More is better. Here my values at home:
Intel N3050 4x 1.6 GHz in an internal firewall with external Tor
application. Internet connection download 50 MBit/s, Upload 10
MBit/s.
Internal LAN performance: 90 MBit/s
My own downloads are near 50 MBit/s (less time, most time 20...30MBit/s);
Uploads near 8 MBit/s in peaks; Never theoretical limit reached.
My personal usage drives the internet line to full power, but Tor
as my MIDDLE RELAY doesn't use the full internet line power. It is
dependend from the cabability of the guard/exit partners. Cpu load
is less then 20%. The traffic is symmetrical IN/OUT.
My other external middel nodes doesn't use the full internet line power too. The cpu load is less then 10%. The hardware ist a single VPS cpu 3GHz with 512 GB RAM. This was the minimum of provider offer.
Take a look on
https://atlas.torproject.org/#search/node49
node49 is my home middle node. node49a/b are external VPS with 100MBit connections. The usage is about 5-10 MBit/s. Cpu load about 10% in peak.

I have tried a Banana Pi Pro 1,2 GHz Allwinner A20 -> 10 Mbit/s max (debian)
Beaglebone Black 1 GHz AM335x -> 12 Mbit/s max (debian)
Intel NUC5CPYH Celeron N3050 1,6 GHz to 2,16 burst -> 5 Mbit/s max (OpenBSD)
So I need something quite a bit more than I have already tried ;-)

I'm a little surprised that this kind of question is not documented anywhere, or at least I have not been able to find it.I have only found others asking the same question as me without getting a good answer.There was a quite exhaustive discussion seven years ago:
This one got closed before a good answer:
I am prepared to pay a pile of cash for a computer that I will dedicate to run a relay.I have a 100 Mbit/s symmetric connection.What should I buy?I don't want to buy something that has a too slow CPU that is not able to push enough traffic, but I also don't want to overkill and get a huge electricity bill.
Sebastian,How much CPU does your relay have/use?

Subject: Re: [tor-relays] What kind of hardware do I need for my relayHi Farid,I'm running my Guard / Relay on a VPS with only one core and 512MB RAM. Its also hosting a blog, my own mailserver and is member of pool.ntp.orgI haven't encountered any problems so far. It's also connected via 100MBit/secYou can see the stats here: https://atlas.torproject.org/#details/F381D6294A93A0078B76D0DCA332133CF5C8F687 I experimented a bit in the last weeks with being a bridge, but I now I'm back as a Relay... therefore the performance charts are not as high as they have been at the end of last year.

I have been running low powered middle relays for a few years.Now I think it's time for a small upgrade.I haven't looked at computer hardware for a long time.What is the cheapest and most power efficient CPU/motherboard that can saturate 100 Mbit/s as a Tor relay?
Thanks.
