The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
24 cores crush heavy multi-threaded workloads like rendering.
Exceptional multi-threaded performance for rendering, simulation, and compilation workloads, with strong scaling across its 28 cores.
Gaming
Top-tier gaming performance, easily pushing high refresh rates.
Capable of high-refresh-rate gaming at 1440p/4K, but not optimized for gaming; modern high-end desktop CPUs often deliver better gaming performance for the money.
Virtualization
Excellent for complex virtualization and containerization.
Excellent for hosting multiple VMs or containers, thanks to high core count, large memory support, and robust I/O.
Efficiency
Efficient at idle, but can draw up to 250W under full load.
High 270W base and 324W max turbo power result in relatively high idle and load power compared to more efficient workstation or desktop alternatives.
