Netbooks aren't dead, but they're not quite the hip topic of discussion they were a few years ago. The focus on cost conscious computing hasn't changed since the introduction of the first netbook, but the maturity of tablets has. Intel still sees the netbook segment as a profitable one (for itself) through 2012, although I'm fully expecting the line between netbook and convertible tablet to blur after the launch of Windows 8. 

Atom has been at the heart of nearly all netbooks since the segment's inception. We've seen only one major platform shift since then: from the original 2008 Atom platform to Pine Trail. Pine Trail integrated the GPU and memory controller without significantly changing the Atom architecture. Today Intel is officially announcing its next major netbook platform shift: Cedar Trail.

While the original Atom and Pineview (Pine Trail's Atom) were built on Intel's 45nm process, Cedar Trail moves to 32nm. Cedar Trail's SoC shrinks to 56mm2, finally making it smaller than AMD's Zacate APU. The underlying CPU architecture hasn't really changed, nor have cache sizes (512KB L2 per core) or clock speeds (1.66GHz and 1.86GHz parts available), so what this is really about is a reduction in power consumption. 

There are three Atom CPUs being offered as a part of Cedar Trail: the N2600, N2800 and D2700. Just as before, the N-series are for netbooks while the D-series are for desktops. All of the Cedar Trail Atoms are dual-core parts, but they all slot into the same power envelope as the old single-core Pine Trial platforms (5 - 8W). The only exception is the D2700 which is a 10W platform. Note that this is the total TDP for the Atom SoC + the NM10 Express chipset (providing USB, LAN, PCIe, etc...). 

The spec breakdown is below:

Given the same number of cores and the same clock speeds, CPU performance shouldn't go up compared to Pine Trail. Since everything is now dual-core we should see a boost at the low end, but I wouldn't expect to see CPU performance that's better than Zacate

Cedar Trail now supports DDR3-800 and 1066 (up from 667MHz max data rates before). The bigger change is the GPU. The GMA 3150 used in Pine Trail was an Intel Gen graphics derivative (45nm GMA 3100), however Cedar Trail now features a PowerVR SGX 545 sourced from Imagination Technologies. At 640MHz in the N2800, we've never seen the SGX 545 run at anywhere near this clock speed before so it'll be interesting to see how well it performs. Intel is claiming a > 2x GPU performance improvement compared to the GMA 3150 in Pine Trail in 3DMark 06. The big question is Windows driver maturity, but we'll find out soon enough as systems based on Cedar Trail are in production now and are expected to ship in early 2012. Expect to see Cedar Trail netbooks from ASUS, Acer, HP, Lenovo, Samsung and Toshiba for starters.

The new graphics block also includes support for H.264 video decode acceleration (we're still digging for specifics) as well as Intel Wireless Display technology. Note that WiDi support will vary depending on the system and price point:

Intel is expecting the vast majority of Cedar Trail netbooks to be sold in the $199 - $229 price point. At $299 is where you'll likely find features like WiDi as well as potentially fanless designs. Don't expect any of those new form factors at $399 until the later part of next year, likely coinciding with Windows 8's release.

Overall the addition of HD video decode support and lower power consumption are both nice features to have, but I'm skeptical as to whether this will be enough to carry Intel based netbooks throughout the majority of 2012. Atom is in dire need of an architecture update (something we'll get in 2013) and the netbook as a platform is in need of a refresh. I do hope to see some manufacturers taking risks with slim, fanless Cedar Trail based designs next year but we'll have to wait and see if they're any good.

    So now that Atom is going all out PowerVR - which is very nice from a perf per watt point of view - but where does this leave open source support? Linux on PowerVR is a miserable experience. The bleeding edge is more or less at the svga-level (when it happens to work), and even that hasn't really reached any distro release yet.

    I suspect any decent level of acceleration will be limited to closed firmwares/platforms, as it is today.

    The SGX 545 is capable of DX10.1, but is probably listed as DX9 due to driver issues.

    These Atoms will take a lot less power than the AMD solution, and one is even designed for fanless systems, so I think they could be interesting solutions. We'll have to wait and see. There's also the price aspect, and looks like Intel is aiming lower than where AMD currently sits.

    When intel launched it it was at 45nm, and is listed in their ark database as a 2.1W part; but the tables above are implying it as only 1.5W (5/8W total, 3.5/6.5W for the CPU). Either way it's a rather large chunk of the total, and dropping to 32nm should chop a decent chunk off the total allowing for either longer battery life or marginally higher processor clocks. (1.73 and 2.0 ghz mobile?)

    The new high speed wifi "WiGig" routers from Orbital use this processor in their low end routers the Phantom and the Spitfire. FOr the high end they even use core I3's
    Their 802.11ad draft goes to 10G/sec wireless with these chips and can stream up to 2 movies simultaneously to different screens over the WiFi

    Not sure though which type of Cedar Trail they are integrating?

    you can see them here;

    Vast majority of the commentators seem to miss the goodies in new Atom:

    - low TDP allowing fanless constructions (that's something new!)

    - excellent power efficiency, hence superior battery time

    - price, price, price hence cheap, cheap, cheap products

    Pitting the new Atom against AMD's E-series processors is like pitting E-series against Sandy Bridge i3-processors.

    The new Atom is in class of it's own, there is no product to compare with. It is untouchable in the low end netbooks for now.

    I shall warn users of the N2600 about x64 Windows support or I should say, the lack of it. The platform would be perfect for MS Home Server 2011... if Intel cares to support it. I don't need to increase memory, just to install the software which is impossible at this time. The alternative is to run a x86 version of Win 7 or, if the target software would allow, Linux. The excuse from Intel is that they are too busy with Win 8....
    Go figure...
    By the way, board is a Jetway NF9C-N2600 with a crippled BIOS for x64, since some of the drivers from Intel are thin.

    ...and see what the OS difference does for the performance of both the Atoms AND AMDs. Of course, beta is beta, but I have doubled my battery and there are half the processes running at any time with the same program loadout and similar registry.

    Maybe Intel is waiting for the OS. I think that, at 3200, if you could get a cheap touchscreen into a convertible, I have a feeling that, while it won't actually scream, you won't notice nearly as much of a decline in performance...except for that sticky 1080p thing....
