Notes
The Core i5-6400 features 4 cores and 4 threads with 65W TDP on Skylake, running at 2.7-3.3 GHz. This budget processor delivered entry-level performance during the quad-core era with DDR4 support. While severely limited by specifications and outdated by modern standards, it remains functional for basic office tasks. Often available at extremely low pricing for legacy system upgrades or minimal computing needs where basic quad-core performance suffices for light workloads.
