Oh no Hype-Threading is back :-(

8 fake cores at 60% speed or 4 real cores att 100% ? I'd take the 4 anyday unless it's for a server with tons of users.

Why ? Because there's nearly no software that scales well enough to actually get a net gain from those theoretical extra 20% of performance .

Also as you optimise code the software scales worse as there are less spare resources to Hype-Thread width which makes it a pita for the few of us who still know how to write good code.

Otherwise it seems nice and actually very similar to K8L or K10 or whatever it's called.

I had high hopes for the K10, but this just seems like a slaughter. AMD needs to come up with something that is at least *close* for a reduction in price. The 486 DX133 vs the iP75, K6 vs iPMMX and Barton vs Coppermine P4 spring to mind.

I really want to see what AMD has cooking. However, I think intel will be in my machine for quite some time.

I really hope that even the rabid Intel fanboys realize what a huge disaster it would be to have AMD pull back to a K6 era position. I still remember the two-three speed grades of Pentium per year and the horrifying price gouging that we endured (2000$ Xeons, anyone? At the LOW end?).

Please Gord, keep AMD alive and relevant.

Just a note, desktop and laptop versions will NOT have an IMC.

And the cache is still a shared L2, just 24way with other enchancements.

Yikes... a next-gen 45nm "Core 2" style architecture, plus all the stuff that allowed K8 to eat the P4 for lunch? I'm sorry to say, AMD is in danger of being left completely in the dust here. I hope they've got some tricks up their sleeve to keep things reasonably competitive.

It's unreal how quickly things are changing. But I'm holding on to my E6400 until at least the end of 2009 when I'll be looking at a new system again.
