Bringing its 45nm Hi-k Nehalem microarchitecture to mainstream desktops and entry-level servers, Intel's new set of processors comprises: two Core i7 chips, a Core i5, and six Xeon 3400 series.For 'high-performance desktops', read suitability for gaming, media processing and the more demanding apps.
All the processors are lead- and halogen-free, states Intel, and feature its Turbo Boost Technology (which enables a core to run faster than the base operating frequency if it's operating below power, current, and temperature specification limits). The top-of-the-line Core i7 processors also support Intel's Hyper-Threading Technology (thread-level parallelism on each processor).
The chipset to note is the Intel P55 Express Chipset.
"The new Core i7 and i5 processors are the first Intel processors to integrate both a 16-lane PCI Express 2 graphics port and two-channel memory controller, enabling all input/output and manageability functions to be handled by the single-chip Intel P55 Express Chipset. Previous Intel chipsets required two separate chips. A new Direct Media Interface (DMI) connects between the processor and chipset," states Intel.For reactions to the Lynnfield chips read here and here and here.
