doman18 Posted October 7, 2018 Posted October 7, 2018 (edited) Hi guys. Ive seen this forum from time to time in search results. And now i finally registered to ask a question. Im looking for very cheap (under 80$), extreemely powersavvy pc with AES support. This machine will work in my home 24/7 as OpenVPN server only (no other stuff). I pay the bills myself so energy is my main concern. I already own 3 pc's , 2 monitors, 2 smartphones, and 3 network devices and this time this new machine needs to be almost unnoticable in my energy bills. At first I was thinking about Raspberry Pi 3 or RPi 3 + but i found that its bottleneck is gigabit NIC which is poorly implemented. In the other hand AFAIK ODROID C2 has significantly better gigabit NIC and AES support as well. I also did some research in terminals, SFF/USFF pcs etc but most of them: a) have AES, are cheap but arent power efficient enough (Dell, Lenovo, HP SFF/USFF PCs) b) are cheap, very power efficient but don’t have AES (Atoms and similar) c) or have AES, are powerefficient but also are quite expensive (Celeron J series, N series or AMD Kabini) . I found that old AMD E1-2100 has also AES support, are very power efficient and netbooks with them (like ACER Aspire V5 V5-123) are quite cheap. Im not interested in PC Engines boards, routerboards, NUC, BRIX, ZBOX or similar things as they are over my budget. So can anybody could help to compare these two (AMD E1-2100 and Amlogic S905) in terms of crypto performance and energy efficiency? Or point a better solution (Orange Pi One Plus)? As for Odroid im concerned about its AES support. Because geekbench shows very poor results for AES single core tests (OpenVPN is single core).https://browser.geekbench.com/v4/cpu/search?q=S905 And just look at E1-2100http://browser.geekbench.com/geekbench3/574666 But i hope its just a matter of Android used for benchmarks and some stuff needs to be just compiled-in ...https://forum.odroid.com/viewtopic.php?f=61&t=2334 Edited October 7, 2018 by doman18
doman18 Posted October 7, 2018 Author Posted October 7, 2018 Well, in the meantime of waiting for post aproval i found a topic with nice comparison of values from this tool. IMHO this should be published in the first post of topic you linked. This reassured me about Orange Pi One Plus. At first i interested in it because excelent price but now i see significantly more powerfull in crypto operations. This is a dealbreaker. Also i found another interesting thing in this topic. Even though noone tested E1-2100 with sbcbench yet but Willmore published results about his i5-3220m. I compared it with AMDs cpu in cpu boss. There you can see AES results from geekbench. Then I estimated sbc bench result for E1 by calculation proportions. CPU==Geekbench== SBCBench i5 2230m == 2 140 000 == 630164 (for aes-128-cbc 8192 bytes) e1 2100 == 494 700 == x x = 630164 * 494 700 / 2 140 000 = 145 673 I dont know how close to reality my asumptions are but at least they give me some picture
