New Intel Sandy Bridge-EP CPUs spotted
This quarter Intel plans to introduce Xeon E5-1600 products for uni-processor systems, based on Romley (socket 2011) platform. We originally reported on three E5-16xx quad-, 6- and 8-core models. Our reader Rob Dunkley spotted two new entry level Xeon E5 microprocessors, and complete list of Xeon E5-2600 SKUs, on Fujitsu CELSIUS M720 configuration page. Specifications on the configuration page are incomplete, but we were able to find more details elsewhere. Xeon E5-1603 and E5-1607 were briefly added to CPU support lists for ASRock socket 2011 motherboards. Information is already removed from ASRock website, however it is still available in Google cache:
The CPU support list contains specifications of Xeon E5-1603 and E5-1607, along with details on two members of E5-4600 series, E5-4620 and E5-4650. Characteristics of remaining E5 processors from the page match our older reports.
Based on data that we discovered, Xeon E5-1603 and E5-1607 operate at 2.8 GHz and 3 GHz respectively. The processors have 4 CPU cores, which can be found on other Fuhitsu-shop.pl pages (like this one). Both Xeons have 10 MB L3 cache, and 130 Watt Thermal Design Power. We suspect that similar to Xeon E5-240x and E5-260x products, E5-1603 and E5-1607 will not support Hyper-Threading and Turbo Boost technologies.
Xeon E5 4600-series is aimed at 4-way servers, and it is supposed to launch in Q2 2012. Last month Intel made public s-spec and box part numbers of E5-4600-series CPUs, although specifications of any of those chips were not known up until now. ASRock CPU support list provides partial details for E5-4620 and E5-4650 SKUs. Xeon E5-4620 comes with 2.2 GHz clock speed and 16 MB L3 cache, and it fits into 95 Watt thermal envelope. Xeon E5-4650 is clocked at 2.7 GHz, and has 20 MB last level cache and 130 Watt TDP. Both CPUs are based on Sandy Bridge-EP-8, and we suspect that the 4620 model will have either 6 or 8 CPU cores, and the 4650 will have 8 cores. We also believe that these Xeon E5s will support Hyper-Threading and Turbo Boost technologies.
Details of new E5-1600 and E5-4600 parts are summarized in the table below. Highlighted information is not confirmed:
