It's time, pretty much right now, for me to buy a dual processor system. (something really huge would have to be coming for me to decide to wait, and I don't think it is...)
so the 800fsb Xeons will be infernos of brimstone and lava, and only one board exists that can take them and it can't be bought. And PCI Express will launch with a bunch of chips that already exist for AGP, and are going to be repackaged with AGP <-> Express bridges.
So I'm buying now. What CPU do I get? 1MB Xeons? 512KB Xeons? Or Opterons?
512 Xeons looks more attractive unless the 1MB xeons are more than 40% faster. The benchmarks I've seen for Opterons vs. 512kb Xeons show the Opterons being kicked to the curb in all the benchmarks that matter to me, which are:
IO Throughput, a.k.a. raid with >4 channels in RAID-0.
3D Rendering
JCLW told me in <A HREF="http://forumz.tomshardware.com/hardware/modules.php?name=Forums&file=viewtopic&p=556997#556997" target="_new">This Post</A> that I should look for Xeons whose part numbers start with an SL7, but I have no idea what that means, and I can't find any part numbers like this in online shops. They're all things like "INT-BX80532KE3066D".
So, can anyone support/refute that Xeons perform better than Opterons in the applications I already have, or link a benchmark they've seen for the 1MB Xeons vs. the 512KB xeons, or maybe shed some light on this part number thing?
Also, one thing's been bugging me: Since the new Xeons have hyperthreading, and each one is seen in windows XP as being two processors, can Windows XP support four processors? (two P4 Xeons will be like 4 processors to windows?)
