AMD Ryzen 9 9950X3D
What works
Best gaming CPU available — V-Cache stacking on Zen 5 leads all competitors
Strong single-core IPC for lightly threaded professional workloads
AM5 platform maturity and long-term upgrade path
What doesn't
$699+ — premium pricing for AMD's V-Cache halo product
Lags in fully multi-threaded rendering vs 285K's core count
No E-cores — background task efficiency lower than Intel's hybrid design
Intel Core Ultra 9 285K
What works
24 cores (8P + 16E) — substantial advantage in fully multi-threaded rendering and encoding
Arrow Lake's E-core improvements over Raptor Lake — more capable background task handling
LGA1851 ecosystem maturing quickly
What doesn't
Arrow Lake single-core IPC improvement over Raptor Lake was modest at launch
Bottom line
