Process helps but have you seen benchmarks showing equivalent performance between the same process node? I think it’s less that ARM is amazing than the Apple Silicon team being very good and paired with aggressive optimization throughout the stack but everything I’ve seen suggests they are simply building better chips at their target levels (not server, high power, etc.).

> Our benchmark database shows the Dimensity 9300 scores 2,207 and 7,408 in Geekbench 6.2's single and multi-core tests. A 30% performance improvement implies the Dimensity 9400 would score around 2,869 and and 9,630. Its single-core performance is close to that of the Snapdragon 8 Gen 4 (2,884/8,840) and it understandably takes the lead in multi-core. Both are within spitting distance from the Apple A17 Pro, which scores 2,915 and 7,222 points in the benchmark. Then again, all three chips are said to be manufactured on TSMC's N3 class node, effectively leveling the playing field.

That appears to be an unconfirmed rumor and it’s exciting if true (and there aren’t major caveats on power), but did you notice how they mentioned extra work by ARM? The argument isn’t that Apple is unique, it’s that the performance gaps they’ve shown are more than simply buying premium fab capacity.

That doesn’t mean other designers can’t also do that work, but simply that it’s more than just the process - for example, the M2 shipped on TSMC’s N5P first as an exclusive but when Zen 5 shipped later on the same process it didn’t close the single core performance or perf/watt gap. Some of that is x86 vs. ARM but there isn’t a single, simple factor which can explain this - e.g. Apple carefully tuning the hardware, firmware, OS, compilers, and libraries too undoubtably helps a lot and it’s been a perennial problem for non-Intel vendors on the PC side since so many developers have tuned for Intel first/only for decades.

That was Zen 4, but it did close the gap:

Single thread performance is higher (so is MT), TDP is slightly lower, Cinebench MT "points per watt" is 5% higher.

We'll get to see it again when the 3nm version of Zen5 is released (the initial ones are 4nm, which is a node Apple didn't use).

Since it's unclear whether Apple has a significant architectural advantage over Qualcomm and MediaTek, I would rather attribute this to relatively poor AMD architectures. Provisionally. At least their GPUs have been behind Nvidia for years. (AMD holding its own against Intel is not surprising given Intel's chip fab problems.)

[acdha]

Yes, to be clear I’d be very happy if MediaTek jumps in with a strong contender since consumers win. It doesn’t look like the Qualcomm chips are performing as well as hoped but I’d wait a bit to see how much tuning helps since Windows ARM was not a major target until now.

I guess getting close to the same single thread score is nice. Unfortunately, since only Apple is shipping it is hard to compare if the others burn the battery to get there.

I suspect the others two, like Apple with the A18 shipping next month, will be using the second gen N3. Apple is expected to be around 3500 on that node.

Needless to say, what will be very interesting is to see the perf/watt of all three on the same node and shipping in actual products where the benchmarks can be put to more useful tests.

[cubefox]

Yeah, and GPU tests, since the benchmarks above were only for the CPU.
