[dailytech] Dodeca-core: The Megahertz Race is Now Officially the Multi-core Race

AMD engineers reveal details about the company's upcoming 45nm processor roadmap, including plans for 12-core processors

"Shanghai! Shanghai!" the reporters cry during the AMD's financial analyst day today. Despite the fact that the company will lay off nearly 5% of its work force this week, followed by another 5% next month, most employees interviewed by DailyTech continue to convey an optimistic outlook.

The next major milestone for the CPU engineers comes late this year, with the debut of 45nm Shanghai. Shanghai, for all intents and purposes, is nearly identical to the B3 stepping of Socket 1207 Opteron (Barcelona) shipping today. However, where as Barcelona had its HyperTransport 3.0 clock generator fused off, Shanghai will once again attempt to get HT3.0 right.

Original roadmaps anticipated that HT3.0 would be used for socket-to-socket communication, but also for communication to the Southbridge controllers. Motherboard manufacturers have confirmed that this is no longer the case, and that HT3.0 will only be used for inter-CPU communication.

"Don't be disappointed, AMD is making up for it," hints one engineer. Further conversations revealed that inter-CPU communication is going to be a big deal with the 45nm refresh. The first breadcrumb comes with a new "native six-core" Shanghai derivative, currently codenamed Istanbul. This processor is clearly targeted at Intel's recently announced six-core, 45nm Dunnington processor.

But sextuple-core processors have been done, or at least we'll see the first ones this year. The real neat stuff comes a few months after, where AMD will finally ditch the "native-core" rhetoric. Two separate reports sent to DailyTech from AMD partners indicate that Shanghai and its derivatives will also get twin-die per package treatment.

AMD planned twin-die configurations as far back as the K8 architecture, though abandoned those efforts. The company never explained why those processors were nixed, but just weeks later "native quad-core" became a major marketing campaign for the AMD in anticipation of Barcelona.

A twin-die Istanbul processor could enable 12 cores in a single package. Each of these cores will communicate to each other via the now-enabled HT3.0 interconnect on the processor.

The rabbit hole gets deeper. Since each of these processors will contain a dual-channel memory controller, a single-core can emulate quad-channel memory functions by accessing the other dual-channel memory controller on the same socket. This move is likely a preemptive strike against Intel's Nehalem tri-channel memory controller.

Motherboard manufacturers claim Shanghai and its many-core derivatives will be backwards compatible with existing Socket 1207 motherboards. However, processor-to-processor communication will downgrade to lower HyperTransport frequencies on these older motherboards. The newest 1207+ motherboards will officially support the HyperTransport 3.0 frequencies.

Shanghai is currently taped out and running Windows at AMD.

Meh, Opteronz...

I want 12 cores in my desktop!!

So...is it going to be an Opertron? Or an Athlon?

Realistically there is no need for 12 cores on a desktop, so I would expect these to be Opterons targeted at servers. Heavily taxed servers could see huge benefits when upgrading to a 12 core proc even if they stick with their older 1207 boards.

Sounds like if you want 12 cores in your desktop in the future, your going to need a 1207 board. At that point is it still a desktop?

sounds more like you need a 1337 board. lulz.

(please God, forgive me for talking like that)
