Intel is preparing to launch a beastly new 16-core CPU

The specs of the upcoming Intel Alder Lake-HX mobile processors leaked before their release, providing some insight into what kind of performance we can expect from the new CPUs.

Intel Alder Lake-HX will be the first laptop platform with 16 cores and will soon appear in some of the best laptops on the market.


Intel is expected to introduce Alder Lake-HX at the upcoming Intel Vision event, which will take place from May 10 to May 11. The leaked specifications show a total of seven processors: two Core i9, three Core i7 and two Core i5. All of these, but especially the top of the lineup, will find their way into enthusiast laptops and workstations.

The Core i9-12950HX is the crown jewel of the lineup, with a whopping 16 cores and 24 threads; eight of the cores are P cores (performance) and the remaining eight – E cores (efficiency). We’ve already seen it benchmarked as far back as March 2022, but of course these tests may not be accurate at release.

As mentioned, Alder Lake-HX is the first mobile platform to offer 16 cores. According to the leak, the processor also has clock speeds of 2.3 GHz (base) and 5.0 GHz (boost) on its performance cores, as well as 30 MB of L3 cache. The base power of the processor is 55 watts, but the maximum turbo power goes all the way up to 157 watts.

The above processor is followed by the Core i9-12900HX, which has nearly identical specs, but the Core i9-12950HX is Intel vPro eligible, while the Core i9-12900HX is not. Intel vPro is Intel’s remote management technology, so basically these CPUs are likely aimed at mobile workstations.

The 55 watts of the Intel Core i9-12950HX is not unusual, as the entire lineup has the same processor base power and maximum turbo power. Compared to Intel’s previous mobility platform, Intel Alder Lake-H, that’s a 42 watt increase in boost power.

Alder Lake-HX also adds more PCIe lanes across the board and becomes the first mobile platform to support PCIe Gen 5.0. The increase in the number of lanes is quite significant, amounting to a total of 48 PCIe lanes: 16 Gen 5 lanes, 20 Gen 4 lanes, and 12 Gen 3 lanes versus the 28 (16 Gen 4, 12 Gen 3) offered by Intel Alder Lake-H.


In addition to PCIe Gen 5, Alder Lake-HX supports DDR5 memory with Intel XMP 3.0 profiles for overclocking purposes. It also comes with a feature called Dynamic Memory Boost. These CPUs are expected to offer excellent overclocking capabilities, including efficiency core overclocking. Intel Speed ​​Optimizer is also getting an update and the CPU also comes with Intel’s Extreme Tuning Utility technology. Intel says this applies to all HX processors, meaning they will all be overclock-friendly.

According to VideoCardz, where today’s leak comes from, Intel is going to put the entire Alder Lake silicon on a BGA package, and the package will be the same size as its LGA desktop counterpart (45 x 37.5 mm). However, it will be significantly slimmed down in height, going from 4.4mm to 2.0mm to fit comfortably into a much smaller space.

Actually, this isn’t the first glimpse of Alder Lake-HX specs we’ve had so far – we covered the first leak in April. Since the numbers align, there’s now a very good chance that the specs we see here are the real ones, and all that’s left is an official confirmation from Intel – which should be just around the corner.
