7-Zip Compression benchmark with settings of Test: Compression Rating. EPYC 9754 2P: SMT On was the fastest.
7-Zip Compression benchmark with settings of Test: Decompression Rating. EPYC 9754 2P: SMT On was the fastest.

7-Zip (de)compression performance was scaling fairly well with SMT on Zen 4C.

Stockfish benchmark with settings of Total Time. EPYC 9754 2P: SMT On was the fastest.

Stockfish benchmark with settings of Total Time. EPYC 9754 2P: SMT On was the fastest.

The Stockfish chess engine also enjoyed some speed-ups with SMT.

OpenSSL benchmark with settings of Algorithm: SHA256. EPYC 9754 2P: SMT On was the fastest.
OpenSSL benchmark with settings of Algorithm: SHA512. EPYC 9754 2P: SMT On was the fastest.
OpenSSL benchmark with settings of Algorithm: RSA4096. EPYC 9754 2P: SMT On was the fastest.
OpenSSL benchmark with settings of Algorithm: ChaCha20. EPYC 9754 2P: SMT On was the fastest.
OpenSSL benchmark with settings of Algorithm: ChaCha20-Poly1305. EPYC 9754 2P: SMT On was the fastest.

The OpenSSL cryptographic library was enjoying some benefits out of SMT on the AMD EPYC 9754 processors.

Liquid-DSP benchmark with settings of Threads: 512, Buffer Length: 256, Filter Length: 512. EPYC 9754 2P: SMT On was the fastest.
