Support up to 16 cores, 5 GHz and PCIe Gen 5.0

Intel’s upcoming line of 12th-generation Alder Lake-HX CPUs for workstations and laptops for enthusiasts has leaked to Videocardz. The offer includes various SKUs designed for the fastest laptops for content creators and gamers.

The 12th generation Intel Alder Lake-HX processor line has leaked: designed for high-end workstations and laptops for games with up to 16 cores, 5 GHz and PCIe 5.0

The Alder Lake-HX line is Intel bringing 12th generation desktops to the BGA notebook segment. For this purpose only, Intel will use the Alder Lake ‘C0’ matrix, which has a total of 8 P-cores and 8 E-cores. These chips will come in the same pack size as the 45 x 37.5 mm desktop parts, but are thinner to reduce the height from 4.4 mm to 2.0 mm.

Since they are based on the same silicon as desktop parts, a similar number of cores, cache size, and clock speed should also be expected. One of the main features is that Intel’s Alder Lake-HX CPUs will be the first PCIe Gen 5.0 platform for laptops, with a total of 48 PCIe lanes. They consist of 16 PCIe Gen 5, 20 PCIe Gen 4 and 12 PCIe Gen 3. As might be expected, they would provide better I / O capabilities than the existing Alder Lake-H line which offers only 28 PCIe lanes that include 16 Gene 4 and 12 Gene 3.

As for another significant feature of the Intel Alder Lake-HX line, we are looking at full overclock support for CPU and DDR5 memory. This will be enabled through an updated ETU (Extreme Tuning Utility), while XMP 3.0 profiles will be available on a wide range of mobile HX platforms.

Finally, let’s talk about SKUs, there are 7 in total, starting with 8 cores and going up to 16 cores. There is no SKU that does not contain E-cores enabled on the matrix. What’s really interesting is that certain top-tier SKUs in each segment are compatible with ECC and vPRO, while Level 2 SKUs offer full memory and unlimited overclocking cores while others have limited OC cores.

Now coming to SKUs, the Intel Core i9 segment will include i9-12950HX and i9-12900HX with 16 cores and 24 threads (8 + 8) design, offering boosted clocks up to 5.0 GHz, 30 MB cache and TDP numbers in the range between 55W (PL1) and 157W (PL2).

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

Finally, we have the initial segment Intel Alder Lake-HX Core i5 segment which includes 12-core i5-12600HX (4 + 8) and 8-core i5-12450HX (4 + 4). These processors have 18 MB and 12 MB cache, and clocks are rated up to 4.6 / 4.4 GHz. The only department where these chips are missing compared to the Alder Lake-H line is the 32-16 EU iGPU which is similar to desktop parts. We can expect these chips to land in several laptops in the coming months leading up to Computex 2022, and an official announcement is expected at Inte’s Vision Event next week.
