That is a top layer shot of a flip-chip die. Every modern complex IC looks like that. Any time you see a pretty die shot with identifiable blocks of any kind of modern CPU or SoC, instead of a grid of balls, it's because someone has gone through the trouble of removing most or all of the metal layers which obscure all the circuitry. Otherwise it looks like that photo. Balls and power buses.
- rbanffy 6y agoThat makes a lot of sense - packing thousands of solder points around the chip as we did when a CPU had 40 pins is impractical now. This must also simplify timing and routing as you can always use the closest ball to the point you want to connect the die to the external world. Sad that the most beautiful parts are under all that stuff.
