Look for "Control-Flow Enforcement Technology" in the Intel cpu details
page on ark.intel.com. Yes it needs to be gen11 or newer.

AMD does not have it yet.

Cheapest way is probably the N100-based mini PCs (not speed demons but
fairly acceptable and they're really cheap).

For laptops, Thinkpad T14 are fairly common amongst developers.
(T14 g2 has gen11 CPUs, all cores the same - T14 g3 has gen12, mix
of performance + efficiency cores).
