AMD Ryzen 7 9800X3D

What works

  • 15–25% faster in gaming across CPU-limited titles
  • 96 MB L3 V-Cache delivers the best 1% low frame rates in the industry
  • AM5 socket with confirmed forward compatibility roadmap

What doesn't

  • 3D V-Cache limits overclocking potential compared to non-X3D chips
  • Runs hotter under sustained all-core workloads due to V-Cache stack
  • Overkill for 4K gaming where GPU bottlenecks before CPU

Intel Core Ultra 7 265K

What works

  • $394 launch price — $85 cheaper than the 9800X3D
  • 10–15% faster in multithreaded productivity workloads
  • Arrow Lake's hybrid architecture improves efficiency vs Raptor Lake

What doesn't

  • Arrow Lake's gaming IPC disappointed at launch vs Zen 5 X3D
  • LGA1851 socket history suggests limited upgrade path
  • 30 MB L3 cache shows its limits in cache-hungry game titles

Bottom line

Our pick: AMD Ryzen 7 9800X3D.
