GeForce GTX 650 Ti 2GB vs GeForce GTX 970M

Intro

The GeForce GTX 650 Ti 2GB has a core clock speed of 928 MHz and a GDDR5 memory frequency of 1350 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It features 768 SPUs, 64 TAUs, and 16 ROPs.

Compare that to the GeForce GTX 970M, which features a core clock frequency of 924 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 192-bit bus, and uses a 28 nm design. It is comprised of 1280 SPUs, 80 Texture Address Units, and 48 ROPs.

GeForce GTX 650 Ti 2GB 86400 MB/sec
Difference: 9600 (11%)

Texel Rate

The GeForce GTX 970M is much (more or less 24%) better at texture filtering than the GeForce GTX 650 Ti 2GB. (explain)

GeForce GTX 970M 73920 Mtexels/sec
GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
Difference: 14528 (24%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 970M is a better choice, and very much so. (explain)

GeForce GTX 970M 44352 Mpixels/sec
GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Difference: 29504 (199%)

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 moved past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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