NVIDIA's soon-to-be-released GeForce RTX 3080 Ti and the entire existing GeForce RTX 30 lineup will soon be getting revised Ampere GPUs to tackle cryptocurrency mining. The new GPUs will be featured on all upcoming graphics cards under the GeForce RTX 30 family while the ones that are already released and sold to users would remain unaffected.
NVIDIA's Entire GeForce RTX 30 Lineup Including The GeForce RTX 3080 Ti To Get Revised Ampere GPUs To Tackle Cryptocurrency Mining
While we had already got a hint of this happening a few weeks back, Igor's Lab has dug up some more information with the help of their sources at graphics card manufacturers. According to the source, the initial batch of the GeForce RTX 3080 Ti graphics card based on the GA102-225-A1 GPU core was still not fully protected against cryptocurrency mining. The GPU in its current QS state is still able to produce full hash rate performance in mining algorithms with the existing 470.05 BETA driver.

To tackle this, NVIDIA has now submitted a newer Ampere GPU which should be known as GA102-22*-A1, & will be mass-produced for the GeForce RTX 3080 Ti graphics card instead of the GA102-225-A1 SKU. The new GPU is already in mass production and won't work with any existing drivers. The GeForce RTX 3080 Ti isn't the only GPU that will be getting a revised Ampere SKUs, in fact, the entire lineup will be getting newer chips as listed below (Rumor):
NVIDIA GeForce RTX 3090 - GA102-300-A1 -> GA102-302-A1
NVIDIA GeForce RTX 3080 - GA102-200-A1 -> GA102-202-A1
NVIDIA GeForce RTX 3070 - GA104-300-A1 -> GA104-302-A1
NVIDIA GeForce RTX 3060 Ti - GA104-200-A1 -> GA104-202-A1
NVIDIA GeForce RTX 3060 - GA106-300-A1 -> GA106-302-A1
The source reports that it is possible to flash the old GPU firmware on the new GeForce RTX 3080 Ti graphics card but that doesn't come without its own set of issues. NVIDIA has devised a way that if users flash the GeForce RTX 3080 Ti graphics card with the older BIOS firmware, that would result in a black screen and vice versa.
The reason for this is because the new Ampere GPUs come with a different hardware ID. This means that there's another parameter aside from the GPU-driver hand-shake that is preventing the BIOS firmware upgrade from working on the newer cards & that may totally limit full-hash rate performance for cryptocurrency mining algorithms. This approach won't affect the drivers since the device ID remains the same and NVIDIA won't have to prepare a new set of drivers for its new hash rate restricted Ampere GeForce RTX 30 lineup but it looks like that this solution will be somewhat complicated for miners to bypass.

NVIDIA's GeForce RTX 3080 Ti 12 GB FE (Founders Edition) graphics card is expected to feature the PG132-SKU18 PCB design and the GA102-225-KD-A1 graphics core. The GA102-225 GPU has also changed since the last time we saw them and will now feature 10240 CUDA cores within a total of 80 SM units. Since the main core configuration is entirely brand new, the previously leaked clocks & TMU/ROP counts should now be dismissed.
