Intel will fully support PCIe 4.0 but must change the motherboard

Because of the influence of internal and external factors,IntelRecent product line promotion is a bit chaotic, just released is 10-generation Ice Lake Core Rui, but only U/Y series low-power mobile version, is expected to follow the next 14-nm Comet Lake U series mobile version, early next year is 14-nm Comet Lake desktop version, and then Rocket Lake, Tiger Lake.

From the current signs, Intel 10 nm is limited to mobile end in a short period of time, and desktop end continues to improve by 14 nm. Pessimistic expectation is that 10 nm will not be seen on the desktop before 2021, or even the possibility of crossing directly to 7 nm will not be ruled out.

Exposure from across the Strait said,Rocket Lake platform will be born in 2020-2021, which will introduce many significant changes, including PCIe 4.0 bus, 12-generation core graphics card, native HDMI 2.0, and the use of DMI X8 interconnection channels between processors and chipsets.

Now DMI 3.0 is actually PCIe 3.0 x4, and upgrade to PCIe 4.0, DMI 8x, the number of links doubled, transmission bandwidth doubled, the actual bandwidth is four times, to 16GB/s, can easily meet NVMe.SSDHigh bandwidth requirements such as Lightning 3 external graphics card and USB 3.2 device.

Rocket Lake processors can be paired with CMP-H (Coffee Lake) or TGP-H (Tiger Lake), both of which support DMI 8x, but are no longer compatible with CMP-V PCH (Coffee Lake), so future upgrades will be troublesome, and the names of the specific commercial models of these chipsets are still uncertain.

On the mobile side, Intel will eventually introduce PCIe 4.0, but so on.

At present, the main point of exposure is NUC mini-machine. The current Hade Canyon will be upgraded this autumn.Ghost CanyonIt can be equipped with the top 8 core i9-9980HK of mobile terminal, and can choose independent graphics card.

Then it will be upgraded to Phantom Canyon again by 2020-2021 with a 10nm Tiger Lake processor and, of course, a U-Series, which is only the highest-end series of 28W and will also have PCIe 4.0 to support X4 links.More details are not available.

Ghost Canyon can also choose independent graphics cards, such as RTX 2060, GTX 1660 Ti, mainstream level, and lightning 3/USB-C interface, maximum 64GB memory, two M.2280, 2.5G network cards, 802.11ax Wi-Fi 6 wireless network card, USB 3.1 interface, etc. It can also customize vacuum chamber heat dissipation, RGB lamp efficiency.
