Intel Xeon E5 CPUs surfaced on Intel website

Forthcoming Intel Xeon E5 family will be separated into 4 subfamilies, based on intended market. Xeon E5-4600 will support up to 4-way servers, E5-2400 and E5-2600 will target 2-way servers and workstations, and E5-1600 series will work in uni-processor systems. In the past months we reported on details of E5-1600, E5-2400 and E5-2400 families, whereas model lineup of E5-4600 family was not known up to this moment. Today Intel added Xeon E5 box part numbers and S-spec numbers to Material Declaration Data Sheets (MDDS) database. This addition confirmed processor numbers of one- and two-way Xeon E5 chips, and revealed E5-4600 processor numbers:

According to MDDS database, Xeon E5-4600 series will consist of at least 8 models. Xeon E5-4603 will be based on Sandy-Bridge-EP-4 core, which means that it will have 4 or fewer cores. Remaining 7 processors, including low-power E5-4640L and E5-4650L CPUs, should have 6 or 8 cores. Xeon E5-4600 box part numbers, related processor numbers, and associated S-Spec codes are listed below:

Model number	Box part number	S-spec(s)
E5-4603	BX80621E54603	SR0LF
E5-4607	BX80621E54607	SR0KU / SR0JL
E5-4610	BX80621E54610	SR0KS / SR0JJ
E5-4620	BX80621E54620	SR0JP / SR0L4
E5-4640	BX80621E54640	SR0KT
E5-4640L	BX80621E54640L	SR0JK
E5-4650	BX80621E54650	SR0KJ
E5-4650L	BX80621E54650L	SR0L3 / SR0JN

The database lists only one chip from E5-1600 series: Xeon E5-1660 with box part number BX80621E51660, and two S-spec numbers SR0KN and SR0H2, perhaps with different core steppings. Two other E5-1600 SKUs, expected to launch this quarter, are E5-1620 and E5-1650.

The MDDS database has 7 SKUs from E5-2400 family. This list is incomplete, as it doesn't include 5 low-power Xeons from the series. These microprocessors will be available in Q2 2012. Model, s-spec and Box part numbers of standard-power processors are provided below:

Model number	Box part number	S-spec
E5-2403	BX80621E52403	SR0LS
E5-2407	BX80621E52407	SR0LR
E5-2420	BX80621E52420	SR0LN
E5-2430	BX80621E52430	SR0LM
E5-2440	BX80621E52440	SR0LK
E5-2450	BX80621E52450	SR0LJ
E5-2470	BX80621E52470	SR0LG

The list of boxed Xeon E5-2600 processors in the MDDS database matches exactly with the list, that we published in August 2011. These Xeon E5s will be released this quarter:

E5-2603	BX80621E52603	SR0LB
E5-2609	BX80621E52609	SR0LA
E5-2620	BX80621E52620	SR0H7 / SR0KW
E5-2630	BX80621E52630	SR0H6 / SR0KV
E5-2640	BX80621E52640	SR0H5 / SR0KR
E5-2650	BX80621E52650	SR0H4 / SR0KQ
E5-2660	BX80621E52660	SR0KK / SR0GZ
E5-2665	BX80621E52665	SR0L1 / SR0HB
E5-2667	BX80621E52667	SR0H3
E5-2670	BX80621E52670	SR0KX / SR0H8
E5-2680	BX80621E52680	SR0KH / SR0GY
