Core Ultra 7 265KF

This might be our first look at Arrow Lake-S carrying an official name.

The upcoming Arrow Lake-S processor, listed as Core Ultra 7 265KF, is the first next-gen Intel CPU to leak. The SKU is equipped with 8 Performance cores and 12 Efficient cores, providing a total core count of 20. As we know, Lion Cove and Skymont architectures do not support hyperthreading, so the thread count will also be 20.

According to the detailed benchmark data, the CPU was tested on MaxSun’s new MS-iCraft Z890 Pacific motherboard , and it is very likely that the company tested this CPU themselves. This is one of the first LGA-1851 socket-based boards, and the Z890 chipset is the most capable one in the new series.

According to the detailed Geekbench output, the CPU was running at an average clock of 5405 MHz (minimum: 4841 MHz and maximum: 5484 MHz). Therefore, it is safe to assume that the maximum boost clock for P-Cores is 5.5 GHz.

The new SKU is part of the Core Ultra 7 series, so it makes sense to compare it to the last-gen Core i7, the 14700K. The 265KF is clearly faster in single-core performance, but the gap is only 6% in favor of the Arrow Lake-S CPU. Additionally, the new processor is 23% slower in multi-threaded tests. However, when comparing the 265KF to the 14600K, these figures are +12% and +1% respectively.

Rumors suggest that Intel will launch its Arrow Lake-S series in October. Full disclosure of the new SKUs is expected in September at the Innovation event. This indicates that qualification samples with the final SKU name are likely already available to board partners.
