Not correct, The 3080Ti will not be LHR because LHR implies there was a model without LHR.The 3080Ti and 3070Ti came with the hash rate already cut therefore they do not need to differentiate between it and SKUs which came earlier without a LHR limit. The other models, so 3080, 3070 and 3060Ti have chips produced prior to the introduction of LHR, so there your will see differentiation. So no they are not wrong, Nvidia or AIBs for that matter do not need to spit out the 3080Ti is LHR as that is what it has always been in publicly.
The article does make a leap in logic on some parts, but does not negate the part where assuming they are not outright lying about Nvidia telling them: "Founders Edition is a limited production graphics card sold at MSRP," Nvidia told us this afternoon, "and at this point we don’t have plans to make versions with LHR." Now PC world may have misinterpreted limited production to mean EOL which is a leap, but I can believe the FE models which do not have LHR from the onset applied (so 3090, 3080, 3070 and 3060Ti) may see the same rates. The 3080Ti and 3070Ti in FE models will see there hash rate cut. I suppose we will see when people on more recently purchased 3080's, 3070s and 3060Tis.
