ASIC device usually has much better mining performance than graphics card. It is more energy-saving and has a much higher hashrate.
The Bitmain Antminer L7 (9.5Gh) was produced by Bitmain and released in 2021. This miner consumes 3425W, producing 9.5 Gh/s of hashrate with the scrypt algorithm, which makes this device almost (if not at all) useless. We do not recommend buying this device for mining nowadays.
