AMD Ryzen 7 9800X3D

What works

  • Best gaming CPU under $500 — V-Cache advantage over any 24-core Raptor Lake chip
  • Lower power draw (~120W gaming) vs 14900K's up to 253W peak
  • AM5 platform with longer upgrade path than LGA1700

What doesn't

  • 8 cores — multi-threaded rendering lags 14900K substantially
  • Higher price at $449-479 vs 14900K's current $300-350 street
  • V-Cache thermal sensitivity — sustained workloads that heat the cache can reduce performance

Intel Core I9 14900K

What works

  • 24 cores (8P + 16E) — 30-35% faster in video encoding and 3D rendering
  • LGA1700 platform maturity — lowest board prices, widest compatibility
  • 6.0 GHz P-core boost clock — competitive single-threaded when working set fits in cache

What doesn't

  • Gaming performance 20-30% behind 9800X3D in CPU-limited scenarios
  • Up to 253W power draw requires premium cooling and strong PSU
  • LGA1700 is end-of-life — no future Intel CPU support on this socket

Bottom line

Our pick: AMD Ryzen 7 9800X3D.
