At yesterday’s CES event, Intel officially announced a new generation of 10nm processor Stiger Lake, using the new Willow Cove Core and Gen12 core, and for the first time integrated Thunderbolt 4 technology, to know the 10nm Ice in the early part of last year Lake was only the first to start with the Thunder 3.
CES Field Intel did not detail the specifications of the Thunder 4 technology, only that it is more than four times the speed of the USB standard – given that the latest USB standard USB 3.2 speed has reached 20Gbps, then 4 times the speed does not mean that the ThunderBolt 4 speed can reach 80 Gbps, is twice the Thunder Bolt 3?
Then it’s not that Intel’s vague language makes a lot ofmedia guess wrong, and then Intel also clarified that they now compare 4 times USB speed refers to USB 3.1, or more accurately, USB 3.2 Gen2, rate 10Gbps just.
As a result, Intel’s Thunderbolt 4 speed is actually 40Gbps, and like The Thunder 3, it doesn’t change.
In short, for the Thunder 4 so soon announced, including the TH website, includingmedia are skeptical, think it is only thunder 3 armor, Intel just changed the name.
In the end, of course, it will be up to Intel to clarify how much the Thunder 4 standard has changed, after all, there are other details beyond the speed that have not been announced.
As for why the name change, personal speculation in addition to marketing promotion convenience, Intel probably want to want the Thunder 4 and the future USB 4 standard unified, because the USB 4 standard attracted the Lightning 3 technology, the rate is also 40Gbps, and more general, also do not need additional licensing fees.
Finally had to slot USB again the official organization USB-IF, for so many years has not seen such a bottomless technical standards organization, from USB 3.1 has been repeatedly renamed, deliberately confusing the name so that consumers can not distinguish BETWEEN USB 3.1, USB 3.2, USB 3.2 Gen 2 or USB 3.2 Gen 2×2, is entirely taking care of the interests of manufacturers, otherwise I really can’t figure out why.
Perhaps it is more than slotting, in the USB4 standard, they finally converge some, the current USB4 standard has not changed the name of the signs, I hope there will be no such problems.
