    Phoronix: AMD Fusion A8-3850 APU "Llano" On Linux

    Late last month there were the first Radeon HD 6550D graphics benchmarks under Linux that were published on Phoronix. There has also been a stream of A8-3850 benchmark result uploads -- among other AMD Fusion APUs -- to OpenBenchmarking.org. In this review we are providing a set of computational benchmarks from this "Llano" Fusion APU compared to a handful of other systems in our labs.

    update

    My temp readings were wrong
    I got my /etc/sensors3.conf dialed in:

    k10temp-pci-00c3
    Adapter: PCI adapter
    Cpu: +32.0?C (high = +95.0?C)
    (crit = +95.0?C, hyst = +94.0?C)

    nct6776-isa-0290
    Adapter: ISA adapter
    Vcore: +1.18 V (min = +0.90 V, max = +1.26 V)
    +12V: +12.29 V (min = +10.85 V, max = +13.82 V)
    AVCC: +3.39 V (min = +2.98 V, max = +3.63 V)
    +3.3V: +3.38 V (min = +2.98 V, max = +3.63 V)
    +5V: +5.04 V (min = +4.52 V, max = +5.52 V)
    3VSB: +3.31 V (min = +2.98 V, max = +3.63 V)
    Vbat: +3.30 V (min = +2.70 V, max = +3.46 V)
    Case Fan: 1336 RPM (min = 600 RPM)
    CPU Fan: 1569 RPM (min = 600 RPM)
    CPU: +32.0?C (high = +55.0?C, hyst = +35.0?C) sensor = thermistor
    MB: +29.0?C (high = +50.0?C, hyst = +30.0?C) sensor = thermistor

    Not bad

    Ok, I just did that. I'm not seeing which section would contain the voltages

    Package (0x06)
    {
    0xFFFF,
    0xFFFF,
    0xFFFF,
    0xFFFF,
    0xFFFF,
    0xFFFF
    },

    bunch of those, so if that's what I think it is, then it's not being set right ....

    I think proper power management still depends on having the AMD proprietary driver installed.
    If you want, you can dump your DSDT and peek inside after disassembling it with iasl -d. There you can check if the voltages are determined by the BIOS correctly or not.

    powernow_k8

    now only if I could get the voltage to scale with powernow_k8 and the ondemand governor
    voltages aren't shown in dmesg after loading powernow_k8, only the clockspeeds
    the clock speeds appear to be changing, but power usage from the wall remains constant ...

    any ideas ?

    More benchmarks comparing to my old system and others

    Scythe Shuriken 100mm is the hsf I got
    the psu is fanless, silences and efficiency were my main goals with this build
    I'm not as concerned with high performance (I guess my tastes are changing)
    I had to modify the shuriken because the asus board has the cpu socket very close to the pcie slot. I simply bent the heatpipes leading to the upper heatsink moving it up maybe 20+mm

    Nice Setup, Soul_keeper!

    I also built up a system around the Q11 yesterday. But not with the A8-3850 (but nearly) - finances looked better so I took an i7-2600K+Asrwock Z68. Nice little setup! With a Corsair H60 (Mounted on a 140mm Alpenf?hn EKL Wing Boost as front Fan), CPU temps never go above 50?C in Turbo! The biggest problem were the stiff water tubes from the H60, but with some light pushing all fit perfecty. I did not take photos. If you are interested, I would go and open the case (8 tiny screws - YEAH!).

    The A8-3850 I would have cooled with Scythe Shuriken (not Big Shuriken, that one is too big!). You would need to turn the CPU-Fan around, so it pulls away the hot air from the MoBo/cooler, so the direction of the air flow is the same as the one from the PSU-Fan (sitting directly above the cpu-fan). With opposite directions, both fans fight for the air, which would probably lead to heat problems.

    ATM installing Gentoo. 7 minutes 48 seconds for compiling glibc - yeah! An Athlon II X3 435@2,9GHZ needs 21m 15s - impressive speed gain. The X3 with WD Caviar Black, the i7 with WD Caviar Blue.

    appears idle is about 60c and load is about 70c if the sensors output is to be believed

    I just thru in a radeon 6670 making the fit even tighter
    I had to do this because the asus motherboard had a dvi-d instead of dvi-i or vga

    Wow, that is an incredibly tight fit. Looks like the PSU barely fit. How do temps on the CPU look with that power supply sitting right on top of it?

    Ok, I got everything working

    First Small pts run comparing it to a bulldozer and my Q9450 system it'll replace

    the system idles around 50W compared to my Q9450 at around 100W idle

    I have pictures too
    this weblink could change later
