Not a Sandy Bridge user atm--but I have an interesting observation for Sandy Bridge when it comes to LinX (since there's so many LinX results in this thread). It seems that it has a negligible, if negative performance difference per clock from Core 2 Duo.
Looking at leeghoofd's example of ~56GFLOPS at ~3GB problem size and 4.5GHz, that's a 25.8% advantage over a Core 2 Quad Q6600 with 44.5GFLOPs at ~3GB problem size and 3.4GHz.
A 25.8% advantage is significant but 4.5GHz is a 34% higher than 3.4GHz.
It could be an HT On/Off Issue
