Intel Showcases Hybrid CPU Architecture and Performance of Alder Lake Series Processors
Intel first introduces single-execution applications. The performance of a single P core (Golden Cove) with the same chip area and power package is 50% higher than that of the E core (Gracemont). The multi-execution performance of Intel’s hybrid chip design can be compared with 4 P cores. The core program is increased by 50%.
Intel explained that using 2 P cores + 8 E cores, the hybrid design does provide a 50% advantage over the standard 4P core design (12 execution sequence vs. 8 execution sequence), which is achieved under the same package and power constraints .
Intel delves deeper into Thread Director technology. Alder Lake series processors subdivide cores into specific IPC groups. Considering that IPC does not necessarily have the same workload or cores, it is obviously a set of solutions with a fairly existing mechanism. It is common to see average IPC or benchmark data for multiple workloads.
The scheduler of the actual operating system needs to adapt to the performance and efficiency of different architectures, which is where Intel Thread Director can perform its key functions. For example, in some scenarios, scheduling the execution sequence of smaller workloads can allow larger core scheduling to have better overall performance and efficiency.
Because Intel’s Alder Lake series processors are expected to become mainstream consumer-level platform hybrid x86 processor products, a lot of time and energy must be invested in the scheduling side to make the chips work efficiently. In the past period of time, Microsoft and Intel have established a very close cooperation, hoping that when the Alder Lake series processors and Windows 11 operating system are officially launched, they will bring stable performance to consumers.
