What this page is—and isn’t
This is not a TWW hands-on review. TWW has not physically tested or independently benchmarked this product. This page organizes the manufacturer’s specifications, practical buying considerations and links to published external testing where available.
Any performance or usability conclusions attributed to an outside publication remain that publication’s findings. They are not presented as TWW measurements.

What independent testing reports
Tom’s Hardware’s January 2026 lab review described the 9850X3D’s gains over the 9800X3D as marginal relative to its additional power consumption. Review conclusions depend on the tested games, power settings and comparison set; TWW has not repeated these benchmarks.
Potential strengths
- Large L3 cache and the X3D design target latency-sensitive gaming workloads.
- AM5 provides a known desktop platform with DDR5 support.
- Tom’s Hardware published direct gaming and power comparisons with the 9800X3D.
Limitations and buying cautions
- Tom’s Hardware measured only a small average performance increase over the 9800X3D while reporting a substantially larger power increase in its test suite.
- It remains a premium gaming-focused CPU; productivity value depends on the application and competing prices.
- A compatible cooler and motherboard are additional costs; check BIOS support before an upgrade.
Who should consider it?
- High-refresh-rate gaming builds
- Existing AM5 builders checking CPU and BIOS compatibility
- Buyers comparing the 9850X3D with discounted alternatives
