Laptop Motherboard to support USB3
Hello group
Is there any idea when will the laptop manufacturers implement the USB3 in their motherboard? I have found some manufacturer are starting to do it such as Asus but its not yet widespread. Would the USB3 support be mandatory for all motherboards including netbooks , smartphones etc... Does it begin this year or later? TIA |

Would the USB3 support be mandatory for all motherboards including netbooks , smartphones etc... Does it begin this year or later? TIA Support right now, is provided via a separate NEC USB3 ship. (There is a picture of the chip here.) The NEC chip is a USB3 controller, requiring a PCI Express x1 revision 2 lane for its data connection to the rest of the computer. There is a picture here. http://www.sweclockers.com/imagebank...ull&k=ecfbcbf1 And this explains, what is happening to built-in chip support. At least Intel, is slowing the launch of USB3. And they could be doing it, to coincide with some other technology like "Light Peak". You never know, with Intel, what their reasoning might be. http://www.dailytech.com/Intel+Delay...ticle16588.htm http://en.wikipedia.org/wiki/Light_Peak ATI/AMD would be another major source of chipset technology, and perhaps their delivery schedule is different. On their latest chipsets, I can see SATA 6GB/sec technology, but no USB3 mentioned. http://www.amd.com/us/products/deskt...omparison.aspx If a laptop maker wants it *today*, they can have it. All they need to do, is solder the NEC USB3 chip onto the motherboard. And then you'd have it. I don't know how hard the NEC chip would be on the battery life. The cost increment of using that, isn't too big, but every penny counts to the manufacturer. They would not include something like that, unless the margin on the computer was large. Maybe an expensive, heavy unit, a gaming box perhaps, would be a good candidate for it. It'll only show up on the cheapest laptops/notebooks, when the feature is integrated into the chipset. Because, they have to pay the price for the chipset, and then that flavor of interface is "free". Paul |

Its reputed to contain the USB3 slot in combination with the USB2..? , Meaning that they are still using the USB3 PCI card type for this..? |

Its reputed to contain the USB3 slot in combination with the USB2..? , Meaning that they are still using the USB3 PCI card type for this..? The NEC chip handles two ports. If you had a computer with six ports, then chances are, they would not use USB3 connectors on all of them. If they're using that chip, the chip is expensive enough, they wouldn't use three of them in a design. Perhaps instead, four USB2 connectors and two USB3 connectors would be on the computer. A person with a desktop computer, is perfectly welcome to plug in three of those add-in cards if they want, if they want 6 connectors at USB3 rates. In the near term, a more likely scenario, might be a USB3 powered hub of some sort, used to increase the number of connectors. At least, until the chipset makers get their act together. I don't know and haven't checked, to see if any USB3 hubs have been created. USB is supposed to be backward compatible. The USB3 connector contains two sections, a legacy section for connecting the older cables. And a set of pins for the higher speed USB3 signals. They had to do that, to improve the signal quality enough for the 5 gigabit/sec signals. There are some nice pictures here, of USB3 connectors and other details. http://www.usb3.com/ Paul |

Hmm that make sense......so one USB3 plus 2USB2 slot will be the expected normal configuration of the upcoming laptop motherboard supposing it has three USB slots....

I don't know and haven't checked, to see if any USB3 hubs have been created. AFAIK its known that the latest motherboard for desktops are already designed to accessible to USB3, I was thinking that if that was the case then for the desktop it can have 100% straight USB3 slot is supposed to be backward compatible with USB2 connected devices.. There are some nice pictures here, of USB3 connectors and other details. http://www.usb3.com/ * * Paul Thanks for that great info Paul! Regards Roy |
