The RTX 3080 is widely praised as one of the best gaming GPU’s to the date. Not only it’s more powerful than the RTX 2080, it’s also cheaper, making it undeniable a better bang for the buck.
Since the card is only a few months old, little is known about its mining performance. Luckily for me, one of my friends happened to assemble a monster gaming rig with an Gigabyte RTX™ 3080 VISION OC 10G, and a new gen Ryzen 5 5600x. That beast of a PC can run Call of Duty Warzone at 240 fps average.
The man was nice enough to let me test his GPU on several mining algos.
Note: I will be getting my hands on the RTX 3090 soon to benchmark it and test it in my rigs.
As you will be able to see below, my first tests with the 3080 did not give the most breathtaking results. There are two reasons for that:
There is still no software support that would let us enjoy the full potential of the 3080 for mining. We need both better mining software and better drivers. This is pretty common for cards that are new to the mining community. Note: I was not able to test it with Bminer due to a library error.
The Gigabyte version apparently has issues with memory cooling, which causes hashrate drops over time. This issue is present on the Eagle OC, Vision OC, and the Gaming OC cards.
The Asus RTX™ 3080 10G, on the other hand, is reported to hash up to 97 Mh/s, though it’s not a card I had the chance to test yet. I have also not experienced any cooling issues with the 2080 and 2080Ti Gigabyte cards, so that’s a new. I will be looking further into this issue these days, and I will keep you updated.
The power consumption on the GeForce RTX™ 3080 Vision OC is quite high, with up to 350W on standard clocks, and around 250W at 70% power limit. I obviously run it on the lower power consumption settings, which give me 85 Mh/s on average for Ethash. Here’s a full list of algos and their respective hashrates:
RTX 3080 vs. RTX 2080 vs. GTX 1080Ti Mining Hashrate
Gigabyte RTX 3080
0.37 /mh/s per watt
0.077 Mh/s per invested dollar*
Gigabyte RTX 2080
0.391 mh/s per watt
0.034 Mh/s per invested dollar*
Gigabyte GTX 1080 Ti
40 Mh/s (pill)
0.242 mh/s per watt
0.04 Mh/s per invested dollar*
(*) Values based on the best prices I was able to find at the moment. The GPU market is known for being volatile, so these numbers should be taken as reference only.
So far, the Gigabyte 3080 is not offering the best power efficiency even with its power consumption reduced by 30%. Another thing to keep in mind is that powerful PSUs cost a lot, at the point it might be more profitable to assemble a rig that produces less but also consumes less, and thus doesn’t require a huge PSU to operate.
Now, if power efficiency isn’t as much of a concern for you, then the 3080 does offer way better hashrate per dollar invested.
As for now, it’s hard to have a conclusive opinion on the RTX 3080. It’s a new card, so it’s very probable that we haven’t unlocked its full mining potential yet. It does look like a better investment than the previous models but only because of how overpriced 1080’s and 2080’s currently are.
I will keep you updated on this, and I am also getting the RTX 3090 soon to benchmark it. Have a good one!
