One of the most anticipated CPU products this year is Core i7-4960X, that will take place of the Core i7-3970X as the fastest consumer processor. The first details on this model surfaced in March 2013, when VR-Zone news site published specifications of three upcoming Ivy Bridge-E models. Shortly after that, in April, a user in coolaler forum posted preliminary benchmarks of the chip, that showed about 5% - 8% better performance in synthetic tests over the 3970X. A sample of the i7-4960X CPU was also tested by Tom's Hardware site in July, and they noted its significantly lower power consumption in comparison with previous generation of i7-39xx microprocessors. As of beginning of August, Intel 4960X was available for pre-order in one US online shop for the same price as the Core i7-3970X. The CPU is expected to launch from September 4 to September 11.

Intel launches 4th Generation Extreme CPUs
Sep 10, 2013: As expected, Intel launched today three new members of Core i7 family for socket 2011 platform. Packing from 4 to 6 CPU cores, Core i7-4820K, i7-4930K and i7-4960X processors feature newer 22nm manufacturing process, more efficient Ivy Bridge-E core, higher clock speeds and memory bandwidth, and official support for PCI Express 3.0 interface. With the exception of somewhat more expensive i7-4820K, the 4th generation products are offered in the same price range as i7-3xxx Sandy Bridge-E models.

Intel announces next generation extreme CPUs
Sep 03, 2013: 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.
