Intel’s upcoming line of 12th Gen Alder Lake-HX CPUs for enthusiast workstations and gaming laptops has leaked on Videocardz. The lineup includes a variety of SKUs designed to provide content creators and gamers with the fastest laptops.
Intel 12th Gen Alder Lake-HX CPU lineup leaked: Designed for high-end workstations and gaming laptops with up to 16 cores, 5 GHz clocks and PCIe 5.0
The Alder Lake-HX series is Intel’s 12th-generation desktop chips brought to the laptop market in a BGA form factor. For this purpose alone, Intel will use the Alder Lake ‘C0’ chip, which has a total of 8 P-Cores and 8 E-Cores. The chips will come in the same package size as the desktop part, measuring 45 x 37.5 mm, but have been thinned to reduce the height from 4.4 mm to 2.0 mm.
Since these are based on the same chips as the desktop parts, one should also expect similar core counts, cache sizes, and clock speeds. A key feature is that Intel’s Alder Lake-HX CPUs will be the first PCIe Gen 5.0 platforms 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 one might guess, these products will offer better I/O capabilities 4 and 12 Gen 3 compared to the existing Alder Lake-H lineup that only offers 28 PCIe lanes (including 16 Gen).

As for another important feature of Intel’s Alder Lake-HX series, we’re working on full overclocking support for the CPU and DDR5 memory. These will be implemented via an updated ETU (Extreme Tuning Utility), while XMP 3.0 profiles will be available for various mobile HX platforms.
Finally, let’s talk about SKUs, there are 7 in total, starting from 8 cores to 16 cores. There is not a single SKU that does not have the E-core enabled on the chip. What’s really interesting is that some of the top SKUs in each segment are ECC and vPRO compatible, while the second tier SKUs offer full memory and unlimited core overclocking, while the rest have limited core OC.
Coming to SKUs now, the Intel Core i9 segment will include the i9-12950HX and i9-12900HX with 16-core and 24-thread (8+8) designs, offering up to 5.0 GHz boost clock, 30 MB cache and TDP data range Between 55W (PL1) and 157W (PL2).
The Core i7 segment is the most crowded, with three SKUs including the i7-12850HX, i7-12800HX, and i7-12650HX. The top i7 SKU comes with 16 cores but with 25 MB cache and clocks up to 4.8 GHz, while the 12650Hx comes with 14 cores and 20 threads (6+8) with a total of 24 MB cache and clocks up to 4.7 GHz.
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 18 MB and 12 MB cache and are clocked up to 4.6/4.4 GHz respectively. The only thing these chips are missing from the Alder Lake-H lineup is the 32-16 EU iGPU, which resembles a desktop part. We can expect these chips to be used in several laptops ahead of Computex 2022 in the coming months, and an official announcement is expected at Inte’s Vision Event next week.
