AMD Radeon HD8000M Series Announced, Might Include Rebranded 7000M GPUs

Just ahead of CES 2013, AMD has announced its next wave of mobile GPUs. The HD8000M series¬†will be available in the latest laptops – many of which will be on display at next month’s trade show – and the new-ish components are all based on the latest 28nm manufacturing process.

AMD has revealed some of the specs for the low-end 8500M and 8600M parts, as well as the mid-range 8700M and 8800M parts (see the image above). There’s nothing on the flagship 8900M series just yet, but the details give us a good idea of how these latest parts will stack up against the HD7000M series.

The big news here is that every mobile GPU produced by AMD going forward is based on some sort of GCN (Graphics Core Next) architecture. That means every part is based on a 28nm manufacturing process, which means less heat and less power consumed. Every part will also support Enduro graphics switching (similar to Nvidia’s Optimus technology), and every part uses the new PCI Express 3.0 standard.

These latest mobile GPUs are not based on GCN 2.0, as far as I can tell, and we’ve been told by several sources that the “GCN 2.0″ term has been avoided by AMD in calls. You will likely see GCN 2.0 cards once the 8000 series desktop cards launch in 2013.

There might be a pretty big fly in the ointment, too, as some of these parts appear to be re-branded 7000M series cards — on paper, at least (hence the term “new-ish,” used earlier). The 7900M, 7800M and 7700M GPUs were also 28nm parts, so the differentiation is a bit hazy right now. Based on the preliminary specs, it looks like the “new” 8800M part sits between the 7800M and 7700M, as it has the same number of stream processors as the 7800M (640) with the same estimated clock speed as the 7700M (8800M: 650-700 MHz; 7700M: 675 MHz). Take a look for yourself with this handy dandy HD7000M specs chart (via Engadget):

This is all pure speculation right now, and there’s no knowing for sure until the cards are out in the wild, but rebranding older parts has been done before by both AMD and Nvidia. Game Front will be at CES next month, so this will definitely be hashed out during the show.
