Any direct comparisons of i7 skt1156 & skt1366 @same clockspeed & turbo boost off?

Clock for Clock comparisons of i7 skt1156 & skt1366 with turbo boost off?

What I'm trying to find, is direct comparisons of the i7 860 or 870 against the i7 920, but with turbo boost turned off (as it will skew the results as the turbo boost on the skt1156 i7 is more aggressive) and both processors running at the same clock speed (something like 3.4GHz would be good).

None of the comparisons I've read seem to show a direct comparison of each platform with the processors running at equal speeds and no turbo boost.
Also I would quite like to see the power draw of each platform as the skt1156 i7's will most likely need a voltage increase to attain that speed and as has been in some reviews they do start to use a lot of power when you overclock them.

It's pretty much identical.

Interesting...

So another words, Lynnfield isn't really any faster than Bloomfield (tri-channel memory doesn't make any difference, which we already knew) and Lynnfield still has lower power draw though not by that much when clockspeeds increase?

I was just trying to see if anyone had actually compared the platforms at equal clockspeeds (no turbo boost to skew things) to see what progress if any in terms of performance moving the PCI-E controller onto the CPU has made.

Leaving power consumption aside the only area I see that Lynnfield has progressed is memory performance/latencies which seem to be faster than Bloomfield, which should mean memory timings are now even more important than overall memory speed.

They should be pretty much identical aside from multi-GPU situations, the lower power consumption of Lynnfield is probably a result of the removal of the QPI bus.

Clock for clock, 1366 i7 is a little faster due to tri-channel memory but the difference isn't very large.

After yet more searching I found an article which pretty much backs up your statement.
Clock for Clock: Core i5, Core i7, Core 2 Quad and Phenom II X4 Performance

It even goes as far to say that if you plan on overclocking past 3.6GHz then no point getting the i7 8xx just get an i7 920 instead.
Very interesting read tbh.
