The AMD Llano Notebook Review: Competing in the Mobile Market
by Jarred Walton & Anand Lal Shimpi on June 14, 2011 12:01 AM ESTAMD’s Llano Mobile Test Platform
Similar to our Sandy Bridge Notebook, AMD shipped us a test notebook that likely will not actually hit the market. It’s also early hardware, as we haven’t received anything from the usual suspects, but performance and battery life should be representative of what we’ll see in shipping hardware. There’s still room for BIOS, firmware, and driver optimizations, so if anything we’d expect some scores to even improve from what we’re reporting, but for now we can get a starting point for what to expect from shipping Llano laptops and notebooks. Our test notebook is manufactured by Compal, and we understand there was a very limited production run, so what we’ve got is an existing shell with a new motherboard, slapped together for preview articles. Here are the specifications of our test system.

AMD equipped this laptop with their highest performance 35W part, the A8-3500M. That gives us four cores running at a nominal 1.5GHz, all 400 Radeon Cores clocked at 444MHz, and the potential for Turbo Core to take the CPU has high as 2.4GHz. Here’s where we run into our first snag, unfortunately: apparently there’s no software currently available that will report the actual real-time core speeds for the CPU or GPU. Turbo Core appears to be working in some cases, but we don’t know how fast the CPU cores are running. We’ll see the results in the benchmarks in a moment, but for now it appears that the Llano Turbo Core isn’t quite as aggressive as Sandy Bridge’s Turbo Boost.
One interesting aspect of the test notebook is that it comes equipped with both the integrated Fusion GPU (fGPU) along with an HD 6630M discrete GPU (dGPU). The 6630M is a Turks core with 480 Radeon cores clocked at 485MHz (well, this GPU is clocked at 485; the specs for 6630M are actually 500MHz), with 1GB of DDR3-800 memory. We'll see what happens when we enable Dual Radeon later.
The rest of the notebook specs are pretty much what you’d expect. The hard drive is a 250GB 7200RPM model from Hitachi, so performance won’t be quite as good as the latest 500GB+ models and it won’t come anywhere near SSD levels. Networking is present and accounted for, with both Gigabit Ethernet and 2.4GHz 802.11n WiFi. The optical drive is Blu-ray capable (despite the DVDRW face plate in the pictures), and there’s even a USB 3.0 port.
We could discuss the build quality, keyboard, and screen quality, but there’s no real point in doing so on a laptop that won’t see full production. The keyboard is the “floating island” style commonly seen in Acer builds, which Compal apparently manufactures, and the LCD is a matte panel for a change (but still low contrast). The overall build quality isn’t bad, but we expect to see better retail builds from Acer, ASUS, HP, Lenovo, and others so we won’t spend any more time discussing the specifics of this laptop other than to note that it has a reasonable 58Wh battery and a 14” LCD. Expected pricing is $500 for laptops with A4 APUs, $600 for A6 APUs, and $700+ for the A8 series. Adding a discrete GPU like the 6630M (and thus enabling Asymmetrical CrossFire) should tack on another ~$100.
AMD is quoting “over eight hours” of battery life, but that’s highly dependent on what you’re doing as well as battery capacity. Since that’s going to be one of the major improvements with Llano, we’re going to start there.

Can you try setting the affinity manually so that it has to use only one core? I notice that even though I'm running only one thread, that thread will jump around to all my available cores, making them all look like they are running at 25%. Maybe by the time AMD's turbo kicks in, the thread is already moved to another core.GullLars - Tuesday, June 14, 2011 - link
Looking forward to the re-test with an SSD.IMHO all machines over $600 meant for general purpose use in 2011 should include at least a 32GB SSD of Indilinx Barefoot performance or better.
My laptop from 2007 with 2,2GHz C2D and a 32GB Vertex (retrofitted in 2009) still wipes the floor with new $800+ laptops with HDD-only for general use.

Having played with a bunch of laptops using 64GB SSDs, they all feel snappier, though of course it doesn't help with gaming frame rates or CPU computations. Still, I have to say that 64GB isn't big enough for me. If you can get a 32GB mSATA SSD and some sort of SSD caching, and then have a main 500GB HDD, that would be the sweet spot. If you're going SSD-only, I need at least 120GB, and for anything that can run games I'd want 240GB. (By the time I install most of the games I'm currently interested in playing on a regular basis, I easily fill up a 120GB drive.)Anyway, I'm swapping in the SSD now and will start testing during the week, with the follow-up article hopefully ready next week. I've got DC SNB, Arrandale, DC Phenom II, E-350, and now Llano for the article. Anything else you want to request before I call it quits? I've still got the XPS L502x and an AMD K625, but I figure the five laptops are a reasonable representation of what's currently out there. (Note that I have currently focused only on IGP equipped laptops.)

Results with/without DDR3 RAM would be interesting as it seems RAM speed is a bottleneck.Boissez - Tuesday, June 14, 2011 - link
dang... That should have been with/without DDR3 1600 Mhz RAMBrian23 - Tuesday, June 14, 2011 - link
Application compile benchmarks. ;-)Cloudie - Tuesday, June 14, 2011 - link
The battery life has exceeded my expectations although battery life is a low priority for me when buying a laptop. As long as it gets 4 hours or so at idle is fine by me.Both the GPU and CPU performance has disappointed me somewhat but on the plus side I was not aware until now that the APU being tested was a 35W version, I simply assumed it was the fastest 45W one. Hopefully the CPU perfomance will be just that little bit better on the 45W APUs. And OEMs better get out some decent compact systems with this in... I'd say 13-14" chassis will do me just fine.

If they can get this priced out in a $600 laptop with all the bells and whistles... It will sell. Looking locally (and online) decent gaming laptops start out at about $800. Looking at the numbers it's more then acceptable I think. Profit has to be in there though for AMD.. If their not turning an acceptable profit on each chip then... it will be a wash.duploxxx - Wednesday, June 15, 2011 - link
Looking at the recent preview of anandtech on the desktop Liano part and the increased performance from DDR1333 to DDR 1866 i would like to see what it would bring on a Mobile platform. Afterall LIano mobile does support ddr 1600http://www.anandtech.com/show/4448/amd-llano-deskt...

1600 MHz DDR3 - lets make this accurate, since Llano can utilize it.Thank you.
