Are you sure about the Clovertown Xenons being slower? Here I looked at this link
Clovertown article
It had quotes like:
If you are using the BEA JVM, the Xeon is a much better choice than the AMD Opteron.
This cannot be a coincidence anymore: a single Xeon E5345 leaves the dual Opteron 880 far behind, but a dual Xeon E5345 trails the quad Opteron.
Four 2.4GHz Opteron cores are a bit slower than four 2.33GHz Xeons, but when we look at the eight core scores the Opteron is a bit faster.
But when you look at the numbers in the table, the Octa core Opteron is 1720 and the Octa Core Xeon 5345 is 1686
see second table the difference is on ~2-3% which exactly the difference in clock speed 2.4GHz vs 2.33GHz.
And is this quote in the "Analysis" section they call the Clovertown "a winner" and a huge step foward.
Thanks to the very competitive price, the new quad core Xeon is in many applications a winner when it comes to price/performance: a dual socket server is a lot cheaper than a quad socket model and a 2.33GHz quad core Xeon costs the same as a dual core Xeon 5160. Despite the very aggressive price setting and the excellent per socket performance, the newest Xeon is not unbeatable, a result of mediocre scaling.
So yes, there are applications out there where a "Clovertown" Xeon is a huge step forward.
To me the results looked pretty mixed. Sometime the 8 core Intel system was faster, sometime the 8 core AMD system was faster. However, if we assume these results are correct for a AMD chip that is faster than the Intel chip, then if we didn't try to compare apples to apples the new 3.0GHz Clovertowns should beat the 2.4GHz 880's. If I am reading it incorrectly, could you please clarify?
