Benchmarks & Specs

Last updated:
The Intel Pentium E6500K is a processor from an earlier era. Manufactured using the then-advanced 45nm process, it was a solid component. Its architecture, known as Wolfdale (Penryn), provided a reliable foundation for everyday tasks. A special feature was the K in the name Intel Pentium E6500K.

This stood for an unlocked multiplier, which overclocking enthusiasts appreciated back then. It allowed one to increase the processor's performance beyond the factory settings. For simple office applications or as the heart of a retro computer, this processor still performs well today. We were surprised at how consistently it has held up after all these years.

While it cannot compete with modern CPUs, it delivers solid performance for its intended purpose. The 2 MB Level 2 cache efficiently supported the workflows. Its maximum memory bandwidth was 21 GB/s.
  • Unlocked multiplier for overclocking
  • 45 nm manufacturing technology
  • Good performance for simple applications
  • Reliable for retro systems
