NVIDIA GeForce RTX 30 LHR graphics cards tested in Ethereum Mining with updated NBMiner

A few hours ago, we reported how the latest NBMiner update partially unlocked the mining hash rate on NVIDIA’s GeForce RTX 30 LHR series graphics cards. The first mining figures are available and show that these cards actually provide up to 70% of their mining capacity within the Etherum (ethash) mining algorithm.

The three main graphics cards of the NVIDIA GeForce RTX 30 LHR series shown in the tests are all “Ti” variants, the RTX 3080 Ti, RTX 3070 Ti and RTX 3060 Ti. As expected, the latest updates to NBMiner partially unlocked (up to 70%) the mining performance of these cards and while still not at 100%, they are better than the hash rate of 50 % that miners were getting before this update. NBMiner also expects to unlock higher performance in future updates, but that remains to be seen.

When it comes to performance, the NVIDIA GeForce RTX 3080 Ti delivers around 65 MH / s. The standard RTX 3080 delivered around 90 MH / s (without settings). The RTX 3080 Ti comes with a larger memory bus and higher bandwidth, so here we take a look at the 60-65% performance of the RTX 3080. The NVIDIA RTX 3070 Ti does slightly better and delivers around 50MH / s while the RTX 3070 delivers around 60 MH / s. Switching to the RTX 3060 Ti we get around 40 MH / s which is 20 MH / s less than the non-LHR variant and 10 MH / s less than the RTX 3060 (Non-Ti) which is rated at 50 MH / s. Here are the numbers in the list view:

  • NVIDIA RTX 3080 Ti (LHR) – ~ 65 MH / s (RTX 3080 non LHR – ~ 90 MH / s)
  • NVIDIA RTX 3070 Ti (LHR) – ~ 50 MH / s (RTX 3070 non LHR – ~ 60 MH / s)
  • NVIDIA RTX 3060 Ti (LHR) – ~ 40 MH / s (RTX 3060 non LHR – ~ 50 MH / s)

Currently, LHR graphics cards offer half of the total hash rate they are intended for, but with the new update you can set that value to 68% (as the developer recommends). This only works in Ethereum (ethash’s algorithm), but there is now a chance that other mining algorithms will adopt it as well.

This new LHR mode mining update for the NVIDIA GeForce RTX 30 series is compatible with Linux and Windows systems on existing NVIDIA drivers. Based on the changelog, it looks like the developers are also working to make this unlock work on other mining algorithms. While this is good news for minors, it’s not really good news for the gaming segment which is just starting to recover in terms of overall supply, availability and pricing. This update has the potential to lead to an increase in demand for LHR graphics cards, which could lead to an even more serious shortage of gaming GPUs.
