Intel unveils Devil's Canyon, its first 4GHz CPU, plus a 20th-anniversary Pentium processor

Michael Brown | June 4, 2014
Intel's fifth-generation Core processor family--code-named Broadwell--might be late, but the company has cooked up a couple of brand-new Haswell-class desktop CPUs that PC enthusiasts are sure to dig. Code-named Devil's Canyon, Intel unveiled the all-new Core i7-4790K and Core i5-4690K processors at Computex on Tuesday (Taiwan time). Intel is also marking the 20th anniversary of its Pentium processor by introducing the all-new Pentium G3258.

Consumers will be able to buy the new CPUs with or without Intel's own heatsink and fan, but I predict most DIYers will favor third-party cooling solutions from the likes of Corsair, Zalman, NZXT, and others.

While both Devil's Canyon parts are quad-core CPUs, the Core i7 variant supports eight execution threads, where the Core i7 model supports only four. By the same token, the Core i7-4790K will have 8MB of cache, where the Core i5-4690K has 6MB. But both processors will have the same integrated graphics processor — an Intel HD 4600 — and both will be capable of addressing DDR3/1600 memory over two channels. Intel expects the new Core i7 part to sell for $339 and the Core i5 for $242 (that's for quantities of 1000 without a heatsink and fan).

The Pentium reinvented

Graff also unveiled an unlocked Pentium processor, the Pentium G3258. It will operate at a base frequency of 3.2GHz, but like the Devil's Canyon parts, it will have an unlocked multiplier to attract PC enthusiasts. This dual-core part will have integrated Intel HD Graphics and be capable of addressing DDR3/1333 memory over two channels. It will be compatible with Socket 1150 motherboards with Intel 8- or 9-series chipsets, and it will have a TDP of 53 watts. Intel expects it to cost $72 (in quantities of 1000, without a heatsink or fan).

This isn't the first time Intel has revealed information about Devil's Canyon and the new Pentium processor. Graff discussed both parts at a press briefing related to the 2014 Game Developers' Conference in March.
