Mining difficulty has greatly increased over the last few halvings, causing it nearly impossible for an ordinary device to predict the nonce values of a transaction.
ASIC miners bring greater efficiency, which saves you a lot of money.
Mining a block has always been a race that results in the fastest competitor to win. A lower device like a PC or laptop is hence not suitable for everyone who is using an ASIC.
To achieve the same goal, say mine a block, they need much less energy.
