    "I met up with Imagination Technologies, makers of the PowerVR SGX graphics core that’s used in Intel’s Poulsbo chipset - the ideal companion for the Atom processor. Most netbooks to date have shipped with Intel’s 945G chipset, but we’re finally starting to see models come out with Poulsbo. The biggest advantages to Poulsbo are much lower power consumption as well as hardware video decode acceleration for all of the major codecs (MPEG-2, VC-1, H.264).

    I got a quick demo of a Dell Inspiron Mini 12 decoding a 1080p H.264 Blu-ray rip (20 - 35Mbps) while running through a Quake III timedemo. The video clip didn’t drop any frames and the Quake III demo ran at above 30 fps. The engineers on hand indicated that a real concern in these sorts of situations isn’t the GPU horsepower, the PowerVR SGX core can easily handle the two tasks, but rather memory bandwidth. Poulsbo only supports a single channel of DDR2-533 memory, barely enough bandwidth by today’s standards.

    The Imagination Technologies staff also ran a dual stream video decode demo where they had a Atom/Poulsbo netbook playing one 8Mbps H.264 video and a 1080p H.264 video on an external display, simultaneously. Again, memory bandwidth is the only limitation here - the Atom never peaked above 29% CPU utilization."

    EDIT: If this was true, then the HD limitations on the Poulsbo chipset is a software/driver issue, not hardware. Furthermore, if this potential was achieved, then Ion would be obsolete - the Poulsbo uses far less power than the 945GSE, which itself uses far less power than Nvidia's Ion.

    BTW, it's the weirdest thing...it seems the 6 cell battery option is available for the Mini 10 on Dell's Canada website. It has more than twice the capacity (56Whr vs. 24Whr), suggesting that it may be using higher capacity cells similar to the Asus 1000HE.

    It's a $50 (CAN) upgrade.

    I was going to get a Mini 9 as they are in the UK outlet store, but l might wait for the Mini 10/12's to start appeariing there.
