Something to look forward to: Intel's high-powered Alder Lake-HX mobile platform is expected to be announced on May 10 at the company's Vision 2022 event. The chips will support PCIe Gen 5 and CPUs with up to 16 cores, both firsts for notebooks.

Rumors have been circulating for a while that Intel plans to release mobile CPUs featuring 16 cores, and today's leak confirms that. Videocardz has just published a slide containing the full specifications of the chipmaker's Alder Lake-HX lineup.

These chips will be desktop CPU dies installed on a BGA package, which will reportedly have the same length and width as desktop LGA (45x37.5mm), albeit with a reduced height from 4.4mm to 2mm.

Alder Lake-HX will also be the first mobile platform to feature PCIe Gen5, having a total of 48 PCIe lanes (Gen5x16 + Gen4x20 + Gen3x12). As a comparison, Intel's current flagship notebook platform, Alder Lake-H, features just 16 Gen4 lanes and 12 Gen3 lanes.

These new chips will also feature extensive overclocking functionality, supporting DDR5 with XMP 3.0 profiles, Dynamic Memory Boost, Efficient-core overclocking, as well as updated Intel Speed Optimizer and Extreme Tuning Utility.

Cooling these SKUs is going to be no easy task, as the entire lineup is rated for a 55W base TDP and a whopping 157W Turbo TDP, compared to Alder Lake-H chips that go up to just 45/115W.

Because these CPUs are based on desktop silicon, they will feature a significantly weaker iGPU, having a maximum of 32 GPU cores, compared to the 96 found on high-end AL-H parts. However, most of these chips will probably be paired with a dedicated GPU, so it isn't that big of a loss.

It's believed that Intel will officially announce the Alder Lake-HX platform on May 10 at their Vision 2022 event.

Am curious: For desktop ADL, PL2 = PL1. I assume it‘s not handled the same way for mobile but I also doubt the CPU will run at base frequency outside of the brief turbo window.

With 15min battery life. How Intel isn't able to make more power efficient CPUs, AMD gives gaming laptops with amazing battery life, they added E cores to 12th but they still get humiliated by Zen3 let alone Zen3+.

The 115w boost models already struggle if running any significant load for more then a few seconds. These things are gonna melt their chassis....

Alder lake mobile's battery life isnt bad, however if you limit TDP to get good runtime performance dips to zen 3 level.

Keyword: high-powered

A mere 3 OEMs carry Zen 3+ mobile laptops. That's a total of 10 laptops. Battery isn't everything, and effiency doesn't just mean a lower TDP. ADL is quite efficient when you stop focusing on heat and wattage at MAX load in benchmarks.
