Intel Meteor Lake-S CPUs to support 20x PCIe 5.0 lanes and Wi-Fi 7

There are fresh Meteor Lake-S rumours doing the rounds this week. According to sources, Intel's desktop Meteor Lake CPUs will support as many as 20x PCIe 5.0 lanes, as well as an upgrade to WiFi support. 

According to TLC (via EXPReview), Intel Meteor Lake-S desktop processors will support 4x PCIe Gen4 and 20x PCIe Gen5 lanes. Of those 20 PCIe 5 lanes, 16 are dedicated to the GPU, and 4 are for storage. Compared to Raptor Lake-S, that's a 4x PCIe Gen5 lane increase. Moreover, the Z890 platform it's rumoured to feature four more PCIe Gen4 lanes than Z790, for a total of 24x PCIe Gen4 lanes.

It says support windows 12 on OS list(?)

Now only 6P+8E and 6P+16E, 8P under dev?
That’s everything I know

Other details mentioned by the leaker include not supporting the AVX512 instruction set and introducing Wi-Fi 7-compatible wireless modules. Additionally, the leaker claims that the list of supported OSes included Windows 12. We haven't heard anything about Microsoft launching a new OS, so we don't know if this was a typo or something Microsoft is working on.

Lastly, the report states that Meteor Lake-S processors with 6 P-cores and 8/16 E-cores are ready, but 8 P-core chips could also be in development. According to the latest rumours regarding the release date of Meteor Lake-S, the new chips should launch in 2024, but meanwhile, we should get a refreshed Raptor Lake lineup in 2023.

KitGuru says: Meteor Lake-S is still more than a year away, so take early leaks like this with a grain of salt.
