Overview
A CPU enthusiast posted binning results for 13 samples of the new Ryzen 7 9850X3D on the overclock.net forums. The data confirms that the 9850X3D is effectively an over‑clocked 9800X3D, requiring higher core voltages to reach a boost clock that is 400 MHz above the 9800X3D.
Binning Data Summary
Key findings from the 13 chips include:
- Default boost clocks range from the advertised value up to +400 MHz.
- Core voltage (Vcore) varies significantly; the best‑performing chips still need more voltage than a typical 9800X3D.
Memory & Infinity Fabric Performance
All 9850X3D samples could hit 2200 MHz on the Infinity Fabric, with three top samples reaching 2233 MHz. Memory speeds were stable between 8200 MT/s (worst) and 8600 MT/s (best). Notably, the chips with the highest fabric and memory clocks did not have the lowest core voltages or highest boost clocks.
Voltage Comparison with 9800X3D
HardwareLuxx’s 9800X3D reference required 1.119 V to achieve its maximum advertised boost. Compared to the 9850X3D samples:
- Best 9850X3D uses ~13 % less voltage than the 9800X3D.
- Worst 9850X3D uses ~21 % less voltage than the 9800X3D.
- Overall, the 9850X3D family consumes more voltage on average to reach higher boost clocks.
Power Consumption & Performance Impact
In‑house testing showed the 9850X3D draws about 30 % more power than the 9800X3D while delivering only a ~3 % average performance uplift. This indicates diminishing returns for the higher voltage and boost strategy.
Conclusion
The binning data confirms that the Ryzen 7 9850X3D is not merely a better‑binned 9800X3D; it is essentially a factory over‑clocked version that relies on higher voltages to achieve modest clock gains. For most users, the extra power draw may outweigh the small performance benefit, making the 9800X3D the more efficient choice for typical workloads.
