I so badly wanted Bulldozer to compete, but it appears to only do so in only a few heavily threaded applications. Better luck next time AMD. Thank you for not giving me buyer's remorse as I have been running an i5 750 since its lunch.

"And it means that AMD didn’t succeed in launched a revolutionary desktop CPU."

Succeed in "launching"

"Overall, FX processors are faster than Phenom II, they overclock much better and consume considerably less power, so they will be a good replacement for the CPUs on old K10 microarchitecture."

Ilya, can you please provide load power consumption figures for the overclocked FX-8150 @ 4.6ghz vs. say an overclocked X6 1100T @ 4.0ghz?

The better power consumption may only relate to nominal / idle frequencies. However, Bulldozer needs to be overclocked to 4.6-4.8ghz just to keep up with 2500k/2600k. I imagine when you compare a 4.7ghz 2500k vs. a 4.6ghz FX-8120/8150, the power consumption difference will grow even more than at stock speeds given the much larger 315mm^2 die size of the 8-core AMD processor on the same 32nm process and higher voltage required to achieve overclocking frequencies.

Please benchmark x264 in CRF not 2-pass mode. Almost nobody uses 2pass anymore.

Wow been stressing over the Ath 64X2 still kicking hard, I have had for years since its launch and too bad I wanted the BD, Not now. BTW WOW and SC2 run just fine.

Big disappointment after all the delays and all the hype.

It's no surprise given the execs leaving AMD in recent months. Five years in the making and Bulldozer is busted flush.

no wonder they have been talking about piledriver even before BD was ever released!

Where did you see the hype from AMD?
The hype have been coming from AMD fans and not from AMD.
Do you not remember AMD' promises to deliver 50% more perf with 33% more cores (or a mere ~12% per core improvement) back in 2009? And that was just theoretical (read optimistic) estimate.
Do you not remember how in August this year AMD did correction and started talking about 35% more perf or ZERO per core improvement over old Opteron?
What reasons anybody had not thinking other way?
The reality turned into much more harsh way: w/ 33% more cores BD provides much LESS than 33% perf increase! But could anybody has expected that AMD had dared to speak aloud about it?

BTW, it would be very helpful if XBit includes charts w/ per core/thread bench numbers also. They are very impressive. I cannot recall the time when a brandnew arch provided worse numbers than the older one.

Even if I really don't want AMD to go bankrupt, the Bulldozer is so disappointing that I may buy the I5 2500k, I really wanted to go to AMD this time.

Go fot the X6 T series, that is what i did and do not regret it. great at gaming, chews through video transcodes, great chip and they can be had for cheap.

This is another sad day for IT industry. Not only for AMD fans but for everybody.

AMD should have never released a product which is inferior to the previous generation.

In Starcraft 2 for example Intel offers 50% more performance. I3 SB is not included in the charts, but in games it will be faster than BD also. Hek the 100$ Pentium G SB are faster.This is outrageous.

If AMD dies SB will be the fastest unchallenged processor on the planet for many years to come and price will go to unbelivable heights.

... So. AMD should have die shrunk the Thuban/K10, and made it 8 cores...... Probably would have launched in August (Less R&D)... Probably would have clocked to 4GHz.... Probably would have performed decently....

... The Bulldozer needs a bit of work, and each "Module" should be considered a single core. I bet that was AMD's initial expectation but I bet they couldn't afford the space in the silicon (or .... realistically GloFo's 32nm process isn't good enough).

I've been telling this now for almost a year - "BD will be a bunch of crap!" - Now that is been benchmarked, it is indeed crap!

AMD was just plain lucky back during the early days of the Athlon!

XBit Labs again comes through with explanations, not only a set of benchmarks.

The section titled "Estimated Efficiency of New Bulldozer Microarchitecture" in this review says it all: AMD made wrong choices when defining the Bulldozer architecture.

They must have figured it would turn out better, but it's simply a disaster that all these "module" design niceties can't even match a single Sandy Bridge core with hyperthreading.

Now we know why Dirk Meyer was fired as AMD CEO. It was not about some "vision thing" for the mobile market, as rumored. When the Bulldozer performance deficiency became apparent, he had to pay the ultimate price, as he was ultimately responsible for the architecture design fiasco.

Not Meyer only, and others, including Bergman. There is very long row and it will grow up.

It's a shame indeed. But I still do like AMD.
On the other side, now I'm starting to think about future of ARM architecture for the first time 'Cause I don't like Intel's monopoly anymore.

get over it fanboy! it's all over the internet! BD is a PHENOMINAL failure! The 8150 hardly performs past the 980?!? What other excuses do you have?!? AMD only got lucky a few years ago with the athlon! this time around AMD can just brag around about being able to compete on the netbooks market!

Dude I'm typing this on a Thuban X6, i also have a Bobcat netbook AND a socket 754 Sempron i use for a nettop, as well as just building an X4 deneb and an X6 thuban for my kids so if there is anyone that can say they are "pro AMD" its me and even I see the BD is an uberfail. The problem is this...they are trying to count hyperthreading as an actual core and it is NOT. you compare the FX 6 core to my Thuban and except for a couple of integer jobs my Thuban STOMPS it, hard.

So I'd suggest to all fellow AMD fans to stick with thuban and Zosma, both of which have plenty of speed and are REALLY cheap right now, and maybe by Excavator they will have this figured out. But hyperthreading is NOT a second core, okay?

So after numerous delays, months of waiting in anticipation, and keeping my mouth from watering over the Core i5 2500K, all AMD did was reintroduce the Pentium 4? I thought they knew better than to just blindly throw higher IPC count and energy efficiency for higher clock speeds like Intel did eleven years ago.

All the hype of Bulldozer's build up for months and it shows little gain over Phenom II's. For all of us waiting for AMD to beat Intels Sandy Bridge in which AMD claimed it would in many benchmarks, it has turned out to be dissapointing to say the least. So dissapointing that even the Phenom II X6 1100T is able to perform around the same level if not beat the FX 8150 8c in some benchmarks.

I do not understand how they kept the Bulldozer so long covered, when they could release it 1 year and probably the scale of the disaster could have been lowered.

Very disappointing performance from a revolutionary new architecture.
