Are all new nVidia cards gimped by LHR now? Even the 3080 and 3060Ti's?
The new batch yes it is.It is very difficult to find a new RTX 3060 ti non LHR while for RTX 3080 you maybe a bit more lucky and manage to find one but for the 3060 ti is impossible to buy it new non-LHR now.I would still buy it used though as it does pretty well at 58-60 Mhsh for 120 watt power consumption.
The LHR are easy to spot though,each brand has its own code,for example Gigabyte rev 1.0 is non-LHR card while rev 2.0 is a LHR card.
