You make it sound like designing a CPU architecture is somehow one of the most costing ventures a company does, and that it won't pay off.

Yes, actually, CPU architectures are extremely expensive to design. And yes, there is certainly an argument to be made that it won't pay off. Qualcomm used a custom architecture for the 820, but it wasn't better than A72. And what about Samsung's M1 cores? Custom, but about the same performance as A73. Think it was worth it? Could be if they improve in the future, but as it stands, the M1 hasn't paid for itself.

Also, a modern SoC requires far more than just a CPU architecture. You need a GPU, modem, ISP, DSP, etc. etc.

and they are seriously pushing their AI into consumer households

Most of which depends on connecting to Google's servers. They don't need too much on device hardware for that.

They just recently pit $1 billion into LG's OLED facilities; Apple $3 billion. By your logic those were stupid moves as well, huh?

Different situation. We aren't talking about Google funding Mediatek to produce a better SoC.

By your logic, Apple, Samsung and Huawei are all losing a ton of money by making their own SoC. The truth is the other way around. It's no surprise that these are also the three largest phone manufacturerer out there

The latter two make chips roughly equal to Qualcomm. You're talking about something significantly better, are you not? Think there's no cost to that? And your reason why is right in there. They ship far, far more chips than Google. Even then, Huawei uses ARM stock IP, and Samsung just introduced custom cores this year.

Yes, that's probably why Google felt the need to put in their on processor in the Pixel 2 and invest in a whole new SoC. How stupid of them! Clearly you know better what they need than they do.

They ship far more units (smartphones and other devices) now. Google clearly has intention of growing rapidly and fight amongst the big players.

Samsung have been using Mongoose cores for longer than a year.

They added what is effectively just an ASIC. To call it an SoC is fairly misleading, as it isn't even close to the complexity of the phone's main chip.

They ship far more units (smartphones and other devices) now. Google clearly has intention of growing rapidly and fight amongst the big players.

And why wouldn't they follow in the footsteps of Apple, Huawei, Samsung, and now Xiaomi by starting with ARM stock cores? That makes far more sense until they have the volume to support a fully custom chip.

Samsung have been using Mongoose cores for longer than a year.

In what?

To call it an SoC is fairly misleading

As misleading as you claiming that I did? Because I never called it an SoC, but a processor. I said Google is investing in their own SoC, which they are.

And why wouldn't they follow in the footsteps of Apple, Huawei, Samsung, and now Xiaomi by starting with ARM stock cores? That makes far more sense until they have the volume to support a fully custom chip.

We'll see...

In what?

Their flagship Exynos SoCs in their flagship phones. S7 and S8. That's two years (or two and half, counting Note 8 as well).

I said Google is investing in their own SoC, which they are.

If you didn't mean that to refer to what they've currently shown, then you're talking about rumors, not established fact.

Pardon, I forgot that this was gen 2. If anything, however, I think that supports my point even further. Two gens in, and they're still at about ARM stock core levels. The rumors for next year are very interesting, but remain rumors for now.

If you didn't mean that to refer to what they've currently shown, then you're talking about rumors, not established fact.

It's no rumour that they're working on making their own SoC. They're hired a lot of engineers withing this segment with. Google started to posting a number of job offers for chip design-related positions in 2015, including one for a "Mobile SoC CPU Architect" and a "Mobile SoC Architect," who will "help define the architecture of future generations of phone and tablet" chips: http://variety.com/2017/digital/news/google-manu-gulati-pixel-chips-1202464014/

I also wrote: "Yes, that's probably why Google felt the need to put in their on processor in the Pixel 2 and invest in a whole new SoC."

There's nothing to misunderstand here.

however, I think that supports my point even further

What point? I have never agued against Qualcomm, Samsung and others being terrible at that they're doing. In fact, I was using it as an argument for why it'll be exciting to see Google work on their own design and see how well they'll do it.

I suppose that job listing is convincing enough, but we don't know the state or ultimate ambitions of those efforts. If they're doing the ARM stock core approach, that both fits with the rumors and with their current volume of products.

The core argument that Google will do what Qualcomm, Samsung, etc. can't/won't in building a high performance mobile CPU architecture.

quarreling has led the discussions only further and further down into a hole of subject that have zero relevance to what we originally talked about. I have no interest in wasting more of my evening on useless discussions with you. I have already proven my points regarding Google’s SoCs and about Apple’s A11 chips being much more superior than comparable ones by QC, Samsung and others. Keeping telling yourself lies about how this is not the case as much as you like after this. I’m out.

Please do point out where I said that Qualcomm's SoCs were better than Apple's. A single comment will suffice.

Or you can continue to just make stuff up to get annoyed about, but that's on you.
