AMD has announced its new Ryzen 4000-series mobile APUs for laptops, including 8-core parts for both 15W and 45W TDPs. The new chips all support up to 64 GB of LPDDR4X memory.
At the 15W TDP, Ryzen 7 4800U has 8 "7nm" Zen 2 cores (16 threads), and 8 "7nm" Vega graphics compute units (CUs) which perform better than the 11 Vega CUs from the previous generation, due in part to a much higher 1750 MHz clock speed. There is also an 8c/8t/7CU Ryzen 7 4700U, 6c/12t/6CU Ryzen 5 4600U, 6c/6t/6CU Ryzen 5 4500U, and 4c/4t/5CU Ryzen 3 4300U.
At the 45W TDP, Ryzen 7 4800H has 8c/16t at a 2.9 GHz base frequency (compared to 1.8 GHz for the 4800U), but only 7 graphics CUs. Ryzen 5 4600H has 6c/12t with 6 CUs, and the Ryzen 7 4800HS is identical to 4800H except for a lower TDP, and will be an ASUS exclusive chip for the first six months.
At the low end, there are two new Zen-based 15W laptop chips, a 2 core, 4 thread Athlon Gold 3150U, and a 2 core, 2 thread Athlon Silver 3050U.
AMD's 64-core Threadripper 3990X will be available on February 7th for $3,990, double the price of the 32-core TR 3970X. A 48-core version was not mentioned.
AMD has launched Radeon RX 5700M and RX 5600M discrete GPUs for laptops to complement the RX 5500M that was previously launched. A mid-range Radeon RX 5600 XT desktop GPU was also announced.

The low-power "U" parts have 4-8 physical cores?! It's a great time to be alive!

It's amazing isn't it? The laptop I'm using has 8GB of RAM, which is completely unremarkable of course, but try telling the me from 1999 that I would have access to that much RAM.
I may have been using an 8GB HDD at the time.

It's too bad that the great stagnation of 2012-present happened. Otherwise we might be talking about $1/GB RAM. Prices are set to rise again [linuxreviews.org], continuing the historic stagnation trend. Little incidents [anandtech.com] like this don't help.
There is clearly room to add more, as 3D packaging and other techniques can already get server module size up to 256 GB [anandtech.com] or LPDDR4X/5 package size to 12-16 GB. 2D density will also increase beyond the 16 Gb die size.
No amount of RAM is necessarily too much. It can all be used for caching or the basis of a "universal memory" system.

$1 per GB would be great.
Haven't there been several prosecutions for price fixing?

It will probably never stop. The punishments are a slap on the wrist compared to the DRAM market revenues.
China is trying to become a major producer of DRAM and NAND which should help things, reversing the consolidation that happened when Elpida died.

The Ryzen 7 4800U looks like it will be a monster.
I would still skip it since it won't have AV1 hardware decode, Navi/RDNA graphics could be added next year, and it's being indicated that Zen 3 will not be just a slight performance bump like Zen+ was. Even without a core count increase, there could be another 15-20% performance increase from IPC and clocks.
But even if you don't want to get it, this lineup could lead to more design wins and AMD being taken seriously in more laptops. It depends on how power efficient it is compared to Intel.
There may be another 45W coming, a Ryzen 9 4900H. It was in the rumor mill but not the announcement.
