👁 ASTC Encoder benchmark with settings of Preset: Exhaustive. EPYC 4585PX was the fastest.

👁 WebP Image Encode benchmark with settings of Encode Settings: Quality 100, Highest Compression. EPYC 4585PX was the fastest.

👁 OpenSSL benchmark with settings of Algorithm: AES-256-GCM. EPYC 4585PX was the fastest.

👁 OpenSSL benchmark with settings of Algorithm: ChaCha20. EPYC 4585PX was the fastest.

👁 OpenSSL benchmark with settings of Algorithm: ChaCha20-Poly1305. EPYC 4585PX was the fastest.

👁 nginx benchmark with settings of Connections: 500. EPYC 4585PX was the fastest.

👁 nginx benchmark with settings of Connections: 1000. EPYC 4585PX was the fastest.

So for those that may have contemplated whether buying an old, used server platform like an EPYC 7601 server with higher core/thread counts and more memory channels would make sense versus going for a modern budget server in the EPYC 4005 series, hopefully these benchmarks were eye opening for you.
