Radeon HD 8790M 

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.

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.

The GPU features 384 stream processors and a GPU clock of up to 850MHz, which is somewhat faster than what we’ve come to expect from the HD 7000 series.

As expected, the new card delivers rock solid performance, but the early preview might not be the best indication of its potential performance.

If there is one weakness that keeps us as enthusiasts and gamers from getting more excited about Intel's Ultrabooks, it's the graphics situation.

One of the most attractive qualities of AMD's GCN architecture is its alacrity in compute-optimized applications, particularly now that we've seen Nvidia go the other direction with its Kepler design.
