I posted most of this in another thread, but I don't mind posting it here again.
The Prescotts will have 1 meg of L2 cache (Northwood P-4's have 512k). That by itself should help performance. They will also have SSE3 instructions. How much this will help (if at all) has yet to be seen, but I suspect there should be some efficiency improvements with the SSE3 realization.
How well the Prescotts overclocks is yet to be seen. I'm assuming they'll follow a similar path as previous cores. For example the Northwood when it was first released two years ago was hard pressed to O/C any higher than 2.5 to 2.6 gig. As the core matured and improvements were made, the overclocks got better and better. Within 6 months people were beginning to hitting 3 gig on air. New steppings were released and the overclocks climbed higher.
My prediction is the Prescotts will do the same. The budget minded folks might be smart to take advantage of the cheaper Northwoods and let the Prescott core mature a little and prices to drop before jumping in. For those of us that are adventurous and can afford it and like being pioneers, we will be happy to test out these new Prescotts and see what they'll do.
Sounds like Intel will release the Prescott on Feb 2 and then will have price drops on Feb 15. So waiting a couple weeks might save you a few bucks if you plan on buying a Prescott. The other thing to consider is that the second generation of Prescotts will follow fairly soon and this brings a new chipset and socket to the table.
Thanks for the reply, I am still undecided about waiting as I wanted to try out the Epox 4PDA2 ver 2 as it has lots of high voltages and I was hoping to get a 2.4c SL6Z3 to go with it if I can find one, but I also wanted to be able to use the prescot with the board but not sure if it will support it, but after reading your reply looks like we will be needing new boards in the future for the next generation prescot, I have seen all the reviews over at Xbit labs on there new chipsets etc very confusing at the moment hope that made sense thanks again.
Well there is this rule, "If its new of course they won't tell you about it til you buy it, oh yea and nothings backward capatiable." They always want you to buy more things so guess its going to result to actual testing if it will work in the mobo's or not.
Exactly - only motherboards conforming to the VRM 10.0 spec will support Prescott. A lot of mobo makers initially skimped on this requirement making their products incompatible with Prescott processors.
