In The News From around the web

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.

Nvidia announces five new Geforce 700M GPUs

by Slobodan Simic |
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.

Sapphire mITX and a Budget Tahiti GPU

by Jarred Walton |
Sapphire calls their card the HD 7870 XT, but it’s important to note that this is still a full Tahiti GPU in other areas and it should easily outperform the HD 7800 Pitcairn offerings (which max out at 1280 cores clocked at up to 1000MHz stock).
Like most graphics companies, Sapphire didn’t have anything major to announce at CES.
