AMD has rethought its roadmap and, given its limited resources and its near-death experience with Barcelona, is scrubbing Montreal, the eight-core chip that was supposed to follow Shanghai, the chip after Barcelona, and substituting a six-core part code named Istanbul followed by a 12-core part called Magny-Cours in the first half of 2010.
Speculation has also been rife this week that AMD would finally tease out its so-called asset-lite manufacturing plans, thought to be some kind of cost-saving outsourcing scheme, at its shareholders meeting Thursday, chatter that has flamed into speculation that it will break in two – a manufacturing business and a chip design and development operation.
We hear it won’t have anything to say on either asset-lite, a notion AMD CEO Hector Ruiz first dangled without explaining a year ago, or any restructuring tomorrow.
Anyway, both of the new chips will use the same core as the hard-won
Magny-Cours will be Montreal-like but using native six-cores.
AMD did not disclose how the Magny-Cours cores would be linked. It is supposed to have 12MB of L3 cache.
There is also another six-core chip on the roadmap called
Chip groupie Nathan Brookwood said AMD was now trying to be conservative and, given the technology-induced delays with
AMD “won’t have performance leadership,” he said, “but it should manage to stay within shooting range of Intel depending on how good Intel’s Nehalem microarchitecture turns out to be. It’s still an unknown.”
Nehalem should be good for eight or more cores. Intel is already supposed to have six-core chip code named Dunnington ready in the second half of this year, a year ahead of AMD’s plans.
Apparently the eight-core
The 12-core part will run slower than the six-core. Parallel workloads are more likely to take advantage of it.
