These chips are still based on Kepler (600-series), but feature more CUDA cores, more memory, a wider memory bus, and faster clockspeeds.

It will work at 823MHz+ GPU clock and feasture 4GB of GDDR5 memory clocked at 5GHz and paired up with a 256-bit memory interface that add up to 160GB/s of memory bandwidth.

AMD Reveals First Mobile Radeon M200 Parts & Rebadges

by Ryan Smith |
www.anandtech.com
In recent years this has especially been the case for laptop/mobile graphics thanks to the larger volume and higher levels of integration as found on those parts, though this does have the unfortunate side effect of meaning GPU announcements get caught up in the deluge of announcements coming out of CES.
Moving on to our second confirmed product, we have a new low end SKU called the R5 M230.
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.
Richland is approaching 60 fps in our Sleeping Dogs benchmark at medium quality, definitely not bad at all.
I never spent a ton of time testing memory overclocking with Trinity, but my A10-5800K sample had no issues running at DDR3-2133 either.
The GTX 780M is not quite the mobile equivalent to the desktop GTX 680, but NVIDIA is matching it up against AMD's 8970M GPU and claims that it can run games like Sleeping Dogs, Assassins Creed 3, and Borderlands 2 at Ultra settings (1080p).
NVIDIA is now adding higher-end mobile GPUs to the 700M family with the GTX 760M, GTX 765M, GTX 770M, and GTX 780M.
