12th Gen Intel Core i9 12900H | Review
Launched in January of 2022, 12th Gen Intel Core i9 12900H is a High-end processor for laptops powered by 6 performance cores with 12 threads and 8 efficiency cores with 8 threads. The performance cores have a base clock of 2.5 GHz and a boost clock of 5 GHz the efficiency cores, on the other hand, have a base clock of 1.8GHz and a boost clock of 3.8GHz. The i9 12900H is based on Intel’s 10 nm architecture with this the 12th Gen CPUs see an average IPC gain of 19 percent the higher IPC allows the Alder lake CPUs more performance at the same clock speed. The TDP of this Chip as specified by intel is 45 watts and can go up to 115 Watts (PL2) that being said most laptops will be utilizing 60 watts (PL1) for the performance boost. It also has support for new faster DDR5 memory of up to 4800MHz and low power LPDDR5 5200MHz while also supporting DDR4 memory of up to 3200MHz and low power LPDDR4X 4267MHz. Other Key Features Include Intel Iris Xe Graphics G7 96EUs (Alder Lake), and support for USB 4 (40Gbps).
In terms of performance, the 12th Gen Intel Core i9 12900H compared to its 11th Gen counterpart the 11900H according to Intel sees a 13% higher performance increment in 1080p gaming and 30% better performance in the Blender benchmark. Now if we were to compare the i9 12900H vs Ryzen 9 6900HX we are expecting intel with its new big little design to take a lead in both single and multi-core performance by 5-10 percent.
