Using your best judgement on the gain in efficiencies and architecture, minding that Tflops is quite pointless as well. At which Tflop count more or less for the architecture of PS5/XB4 we would reach about 4x more performance than X1X?

We can do a very rough estimate with some basic math and assumptions. Let's assume GCN 1-2, 2-3, 3-4, and 4-5 all have a roughly 7.5% efficiency advantage while 5 to Navi (RDNA) has 25% as listed above by Pema. 

6 TF * 0.925 * 0.925 * 0.925 * 0.925 * 0.75 = 3.29 TF

So we're looking at roughly a 3.3 TF Navi GPU to reach similar performance to the XB1X, theoretically. 4x that is roughly 13.2 TF. 

This is all extremely rudimentary and depending on other hardware changes made by MS/Sony, I'd wager anything between 12 and 14.5 TF would be the range for 4x. 

That would be a "little" above the 10Tf ceiling a good portion is expecting, and 14.5Tf is above most expectations. But 12Tf is probably where the "majority" would expect both systems to hover about and would give the 4x gain of your calculation.
