7.1.2 slower than 6.1.2 for SHA512

[zamgold]

It should not, please update to latest CUDA version 12.9 or higher.

Hi. I installed CUDA version 13.0...But 7.1.2 slower than 6.1.2


hashcat (v7.1.2) starting

CUDA API (CUDA 13.0)
====================
* Device #01: NVIDIA GeForce RTX 3080, 9400/9875 MB, 68MCU

OpenCL API (OpenCL 3.0 CUDA 13.0.78) - Platform #1 [NVIDIA Corporation]
=======================================================================
* Device #02: NVIDIA GeForce RTX 3080, skipped

Minimum password length supported by kernel: 0
Maximum password length supported by kernel: 256
Minimum salt length supported by kernel: 0
Maximum salt length supported by kernel: 256

Hashes: 1 digests; 1 unique digests, 1 unique salts
Bitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates
Rules: 1

Optimizers applied:
* Zero-Byte
* Single-Hash
* Single-Salt
* Uses-64-Bit
* Register-Limit

ATTENTION! Pure (unoptimized) backend kernels selected.
Pure kernels can crack longer passwords, but drastically reduce performance.
If you want to switch to optimized kernels, append -O to your commandline.
See the above message to find out about the exact limits.

Watchdog: Temperature abort trigger set to 90c

Host memory allocated for this attack: 1267 MB (61238 MB free)

Dictionary cache hit:
* Filename..: /media/ntfs1/dictionary/dict.dic
* Passwords.: 855284955
* Bytes.....: 10027391827
* Keyspace..: 855284955

Cracking performance lower than expected?

* Append -O to the commandline.
  This lowers the maximum supported password/salt length (usually down to 32).

* Append -w 3 to the commandline.
  This can cause your screen to lag.

* Append -S to the commandline.
  This has a drastic speed impact but can be better for specific attacks.
  Typical scenarios are a small wordlist but a large ruleset.

* Update your backend API runtime / driver the right way:

* Create more work items to make use of your parallelization power:
