Apple marketing is vague, but it doesn't matter much. Given the nature of the performance claims they make, the i3 and i5 are not that far off. Consider this: the i3-8100B (Mac Mini CPU) scores around 980/3500 in GB5. The i9-9980HK scores 1200/7000 — that's up to 2 times faster in multi-core. Apple claims 3.5x performance increase from the i3, which would put it on par with fastest currently available desktop x86 chips.
Few more things to consider:
- Anandtech just did tests of A14 and the 5 Watt iPhone CPU is outperforming (single-core) the latest Intel desktop while being within the striking distance of new AMD Zen 3 CPUs. M1 is basically A14 but with more CPU cores and more thermal headroom
- Only 4 cores of M1 are high-performance cores, the other 4 are much slower cores optimized for power efficiency. It is essentially a quad-core CPU and should be compared to other quad-core CPUs. The additional efficiency cores will have impact comparable to hyper-threading on other CPUs
- Apple doesn't do hyper-threading because they don't need to — they have solved the problem by massively increasing instruction level parallelism of their machines
- This is just the low-end chip... just think about it, we have here a 15W low-end Mac chip that is basically on par in some performance metrics with 100+ watt desktop CPUs... while having GPU performance of a 25Watts discrete Nvidia unit. This is absolutely mind boggling
First things first - When comparing the M1, we should also compare it in terms of power envelope, which means that we need to compare the M1 mac mini, to the baseline M1, the i3 found at mackbook air to the m1 fanless macbook air, etc.
The reason is that every version of a chip is optimized for a different Voltage level, impacting performance abilities significantly, not to mention cooling effects, etc.
Moreover, the Mac mini's processor is an 8th generation Intel processor - Apple didn't update the mac mini with the latest Intel processor before making this comparison, so comparing it to the prev baseline Mac mini is a good marketing trick.
Also, if u really want to get into the Engineering feat Apple is claiming for itself, lets not forget that the manufacturing technology they used is at least 1.5 generations ahead of the manufacturing technology used to create the 8th generation i3 that the prev baseline mac mini had. the manufacturing technology alone gives u a lot more power efficiency products not to mention the increase in performance.
When u look at Apple's Mac mini page for example, in the CPU section, the numbers they are showing (comparing to the baseline Intel Mac mini..) is
up to 3.4x performance upgrade (on final cut pro - faster ProRes transcode for example..) but in Affinity Pro the numbers are 2.3X faster multicore in vector performance, so is it a simple 3.5X on all tasks/apps/stuff u do with a desktop computer? probably not, and lets not forget the fact that they control all the computing process - chip, OS, app - does all the performance upgrade come from the chip itself? app or OS optimization..? don't know and it's probably a really hard thing to say, and that's why the direct comparison between the chips is not that straightforward.
regarding Desktop chips or real Pro chips from Apple -
i think that the major step as already been done, basically the M1 is the same as the A14. i don't expect Apple to do another this big of a jump also at the high-end desktop, especially when u consider all of the above regarding manufacturing technology and the fact that High-end Macs are a bit more updated with the last Intel generations.
I do think that the biggest news from this Apple event was that the sleepy chip industry has awaken itself from Intel reign of status quo, and now us consumers will have a lot more options and hopefully better devices for less money.
I love the fact Apple kept the pricing the same, as we get a much better product as a whole for the same money which is great. Also, I love Apple products and their approach to what consumer products should be, and excited to see what this Optimization of Hardware and Software could do to a laptop. hopefully the Mac will be the iPhone of the Laptop/Desktop industry.
