AMD Ryzen 9 9900X3D vs AMD Ryzen 7 9800X3D

The Ryzen 7 9800X3D is the better pick for gaming. Its 8 cores run at higher clocks (4.7 GHz base, 5.2 GHz boost) and it is the chip reviewers and owners consistently name as the fastest gaming CPU. The Ryzen 9 9900X3D adds 4 more cores and 8 more threads, which helps in video editing, 3D rendering and heavy multitasking, but it gives up some clock speed for that. Both are Zen 5 on AM5 with 3D V-Cache, integrated Radeon graphics, DDR5 and 120W TDP, so the choice comes down to cores versus gaming speed.

• Choose the Ryzen 9 9900X3D if you game but also render, encode or compile for a living and want 12 cores and 24 threads in one AM5 chip.
• Choose the Ryzen 7 9800X3D if gaming is the priority and you want the highest frame rates with the simplest cooling and tuning.
