Lack of USB controllers can affect the availability of a laptop with Intel Tiger Lake processors

There may be a shortage of new laptops with Intel Tiger Lake processors. The new Thunderbolt 4 standard requires an external power delivery chip. But they are running out.

Intel has outpaced competition with Tiger Lake chips in notebooks, and in many cases has outperformed it. This is a key market for the company, as desktop chips have not been received with great enthusiasm. Unfortunately, even with laptops, everything gets complicated. Availability is compromised due to an external power delivery chip that must be added to the motherboard.

According to a source at, the availability of these chips from Texas Instruments is very poor. Manufacturers are thus moving from the 994AD chip to others labeled 993AC and 994AC. For those, Intel recommends mentioning the trouble-free function only when connected via the Thunderbolt protocol. Within USB 4, these chips are not always compatible. This pair of chips cannot regulate the power supply when using the USB 4 standard.

Manufacturers can choose and use alternative chips, or wait for the original fully compatible. In the latter case, however, production may slow down due to a lack of controllers. For now it is selection of laptops with Tiger Lake chips sufficient so far.
