A new job listing lends more credence to rumors that Intel will ditch its multi-architecture chip designs for future CPUs.
Intel is searching for a senior CPU verification engineer within its Unified Core team, based in Austin. "In this role, you will be responsible for driving and executing the functional correctness of CPU logic designs through rigorous pre-silicon verification methodologies," the ad says.

Through a combination of performance and efficiency (and more recently, low-power efficiency) cores, Intel has spread the processing load differently to traditional mono-architecture chip designs, like its own predecessors and AMD's Ryzen CPUs. But mid-2025 rumors suggested that, after its Nova Lake successor, Razer Lake, Intel would return to a unified chip design using a single CPU architecture.
The purpose of Intel's split architecture design was to borrow from the big.LITTLE engineering approach of mobile CPUs and leverage weaker cores when energy efficiency was more important, and more-powerful cores when performance was required. Although it has shown impressive multi-threading performance in productivity apps, Intel's gaming performance has struggled, and its latest desktop entries failed to push the performance envelope much.
There is a lot of added complexity in a multi-architecture chip design. Intel employs a specialized Thread Director that dictates which cores are employed for which tasks alongside the operating system. Nova Lake looks set to be very capable, and Razer Lake perhaps even more so, leveraging Intel's future advanced process node technologies. But beyond that? Whoever gets this job may be working on a more unified design.
That would mean a very different Intel CPU than we've seen in recent years. To enhance performance there, Intel has relied on increasing the quantity of efficiency cores, with a suggestion in Nova Lake that there could be as many as 32, alongside 16 performance cores.
Returning to a unified core design would give Intel extra room on the chip for more performance cores, but it would be a complete redesign and layout change from its recent and near-future efforts. Whatever this future unified chip ends up being, though, it won't launch before 2030.
