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

The upcoming 12th Gen Intel Alder Lake-HX line of processors for gaming workstation and laptop enthusiasts has been leaked on Videocardz. The range includes a variety of SKUs designed for the fastest laptops for content creators and gamers.

Leaking range of 12th generation Intel Alder Lake-HX processors: designed for high-end gaming workstations and laptops with up to 16 cores, 5 GHz and PCIe 5.0 clocks

The Alder Lake-HX line is Intel introducing 12th generation desktop matrices to the BGA segment of laptops. For this purpose alone, Intel will use the Alder Lake “C0” die, which has a total of 8 P cores and 8 E cores. These chips will have the same package size as the desktop parts that are 45 x 37.5 mm. but they have been thinned to reduce the height from 4.4 mm to 2.0 mm.

Since they are based on the same silicon as the stationary parts, a similar number of cores, cache sizes, and clock rates should also be expected. One of the main features is that Intel Alder Lake-HX processors will be the first PCIe Gen 5.0 platform for laptops to offer a total of 48 PCIe lanes. These include 16 PCIe Gen 5, 20 PCIe Gen 4, and 12 PCIe Gen 3. As you can guess, these would allow for better I / O capabilities than the existing Alder Lake-H lane, which only offers 28 PCIe lanes, including 16 Gen. 4 and 12 Gen 3.

As for another salient feature of the Intel Alder Lake-HX lineup, we’re looking at full overclocking support for both the CPU and DDR5 memory. This will be possible thanks to the updated ETU (Extreme Tuning Utility) tool, while XMP 3.0 profiles will be available on many different HX mobile platforms.

Finally, let’s talk about SKUs, there are 7 SKUs in total, which starts with 8 cores and ends with 16 cores. There is not a single SKU that does not contain E cores on the die. What’s really interesting is that some of the top-level SKUs in each segment are ECC and vPRO compliant, while the second-tier units offer full memory and unlimited core overclocking, while the rest offer limited core OC.

Now for the SKUs, the Intel Core i9 segment will include the i9-12950HX and i9-12900HX models with 16 cores and 24 threads (8 + 8), offering boost clock speeds up to 5.0 GHz, 30 MB cache and TDP values ​​ranging from 55 W (PL1) up to 157 W (PL2).

The Core i7 segment is the most crowded with three SKUs which include the i7-12850HX, i7-12800HX, and i7-12650HX. The best i7 SKUs have 16 cores but have 25MB cache and clock speeds up to 4.8GHz, while the 12650Hx comes with 14 cores and 20 threads (6 + 8) for a total of 24MB cache clock speeds of up to 4. 7 GHz.

Finally, we have the core 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 processors come with 18MB and 12MB cache memory and are clocked up to 4.6 / 4.4 GHz respectively. The only department that lacks these chips compared to the Alder Lake-H line is the 32-16 EU iGPU, which is similar to the stationary parts. We can expect these chips to land in a handful of laptops in the coming months, leading to Computex 2022, with an official announcement expected at Inte’s Vision Event next week.
