GeForce GTX 950M vs Radeon HD 6750

Intro

The GeForce GTX 950M comes with a core clock frequency of 914 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Compare all that to the Radeon HD 6750, which uses a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this specific model. It features 720 SPUs as well as 36 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M 55 Watts
Radeon HD 6750 86 Watts
Difference: 31 Watts (56%)

Memory Bandwidth

In theory, the Radeon HD 6750 will be 100% faster than the GeForce GTX 950M overall, because of its greater bandwidth. (explain)

Radeon HD 6750 64000 MB/sec
GeForce GTX 950M 32000 MB/sec
Difference: 32000 (100%)

Texel Rate

The GeForce GTX 950M is quite a bit (more or less 40%) better at texture filtering than the Radeon HD 6750. (explain)

GeForce GTX 950M 36560 Mtexels/sec
Radeon HD 6750 26100 Mtexels/sec
Difference: 10460 (40%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 950M is a better choice, by far. (explain)

GeForce GTX 950M 14624 Mpixels/sec
Radeon HD 6750 11600 Mpixels/sec
Difference: 3024 (26%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
