The P-series matches the H-series in base power with 45W across the board and 65W Turbo Power across the board. The hybrid architecture opens up the possibility for two types of mobile processors, the P-series, and the U-series. In previous years, Intel had only the H-series for mobile workstations and the G7-series for its thin and light series. Intel also announced a new P-series that sits between the legacy H-series and the U-series for ultra-mobile processing. I imagine if Intel configured the E-cores to take on extra threads, the processor would be much closer to the turbo power of 115W than the base power of 45W, resulting in less efficiency. What is also interesting to me about the P-cores and E-cores is that each P-core has two threads, and each E-core has one thread. It leads me to believe that Intel is putting a lot of confidence in its Thread Director to manage each core’s compute. I believe Intel used this ratio because it is the best ratio for performance while regulating thermals and power draw. What I found interesting is that the H-series has 8 E-cores and 6 P-cores, two more E-cores than P-cores. The H-series has a base power of 45W and a Turbo power of 115W for the i9 and i7 models and 95W for the i5 models. Not only does it tell us that the 12 th Gen is capable of 40% more performance over the last generation, but it also tells us that it has a better PPW over the competition. It then takes 11 th Gen benchmarks, which are similar to my benchmarks on DC, and compares the two with its 12 th Gen equivalent. I like Intel’s graph because it takes data from Apple’s own graph from its original M1 Max keynote back in October. The PPW of the M1 Max is impressive, to say the least, and from my owning testing, the PPW of the M1 Max outpaced Intel’s 11 th gen H-series but not in raw performance. The important aspect to look at in the 12 th Gen’s benchmarks is its answer to Apple M1 Max’s PPW.
