Link? Prescott chipsets are coming out in the first half of 2003 . Wouldnt that mean that the cpu would come out soon after?
Prescott is due in the second half of 2003, not the first half.

PRESCOTT
-Socket mPGA478
-Pentium 4 .09um 4GHz-6Ghz
-800Mhz FSB (200 quad pumped)
-1MB L2 Full speed cache
-32-bit ALUs Full speed
-Dual channel DDR-II 400Mhz
-Hyperthreading (More advanced Ver.)
-Advanced hardware data prefetch.
According to Intel Prescott will look like the following:
1. .09-micron die shrink from .13-micron "Northwood" core.
2. Additional unspecified micro-architectural enhancements.
3. Hyper-Threading Enabled.
.09-micron P4's by themselves will yield more frequency increases and will run cooler at the same clock speed compared to .13-micron P4's. Performance will hardly be any different between, lets say, a 3.5GHz Northwood (.13-micron) and 3.5GHz Prescott (.09-micron)
if all Prescott will be is a die shrink, but it's obviously going to be more than that.
I haven't once heard of a more "advanced version" of Hyper-Threading before. Do you have any info on this that we might be able to look at.
From reading the net, it seems like HT might or might not increase performance for Joe Average-type apps. Remember that HyperTreading is highly dependent on what application you're using, and in fact some apps actually will perform
worse when HyperThreading is enabled. Prelimary results from web sites like AnandTech and others seem to indicate that HT will mostly gain an advantage in workstation/low-end server type apps, not Joe Average OEM situations (you know what I'm talking about, a little gaming, some web surfing, DVD's, mp3's; those types of Joe Average apps).
An 800MHz FSB Prescott is speculation at this point (Anand mentioned this 800MHz figure in one of his IDF articles in late February). Since Anand's speculation though, I've seen 666MHz FSB a few times on "unofficial" Intel roadmaps (166.666... * 4 = 666.666...MHz FSB).
32-bit ALU's is also speculation. To be honest I don't know how much of an improvement 32-bit ALU's will yield over 16-bit ALU's.
1MB of L2 cache is certainly possible, and actually pretty likely IMHO. Intel has lots and lots of capacity. Even though they'll get fewer CPU's per wafer than if they were to go with a 512K L2 cache, I bet they'll still be able to supply enough Pentium 4 processors to their OEM and corporate partners with Prescott (although so much can happen a year from now...).
If Prescott actually does actually debut with DDR-II support (meaning there would have to be sufficient supplies of DDR-II on the market) then I can guarantee you that Prescott will be delayed to sometime in 2004. DDR-II isn't expected to yield any type of major (or even minor) production in 2003. Prescott will likely just support DDR333 if it debuts sometime between July and December (which is considered "2nd Half" of 2003).
