Hi Michael,

We see a few eembc (mp2decode on SLM) and coremark regressions of the order of around 3-6%, and a couple of 3-6% geekbench (HSW) regression which we can follow up on.

In addition to this, we see significant (60%+) gains in denbench/rgb tests on HSW, which are nice.

Performance-wise, I think the change looks good to us.

I can give you (or anyone else) more specific on the gains/regressions if interested.

Thanks,
Zia.
