Dual Opterons vs. Dual Xeons in SQL

[Glavinsolo]

SQL does per processor licensing. Xeons have HT enabled. So I have 3 options

2 Opterons = 2 processors
2 Xeons = 4 processors
2 Xeons HT disabled = 2 processors

Can someone post in a reply actual performance graphs of all three of these setups?

With SQL as a benchmark.

A link would also be nice but it may be blocked.

Thanks

Note that the Xeons are on a shared bus, both processors use the same memory bus, that why Xeons don't scale well. ie dual xeons use 1/2 the bus , while quad xeons use 1/4 the bus.

My recomendation is get dual or quad opterons with 2-4gigs of memory for each processor depending on your budget.

How about This Anandtech bench of Opteron 250's VS the NEW 3.6 noconas ? They really kick a$$. The noconas can;t compete in server stuff due to their handicapped memory bandwidth compared to the opterons.

The Opteron is tough in MySQL Most the server side performance stuff I've read, especially in 64bit seems to favor Opteron.

SQL charges fees per processor, even if that 'processor' is a logical processor from HT? Thats kinda fvcked up.

For sure, 2 Opterons is the Choice! :beer:

hyperthreading doesnt make a cpu act as 2 processors. it only allows for better multi-tasking, but is no where near dual cpu's.

I'm pretty sure a hyperthreaded CPU is considered a "single" CPU for SQL Server licensing purposes. In fact, didn't Microsoft recently announce that they would even consider the pending dual-core chips "single" CPU's for licensing purposes?

You are correct Sonoran MS SQL is going to be a one package=1cpu deal, at least for now. That being said, the poster didn't say which commercial SQl server he was using.

The Opteron deals out a decisive blow to the Xeons in MySQL. We know from past experiences that when you run extremely complicated SQL statements, the Opterons were a lot faster. After this project, we also know that the Opteron is still the winner when you mix a lot of simple queries with a few heavier queries.
