Intel Harpertown (Penryn) Quad CPUs Benchmarked 88

Posted by ScuttleMonkey from the we-have-the-technology dept.
unts writes "The Intel Developer Forum is currently running in San Francisco, and Intel is showing off the up-coming Harpertown processors based on the Penryn core. HEXUS got hands on with a test system and ran some performance tests: 'Harpertown is a better quad-core processor than Clovertown: it's as simple as that. More L2 cache will gobble-up larger application data-sets and a higher FSB, on select models, will ensure that per-CPU bandwidth is less of a concern.'"

      This is the "tick" to be followed by next years "tock"... the same basic core in a new process (45nm, which allows more room for cache, etc.) followed by next years new core that leverages the smaller process (45nm). In other words it has a "familiar ring" because it is essentially the same core. In 2008 (late likely) we will get on board memory controller... which doesn't have such a "familiar ring".

      There is a big difference. While L2 almost always helps (especially with the cores be so much faster than the memory bus), Intel's current designs end up in bus contention if you try to use them to much. While the Opteron's have their own memory controllers, all four cores on this chip have to go through the Northbridge to get to memory, so they have to share those two channels.

      It used to be even worse. When Intel was pulling the dual-dual core thing, to access one core was wicked quick, to access the othe

Cell would only be useful for batch numerical processing work of specific kinds (I'm guessing accounting would be bad, 3D rendering would work very well).

      The Niagra processor is a great idea for (web, db) server workloads, where you have a lot of inherent parallelism and very poor cache behavior. A while back, the Piranha research project figured out that for such types of applications, it's better to have many "wimpy", in-order cores than a few "beefy", out-of-order execution ones. Niagra is doing exactly this. However, outside this application realm Niagra doesn't do that well.

      Bottomline: The Niagra microarchitecture is meant for a particular niche.

    This article goes into some of the juicy technical details about Penryn/Nehalem and covers a lot of ground about what Intel had to show at the IDF.

    The article is also relevant to this discussion [slashdot.org], "End of Moore's Law in 10-15 years?". FTA:

    Otellini provided an overview of the history of the insulating layer which, in modern CPUs, is only five molecular layers of silicon dioxide (SiO2) thick. He explained that as far back as 15 years ago, Intels engineers saw this layer as problematic. The continued scaling of the insulating layer could not continue forever. And, we found out later in the day with Dr. Gordon Moores keynote, that five molecular layers is about the lowest you can go in practice. Its a form of wall, and Intel was right up against it.

    • Just make a regular die, deposit more silicon on top, put your second processor on top. Interconnect with through silicon vias. Repeat. Now we're scaling in 3 dimensions and Moore's law is safe for 50 years or more.

IF --and this is a big one for me [as someone who understands thermodynamics in the macro world not the micro world] -- a penetration (circuit connection) through the insulating layer doesn't just give one side of a chip a heat path that will basically just burn through the 2nd payer on the other side...

    Basically, intel releases a new architecture every 2 years and in between that they release a die shrink/derivative.

Next they will release a new architecture using 45nm (codename Nehalem), then they will release a die shrink of Nehalem using 32nm, and so on and so forth...

    Here's a quick rundown:

    2007: Die shrink of the Core 2 architecture from 65nm to 45nm
    2008: New architecture (code name Nehalem) released at 45nm

    2011: Die shrink of the Sandy Bridge architecture from 32nm to 22nm

I just benchmarked a dual-Quad-Xeon myself (Dell 2900) and I could not believe the poor results I got. One app running in the system can get up to around 3,500 MB/s. Put just two tasks running together (taskset'ed to different chips), and they will each get around 2,600 MB/s. From there on, total aggregate bandwidth tops at 5,200 MB/s and stays there, no matter how many simultaneous tasks you run (it will of course degrade if you run more than eight tasks, you get the point).
