As someone who sells X86 servers and VMware licensing, I can tell you that bulldozer looks to be a very good server architecture for running virtual machines. A 16 core CPU is going to save a customer alot of money on VMware licenses as they license per CPU not per core.

On a side note, I am looking forward to seeing more reviews on the FX-6100 and FX-4100 CPU's. These look much better price/performance wise for client computing. I suspect that we will see similar performance between the FX-8150 and FX-6100 in most benchmarks, especially when overclocked. Also I expect thermals to be much lower on the 4 and 6 core parts. These chips could be FX's saving grace.
So long as those sever chips don't have crazy power consumption, then they'll do fine in servers. We knew Bulldozer was server first, client 2nd.

does 4 single threaded mods of bulldozer beat a 4c phenom II though? or is it just the same? anyway AMD has some catching up to do in IPC

Mad beat me to it, but this is still a valid response.
Actually a large number of modern applications can utilize multiple cores.

Back when dual core CPU's released there actually was a decent number of dual core applications that were in development. These include both professional applications, and some games.

When AMD released their first dual core CPU (X2) they didn't forsake single thread performance. They realized that a lot of software was single threaded, and it would be incredibly detrimental to them as a company if they did that.

Unfortunately, this time around who ever is making the engineering decisions at AMD decided to just focus on adding more cores. This would have been fine if each core was as powerful as Phenom 2 with much higher clock speeds. Instead we have a chip that is a lot slower clock for clock then a product they released 3 years ago.

Personally I am surprised that AMD would actually launch this product. They should have just announced that they are scrapping the AMD FX launch due to performance issues. Instead they would have been better off releasing a die shrink of Thuban and have an 8 core model. Better IPC, single thread performance, and similar power consumption. Then take what they learned from working on BD (high clock speeds possible, crap performance per core, high power consumption, etc.) and make a new architecture.

Bulldozer does have a purpose. It is an improvement over Phenom IIs. However that improvement won't come about for quite some time for most users.

You are right.

Not really, at least at current prices. The FX-4100 can't compete with a Phenom II X4 955 BE clock for clock, and it is even beaten in many benchmarks by the A8-3850. As to the FX-6100 it's more expensive than the Phenom II X6 1090T, and if the FX-8150 already struggles to beat the Thuban and loses in other cases, I can't imagine what happens in this case.

I'm sure there is a set of benchmarks already featuring the FX-4100 and FX-6100. If someone remembers which site did them, I'd be much appreciated.

That's just bad business sense. Yeah, you don't get butthurt by the reviews, but they've still spent a ton of money on it. I'm gonna pull random numbers out of my butt as an example. Let's say two months ago AMD was already $13m in the hole for Bulldozer and they had projected sales to only earn $10m. Now do you release and be short only $3m or scrap it and be down $13m.

If AMD focuses 100% on improving IPC and the chipset, intercore bandwidth and chipset performance their may still be hope for AMD. Dedicate themselves to an aggressive release cycle like intel. If AMD could improve IPC by 25% and implement their own version of hyper threading for each integer core, then AMD could be scary. Problem is they don't have the money or resources to make that happen.

Where's the benchmarks for the new Opteron 6200 CPUs? That's all I want to see.
