Intel Unveils the Thunderbolt 4 Spec, Debuting in PCs in the Fall
Intel unveiled Thunderbolt 4 on Wednesday, the next iteration of the I/O specification that provides a high-speed peripheral bus to docks, displays, external storage and eGPUs for PCs. Rather than increase the available bandwidth, however, Thunderbolt 4 provides more clarity and helps create new categories of products. From a report: Thunderbolt 4 will debut later this year as part of Intel's "Tiger Lake" CPU platform, as Intel originally announced during CES in January. We now know it will support 40Gbps throughput, but with tighter minimum specs. Thunderbolt 4 will guarantee that a pair of 4K displays will work with a Thunderbolt dock, and require Thunderbolt 4-equipped PCs to charge on at least one Thunderbolt port. Thunderbolt PCs will be able to connect to either "compact" or "full" docks with up to four Thunderbolt ports. Longer Thunderbolt cables will be possible, too. One thing that doesn't seem to be changing is Thunderbolt's exclusivity. Intel developed Thunderbolt, and perhaps not coincidentally, OEM systems based on rival AMD's CPUs have never had this technology. While AMD has officially dismissed the need for Thunderbolt, with generation 4 Intel appears to have made it even harder for AMD to get it, even if it wanted to. Intel's still pitching Thunderbolt as a single standard to rule them all, but the reality up to now has been complicated. You still have to squint hard at that USB-C-shaped port to determine which of the multitude of USB specifications it meets, including whether it's a USB4 connection that happens to support Thunderbolt. To muddy things further, Thunderbolt also encompasses PCIe, DisplayPort, and USB Power Delivery standards.Read more of this story at Slashdot.
