Almost certainly has to do with cost and PCI-E bandwidth. Mobile chips like this only have so much bandwidth, and USB3 requires more dedicated bandwidth than USB2, not to mention more complicated circuitry that drives up price. And when your expected use case is attaching keyboards and mice, which generally are USB2 only anyways, it reduces the cost and bandwidth needed to support that many ports.
- bredren 5y agoPresumably most people use usb for peripherals that don’t require usb3 spec. Webcams, input devices, etc.
- sudosysgen 5y agoIt's not really a mobile chip, it's a full laptop-grade Zen 2 processor.
- jreese 5y agoPCIE lanes are still a function of both the CPU and the motherboard chipset. It's cheaper to build a board with fewer PCIE lanes, and cheaper to have fewer components that need said PCIE lanes.
- caslon 5y ago"laptop-grade" is mobile, in CPU terms. That's why Intel marks their laptop chips with an "M" at the end.
- sudosysgen 5y agoYes and no. There are desktop computers with laptop chips and laptop chips are much closer to desktop than to a phone for example
- half-kh-hacker 5y agoIn this context, 'mobile' does not mean 'phone', it means 'portable'.
- sudosysgen 5y agoSure, and "portable" is a useless class of chips. It's too large to be useful.
- kbumsik 5y ago> full laptop-grade Zen 2 processor. That's exactly what we call a "Mobile" chip in the x86 CPU market. The mobile phone grade chipsets you are probably thinking is probably called "Embedded" chip in the x86 market. ("Embedded" chips is wider than a mobile phone though)
