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.

these prices, are definitively NOT in the netbook range:$500 - thinkpad x120e
$550 - HP Pavilion dm1
$600 - sony vaio YB
who the hell would pay that much dough for Atom level performance?

even AMD's slower 1.0GHz C-50, costs more than the Atom in the SAME MODEL netbook (while benchmarking slower than the atom!):$250 - Acer Aspire One 255 with the FASTER Intel Atom
$330 - Acer Aspire One 522 with the SLOWER AMD C-50

First of all, the (lowest) prices I found at Amazon.com were $250 for the 255 and $310 for the 522, which is a smaller margin.Acer 522 has a 720p display vs. the 255's 1024x600. That alone is worth a significant price difference. It also has a HDMI port and a CPU (APU) that can play 1080p HD videos (or 720p on the internal display). The 255 is worth crap for video playback, a very common laptop use these days.
The C-50 can also play some games. Sure, older ones and at low settings, but it's something the 255 simply can't do.
In terms of general performance, the C-50 should be competitive with the Atom when it comes to web browsing and word processing.
In short, the 522 is so much better than the 255 that a $60 premium is really not a lot.

"But, but, the 522 has an HDMI port on it!".Personally, i wouldn't pay $80 more for a netbook that is even SLOWER than an atom, no matter how much lipstick they put on that pig -- i mean, no matter how many hdmi ports they stick on that snail.
And they could stick whatever size screen they want on it, and i'm sure they would charge a whole lot more if they put a 55" on it, but i'd surely NOT buy it with a C-50 in it....
more bluntly: Acer could put a 1080p display on it, add USB 3.0, give it an amazing sound system, etc, and then charge $1000, but who wants a Ferrari with a Yugo engine?

Forget the C-50 vs. Atom. Would you pay more for an Atom netbook if it had a higher resolution screen? If not, then fine, but I'm sure many people would. 1024x600 is too low for comfort.From your post it looks like you're just trolling, since you stick to "$80 more" even though it's $60 in reality, ignore any comfort from higher resolution and continue to insist that the C-50 is "SLOWER" in caps even though it would beat the Atom in the 255 on SunSpider and probably other benchmarks of real world usability. So I think the prudent thing to do would be to refrain from replying to you, and I will try to do that in the future.

Sorry mate, i'm just slow, not a troll... though it's easy to confuse dain bramage with trolling.When i looked at amazon i saw their black one was "Currently unavailable", and the colored ones were $330. I didn't spot the black BZ465 that IS available for $310, so i cede to you that it is only a $60 difference.
My apologies.
"Forget the C-50 vs. Atom. Would you pay more for an Atom netbook if it had a higher resolution screen? If not, then fine, but I'm sure many people would."
That is a reasonable point. $60 is worth it to many people for a better netbooking experience. There is a LOT of value in a highly portable 10" netbook, with hours and hours of battery life, that you can toss anywhere (even a purse), and it does it's intended job of surfing and playing video (not 1080p, of course, but why would it, it has a freaking tiny screen), with a real keyboard and trackpad (and USB ports - take that, ipad). And with a dirt-cheap price, it's all smiles for "many people".
BTW, i did pay more, lol, except i had to go for an 11.6" screen (@1366x768), even though it isn't as tossable.... i also sprang more for an ultra-low-voltage, dual-core, U/SU chip, so i can have a little more fun, wasting hours on boxcar2d!

Where did you get these prices? The HP is $450 (3GB RAM, 320GB disk). The Lenovo is normally $440 for the E-350 version (though currently backordered). It's not rare to be able to get them for less.This is still more than netbooks, but it's for a better spec and better performance.
sinigami - Thursday, June 16, 2011 - link
(sorry, i admit my prices were not current, the price has gone down and i haven't kept track)still, that is getting very close to the price range where you can get a much better spec, and way, WAY better performance.
the performance that becomes available, for a few dollars more, first jumps to twice that of an Atom or Zacate, and then you get to the budget i3's, which are, at the least, FOUR times as powerful as an atom or E-350.

i fully appreciate netbooks for what they are, and i know better than to do anything more demanding than play my 720p MKV anime on a netbook (yes, even the latest Atom machines can do this).I'm just pointing out that, currently, with the Brazos and Zacate Fusion APUs, AMD is NOT hitting the price/performance spot that i expected them to.
the Zacate 1.6GHz E-350, should be priced the same as the Atom machines, up to the price of the Atom/Ion machines.
i was hoping for AMD's tradition of price/performance to continue, and that would have meant beating or at least NOT being more expensive than Intel!
and the C-50 is even worse!

I was wondering if they used the latest drivers from Intel, which offer some performance increase. And on the notes of Drivers, GPU drivers these days matter a lot more then Hardware. And ATI has had YEARS of Hard Work on their drivers. While Intel is working hard now, although in terms of catch up they are rather slow.Which brings the questions, If Intel really did improve their drivers and bring extra 10 - 20% increase. The Liano doesn't look that attractive at all.
