Only bnxt and mcx support 50. Intel chips that do are 800 series, beyond ixl.

Also SFP28 ports are backwards compatible with SFP+ optics.

Re: 50Gbe
SFP28 (25gbit) is the way to go for density on x86 as it matches CPU bound bus architecture well. QSFP28 to 4*SFP28 offers the best price per port density both for interconnects (the DAC TwinAX 'squid' cables are cheap as chips) Network Stack Throughput through CPU on modern Intel x86 _64 even on perf tuned OS's tops out around 40Gbit locally so 50gbit ports don't make a lot of sence bar for specific use cases. Going faster means SmartNIC offloads, which are fine for certain use cases or if you just want to push packets without doing anything with them (i.e NIC to NVME etc, or switching).

There might also be some using multimode MTP cables but if there are, they're less common. Don't expect to get anywhere close to line rate with OpenBSD.

50Gbe
Hi folks! I wonder if OBSD supports 50Gbe network cards. And what is the cable standard to support such data transfers ? Thanks. -- The lion and the tiger may be more powerful, but the wolves do not perform in the circus
