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.

A lot. I think you are very out of touch. No one buys desktops anymore, everyone uses a laptop - and quite a few people want to WOW or COD on them.luniq - Tuesday, June 14, 2011 - link
Agreed. A lot of people I know uses laptop although they rarely need to take it with them and they game too.swaaye - Tuesday, June 14, 2011 - link
I don't think he is. Most computer users don't play games. All they need is a GPU that can run the OS's UI.cotak - Tuesday, June 14, 2011 - link
The sort of people who use laptops and are pushing the CPUs hard are in the reality of the real world a limited bunch. Those who really need the power aren't going to be on a laptop anyhow like you say. Most office staff never use to the full potential of their issued computers even when they were using pentium 4s. And I actually think you'll find a lot of office workers are still humping around a P4 in their laptop bag.This is especially true as a lot of work now a days are done server side. About the only "office workers" who pound their CPU are those with big spread sheets. Even there I do not think you'll find many office workers who'd have an issue with most modern CPUs. They'll just go for a smoke or coffee break while it crunches.
And what review did you read that say there's no advantage in battery life? If you are pushing a game Llano lasts twice as long on the same battery.

Lots of potential, they managed to find a valid niche in Intel's Netbook Hardware Portfolio. I think it's futile to argue about the success of this solution already, as the price will be the determining factor.As I see it, Llano has the potential to bring AMD back in the mobile market on a reasonable scale, but it also has the potential to utterly fail. Since it can't compete in the high-end area in either CPU or GPU performance, it will all depend on the value for your money. If the price is low enough, Llano will fill its niche quite comfortably.
Personally, I will wait for Trinity and Ivy Bridge, as both promise significant improvements and will likely be priced close to their predecessors.

On the one hand, I'm pleasantly surprised that AMD was able to bring the power draw of a K10/10.5 down to those levels, while adding decent GPU. It's a big step up for the to be in the discussion again for laptops. I don't think anyone could have reasonably expected them to go from Danube up to Intel's SB performance level overnight, so from that perspective, it's a big jump for them.On the other hand, it couldn't be more obvious that this product should have been competing against Arrendale about 18 months ago at the price point introduced today. I want to like this product badly, but it's so hard given it's CPU performance. Sure it's great for mid-range mobile gamers, but why would anyone else look at llano? Hopefully AMD can make just as big of a stride with BD-based mobile Fusion within the next 24 months, and then we can perhaps take AMD seriously in the bigger mobile market segments.

Will this mean the lowest common denominator HP $450 laptop of the week the everyone on a budget inevitably buys at retail when they are in a time crunch will suck less?I sure hope so.

I actually like the performance as it seems better balanced than in the dual-core Sandy bridges, ie., about 50% performancethe in single threads apps, 80% in multi-threaded apps and 200% in gaming. IOW better suited towards consumer needs. And battery life is good too.What AMD needs to work on though is lowering the TDP. A8-3500 performance in a 25W enveloppe would allow this to be a good alternative in the upcoming ultrabooks (especially because you can't fit a discrete GPU in those)
Boissez - Tuesday, June 14, 2011 - link
Oh yeah and make all of those APU's compatible with 1600 and 1866 Mhz RAM. RAM speed seems to be a major bottleneck in this platform.ET - Wednesday, June 15, 2011 - link
I think that even lower performance in 25W would be attractive, but it might eat into the E-350 market, unless it's priced significantly higher. I don't think it'd be a big problem for AMD to lower power to that point (certainly for A4), but they're probably waiting to see where the market goes with the current Llano APU's. I believe we'll see a 25W version later this year.
