Don’t trust any silicon manufacturer’s marketing department. Let the processing and battery life benchmarks and real world tests do the talking.

AMD’s CPUs are faster and more power efficient on the same process node. (i.e. 5nm vs 5nm)

Apple just has a big budget to buy out TSMC process nodes a generation early, their designs and architectures aren’t actually faster or more power efficient than AMD’s x86 cpus.

Iirc the die area for Apple’s chips are also a lot larger and that’s expensive. It’s a lot easier for them to tank that cost because they are building them for themselves rather than selling them to vendors who manufacture products like AMD.

Yeah, Apple’s vertical integration and volume is enviable.

Am I blind? I don’t see any information in there to draw any conclusions about power efficiency. The little information that I do see actually seems to imply the apple silicon chip would be more efficient. Help me out please?

Both chips are 20w class cpus, but the AMD cpu is much faster.

Apple CPUs don’t report wattage, so it’s a bit tricky to measure actual power consumption, but I can’t imagine the AMD cpu uses 50% more power under load.

The Apple CPU might score some wins for idle power consumption though, considering the optimizations in MacOS, and the focus on power consumption across the whole system design.

24 threads at 2.00 GHz vs. 8 threads at 0.66 GHz with a 40% difference in TDP. The AMD chip may draw more power, but has much higher performance. Simplifying things, it can perform 9x the operations as the Apple silicon for only 1.4x the power draw.

Minor nit, but I believe that AMD CPU is 4nm

I believe both M2 and Zen 5 use 4nm. 4nm is just a slightly improved 5nm, though. It’s the same process node, not an entirely new process node like 3nm.

But then Apple would have to drop it’s prices by 40% so people would keep buying.

But that would make it accessible to commoners! *gasp*
