The AMD Llano Notebook Review: Competing in the Mobile Market
by Jarred Walton & Anand Lal Shimpi on June 14, 2011 12:01 AM ESTFusion GPUs: A Long-Awaited Upgrade to IGPs Everywhere
During our conversations with AMD, at one point they mentioned that they prefer not to use the term “IGP” anymore since they consider it a derogatory term. I asked what we should call Llano’s graphics and they said AMD officially refers to it as the “Fusion GPU” (fGPU), so that's what we'll use going forward. Regardless of what we call it, though, there’s no doubt that the 6620G fGPU is a dramatic upgrade to the old HD 4250; in fact, the 6620G should also boast significantly better performance than Intel’s HD 3000…provided the CPU core doesn’t become a bottleneck. Let’s start with 3DMark comparisons to see just where Llano falls. Again, we have the 6620G and 6630M Llano setups tested, but now we’re adding CrossFire to the mix.
I’m including all of the 3DMark iterations to provide a broad view of graphics potential. The latest 3DMark11 release seems to be almost purely GPU-limited, but of course it requires DX11 support and thus many of the other laptops (including Intel’s IGP) fail to run it. 3DMark Vantage’s Performance defaults are about as demanding, and Llano comes out 40-50% ahead of Sandy Bridge’s HD 3000. Of course, Arrandale completely falls on its face in the Performance test, generating a result of just 161, but AMD’s old HD 4250 is only marginally better with a score of 238. Remove some of the demands with the Vantage Entry-Level preset and Sandy Bridge starts to close the gap, with the quad-core 2820QM actually coming out ahead of Llano. Things that make you go hmm….
Things don’t get any better when we look at Asymmetrical CrossFire (ACF) from Llano. 3DMark11 comes in a whopping 50% faster than the 6630M dGPU, or 78% faster than the fGPU. If that performance boost showed up in our games, things would be great, but unfortunately it doesn’t. AMD informed us just yesterday that only DX10 or DX11 games and applications will even work with ACF, so perhaps that explains why we see little to no benefit in 3DMark03/05/06. The Vantage Performance preset shows a respectable 38% increase vs. the dGPU and 68% over the fGPU, but on Entry-Level it’s only 11-14% faster, and in 3DMark03 the dGPU actually scored lower than the fGPU.
If we were to stop our analysis of graphics performance right now, I suspect there would be a lot of confusion. Llano’s fGPU is anywhere from being equal to HD 3000 to 50% faster; Asymmetrical CrossFire is either a boon or a bust. So which is it? This is why we only place a minor emphasis on 3DMarks; let’s get to some actual gaming benchmarks.

Civ5 and TWS2 are both tested with the latest drivers. The K53E was also tested with drivers that are at most a couple months old. Intel current lists the latest laptop drivers as 15.22.1.64.2361 from 4/13/2011, which is what I'm running on the Intel units right now. If there are some newer drivers that I'm missing out on, let me know and I'll go try them.duploxxx - Tuesday, June 14, 2011 - link
Nice review, it seems like there is a lot of work on CF.Actually I reviewed the Liano already months ago, I mentioned in the last mobile reviews that it will be better performing then the Toshiba with the P920 with really good battery performance. So it is a win -win for the budget line anyhow. Top line remains intel for the CPU power.
Regarding the quote:
Now if you want to have your cake and eat it too, the APU to wait for would be Trinity. Due out somewhere in the 2012 - 2013 timeframe, combine a Bulldozer derived architecture with AMD's next-generation GPU architecture and you've got Trinity.
Trinity will not only be an improved GPU it also has the BD core inthere which will offer much more punch. THe reason LIano is late is because of the 32NM process. It could have been released much sooner. Sure they took an outdated K10 and that is the main issue together with the not enough aggressive Turbo for single thread, they should have adapted this more aka BD.
But assumin Trinity is a rather late 2012 project (by stating 2012-2013) you are way way off...

Quote probably reflects an increase in pessimism due to recent events. Bulldozer is still not out, and AMD is said to have had a hard time getting clocks up. So sure, we're all hoping to see Trinity early in 2012, but anyone setting their expectations a little farther are less likely to be disappointed.duploxxx - Wednesday, June 15, 2011 - link
didn't i mentioned it would be launch faster then expected?http://www.cpuforever.com/showthread.php?tid=1574&...
the delay of Zambezi BD has nothing to do with real architecture issues.....

That's not the sites which posted on it, including Anandtech, said based on what AMD said (that is, that Bulldozer was not up to speed).Jamahl - Tuesday, June 14, 2011 - link
Was that really needed? I mean...really? Who the hell would do that and for what reason?ET - Tuesday, June 14, 2011 - link
I already got my E-350 laptop, but as Jarred says, Brazos just became less interesting. I'll be waiting to see what price point and performance the dual core Llano will have. What impressed me most was battery life, which is competitive with the E-350 laptop, and it'd be interesting to see how small and light Llano laptops will get.The other takeaway I have from this is that as usual I'm impressed at how far Intel has gone with its integrated graphics. Sure Llano gives it a good beating, but that's at the expense of a lot more die space. I imagine that Intel will continue to tweak its 3D cores and I can't wait to see how this race will develop.

What happened to power consumption?!Some of us get laptops due to the optimization in the power department over similar desktop parts!
JarredWalton - Tuesday, June 14, 2011 - link
Power = [Battery Capacity] / .98 [efficiency] / ([Battery life in minutes] / 60)So if you take the battery life charts, you can determine roughly what the total system power draw is using the above. Or you can look at the "Relative Battery Life" charts and get the same information as Minutes/Wh instead of converting into Watts.

In my work I get a lot of laptops to fix. If there is one game or genre that appears on 80% or more of them its......The Sims.
I also get asked a lot "if I buy this laptop will it play The Sims?"
Never ever been asked if a laptop will play Crysis or any of the games you use.
Just saying.
