An intriguing offshoot of Intel's Meteor Lake generation of processors has been discovered by hardware sleuth momomo_us—an iBase MI1002 motherboard specification sheet contains references to a 14th Gen Core Ultra (Meteor Lake-PS) family, with a next-gen LGA1851 socket listed as the desktop platform. The industrial iBase Mini-ITX workstation board is "coming soon" according to a promotional image—this could signal a revival of Meteor Lake outside of laptop platforms. 2023 was a bit of a rollercoaster year for MTL-S SKUs (on socket LGA1851)—one moment Team Blue confirmed that it was happening, then a couple of days later it was disposed of. The upcoming Arrow Lake processor generation seems to be the logical taker of this mantle, but the (leaked) existence of Meteor Lake-PS throws a proverbial spanner into the works.

iBase's MTL-PS-ready boards will be niche "industrial/embedded" items—according to Tom's Hardware: "Intel hasn't officially revealed Meteor Lake PS, but given the "PS" designation, these upcoming processors target the IoT market, similar to Alder Lake PS. Therefore, it's safe to assume that Intel is bringing the mobile Meteor Lake processors to the LGA1851 socket...Although the motherboard has (this) socket, no chipset is present because Meteor Lake PS is the spitting image of the Meteor Lake chip and doesn't need a PCH." Team Blue is hyping up Arrow Lake (ARL-S) as its next-gen mainstream desktop platform, with a launch window set for later in 2024—by sharp contrast, Meteor Lake PS parts are highly unlikely to receive much fanfare upon release.

A few weeks ago, we spotted an Intel Core Ultra 7 1003H Meteor Lake-P processor in the wild, running a PugetBench set of benchmarks. Today, we are in luck as there is another Meteor Lake-P processor running in the wild, spotted by @InstLatX64 on Twitter. Called Intel Core Ultra 7 1002H, the CPU represents a similar SKU to the previously discovered 1003. Also, having 16 cores in total, they are split into two categories: 6 Performance cores, and ten Efficient cores, two of which are on the SoC die, divided from the remaining eight on the compute die. Interestingly, only P-cores feature 2-way hyperthreaded, so 12 threads from P-cores and ten threads from E-cores combine into 22 threads.

What we don't know is the frequency of this chip and the position it plays in the Meteor Lake-P family of processors. The screenshot states a potential base clock of 3000 MHz; however, it could be an early engineering sample chip, so we have to wait for the final design. With 1003H having exactly the same core/thread number, we expect that the newly discovered 1002H has potentially lower clocks and TDP to match.

The Linux 6.3 Kernel has been patched and a couple of developer notes indicate that support for Intel's upcoming Meteor Lake-S Desktop CPU lineup has been added. The subject matter of this memo is "Add support for Meteor Lake-S SPI serial flash," and the driver list of supported devices has been updated with Meteor Lake-S PCI IDs. Intel is ramping up for the launch of its 14th generation processors, scheduled for a possible second half of 2023 release window, and is ready to roll out some new product naming spiel at the same time.

A "P" type 14th generation range is also discussed in the patch notes: "Intel Meteor Lake-S has the same SPI serial flash controller as Meteor Lake-P. Add Meteor Lake-S PCI ID to the driver list of supported devices." Meteor Lake-P likely refers to mobile variants, with a lot of previously leaked information providing an in-depth look at Intel's "Tile" chip design. Rumors of the desktop variants getting canned have persisted (in 2022 and early 2023) due to a lack of insider info, but last month it emerged that the Meteor Lake-S family was alive and well to some degree - Intel has restricted the product range with offerings of budget "i3" and mid-range "i5" SKUs only. Who knows what sort of branding/naming scheme they have in mind to distinguish between desktop and portable processors.
