## Different Chips for Different Builds

The Core Ultra 7 265K’s 20 cores give it a clear edge in productivity tasks like video encoding and 3D rendering, roughly 38% faster in multi-threaded benchmarks. But the Ryzen 7 9800X3D’s massive 96MB 3D V-Cache remains the gold standard for gaming, since most games are far more sensitive to cache size than raw core count. If you’re building a dedicated gaming rig, the 9800X3D usually wins; for mixed creative and productivity work, the 265K pulls ahead.
