Antminer S21+ 216 TH/s vs S21 Pro 234 TH/s vs Avalon A15 Pro 221 TH/s
Comparing three of the most competitive professional Bitcoin miners available from EU stock: the Bitmain Antminer S21+ (216 TH/s), Antminer S21 Pro (234 TH/s) and Canaan Avalon A15 Pro (221 TH/s). All three are SHA-256 ASIC miners targeting serious Bitcoin mining operations with different price-to-performance trade-offs.
Bitmain Antminer S21+ (216 TH/s)
The Antminer S21+ delivers 216 TH/s at approximately 3,570W, giving an efficiency of around 16.5 J/TH. It sits in the mid-range of this comparison — more hashrate than many previous-generation miners and a lower price point than the S21 Pro. For farms looking to scale at a reasonable cost per terahash, the S21+ offers a strong return on investment.
Bitmain Antminer S21 Pro (234 TH/s)
The Antminer S21 Pro is Bitmain's most efficient air-cooled SHA-256 miner in this lineup, delivering 234 TH/s at ~3,510W — just 15 J/TH. That efficiency advantage adds up significantly at scale: over a 3-year lifespan, the S21 Pro saves thousands of euros in electricity compared to less efficient models. At €5,549.87 it commands a premium, but the total cost of ownership often justifies it for serious miners.
Canaan Avalon A15 Pro (221 TH/s)
The Canaan Avalon A15 Pro delivers 221 TH/s at 3,662W (16.6 J/TH) and is the most affordable option in this comparison at €3,399.87 — over €1,100 cheaper than the S21 Pro. Canaan has a strong track record for hardware reliability, and the A15 Pro ships from EU stock with no import duties for European buyers. It is the best value-per-terahash option for budget-conscious miners.
Efficiency Breakdown
Efficiency is everything in Bitcoin mining — it determines your operating cost and long-term profitability. The S21 Pro wins at 15 J/TH, followed closely by the S21+ at 16.5 J/TH and the A15 Pro at 16.6 J/TH. The difference between S21 Pro and A15 Pro is ~1.6 J/TH — on a 100-unit farm running 24/7, that translates to roughly €4,000/year in extra electricity at €0.07/kWh.
Which Should You Choose?
Choose the Antminer S21 Pro if electricity is your biggest operating cost and you plan to run miners long-term — the efficiency savings pay back the premium. Choose the Avalon A15 Pro if you want to maximise hashrate per euro invested upfront and your electricity rate is low. Choose the Antminer S21+ for a solid middle ground — strong performance without the S21 Pro price tag. All three are available from EU stock at Mineshop.eu with fast European shipping and no customs fees.
