Identical to the HP 801259-B21, the HP 801259-L21 CPU kit also centers around the Intel Xeon E5-2699 v4 processor and enhances the performance of the HP ML350 Gen9 series. With its 22 cores and the ability to process up to 44 threads simultaneously, this kit is perfect for environments that demand high performance, such as virtualized platforms, databases, and large-scale enterprise applications. The processor operates at a base frequency of 2.20GHz and comes with a 55MB cache, which significantly improves data processing speeds by providing quick access to critical information. Supporting a memory speed of 2400MHz and with a TDP of 145W, it combines performance with energy efficiency. The inclusion of this kit into ML350 Gen9 servers allows businesses to extend the systems' lifespan and capabilities, providing a cost-effective way to meet increasing computational demands without the need for complete server replacements.
