    Introducing "Core i7", Intel's Next Generation CPU

    I just stumbled across the latest news on Intel's next-gen CPU dubbed Core i7. Intel will make an announcement about this processor on August 11 with release in the 4th Quarter of this year. Price range is from $284 all the way over $1000.

    And I just upgraded my computer too with a Quad Core Q9450!

    • Two, four, or eight cores
    • 731 million transistors for the quad core variant
    • 45 nm manufacturing process
    • Integrated memory controller supporting DDR3 SDRAM and between one and six memory channels[citation needed]
    • Integrated graphics processor (IGP) located off-die, but in the same CPU package
    • A new point-to-point processor interconnect, the Intel QuickPath Interconnect, replacing the legacy front side bus
    • Simultaneous multithreading, which enables two threads per core. Simultaneous multithreading has not been present on a consumer Intel processor since 2006 with the Pentium 4 and Pentium EE. Unlike the SMT implementations on the Pentium 4 and the Atom, SMT on Nehalem is referred to as 'MTT'.
    • Native (monolithic, i.e. all processor cores on a single die) quad- and octo-core (8) processors
    • The following caches:
    • 32 KB L1 instruction and 32 KB L1 data cache per core
    • 256 KB L2 cache per core
    • 2-3 MB L3 cache per core shared by all cores
    • 33% more in-flight micro-ops than Conroe
    • Second-level branch predictor and second-level Translation Lookaside Buffer
    • Modular blocks of components such as cores that can be added and subtracted for varying market segments
    • 1.1x to 1.25x the single-threaded performance or 1.2x to 2x the multithreaded performance at the same power level
    • 30% lower power usage for the same performance
    • According to a preview from AnandTech "expect a 20-50% overall advantage over Penryn with only a 10% increase in power usage. It looks like Intel is on track to delivering just that in Q4."
