Intel “Bartlett Lake-S” Flagship Appears, Won’t Boot on Consumer Motherboards

Intel’s flagship “Bartlett Lake-S” processor—Core 9 273 PQE—has reached enthusiasts who are testing whether any consumer motherboard can boot the CPU and utilize its 12 P-Core gaming performance. According to Overclock.net user “Talon2016,” who managed to obtain a sample of the LGA-1700 flagship CPU SKU, the processor won’t boot using a consumer ASUS ROG Maximus Z790 Apex motherboard. These CPUs are designed for edge and embedded deployments with specialized platforms that lie outside the consumer sector. This high-TDP PQE variant has a base power of 125 W, powering a 12 P-Core variant with 24 threads and a base frequency of 3.4 GHz. This model can boost all 12 cores to 5.3 GHz, while a single thread can reach up to 5.9 GHz independently for tasks requiring intensive single-threaded performance. It is equipped with 36 MB of L3 cache and an integrated GPU with 32 EUs of Xe-LP graphics.

Unfortunately, regardless of the SKU or consumer motherboard choice, the platform will not work, and the CPU will not boot, as Intel has restricted “Bartlett Lake-S” to keep it away from consumers. Companies like ASRock have confirmed that the “Bartlett Lake-S” Core 200E will not be available for consumer motherboards and will only be used in the embedded and edge computer sector. This means you can technically buy and use this CPU for any Windows or Linux task, including gaming, but you will have to go through a process of acquiring an industrial-grade motherboard or a mini-PC that suits this platform. This means gaming support will be limited, as Intel explicitly will not bring any optimizations like APO/IPO to the platform for gaming. Instead, it will be treated as a generic x86-64 Intel CPU, just like any other processor. Extracting the maximum gaming performance could also be problematic, as there could be compatibility issues, given that Intel has envisioned other applications for this platform.
