GeForce 940M vs Radeon HD 7750

Intro

Compare all of that to the Radeon HD 7750, which features a core clock speed of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 7750 should in theory be much better than the GeForce 940M overall. (explain)

Radeon HD 7750		72000 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The GeForce 940M will be a small bit (more or less 1%) more effective at anisotropic filtering than the Radeon HD 7750. (explain)

GeForce 940M		25728 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 128 (1%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 7750 is superior to the GeForce 940M, and very much so. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 4224 (49%)

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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
