Using hashcat with GPUs¶
NVIDIA GeForce RTX 4070 Laptop (AD106M, 8 GiB)¶
Using CUDA gave me a performance boost of 6x for the SHA256 hash-rate.

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.
