Sandy Bridge versus Clarkdale (and Jasper Forest/Bloomfield/Lynnfield/Iron Lake)

[Idontcare]

Goto-san has been busy.

Really lousy dieshot of Sandy Bridge with layout highlighted

Still 8MB of cache for 4 cores. Yawn.

Sandy Bridge versus Bloomfield and Clarkdale with Iron Lake

Sandy diesize is 210-220mm^2, compared to 263mm^2 for bloomfield and 296mm^2 for lynnfield. Clarkdale is figured to be ~79mm^2 by Goto-san.

Sandy Bridge versus Clarkdale with CPU Core comparisons

Westmere core is 17mm^2, compared to 29mm^2 for bloomfield cores. In contrast Sandy Bridge cores are 19mm^2.

Sandy Bridge is to have an enhanced dynamic clocking feature-set, turbo modes will be temperature aware and allow for exceeding TDP when the ambient is cooler (office environments with controlled A/C) and if the cpu was cold recently (<1min prior, allowing for "bursts" of turbo clocks).

That could really turn out to favor the water-cooling guys.

so when should i expect a PM from ya?

LOL....

That still doesn't matter for the real water cooling OCers though. They'll likely exceed the thermal limit and try to reach circuitry related limit. The presentation also says the maximum will be 37%, which is far lower than high end overclocks.

Maybe not great for high end overclocks, but for the rest of us with 120mm TowerFans it might be a good way to reach the limits of air cooling.

Couple of notes from the PCWatch article:

-Banias was a mobile focused part. It was designed from beginning to end for mobile. Core MA was the same, except they switched the focus to desktop and server in the middle of development(In contrast to Nehalem. The focus was for server, with design modularity to fit multiple market segments)
-Unlike Core MA, Sandy Bridge will focus on Mobile and Desktop, with lesser focus on server, all the way from beginning
-Sandy Bridge will be even more modular than Nehalem. Expect to see dual core versions with 150mm2 die.
-Quad core won't be mainstream for mobile Sandy Bridge and remain a niche. There will be no ULV quad core parts(just dual core), and dual cores will still be mainstream in mobile.

I want an LV mobile quad core with like 25W TDP (12-13" dell platform).
Oh well, I plan on arrandale->ivy, not arrandale->sandy->ivy for mobile. Tick for mobile, Tock for gaming.
