AMD Fusion A8-3850 APU "Llano" On Linux

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).

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.

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.

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.

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.

Wrong, the i5 is a physical quad-core.

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

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.

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.
