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

Storage Performance

When it comes to storage, AMD’s A75 chipset is more advanced than anything Intel currently offers. In contrast, the A55 chipset is a disappointing step backward.

The A75 platform features six SATA 6 Gb/s ports, software-based RAID 0, 1, and 10 support, FIS-based switching, and four USB 3.0 ports. Though integrated USB 3.0 connectivity is really the only new feature, we still wanted to test the platform’s complete storage suite.

SATA 6Gb/s: A Little Better, Perhaps?

AMD doesn’t specifically cite any improvements made to its SATA 6Gb/s controller. However, we still measured slightly higher sequential write performance and better random read/write throughput using a 240 GB OCZ Vertex 3 Pro.

Although Intel’s controller generally comes out on top, AMD’s improvements are significant enough to yield better sequential read performance, better random read speed, and near-parity in our workstation workload.

USB 3.0: Better Than An Add-On Controller

No longer the shiny new feature it once was, USB 3.0 support is expected on an enthusiast board today, even if the number of devices designed to maximize a SuperSpeed port is still small. Nevertheless, we have a few high-performance USB 3.0-based devices in the lab, so it makes sense to see how AMD’s integrated controller measures up.

Our 890GX-based motherboard, Asus’ M4A89GTD Pro/USB3, includes an NEC µPD720200 controller; our Z68-based Asus P8Z68-V Pro sports an ASMedia ASM1042 controller, and the ASRock A75 Extreme6 features the integrated AMD controller plus an additional ASM1042. We use a Kingston DataTraveler HyperX Max 3.0 to test performance. And while its 195 MB/s peak read speed doesn’t come anywhere near maxing out the interface, it’s an astounding improvement from what we’re used to from USB 2.0-based drives. Our test workload consists of 12 772 files in 621 folders occupying 56.9 GiB of capacity.

All three controllers are fast—we’re not used to moving more than 50 GiB in between six and eight minutes. However, AMD’s built-in logic finishes the task first, followed closely by the ASMedia controller on that same A75-based motherboard. The NEC controller comes in third place, while an ASMedia chip on an Intel Z68 Express-based board takes quite a while longer to finish the transfer.

Now, just because AMD’s controller is integrated doesn’t mean you get the convenience of a USB 2.0 interface. The USB 3.0 ports are completely unusable until you get drivers installed, which makes any remaining USB 2.0 ports valuable for keyboards and mice, particularly if you need to install Windows or change BIOS settings.

    stardude82That's about all the sense it makes then.


    Actually Llano on the Desktop is (IMO) aimed at HTPC a 100% and, off course, notebooks.

    I would really, really like to see more media features with the Llano parts you guys have if it can be done 8)

    Great article as usual!

    Cheers!

    Good lord reading the comments some of you people are really dense. Do you not understand the target market for these and can take the review in context????? Not everything should be looked at as though you are a custom power cpu/game builder.

    Great review Chris. For the target market AMD is doing a pretty good job here with an old CPU architecture and once they pair this with Bulldozer they should have a killer product.

    Heh, I love these comments - for $150 more than a $135 AMD CPU you can get a better Intel CPU and AMD GPU!

    No shit, really? I wouldn't have thought so, it's just twice the price!

    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 ;-)

    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!

    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.

    ... 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. http://www.newegg.com/Product/Product.aspx?Item=N82E16820231430

    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.

    what about power consumption?

    That's about all the sense it makes then, for mobile and all-in-one units, but for cheap desktops... eh.

    not bad but can you overclock the graphics core

    I completely agree with Yuka and was thinking the whole way through how amazing these would be (especially the low TDP versions) in a HTPC.

    In regards to dual graphics, the only game that it seemed to work on was WoW Cataclysm. What was the cause, drivers? CAPS?

    And I think you guys may have gotten the min and avg FPS scores for the CoD:MW benchmark backwards... How can the min be higher than the average? Maybe you were actually comparing No AA to 4x AA or something, not min and avg FPS?

    This review need IGP OC. The Llano GPU overclocks like hell.

    600Mhz to 840/900Mhz? No problem at all.

  • frozenlead
    On the COD graphs, the minimum and average FPS bars have to be switched...it's impossible to have a "minimum" data point greater than the average.

    Since when does a 100W CPU and a 6530 need a 850W power supply???

    Anyway, The real show should be bulldozer-based APU's. If they could just get the graphics up to a 5750 level...

    Great article. This really helps me out since I need to replace 2 laptops in the near future.
    As for a higher end desktop, I am waiting for BD and how it affects the market. That will determine which parts I keep and which parts get put into an HTPC.

    Definitely looks like a stopgap measure, a product with good execution but no market. Basically, the only people who will buy this are casual/lazy PC gamers - the serious guys would come to sites like this very one to find out that they can get way more for their money than buying Llano. Thing is, at this price point, most people don't even care about games. Like I said on a previous post, any serious, smart PC gamer will build their own or look higher in terms of pricing to get a genuinely strong system.
