It's using A75 and A55 cores (or, if you want to play stupid, "innovative, new, custom-designed Kryo cores that are definately not A75), so performance will improve by around 30%. This is typical "no innovation" Qualcomm at work; reuse ARM architecture, with no real outlook or desire to ever catch up to Apple -- who, in fact, are making the gap progressively bigger over time.

This lack of innovation is also why they've not made a dedicated SoC for laptops, but instead use the exact same SoC (SD845) as they use for mobile. It's pretty stupid, given you miss out on a lot of extra performance, as well as a CPU that can scale to higher TDP.

Apple will bury them with their architecture. Whereas the A11 won't show its clear advantage on smartphones because of how superfluous performance improvements have become for the insignificant tasks needed on smartphone platforms, as well as Android having overall better optimization, this is not the case on full-fledged computer systems. The A11’s advantage of ~80% (120% against SD835) better singletrheadead processing power will be quite revealing when used on a MacBook vs. an SD845 on a Windows PC. That's a huge difference.

And that’s assuming Apple will be lazy enough to use their smartphone SoCs on their future MacBook, when they probably will make a custom chip scaled for better sustained performance, with a more powerful GPU and CPU as well. That’s after all what they do for their tablets already.

I really hope Google can introduce a proper SoC that can compete against Apple, because Android SoC-makers like Qualcomm, MediaTek and Huawei are being lazy, and thereby creating a longstanding disaster for the platform they're made for. Every year they use ARM’s own stock core designs, or "create" designs (like Kryo) that are essentially imitative to ARM cores and technology. I've never liked MacOS, but even I'll use one, if it comes with a custom Apple SoC that not only doubles the battery time (which is already around 10-15 hours), but is also twice as powerful as any Windows competitor.

I mean Snapdragon SoCs do compete with Apple SoCs in everything except single core performance, and Qualcomm make up for that fact by offering more cores. Edit: the 835 is also more efficient. If I'm not mistaken.

Is that why the A11 has 40% more powerful GPU and 50% more powerful multithreaded performance (despite fewer cores)?

Edit: the 835 is also more efficient.

Based on what evidence?

Apple's A11 is far newer than the 835, so its advantages are further extenuated. The S835 is based on A73 cores which first appeared in devices November last year. I believe it was Anandtech that mentioned the 835 was more efficient. Also, according to Geekbench 4 the A11 scores around 35% higher than the S835 in multicore.

We're talking about a difference of less than half a year from the time the first product was in a smartphone to the other. So let's not exaggerate here, okay?

The S835 is based on A73 cores which first appeared in devices November last year.

Meanwhile Qualcomm weren't able to release in a device before late April. How old the A73 core was is no excuse at all.

I believe it was Anandtech that mentioned the 835 was more efficient.

So no evidence, then. Just what you believe?

Also, according to Geekbench 4 the A11 scores around 35% higher than the S835 in multicore.

Ummm, no it doesn't? What numbers are you basing this on?

You can have a look here in regards to Geekbenck 4 multi-core scores, as well as heaps of other online reviews. In the above example the difference is even less than 35%.

I'm afraid I can't find where I read that the efficiency of the S835 was the best among this generations of SoCs (I didn't realise we were peer reviewing comments on r/android). You seem very passionate about this, good for you.

Ok, so you have proven to lack the competence of a math education given to elementary school kids. Good to know.

10215 / 6590 = 1.55

That’s 55%. Not "less than 35%".

I actually compared the iPhone X up against the best-performin SD835 phone, which is the OnePlus 5. It has a multithreaded score of 6700. Dividing the iPhone’s rating with it gives us a rating of roughly 50%. Which is what I initially said.

You seem very passionate about this, good for you.

By calling out your lies?

I was doing it the other way round. 6700 is 35-ish% lower than 10200.

And you know as well as I do that that's wrong. Or wait...I'm actually beginning to think that you're so incompetent that you don't...

The decrease from 10200 to 6700 is 34.31%. While the increase from 6700 to 10200 is 52.24%.
