I know, but I'm tired of AMD taking on Intel with more cores and not clock-for-clock, be it Opteron vs Xeon or Phenom II x6 vs C2Q and gen1 i7, I want AMD to get back to at least 1 : 1 parity Hz for Hz with Intel, just like I want Radeon USPs to be 1 : 1 parity with a Geforce.

AMD seem to want to get their stuff sorted. AMD's Graphics Core Next (GCN) I've seen described as "Fermi done right", that looks very interesting. They've also been working hard to improve imstructions per clock on Bulldozer. Shame they weren't released when they were meant to so we'd have an answer on how well they perform.

Considering the fact AMD has to do a lot with a fraction of the budget of nVidia and Intel, they don't do to bad

Read this last night. Not sure how unbiased Theo Valich is as a reporter, but seem him accussed of bias before. There's a whole thread in the Anandtech forums dedicated to his credibilty, or lack of.

Yeah, I felt pretty hacked off when I read it. He mentions the B0 and B1 steppings in the article which we know have performance issues, so maybe they've been resolved with B2. Or maybe they haven't. I'm rather skeptical to be honest. It's another article with un-named sources by a guy who has his integrity called into question before, his AMD source may be one of their top engineers or it may be one of the little guys.

In any case, i really think that Bulldozer will be a ( hopefully ) significant improvement over the PII's no matter what.
AMD can't afford to release a pig into the wild. They will go down if they do and they know it.

Yeah I read that a few days ago. Not so much to do with Bulldozer there, although I'm sure people will say that AMD quit BAPCo ostensibly because of the lack of GPGPU support in Sysmark, but the real reason is because of poor Bulldozer performance in Sysmark tests. It could also be, as AMD claimed a few years ago, that Sysmark uses Intel-optimized software so wouldn't show the full potential of AMD processors.

I'm not sure where this leaes me. I bought a Crosshair V Formula and was going to build a brand new system at some point. DO I stick with it and hope Bulldozer is fine or do I return it and pay through the nose for a similar spec Intel board and a SB processor?

From what I heard VIA and nVidia also quit BAPCo as well for the same reason, not making a neutral benchmark, so that only leaves Intel there for processors...I wonder where that synthetic benchmark will show every single Intel processor...

As GavinT mentioned, only B0 and B1 steppings were mentioned.

A huge part of this year's delay was to get B2 and C0 ready.  Remember that regardless of performance, we can be pretty confident that pricing will be spot on.

The thing about that is Bulldozer will have to give such a performance boost over Phenom II across the board to make many of the Phenom II crowd spend all that money on upgrading. They're going to need to show a "Core 2 to i7" level performance boost for me to even consider it this year

Has a C0 stepping been confirmed as coming out?

Do you really think AMD wants to confirm ANYTHING at this point?

If it's so, I don't really know why some models are getting the C0 treatment and others not unless the C0 models arent to be launched right away... that's my suspicion.

There are posts on the interwebs saying there will be a C0 stepping, although I suspect they're more speculation and conjecture rather than anything an AMD employee may have anonymously said to an online journalist!

Think about it too, since AMD has time to do another stepping, why not go ahead with C0 now so you don't have a stockpile of useless chips and you don't come out looking like a ***** company by releasing a chip and then weeks later releasing an optimized version of that chip. AMD is really in a bind though, completely new architecture, Sandy Bridge performing extremely well, lots of anticipation as this will also affect Trinity...

Trinity, Weatherford and Richland have some time before they are released, 6 months at the earliest, so they can iron out the bugs in Bulldozer for that.

The hope is that this gen 1 Bulldozer delay has allowed them to have this done already...

They don't even have to have bugs, it has to do with their performance in general. If Bulldozer only gives 25% performance advantages over Phenom II, they can't screw another 25% out

Mixed metaphors,  I meant iron out the kinks...but the sentiment is the same. Bulldozer-based APU's, aren't due for release until H1 2012, that could be January or June next year, so they have time to get better silicon ready.

And if you believe Wikipedia, the Virgo platform will use Enhanced Bulldozer cores, not Bulldozer.
