CPU Performance

For the full breakdown of x86 CPU performance head over to Bench and compare away. As I mentioned in our preview of the A8-3850 a couple of weeks ago, general purpose performance isn't that great. Although AMD has tweaked the A8's cores, the 2.9GHz 3850 performs a lot like a 3.1GHz Athlon II X4. You are getting more performance at a lower clock frequency, but not a lot more.

Compared to the Core i3-2100/2105 the A8-3850 really doesn't change the current state of AMD vs. Intel. If you're running lightly threaded apps, the Core i3 just has much better performance. Look at our single-threaded Cinebench scores below and you'll see a 50% performance advantage.

CPU bound gaming performance is also an area where the A8 falls behind the i3. Here you're looking at a 25 - 50% advantage for the i3-2100/2105:

Applications that are a mix of one or more CPU intensive threads still favor the Core i3 as you can see from the Photoshop performance results:

Go to the other end of the spectrum and load the A8-3850 up with CPU intensive threads, and it'll actually hold its own. As strong as the Core i3 is, there's no replacement for more cores when it comes to these thread heavy workloads. I should add that despite the A8's core count advantage, it's biggest victory in these heavily threaded tests is still only 9%:

There's not much more to be said here. The A8-3850 isn't going to set any records for general use performance. If your primary use for your PC is going to be gaming however, Llano has something to offer you...

    1366x768 would be preferable than 1024x768, for very few things use 1024x768 anymore, and 1366x768 is the default resolution for 720p tvs, 18.5 inch monitors, and older cheap monitors bought in the last 3 to 4 years. Reply

    I like to play games. 1024X768 is useable in a pinch. So bragging is out. Who cares? Reply

    What do you mean, image quality comparison? If two graphics cards differ in image quality, one of them does not work and needs bug-fixes. So your question is really, are there any bugs in graphics output on this "APU".

    Unfortunately sites often do "image quality comparisons" but it is nonsense, actually marketing nonsense.

    -Image Quality (IQ) here means the rendered 3D images of 3D games, the latest of them includes Crysis 2, DiRT 3, etc.

    -In most games, different levels of quality (quality setting like low, medium, high) is provided for scalability reason (so they can cater a wider range of customers).

    -Different GPU uses different algorithms/techniques or 'tweaks' to squeeze maximum performance at a given quality metric. So, in applying those tweaks, the rendered output is sometimes different between one another even though the quality level is same (e.g. High vs. High). Driver maturity is also another contributing factor.

    -FYI, Anandtech DOES provide IQ comparisons before, especially when comparing new Radeon and GeForce generations.

    -BTW, I hope the IQ comparison as promised by Ganesh would be available soon.

    Regards.

    Like the mobile version, Llano on the desktop is actually kinda impressive. Not necessarily for its current perfomance, but rather as an indication of what to expect from Trinity. With a significant performance boost to both parts of the CPU, I can easily envision my next laptop using Llano's successor.

    While its impossible not to compare these parts to Sandy Bridge, its not like a Phenom II x4 is hopelessly obsolete. Llano's desktop power figures are pretty good, but it seems like the 2105 draws way more power than it needs at idle -- my i5 2500k/P67 and a GTX 460 pulls 49w from the wall according to my P3 Kill A Watt.

    Still, I'm glad to see AMDs fusion initiative paying some dividends. It's good to have options, but I think it's time they stopped playing hard to get with Bulldozer.

    Hey .. I was just thinking, considering the scaling, would you just run those tests again with a decent memory kit ?

    I mean, most people buying Llano will probably get 1866 at the price of 1600, considering usual RAM market trends (1333 is dead/ price rising - 1600 is bottom price, many kits actually do much more than their SPD - 1866 is bottom within 3 months I guess, etc.).

    So, what about some real neat kits @ 2.2+ or even relatively cheap ones around 2Ghz ?

    I'm pretty sure that's where Llano will start making sense (or ... with quad-ddr5 .. 8 times the bandwidth should do the trick, right ?)

    I forgot one detail, there is no benchmark showing how that 6550D fares when you add a bit of shiny to your gfx settings, is it really so pitiful noone would ever consider pressing the button ? Reply

    i* cannot handle that, so writing such is a big no-no. Reply

    No overclocking section :(
    I know the ASRock A75 Extreme6 review covers it a bit,but not nearly enough(doesn't even tell us idle voltages)
    Was curious to see how it overclocks in a few scenarios:
    - with a discrete GPU (IGP fully sleeping)
    - with 2 CPU cores disabled (if it is even possible)
    - with the GPU starved by limiting the ammount of ram it gets
    - how far can it be underclocked

    Marketed for years as being something special (APU) but seriously it's nothing special at all. Intel was 1.5 years earlier (Arrandale). Agreed the power of the igp was pretty bad but still...

    This is basically only usable in the mobile version. And there it ain't to bad especially in terms of power consumption. Considering AMDs mobile track record in the last couple of year I would say its a pretty good comeback. And this was obviously its main target.
