"ARS TECHNICA" "Bulldozer shows a significant reduction in single-threaded performance relative to the Phenom II. So great is the drop that even when run in multithreaded mode, the eight concurrent threads on Bulldozer can't keep up with the Phenom II's six threads, or even an Intel chip's four depending on the model they are designed to compete with (almost all)." "These are bad results for AMD. The FX-8150 is more expensive than the Phenom II X6 1100T (was) "good luck finding an 1100 Thuban", yet in typical desktop workloads its performance is no better, and sometimes even worse".

Don't take my word for it, I didn't write it.
When the results were in and all the fanboys were crying about Windows 7 being the cause of Bulldozer's poor showing, that's all I had to know when considering a so called upgrade to Bulldozer, I decided to wait for Piledriver, and will wait to see how it stacks up. I did the same with the original Phenom, I passed, and was glad I did, went straight from Athlon 64 x2 6000/6400+ to a Phenom II x3 720 Heka, clocked 3.8 Ghz and unlocked to x4, for $99.00, then sold them to customers in brand new builds when they were $79.00, when AMD has a winner, they have a winner, when they have a mediocre chip, they have a mediocre chip... I'm still waiting to see just how Piledriver stacks up, and it will determine what I buy for personal use in the future (GAMING)... B.T.W., have seen a 2011 socket 3820 4.8Ghz 24/7, seen em run at 5.0Ghz as well... A little warm, and pricey.
.
"IF" the day comes that AMD doesn't make any money for me, then that's the day they get dropped, I don't see it happening for building non gaming internet surfers, but if they keep putting out mediocre chips as a new release, then it's time to jump ship for gaming, regardless of brand "loyalty", and the last time I check neither "INTEL" or "AMD" was loyal to me, they are simply both non feeling corporations, who's only purpose is to make money.... Ethics debate aside, i'm going to go with what works, and what puts food on the table.
.
I hope by some miracle that Piledriver or Steamroller will be priced low and perform like a boss, it would be good for business.
On a side note, AMD is all I have used for gaming since 2008, so i'm not an intel fanboy.
.
The only advice should be... "BUY" what works for you, don't buy what "DOESN'T"...
Pretty much. Though real life tests show the FX processors to be nowhere nearly that bad. A number of quite viable benchmarks disagree for multithreaded applications. IPC fell no where near as far as Ars Technica was implying in that. On average, bulldozer is 5-15% slower clock-for-clock core-for-core versus Phenom II based on all the reviews and benchmarks I have read.
Such as Passmark:

Anandtech also disagrees, although it seems that their site is down at the time of this reply...
Anyhow. Piledriver (in Trinigy) has already been proven to be faster then Llano IPC by 5%, while being more power efficient. And with Llano more power efficient and having higher IPC than Phenom II, that is a decently good thing. Not to mention desktop Vishera likely getting architecture tweaks and getting L3 cache. And coming at 4ghz+ at stock, it's looking at least... competitive if chips come out at the current bulldozer prices.
