The biggest die shrink in recent times was probably Intel's 22nm jump to FinFET (Global Foundries made a decent jump at 14nm, but it couldn't save bulldozer). Rather than the usual 50-70%, Intel claimed transistor density DOUBLED. Haswell got a very modes (<10%) performance improvement and an equally modest 10% lower power at load (though almost 25% at idle). Sandy Bridge did much better in performance (up to 40% in some benches) and also did decently well in power consumption despite using the same node. AMD saw massive increases with Zen on the same 12nm node. The also saw almost 20% IPC increases from Zen 2 to Zen 3 despite both being on the same N7 node If anything, history shows that node shrinks are always overrated at improving power and performance.
