👁 SVT-AV1 benchmark with settings of Encoder Mode: Preset 13, Input: Bosphorus 1080p. EPYC 4585PX was the fastest.

👁 SVT-AV1 benchmark with settings of Encoder Mode: Preset 13, Input: Bosphorus 4K. EPYC 4585PX - No AVX-512 was the fastest.

👁 SVT-AV1 benchmark with settings of Encoder Mode: Preset 8, Input: Bosphorus 4K. EPYC 4585PX was the fastest.

👁 SVT-AV1 benchmark with settings of Encoder Mode: Preset 5, Input: Bosphorus 1080p. EPYC 4585PX was the fastest.

👁 SVT-AV1 benchmark with settings of Encoder Mode: Preset 5, Input: Bosphorus 4K. EPYC 4585PX was the fastest.

👁 SVT-AV1 benchmark with settings of Encoder Mode: Preset 3, Input: Bosphorus 1080p. EPYC 4585PX was the fastest.

AVX-512 was of some help with the SVT-AV1 video encoder.

👁 OpenSSL benchmark with settings of Algorithm: RSA4096. EPYC 4585PX was the fastest.

👁 OpenSSL benchmark with settings of Algorithm: AES-128-GCM. 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.

AVX-512 on the AMD EPYC Grado processors also allowed for some dominating victories with some of the OpenSSL workloads.

👁 John The Ripper benchmark with settings of Test: MD5. EPYC 4585PX was the fastest.

👁 John The Ripper benchmark with settings of Test: HMAC-SHA512. EPYC 4585PX was the fastest.

👁 John The Ripper benchmark with settings of Test: WPA PSK. EPYC 4585PX was the fastest.

Similarly with the John The Ripper crypto application there were huge gains to find with making use of AVX-512.
