A new PassMark entry has surfaced for AMD’s unreleased Ryzen 7 9850X3D, giving the first look at how the chip compares against the current 9800X3D, one of the best CPUs. The listing, which appeared in the database this week and was posted on X, reports a CPU Mark score of 41,840 from a single sample. That places it roughly 5% ahead of the 9800X3D’s 39,962-point average in the same benchmark. PassMark’s breakdown shows a single-thread score of 4,632, compared to the 9800X3D’s 4,425, again landing in the 5% range.
PassMark assigns a high margin of error to early submissions with only one system contributing data, but the figures track with the specifications already associated with the 9850X3D. Shipping details and an inadvertent AMD product-page appearance have pointed to an 8-core, 16-thread Zen 5 part with 96 MB of L3 cache, a 120 W TDP, and a 5.6 GHz boost clock. That is a straightforward frequency increase over the 9800X3D’s 5.2 GHz peak, and the uplift in PassMark’s single-thread test aligns with a step of that size.
The only subtest mentioned by the leakers was PassMark’s Memory Mark, where the new chip reportedly scored 4,421 points. A comparable 9800X3D baseline sits at 4,390. The 1% difference suggests no major change in memory behaviour, which is consistent with the absence of known platform or cache layout changes between the two parts.

The jump from the 7800X3D to the 9800X3D brought a much larger swing in PassMark, with multi-thread throughput rising by about 17% and single-thread performance by 18%. AMD’s architectural changes in Zen 5, paired with higher operating clocks, underpinned that increase. If the incoming 9850X3D holds to the first numbers, it would mark a more minor refinement rather than a repeat of that generational shift.
The comparison also helps demonstrate how AMD’s X3D lineup is stacking up ahead of the company’s next desktop update cycle, which is expected to begin early next year. The 9800X3D has occupied the top position in gaming performance charts since its launch. The 9850X3D’s early showing suggests it should remain in that role, though with a narrower advantage than the one its predecessor enjoyed over the 7800X3D.
Synthetic figures from a single PassMark submission are only a preliminary indication of performance. Broader testing will be needed once retail chips are available, but the PassMark listing offers the first measurable reference point for where the 9850X3D may sit in AMD’s established X3D stack.
