Need Advice on Upgrading Mining Gear

[Polgord]

I’m currently running an older Avalon miner and thinking of switching to something newer in 2025. I want something with higher output but I’m also worried about power usage and heat. I’ve heard the latest generation hardware has improved on both. Is there a model that’s really standing out this year in terms of tech advancement?

The recent models are definitely a big step forward, especially when it comes to power efficiency and cooling. I found a great list comparing the top bitcoin mining hardware 2025 and dug deep into real use-case reviews. WhatsMiner M60S consistently came up as a strong option—liquid-cooled, good airflow, and 186 Th/s. On the other hand, Antminer S21 packs a punch but runs hotter and louder. I also liked how some newer models use modular power supplies, making them easier to repair if anything goes wrong. You’ll want to match the machine to your power capacity and cooling setup. One tip: don’t get swayed by hash rate alone. Sometimes a lower-rated machine with high efficiency gives better ROI over time.
