Intel “Raptor Lake” ES Posts 9.4% Higher Single-Core Performance Than “Alder Lake”

In what could be evidence of Intel pulling off a major generational IPC increase, Chinese PC enthusiast Extreme Player, with access to a Core i9-13900K engineering sample (ES), tested the chip on a handful synthetic tests, with the processor yielding significant performance gains over its predecessor, the i9-12900K. The most striking performance number has to be the CPU-Z Bench single-core test, which shows an impressive 9.41 percent increase over that of the i9-12900K.

The i9-13900K packs “Raptor Cove” performance coves, which Intel claims come with a generational IPC increase over the “Golden Cove” P-cores. The 9.4% performance increase could be a result of not just increased IPC, but also higher clock speeds (set at 5.50 GHz, the assumed maximum boost frequency of the retail processor). The multi-threaded CPU-Z Bench sees an incredible 46.34% performance increase. This stems from not just increased performance on the eight P-cores, but also the doubling in E-cores from 8 to 16. The E-core clusters also see a doubling in L2 cache sizes. The story repeats with Cinebench R23, with an incredible 13.53% single-thread performance increase, and a 40.25% multi-threaded performance increase.
