GeForce GTX 960M vs Radeon HD 6750 1GB

Intro

Compare all of that to the Radeon HD 6750 1GB, which features a clock frequency of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It features 720 SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

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 exactly the same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The GeForce GTX 960M is much (more or less 68%) faster with regards to 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

The GeForce GTX 960M should be a lot (about 51%) better at anti-aliasing than the Radeon HD 6750 1GB, and able to handle higher screen resolutions without losing too much performance. (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
