Intel's latest Extreme Edition package boasts eight cores, a massive 20MB smart cache, support for the latest DDR4 memory, and is accompanied by the all new X99 chipset.
Intel used their presence at PAX Prime in Seattle, WA to reveal their new Haswell Extreme Edition CPU as well as two new unlocked Haswell CPUs. These chips are fast.
Intel is apparently accelerating the launch date for their next gen Haswell-E CPUs and X99 chipset, with manufacturers also rumored to be ready to roll out a number of new motherboards to choose from.
Sneaking in before the launch of Haswell-E - which is expected next year, are three Core i7 Ivy Bridge-E processors with either six or four cores and up to 15MB of Smart Cache.
Some leaked slides seem to point toward an 8-core desktop CPU from Intel coming late next year. The chip is supposedly based on the Haswell architecture and brings DDR4 support and great performance.
