1. Does any of the newer (post-Raptor Lake) consumer (i.e. non-Xeon) processor-chipset combinations support x4x4x4x4 bifurcation??
2. How about Xeons?
3. Is x4x4x4x4 bifurcation support anywhere on Intel's roadmap?

The support engineers aren't going to provide an answer to the third question; they are not allowed to speculate on future features and schedules. If you really need an answer, you will need to contact your local Field Support Engineer (FSE).
Hope this helps,

Hi Aqualung,
Thank you for posting in the Community!
Just to add, both the 13th Generation Intel® Core™ and Intel® Core™ 14th Generation Processors are compatible with Bifurcation. Detailed information on bifurcation can be found on page 140, within Table 51 of the datasheet. However, this feature is not mentioned in the datasheet for the 12th Generation Intel® Core™ Processor. It is also important to consider the following for Bifurcation function:
- To determine if CPUs/Chipsets support Bifurcation, it is important to identify motherboards that offer PCIe Bifurcation by reviewing the specifications provided by the manufacturers or by consulting the motherboard's user manual.
- The Bifurcation Feature is generally a function of the motherboard's chipset, not the CPU. It facilitates the splitting of PCIe lanes on the motherboard and is configurable via the BIOS settings.
- For comprehensive datasheets of the processors, we encourage you to visit our Technical Resources section for Intel® Core™ Processors.
Best regards,
Dean R.

I was inquiring about specifically x4x4x4x4 bifurcation for processor-chipset combinations, and I strove to formulate my questions in the clearest manner possible; as such, I see myself compelled to assert that I have not (yet) received a straightforward answer, hence you may want to re-read the OP.
