As part of a new Press Release, MSI revealed PCIe Resizable Bar support for their 400-series of Intel LGA 1200 motherboard, but they also revealed a previously known Rocket Lake-S series processors.

Rocket Lake is Intel's next-generation processor, the successor of today's LGA 1200 Comet Lake offerings, which will offer PC builders increased single-threaded performance, new architectural enhancements and support for PCIe 4.0.

MSI's press release used the screenshot below, highlighting their use of an 8-core Rocket Lake processor on a Z490 motherboard. This processor was screenshotted with a 4.3GHz clock speed and a boost clock speed of 5GHz. These clock speeds are likely to be lower than retail versions of Intel's flagship Rocket Lake CPU models. A TDP of 125W is also shown.

MSI's screenshot also shows that Rocket Lake will support AVX512F instructions, which Intel's current-generation Comet Lake processors cannot utilise. Additionally, Rocket Lake appears to supports SHA instructions.

Once it came to light that MSI accidentally leaked Rocket Lake information, MSI pulled their press release from their website.
