Intel 28-core 5GHz Desktop New CPU Secret: 14nm Skylake, 265W

Intel’s visit to Taipei’s computer show was impressive, with two 5GHz consumer CPUs, the i7-8086K for the 40th Anniversary Edition and the mysterious high-end flagship for the 28 cores. Among them, 28 cores were processed. In the Cinebench, the device actually touched the 7334cb multi-threaded performance, to know last year's 18-core i9-7980XE but 3364cb. Many very obstinate hardware media confirmed further information, interested in it may wish to understand in depth.

Previously it was said that the 28-core is based on the Cascade-X new server architecture, but not so, this is a consumer platform, but AnandTech said that Intel confirmed to it that consumer products based on Cascade-X will also have at the end of the year.

At present, the mainstream media tends to base this on Skylake-XCC (extreme core count), and the key point is that with 14nm process, Die area is 700 mm2, and 30 Mesh interconnection buses are used internally.

The 28-core CPU interface was upgraded to LGA3647. Asus (ROG, Dominus) and Gigabyte also previewed the relevant motherboards at the computer show. The E-ATX board design, 6-channel DDR4 memory, and the CPU has 48 PCIe 3.0 channels. Supports 2 full bandwidth PCIe 3.0 x16 devices.

Because of the basic frequency of 2.7GHz, Intel revealed that 5GHz is the result of water-cooled overclocking. The demonstration uses the 1770W water-cooled compressor 'suppression'.

Of course, it should be noted that the LGA3647 interface theory supports up to 265W, so the highest TDP of the 28 cores is this number. Since the i9-7980XE overclocks to 4.9GHz requires more than 1000W of power, the 28 core will only be higher.
