Intel today announced forth generation Core i7 Extreme processors, including flagship six-core i7-4960X model. Two other forthcoming Extreme products are Core i7-4930K and i7-4820K, featuring six and 4 CPU cores. All Extreme CPUs are built on Ivy Bridge-E core, which, with the exception of reliability features, has very similar feature-set to unreleased Xeon E5-1600 v2 server microprocessors. Like their server counterparts, the Core i7 Extremes use socket LGA2011, officially support 3.0 specification of PCI Express interface, and have quad-channel memory controller, that works with DDR3-1866 memory. Besides more efficient microarchitecture, stock speeds of Ivy Bridge-E SKUs were increased by 100 MHz or 200 MHz depending on SKU. The chips also have new extensions to x86 instruction set.
As was already mentioned, two six-core models are Core i7-4960X and i7-4930K. These processors operate at 3.6 GHz and 3.4 GHz, and have Turbo Boost frequencies of 4 GHz and 3.9 GHz respectively. The quad-core i7-4820K runs at 3.6 GHz, and up to 3.9 GHz. The CPUs support Hyper-Threading technology, which allows i7-49xx parts to process up to 12 threads at once (8 threads for the i7-4820K). All Core i7s come with unlocked clock multiplier, VTx and VT-d technologies, and support for AVX instructions. The CPUs have 130 Watt TDP, and they are compatible with older motherboards, based on X79 chipset. The microprocessors will be priced from $310 to $990, which is close enough to $294 - $999 price range of currently available i7-38x20/i7-39xx Extreme CPUs. According to Intel, the Core i7-4960X and two other SKUs will be launched next week during Intel Development Forum show in San Francisco.
