    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.

    The i3 and i5 processors aren't quad core, they're dual core with multi-threading, which you've shown in your own benchmarks doesn't make that much difference

      The i5 IS a quad core.

        Like to have in the system description sent to openbenchmark more detailed about the RAM. The size of the ram is not as important as the frequency of it for APU products. As far as I see the APU results differ for A8-3850 APU more than 33% with different RAM in the system. As is there is no evidence if the result of the processor is good or bad. I know phoronix is an one man show, so it may take longer to change this.

          Wrong, the i5 is a physical quad-core.

            Phoronix Test Suite already supports doing the DIMM modules, including frequencies. However, under Linux, this only works when PTS is run as root since it needs DMI access.... So either the Phoronix Test Suite needs to always be run as root or there needs to be a new way to export RAM information in Linux.

              Very nice review. Now that you have that USB power meter, could you publish power consumption figures for idle/gaming/compute too?

                Depends on which i5 you're talking about. I believe all the desktop i5s are quad-core, but my laptop's i5 is a dual core with hyperthreading (basically an i3 with Turbo enabled).

                  Out of curiosity - have you tried and had any problems with Ubuntu 11.10 (alpha3) on these?
                  11.04 looks to install out of the box, but 11.10 gives black screens immediately (i.e during installation).
                  Thankyou for the comparison command line too.

                    If I remember correctly, starting with Linux 2.6.39 DMI information can be exposed via sysfs and can thus be made accessible by non root users.

                      Yup, and my Macbook Pro is an i7 but dual core. Call it an i3 + Hyperthreading + 4 megs cache and more turbo... or something....

                      The initial complainer should have done his research about desktop i5s, which I believe are all quad cores, before setting Michael straight.

                        Yes particularly since both CPU companies go to all the trouble of setting up sites just for this purpose

                        Here's the relevant one for the i5 2500k

                          future Laptop's

                          I think 2012 will be the year Laptops will finally catch up to the performance of PC/Desktops at near equal prices,
                          Thanks of course, to AMD's Fusion apu/gpu's.
                          Intel of course has nuthin' to really answer amd's gpu.

                            Catalyst Drivers, Gallium 3D ?

                            Now, if only AMD/ATI Graphics drivers will match the quality of Nvidia(Linux) driver's, then we're all set.
                            But, from the Linux games here, it looks like things are workin' pretty good so far (for august accrding to this review).
                            Yep, a nice cheap and powerful all-in-one desktop, with the thickness of a closed Laptop. PC Tower cases are out, flat desktop's are back IN.
                            Also, being that Arch's Linux kernels are always light-years ahead of Ubuntu's, this all looks very promising indeed.
                            HTPC lovers' rejoice !

                            btw, thx for the review/article.

                            Am I an AMD fanboy or what ?!
                            Lol.

                              Soon...

                              I have read that Unigine Heaven would nearly run with Open Source drivers. So I started it and to my surprise it worked on my mobile HD 6550 (= HD 5650) with mesa git and xorg 7.11. It is not fast and it had some rendering problems. The good thing is that it run at all (= all OpenGL extensions it needs finally implemented) and it didn't crash X.

                              Then I tried Half Life 2 episode 1 in wine. The rendering is perfectly fine, but with HDR it is very slow. Without HDR it's still not 100% fluent but is actually quite playable with no rendering glitches I saw. This has always crashed my X in the past.

                              It won't be long now until the Open Source radeon driver it is a good alternative to the nvidia closed source driver.
