What you see here is an Intel Core i7-3770K processor, a Gigabyte Z77X-UD3H motherboard, four gigs of AMD memory, AMDвЂ™s MXM adapter, and our two mobile Radeons.

Using this setup, weвЂ™re able to test mobile GPUs free from the confines of notebooks or proprietary qualification hardware. For our test platform, AMD sent us an MXM to PCI Express x16 adapter alongside an off-the-shelf desktop processor, motherboard, and memory. AMD supplied the aforementioned GPUs-the Radeon HD 8790M and 7690M-as bare MXM modules, each one with its own, dedicated cooler. With the help of AMD, weвЂ™ve tried a different approach this time. That can make comparisons with other offerings tricky, especially when you want to benchmark a previous-gen part that may only be available inside older systems with outdated CPUs. Traditionally, testing mobile GPUs involves using pre-assembled laptops. Since we have the latter two GPUs our disposal, weвЂ™re going to put that assumption to the test. AMDвЂ™s internal benchmarks show an increase of 20-50% from the 7670M to the 8770M, and one would expect the 7690M to trail the 8790M by a similar margin.

The new architecture and higher clocks bode well for performance, despite the 8790MвЂ™s lower ALU count. No new features have been added, either, beyond those that were already present in proper, GCN-powered 7000M-series parts.

Interestingly, AMD tells us itвЂ™s made no refinements to the GCN architecture in the Radeon HD 8000M series. Also, of course, the 8790M is based on AMDвЂ™s latest GPU architecture. The 8790M has fewer shader ALUs than its predecessor, but at least in our test sample, its clock speeds are higher-and it comes packed with more memory. What little weвЂ™ve been able to glean about our test samples is listed in the table below: GPU

WeвЂ™d love to compare transistor counts at this point, but unfortunately, AMD is refusing to disclose complete specifications for the Radeon HD 8000M series until January 7. That difference is at least partly due to the fact that Mars is built using the finer 28-nm process, so its transistors are smaller. Mars measures about 77 mmВІ by our count, while Thames takes up 118 mmВІ. Right: the new Radeon HD 8790M.ДЄ cursory look at the picture above shows that the 8790MвЂ™s graphics chip, code-named Mars, is quite a bit smaller than Thames, the 40-nm slab of silicon that powers the 7690M. As luck would have it, we have representatives of both lineups in our labs today: a 7690M and an 8790M. As we reported a few days ago, AMD has rejiggered its mobile branding somewhat, so the Radeon HD 8700M series is meant to succeed the Radeon HD 7600M series. WeвЂ™ve been able to get one of those newcomers, the Radeon HD 8790M, in our lab today. All of them are based on the GCN architecture and built using TSMCвЂ™s 28-nm fab process, and AMD promises some meaty performance gains over the 40-nm TeraScale parts theyвЂ™re supposed to replace. AMD officially announced the first members of the Radeon HD 8000M series earlier this week, and those offerings are due out early next year. However, cheaper and thinner gaming notebooks have essentially been stuck with re-branded last-gen Radeons for the better part of a year. Those offerings were built using TSMCвЂ™s 40-nm fab process, as well, instead of the finer 28-nm process used to fab newer, GCN-powered chips.ДЄMD did eventually introduce GCN-driven Radeon HD 7700M, 7800M, and 7900M series products to service the higher end of the mobile market. The company decided to use its older TeraScale architecture to power mid-range and low-end members of the Radeon HD 7000M series, from the 7600M on down. When AMD got around to updating its mobile offerings, though, it did something a little disappointing. Before long, GCN had spread through much of AMDвЂ™s desktop graphics lineup, providing fierce opposition to the competition from Nvidia. The architecture brought with it a slew of improvements, which we covered at length here. AMDвЂ™s Graphics Core Next architecture premiered around this time last year on the Radeon HD 7000 series.
