radeon R9 M375		35200 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 19200 (120%)

Texel Rate

The Radeon R9 M375 will be quite a bit (more or less 58%) faster with regards to anisotropic filtering than the GeForce 940M. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 14872 (58%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375 is superior to the GeForce 940M, and very much so. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 7664 (89%)

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 transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling 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 could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
