You’ll likely see them in other products like lower end tablets or the Apple TV where lasering a core or two doesn’t matter.

Turns out the Apple tax means you're also buying the three chips thrown away to produce your one...

Waste is a factor in all production goods. Every fish you eat's price takes into account dealing with bycatch. Your wooden table's price accounts for the offcuts. It's the nature of making (or harvesting, or whatever) things.

Waste is an inherent inefficiency.

In silicon manufacturing, the inefficiency is actually pretty low specifically because of the kind of binning that Intel and AMD do, that GP was complaining about. In a fully vertically integrated system with no desire to sell outside, the waste is realized. In a less integrated system the waste is taken advantage of.

In theory capitalism should broadly encourage the elimination of waste - literally every part of the animal is used, for instance. Even the hooves make glue, and the bones to make jello.

That's not really an Apple tax though, that's a cost of doing business tax. It's not like Intel and AMD and everyone else aren't effectively doing the same exact thing.

Intel and AMD __literally__ sell those broken chips to the open marketplace, recouping at least some of the costs (or possibly getting a profit from them).

Apple probably does the same strategy PS3 did: create a 1-PPE + 8-SPE chip, but sell it as a 1-PPE + 7-SPE chip (assume one breaks). This increases yields, and it means that all 7-SPE + 8-SPE chips can be sold.

6-SPE-chips (and below) are thrown away, which is a small minority. Especially as the process matures and reliability of manufacturing increases over time.

I can confirm that 5000 desktop ryzen series has issues with turbo boost, basically if you disable turbo and stay on base clock then everthing is fine, but with turbo (CPB) enabled you get crashes and BSOD. I had this problem at work at my new workstation with ryzen 5900x. We RMAed it and new cpu works fine. From what i read it's pretty common problem, but it's strange that no on talks about it.

Can the turbo boost maximum frequency value be lowered a little in the BIOS to try and alleviate the problem?

I think yes, but if you buy cpu, you look at advertised speeds and you expect get them in your machine. From what i researched, to achive advertised clock frequencies you need to increase voltage to make it more stable. Some people reported silicon degradation after increasing voltages (it worked fine for week and then problems returned).

You can read more info on this forum post: https://community.amd.com/t5/processors/ryzen-5900x-system-c...

I am very interested in AMD's latest lineup (and bought a 5500U laptop that performs super well so far) but I am aware that on the PC front things can be a bit rockier and not always stable so such comments and articles help a lot.

Thank you.

Apple sells a 7 core and 8 core version of their M1 chips. Maybe Intel and AMD ship CPUs with even more cores disabled but it's not like Apple doesn't do this at all.

Apple doesnt sell chips at all. Next.

What are you talking about? Apple certainly sells chips -- you just have to buy an entire computer to get it.

Next?

There's no way they throw away that much revenue. Not even Apple is that committed to purity. I'm sure they have a hush-hush deal with another company to shove their chips in no-name microwave ovens or something.

Funny story about microwaves, theres basically only 2 main manufacturers. They're both in China, and you've never heard of them. But if you look at various brands in the US and take them apart, you'll see the only difference is the interface. The insides are literally the same.

The only exception to this are Panasonic microwaves.

Granted, a microwave with a half broken M1 in it would be awesome.

> The insides are literally the same.

To be fair, is there anything particularly revolutionary that could be done with a microwave (short of "smart" features)? They all function the same: shoot specific frequency energy into the (possibly rotating) chamber. It would make sense that the guts are just a rebadged OEM part.

I'd have guessed that brands would be able to differentiate themselves on even heating, how well the reheating sensors work, etc. But I guess not.

It's not that much revenue because the marginal cost of an individual chip is very low. Given that apple has plenty of silicon capacity, throwing away say 5-10% of chips that come off the line is likely cheaper than trying to build a new product around them or selling them off to some OEM who needs to see a bunch of proprietary info to use them.

No way; the half-busted chips go into low-cost products like the iPhone SE. It costs little to accumulate and warehouse them until a spot in the roadmap for a budget device arises.

The SE series uses the same chips, but cheaps out in other ways by going with older body, older camera, older screen.
