Lite Hash Rate and Resizable BARVideoCardz writes NVIDIA's partners have received a memo that GAxx2 GPUs will start shipping by the middle of May. This means new cards will likely hit the market sometime in June. Video cards with the new GAxx2 GPUs will not be differentiated from existing models.
The biggest difference is that GAxx2 GPU are so-called "Lite Hash Rate" chips, they will implement the newest version of NVIDIA's hash rate limiter. The goal here is still the same, to get more GeForce cards in the hands of gamers by making these GPUs less attractive to miners. VideoCardz speculates the GAxx2 GPUs will also support Resizable BAR out of the box, without the need for a vBIOS update.
With the ‘quiet launch’ of the RTX 30 LHR series, the supply of Ampere GPUs is expected to improve. NVIDIA has not yet provided an explanation of what exactly has been changed that would limit mining performance on the new chips. The previous attempt to introduce a software limiter with RTX 3060 has spectacularly failed after NVIDIA ‘accidentally released a driver without it. This SKU will also receive a new version with a reintroduced crypto limiter.GAxx2 GPUs will have a new PCIe Device ID so it will be able to recognize these models via software tools.
VideoCardz heard it's still unknown whether the GeForce RTX 3090 will get the hash rate limiter. The site heard mining isn't very profitable on this model due to its high retail price, so NVIDIA may choose not to restrict mining on this GPU.
