AMD’s Jaguar Architecture: The CPU Powering Xbone, PS4, Kabini & Temash (2GHz clock speed requires 66% TDP increase compared to 1.6GHz)

Dissapointing, but expected. A 66% increase in TDP is pretty crazy for a 20% increase in clock speed. I guess these are intended to be used as LP chips after all.

I think now both will use 1.6Ghz for the CPU or at maximum 1.8Ghz... neither Sony or MS will go close to 2.0Ghz.

The article is largely an "I think.." article. Say hello to AMD data sheets that tell a different story. For example, the GX418RA module is a SoC that burns 15W at 1.8GHz (this is a quad-core Jaguar with disabled gpu). The GX420GA is a 2GHz Soc that burns 25W - that would be 66% more heat than the 1.6GHz SoC the article mentions, completely forgetting the gpu part since this 25W part is a SoC with ENABLED gpu.

If we add two of the 2GHz (no gpu) parts, we would end up in the 40W region for an 8core Jaguar. This is VERY EASILY coolable (mind you that 40W max is 8 cores fully busy doing porn downloads...). Of course 2 GHz parts are a lot more expensive than the normal 1.6GHz parts, as this is simply a fishing question for the best chips.

So technically, absolutely nothing speaks against a 2GHz 8core Jaguar SoC. Monetary wise, probably suicide at the moment. But you never know, since that 8G gddr5 bomb...
