Compared with N5, the N3 process promises 10-15 percent higher performance at the same power usage, or 25-30 percent lower energy use at the same performance level. A lot of the initial 3nm capacity is going to Apple, which means other companies will need to find alternatives.
Given how companies like Apple are attempting to one-up their rivals by securing next-generation chip shipments, it is not surprising to hear from this latest report that TSMC’s 3nm orders are also completely booked. This means Apple again would have struck a deal with its supply chain partner, as a previous report claims that TSMC is racing to build 3nm chips for Apple’s iPhone 14 family in the second half of 2022.It's also claimed that Apple will use TSMC's 4nm node for some products.
