Because Apple isn't playing the same game as everyone else. They have the money and clout to buy out TSMCs bleeding-edge processes and leave everyone else with the scraps, and their silicon is only sold in machines with extremely fat margins that can easily absorb the BOM cost of making huge chips on the most expensive processes money can buy.

Bleeding edge processes is what Intel specializes in. Unlike Apple, they don’t need TSMC. This should have been a huge advantage for Intel. Maybe that’s why Gelsinger got the boot.

Intel Arc hardware is manufactured by TSMC, specifically on N6 and N5 for this latest announcement.

Intel doesn't currently have nodes competitive with TSMC or excess capacity in their better processes.

Serious question, why don't they have excess capacity? They aren't producing many CPUs...that people want.

Because their production capacity is much smaller than TSMC, it's declined over the past few years, and their newer nodes are having yield issues.

Hard to have excess capacity when your latest fabs aren't able to produce anything reliably.

They don't even have competitive capacity for all their CPU needs. They have negative spare capacity overall.

Intel's foundry side has been floundering so hard that they've resorted to using TSMC themselves in an attempt to keep up with AMD. Their recently launched CPUs are a mix of Intel-made and TSMC-made chiplets, but the latter accounts for most of the die area.

I'm not certain this is quite as damning as it sounds. My understanding is that the foundry business was intentionally walled off from the product business, and that the latter wasn't going to be treated as a privileged customer.

no, in fact, it sounds even more damning because client side was able to pick whatever was best on the market, and it wasn't intel. Client side could to learn and customize their designs to use another company's processes (this is an extremely hard thing to do by the way) faster than intel foundry could even get their pants up in the morning.

Intel foundry screwed up so badly that Nokia's server division was almost shut down because of Intel Foundry's failure. (imagine being so bad at your job, that your clients go out of business) If Intel client side chose to use Foundry, there just wouldn't be any chips to sell.

> Bleeding edge processes is what Intel specializes in. Unlike Apple, they don’t need TSMC.

Intel literally outsourced their Arrow Lake manufacturing to TSMC because they couldn't fabricate the parts themselves - their 20A (2nm) process node never reached a production-ready state, and was eventually cancelled about a month ago.

OK, so the question becomes: TSMC could do it. Why can’t Intel?

They are trying … for like 10 years

Intel is maybe a year or two behind TSMC right now. They might or might not catch up since it is a moving target, but I dont think there is anything TSMC is doing today that Intel wont be doing in the near future.

Wasn't it cancelled in favor of 18A?

It was, but that only puts them further away from shipping product.

These days, Intel merely specializes in bleeding processes. They spent far too many years believing the unrealistic promises from their fab division, and in the past few years they've been suffering the consequences as the problems are too big to be covered up by the cost savings of vertical integration.

if you think intel has bleeding edge processes, that hasn't been the case for over 6 years ...

Like the brand new Mini that cost 600 USD and went to 500 during Black week.

The 600 mini is on the m4 with the anemic 10 core GPU. This is for grandama or your 10 year old.

The good one which is still slower than m4 max is 2200.

If you want the max you need at least a macbook pro starting at 3200 and if you want the better one with 128G RAM it starts at about 5k

No matter how few GPU cores the M4 has, it is still an extremely potent product on the whole.

Better than most of the pc's out there.

Do you mean subjectively because you find Mac pleasant to use? The $600 mini certainly isn't more performant than 85% of desktops.

> The $600 mini certainly isn't more performant than 85% of desktops.

The average desktop isn't exactly a gaming machine. But a corporate box or a low end home desktop with a Core i5 and using the iGPU.

Transistor IO logic scaling died a while ago, which is what prompted AMD to go with a chiplet architecture. Being on a more advanced process does not make implementing an 512-bit memory bus any easier for Apple. If anything, it makes it more expensive for Apple than it would be for Intel.
