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.

I disagree emphatically. Having used Atom-based and E-350-based netbooks (and let's not kid ourselves, the E-350 is a netbook chip), the E-350 machines just feel snappier. I'd never buy an Atom-based computer, but I love the E-350.ppeterka - Tuesday, June 14, 2011 - link
Absolutely agree with Dustin... Recently bought an E-350 to replace my wife's painfully struggling Atom n455 netbook. The user experience went through the roof. My wife is happier than ever (and that's a very good thing, and a very good benchmark! :))) )She is a "not-professional-but-quite-demanding" user. (20-30 browser tabs, Office, and video streaming at once, Twitter with multiple accounts, and so on). She used to have a C2D T6600 + GeForce 310 (or 210 , don't exactly remember) Toshiba notebook too, but since we acquired the Brazos one, she didn't turn the old one on. Have to sell it now...
I know, Brazos is weak if compared to anything other than Atom. But magically it manages to absolutely fill its role. Hats off to AMD on that one!

I wouldn't describe your wife as a "quite demanding" user.Browser tabs don't take up CPU cycles once loaded (unless the page uses AJAX, and even then a simple http request isn't a daunting task even for a 20 year old processor) and only uses a little bit of memory.
I'd call MS Office pretty basic computer usage .
today video decoding is almost always hardware accelerated, so most of the work is offloaded onto the GPU (where E-350 has the upper hand).
but I digress.
just look at the benchmarks, there isn't much of a difference between the E-350 and a D525 (or similar) in CPU intensive tasks...
any percieved "snappiness" on your part is down to other aspects of the system (such as HDD for instance).

are you forgetting single-threaded results?Broheim - Wednesday, June 15, 2011 - link
1 synthetic benchmark... big whoop.they are equal in everything else
duploxxx - Friday, June 17, 2011 - link
perhaps actually read some reviews, they all agree on one thing, the system feels much smoother for daily tasks. I am sure you don't have both or used both so have no idea what you are talking about. just launching OS or any application is enough to notice the difference. I owned a n570 so i do know.Broheim - Monday, June 27, 2011 - link
that is subjective opinion and the only subjective opinion that matters to me is my own. You fail to realize that the perceived user experience is a product of the system as a whole and not just a single component....sinigami - Wednesday, June 15, 2011 - link
i've only gotten to run two single threaded benchmarks on the E-350, and out of those two, the bench that showed the biggest improvement over the Atom was CPUMark99, by 6% percent, over an N455 in an MSI netbook.Granted, i didn't get to run all four of my single-threaded benchmarks on the E350 against the N455, but i will, and soon.

Atom N455 is single core.There are new and better Atoms like N550
sinigami - Wednesday, June 15, 2011 - link
and, BTW, the N455 even plays 720p MKV. Who would expect any more than that out of a $250 netbook?But at the price of the E-350, i do expect more. And by more, i mean more than just ION level graphics that might let you send out 1080p to an external display. I want some significant CPU horsepower.
