After being burned by two fake 'Thunderbolt' cables from marketplace sellers, I paid a bit more for the Intel-certified one. Zero issues — my external SSD hits full 40Gb/s speeds and my monitor runs 8K without a flicker. The white braided finish matches my setup too. You get what you pay for.
Connected my laptop to a Thunderbolt dock with this and everything just works — dual 4K displays, gigabit ethernet, charging all at once. 0.8m is the perfect length for a desk setup. Can't ask for more from a cable.
Performance is flawless — full speed data, 8K output, 100W charging, all confirmed. My only note is that 0.8m is short for some setups; measure your desk before buying. For a dock sitting next to your laptop, it's perfect.
Charges and displays at full speed. Solid build.
No performance complaints — it does 40Gb/s and 8K exactly as claimed. It's just hard to get excited about spending this much on a cable, even on sale. The build quality is nice and the certification gives peace of mind, but I'm knocking stars for value.
My MacBook drives two monitors, a dock, and charges through this single 0.8m cable and it's been rock solid for months. The white color is a nice change from the usual black spaghetti. Razer build quality is evident — the strain relief looks like it'll outlast my laptop.
Many 'Thunderbolt' cables max out at 4K60 despite the marketing. This one officially supports 8K and my monitor's OSD confirms the full bandwidth. Data transfer to my NAS is also noticeably faster than with my old cable. Docked a star only because the cable is a bit stiff out of the box.
Speeds test fine when connected, but the USB-C plug sits loose in both my laptop and dock. If I bump the desk, the display cuts out. A cable this expensive shouldn't have a loose connector. Maybe mine is defective, but I can't trust it for a monitor connection.
