Today marks the arrival of the Xeon E3-1200 single socket processor with 17 more models coming soon for two, four, or even eight socket motherboards, though according to The Inquirer Intel has no plans to scale to 16 sockets.  They come in a bewildering array of models including the Sandy Bridge E we are used to, Sandy Bridge EN which uses LGA 1356 and is intended for dual CPU motherboards as it only has one QPI and the LGA 2011 Sandy Bridge EP which scales higher thanks to dual QPI.  No triple QPI but that may still be in store to reduce the number of hops in an 8+ socket board to 2 when used in symmetric multiprocessing in the future.

The E5-2400 (SB-EP) has eight cores and is targeted straight at AMD's lower price, lower power consumption chips as well as offering a noticeable improvement over the already launched E3s.  The E5-2600 family with its dual QPI is more suited for high powered applications that need several powerful processors working in tandem but not to the levels that the E7 series provides.  By offering such a wide variety of choices, especially a family of what for Intel are very low cost processors they are really putting a lot of pressure on AMD and the soon to be released Piledriver family.

"If you were planning on buying new servers in the coming weeks and months, Intel just gave you a whole lot of homework. And if you work at Advanced Micro Devices, you're getting some homework, too."
