Intel has announced its new 12th generation HX processors for mobile workstations, which will also serve as laptops.

The HX range consists of a pair of Core i9s, a trio of i7s and a pair of i5 chips, all of which have a base power of 55 watts and a maximum turbo power of 157 watts. Intel said that the design of the range is based on its desktop Alder Lake chips and optimized for laptops.

The game-focused i9-12900HX has eight performance and eight efficient cores, 30 MB L3 cache and a base p-core frequency of 2.3 GHz. The workstation-focused i9-12950HX is identical, but also supports ECC memory and vPro, and while the former is tagged as “unlimited kernel overclocking”, the latter has only memory overclocking.

The same differentiation exists for i7-12850HX and i7-12800HX, which retain eight times eight cores, but have 25 MB L3 cache and have a base P core frequency of 2.1 GHz and 2 GHz respectively. With two performance cores, the i7-12650HX comes with 24 MB L3 cache, limited overclocking capability and a 2GHz base frequency.

In the lower part of the HX range is the i5-12600HX which has four performance and eight efficient cores, 16 MB L3 cache, P-core base frequency of 2.5 GHz, while the 8-core i5-12450HX shares its core equally between performance and efficient, has 12 MB L3 cache and a base frequency of 2.4 GHz. i5-12600HX has vPro and ECC memory support.

Although the chips have graphics devices, Intel said that all devices would come with a discrete GPU, which includes Intel Arc. In tests with an Nvidia RTX3080, the systems beat three-digit frame rates Far Cry 6, Forza Horizon 5, Hitman 3, Riftbreakernand Total War: Warhammer III.

The HX range supports up to four M.2 devices – two of which are CPU-connected and one slot that supports PCIe Gen5 and Gen4, and a couple more PCH-connected storage that supports PCIe Gen4 – for a total of up to 16TB of storage. The memory capacity of the HX line has been increased from 64 GB on the H series to 128 GB DDR5 memory.

Intel said that the difference between the HX and its HK and H series announced earlier this year was behind the ability to handle big data and to quickly move that data within the system and out of it with the Thunderbolt 4.
