It looks as though Intel may have a winner on its hands with Haswell when it comes to overclocking. One of the results in the CPU-Z database shows a Haswell CPU running at an impressive 7,012.65MHz. It's important to note that CPU-Z reported that the core was running four cores and four threads, suggesting that higher clocks could be achieved with a single core enabled.
Also interesting to note is the fact the BCLK was reported as 91.07MHz, suggesting that Haswell might scale better with a lower BCLK and higher multiplier. After all, Intel did increase the maximum multiplier to 77, which was used in achieving this impressive score.
As an overclocker, I can't wait to see what I can achieve with Haswell.
