R1
The short version
The Ryzen 7 9800X3D is an eight-core, 16-thread AM5 processor that stacks 3D V-Cache under the compute die instead of on top, which lets it hold higher clocks than earlier X3D chips and makes it fully overclockable. Reviewers consistently rank it at or near the top for gaming. It is far less compelling for heavily threaded work, where cheaper chips with more cores pull ahead, and it ships without a cooler.
Pros
- 96 MB of L3 cache with the cache die placed under the cores, allowing higher boost clocks than earlier X3D parts
- Top-tier gaming performance, with Tom's Hardware measuring a large lead over Intel's best chips at its launch review
- Unlocked for overclocking, a first for the X3D line at launch
- 120 W TDP is manageable without extreme cooling, and the chip drops into existing AM5 boards
Cons
- No cooler in the box; AMD recommends a liquid cooler for best performance
- Eight cores limit heavily threaded work, where similarly priced chips with more cores are faster
- Newer Ryzen 7 9850X3D is a little faster in games at a higher list price
Best for
- High-refresh gaming on a high-end GPU
- Upgrading an existing AM5 board
- Gamers who stream or create occasionally but do not render all day
