AMD Rembrandt Mobile
AMD announced Rembrandt 6000-series mobile processors with Zen 3+ CPU cores and RDNA2 integrated graphics.
The 8-core processors (e.g. 45W Ryzen 7 6800H and 15W Ryzen 7 6800U) all have 12 RDNA2 graphics cores (CUs), up from the previous generation Cezanne's 8 Vega graphics cores. This could mean a doubling of graphics performance. On the other hand, the 6-core processors (e.g. 15W Ryzen 7 6600U) slash this in half to only 6 RDNA2 CUs.
Rembrandt uses DDR5 or LPDDR5 memory and adds support for 40 Gbps USB4 ports, PCIe Gen 4.0 GPUs and storage, HDMI 2.1 and DisplayPort 2, and AV1 hardware decode.
There are also three "Barcelo" models which are refreshes of Cezanne chips (8-core Ryzen 7 5825U, 6-core Ryzen 5 5625U, and 4-core Ryzen 3 5425U).
Rembrandt will be one of the first products to integrate Microsoft's "Pluton" security chip.
Intel Alder Lake Mobile
Intel announced Alder Lake-H (high performance) and Alder Lake-U (low power) mobile processors, with a heterogeneous microarchitecture featuring performance (P) and efficiency (E) cores.
Alder Lake-H has a "base power" of 45 Watts and a "max turbo power" of 115 Watts. The top i9/i7 chips have 14 cores (6P + 8E). In the middle there is an i7-12650H with 10 cores (6P + 4E) and an i5-12600H and i5-12500H with 12 cores (4P + 8E), so that may lead to some confusion. Finally, there is an i5-12450H with 8 cores (4P + 4E).
Alder Lake-U has a "base power" of 15 Watts and a "max turbo power" of 55 Watts. At the top there are a few chips with 10 cores (2P + 8E) and 80 or 96 graphics execution units (EUs). The i3-1215U has 6 cores (2P + 4E) and 64 EUs. Finally there are a Pentium 8505 and Celeron 7305 with 5 cores (1P + 4E) and 48 EUs.

The 15W Ryzen 7 6800U looks pretty attractive. If that 15W is real, that should be able to be dissipated in even something as thin as an XPS (my i7 XPS-13 thermally throttles before it even finishes booting up). But, will have to see if the new MS designed "security" processor built-into the new AMD processors (and to be added to Intel and Qualcomm processors too), is some scary back-door / DRM bullshit, in which case, so long AMD and Intel.

The aggressive cut down to 6 CUs "kills" the 6600U (makes it equivalent to around Cezanne/Vega 8 CUs, I guess). Should make the 8-cores more popular.
Rembrandt holds the line at 1080p. Going forward, AMD's Phoenix and Strix Point will only improve on that, and further reduce the need for discrete graphics.
Keep in mind that those U chips are going up to more like 28W in some cases, which they should given sufficient cooling. However some of AMD's slides compared 15W 5800U to 28W 6800U:

Everyone is going to have to decide whether Pluton fears are FUD, because it or something like it will come to everything of consequence. Inb4 SiFive is next.

Pluton is bad news. Might be the end of the PC industry as we know it. I don't think it will be in Zen 4, but it will probably be in whatever comes next.
For those not up on the news, Pluton basically means that Microsoft will have veto power over all software. It's not just secure boot turned up to 11, it's turned up to a billion.
