So it seems to be good for multithreading, but what about multitasking? how does it do in that? There's only tests for the former?

I wonder if it's just an artifact of the benchmark? Something loosely analogous to a cpu benchmark of a gpu-bound game?
This is my understanding.

So it's a very niche processor that when it does produce good benches it's by a marginal increase from the competitors. But when it doesn't match up, it's significantly behind. NICE. AMD FTW!!

Correct. In fact, ALL Zambezi chips are the same die. The 4 cores and 6 cores are the same as the 8 core but with 1 or 2 modules disabled, and the 8120 and 8150 are clocked different (whether theyre binned or not I'm not sure though).

I wasn't aware that you know exactly what Intels future chips are like, can I borrow your time machine?

CMT could be the future, it might not be. But most of the problems relating to BD can be traced to other parts of the CPU (The decoder and cache) so we're yet to really see.

Of course, you won't listen and just say CMT sucks.

If in 3 years this new AMD architecture fails, they will have to design a new one. At the moment AMD pumps more cores and high clocks. INTEL pumped higher clocks and larger cache. To say with certainty that the BD arch will succeed is wishful thinking.
Because Prescott and Tejas was a pile of junk, if Prescott had been the same level of improvement over Northwood as Northwood was over Willamette we'd still have Netburst today.

But it got too leaky too fast, Intel probably could have fixed it with a new revision but it was far cheaper to go the Dothan/Conroe route.

Just like the 386, 486, Pentium, Pentium Pro and Pentium 4.

The only arguably completely new architecture that did well was Sandy Bridge.

the way that it functions in this alone would cause me to pick up BD.

I am very interested, and want to see someone put together some benches.

niche ?

photoshop cs 5 is niche ? it is de facto the tool with which graphics are developed for anything non 3d. ranging from website graphics to anything else 2d.

truecrypt ? niche ?

encryption is the order of the day. it is even being put into devices by default.

youre still off the encryption bandwagon ?

It's not really a niche product since it runs mainstream things just fine. What is your definition of a "niche product"?
