GeForce 940M vs Radeon HD 6750 1GB

Intro

Compare all that to the Radeon HD 6750 1GB, which uses a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific model. It features 720 SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 6750 1GB should theoretically perform a lot faster than the GeForce 940M overall. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon HD 6750 1GB will be a bit (approximately 1%) better at texture filtering than the GeForce 940M. (explain)

Radeon HD 6750 1GB		26100 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 372 (1%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6750 1GB is the winner, by a large margin. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 3024 (35%)

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 information (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
