The recently uncovered Barlett Lake CPU, specifically the Intel Core 9 273PQE, has been showcased on an LGA 1700 motherboard. The question on many enthusiasts’ minds is: does it function properly?
First Look at the 12-Core P-Core Only Intel Core 9 273PQE CPU on LGA 1700 Motherboard
Although the Bartlett Lake CPUs are primarily tailored for industrial applications rather than consumer use, they still demonstrate compatibility with standard LGA 1700 motherboards. Previous leaks have revealed details about all twelve WeUs of the P-Core-only Bartlett Lake processors. Notably, the Intel Core 9 273PQE stands out as the flagship model equipped with an impressive twelve Performance cores.
In comparison, the consumer-focused Raptor Lake Refresh lineup features a maximum of eight Performance cores, even in its top-tier processor, the Core i9 14900K/KS. Additionally, the Bartlett Lake series deliberately omits Efficient cores, a significant distinction from the Raptor Lake offerings. For those curious about the chip’s performance legitimacy, recent developments reveal concrete success:

User @wxnod shared a striking image of the Intel Core 9 273PQE installed in an LGA 1700 motherboard. This early engineering sample displays its Batch Code “X544L164″and S-Spec Code “SA4Q9″on the Integrated Heat Spreader (IHS).The processor impressively boasts a turbo boost clock of up to 5.9 GHz and features a sizable 36 MB L3 cache, aligning with previously leaked specifications.
The motherboard observed seems to be a consumer model compatible with the LGA 1700 socket, although its specific model remains unidentified. However, it’s reassuring that the Bartlett Lake processors, with proper BIOS support, should operate seamlessly on compatible motherboards.
Industry insiders suggest that some retailers may offer these CPUs to DIY builders, despite Intel’s decision not to distribute them through conventional channels. It raises the question of what could have been if Intel chose to release these P-Core-only processors to the broader consumer market. Even the 10-core Core 7 253PE competes effectively against 14-core Raptor Lake CPUs, indicating that the 12-core variant will likely excel in multi-threaded performance.
