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...

    Tell ya what. The benefit is we get paid trolls like you over here. Reply

    How many monitors can you connect to this with a discrete gpu? Can you do 3 or more DVI/HDMI montors between the motherboard output and a discrete gpu? Reply

    The other dude hit it on the mark. The target for this is OEM parts for budget desktops. So the point about the discrete GPU being more cost effective is moot

    So given that...it's great that finally everyone can game adequately.

    1920 x 1080 on integrated? unheard of in my time

    OK, so maybe it's better than i3 for laptops. But what I was looking for in Llano was a greatly improved per-clock efficiency in the CPU, something that will drag AMD back into true competitiveness with Intel.

    Instead we get slight tweaking.

    If Bulldozer doesn't deliver a better CPU than oft-tweaked cores dating back to Hammer, AMD is dead on the desktop. Low-end laptops will be the only place they can compete, at least until Intel completes implementing DirectX 10 and 11.

    Bulldozer will deliver .. and it will kill Intel at it's price point, I bet your head on that ;)
    And Intel will be dead on the Server market, you can expect a 30+% perf/watt advantage for Interlagos on release day, only dampened when Intel will release their first 22nm Xeon ---

    More blood in the water, better market for us.

    Bet taken. Bulldozer will be an underclocked, overheating monster. AMD is 2 years minimum behind with Bulldozer.

    Ivy Bridge will be out before Bulldozer... Bet on that.

    AMD is 2 years in advance with bulldozer, as it is not designed as a desktop processor, but a byproduct of Interlagos, which will very likely take a lot of server market share from Intel.

    I'd like to see how AMD could be two years behind, when Intel has been stretching a core design from core1 to sandy bridge ;)

    Bet on the fact that AMD has always priced their stuff right, Bulldozer is in i7-2600k range, that means it will beat it hands down.

    Ivy will be a win in desktop for Intel, but then again, this depends on how fast both Intel and GF can get to 3d-gate 22nm. (which if we look at current trends would mean Intel 6 months before GF more or less).

    You are completely wrong. Bulldozer was scheduled for release in 2009. It is 2011. Hence 2 years.

    Considering Conroe processors still dominate Phenom II x2, x4, and x6 processors from AMD. I would say AMD is behind. About 3 generations.

    GF is just now shipping its first 32nm chips. Still not a single heavyweight chip at 32nm. Intel has 32nm 6-core processors for over a year. Ivy Bridge is out this fall at 22nm.

    Are you just completely drinking the AMD Kool-Aide or what?

    If I remember correctly, Bulldozer's design was torn up and started again from scratch in 2008. This would undoubtedly increase development time, especially if they completely changed the design.

    And for the final time, stop spreading BS about Conroe dominating Phenom II. Even Penryn doesn't. There are plenty of instances where K10.5 beats the Core 2 family and in most cases where Core 2 wins, the difference is marginal at best, not to mention that a) there aren't any hexacore Core 2s out there nor any with any turbo technology, and b) any sufficiently high performing Core 2 parts are massively more expensive than anything AMD is shipping.

    I dedicated a HUGE post on this topic to you on Toms using Anandtech Bench data and you've obviously decided to ignore it so... believe what you like. :)

    Yeah, I exaggerated. But the only way to deal with the diluted is to use such devices. Perhaps they will think and research.

    Phenom II vs Core 2 is not even close clock for clock.

    Phenom II only wins in scenarios where it is grossly clocked higher than the similar Core 2. The 9650 is a 3GHz part, Ph II 980 a 3.7GHz part.

    The recently released 980 barely outperforms the 3 y/o Penryn Core 2.
