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.

The 760M and 765M both use 768 CUDA cores, but the 765M is clocked almost 200MHz faster.
The RAM and core are connected via a 256-bit interface.

It is not clear how GT 740M ends up clocked higher than the GT 745M but it might have something to do with the maximum Boost.
All five new GPUs will feature Nvidia GPU Boost 2.0, Optimus and Nvidia Geforce Experience technologies.

Boost Clock allows the GPU to turbo up to a higher clockspeed so long as the GPU is under its power and temperature limits, allowing AMD to scrape every bit of thermal headroom from their GPUs.
All of these GPUs are based on the Heathrow GPU (desktop name: Cape Verde), packing 640 Stream Processors along with 40 texture units and 16 ROPs.
