Intel has announced its latest 12th Gen Alder Lake laptop CPUs at its press conference at CES 2022. The flagship Core i9-12900HK is also claimed to be the “fastest mobile processor ever created” and “the world’s best mobile gaming platform”.
Then new Core i9-12900HK processor features 6 Performance cores, 8 Efficiency cores, and a total of 20 threads. This CPU has a base power rating of 45W that can go up to 115W. There is also a 24MB of L3 cache. The Core i9-12900HK offers up to 28 percent faster gaming over its predecessor, the Core i9-11980HK. There is also a big jump in productivity tasks.
The Alder Lake CPUs use ‘Golden Cove’ architecture for P-cores and ‘Gracemont’ for E-cores. Chips are manufactured using a 10nm process. The company has developed a new scheduler called Thread Director to optimize workloads.
There are also other less powerful i7 and i5 models.
