I imagine consistently 4GHz on a single thread with turbo. Obviously when you get up to the 16-core versions it'll be closer to 2.5GHz.

I mean the existing AMD 6-core "Thuban" can get to 4GHz with OC and still use a reasonable amount of power, and that's with the current design on a tweaked 45nm (new low-k dielectric layer). So 32nm and this pipeline should allow consumer products to turbo to there.

thanks for blowing my head up lol.

some new info... ish

22diggsdiggWe're live from the 2010 Intel Developer Forum in San Francisco, where we've got an interesting tidbit of news -- those long-awaited and often leaked Sandy Bridge processors will "begin shipping in very high volume" early next year in both laptop and desktop PCs. Now called the "2nd Generation Intel Core processors," the new chips will feature Intel's new 32nm architecture for everything, including the integrated graphics processor and memory controller, which will hopefully reduce their power consumption even as the new hardware's not terribly friendly to overclockers. PR after the break.

Update: Intel's on stage explaining a bit more about how Sandy Bridge works -- apparently the Turbo modes introduced in earlier Core chips (which dynamically clock individual processor cores based on how much thermal headroom they have) now works dynamically with the silicon's integrated graphics as well. Intel says it can actually exceed the TDP thermal envelope of a chip now to further overclock multiple cores at once, or switch off between overclocking graphics or CPU cores for differing workloads. See a few example images in the gallery below.

and yet another look at sandy bridge 

We are out at the Intel Developers Forum taking place in San Francisco over the next few days and just snapped a few interesting pictures of the company’s upcoming Sandy Bridge processor. What you see pictured here is a wafer of 32nm Sandy Bridge processors, the actual processor with its die exposed (sans heatspreader), and a motherboard to accommodate the chip.

We are currently at work detailing information released during the opening keynote at the show, but wanted to give you this quick glimpse of the hardware. As you can see in the images above, Sandy Bridge has a significantly smaller die than 45nm Nehalem, despite having integrated graphics. Also, the CPU and GPU reside on a single die, unlike Westmere which is sitting right next to Sandy Bridge, that utilizes a multi-chip module type package with discrete die for each component.

The motherboard on display appeared to be an upcoming enthusiast offering from Intel for Sandy Bridge, but the actual naming of the board wasn’t disclosed. In addition to the “extreme” color scheme, which Intel has been available from Intel for a while now on their enthusiast class motherboards, the mobo pictured here lacked any kind of display output. We assume this board is either an early engineering sample or it’s a board targeted at gamers who will most likely use discrete graphics. It features the upcoming 6-Series chipset for Sandry Bridge, which will have native support for SATA 6G, socket 1155, and USB 3.0 via an NEC controller. No native USB 3.0 on Intel chipsets for the immediate future.

Stay tuned to HotHardware for more coverage from IDF as the day and week progresses.

"2nd Generation Intel Core processors,"

I didn't know they were still using the "Core" name. 2nd generation Core sounds like the Core 2 which was before Nehalem...
