AMD A8-3850 Review: Llano Rocks Entry-Level Desktops


I’ve had Llano in the lab for nearly two months in various stages of readiness. More than anything, in that time, motherboard BIOSes have evolved to the point where they’re production-ready, stable, and feature-complete. From one update to the next, overclocking goes from flat-out impossible to surprisingly scalable.

When the platform first landed, I was concerned about how it’d fare against Core i3—a processor we’ve already established performs exceptionally well in the company of discrete graphics. But Core i3-2105 itself costs $140 and a Radeon HD 6570 adds $70 to that bill. That’s an entry-level graphics card, too. Between the pair, you’re already over $200.

Strip Core i3 from the add-in graphics component that makes it shine and you’re left with HD Graphics 3000. While significantly faster than HD Graphics 2000, Intel’s best integrated effort can’t even come close to the engine built into AMD’s A8-3850. When you consider the LGA 1155- and FM1-based packages on their own merits, the Llano architecture makes a lot more sense. This is a simple matter of cost and balance.

We’re huge proponents of balance. You put the right processor with the right graphics card and the right memory. When you find the sweet spot for any given budget, you get the best all-around performance. That’s the entire premise underlying Paul Henningsen’s Building A Balanced Gaming PC series. Intel and AMD each made judgment calls when they were designing their respective next-gen products. Intel put most of its focus on very powerful execution cores. As such, its dual-core part is often able to beat AMD’s quad-core implementation. But AMD sunk more resources into on-die graphics able to complement the mainstream cores.

Source: AMD. The result of different priorities

The result is that Llano, as a package, is more balanced in a world where 3D pervades. Take 3D out of the picture and Sandy Bridge is superior. You really can’t downplay 3D, though. At least for most of us, we touch 3D-oriented content on a regular basis. For those workloads, Sandy Bridge really requires a discrete GPU in order to excel. That’s where you run into the cost component.

Specifically, A8-3850 (the only APU for which we have performance data) doesn’t rely on any other hardware to enable reasonable performance. Pair it up to a low-cost motherboard, 4 GB of fast DDR3, and a sub-$100 hard drive and you’re looking at a very entry-level machine that can do many things moderately well. For $135, you get a processor and GPU in a 100 W package. At $140, Core i3-2105 gives you a killer CPU and an afterthought of a graphics engine. I still love what Intel did with Quick Sync, but it’s telling that the company dedicated transistors to hardware-accelerated transcoding rather than spending them on more complex 3D capabilities, where it knew it couldn't compete.

Now, Who’s Going To Buy It?

I really would have loved to had time to test AMD’s Phenom II X3 720 Black Edition with a Radeon HD 6570 for this piece because those two parts cost about the same as an A8-3850. Overclocked through its multiplier, the Phenom II is almost certainly faster than Llano’s very Athlon-ish design. And the discrete GPU is absolutely quicker than the Radeon HD 6550D logic inside of Llano.

But that’s an enthusiast-oriented brute force approach to more speed involving a 95 W processor and a 60 W graphics card. A8-3850 more elegantly tucks its feature set into a 100 W part. Perhaps AMD is counting on system builders deriving additional value from the smaller physical and thermal footprints a Llano-based machine leaves compared to existing Phenom and Radeon combinations.

It goes without saying that this isn’t technology for enthusiasts. Even mainstream gamers with $500 bucks to spend on hardware can do better than the best integrated graphics we’ve ever seen. The fastest Llano-based APU is aimed squarely at entry-level desktops and all-in-ones—folks with $400 or $500 for a complete machine. For anyone else, quicker options are available at only marginally higher prices. AMD sees its addressable market between $400 and $700 with these APUs. Frankly, I think the $400 to $600 range is more realistic.

That still leaves a ton of ground for AMD to cover with the Bulldozer launch. But we have to be less than a couple of months out now. The question of whether it’ll catch up to Sandy Bridge and give power users a reason to revel in the FX suffix yet again will soon be answered. Until then, Llano is a cool piece of tech for your more mainstream mom and dad.

    Great review! Thanks Toms
  • Tamz_msc
    Another win for AMD!
  • SteelCity1981
    So then what's the point of getting the Turbo Core versions when they are going to be Turbo Clocked slower then the none Turbo Clocked versions...

    They don't want you to see better performance from a cheaper APU in single-threaded apps by pushing Turbo Core further ;-)
  • Known2Bone
    i really wanted see some amazing gains in the content creation department what with all that gpu power on chip... oh well games are fun too!
  • ivan_chess
    I think this would be good for a young kid's PC. It would be enough to run educational software and a web browser. When he grows up to be a gamer it would be time to replace the whole machine anyway.
  • DjEaZy
    ... it's may be not the greatest APU for desktop... but it will be a powerful thingy in a laptop... the review was nice... but in the gaming department... would be nice to see a standard 15,x'' laptop resolution tests @ 1366x768... or something like that...

    Actually if you want good DDR3 1600 with aggressive timings, the Ripjaws X series memory that I have does DDR3 1600 at 7-8-7-24 at 1.5v, not all that expensive when it comes down to it either.

    This makes little sense. An Athlon II X3 445 ($75) and a HD 5570 ($60, on a good day you can get a 5670 for the same price) would provide better performance for the same price ($135) and not have to worry about the RAM you use.

    So is AM3+ going to be retired in favor of FM1 in the near future? Why are there chipset at all? Why isn't everything SOC by now?

    Otherwise this is a very good CPU. If AMD has used 1 MB level 2 caches in their quads when they came out with the Deneb Propus die, they would be much more competitive.
