Ryzen 7800X3D or 9800X3D?
Editorial specification comparison · checked 23 October 2026
Both have eight cores, sixteen threads and 96 MB of L3 cache, but use different architectures. The X3D label and maximum boost alone do not establish gaming performance.
For an existing AM5 motherboard, check the CPU-support list and required BIOS before replacing the old processor. Neither researched WOF box includes a cooler.
Check independent measurements in your games at your resolution with a comparable GPU. Specufo has not benchmarked these CPUs. Compare a price difference only when both have current confirmed delivered totals.

The differences at a glance
Manufacturer facts for these exact variants. The order does not declare a performance winner.
CPU clocks are not a gaming score
Compare the socket, memory platform and cooling first. Core count and maximum boost describe the processor; they do not predict frame rates. TDP is a thermal design figure, not measured wall consumption. Check the motherboard CPU-support list and required BIOS.
