There are actually a few articles over the past week where it's revealed that Jensen is unhappy with Samsung performance both on memory front and foundry as well, and in a pretty colorful language at that.
It a simple business. What was mass produced with Intel 4 so far? Mobile 14th gen Intel CPUs and that's it.
Meanwhile TSMCs comparable N4 was used to produce all the Series 40 GPUs, all Apple's Bionic 16 from 2 years ago (so all iPhones, iPads and so on) AND all the Snapdragon 8+ Gen1, so practically a good chunk of all smartphone SoCs in existence.
And it's not even the highest end commercially available process for TSMC, while Intel 4 is the best they got that even seen the light of day in some sort of production.
People think it's just some feels or favorites here. No, it's a hard cold reality of TSMC having commercial availability AND insane track record of delivering as shown above.
