From what I've read, I believe the Crystalwell Haswell CPUs could be great for Rosetta due to the 128MB eDRAM which is essentially a large L4 cache, which should help keep the pipelines fuller than they could otherwise be. So that's anything with "Iris Pro 5200" (AKA "GT3e"), which is any i7 that ends "50HQ". There are three listed so far, with the slowest one not available until Q3: i7-4950HQ, i7-4850HQ & i7-4750HQ. The articles on these chips I've read only concentrate on the effect on graphics and GPU compute, with a bit of CPU compute in there, but nothing cache-heavy like Rosetta. Unfortunately, no socketed versions have been anounced yet - they're all soldered on BGA chips, apparently only for OEMs. Also, the Xbox One will have 32MB eDRAM - wonder how long it will take for someone to get Linux running on that :D Anyone know anything about these chips/boards or planning on getting one? |

I didn't think dell sold that kind? http://dealnews.com/Dell-XPS-Haswell-i7-Quad-3.4-GHz-PC-w-23-IPS-LCD-for-850-free-shipping/745020.html |

I also found a standalone version here: http://www.microcenter.com/single_product_results.aspx?sku=583369 |

Hi Mikey Your first link is a 4770 and your second is a 4770k - both are socket LGA1150 so neither have the eDRAM package. It's only the soldered BGA chips that I listed above that have the eDRAM package that been announced so far. |

Hi Mikey Ahhhh...I saw Haswell and 'assumed' ALL Haswell's were all the same. Sorry about that!! |

Hi Mikey Unfortunately not - it looks like all Haswell chips will be very good at crunching through Rosetta tasks, but I expect those with eDRAM will be the best by far... Hopefully they'll release a socketed version with eDRAM. Or AMD will come up with a Steamroller based equivalent pretty soon (seeing as they're already doing a Jaguar chip with eDRAM for the Xbox One). |

Hi Mikey On another project I saw someone say they thought the Xbox One could be dual bootable and therefore able to crunch. I think that may be wishful thinking, but I hope not. They thought the same thing for the new Sony system too. |
