Why does Apple mobile SoCs have such high single core scores? Why doesn't Qualcomm chips also have such high scores?

Recommended Posts

Posted · Original PosterOP

Apple is always known to have really high single core scores on their A-Series SoCs. But why?

because Apple's SOC's are simply better than qualcomm's.

 

same thing with Intel. their IPC is just better than AMD's at the moment, that's why intel's single core performance is better than AMD's.....

I guess Apple had it's own ARM implementation and chips since the early versions of iPods Touch back in the days, and it's developing the software and the architecture from then, their architecture is simply better than Qualcomm, also they only develop high-end chips unlike others, however the differences in the last years started to shrink as Qualcomm development especially (can't say the same as other vendors) seems very fast in every market target

Theoretically, Apple SoCs simply have better cores.

 

However, without putting iOS on Snapdragon and Android on A series SoCs, there's no verification that the scores between the hardware (or software) platforms is consistant.

 

For all we know, Snapdragon cores could be twice as fast but inaccurate testing or a more bloated operating system doesn't show that.

Seems she was struggling

Something is wrong with this world.

It's because the execution units on Apple's A-Series SoCs are wider than most other CPUs implementing the ARM architecture. This means they can service more instructions at once.

 

While I don't have a block diagram, this is how many instruction types the A12 can do at once:

  • 6 Integer
  • 2 Load/Store
  • 2 branch calculation
  • 3 floating point

So basically 13 operations at once.

 

Compare this to the Cortex A75, which was used in Qualcomm's Snapdragon 845:

  • 2 Integer
  • 2 Load/Store
  • 1 Branch calculation
  • 2 Floating point
  • 1 floating point store

Or 8 operations at once.

Simple, they fake benchmarks, like Huawei did
