Tulsa: 1.3 billion transistors in a Xeon

Intel introduced the Tulsa processor, based on Intel's next-generation micro-architecture. The Tulsa processor is a dual core CPU, with a massive 16MB shared L3 cache totalling up 1.3 billion transistors on Intel's 65nm process.

Tulsa will work on the Bensley platform, which uses Intel's Blackford chipset.

The Blackford chipset features dual independent front-side buses offering 17GB/s of bandwidth to the two processors.

The Blackford chipset also features a 4-channel FB-DIMM memory controller, also offering 17GB/s of bandwidth to memory. The use of FB-DIMM technology has also allowed Intel to increase memory capacity on this chipset to 64GB.

The Bensley platform is already quite mature, with all of today's demos being run on Bensley with Dempsey CPUs. The most important point about Bensley is that it is compatible with both Dempsey and Woodcrest CPUs, meaning that a Bensley platform bought at the beginning of next year can accept the new Intel CPUs released at the end of next year without any hardware changes.

    A big deal was made over Microsoft Virtual Server's ability to move a virtual server to another physical box with no downtime. This is nothing new. Xen can alreay do this WITHOUT any special instruction extensions. As in, it can do it now, on any hardware.

    In addition, VMware's bluescreen demonstration is impressive until you realize that it too is nothing new; you can do the exact same thing on pretty much any virtualization solution, including older versions of VMware running on older hardware.

    Intel's virtualization technology is impressive because it is done at the hardware level, not because it was never done before. Read the last three paragraphs of this:


    So Vanderpool and Pacifica can efficiently run multiple, unmodified operating systems at the same time.

    The blue screen thingy was a proof-of-concept showing that the Intel chip was working.

    There’s a good point. It could be an attempt to help get the word out with multi OS server machines. I’ve witnessed a group load of server machines that aren’t cost efficient as a multi server setup. If I remember correctly (I haven’t checked out VMWARE lately), vmware required a host platform to operate properly and this appears to be their step up. I think it’s a great idea to run their setup without an initial host / parent.

    Changing processors improved the good hole hit rate from 20 to 70%
    Why ??
    Were the old processors getting the sums wrong?
    I can`t get my head round this.
    You`d think all ya needed was more time on old processors
    I`d appreciate enlightenment on this

    Yes, they were using the old Pentiums with error in FPU... (end sarcasm)
    I don't know for sure, but I think using processors that have more horsepower they can use more samples from previous holes. Some of these wells must be holed at a kilometer or more deep, and if one uses more sampling points in calculation, the results can be spectaculary better (or just as good, as this depends of lots of other factors).
    However, doubling the points might increase the computing load ten times or maybe more. So, the need for better computers.

    Nice, if you still have to exploit Iraq (end sarcasm).

    Will they have on chip memory controllers?
  • ceefka - Saturday, August 27, 2005 - link

    All I saw on my quick read were massive on die L2/3 memory: 4 - 16MB and they are holding on to Hyperthreading.

    All these Code names are making my heard hurt

    so true...i'm confused as all hell when I read about sossaman, and tulsa and whichmacallit...
