So, I'm confused looking at the charts there- is the i5 actually the successor to the i7 or a cheaper counterpart? If it's the cheaper counterpart, it's doing a fine job, because it's beating the i7 in a number of tests.

In the benchmarks I've seen it's generally behind the i7 870, ahead of the i7 920 on single-threaded tasks and behind the i7 920 on multithreaded.
Note that you can't directly compare the Intel i5 results to the i7 results in this article because they're using a different BIOS. I'll be interested to see how they do compare once Phoronix has the same configuration.

Hmm their apache benchmark results are much lower than mine, can it be that ext4 is slower than ext3 here? Or is it the Intels SSD beeing lower than the OCZ vertex?
Also their stream results are lower, i used DDR3 1333 CL7 dunno what intel used.
Their EIST and Turbo off results are all much lower than mine, as if they ran at sub 2.66GHz.
Beside that turbo on results look valid.

justapost, what sort of cooling are you using? Curious about this turbo thing with the stock cooler in a closed case. Intel sending out monster coolers in the review kits is kind of questionable too, says to me "hey our stock cooling is crap, you'll have to buy something better if you want results like you see here".

2.66GHz 2.80GHz 2.80GHz 3.20GHz 3.20GHz
So it should never happen to have benchmark that produce double performance improvement from just having turbo enabled since from stock to the maximum turbo scaling possible is about 30% increase in clock speed.

Kano that's not right for Lynnfield. There's this table on Anandtech detailing Lynnfield's turbo modes.
