GeForce GTX 750 vs GeForce GTX 970M

Intro

The GeForce GTX 750 uses a 28 nm design. nVidia has clocked the core speed at 1020 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this model. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

Compare all of that to the GeForce GTX 970M, which features core clock speeds of 924 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1280 SPUs along with 80 TAUs and 48 ROPs.

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

Texel Rate

The GeForce GTX 970M should 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

The GeForce GTX 970M should be quite a bit (approximately 172%) faster with regards to full screen anti-aliasing than the GeForce GTX 750, and will be able to handle higher screen resolutions better. (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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
