how last a new chain? gx vs x01

[chamaruco]

the gx was the stock one and i've replaced it (0.50 on my gauge) after 1000kms.
now the x01 is at the same point after less then 800kms...
a counterfeit item? or they are the same...in terms of consumption? or my expectation were too hight?

The latter.
There's not a massive difference in the wear rates of SRAM chains from the cheapest to most expensive models.
It also stands to reason that a new chain fitted to a drivetrain with a part worn cassette and chainring would wear faster than a new chain on a new cassette and new chainring.
The conditions it was ridden in how smoothly the rider changes gears and how it was looked after (cleaned/lubed etc.) all play a part in how quickly a chain wears
If you're going to swap chains out regularly in an attempt to eek longer life out of your cassette and chainring it doesn't really make a whole lot of sense to do it with expensive chains.
X01 is also a hollow pin chain which isn't really what you'd want to be using on an Emtb - It is a whole 5g lighter for it though

I think Gary answered that one precisely.

They are close in terms of consumption. You mostly pay for weight savings. But you do not need to save weight on emtb. At bicycles speed unsprung mass has no any influence, and on motor assisted bicycle there is no reason to save a few hundred grams. So it is smarter to use the cheapest speed system for emtb. Emtb just utilize regular bicycle speed systems due to limited emtb market, but only on regular bicycle weight savings make sense due to limited human power.

Hmmm. I’m not an expert but this seems to indicate a significant difference.

it seems to me your problem is that by the time you replaced the GX it had already worn the cassette and that then wore out the new chain.

A seller could be a reference? I’m understanding that I’m a marketing victim in this case. Even if the cassette was worn at time of the first replacement even more so I was wrong buying an expensive chain hoping something better then the previous. Anyway I thing Gary is right. The comparison is useless comparing two periods of the same cassette.
Anyway just to mix us up I found the links that I removed to shorten the chain(first pic) and the actual situation (pic below)
