An engineering sample (ES) of an Intel Core Ultra "Arrow Lake-S" desktop processor has been leaked, with impressive benchmark scores. The processor reportedly scored 1143.2 points in the single-thread benchmark and 12922.4 points in the multithreaded benchmark on CPU-Z Bench.
Comparing these scores to the Intel Core i9-13900K reference scores on CPU-Z, the single-thread benchmark score is 26.71% higher than that of the i9-13900K, while the multithreaded score is 22% lower.
It is unclear which specific model of the "Arrow Lake-S" processor this ES is, whether it is the top SKU with an 8P+16E core configuration or a mid-tier Core i5 SKU with a 6P+8E configuration. In the single-threaded test, the IPC of one of the chip's "Lion Cove" P-cores outperforms one of the "Raptor Cove" P-cores of the i9-13900K reference score.
It is important to note that Hyper-Threading does not play a role in the single-threaded test, but could impact the multithreaded test. The "Lion Cove" cores lack HTT support unlike the "Raptor Cove" cores, and the i9-13900K is a 24-core/32-thread processor.
The "Arrow Lake" processor features up to 8 "Lion Cove" P-cores and up to 16 "Skymont" E-cores. Intel claims to have achieved a significant IPC gain with the "Skymont" E-cores, bringing its performance in line with past-generation P-cores like the "Raptor Cove" or "Golden Cove."
