Benchmarks & Specs

Last updated:
The Intel Core i9-9900X, manufactured using the 14-nanometer process, was based on the Skylake X Refresh architecture. For its time, it was an exceptionally powerful processor. As a high-end desktop chip, this Intel processor offered significant computing capabilities back then. Particularly noteworthy is its very good performance in games.

The X in its name already signaled an optimization for gaming at its launch. We can confirm: It still cuts a fine figure today.
  • High-End Desktop (HEDT) Processor
  • Very good performance in games
  • Large 19 MB L3 cache
  • Suitable for multitasking
With a generous L3 cache of 19 MB, the Intel Core i9-9900X ensures fast data access.

This is advantageous for the smooth processing of complex tasks. Its multitasking capability made it an excellent choice. Especially for creative applications, it was a very good fit. A maximum memory bandwidth of 85 GB/s also contributes to its robust overall performance. The Intel Core i9-9900X is no longer the latest model.

Nevertheless, it still offers a very reliable basis. It is well suited for systems that still need solid computing power. Many tasks can still be completed efficiently with it.
