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.

Civ5 and TWS2 are both tested with the latest drivers. The K53E was also tested with drivers that are at most a couple months old. Intel current lists the latest laptop drivers as 15.22.1.64.2361 from 4/13/2011, which is what I'm running on the Intel units right now. If there are some newer drivers that I'm missing out on, let me know and I'll go try them.duploxxx - Tuesday, June 14, 2011 - link
Nice review, it seems like there is a lot of work on CF.Actually I reviewed the Liano already months ago, I mentioned in the last mobile reviews that it will be better performing then the Toshiba with the P920 with really good battery performance. So it is a win -win for the budget line anyhow. Top line remains intel for the CPU power.
Regarding the quote:
Now if you want to have your cake and eat it too, the APU to wait for would be Trinity. Due out somewhere in the 2012 - 2013 timeframe, combine a Bulldozer derived architecture with AMD's next-generation GPU architecture and you've got Trinity.
Trinity will not only be an improved GPU it also has the BD core inthere which will offer much more punch. THe reason LIano is late is because of the 32NM process. It could have been released much sooner. Sure they took an outdated K10 and that is the main issue together with the not enough aggressive Turbo for single thread, they should have adapted this more aka BD.
But assumin Trinity is a rather late 2012 project (by stating 2012-2013) you are way way off...

Quote probably reflects an increase in pessimism due to recent events. Bulldozer is still not out, and AMD is said to have had a hard time getting clocks up. So sure, we're all hoping to see Trinity early in 2012, but anyone setting their expectations a little farther are less likely to be disappointed.duploxxx - Wednesday, June 15, 2011 - link
didn't i mentioned it would be launch faster then expected?http://www.cpuforever.com/showthread.php?tid=1574&...
the delay of Zambezi BD has nothing to do with real architecture issues.....

That's not the sites which posted on it, including Anandtech, said based on what AMD said (that is, that Bulldozer was not up to speed).Jamahl - Tuesday, June 14, 2011 - link
Was that really needed? I mean...really? Who the hell would do that and for what reason?ET - Tuesday, June 14, 2011 - link
I already got my E-350 laptop, but as Jarred says, Brazos just became less interesting. I'll be waiting to see what price point and performance the dual core Llano will have. What impressed me most was battery life, which is competitive with the E-350 laptop, and it'd be interesting to see how small and light Llano laptops will get.The other takeaway I have from this is that as usual I'm impressed at how far Intel has gone with its integrated graphics. Sure Llano gives it a good beating, but that's at the expense of a lot more die space. I imagine that Intel will continue to tweak its 3D cores and I can't wait to see how this race will develop.

What happened to power consumption?!Some of us get laptops due to the optimization in the power department over similar desktop parts!
JarredWalton - Tuesday, June 14, 2011 - link
Power = [Battery Capacity] / .98 [efficiency] / ([Battery life in minutes] / 60)So if you take the battery life charts, you can determine roughly what the total system power draw is using the above. Or you can look at the "Relative Battery Life" charts and get the same information as Minutes/Wh instead of converting into Watts.

In my work I get a lot of laptops to fix. If there is one game or genre that appears on 80% or more of them its......The Sims.
I also get asked a lot "if I buy this laptop will it play The Sims?"
Never ever been asked if a laptop will play Crysis or any of the games you use.
Just saying.
