GeForce 940M vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which has GPU core speed of 825 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260X is 300% faster than the GeForce 940M overall, due to its greater bandwidth. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The GeForce 940M should be quite a bit (more or less 30%) more effective at AF than the Radeon R7 M260X. (explain)

GeForce 940M		25728 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 5928 (30%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 940M is a better choice, and very much so. (explain)

GeForce 940M		8576 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 1976 (30%)

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 (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at 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 card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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.
