This would be quite early samples from a new node -- it's normal.Whoah, another engineering sample that underperforms? Weird...
Very little, if any IPC changes. All about clocks and power. Also a better GPU, and perhaps better caches.Is Ivy Bridge supposed to bring any IPC improvement or will it all be in clocks?
Could IB get here before BD?

not unless BD gets delayed to next summer.Could IB get here before BD?
Is it also normal that it's a little slower on SuperPI than an i5 at the same speed? (Page 5.)
I would actually like to see such a development. There haven't been any large improvements in clock frequency for over 6 years, and tri-gate 22 nm, which as I understand it greatly reduces power leakage compared to what we have today, could make new increases in clock frequency possible.There has been speculation that SB was the last CPU designed for all out IPC performance. So it's possible it could be slower clock for clock with greatly improved efficiency.

How is the memory subsystem working? It's pretty common for some levels of cache to disabled on ES chips, or the memory controller being barely functional. Both would be disastrous for superPI performance.

Surely, Intel cannot think that a majority of their market is more concerned about power than speed, given the speeds and power consumption that SB already gives.
The majority of the Intel's market is the enterprise, and yes, we are very, very concerned about power. It's expensive to run tens of thousands of PCs, let alone the amount of power data centers suck down.
Besides, define speed. Is IPC the only way to achieve it?
Personally I'm a fan of constant IPC increases, it's the thing that makes all apps run faster.
It must be difficult for intel loyalists to reconcile how to idolize ivy bridge without improved IPC and higher clock speed, while critisizing bulldozer with improved IPC and higher clock speed. (according to current rumors)
