Up to 16 cores, 5 GHz and PCIe Gen 5.0 support

Intel’s upcoming 12th-generation Alder Lake-HX CPU lineup for enthusiast workstations and gaming laptops has leaked on video cardz† The lineup includes several SKUs focused on the fastest laptops for content creators and gamers

Intel 12th Gen Alder Lake-HX CPU lineup leaks: Designed for high-end workstation and gaming laptops with up to 16 cores, 5 GHz clocks and PCIe 5.0

The Alder Lake-HX series is Intel bringing the 12th generation desktop to the laptop segment in a BGA form factor. For this purpose alone, Intel will be using the Alder Lake ‘C0’ die, rocking a total of 8 P-Cores and 8 E-Cores. These chips come in the same package size as the desktop parts which are 45 x 37.5mm but have been thinned out to reduce the height from 4.4mm to 2.0mm.

Since these are based on the same silicon as the desktop parts, one should also expect a similar number of cores, cache sizes and clock speeds. A key feature is that Intel’s Alder Lake-HX CPUs will become the first PCIe Gen 5.0 platform for laptops, with a total of 48 PCIe lanes. These include 16 PCIe Gen 5, 20 PCIe Gen 4, and 12 PCIe Gen 3. As you might guess, these would enable better I/O capabilities than the existing Alder Lake-H series which offers just 28 PCIe lanes, including 16 Gen. 4 and 12 generation 3.

As for the other key feature of the Intel Alder Lake-HX series, we’re looking at full overclocking support for both the CPU and DDR5 memory. These are powered by an updated ETU (Extreme Tuning Utility), while XMP 3.0 profiles will be available on a wide variety of mobility HX platforms.

Finally, let’s talk about SKUs, there are a total of 7 starting at 8 cores and going all the way up to 16 cores. There isn’t a single SKU that doesn’t have E-cores enabled. What’s really interesting is that certain top-tier SKUs in each segment are ECC and vPRO compliant, while the 2nd-tier SKUs offer full memory and unlimited core overclocking, while the rest have limited core OC.

The Intel Core i9 segment, now coming to the SKUs, includes the i9-12950HX and i9-12900HX with 16 cores and 24 threads (8+8), with boost clocks up to 5.0 GHz, 30 MB cache and TDP figures ranging from between 55W (PL1) and 157W (PL2).

The Core i7 segment is the busiest with three SKUs, including the i7-12850HX, i7-12800HX and the i7-12650HX. The top i7 SKUs come with 16 cores but have 25 MB cache and up to 4.8 GHz clocks, while the 12650Hx comes with 14 cores and 20 threads (6+8) for a total of 24 MB cache with a clock speed up to 4.7GHz.

Finally, we have the entry-level Intel Alder Lake-HX Core i5 segment, which includes the 12-core i5-12600HX (4+8) and the 8-core i5-12450HX (4+4). These CPUs have a cache of 18 MB and 12 MB and the clocks are up to 4.6 / 4.4 GHz respectively. The only area where these chips are missing from the Alder Lake-H lineup is the 32-16 EU iGPU which is comparable to the desktop parts. We can expect these chips to land in several laptops in the coming months leading up to Computex 2022 and a formal announcement is expected on Inte’s Vision Event next week
