As many people were intersted in the new Xeon MP processor here is the breaking news of the new core for them.....up to 2GHz with 2 MB of L3:

The Intel Xeon processor MP at 2 GHz with 2.0MB of integrated L3 cache is available for Intel's suggested list price of $3 692 in 1 000-unit quantities. The Intel Xeon processor MP at 1.90GHz with 1MB of integrated L3 cache and the Intel Xeon processor MP at 1.50GHz with 1MB of integrated L3 cache are available for the suggested list prices of $1 980 and $1 177 in 1 000-unit quantities, respectively. Intel expects OEM and channel distributors to ship systems based on the new processor in the coming weeks, the first companies to adopt the novelty will be HP, Dell and IBM.

Are they expensive or what :D......

I just wonder how much for a Xeon MP compilant mobo in this days.

WOW!!! That is redic. IMHO... I think they should price them around $50-100 for the crunchers out there:D

Crazy considering it's just a P4 with more cache and hyperthreading turned on - oh and they let you use more than 1.

The DP is more like the P4. The MP architecture is a bit of a departure. The DP will let you use more than 1, the MP lets you use more than 2.

From what I've read (and I could be wrong) the MP is a P4 core with more cache and the ability to work with a chipset that can handle 2 or more cpu's. The DP is just a regular P4 that is allowed to run in SMP mode with 2 cpu's max. Essentially Intel is charging big bucks for the extra cache and ability to use more than 2 cpu's. It's certainly a return to the good old Xeon days.

The MP core design is P4 based, but significantly different.
...but when have you known Intel to not charge as much as they possibly can. If you feel insulted by MP pricing, look into purchasing Itanium. ;)

Intel's prefetch problem continues

In the DP chips

By INQUIRER staff: Friday 08 November 2002, 10:31

CHIP GIANT INTEL quietly introduced its Gallatin processors on November the 4th, with Compaq introducing an eight processor DL760 and IBM another model in its x440 series using the chips.

But it looks as if the Intel engineers went back to their Northwood database and built these chips using this model, as the stepping is A0 and the model number has switched from one to two.

Will hyperthreading work on these chips?

But there's an errata list for these processors, in a specification update with erratum number 037, the prefetch bug, still existing in these parts, even though it was fixed in the Xeon Pentium 4 DP chips.

IBM is being smart by using its own proprietary L4 technique where the processor talks to a large cache and cache talks to the real memory.

Trouble is, that involves an extra cost, so the rest of the server industry appears not to wish to follow the IBM lead. µ

Most server mfrs. were looking to the larger cached CPU's to allow them to move beyond 4 CPU's without impacting performance. The P4 architecture is so impacted by memory performance that 8-way PIII Xeons will outperform 8-way P4 Xeons. The larger caches allow them to offset memory contention. IBM may have found a way to cope, but who really wants to get locked into IBM proprietary technology?
