GeForce 940M vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The DDR3 memory runs at a speed of 1100 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

Theoretically speaking, the Radeon R9 M375 will be 120% faster than the GeForce 940M in general, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon R9 M375 should be a lot (more or less 58%) more effective at anisotropic filtering than the GeForce 940M. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M375 is the winner, 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 max amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
