Battery Life, Portability, Heat, Software
Although lackluster performance has plagued AMD’s mobile processors for some times, I submit that it hasn’t been the company’s most pressing issue. That honor must be awarded to the woeful battery life endurance of AMD’s older mobile processors. Even AMD’s latest Athlon II and Phenom II mobile processors have been at an obvious disadvantage to the competition from Intel, and the problem has only grown worse with the release of the second-generation Core products.
The early Fusion E-series APUs provided a glimmer of hope. Although the models we tested (the E-240 and E-350) couldn’t provide life on par with Atom, their endurance was still respectable considering how thoroughly these APUs trashed the aging IGP found on Intel’s netbook processor.
The A-Series seems to make good on the better battery life promised by the early Fusion APUs. The testbed laptop provided by AMD came equipped with a 58Wh battery, which is a typical size for a mainstream laptop priced around $800. Out of this the testbed squeezed just over two hours of battery life in the Battery Eater Standard loop but nearly seven hours and a half out of the Reader’s Test and over 5 hours of WiFi usage.
The significant gap between the Battery Eater Standard and the other benchmarks tells us that the switchable graphics is doing its job. Battery Eater Standard engages the full might of the testbed’s dual graphics, sucking down battery wildly, but the GPU winds down when it isn’t needed and the battery stretches its legs. The Llano testbed bests the recently reviewed ASUS K53, which was equipped with a second-gen Core i5 and Intel’s HD 3000 IGP. It’s not possible to make an accurate prediction about how laptops based on A-Series APUs will be designed with access to a single system, but it appears that your typical system will give Intel Core laptops competition in endurance runs.
Battery life aside, the portability of the testbed is average, and I imagine that the same will be true of similarly equipped retail systems. The laptop easily fit into my messenger bag and didn’t add significant weight to my load, but this system’s dimensions are not particularly slim, no doubt due to the cooling the discrete GPU requires. This is not a problem, however, in my opinion. As sexy as paper-thin systems are, there isn’t much practical benefit to reducing a laptop’s thickness below an inch. After all, most of us carry around backpacks and messenger bags rather than manila envelopes.
The testbed system was quite warm after benchmarking or running 3D games. This heat output was noticeable not only on the underside of the laptop, but also on the laptop’s palmrest. Production laptops could solve this issue with better cooling systems, and it’s also worth noting that the testbed’s system fan was not aggressive, resulting in higher temperatures but less noise. Still, some heat output should be expected under these conditions. That’s simply the trade-off you must endure if you’d like reasonable graphics performance in a reasonably small package.
Software and Additional Features
The hardware in Llano is a drastic departure from previous mainstream AMD laptops. The inclusion of dual graphics in some models, alongside switchable graphics, has introduced more variables. Depending on your needs you might have dual graphics on, off, or configured to work with certain applications but not with others.
AMD has had to throw in software, called the AMD VISION Engine Control Center, to let users configure their hardware. The switchable graphics option has the capability to choose its mode of operation on its own, but by default it often asks the user for input. If you hated Window’s UAC, you may not much like the constant prompts asking how you’d like the switchable graphics to operate with a given program. There are just two settings – Power Saving and High Performance – and your settings are saved once you’ve chosen, so eventually the prompts will be a rare occurrence, as all of your frequently used software will already be assigned.
Navigating the VISION control center is painless. Most options are clearly labeled and not difficult to understand. The software is quick, as well – no waiting for menus to load. The overall presentation is superior to that found on current systems equipped with Nvidia’s Optimus switchable graphics solution. Although Nvidia’s controls are functional, they’re less attractive and somewhat more confusing.
Switchable graphics is far from the only feature in the VISION Engine Control Center. All of AMD’s typical GPU features are here including Eyefinity multi-monitor support, Hydravision multi-monitor desktop management, and audio via HDMI. Although these extras won’t be the make-or-break for most buyers, they’re always nice to have.

Thank you for posting this – it’s a great read.
A typo – you have “The graphics portion of the Llano A8 processors is going to be marketed as the Radeon HD 6620G. If you also have a Radeon HD 6770M discrete GPU in your notebook the combined product is the Radeon HD 6775G2. The A8 6620G paired with a Radeon HD 6630M GPU will be a Radeon HD 6990G2.” I believe that you mean “6690G2” rather than “6990G2”. 🙂
Thanks, fixed!

In the mobile form factor, CPU performance is less important than overall usability and battery life.
Desktop processors will have a MUCH tougher go at it.

stupid question whats up with
stupid question whats up with $2339 compared to a $600 system?
to be fair, test a sandy bridge system in the price range and not some overpriced gaming system that is NOT in the price range
you guys should also compare it to a amd based mobile phenom II and mobile athlon II laptop too
$2339 = Maingear eX-EL15

anyway, good review, very informative
We wanted to give a general
We wanted to give a general overview of how Llano compared to EVERYTHING. We did include the K53/N53 for that purpose as well.
This is the same reason we through the Core i7-990X CPU in with our $200 CPU tests. People want to see those comparisons.
From the MSI GT680R onward
From the MSI GT680R onward I’ve started using the new PCMark 7 and 3DMark 11 benchmarks where possible instead of their older siblings. In the long run I think this is the better idea, but I’ve only tested the MSI and Maingear since making that switch, so they were the only laptops against which to compare.
I did try to make clear that the MSI and Maingear are MUCH more powerful machines, and the A-Series laptop performed well considering the competition.
Yeah, I didn’t understand
Yeah, I didn’t understand that either. You’re pitting i7’s w/ high end discrete cards against a system w/ no discrete cards on a hybrid xfire thats still be fixed up?
I’d rather see comparisons that make sense, like ya know, a stock sandybridge w/ its trash IGP vs Llano in gaming. ANyway, I can’t wait to pick one of these up if the performance is there. I hope they can fix the kinks w/ the hybrid xfire so performance will be decent, or if it can allow graphics switching to its IGP and then back to the discrete for gaming.
Sorry for any grammar and
Sorry for any grammar and mechanical errors in my last post, but I think you get it.

The inexpensive gpu heavy platform looks like it could suit my mobile needs nicely, however I can’t help but fear that its price point will mean initial design wins will feature glossy plastic and glossy 1366-768 screens and other such cheapness. Please Lenovo, Sony, Samsung, or any one else, PROVE ME WRONG…

anyone know if this will be able to Xfire with any Radeon? to make a Bigger and better Xfire then we saw today? I mean it was only a 6630. What if it was a 6830M with the 6620M on the A8? Will this work?
Yep, it can essentially do
Yep, it can essentially do that with “Dual Graphics” technology to speed up gaming. The feature is listed and described on page 2 I think.
I believe it will only work
I believe it will only work with specific (mid range) cards. Xfire works through alternate frame rendering, so if the mismatch is too big, the faster card would be slowed down by having to wait for the slower card.
Your review fails to give the
Your review fails to give the average consumer–not geeks–some perspective on what this chips performance means. I will do it for you: people that can only afford one new computer for around $500 and want the portability and power efficiency of a labtop will now also have the option for entry-level gaming, somethig that was simply out of reach before. So parents, you can watch hd movies, surf the internet and run msoffice for 4hrs and beyond on one charge while your kids can borrow the labtop to play some–not all–pc games. I think AMD has a winning product for the mid to low end labtop,netbook segment.
I agree with this – as new
I agree with this – as new models based on this technology are released we will definitely be making these points.
Most buyers are so fool that
Most buyers are so fool that only know about Intel as Processor.They haven’t heard of AMD in there life. So computers with AMD will increase in sale but slowly.
People consult among there friends when they need to buy a PC. If a person buying AMD pc likes it performance very much he will tell about it to his friends and only this can increase the popularity of AMD.
Also in many homes there are children who likes to play games and they will like PC with AMD.
Benchmark here is not that
Benchmark here is not that good. Please compare AMD laptops with equally priced Intel Laptops. Intel laptops with i7 & Nvidia GTX 480 are very costly compared to AMD laptops.How can AMD match the performance of such costly Intel Laptops.
ASUS K53(2Core + IGP) is the
ASUS K53(2Core + IGP) is the biggest power eater in the Battery Eater Standard? It’s strange. I think it’s fitting that ASUS K53’s battery life is at least longer than ASUS N53(4Core + GT 540M).

Strange, but true. That was tested back in the ASUS K53E review. Battery Eater Standard + Intel HD 3000 = A quickly drained battery. I’m seeing a similar situation from another Intel HD 3000 powered laptop I’m currently testing.
Do not let the past repeat
Do not let the past repeat itself!
Intel engaged in unfair competition by offering very large rebates to worldwide PC manufacturers and oem sellers who agreed to eliminate or limit purchases of microprocessors made by AMD.
In the 90s intel used cash over product performance to keep its lead
You can read about this in Wikipedia AMD v. Intel
The lack of battery life
The lack of battery life kills this laptop. The poor processor performance also means many will turn to laptops for better experiences. Its a shame because the rest of what this laptop offers is just fine.
Ryan/Matt,
Great
Ryan/Matt,
Great write-up!
Maybe you guys can help me with this question. Suppose my laptop comes with just the AMD-A8-3510MX and the Radeon 6620G discrete-class graphics, would it be possible to add on, say, a 1GB DDR5 Radeon card to this later and still have it function as a Dual graphics? Any pointers on how I would know if the motherboard will support this.

This review of the AMD
This review of the AMD A-Series Llano APU Sabine Notebook Platform is good. Those who like notebooks would like the review. The photos of the notebooks look eye-catching. The charts giving details of the processor, RAM and hard drive are useful for us.
if i buy a notebook lets say
if i buy a notebook lets say samsung series 3 305V4A-S01 with a 6640g2 because it’s a 6620g with a 6450 i belive can i buy an hd 6770 and put it in my notebook? would it work?
