A leaked CPU-Z screenshot has provided the first glimpse of an upcoming Intel Core Ultra processor, codenamed Arrow Lake-S. The image, believed to depict an engineering sample of a Core Ultra xx5K SKU, offers tantalizing details about Intel’s next-generation desktop platform, 15th gen.

The screenshot confirms several previously rumored specifications. Firstly, the processor boasts a 125W TDP and utilizes the LGA1851 socket. Notably, it features a hybrid architecture comprising 8 high-performance Lion Cove cores and 16 energy-efficient Skymont cores, totaling 24 cores and 24 threads. This confirms earlier reports that Intel has opted to forgo hyperthreading for this generation.

We think that the upcoming 15th gen launch could be a make-or-break situation for Intel, especially with a worrying amount of backlash online at the moment due to 13th and 14th-gen instability.

Additional features in Arrow Lake-S leak

The leaked image also suggests a boost clock speed exceeding 5.0 GHz, although the exact figure is obscured. Previous rumors have indicated a 5.7 GHz boost for the flagship 285K SKU, but this early engineering sample may not represent final performance metrics. Cache configurations have been independently confirmed by other sources. The processor is equipped with 2.4MB of L1 cache, 40MB of L2 cache, and 36MB of L3 cache.

While the screenshot lists the process node as 7nm, this is undoubtedly a placeholder, as Intel is expected to employ a more advanced node for the Arrow Lake compute die. Additionally, the absence of AVX-512 support is noteworthy, suggesting a potential shift in Intel’s instruction set priorities.

Lack of official confirmation

The appearance of this alleged Arrow Lake-S processor is particularly intriguing given the lack of official confirmation from Intel. The company has remained tight-lipped about the Core Ultra 200 series, despite the growing presence of LGA1851 motherboards at recent events like Computex. This suggests a strategic shift towards a September or October launch, coinciding with the introduction of the Z890 chipset.

As with any leak, it’s essential to approach this information with caution. While the screenshot provides compelling evidence of Intel’s progress, final specifications and performance details may change before the official product launch.
