It has been just over a year since Santa Clara released its Nehalem-based octal-core Beckton processors. Whereas Beckton was focused entirely on performance and architectural efficiency, these new Xeons are more balanced. The new chips boost the core count to ten (up to 20 threads with HT enabled) and will be offered at a wide range of power envelopes. The new E7 series incorporates the benefits of the Sandy Bridge architecture, its support for new security processing instructions, and its improved power management technology. Intel has also baked in support for low-voltage DIMMs, which allows vendors to opt for 1.35v products. The power savings, at 1W per DIMM, might not sound like much, but the E7 series supports up to 2TB of RAM in a 4S system. According to Intel, low-voltage DDR3 can cut a server's power consumption by up to 128W."
