Intel Discusses 15-core Ivytown Processor for Servers

Ivytown will slip into Intel's Xeon E7 chip family

Intel's codenames for processors sound like directions someone might give you if you get lost in the country. Take a wrong turn off of I64 in West Virginia, for example, and you might be told that Ivytown is on the other side of Ivy Bridge, not to be confused with Sandy Bridge. In reality, Ivytown is Intel's codename for an upcoming 15-core Xeon processor based on Ivy Bridge and designed for high-end servers.

Intel shared a few more details about Ivytown at the International Solid State Circuits Conference (ISSCC) in San Francisco this week. The Santa Clara chip maker said Ivytown will be part of its Xeon E7 lineup, which it's likely to formally introduce next week, PCWorld reports .

The Ivytown part is packing 4.31 billion transistors and has the most cores of any Intel x86 server CPU. Intel says it will likely be its fastest performing CPU for servers with frequencies ranging from 1.4GHz to 3.8GHz, drawing anywhere from 40W to 150W of power. Each of the 15 cores supports multithreading so that each Ivytown chip can run 30 threads at the same time.

Intel came to the odd core count by arranging the cores across three columns. It also has 40 PCI-Express 3.0 lanes.
