Well, prescotts are a PITA to cool with the stock heatsink, and without a ridiculous monstrosity, they will overheat!! The minimum I’d recommend with the dual core P4 is a Zalman 7700, or XP 90. That’s an extra $50 on the price of the chip right there! The power consumption isn’t a matter of the electric bill being high. It’s about the system needing more current on the 12v rail, and extra cooling, nothing more. It remains to be seen about how this will affect the lifespan of theese chips, but I have my suspicions. The dual cores are going to be worse. If you look at the performance:$$$ ratio, the dual core AMDs are going to smoke the P4s. The highest clock speed you can get is 3.2 ghz :Z from intel that has dual cores. The 2.8 is worth while, but it’s not going to be anything like a 4400+ with 1MB cache!!! While the higher end intel chips do a little better than the AMDs at video encoding, the difference is marginal at best. In your own link, the dual core AMD beats the P4 dual core!!! The difference is so small, its not worth quibbling over. I’d hardly call that a spanking. I changed my mind about getting the bottom end AMD chip, I’d go for the 4400+ with 1mb cache. That extra cache is worth it. The price is kinda high for the AMDs right now, but it will fall a little.
If you did go Intel, you should go DDR 2, and the new 955xe chipset. I dunno if you can even go dual core with DDR, I’d have to look into that. That’s going to add some $$$ right there. I’d get the 2.8ghz P4, the others are over priced. It’s still not going to perform as good as the AMD dual core, even for video encoding, but it will hold it’s own. You should have quite a bit of headroom for overclocking, but on air cooling that might not be easy with a dual core prescott. Also, good old intel decided to make it so the PCI express bus isn’t exactly lockable, so things could get ugly there. Mobo manufacturers have that problem sorta fixed, but it’s still not locked. You’ll have a cap on your OC because of this, and I’m not thinking this guy is going to want to OC at all. By the time you factor in DDR 2, the increased PSU requirements, and extra cooling for worse performance, I think AMD shines.
:Z :Z :Z
Now let’s go AMD dual core. Say the 4400+ for $580, and DDR. You’ll have saved about 30% on ram, because DDR is dirt cheap. You can get a gig of decent stuff for $100, for ddr2 you’re looking at $150 minimum. Now, I’m pretty sure you’re FORCED into the 955 chipset with an intel dual core, because good old intel decided to hose it’s customers yet again with no support for it on earlier chipsets! The cheapest 955 chipset mobos are 200+, close to $300!!! The Nforce4 mobos can be had for about $150 if you don’t want SLI, in fact the DFI is $140! If that doesn’t quite make the price equal, let’s look at the power issue, the AMD chips aren’t that mcuh better, but I’d still say you’re looking @ 20w extra for intel, which may or may not be the determining factor of which PSU you get! At a minimum, you’re looking @ $200 extra for the stuff needed to run the intel chip. That puts the difference of owning an AMD dual core puter, MAYBE $100 more. That is well worth it IMHO, and the only reason I’m saying to go that route.
AMD or intel dual core isn’t going to matter much either way. Especially for this, but I’m not going to argue my point any more. I think I’ve proven that the intel dual core solution isn’t really any cheaper, it certainly isn’t better, and it’s not a big enough difference to quibble about!!!
