Wow... looks like AMD might be coming out of the existing slump!
I think it's a step in the right direction, but I don't think it'll topple Intel's new nehalem server platform. The only thing amd can hope for is higher power efficiency and lower prices.
Honestly Istanbul is a step in a seemingly right direction, but I honestly think amd has yet to really tap the power of there quad cores -- and I think it has to do with there microcode more than anything else. If you compare the phenom arch. to the nehleam(sp?) arch. Aside from QPI vs HT theres not a lot of difference. The major hinderance you find is in the L3 cache's and throwing more cores at a problem is essentially masking it.
It's not custom unless your the only one who can boot it.
to be honest I would prefer to see an increase in performance per core rather then just throwing more cores on a single processor. While multicores has it's advantages how many applications really utilize more then 4 cores as it is.
The problem with adding more performance per core is that you have to program to it, where as if you just add more cores then the OS (which should be multi-thread aware in its scheduling algorithms) should be able to take advantage of all the cores without adding development work -- I think thats the idea behind "throwing hardware" at a perceived problem, not a great idea but a quick fix. I think as long as pricing stays reasonable (i.e. price vs performance), just like buying a 4-cylinder vs a straight-6/v6 would be then amd is on a seemingly productive track, they just have to fine tune it as I said above. Just my 2 cents....
true to a point if the multiple cores and share the workload or you come up with something like the smart cache technology.
Step in the right direction, we'll see the results soon enough.
