Comet Lake-S Us Are Obsolete; LGA 1700 Socket is Coming
The Intel Comet Lake-S and Rocket Lake-S U will become completely obsolete after only a dozen or so months on the market. In 2021 the company intends to introduce a new, incompatible with its predecessors, socket LGA 1700, which will appear together with the 12th generation Alder Lake-S chips.

extremely expensive Z490 chipset and LGA 1200 socket, will become obsolete after just one and a half year on the market. According to repeated rumors from Intel's partners, in 2021, the 12th generation of Alder Lake-S processors, using a brand new and incompatible LGA 1700 socket, will come to the stores.
This means that Intel intends to Z490 motherboards for only about 18 months. During this time, new Comet Lake-S and Rocket Lake-S processors will dominate the market. The good news is that with the launch of Adler Lake, the company wants to slow down the pace of technological change a bit. According to the leaks, Intel will take the example of AMD in this respect. The LGA 1700 socket will at least three generations of Us.
LGA 1700 socket will be larger than LGA 1200 and LGA 1151 and will measure 45 mm by 37.5 mm on the motherboard. This change will most likely entail a lack of for existing cooling systems. Gamers with expensive fans, for example, will have to replace these components as well, which will cost them extra.

New motherboards based on Z490 chipset and LGA 1200 socket, such as the ASRock Z490 Phantom Gaming 4SR visible here, may become obsolete after only one and a half year after launch.
The new dimensions of the socket will directly affect the physical size of the processor, giving the manufacturer additional scope for changes to its architecture. Industry specialists expect its to use technology used in mobile chips, modeled on ARM's big.LITTLE U. It is based on two different types of computing units in the processor. Half of the available chip cores work to ensure maximum performance, while the other half focuses on working with the lowest possible power consumption, which may prove useful given the reported huge demand for power from the Comet Lake-S U family.
It is also worth mentioning that processors and motherboards using LGA 1700 are expected to offer for PCIe 5.0 sometime after the release. However, Intel does not plan to DDR5 memories, which are still at the prototype stage, and it is estimated that they will reach a wider group of consumers in two years.
