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.

So, what do you tell them? The only benchmarks of The Sims 3 I could find are pretty old and didn't offer much detail, but I think based on them that high quality would require more than the lowest IGP. (Then again, normal or low quality should probably run fine on anything.)msroadkill612 - Tuesday, August 2, 2011 - link
ta 4 the post - but dont salesmen have a duty to sell them a bit of insurance against the next game fadash9 - Tuesday, June 14, 2011 - link
Bring on the OpenCL apps, excuse me applications- Excel rewritten to take advantage of heterogeneous computing would silence everyone about Star CPU cores. The ball is in the hands of the people (to buy them), then the software developers (to program for them) - that's why Star cores? APU apps neededmsroadkill612 - Tuesday, August 2, 2011 - link
I think it will happen. Big mobs will identify niches that can profit from OGPL & profit from using it - open languages always win in the end.I see fusion server apuS in the future.

What a terrible CPU, who would want something that performs like a Phenom in a new computer circa 2011. The future might be fusion AMD, but you sure as heck aren't part of the future anymore.jabber - Tuesday, June 14, 2011 - link
90% of laptop owners wouldnt know if they were using a Brazos or an i5 in their laptops.The only real differential is in transcoding, ripping etc. and very few folks in the real world actually do that. Especially on laptops.
Price is far more important than outright performance. Has been for some time now.

False. My gf doesn't know anything about computers. But she somehow knew that Intel makes the best mobile CPUs even before asking me what to get. Clearly Intel marketing > AMD's. All of my current friends who just bought a computer all went with i3/i5/i7 processors only because they "heard" Sandy Bridge is the fastest CPU around.Llano is nothing more than a Phenom with a faster GPU. Phenom already didn't sell well against C2D/C2Q/Core i7 (1st) gen and isn't getting any better against SB. The only way AMD is gaining market share is if they ship cheap laptops with Llano to users for whom the price of a laptop is the most important factor.

Well, you have pretty computer literate friends. Most people I know would have no idea what Sandy Bridge is, probably not even what i3 and i5 are, and would only buy i3 or i5 because: a) AMD had very little market presence until now; b) I'd recommend them. That said, most of the people I know have no idea that AMD exists and is making CPU's (I mention it occasionally, and they're always surprised, so I guess it doesn't register), so it does look like AMD's marketing is pretty crappy.That said, I think that your analysis of why Llano will fail isn't right. For most people the CPU power really doesn't matter that much. They'd have no idea if i3 or Llano is better, and most likely won't be able to tell the difference in practice (unless they run a game for which the HD 3000 is unsuited). Sure Llano is for the low end market, but that's where most sales are, and it's certainly much improved in terms of power usage, which is an important enough measure to help it gain market share.

You are probably right that most people won't tell the difference between a Llano or an i3/i5/i7. But to them the perception of knowing that they have a slower CPU is what matters. One of my friends was building a PC for browsing the net only. I told him he'd be perfectly fine with a $100 CPU but he insisted that the system must have Sandy Bridge because it's the latest modern CPU. I gave up trying to convince him that his internet browsing experience will be more limited by his ISP latency and speed rather than CPU performance.So as long as AMD convinces the average consumer that Llano is at at least as good, they will do well. The problem is AMD's marketing department is worse than a 1st year undergrad student studying marketing in business school. They think if they pay millions of dollars to put AMD on F1 cars, people will notice?
You made a very important point - a lot of people don't even know what AMD is or that there is another competitor to Intel. Imagine if GM, Ford or Chrysler made cars that were more reliable than Honda or Toyota. It would still be a while until the average consumer would abandon the Japanese brands since the perception of reliability would lag behind reality. AMD has this similar problem with their CPU brands, which only marketing can fix.

Really... that's rather unimpressive.The GPU of Llano beats intels HD-graphics in games, what a surprise. But how many people do I know personally, that play games on their laptops anyways? Laptops are primarily used as mobile office-computers and they do still rely more on CPU-performance.
From all the experience I've made the HD3000 graphics of mobile SNB CPUs are perfectly fine for all tasks I throw at them (excluding games). So the question is, why would I buy a Llano-based laptop instead of a SandyBridge one?
Llano doesn't offer better battery-life so the only reason might be the price, but with i5-2xxx laptops starting at $600 I really don't see alot of competition there for intel, if we're talking anything else then gaming.
