[I]The wait is over. Seven years (almost to the day) after Intel and Hewlett-Packard first announced their partnership, Itanium systems are ready to roll off production lines.
This is the day Sun Microsystems has been dreading. Through all the years of Itanium hype, missteps and delays, Sun has touted its message of software compatibility while spreading fear and doubt about Itanium.
Now Itanium is here, and it isn't going away. Over the next several months, at least 20 vendors will introduce Itanium systems. Intel's investment in the Itanium family continues, with six new versions in the works.[/I]
**********
I expect Itanium to replace Xeon, but not until 2003, when McKinley and its successors open a performance gap over Xeon. The Itanium chips also offer 64-bit addressing and other features Xeon lacks.
**********
Changes in servers never happen fast. But with Itanium now a reality, Intel's dominance is only a matter of time.

"Érdekes lesz az 32nm, mert helyből 4x több tranzisztort pakolhatnak ugyanakkora felületre, ez a Tukwila fényében akár 8 milliárdot is jelenthet és akár 16 magot."
Nem egeszen mert a skalazodas nem linearis. A logikai aramkorok kb. 0.7 az SRAM pedig kb. 0.5 szorzoval skalazodik a node-ok kozott. A Tukwila-nal a terulet kb. 30%-a cache, tahat a szamok valahogy igy neznek ki 65->45->32nm valtasoknal:
Cache:
210mm2 -> 147mm2 -> 103mm2
Logic:
490mm2 -> 343mm2 -> 240mm2Ugyanaz a tranzisztor mennyiseg kb. fele annyi teruletet foglal 32nm-en, tehat ha tartani akarnak magukat a 700mm2 merethez akkor max 4-5 milliard fer el.
