They can be made from large wafers. A defect typically breaks whatever chip it's on, so one defect on a large wafer filled with many small chips will still just break one chip of the many on the wafer. If your chips are bigger, one defect still takes out a chip, but now you've lost more of the wafer area because the chip is bigger. So you get a super-linear scaling of loss from defects as the chips get bigger.
With careful design, you can tolerate some defects. A multi-core CPU might have the ability to disable a core that's affected by a defect, and then it can be sold as a different SKU with a lower core count. Cerebras uses an extreme version of this, where the wafer is divided up into about a million cores, and a routing system that can bypass defective cores.
There’s an expected amount of defects per wafer. If a chip has a defect, then it is lost (simplification). A wafer with 100 chips may lose 10 to defects, giving a yield of 90%. The same wafer but with 1000 smaller chips would still have lost only 10 of them, giving 99% yield.
As another comment referenced in this thread states, Cerebras seems to have solved by making their big chip a lot of much smaller cores that can be disposed of if they have errors.
Indeed, the original comment you replied to actually made no sense in this case. But there seemed to be some confusion in the thread, so I tried to clear that up. I hope I’ll get to talk with one of the cerebras engineers one day, that chip is really one of a kind.
I have a pixel 6 pro, works great
Never had problems with the microphones, and calls are extra clear because they do some ai nonsense to upscale the audio coming into the phone
My 2 main gripes are:
The modem, I have issues with reception in the strangest locations, I can have direct line of sight to 3 different cell towers and still get stuck on edge till I hit the "Fix connectivity" button in settings, but when it is working (which it does 95% of the time), works great
The camera, amazing photo quality, videos look great, I have nothing against image quality. But the videos this thing takes are MASSIVE, even with HVEC on, a 50 second video can weigh over 300mb. Not sure what's up with that.
Oh also the main shooter camera is mechanically separated from the rest of the phone, so if you shake the phone or whip pan it too hard, you can hear it rattle.
Overall 9/10 though!
I hear the pixel 7 has a better modem
This makes sense for the small stop and go trucks for around town, but I'm not sure if it's that great of an idea for longer haul trips between distribution centers
Yields on silicon are great, but not perfect
