The most popular option will be the Ryzen 7 5700X3D, an 8-core/16-thread Zen 3 CPU with a total of 100MB of cache (64MB of 3D vertical cache, 96MB of L3 cache, and 512KB of L2 cache per core). It works at slightly lower 3.0 base and 4.1GHz max boost clocks, compared to the Rynze 7 5800X3D, but also comes with a rather attractive $249 price tag.
AMD also introduced the new Ryzen 7 5700 CPU, which is bundled with AMD's Wraith Spire cooler. It is also an 8-core/16-thread SKU, works at 3.7GHz base and 4.6GHz max Boost clocks, has 20MB of cache, and a 65W TDP. It will launch at $175.
AMD unveils two new socket AM4 APUs as well, the Ryzen 5 5600GT and the Ryzen 5 5500GT. The Ryzen 5 5600GT is a 6-core/12-thread SKU, while the Ryzen 5 5500GT is a 4-core/8-thread SKU. Both come with integrated Radeon Graphics, or precisely, the Radeon Vega GPU with 7 CUs and 448 Stream Processors. These are priced at $140 and $125, respectively.
Update: AMD has released an update, which states that the Ryzen 5 5500 GT is actually a 6-core/12-thread SKU.
The entire lineup will be available on January 31st.
