Take a closer look at the CPU-z screen. This tester disabled all cores but core 0 and OC'd the pants off this chip.

It doesn't seem reasonable that it would go backwards in performance.
Either the chip is a buggy ES,or the stats are fake.

After reading through the original Chinese thread, someone pointed out that because the chip he is using is the new stepping, a bug in the BIOS isn't reporting the correct speed. In reality, the 5.4GHz is actually 3.05GHz.

Edit: looks like Phantom123 beat me to it.

Hi all.
As I don't speak Chinese ,I will write in English so I hope you understand me .

First of all your Llano is not working at 5.4Ghz,there is a bug in bios.Actual clock speed is around 3Ghz (when you see 5.4GHz in CPUz). The ratio between REAL clock and what you see is around 1.75x. So when you saw 2.4Ghz it was actually locked at 1.4GHz,when you saw 4.7GHz it was performing tests at actual clock of ~2.68Ghz.. You get the picture . It is evident from your 3dmark06 CPU test,CPUmark99,superpi and ESPECIALLY AIDA64 results which are all in line with Phenom II @ ~3GHz.

So this Llano sample has some "brake" in BIOS that is limiting your multiplier to 15 or 15.5x,even if you manually select 54x.
So to recap everything:
-Llano's turbo mode is broken on your sample,
-real clock is 1.75x lower than what CPUz reports(2.4Ghz->1.4GHz,4.7Ghz->2.68Ghz,5.4Ghz->3.05Ghz)
-results are in line with Phenom II ,clock per clock,give or take a few percent.

Just wanted to point out this obvious thing to all of you,so you all don't think Llano is slower than K7 at the same clock speed .

Cheers!
QFT. +1 for finding this Phantom.

It would have been better to oc all cores, than disable all but core 0 and run it at 5Ghz.

Llano is supposed to be 90% the performance of Athlon II, but with graphics on the chip to more than make up for it.

As for the overclocks, Llano may be based on Phenom II cores, but it is also using 32nm transistors which means it should overclock a lot better. But who knows? 5.4ghz seems pretty unreasonable.

Only 90% performance of Athlon II? Yet it has Phenom II cores? You think they would have been able to fit L3 cache on it as well.
Graphics or not,there is no way this is even going to compete with 2nd. gen i3.
GG AMD,at least you make good GPU's.

No.
There will not be actual Bulldozer cores in a APU until codename "Trinity" in 2012.
