GeForce GTX 965M vs Radeon HD 6750

Intro

Compare those specs to the Radeon HD 6750, which features core speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 720 SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 965M		60 Watts
Radeon HD 6750		86 Watts
	Difference: 26 Watts (43%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 965M should be much (about 131%) better at anisotropic filtering than the Radeon HD 6750. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 34316 (131%)

Pixel Rate

The GeForce GTX 965M will be quite a bit (more or less 160%) faster with regards to FSAA than the Radeon HD 6750, and also able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 18608 (160%)

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 MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant 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.
