Snapdragon 865 is 83.54mm^2 (7nm) Apple A12 is 83.27mm^2 (7nm) Apple A13 is 98.48mm^2 (7nm+) Apple A14 is 88mm^2 (5nm) Not a very big difference. Remember, Qualcomm's chip includes a modem while Apple's does not (at present). Qualcomm has also been putting a lot of resources into other areas like neural processors. Their upcoming 888 claims 26 TOPS (vs 11 TOPS for Apple) Cache is a very common misnomer too. A14 has 8MB of shared L2. 888 has 4MB of shared L3 plus 1MB for the X1 core and 0.5MB per each A78 core. It also has 3MB of what they call DSU cache which serves as a kind of general cache for everything on the chip that needs to hit memory. That's actually 1.5MB more total cache than Apple offers.
