QEMU will let you emulate a particular cpu family, but you can't really tell it that you want a "486dx2 66 with 256kb of l2 cache". While 86box/pcem can't get 100% accurate, it's a lot closer than QEMU emulating the cpu family at your host cpu's full speed (or as close as QEMU can get with a single thread of opcode translation in the case of running other arches like ppc/hppa/sparc on a x64 host).
