The New Xeon E7v3: The Same Xeon Haswell-EP Die...

The "new" Xeon E7 is basically the same Haswell EP die that we talked about in the our Xeon E5 reviews. Spot the only difference between the Haswell EP, 

and the Haswell EX die: 

Indeed, a third QPI link which allows an 8-socket configuration without any special glue logic. The transistor count is the same (5.69 Billion) and that is also true for the massive die size (662 mm²).

    They sure wouldn't lose the x86-64 license since they own it and Intel is licensing it from AMD.

    But without the license from Intel, it is worthless. There's also the question of how that works. I believe that Intel doesn't need to license back the 64 bit extensions.

    This one of the reasons why it would be in Intelsat best interest to let AMD be bought out with the 32 bit license intact. The 64 bit license/patents going to a third party that doesn't want to share would be a dooms day scenario for Intel. Legally it wouldn't affect anything currently on the market but it'd throw Intel's future roadmap into the trash.

    Pretty sure some regulatory bodies would step in if Intel were the only x86 game in town. And x86-64 is AMD property.

    Any patents on x86 are long expired, AMD only owns the IP related to the extension of the x86 not the instruction set.

    Not true. The U.S. government has them locked up under special military-based protections. Absolutely no one can make and sell x86 without Intel's and the DOD's permission.

    Got a source for that?

    I know that DoD did some validation on x86 many years ago. (The Pentium core used by Larrabee had the DoD changes incorporated.)

    hmm ... where's the RAS feature comparison/test ? did I miss it in the article ?

    In the E7v3 vs POWER comparison table, there should be 32 PCIe lanes instead 40 in the Xeon column.

    Additionally, it is the L3 in POWER8 that runs half of the core speed. L2 runs at the core speed.
