AMD's Radeon 7000 series GPUs have officially been out for, what, just over four months now? Time sure flies! But even though you've been able to shove next-gen Radeon cards into a desktop build for over a third of a year, laptop users haven't been quite as lucky, as mobile variants hadn't been announced -- until today. This morning, AMD announced the Radeon 7000M series with three new GPUs built around the 28nm manufacturing process.
The chart above lays out most of the pertinent specs for the enthusiast-grade 7900M ("Wimbledon"), the mainstream 7800M ("Heathrow") and the Ultrabook-friendly 7700M ("Chelsea"), the new 28nm GPUs. The other entries in the 7000M lineup are based off the older 40nm process.
TheVerge reports the flagship 7970M hits 70fps in Skyrim at 1920x1200 resolution, blowing away the 49.3fps put up by the Nvidia 675M. Keep in mind, however, that the 675M is basically a rebranded 580M and isn't based on the Kepler architecture. The 7870M and 7770M hit 41.4fps and 36.9fps, respectively. AMD claims the mobile GPUs are powerful enough to run up to six monitors using Eyefinity.
Energy efficiency is oh-so-important in this slim-and-light notebook days; the 7000M series lays off the juice thanks to AMD's new "Enduro" switching technology, which behaves like Nvidia's Optimus technology and swaps the graphical load between integrated and discrete graphics depending on need. Radeon 7000M series cards can also shut down unused portions of the GPU to save even more energy and disable the GPU entirely when integrated graphics processors are handling the workload.
