Intel squeezes desktop Alder Lake CPUs into laptops with Core HX-series chips

Intel's HX-series laptop processors bring the company's desktop CPUs into high-end, high-powered laptops.

Earlier this yr, Intel announced three iterations of its Twelfth-generation Alder Lake CPU structure for laptops: the U-series, which covers thin-and-light Ultrabooks, the P-series for thin-and-light workstation laptops, and the H-series for beefier workstations and gaming laptops with extra room for big processor followers and heatsinks.

Now, Intel is including yet one more sequence of chips: the HX series, designed for even sooner laptops. Regardless of sharing a letter with the H-series chips, the H and HX CPUs do not have quite a bit in frequent. The H-series chips are scaled-up variations of Intel’s laptop computer processors with beefier built-in GPUs, built-in Thunderbolt, and a built-in chipset controller on the identical bundle as the remainder of the CPU. The HX chips, then again, use the identical dies as Intel’s desktop Alder Lake chips, however are soldered to a laptop computer’s motherboard reasonably than inserted right into a CPU socket.

CPU P- and E-cores P-core clocks (Enhance) Base TDP Turbo TDP
Core i5-12450HX 4P/4E 2.4GHz (4.4GHz) 55W 157W
Core i5-12600HX (vPro) 4P/8E 2.5GHz (4.6GHz) 55W 157W
Core i7-12650HX 6P/8E 2.0GHz (4.7GHz) 55W 157W
Core i7-12800HX 8P/8E 2.0GHz (4.8GHz) 55W 157W
Core i7-12850HX (vPro) 8P/8E 2.1GHz (4.8GHz) 55W 157W
Core i9-12900HX 8P/8E 2.3GHz (5.0GHz) 55W 157W
Core i9-12950HX (vPro) 8P/8E 2.3GHz (5.0GHz) 55W 157W

These CPUs have increased TDPs than their H-series counterparts, with 55 W base TDPs as an alternative of 45 W and 157 W Turbo TDPs reasonably than the 95-to-115 W TDPs of the H sequence. The ability improve means these chips will run sooner for longer than H-series processors on the expense of upper energy consumption and warmth output. Nonetheless, our testing of those desktop chips means that the Core i7 and i9 processors will profit extra from the boosted energy limits than the lower-core-count Core i5 variations.

Being a scaled-down and repackaged desktop chip gives some advantages and downsides in comparison with common H-series laptop computer processors. On the constructive aspect, the Core i7 and Core i9 chips provide an extra pair of P-cores and eight effectivity cores, for 16 cores and 24 threads. So long as your laptop computer can deal with the additional energy necessities, these must be useful for CPU-heavy productiveness and rendering duties.

These processors additionally help PCI Categorical 5.0, although there’s not a lot of some extent to it but—present GPUs and SSDs do not use the brand new commonplace but, and will not for some time. Additionally they help reminiscence overclocking, the identical as their desktop counterparts, and the vPro-compatible variations help ECC reminiscence as properly.

The HX-series chips offer the same features (and drawbacks) of Alder Lake desktop chips, which means you do get PCIe 5.0 but you don't get built-in Thunderbolt.

Whether or not the drawbacks hassle you’ll rely upon what you are doing. The chips’ built-in GPUs prime out at 32 execution models (EUs), down from a most of 96 within the H-series CPUs. Laptops with HX processors are near-certain to incorporate devoted GPUs, which normally will not be a giant deal, however the CPUs’ lack of built-in Thunderbolt 4 connectivity is extra obvious. As much as two devoted Thunderbolt controllers might be added, however that will increase price and complexity.

The Core i7 and i9 HX-series chips might make some sense for individuals who want all of the CPU efficiency they will get in a laptop computer, however the oddball Core i5 HX choices are most likely finest prevented. They embrace simply 4 P-cores and both 4 or eight E-cores, not more than the common H-series chips, and at these core counts, they’re unlikely to profit a lot from their boosted TDPs.

Intel did not give a selected availability date for laptops with HX-series CPUs, however mentioned that “greater than 10 workstation and gaming designs” can be coming from the PC corporations “this yr.”
