At least according to Corsair, there are no changes to the cable, only the PSU/GPU-side connectors:

> Cable: 12V-2x6 = 12VHPWR No difference!

> So what does this mean if you’ve already got hardware for 12VHPWR? Fortunately, existing 12VHPWR cables and adapters will work with the new 12V-2x6 connector as the new changes are only related to the GPU and some PSUs (Our new RMx PSUs for example). The cables you've got already will work fine, so don't worry.

Connectors are where the issue is and there is a difference even if they fit in the same plugs and power can still go through them.

From your link

> Compared to the original 12VHPWR connector, the new 12V-2x6 connector has shorter sensing pins (1.5mm) while the conductor terminals are 0.25mm longer

AIUI, the connector _on the GPU/PSU_ is slightly different, but the connector on the cable is the same:

> As with any new standard, things are likely to evolve quickly and we’re now seeing the introduction of a new connector on the GPU and the PSU side of things. To be clear, this is not a new cable, it is an updated change to the pins in the socket, which is referred to as 12V-2x6.

Corsair's messaging on Reddit[1] emphasises this:

> Cable is the same. a 12VHPWR cable is a 12V-2x6 cable. it is ONLY the plugs on the graphics card / power supply that have changed.

> The cable is the same. 12VHPWR = 12V-2x6. You will get the exact same cable if you upgrade to a new PSU.

> As mentioned in image one, the cable is the same. Only the plug on the graphics card / PSU changed from 12VHPWR to 12V-2x6.

That's inconsistent messaging from Corsair, then. Parent comment quotes the times they're like "ehh, they're same thing, don't worry about it" and then they go on to say "well TECHNICALLY there's a teeensy difference in conductor sizes"???

Either they are confident that the 0.25mm terminal difference is within tolerance enough that they consider 12VHPWR to be functionally equivalent to 12V-2x6, or they're getting themselves confused let alone the target audience of their article.
