I'm putting together a new server. I'm looking at the Xeon E3-1270 processor. I see that the the new ivy bridge line is coming out next week. The ivy bridge version of this chip will be called Xeon E3-1270 v2 and it has the same socket. Will the new E3-1270 v2 work with existing motherboards that are designed for the E3-1270? (I'm looking at the SuperMicro X9SCM-F)
According to sources such as Anandtech, Ivy Bridge will be backwards compatible with Sandy Bridge-based motherboards.
Traditionally, Intel have featured backwards compatibility within each tick-tock cycle, and evidence points out this time it should be the same.
However, with the new Tri-Gate technology, and servers being a different class of machines, while there is a high chance it will be compatible (albeit maybe with lacking features), there is still a small chance it won't be compatible.
Ivy Bridge server class processors are not due out next week - their desktop processors are. According to Hardmac, there's a chance that Ivy Bridge Xeons will be delayed.
