Intel To Release Its First 4GHz Processor – Forbes

If information uncovered by Chinese website EXPreview is to be believed, Intel’s Intel’s soon-to-be-released replacement for its current Intel Core i7-4770K CPU will be the company’s first that ships with a clock speed of 4GHz.

The new CPU is part of a range of refreshed chips due to be launched some time in June, with the two high-end K-series models codenamed Devil’s Canyon called the Core i5-4690K and Core i7-4790K, with the latter offering the magic 4GHz number. Using Intel’s Turbo Boost technology, the CPU will actually increase this figure to 4.4GHz when under load for extra performance.

The cheaper Core i5-4690K will apparently offer a default clock speed of 3.5GHz and will Turbo Boost to 3.9GHz. As I reported here, the new CPUs will also feature an improved thermal interface between the CPU core and heat spreader. Heat has plagued Intel’s Ivy Bridge and Haswell-based processors such as the Core i7-3770K and Core i7-4770K, with many people removing the heatspreaders and using their own thermal paste.

Combined with higher clock speeds, it’s quite possible that the new CPUs could easily reach 5GHz with a good cooler if you overclock them – something that hasn’t been widely possible since its Sandy Bridge-based processors such as the Core i7-2600K.

Intel has also just launched its new Z97 chipset, which provides native support for M.2 and SATA Express Express storage standards that offer up to 10Gbps bandwith compared to 6Gbps currently available using modern SATA ports. However, there is still speculation over support for the new Devil’s Canyon CPUs and indeed for its successor, codenamed Broadwell, expected late 2014/early 2015.

It’s widely expected that the new Z97 chipset will support both new CPUs, however, it’s possible that Intel’s previous chipset, Z87, which is still widely available, may not support all future Devil’s Canyon and Broadwell CPUs.

New Z97 chipset-based motherboards were launched on Sunday and many are currently available online such as Gigabyte's GA-Z97X-UD5H

Intel’s rival AMD, passed the 4GHz mark some time ago and actually has a 5GHz CPU in the form of the FX-9590. However, AMD is known to have a lower clock-for-clock efficiency, meaning its CPUs often don’t quite match Intel’s in terms of performance at the same clock speed.
