Best prices on AMD Ryzen 9 9900X3D processors
Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.
Top pick: AMD Ryzen 9 9900X3D — the exact chip you asked for, and the cheapest listing I found is at Walmart. It's a 12-core/24-thread AM5 part with 3D V-Cache, up to 5.5 GHz boost, 120W TDP and DDR5 support, so it drops into an existing AM5 board with a BIOS update. Check the seller is Walmart itself rather than a marketplace reseller before you buy.
Who the others suit:
- Ryzen 7 9800X3D — the better buy if gaming is the priority; fewer cores, but the same cache trick and easier to cool.
- Ryzen 7 9700X — a sensible step down if you mostly game and do light creative work.
- Ryzen 5 9600X — the budget route for a first AM5 build.
- Intel Core Ultra 7 270K Plus / Ultra 5 250K Plus — only if you're building on an Intel board instead.
One caution: the 9900X3D listings carry a low rating from very few reviews, so buy from a store with a clear return policy.
