GeForce GTX 950M vs Radeon HD 6750

Intro

The GeForce GTX 950M features a GPU core speed of 914 MHz, and the 2048 MB of DDR3 memory is set to run at 1000 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 6750, which comes with 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 is made up of 720 SPUs, 36 TAUs, and 16 ROPs.

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

Texel Rate

The GeForce GTX 950M is much (about 40%) more effective 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

The GeForce GTX 950M is much (approximately 26%) more effective at AA than the Radeon HD 6750, and should be able to handle higher screen resolutions without slowing down too much. (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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
