None have been announced, but I doubt it.
The 7945hx3d is essentially a desktop 7950x3d except in a laptop form factor. That has several major downsides compared to laptop chips.
The 3 main downsides are:
- Most AMD desktop CPUs are divided into multiple smaller chips internally. This has the upside of making it cheaper and easier for AMD to scale CPUs to higher core counts, however the downside is that the communication between those multiple chips is somewhat power intensive, which is why most laptop CPUs are a single chip for better battery life.
- Most AMD laptop CPUs use the latest and greatest manufacturing processes (currently TSMC 4nm) to achieve maximum efficiency. Most AMD desktop CPUs on the other hand use slight older manufacturing processes (currently TSMC 5nm and 6nm) for cost savings.
- Most AMD laptop CPUs have resonably powerful integrated GPUs. Most AMD Desktop CPUs on the other hand expect that the user will be using a dedicated GPU and as such have much weaker integrated GPUs, forcing more users to buy a graphics module to get acceptable performance.
All together that means that a 7945hx3d would result in significantly worse battery life, higher heat output (more than the Framework 16’s current cooling system is rated for, likely requiring major changes), and crippled iGPU performance compared to the CPUs Framework currently offers.
It’s possible that Framework could offer it in the future, however I suspect for the time being they are likely focused on other things such as offering more GPU options.
