This is a five-foot-long PCIe x4 cable - GPU extensions are four inches. It can feed two 4K displays at 60Hz. It can transfer data faster than an NVMe drive can store it. The fact that this is even physically possible is astounding.
It is. But it's also possible with the $40 and $60 cables I mentioned. They're all active Thunderbolt 4 40Gb/s cables that measure about 2 meters long.
