GeForce GT 645M 

The report comes via BenchLife, with the screenshot of GPU-Z showing the higher CUDA core count (though VideoCardz mentions the TMU count should be 128).

Specifications for the upcoming mobile version of NVIDIA's GTX 1070 GPU may have leaked, and according to the report at VideoCardz.com this GTX 1070M will have 2048 CUDA cores; 128 more than the desktop version's 1920 cores.

However the company is also pushing the use of Physically Based Rendering (PBR), a compute-intensive rendering solution that uses far more accurate rendering algorithms to accurately model the physical characteristic of a material, in essence properly capturing how light will interact with that material and reflect off of it rather than using a rough approximation.

However as FP64 compute is not widely used in graphics, this is not something NVIDIA believes will be an issue.

So let’s talk about the GPUs themselves, NVIDIA’s first tier chips would be MXM design which means they would be interchangeable, upgradable and even offer SLI support on some notebook designs.

Next up, we have the entry level models which will feature the onboard design which mean that these GPUs will be permanently soldered to the mainboard hence no upgrading can be possible.

AMD’s Kaveri APUs would feature the latest core architecture along with enhanced GCN graphics on a single die package.

This means that higher frequency DDR3 memory just might come in handy with Kaveri APUs to unleash the full potential of the graphics core.
