Solo mining odds — AMD Ryzen 9 7900X3D on Xelis
13.30 KH/s · Xelishashv3 · network 49.88 MH/s. A AMD Ryzen 9 7900X3D solo mining Xelis (XEL) has about 1,448 blocks per year, i.e. an expected block roughly every 6.1 hours for the full 0.3100 XEL reward.
Can you solo mine Xelis with a AMD Ryzen 9 7900X3D?
Yes — a AMD Ryzen 9 7900X3D (13.30 KH/s) can solo mine Xelis (XEL) via a solo pool. At Xelis's 49.88 MH/s Xelishashv3 network that is about 1,448 blocks per year — expected one block roughly every 6.1 hours, for the full 0.3100 XEL block. BackPoW computes this from live network difficulty using a Poisson block-discovery model. Realistically this is genuinely worth a patient solo run.
Hardware Tier & Ecosystem Ranking on Xelis
The AMD Ryzen 9 7900X3D is categorized in the Mid-Range Workhorse Tier (Middle quartile hashrate offering solid pool mining throughput with moderate solo variance.). Among all 8 tracked models on Xelis, it ranks #1 in electrical efficiency (132.97 H/W) and #5 in raw hashrate (13.30 KH/s).
Electricity Operating Costs & Breakeven
Running a AMD Ryzen 9 7900X3D (100 W) pulls about 2.40 kWh per day (73.1 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.17 USD per day (5.04 USD/month or 60 USD/year). Statistically that year returns 1,447.94 blocks, worth about $117 — expected revenue covers the power bill about 1.9x over.
The operational breakeven threshold is 0.134 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +0.22 USD / day
- At 0.069 USD/kWh (Standard Industrial): +0.16 USD / day
- At 0.120 USD/kWh (Residential Grid): +0.03 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Xelis must trade at or above 0.1348 USD at standard industrial power (0.069 USD/kWh), or 0.2344 USD at residential power (0.120 USD/kWh).
Bankroll & Variance Risk Simulator
Solo mining block discovery follows a memoryless Poisson distribution. While the average wait is 6.1 hours, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~18.6 min (1-in-20 fastest discovery, power cost: ~0 USD)
- Median expectation (50% Odds): Block within ~4.2 hours (Nominal median, power cost: ~0 USD)
- Bad luck streak (5% Odds): Can stretch up to ~18.1 hours (1-in-20 extended dry spell, power cost: ~0 USD)
High Variance Alert: In a 1-in-20 severe drought (~18.1 hours), cumulative electricity burned (~0 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.

Current market price: $700. Mined against its most profitable coin instead of solo, it would pay itself back in about 4.7 years.
How other hardware compares on Xelis
Devices in the same hashrate class, solo mining Xelis at today's difficulty:
| Hardware | Hashrate | Expected block | Chance in 1 year |
|---|---|---|---|
| AMD Ryzen 9 7900X | 16.45 KH/s | 4.9 hours | 100.00% |
| GeForce RTX 4090 | 15.02 KH/s | 5.4 hours | 100.00% |
| GeForce RTX 3080 Ti | 13.01 KH/s | 6.2 hours | 100.00% |
| GeForce RTX 3080 12GB | 11.02 KH/s | 7.3 hours | 100.00% |
| GeForce RTX 3080 | 10.97 KH/s | 7.3 hours | 100.00% |
How the odds have moved
Xelis's network hashrate climbed 2% since 2026-08-09, from 48.72 MH/s to 49.88 MH/s — so the same rig is now 2% less likely to find a block.
How the odds are calculated
Solo mining is memoryless: every hash is an independent lottery ticket, so the wait for a block follows an exponential distribution rather than a fixed schedule. On average a block takes T = network_hashrate ÷ your_hashrate × block_time, and the probability of finding at least one within a window t is P = 1 − e^(−t/T). BackPoW uses this Poisson relation instead of a naive linear estimate. For this pair: daily chance 98.10%, yearly chance 100.00%.
