Is the RX 6800 good for Monero mining?
No—the Radeon RX 6800 is generally not a good choice for mining Monero directly. It is a powerful graphics card, but Monero’s mining system favors your computer’s processor, so using the RX 6800 usually means poor returns for the electricity it uses.
Why the RX 6800 is a poor match
Monero uses RandomX, the set of calculations miners perform to help secure the network. It replaced the earlier CryptoNight mining system in November 2019 and was designed to favor CPUs, the main processors in PCs and servers.
Your RX 6800 is a GPU, a graphics processor built to handle many similar calculations at once. That makes it excellent for some workloads, but RandomX relies on a mix of instructions and memory access patterns that suit CPUs better.
The RX 6800’s 16 GB of video memory does not change that. RandomX’s fast mode uses a dataset of about 2,080 MB, but fitting that data into memory is only one requirement. The way the processor works with that data matters much more.
Be careful with old mining guides. Good results for a Radeon card on CryptoNight do not tell you how it performs on Monero’s current algorithm.
If you already own an RX 6800
You do not need to replace your graphics card to try Monero mining. Instead, look at the CPU already installed in your PC.
For RandomX, useful CPU features include:
- Enough L3 cache: This is a small, fast store of data inside the processor. Budget roughly 2 MB per mining thread, meaning each separate stream of mining work.
- Efficient power use: More mining work is not automatically better if electricity costs rise faster.
- Suitable memory and cooling: Memory settings and sustained temperatures can affect performance.
You can leave the RX 6800 mostly idle while your CPU mines. However, measure electricity use for the whole PC, not just the CPU. The graphics card, fans, memory, and other parts still contribute to your bill.
If you are buying hardware specifically for Monero, spending that budget on an RX 6800 is usually the wrong move.
What about mining through your browser?
Opening a mining page does not automatically put your RX 6800 to work. Browser mining commonly uses the CPU through code running inside the browser. GPU use requires explicit support; you should not assume a website has it.
Browser limits can also make mining less efficient than dedicated mining software. Before starting, check what the service actually mines, which hardware it uses, its fees, and its withdrawal rules.
A service that pays you in XMR is not necessarily mining Monero directly. It may mine another coin and exchange the proceeds for Monero. That is a different setup, and its economics depend on that other coin, conversion costs, and service fees.
The bottom line
Keep your RX 6800 for gaming or other graphics workloads rather than buying or running it specifically for Monero mining. If you want to experiment, assess your existing CPU first.
Check a live profitability calculator using a measured mining speed and your electricity rate. Treat promised fixed daily earnings with suspicion, and never pay an “unlock fee” to release supposed mining profits. For this card, direct Monero mining is generally a poor hardware match—not an easy source of income.
