The AMD Llano Notebook Review: Competing in the Mobile Market
by Jarred Walton & Anand Lal Shimpi on June 14, 2011 12:01 AM ESTApplication Performance, Round One: PCMark 7
If the battery life was a pleasant change of pace, general application unfortunately remains a weak spot for AMD. Remember that Llano uses a tweaked K10.5 architecture for the CPU portion of the core, and while L2 cache per core is doubled relative to the previous generation quad-core Phenom parts, clock speeds and IPC (instructions per clock) still appear much lower than what Intel offers. I had hoped to see Turbo Core come into play here, which makes the comparison with Toshiba’s A660D a good starting point. That notebook has a Phenom II X4 P920 (quad-core 1.6GHz) with HD 5650M graphics, so the Llano A8-3500M has very similar specs.
Before we get to the graphs, let me make a quick note that not all laptops have been tested in all applications/games. Most of the systems have been shipped back to the manufacturer, so our newer benchmarks are going to have omissions (e.g. PCMark 7). In the gaming charts later in the review, we’ll have even more omissions, and many of the slower GPUs/IGPs will only be tested at our “low” settings.
With that out of the way, let’s start our application performance comparison with PCMark7, our only all-inclusive benchmark for laptops right now. We’ve run all of the benchmarks suites in the hopes of providing a better look at overall performance; however, outside of the “Computation” suite all of the tests have a storage element. That means any system with an SSD (like the quad-core SNB unit) will boast a massive advantage over the competition. The Computation suite also has an interesting footnote in that it supports Intel’s Quick Sync for video encoding, which again gives SNB systems a massive performance advantage. You can read more about the specific suites in PCMark 7 in their whitepaper. We’ll also have two results for Llano going forward: one for using the fGPU (6620G) and a second for using the dGPU (6630M).
And here’s our first hint that Llano may not be the homerun so many were hoping to see from AMD. All of the SNB laptops are still a healthy step up from Llano in overall PCMarks—the K53E leads by 43%, and systems with quad-core SNB are faster still. Llano might appear to at least surpass the previous generation Arrandale i5-520M in Dell’s E6410, but the storage subsystem in that laptop is a particularly slow 160GB HDD and that skews the results. Then again, the overclocked Arrandale i3-380M in the ASUS U41JF falls short of Llano, so AMD is at the very least competitive with Arrandale.
Since we’re not on a level playing field as far as storage, we won’t comment too much more here, but I do have SSD-based testing complete for four of the notebooks, and once I’ve swapped in an SSD for Llano we’ll have a follow-up article. Let’s move on to application testing round two, where we’ll look at some tests where we eliminate the storage bottleneck.

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.

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.
