Fusion 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.

Futuremark 3DMark 11

Futuremark 3DMark Vantage

Futuremark 3DMark Vantage

Futuremark 3DMark06

Futuremark 3DMark05

Futuremark 3DMark03

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.

    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. Reply

    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. Reply

    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. Reply

    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.

    I 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. Reply

    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.
