The RTX 4090 took 1 hour to crack strong passwords in the test


Tests conducted by a cybersecurity firm confirmed that the RTX 4090 can crack strong passwords in just 1 hour when using hash functions

In today’s computing world, video cards are components that go beyond mere professional or gaming use. GPUs can be used to accelerate complex tasks such as servers, data centers, research stations, and password hacking. In fact, one company’s tests show that an NVIDIA GeForce RTX 4090 can crack your password in 1 hour.




The estimate was carried out by Hive Systems, a company specialized in IT security which predicted the time it took for NVIDIA GPUs to crack passwords. The test was carried out using the hashing technique, a function that combines passwords by mixing them, making the hacking process more difficult.

In tests carried out with the Software Hashcat, the RTX 4090 took just 1 hour to crack strong eight-character passwords, with numbers, uppercase and lowercase letters, and symbols. This benchmark was run using the algorithm MD5, easier to hack. However, the next algorithm, bcrypt, showed severe difficulties for all involved.

Estimated time to crack passwords with NVIDIA GPUs on MD5
Just the number Small letters Uppercase and lowercase letters Numbers, uppercase and lowercase letters Numbers, uppercase and lowercase letters and symbols
RTX2080 Instant 6 seconds 24 minutes 2 hours 4 hours
RTX3090 6 seconds 13 minutes 52 minutes 2 hours
RTX4090 1 second 5 minutes 22 minutes 59 minutes
H100×8 Instant 2 minutes 7 minutes 19 minutes
A100X12 1 minute 5 minutes 12 minutes
A100 x 10,000 (ChatGPT) Instant Instant 1 second

The second benchmark highlights what the RTX 4090 would take 99 years to achieve this feat. However, it is interesting to note how the NVIDIA A100 GPU for acceleration, it has a lot of power, taking only 5 days to crack the complete password with the entire structure of the ChatGPTwhich has around 10 thousand examples of this component available.

Estimated time to crack passwords with NVIDIA GPUs in bcrypt
Just the number Small letters Uppercase and lowercase letters Number, uppercase and lowercase letters Numbers, uppercase and lowercase letters and symbols
RTX2080 2 hours Four months 92 years old 375 years 989 years
RTX3090 17 minutes 4 weeks 18 years 72 years old 189 years old
RTX4090 9 minutes 2 weeks nine years old 38 years old 99 years
H100×8 2 minutes 2 days 2 years 7 years 17 years

H100×12

1 minute 2 days 1 years 4 years 12 years
A100 x 10,000 Instant 3 minutes 11 hours 2 days 5 days

While it may seem alarming, Hive Systems’ research was not designed to generate panic. While it is indeed possible to hack and crack passwords with home video cards, this process is not that simple, as there are multiple security barriers to break down at different levels.
