Four more Sandy Bridge-EP processors from Intel’s soon-to-be-unveiled Xeon E5 product series have been recently spotted in some official documents published by Fujitsu and ASRock.

The chips were uncovered when a CPU-World reader came across the configuration page of the Fujitsu CELSIUS M720 system, which included the two Xeon E5-2600 SKUs that nobody had heard of before.

The processors are called the Xeon E5-1603 and E5-1607, and even though their specifications were lacking, CPU-World managed to find them on the ASRock website, mentioned in a CPU compatibility list for LGA 2011 SKUs.

The CPU support list contains specifications of Xeon E5-1603 and E5-1607, along with details on two members of E5-4600 series, dubbed the E5-4620 and E5-4650.

According to the information gathered, the Xeon E5-1603 and E5-1607 operate at 2.8GHz and 3GHz, respectively, while featuring four processing cores, a 130W TDP and 10MB of shared Level 3 cache memory.

Both of these processors are destined to be used in single-socket workstations and lack support for Hyper-Threading and Turbo Boost technologies.

The other chips uncovered, the E5-4620 and E5-4650 SKUs are aimed at 4-way servers and are supposed to launch in the second quarter of 2012.

According to the ASRock specs list, Xeon E5-4620 comes sporting a 2.2GHz clock speed, 16MB of L3 cache, and fits inside a 95 Watt TDP, while the Xeon E5-4650 is clocked at 2.7GHz, has 20MB of last level cache and a 130 Watt TDP.

Both CPUs are based on Intel's Sandy Bridge-EP architecture, and CPU-World suspects that the 4620 model will have either 6 or 8 CPU cores, while the 4650 Xeon E5 model will have 8 cores.

No further details are available at this point in time, but we’ll keep you up to date with how things evolve.
