Nehalem EX will also double the memory capacity with up to 16 memory slots per processor socket, and offer four high-bandwidth QuickPath Interconnect links, which will allow for four-socket or eight-socket systems with as many as 32 or 64 cores and twice as many threads. Other specs include 24MB of shared L3 cache and support for Turbo Boost to shut down some cores and overclock others on programs that need few code threads.
In comparison with the current four-core and six-core “Dunnington” Xeon 7400 processors, Intel says the new Nehalem EX will deliver up to nine times the memory bandwidth, 2.5 times the database performance, 1.7 times the integer throughput, and 2.2 times the floating-point throughput.
