GeForce GTX 750 vs GeForce GTX 970M

Intro

The GeForce GTX 750 comes with a GPU clock speed of 1020 MHz, and the 1024 MB of GDDR5 memory is set to run at 1250 MHz through a 128-bit bus. It also is made up of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare all of that to the GeForce GTX 970M, which uses a 28 nm design. nVidia has set the core frequency at 924 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific card. It features 1280 SPUs as well as 80 TAUs and 48 ROPs.

In theory, the GeForce GTX 970M should be 20% quicker than the GeForce GTX 750 overall, because of its greater bandwidth. (explain)

GeForce GTX 970M 96000 MB/sec
GeForce GTX 750 80000 MB/sec
Difference: 16000 (20%)

Texel Rate

The GeForce GTX 970M will be a lot (about 126%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

GeForce GTX 970M 73920 Mtexels/sec
GeForce GTX 750 32640 Mtexels/sec
Difference: 41280 (126%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 970M is the winner, and very much so. (explain)

GeForce GTX 970M 44352 Mpixels/sec
GeForce GTX 750 16320 Mpixels/sec
Difference: 28032 (172%)

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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
