Lynnfield overclocks to 5GHz
Author: Tim SmalleyPublished: 3rd June 2009
Sources at Taiwanese motherboard manufacturers say initial overclocking tests have been somewhat surprising.
Intel has remained mum on Lynnfield’s details, but its partners are very keen to talk about it. The Turbo mode, which dynamically adjusts the CPU frequency to deliver the maximum performance for the given thermal design power, will “add something north of 500MHz” to the CPU’s default clock speed in single threaded applications said an Intel spokesperson.
Our sources indicated that you are, in fact, likely to see an extra 600MHz for free in single threaded apps. This means the rumoured high-end 3.2GHz Lynnfield chip will hum along at 3.8GHz in some workloads, which is much more than the current Core i7 processors, which get an extra 200MHz or so for free when there’s power to spare.
This obviously means great things for overclocking and contrary to other reports we’ve read on the ‘net, it looks like Lynnfield is going to hit those 1GHz+ overclocks we’ve seen on the current Core i7 chips because 5GHz is “easily achievable,” said one source. Another said that they’d hit 5GHz “with very little effort,” which could make for some exciting times if you’re a cost-conscious enthusiast.
Obviously, we’ll reserve our final judgement until we’ve looked at how retail CPUs are overclocking, but these early whispers are looking promising.

I will be waiting in anticipation for Bit-Tech's review :D
This all sounds very wonderful, but if they're ES chips, means bugger all. Show me retail available chips doing this without breaking a sweat (and not getting close to their thermal limit) and I'll think about getting enthusiastic.
i5 and i7 are completely different in terms of interconnection with the rest of the components in the motherboard.
IMAO, the i5's biggest limitation is the number of PCIe lanes that come from the CPU directly (20?). Of course that this isn't a problem for the majority of consumers (you can split 16 lanes across two PEG slots). So apparently the i7 is for workstations (that don't need ECC RAM?) and enthusiasts (like the Skulltrail was, only this time is cheaper and less power hungry, I think)...
BTW socket 1156 has different mounting holes than 775 AND 1366 - what a ripoff!
I for one think that Intel has screwed us over with yet another one of their temporary solutions just to buy themselves enough time to create the "real" solution. I will stick to my overclocked Q6700 until i5 comes out.
I'm not sure Intel screwed us over, Core i7 was never intended to be a real desktop superstar. It's a workstation part through and through.
It's released for those of us that care enough to cater to our ePeen addiction, but aside from that they kept working on pricing and refreshing their 775 lineup. It's been clear from the start that 1366 was never meant to replace 775, that is the task of the 1156. From these early reports, and based on what Anand recently published, that will be done pretty well. A 5GHz quad will do very well, thanks very much
I lol'd.
:P

Just in case i win the lottery.

IT COULD HAPPEN.
The first Nehalem generation processor designs already exist. They are intended for use in server systems. Bloomfield processors and Gainestown LGA 1366 will appear in the fourth quarter 2008. The first samples of Lynnfield and Havendale processors LGA 1160 will appear in the third quarter 2008, mass production will be deployed in the first half 2009, and the announcement will be closer to mid-year 2009. 8 Core Nehalem generation processors will be presented in the server segment in the second half year 2009. They will be produced in 45 nm technology, the TDP will be limited to the value of 130 Watts.
That, I didn't know. That's really stupid.... :(
Yep, I'll also upgrade to i5... I simply don't need more than 20 PCIe lanes on my system.
However, I won't upgrade until the TDP drops... I'll probably upgrade first to a 9550S (only has 65W) if the prices drop (I have a 6600 right now).
for multi-socket i5, i don't think it's doable, Quickpath is what's used in these i* CPUs, and i think it's been used up internally to the PCIe bridge inside the CPU.
Im wondering though, if i5, which is supposedly intels new higher/mid range platform, can reach similar clocks and performance as the i7's which are the enthusiast (read: nerd's) platform at a lower cost, what incentive will there be for consumers to buy the i7?
