Quick Answer: Which ASIC Is Best for Bitcoin Cash Mining?

Bitcoin Cash (BCH) uses the SHA-256 proof-of-work algorithm, the same algorithm used by Bitcoin. This means BCH mining does not require a BCH-exclusive ASIC; a compatible SHA-256 miner can be pointed at a BCH stratum endpoint.

Among the five models compared below, the Antminer S21 XP+ Hyd. is a candidate for miners with suitable hydro-cooling infrastructure, with a rated efficiency of 11 J/TH and a spot listing at the time of checking. For air-cooled operations, the WhatsMiner M70S offers lower rated electricity use per unit of hashrate than the Avalon A15Pro+. The Avalon A16XP has a lower J/TH rating than both, but its current delivery batch needs confirmation. These are conditional comparisons, not a market-wide ranking of the best ASICs.

Selecting an ASIC for BCH mining is therefore less about finding a single “best” model and more about matching rated efficiency and power requirements to the infrastructure, electricity cost, cooling capacity, and purchase budget available at the mining site.

Bitcoin Cash Mining Does Not Require BCH-Specific Hardware

BCH and BTC are separate blockchain networks with independent difficulty adjustments and block histories, but both rely on SHA-256 hashing for proof-of-work. Consequently, the same ASIC chip design used for Bitcoin mining is capable of producing valid BCH shares and blocks. In a pool setup, the pool endpoint and mining settings determine which network the miner works on.

This distinction matters for equipment selection. There is no separate hardware category of “BCH miner” distinct from a general SHA-256 ASIC. A miner evaluating hardware for BCH should apply the same technical criteria used for Bitcoin ASIC selection: rated hashrate, rated power draw, energy efficiency in J/TH, cooling method, and manufacturer support, then confirm compatibility with the intended BCH pool. ViaBTC, for example, supports BCH mining with PPS+ and PPLNS payment methods. ViaBTC Mining Pools Information

Comparing Current SHA-256 ASIC Options

The table below summarizes manufacturer specifications for five SHA-256 ASICs relevant to BCH mining. Specifications and storefront information were checked on September 28, 2026. This is a selected comparison, not an exhaustive market survey. All performance figures are manufacturer-rated values, not independently measured field results, and actual performance can vary with operating conditions and configuration.

Storefront labels describe the listings checked, not guaranteed delivery to a particular site. Confirm the exact configuration, warehouse, available quantity, and shipping schedule before purchase.

Antminer S21 XP+ Hyd. is a hydro-cooled option for operations with a compatible cooling loop and electrical supply. Its 480 TH/s hashrate and 11 J/TH rating provide a useful reference for this comparison, but these figures alone do not establish the lowest total ownership cost.

Antminer S23 XP Hyd. has the lowest rated J/TH in this table, at 8.9 J/TH. Its futures listing means the quoted delivery batch should be checked before including it in a near-term deployment plan. A lower rated electricity requirement does not, by itself, establish whether waiting for the unit is worthwhile.

WhatsMiner M70S and Avalon A15Pro+ are air-cooled options for operations without a hydro loop. At the listed configurations, the M70S has both higher hashrate and lower power draw than the A15Pro+, making it the stronger of these two on rated electricity efficiency. Purchase price, delivery, and support may still change the overall decision. Air cooling avoids the coolant loop and water-treatment requirements of hydro cooling, but electrical requirements remain model-specific.

Avalon A16XP provides a more efficient air-cooled comparison point at 12.8 J/TH. Canaan's catalog still labels it as futures, while its product page lists shipping from Q2 2026. That date has already passed as of this comparison, so the label alone does not establish whether a suitable batch is available now. Confirm current stock and dispatch timing directly before including or excluding it from a deployment plan.

As a further reference point, the earlier Antminer S21 XP Hyd. is rated at 473 TH/s, 5,676 W, and 12 J/TH under a 35°C inlet-water condition, with Bitmain noting that actual hashrate may vary by ±3% and wall power and efficiency by ±5%. This unit also requires three-phase 380–415 V AC input and a coolant flow of 8–10 L/min within specified chemistry limits. These requirements illustrate why hydro-cooled hardware is not a straightforward drop-in replacement for an air-cooled setup; check the exact model's requirements before deployment. Bitmain Support

How to Choose the Right ASIC for BCH Mining

Selecting hardware for BCH mining involves several factors beyond the headline hashrate figure.

Algorithm compatibility. Confirm that the ASIC supports SHA-256 mining and works with the intended BCH pool.

Rated efficiency (J/TH). Lower J/TH means less rated energy consumption per terahash, which generally reduces electricity cost per unit of hashrate, all else equal.

Power draw and electrical supply. Verify that the site's supply, cabling, and circuits meet the selected miner's requirements. Hydro-cooled models may require three-phase power at specific voltage ranges, while air-cooled units also need appropriate electrical infrastructure. For example, the M70S product page specifies a 220–240 V AC power supply. WhatsMiner M70S specifications

Cooling method. Air-cooled units avoid the need for a coolant loop but still require adequate airflow and heat removal. Hydro-cooled units require pumps, coolant management, and compatible heat-rejection equipment. Compare the exact models and the facility power they need rather than assuming that cooling method alone determines efficiency.

Purchase cost, delivery timing, and support. Compare purchase price and facility costs alongside the manufacturer's quoted delivery batch. A spot or futures label is useful context, but it does not replace an order-specific shipping commitment. Warranty terms and access to repair parts also affect the total cost of operating a unit over its service life.

Noise and heat management. Air-cooled ASICs generate substantial fan noise and exhaust heat, which affects siting decisions for home or small-scale operations.

Pool compatibility and payout method. Confirm that the intended pool supports BCH mining and review the available payout methods, since this affects how mining rewards are calculated and distributed.

For an existing hydro-equipped site, compare the S21 XP+ Hyd.'s quoted total deployment cost with the S23 XP Hyd.'s efficiency and delivery timing. For an air-cooled site, compare the M70S and A15Pro+ using actual purchase quotes, and include the A16XP if its confirmed dispatch date fits the project. This keeps the shortlist tied to equipment the site can power, cool, and receive on time.

Estimating BCH Mining Operating Costs

Electricity is typically the largest recurring cost in ASIC mining, and it can be estimated using the ASIC's rated power draw:

Daily electricity cost = (Miner power in watts ÷ 1,000) × Operating hours per day × Electricity price per kWh

For example, an Antminer S21 XP+ Hyd. rated at 5,280 W, running at that power for 24 hours, consumes:

5.28 kW × 24 hours = 126.72 kWh per day

This figure reflects the ASIC's own rated electricity draw. It does not include the additional load from dry coolers, circulation pumps, ventilation fans, transformers, or other facility-level equipment that a hydro or large air-cooled deployment may require. When comparing total operating cost between hydro and air-cooled setups, these facility-level loads should be added separately rather than assumed to be zero.

BCH-denominated mining earnings depend on network difficulty, accepted mining work, uptime, transaction fees, the pool's fee structure, and the payout method used. BCH price determines the fiat value of those earnings; a price change alone does not change the number of BCH earned when the other mining conditions remain unchanged. Net profitability also depends on electricity and other operating costs.

A profitability estimate reflects the conditions used at the time of calculation. It is not a guaranteed future result, since BCH price, network difficulty, and operating conditions can change.

Connecting a SHA-256 ASIC to a BCH Mining Pool

Once hardware is selected, mining BCH requires configuring the ASIC for a pool that supports BCH. ViaBTC's BCH mining documentation lists stratum+tcp://bch.viabtc.io:3333, with port 443 as another option, and recommends configuring multiple ports for failover. The guide also explains worker naming and miner configuration. ViaBTC BCH Mining

ViaBTC's Smart Mining currently offers One-click Switch for BTC and BCH. After configuring a Smart Mining endpoint such as stratum+tcp://bitcoin.viabtc.io:3333, miners can select the coin through the pool's mining settings. This is a miner-selected switching function, not an automatic profitability-based switching service. Smart Mining · One-click Switch setup

For BCH, ViaBTC supports PPS+ and PPLNS. PPS+ pays the subsidy component based on valid shares, while distributing the pool's actual transaction-fee income through PPLNS. Review the method and applicable fees when estimating earnings. ViaBTC payment methods

Conclusion

There is no single ASIC that is objectively best for every BCH mining operation. Among the models compared here, the S21 XP+ Hyd. is an option for an existing hydro-equipped site, while the S23 XP Hyd. offers lower rated J/TH subject to its delivery schedule. For air-cooled operations, the M70S has better rated electricity efficiency than the A15Pro+, and the A16XP offers a further efficiency comparison if its availability meets the project timeline.

In every case, the practical value of an ASIC for BCH mining depends on rated efficiency, purchase and facility costs, delivery, uptime, and pool terms. Match the hardware to the site's constraints before deciding which specification advantage is worth paying for.

FAQ

Does Bitcoin Cash require a different ASIC than Bitcoin?

No. Both BCH and BTC use SHA-256, so a compatible ASIC can mine either network through the appropriate pool endpoint and mining settings.

Is the Antminer S23 XP Hyd. available for purchase now?

As of September 28, 2026, Bitmain lists the S23 XP Hyd. as a futures product. Confirm whether the desired batch is open for ordering and its shipping schedule; an order listing does not mean immediate delivery. Official listing

Is a lower J/TH always the better choice?

A lower J/TH figure reduces rated electricity use per unit of hashrate, but overall mining economics also depend on purchase price, cooling infrastructure costs, electricity price, uptime, and pool fees, so J/TH should be weighed alongside these factors rather than used alone.

Does PPS+ guarantee stable BCH income?

No. PPS+ reduces the effect of pool luck on the subsidy component, but BCH earnings still depend on accepted mining work, network difficulty, transaction-fee income, and applicable fees. BCH price affects the fiat value of those earnings, not the BCH quantity by itself. PPS+ explanation

Can one ASIC switch between mining BTC and BCH?

Yes, where the pool supports it. ViaBTC's One-click Switch lets miners choose BTC or BCH in the pool settings after configuring the required Smart Mining endpoint. Setup guide
