PC Processors

Product specs at   https://www.amd.com/en/products/apu/amd-ryzen-5-2500u#product-specs   do not list AES at "Key features", while for example for   https://www.amd.com/en/products/cpu/amd-ryzen-7-pro-1700x   it does mention AES.

I'd like an (affordable) AMD cpu for a router/firewall/low end VPN server and for the VPN it is absolutely necessary to have something which compares to the other cpu manufacturer's AES-NI. The difference can be over 300% in performance.

Internet searches have been rather inconclusive and none of the sources have been AMD itself, so cannot really be trusted.

Only "Pro" series CPUs have an AES co-processor.

I'm conflicted after reading   https://en.wikipedia.org/wiki/AES_instruction_set   which mentions that all Zen architecture chips support AES-NI, that would include 2500U too.

But at least I found an official AMD mention of AES-NI on this Pro security features page:

According to CPU World that APU does support AES : https://www.cpu-world.com/CPUs/Zen/AMD-Ryzen%205%20Mobile%202500U.html

But not sure if that is what you are asking.

All Zen processors support AES-NI.  It's only going to be mentioned specifically as a key feature if they're trying to punch up security.

The 2500U has about 4.6GB/sec throughput with AES.

Thanks, seems it's time for a new power router! So done with consumer brand cr*p  routers.

How do you determine AES throughput? Is there data on AES/AES-NI throughput for different AMD processors available somewhere?
