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.

Legit Reviews found a big difference in game performance between AC and battery (see here: http://www.legitreviews.com/article/1636/5/). This made Llano and the i5 perform about the same on battery in Resident Evil 5. I assume that benchmarks here are on AC, so it would be interesting to test on battery.DXM1 - Tuesday, June 14, 2011 - link
Great Review Anand! Once again we know intel is the best at all things computing. I liked how you included the i7 with 460m up to THREE times in some benchmarks. It was like you kept reminding us and casual consumers that massively more expensive parts perform better... Even if you test the same set-up 3 times in a row!I have to tell you that seeing the 3 intel blue bars on the top made me sigh with relief, I was worried that you may actually compare llano to the parts like i3 and i5 where it is actually meant to compete (like some other silly reviewers). My only gripe is you didnt add i7-2600kand gtx 580 OC'ed as those would have made the gap even wider from the AMD system.
One question I did have for you is, how much does Intel pay nowadays for dishonest reviewing practices? Im short on cash because my job doesnt pay well and I was hoping to open up a website and promote intel just like you. Maybe we could even become partners and link to each other websites I think that would be cool.
PS, could you post how much your integrity was worth before you auctioned it off to Intel? Im sure some of your fans would be eager to know.
Your ex Reader, DXM1

Dont feed this troll, Anandtech is a great hardware site.Jamahl - Tuesday, June 14, 2011 - link
Troll? it's the truth. What was the fucking point in showing 3x identical intel systems except to put 3x intel systems at the top of most benchmarks? It's goddam pathetic.JarredWalton - Tuesday, June 14, 2011 - link
Or, I included these laptops because they're the only ones I still had where I could rerun all the benchmarks (specifically, PCMark 7 and 3DMark 11). Oh, snap! Heaven forbid we think about that. And if you read the 8000+ words of commentary, you'll notice how often we praise Intel's placement at the top of the charts -- and of course we completely ignore when they fall to the bottom of the battery life charts.I wish I had a secret stash of all the laptops I've tested in the last six months, because then I wouldn't have even bothered with including more than one GTX 460M + SNB. But your suggestion that we *not* include laptops because it pushes Llano down is even worse than what we've done. Should we only show laptops where AMD is better? Or maybe just laptops that cost under $700? Maybe we need to dig out an old CULV setup and then benchmark GMA 4500MHD again so we can laugh at Intel's IGP from two years ago?
If you want a look at every laptop we've tested and where Llano falls in the grand scheme of things, I suggest checking into our Mobile Bench results. Hint: it's in the upper part of battery life, and in the middle to lower part of CPU and GPU tests; if you only look at IGPs, though, it's the fastest IGP. Hmm... that sounds a lot like what we said in our conclusion.

JarredI think its a fair comment that asks Anandtech to keep their graphs in an article consistent with the same laptop set across a testing segment. As you said, you had to rerun all the benchmarks so why are the Civ laptops listed so different from Mass Effect, Starcraft etc?
Thanks

The comment may be fair, and it's been mentioned before, but accusing Anandtech of being paid by Intel isn't.krumme - Tuesday, June 14, 2011 - link
None of this explains the 3 identical setup.How on earth to you think it looks like?
Its simply utterly pathetic, and an insult at our IQ
I am no fan at this Llano apu, and from the start. think AMD should just have posponed it, and used the capacity for BD and serverspace, but this review is just far out.
The important issue about llano have always been the power profile, and AMD just deliver in spades here. Far beyound expectations. The OEM will sell this like zakate, and the new trinity will not make it significantly better on the market than this with upgraded star cores.

You know what's utterly pathetic and an insult to people's IQ? The suggestion that they can't actually comprehend the graphs. But just to show you that I have no "agenda" and I'm not trying to make AMD's Llano look worse than it is, I have taken a couple hours to go through, remove all the extra data, and regenerate all the graphs. (Yes, folks, creating all of these things does take time and our UI for doing this is not as easy as you might expect.) Of course, not all of the i7-2630QM + GTX 460M notebooks performed equally, so now I've "punished" Intel by showing worse results in some tests. Oh noes!Anyway, thanks for the input and sorry if the inclusion of more laptops was deemed offensive by some. They're just charts, people, and I even colored the "high-end" laptops bright blue so that you could easily filter them out in your mind. You know, something like: "Oh, those lines at the top are bright blue, so they're for quad-core Sandy Bridge laptops that cost about twice what the Llano laptop is expected to cost."

Although I don't like the approach of the poster taking issue with the graphs, I completely agree on principle. This site has shown a clear pattern of making sure certain hardware always occupies the top of the graphs. Always. And don't insult our intelligence and pretend otherwise, please.Need I also remind people that this site included hand picked, overclocked Nvidia supplied cards (to the insistence of Nvidia) despite a policy that forbids this. I would caution people to take all results on this site with a grain of salt.
