Intel Shows Off 8-Core, 128 Thread Nehalem-EX

By - Source: Tom's Hardware US | B 55 comments

This is big daddy Nehalem.

Intel yesterday previewed the next big, bad Xeon chip based on the latest 45nm high-k metal gate technology process, codenamed Nahelem-EX.

The Nehalem-EX chip features up to eight cores inside a single chip, and thanks to HyperThreading will support 16 threads. I’ll also pack an impressive 24 MB of cache.

Intel boasts that the “performance increase will be dramatic, posting the highest-ever jump from a previous generation processor,” with “up to nine times the memory bandwidth of the previous-generation Intel Xeon 7400 platform.”

The upcoming chip will also inherit reliability, availability and serviceability (RAS) features traditionally found in the Itanium processor family, such as Machine Check Architecture (MCA) Recovery.

Those looking to build serious servers out of the Nehalem-EX will be able to build systems that scale up to eight-sockets that are capable of processing 128 threads simultaneously.

Each CPU socket will also support 16 memory slots, doubling what was possible in the previous generation, and offer four high-bandwidth QuickPath Interconnect links.

Intel and IBM have provided a short introduction video showing off (very briefly) a server system running the aforementioned eight-socket, 128 thread setup.

Nehalem-EX is scheduled for production in the second half of 2009.

    I think this is a sloppy headline. The actual processor is 8 cores, 16 threads (double the current generation), and with multiple sockets, can become 128 threads (8 socket x 8 cores x 2 hyperthreads per core).

    Article seems a bit misleading -- isn't the new chip 8-core/16-thread, which in a 8-socket system would provide a 64-core/128-thread environment?

    Awesome. Just hope programmers learn how to harvest that much power.

    is it running at 100% all the time of the video? on the threads side i don't see the utilization of the CPU, while it shows 100% on the left side.

    Can it bruteforce =D?

    I could understand if the 8 core has 2HT for each core; that would make 16 threads simultaneously; but 128threads is rather... unbelievable...
    128threads are probably not for the average small business anymore

    dman3kOne quantum processor can make 3000 times more calculations in a single second than this load of crap! Too bad, no one is making quantum computers more affordable.

    They are not even in production yet as far as I am aware, still trying to get them to work so far!

    These guys do their job exceptionally well and bring us news about 8 core, it doesn't matter if their communication skills are lacking. :D

    Fairly land. It will be long, long, long time, if ever, before quantum computers replace traditional server/desktop/HPC CPU's. Nehalem EX, is awesome, and affordable and attainable this year.

    Yeah no doubt, soon as we have a (software) use for all these cores and threads, we'll be in business!

    ... who can afford it? Do GLOBAL economic crisis ring a bell??? So in a sense EDDIEROOLZ is right by asking:
    "But can it....
    run CRYSIS? :D "

    Ronald Demneriis it running at 100% all the time of the video? on the threads side i don't see the utilization of the CPU, while it shows 100% on the left side.


    The usage line on the graphs would have been on the very top edge of the graphs the whole time.
    So you'd have to be looking Really hard to see them.
