We did. In the overclocked results the CPU-NB and HT clocks were both at 2500 MHz. 3000 was not stable at the small voltage increase I gave it (1.25 V on CPU-NB, which was a bit of overkill for that clock but time was not on our side; I had the chip 12 days before the review published). FWIW

The discussion was about a Linux fix that somehow morphed into there being a miracle Windows hotfix out there. I have no idea how it ended up there, but there is no fix. All of the reviewers were on the same mailing list. AMD made no mention (and still has made no mention) of any sort of hotfix that would improve performance. Trust me, if it existed we'd have known about it. An up-to-date BIOS/UEFI is the main item people considering BD need to worry about.

Ours was 4.75 GHz for 24/7 clock, but we used a water loop. A real one, not one of those Corsair / Asetek deals. It's my setup for all reviews, Intel will get the same treatment with SB-E, assuming I can get the mount to fit.

Can someone fold on one of those please?
In order:
  • As far as anyone knows right now, there is none.
  • Yes, at least ASUS has - 0813 was the BIOS used in the review on the Crosshair V Formula and it's up on their site now. The version immediately before it (0805 IIRC) was what AMD shipped the boards with and 0813 was an optional update, we had the option of not updating so they are definitely compatible with 0813.
  • You're not the only one to ask (see question above yours). Unfortunately it didn't make it into our review, but I did manage to get results folding and posted it in the first post of the comment thread, which is quoted below.

Regular SMP work unit - 13698.9ppd

Bigadv work unit - 13859.2ppd

So between 13,500 and 14,000 at stock, which is right where it's positioned - around the PPD of a 2500K.
My $.02 on DC performance with these - no one is going to touch them with a ten foot pole unless they have free electricity.

7.6% seems like a rather large margin of error, does it not?

Seems like a decent chip, though not much of an upgrade over current stuff. Seems like they made things over complicated with the architecture then it needed to be.

Not a horrible chip, but for the money Intel is the better option(unless you're a blind fanboy). Might get one of the cheaper options for a general use PC, just for the hell of it.
I still believe that this chip falls in between the 2500K and the 2600K in overall performance. It is undoubtedly better than the current PhenomII's, including the x6's for most rendering/encoding tasks, and even for most games.
I do believe performance will only increase as programs or optimizers are released for the BD chip.
Is it worth the price premium over the x6 chips? That's really up to the end user.

I never expected Bulldozer to give a beat down to sandy bridge...but i did expect more than this. If AMD doesnt find some more performance somewhere and fast, This cpu isnt going to sell well.

I can't agree with this. Enthusiast does not imply high cost.

Final performance per dollar of Bulldozer CPUs is not bad at all, and platform costs are extremely competitive.



Because the cores are narrower and share an FPU?

It was clear that some sacrifices would have to be made to fit 8 cores in the same transistor count as their previous six core chips, which already had inferior IPC to the last two generations of Intel processors.

Not all cores are created equal.



How many threads does TMPGEnc use?
Well it can't compete with the enthusiast market for 1 reason. power consumption, you have to add a much higher watt PSU just because of your CPU to run this chip.

It has a power appetite than much greater than what the 900 series chips from intel had. That's a huge price increase to your build to compensate.

You know when you look at multi-threaded performance the Bulldozer cpu performs very well. I know we aren't there yet on the software side but we will be and at that time this type of architecture will shine.

An interesting chip and all the content creation guys will have a new favorite cpu.

Not sure if I can justify getting a 990x board and a 8150, id almost rather get a 2500k/2600k and an intel mobo at that point even tho i was looking forward to bulldozer.

It doesn't fall in between the 2500K and 2600K. Look how many times it loses in these results:
