The Guardian piece now does include a link to the paper cited - replacing the previous internal link. No mention that a change has been made though.

That’s a fair challenge. I think it’s a little different though - the SoC was one component of the iPhone - so full details of the competing product weren’t being shared. Plus when the relationship started volumes were small for both iPhone

Absolutely! Handing over your detailed product specifications and product plans to a direct competitor is inconceivable. I’m 100% convinced now that an Intel split into foundry and CPU vendor is inevitable. It’s a political if not a commerc

In this context the Gelsinger video clip in the article is fascinating. Sometimes companies fixate on one element of their strategy that has worked in the past. It seems that Intel had ‘always make x86 / backwards compatible’ as their

There was the infamous demo when they ‘forgot’ to mention a CPU was overclocked. Bit of a red flag for the culture that permits that. https://www.tomshardware.com/news/intel-28-core-cpu-5ghz,372...

Indeed and XScale was successor to StrongARM which I think was highest performing Arm design for a while. Sold to Marvell in 2006 right before the iPhone appeared. Intel then spent billions trying to make x86 commercially viable on mobile.

The CISC vs RISC point Ben makes is key here. Intel could have been a big player in mobile: it put too much focus on x86 though when it could have been making (its own or others) Arm based SoCs. Edit: not that Arm is necessarily RISC - but

Great piece but it seems that Ben doesn't quite finish joining the dots. If Intel is to have a successful foundry business at the cutting edge then its customers will be those firms that are designing cutting edge CPUs, SoCs and GPUs.

Your first para is correct but this doesn’t mean that Intel will become the TSMC of the west. Doing so needs not only huge amounts of investment but a massive change in the business model and by all accounts culture. Neither of these are a

My 'growth' comment referred to the laptop /desktop __market__ which medium / long term - which is what the investors will focus on - is clearly low growth. Intel's single quarter performance in that market is quite

Not sure what I didn't see. The CPUs are around 4x the everything else put together so to first order of magnitude Intel is a CPU business.

Agreed. Also there has been a tendency to see losing / turning down the iPhone as the pivotal moment but I think it was the years after that which were crucial. They relentlessly pushed x86 on mobile when it was clear there was little

The problem is that at the moment Intel only really have one business - selling CPUs for desktop/laptops and servers. In the latter market they are under severe pressure from AMD and Arm based CPUs. The former is relatively low growth.

This reminds me of an incident a long time ago when we had issues with Compaq 386’s overheating. I came back from holiday to be told that they had solved it by adding a bigger fan. When I finally saw the offending machines they had their co

It’s not RISC-V ‘gunning’ for RPi, it’s certain SBC manufacturers who think that a RISC-V board will enable them to compete with RPi. It may, but the success of these boards will largely depend on other factors. RPi has succeeded because o

Are you saying that only people with very good micro architecture knowledge are allowed to ask questions about the RISC-V ISA? Whilst the presentation of this as a ‘problem’ is debatable as may be some of the reasoning it doesn’t seem to m

That's Casey raising this issue not any preceding discussion or documentation of the decision.

I'm not qualified to comment whether this is a significant issue or not. What puzzles me though is that as RISC-V is an open source ISA there should presumably be discussion of pros and cons and documentation of the decision to use thi

The key point is that if you know how to grow your publication without Medium’s help then Ghost is a great option. I’ve been using Ghost for my newsletter for actuaries using Python and Medium’s distribution would add no value for me at all

This is a really interesting comment with which I have a lot of sympathy but disagree in large part. I too yearn for an updated ‘home computer’ but with powerful modern hardware! Firstly, I don’t think the PI’s can be seen to have failed. I

The barrier to a PI SoC is the non CPU components - which are proprietary to companies like Broadcom. I’m sure that RPi could happily license an Arm core - indeed they have with the Pico - and the existence or otherwise of RISC-V cores is b

On the subject of the iAPX 432 is anyone aware of an emulator? The only material I’ve seen is quite high level and doesn’t go down to ISA level.

Actually it’s not irrelevant. Lots of people choose between a Mac and Windows and the M chips up the competitive pressure on Intel and AMD to improve their offerings.
