Intel added the new high-end X5472 with a 1600MHz FSB and the X5450 with a 1333MHz FSB to its 45nm server lineup. Both CPUs run at 3.0GHz and feature 12MB L2 cache and a 120W TDP. The X5472 is priced at US$958 in 1000-unit tray quantities, while the X5450 is priced at US$851.
These are due to be released on Nov 12. This is more good news for "medium" sized SQL Server 2005 servers, since this will give you eight high-performance processor cores, backed by a large L2 cache and a faster FSB pathway to main memory. On top of this, 4GB sticks of RAM are finally becoming somewhat more price competitive with 2GB sticks of RAM.
Since Microsoft only charges per CPU socket for SQL Server processor licenses, this will let you build a very powerful two-socket SQL Server system for less money, which is always a good thing.
