The a12 has about 3-4 times the number of transistors as i7-7700k. I know there are a lot of other on than the SOC core than the cpu for a12, but they still have a pretty large transistor budget. It was made with 7nm transistors vs 14nm that intel was using at the time when 7700k came out. Apple did a good job designing the chips, but TSMC is a huge part of why these chips are so good. For the longest time Intel manufacturing process was way ahead of anyone else which reflected in their performance. If I give you way more transistors I can probably make a better chip.
If I give you more cache, decoders, execution units etc. I can make a faster chip.
Also if you used all cores for sustained amount of time the intel would win out just because it can handle all that heat.
- nknealk 6y agoI think the dimension you’re missing is that the a12 also consumes significantly less power. While we don’t know exact numbers, the author speculates it draws about a tenth of the power as the i7.
- samfisher83 6y agoBecause its running at a much higher clock rate and its a much older process. The apple isn't running 4 big cores either.
- zamadatix 6y agoIt's the cache that makes this fast, not the higher clock higher voltage cores on an older process. Not that x86 particularly in 2018 is the pinnacle of perf per watt but the power dimension is non linear on some of these variables and this particular benchmark doesn't happen to gain much from it.
