GeForce GTX 960M vs Radeon HD 6750 1GB

Intro

Compare 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 works at a frequency of 1000 MHz on this card. It features 720 SPUs as well as 36 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960M		65 Watts
Radeon HD 6750 1GB		86 Watts
	Difference: 21 Watts (32%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The GeForce GTX 960M will be quite a bit (approximately 68%) more effective at anisotropic filtering than the Radeon HD 6750 1GB. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 17740 (68%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 960M is the winner, and very much so. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 5936 (51%)

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 megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
