    Intel Pledges 80 Cores in Five Years

    SAN FRANCISCO--Intel has built a prototype of a processor with 80 cores that can perform a trillion floating-point operations per second.
    Imagine the fun you can have with the type of concurrency involved with these cores. Kidding! Assuming this actually ships (it might not), I imagine this would pretty much put the Windows division into a tailspin.

    mmm... 80 instances of Seti@home

    I don't read /. but I saw it in my feed reader already.

    Sounds like fun to me.

    Let's just hope they can make a BUS to support these...

    Perheps they'll just implement some sort of BUS inside the CPU for those cores to communicate, and each core will have 16MB cache... just like a "computer inside computer"... and the cores should have low utilization all the time...

    Btw, Why does it say 80 and not 64? I thought these "core numbers" ought to be the power of two...

    Not necessarily - if the Xbox 360 can have 3 cores, why can't intel make 80?

    80 Cores! Really!

    The serious issue is going to be IO bandwidth, a 1 Ghz bus isn't going to cut it.

    If these machines can be produced cheaply ... then I predict the mainframe will finally die.

    The mainframe is already dead (well, should be dead, if it weren't for Baby-boomer aged devvies who can't face losing their precious COBOL), we've got Beowulf and Cluster Computing, there's no need for monolithic dinosaurs anymore.

    Definitely. Currently, Windows uses a word-sized bitmask for processor affinity, meaning 32 bit Windows can technically support at most 32 logical processors, and 64 bit Windows at most 64. Currently, the only edition that actually supports the maximum number is Datacenter Edition.

    Bankers are still counting ROI on big iron and laughing at us.

    But I otherwise agree completely.


    Will these 80 cores be firing lasers at each other or just melting copper slowly under a light-wieght oil?
