We’ve been calling Intel’s next-generation CPU family code-named Nehalem a Penryn-killer because, sadly, AMD’s best and brightest have hardly been that. For those who haven’t sifted the sands of the Internet, and picked the brains of OEM’s and hardware vendors for every detail of Intel’s next-gen microarchitecture, here’s your quick primer on Nehalem that’ll make you big man on campus at the next geekfest.
How Many Cores?
Most Nehalem’s will be native quad-core with all four compute cores on the same physical die. Intel says that the design of Nehalem will also let the company build an eight-core version, codenamed Beckton, for servers. Intel also hasn’t ruled out the possibility of a multi-chip version so could perhaps see a double-die Beckton with 16 cores as well.
HyperThreading Returns
An improved version of HyperThreading will find its way into the core of Nehalem. This improved simultaneous multi-threading, or SMT, will let the OS see a quad-core chip as eight cores. Although some still debate its merit, the implementation of HT in the Pentium 4 generally added 15 percent more performance in multi-threaded applications.
