Test results for Intel's Sandy Bridge processor

Hi Agner - have you noticed that Turbo Boost is much more effective on Sandy Bridge than on Nehalem ? On a 4 core 3.4 GHz SB with all cores working flat out I'm seeing the clock speed staying at 4.3 GHz for 20+ minutes. This seems to suggest that there is 25% extra performance to be had for free, so long as you have sufficient cooling.
