AMD Ryzen 7 9800X3D vs Intel Core Ultra 7 265K
Verdict: The AMD Ryzen 7 9800X3D wins for gaming with 15-25% higher frame rates from its 96 MB cache (Tom's Hardware benchmarks) while the Intel Core Ultra 7 265K excels in multi-threaded work with 20 cores. Intel's integrated graphics add convenience but its smaller cache hurts in titles. Choose AMD for pure gaming rigs and Intel for mixed productivity.
Winner: AMD Ryzen 7 9800X3D
AMD Ryzen 7 9800X3D: 9/10
Intel Core Ultra 7 265K: 7.5/10

AMD Ryzen 7 9800X3D
What works
- 96 MB L3 cache delivers 15-25% higher gaming frame rates than non-X3D Zen 5 CPUs (per Tom's Hardware)
- Lower 120 W TDP runs cooler under sustained loads than 125 W Intel counterpart
- Strong single-thread performance with Zen 5 architecture
What doesn't
- Only 8 cores limits heavily multi-threaded productivity workloads
- No integrated graphics, requires discrete GPU
Intel Core Ultra 7 265K
What works
- 20 cores provide superior multi-threaded performance in rendering and encoding
- Integrated Arc graphics eliminate need for entry-level discrete GPU
- Newer Arrow Lake platform with improved NPU for AI tasks
What doesn't
- Smaller 30 MB L3 cache trails in gaming frame rates versus X3D chips
- Higher 125 W TDP requires stronger cooling solution
Bottom line
Our pick: AMD Ryzen 7 9800X3D.
