GeForce GTX 960M vs Radeon HD 6750

Intro

Compare those specs to the Radeon HD 6750, which has core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. 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		86 Watts
	Difference: 21 Watts (32%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The GeForce GTX 960M should be a lot (about 68%) more effective at anisotropic filtering than the Radeon HD 6750. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 960M is a better choice, by far. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon HD 6750		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: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
