Llano in the Wild: Toshiba's Satellite L775D-S7206
by Dustin Sklavos on August 12, 2011 12:45 AM ESTBringing Gaming to the Masses
Where I honestly believe Llano shines is in its ability to bring a usable CPU and solid if unspectacular gaming performance south of the $600 price point. Similar configurations to this 17" Toshiba Satellite L775D-S7206 can be had for around $549 or less if you don't mind going down to a smaller, more portable form factor; Toshiba even offers a 14" notebook with the same APU and 4GB of RAM for just that price.
Low Detail Gaming
While Mafia II and Metro 2033 continue to punish most any notebook that dares to try and run them, and StarCraft II remains staggeringly poorly threaded and CPU limited, the A6-3400M and its Radeon HD 6520G graphics hardware are able to provide playable gaming experiences in almost every case, oftentimes even at the notebook's native 1600x900 resolution. It isn't ideal, but it's a big improvement over even Sandy Bridge's IGP, although the loss of four TMUs and 80 shaders going from the A8 to the A6 is definitely felt. Interesting to note is that the 6520G in the A6 typically handles 900p slightly better than Intel's HD 3000 handles 768p.
Medium Detail Gaming
Llano continues to put in a reasonably strong showing at medium settings, though the relative weakness of the four slow Stars cores is felt here. Much like with Brazos, it seems like AMD has crammed just a little too much GPU into these chips, more than the CPU halves can handle. Still, if you want to game on the cheap, the A6 can largely make it happen, with even 1600x900 gaming not entirely out of its reach in some instances. At our Medium settings, Intel's IGP also starts to fall off quite a bit, with very few titles in our suite managing to break 30FPS.
High Quality Gaming
Just for the heck of it, I figured I'd punish the A6-3400M all the way by running our suite of gaming benchmarks at our "high" preset.
900p proves largely to be too much for this class of graphics hardware; even NVIDIA's dedicated GeForce GT 540M struggles with it. Still, the results are notable and not wholly academic: Llano brings integrated graphics essentially on par with low-to-mid-end dedicated graphics hardware, and that's an achievement. The A6 takes a definite hit compared to the A8 in the GPU, but it still grossly outclasses Intel's HD 3000.

Let me guess. It slows down your web surfing experience, right? I mean pathetic 100Mb LAN socket on a device which 90%+ of the users would never ever use and the rest will use it only because there is no wlan. Shameless...Dustin Sklavos - Friday, August 12, 2011 - link
The issue is that it's a checkbox feature that shows up on absolutely everything these days, and if you're sharing media over your network as people are doing more and more, it's going to make a difference. The omission is silly.nitrousoxide - Friday, August 12, 2011 - link
Yeah, without this review we are already aware how awful Llano's CPU is. That is a truth given how low the frequency is. I own an Acer AS5560G with A6-3400M and I've done several tests on overclocking and undervolting the Llano.The A6-3400M can be safely undervolted from 1.05V to 0.90V without failing LinX stress test. This results in 2W power reduction in HD video playback and internet browsing, 3.5W power reduction in 3D games and up to 8W reduction in stress test. Peak temperature also drops by 12 degrees.
If you want to trade some battery life for performance, just overclock it to 1.8GHz and it runs stable at 0.95V. Then you get a 30% faster processor without consuming more power than stock A6-3400M. In fact, in stress tests, the overclocked A6-3400M consumes 4W less than stock. What about overclocking at stock voltage? At 1.05V you can bump the frequency to 2.4GHz, but this results in overheating.
As far as I know virtually every Llano can be massively undervolted or overclocked. It appears to me that AMD is too conservative with Llano's voltage and clock speeds, perhaps due to the fact that Llano is released in a hurry. They could've get a much much faster Llano just with some more tweaks.

There are a lot of people overclocking and undervolting their HP dv6zqe's into the 2.2 and up ghz range. Apparently the chips are unlocked.I have the dv6zqe and it is going well, except the 6750M (yeah, I did the crossfire) sometimes runs hot/noisy. I have not tried overclocking/undervolting but probably will sometime in the future (probably after it goes off warranty).
I think AMD could have tweaked voltages and clocks on the better chips so that there was model that had a 2.4 stock/2.8 turbo cpu with maybe a 550 or 600 speeds on the gpu portion - that could eliminate the need for a crossfire or perhaps improve the timing so that it is a bit more symmetric. An A8-3550MX or A8-3570MX, if you will.
The other issue - for those that got MX chips, HP is only using 1333 memory chips, when it looks like 1600 mhz is supported (for the MX llano's) and would give better graphics results. This toshiba looks like it doesn't have MX chips, so 1333 is probably the max memory speed. I wish laptop manufacturers had a 1600 option.

It is the newest version of k10stat, correct?Novaguy - Saturday, August 13, 2011 - link
Yes, it's one of the recent versions of k10stat. Maybe the last two versions, as I vaguely remember reading that a new version came out. There are a whole bunch of tables of volts/speeds on various forums using this program.I have not personally tried undervolting/overclocking as I have not installed anything that needs more performance. So far I am just doing browsing and playing early 2000's rpgs (diablo II) and the stock speeds are sufficient. But once I finish that I might move on to something that needs more fps....

"I'd've killed for a Llano-equipped notebook that could run something like Guild Wars on the battery with good performance. There is a market for this"True, 3D battery life is a standout for Llano, but I want to see a 35W A8 Llano sporting 400 shaders shoe-horned into a 12" chassis.
Now that would be made of WIN!

At the price point i5-2520M is out of the league. I'd like to see i3-2310m in the chars. Tho results AMD-Intel would be the same, Intel wins CPU-tasks AMD Graphics.oceanrock - Thursday, August 25, 2011 - link
I can tell you that the i3-2310 w/o dGPU (ACER timelineX 5830T), was faster, but not as smooth (responsive and enjoyable) as an ACER Aspire AS5253-BZ849 equipped with an E350!The i3 was constantly shifting its speed and spent most of the time at ~800 mhz and 20%utilization, the E350 spent most of the time at 1.2/1.6 ghz with 50-80%utilization. it still lasted 4-8 hours and kept real cool the whole time. the i3 was a bit louder, jerky, not as cool, but lasted 8-12 hours. Also, it cost $100 more...
Go figure???

Anandtech, could you please find a way to label laptop comparison graphs with the relevant HD/SSD model or specs? In some benchmarks the HD or SSD is more relevant than the GPU, yet the graphs seem to give all the credit/blame to the CPU or GPU. These days the CPU is often fast enough for many office/school tasks and the storage system is the bottleneck.
