Alder Lake HX processor specifications revealed – up to 16 cores and PCIe 5.0 support


Intel will soon unveil its latest mobile series, but for now Alder Lake HX processor specifications Disclosure Has been. The new professional platform has important capabilities.

The blue giant plans to use the full Alder Lake desktop silicon in the BGA package. One of the slides confirms that the BGA package has the same dimensions as the desktop LGA (45 × 37.5 mm) and the only difference in height will be reduced from 4.4 mm to 2.0 mm.

But the Alder Lake HX series is more than just big, it will form a new 55-watt professional class that promises higher performance. In this series, the number of cores, thermal power and the number of PCIe lines have increased, and we even see the activation of PCI Express Gen 5.0 in this family. In addition, up to 48 PCIe lines are available in Gen 5.0 x16 + Gen 4.0 x20 + Gen 3.0 x12, which is higher than the Alder Lake H with Gen 4.0 x16 + Gen 3.0 x12.

Specifications of Alder Lake HX processors

Alder Lake HX of course supports overclocking. There is also support for DDR5 memory with XMP 3.0 profiles along with a new feature called Dynamic Memory Boost. Overclocked cores, Speed ​​Optimizer and updated Extreme Tuning Utility are also included. Intel claims that all HX models support overclocking.

Compared to previous rumors, the specifications of this series have not changed. We see 16 cores and boosts up to 5.0 GHz in at least two models. All HX chips, however, have a base heat of 55 watts and a 157 watt boost, which is 42 watts more than the Alder Lake H series. Also, due to the use of desktop silicon in the CPU, the number of graphics cores has been reduced to 32 or 16 units of the model.
