AMD Rembrandt Mobile

AMD announced Rembrandt 6000-series mobile processors [videocardz.com] 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. The 6-core processors slash this in half to only 6 RDNA2 CUs.

Rembrandt uses DDR5 or LPDDR5 memory and adds support for 40 Gbps USB4 ports [wikipedia.org], PCIe Gen 4.0 GPUs and storage, HDMI 2.1 [wikipedia.org] and DisplayPort 2 [wikipedia.org], and AV1 hardware decode [wikipedia.org].

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).

Intel Alder Lake Mobile

Intel announced Alder Lake-H (high performance) and Alder Lake-U (low power) mobile processors [videocardz.com], 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 (8P + 6E). 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 is a Pentium 8505 and Celeron 7305 with 5 cores (1P + 4E) and 48 EUs. These chips may be able to throttle down to a TDP suitable for fanless tablets.
