yeah but intel will have some issues with the chips, the first one the Pentium X/EE will have HT technology enabled, but windows isn’t very good a schedualing more then two threads to be run at a time, for is just too much for it.
The chips will be hot, two prescotts joined together, that means a new all copper heatsync needs to be used, the current LGA775 Heat synce is huge, I built two LGA775 systems about two weeks ago, they actually don’t run too hot but i guess they could be cooler but oh well…
there is a bandwidth issue since not all of the dual core chips will be getting 1066Mhz FSBs, this may not be a problem if the number of “lanes” between the chip and northbridge is doubled, creating something like dual channel memory interleve, then we would need double doual channel interleve to get around a memory bottle neck, or maybe 800Mhz DDR2 would do the trick in a doual channel interleve mode. Then we’ll need to have a dual channel interleve sata raid interface thingy to eliminate a bottleneck there, then we’ll need to get more pci-express lanes, so that we can have two video cards in at the same time, in a SLI simmular interface, but both cards getting a full 16 lanes each, instead of 8 lanes each in the Nvidia SLI spec.
Then the only noticable preformance differenc will only be seen in apps that make use of multi threading programs. with 2 cores you get twice the ammound of bandwidth for the same speed (Ghz) and slightly higer latencies, which the Prescotts are nitorisous for a long execution pipeline and slightly higher ‘lag’ then AMD processors, to reach about an effictive double in performance, but not necessarily.
Still I plan on building a dual core, fully decked out system somethime next year. Two WD raptors 74GB 10,000RPM (the next gen ones comming out later this year with native command queing) and dual channel DDR2, best PCI Express graphics card avalible, Creative Labs Audigy 2 ZS Platnium, possibly a PCI Express version if avalible at the time that i build the box, best Gigabyte mb money can buy, and the list goes on. It’ll tie me over with one upgrade for most of my time in college.
