Intel releases 15-core Xeon E7 v2 processor

At ISSCC last week, Intel shed more light on its 15-core Xeon E7 v2 processor. Today, the Xeon E7 v2 lineup made its official debut. Intel says we can already look forward to more than 40 systems from 21 different vendors.

The Xeon E7 v2 family supplants the Xeon E7 series, which was based on 32-nm Westmere-EX silicon and featured up to 10 cores. Xeon E7 v2 chips have up to 15 cores and can populate 32-socket servers. According to Intel, they deliver up to twice the performance, three times the memory capacity, and four times the I/O bandwidth, not to mention support for Intel's Data Protection Technology.

The full lineup of Xeon E7 v2 chips can be perused here in the official product brief. 15-core variants with the largest thermal envelope (155W) run at 2.8GHz with 37.5MB of cache and 8 GT/s QuickPath connectivity. The lowest-power models in the list have 105W TDPs and run at 2.3GHz with 24MB of cache and 7.2 GT/s of QuickPath bandwidth. There was also talk of 40W, 1.4GHz models at ISSCC last week, but I don't see those in the list. Perhaps they're coming later, or maybe I'm just not looking in the right place.

In any case, Intel says the Xeon E7 v2 series is fit for a "variety of industries from retail and healthcare to banking and transportation." The lineup's improvements over the previous generation can "help businesses that run mission critical applications including business support systems (BSS), customer relationship management (CRM), and ERP to operate more efficiently, at lower cost and with faster response times," the company claims.
