Intel's Arrow Lake-S and Meteor Lake-S processors will require new motherboards with LGA 1851

Intel will release Raptor Lake-S processors in the second half of the year, which, while bringing evolutionary improvements over Alder Lake-S, will remain compatible with the LGA 1700 socket.
Informed sources report that their successors will be offered in the new LGA 1851 design, which implies the use of new motherboards.
Picture source: BenchLife.infoSpeaking statements are the Chinese site BenchLife.info, which has repeatedly confirmed the correctness of their predictions.
The information distributed recently by a popular You-Tube channel about Intel's intentions to move processors to run with 2551 pins turned out to be only partly true.
The fact is that the Arrow Lake and Meteor Lake desktop processors will be available in LGA 1851 version, while the Intel plans to move to Intel's version with 2551 pins, which will surely be combined with BGA mounting type and used in mobile segment.
According to a Chinese source, the LGA 1851 CPU will retain the length and width of its predecessor in the LGA 1700 design (37.5 x 45 mm), but its mounting height relative to the motherboard will range from 6.83 mm to 7.49 mm, which is 0.09-0.1 mm more than the LGA 1700 design.
Theoretically, this will maintain compatibility with cooling systems that ran on LGA 1700 processors, but things are not so clear with the clamping force due to the change in mounting height of LGA 1851 processors.
In all likelihood, the processors of this generation will be a bit higher because of more complex layout, which implies placing two crystals on one substrate.Asymmetric shape of crystals, in turn, will not contribute to the even heat removal by the cooling system soleplate, so manufacturers of the latter will probably offer new revisions of their products, optimized to work with processors in the LGA 1851.
Characteristically, the Chinese primary source insists that Arrow Lake-S processors will come out first, and only then Meteor Lake-S will appear, although most other sources consider the reverse sequence.

Intel will talk about Meteor Lake and Arrow Lake processors at the end of August

The organizers of the Hot Chip Symposium 2022 conference have shared the program of the event, which will take place at the end of August this year.
Due to the ongoing COVID-19 pandemic, the conference will be held online from August 21 to 23.
Confirmed guests of the event will be Intel, AMD, Arm, Nvidia.
Samsung, Tesla, MediaTek and Cerebras are also expected to attend.Mobile Meteor Lake.
Image source: IntelOne of the topics, which Intel plans to cover during his speech, will be a 3D packaging of chips Faveros for consumer processors.
Its implementation is planned in the Meteor Lake (14th generation Core) and Arrow Lake (15th generation Core) series of chips.
The Meteor Lake processors will include the chip with integral computational units, based on Intel process 4 (7nm), embedded GPU chip with 3nm TSMC process (N3), as well as the chip with interfaces (SoC-LP), based on TSMC N4 or N5 processes (different versions of 5nm technology).
The Arrow Lake series, in turn, will use Intel's 20A process technology for the first time, as well as TSMC's N3 (3nm) process technology.
Intel will also talk about new server gas pedals Ponte Vecchio and Intel Xeon D 2700 and Xeon D 1700 processors at Hot Chips.There will be other companies at the conference at the end of August.
AMD is going to talk about the mobile Ryzen 6000.
This series of chips was introduced at CES 2022 earlier this year and is just starting to appear in notebook lineups.
The series consists of Ryzen 6000H processors with TDP from 35 to 45W, as well as Ryzen 6000U models with TDP of 15-28W.
It is possible that AMD is going to show new chip models with TDP less than 15W at Hot Chip Symposium 2022.NVIDIA will pay attention to supercomputing.
In particular, the vendor will be talking about Hopper architecture for server gas pedals and will probably also be talking about its 144-core Grace processor.Tesla has planned two presentations.
During them, the company is going to talk about its supercomputer Tesla Dojo.
In particular, the manufacturer will pay attention to the microarchitecture, which is used in its basis.
In addition, the automaker will talk about how Dojo can accelerate machine learning.MediaTek will talk about the features of its flagship Dimensity 9000 processor series for smartphones, and Arm will discuss the details of its server hardware platform Morello with enhanced security features.
