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.

It may be impossible to know the exact speed the cores run, but it would be interesting to run a test to get some relative numbers.You can run a single threaded CPU bound program such as SuperPI, then run it again with the other three cores at 100% (for example by having another three instances of SuperPI running). Do this on AC and battery, and it might generate some interesting numbers. At the very least we'll be able to tell whether the 1.5GHz -> 2.4GHz ratio looks right.

By the way, I just read Tom's Hardware review, which was unique in that it compared to a Phenom II X4 running at 1.5GHz and 2.4GHz. It looked from these benchmarks like the A8-3500M is always performing around the 1.5GHz level of the Phenom II X4 (sometimes it's a little faster, sometimes a little slower), which suggests that Turbo Core doesn't really kick in.i_am_the_avenger - Wednesday, June 15, 2011 - link
Maybe this will cheer the AMD Fans a bitThis article did not mention some nifty features the APUs have (or maybe it did I did not read it line by line)...................................
Watch the video below from engadget:
http://www.engadget.com/2011/06/13/amds-fusion-a-s...
It shows how these APUs can smooth out shaking videos real time, even while streaming from Youtube! and it does a very good job.
Another feature is how it en-chances videos (colour etc.)
This improves general user PC experience.......... something very desirable
The video also shows how AMD wants to target general users and not work enthusiasts
Another video shows comparison between the i7-2630QM and A8-3500M while multitasking video related applications.
http://www.engadget.com/2011/03/01/amd-compares-up...
---Interesting to note that the APU Gradually increased its power consumption while i7 was like bursting to and fro, something the way turbo core acts maybe-----
I think it is work vs general performance,
Intel's great for work, when you need to finish tasks and it needs to be done quickly,
while AMD APUs give you a good over all pc and multimedia performance - you watch videos, play games, so what if the zip file extracts a minute late and the fGPU performance is great....
You may buy a i7 SNB with discreate GPU but that has a battery life hit (for same battery capacity) and also extra heat generation which requires more fans, also the extra weight..
Please don't start judging me or something....
I am getting confused myself, while intel looks great in every way except stock gaming and battery life(not that bad)... I think I don't need that much power, even if I work - my work isn't so CPU oriented that an i7 would matter, a 30 second task finishes in 20 ok but it does not matter to me..... but improved video and battery seems more useful to me
I don't think that all of us have to tax our CPUs to full potential -- a few have to, not considering them -- so even if Intel have faster processors for many it does not affect them as much.

For all your moaning about not getting Asymmetric CrossFire to work, you didn't read the reviewers guide that says it only works in DX10 and DX11 mode, not DX9. So your Dirt2 benches for example clearly state DX9 for this test. I don't know about the other titles on that page - you say 5 of the others are DX9 titles. Do these titles have DX10 modes of operation - if so, USE THEM.Otherwise it just looks like you are trying to get the best results for the Intel Integrated Graphics.
Just put "0 - Unsupported" for DX11 tests by HD3000 like other sites have done.

The article said:"AMD told us in an email on Monday (after all of our testing was already complete) that the current ACF implementation on our test notebook and with the test drivers only works on DX10/11 games. It's not clear if this will be the intention for future ACF enabled laptops or if this is specific to our review sample. Even at our "High" settings, five of our ten titles are DX9 games (DiRT 2, L4D2, Mafia II, Mass Effect 2, and StarCraft II--lots of twos in there, I know!), so they shouldn't show any improvement...and they don't. Actually, the five DX9 games even show reduced performance relative to the dGPU, so not only does ACF not help but it hinders. That's the bad news. The only good news is that the other half of the games show moderate performance increases over the dGPU."
I agree that at least in the case of DiRT 2 that's blatantly false, since that game was one of the first to use DX11, and was given with many Radeon 58x0 cards for this reason.
JarredWalton - Friday, June 17, 2011 - link
DiRT 2 supports DX11, but it's only DX9 or DX11. We chose to standardize on DX9 for our Low/Med/High settings -- and actually, DX11 runs slower at the High settings than DX9 does (though perhaps it looks slightly better). Anyway, we do test DiRT 2 with DX11 for our "Ultra" settings, but Llano isn't fast enough to handle 1080p with 4xAA and DX11. So to be clear, I'm not saying DiRT 2 isn't DX11; I'm saying that the settings we standardized on over a year ago are not DX11.jitttaaa - Wednesday, June 15, 2011 - link
How is the notebook llano performing as good, if not better than the desktop llano?ET - Wednesday, June 15, 2011 - link
At least as far as CPU power is concerned, the desktop part is obviously faster. The benchmarks are mostly not compatible so it's hard to judge, but in Cinebench R10 the mobile Llano gets 2037 while the desktop gets 3390. I agree that for graphics it looks like the desktop part is performing worse in games, which is strange considering the GPU is working at a faster speed.Only explanation I can think of is that the faster CPU is taking too much memory bandwidth, but it doesn't make much sense since it's been said that the GPU gets priority. It's definitely something that's worth checking out with AMD.

http://www.anandtech.com/show/4448/amd-llano-deskt...On average the A8-3850 is 58% faster than the Core i5 2500K.
Boom. Delivered. You think its slow? It really isn't. The A8-3850 has about the performance of a DESKTOP i3. If you think that is bad performance, then you don't know what you are talking about. The battery life is amazing for having that kind of performance in a laptop. I'm sorry, but it totally destroys i7 and i5 platforms because of the sheer performance in that amazing battery life.
JarredWalton - Friday, June 17, 2011 - link
Let me correct that for you:On average, the A8-3850 fGPU (6550D) is 58% faster than the Core i5-2500K's HD 3000 IGP, in games running at low quality settings. It is also 29% faster than the i5-2500K with a discrete HD 5450, which is a $25 graphics card. On the other hand, the i5-2500K with an HD 5570 (a $50 GPU) is on average 66% faster than the A8-3850.
Boom. Delivered. You think that's fast? It really isn't. The 6550D has about the performance of a $35 desktop GPU. If you think that is good performance, then you don't know what you are talking about.
At least Llano is decent for laptops, but for $650 you can already get i3-2310M with a GT 520M and Optimus. Let me spell it out for you: better performance on the CPU, similar or better performance on the GPU, and a price online that's already $50 below the suggested target of the A8-3500M. Realistically, A8-3500M will need to sell for $600 to be viable, A6 for $500, and A4 for $450 or less.
