GeForce 940M vs Radeon HD 5750 1GB

Intro

Compare that to the Radeon HD 5750 1GB, which features a core clock frequency of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It features 720(144x5) SPUs, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 5750 1GB should theoretically be quite a bit better than the GeForce 940M overall. (explain)

Radeon HD 5750 1GB		73600 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 57600 (360%)

Texel Rate

The GeForce 940M will be a bit (approximately 2%) faster with regards to texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce 940M		25728 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 528 (2%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5750 1GB is a better choice, by a large margin. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 2624 (31%)

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 MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, 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 number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
