In addition to the Ryzen 7 5800X3D, which AMD claims to be the world's fastest gaming processor, AMD gave its desktop processor product-stack a major update, with as many as six other processor models spanning a wide range of price-points that help the company better compete with the bulk of the 12th Gen Core "Alder Lake" processor lineup. The new lineup sees the introduction of the Ryzen 7 5700X (not to be confused with the Ryzen 7 5700G). The 5700X is based on the same "Vermeer" multi-chip module (MCM) as the Ryzen 7 5800X, unlike the 5700G, which is a desktop APU based on the "Cezanne" monolithic silicon. Both "Vermeer" and "Cezanne" are based on the "Zen 3" microarchitecture.

The Ryzen 7 5700X is an 8-core/16-thread processor clocked at 3.40 GHz base and 4.60 GHz boost, compared to the 3.80 GHz base and 4.80 GHz boost frequency of the 5800X. Another key difference is its 65 W TDP, compared to 105 W of the 5800X, which could differentiate its boosting behavior and overclocking headroom compared to the 5800X. AMD is pricing the 5700X at USD $299 (MSRP), making it a competitor to the Intel Core i5-12600KF. Interestingly, the retail PIB (processor-in-box) package of the 5700X does not include a stock cooler despite its 65 W TDP. A 95 W-capable Wraith Spire wouldn't have hurt.
 
Next up, we have the Ryzen 5 5600 6-core/12-thread processor. This chip is the spiritual successor to the popular Ryzen 5 3600, despite AMD according that title to the 5600G APU. The 5600 is based on the same "Vermeer" MCM as the 5600X, and tones down on clock speeds. It runs at 3.50 GHz, with 4.40 GHz boost, compared to the 3.70/4.60 GHz clocks of the 5600X. The TDP is the same as the 5600X, at 65 W, and luckily, a Wraith Stealth cooler comes included. AMD is pricing the Ryzen 5 5600 at $199 (MSRP), pitting it against the likes of the Core i5-12500.

The Ryzen 5 5500 is a very interesting part. This 6-core/12-thread processor is based on the same "Cezanne" monolithic silicon as the Ryzen 5 5600G, but with its iGPU disabled. The "Cezanne" silicon physically features 16 MB of L3 cache that's shared among all CPU cores. The processor ticks at 3.60 GHz base, with 4.20 GHz boost. AMD is pricing the chip at $159, and its main competitor appears to be the Core i5-12400F.

Lastly, AMD launched a trio of Ryzen 4000 desktop processors for the first time in the retail channel. These are based on the 7 nm "Renoir" monolithic silicon, and feature "Zen 2" CPU cores. The lineup begins with the Ryzen 3 4100, a 4-core/8-thread chip at $99, and moves up to the Ryzen 5 4500, a 6-core/12-thread chip at $129. The highlight here is the Ryzen 5 4600G, a fully-fledged APU (including iGPU), with a 6-core/12-thread setup, at $154. Given the much lower IPC of the "Zen 2" cores compared to the "Golden Cove" ones in Core i3 "Alder Lake" series, it's hard to pinpoint what chips these compete with—perhaps leftover 10th Gen Core "Comet Lake" Core i3 and Core i5 inventory.

These processors will be generally available from April 4, 2022, while the 5800X3D comes on April 20.
 
I assume AMD is trying to compete with Intel on price point.
