You mean they no longer have? I don't agree with that. Atleast not when talking about the chips commonly available for a reasonable price today. But I do agree that the Opterons are getting dated. The AM2 opterons are better in some respects, but from what I've heard there is more to come in later revisions. Reversed-HT (HyperThreading) for example is one thing I look forward to testing. Instead of Intel's HT where one cpu looks like two, amds dual-core cpus can look like one cpu to the process. So programs/games that are single-threaded or just not multithreaded good enough can benefit since several cores on the same cpu can cooperate on the same tasks. Whether this will have a great impact I don't know, but I think it'll have a bigger impact than HT did. HT was good for when a single-threaded process used 100% cpu; you could still do other things without major lag. Reverse HT should benefit regular office users more than servers I guess, and old single-threaded games probably. > While memory bandwidth plays a part in that, a lot of > that can be contributed to other factors as well such as the latency > advantage of the on die controller and shorter pipeline, etc. Completely different design than the P4 went for, unfortunately for Intel they didn't foresee the fact that they could not go past 4Ghz. Expensive fault, but it surely has thought them a valuable lesson. > Friend on mine works on a render farm for a movie studio.

I have not tried the new Intel chips, but surely they should be a lot better. Intel has had a lot of foul-ups now so it's about time they deliver something that has a good design from the start. Btw, Intel makes the best Network cards. Unless you need myrinet or something like that, but that costs a great deal more too. -HK _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
