Minecraft Server CPU/Specs advice
Not sure if this the correct place to post this buuut:
regarding MC Server PC hosting i'm not 100% on CPUs. I know to aim for:
High single core 3.5Ghz+ Base Clock
4+ Cores (Hyperthreading and 6+ Cores preferable)
Intel 6th Gen and newer for 2400mhz+ Memory support (I tend to focus builds on Intel/Nvidia rather than AMD... - dont dislike AMD... just know Intel and NVidia parts better tbh...)
SSD PCIE 4x4 (I know PCIE 3x4 probably sufficient but good for futureproofing ig...)
16GBs DDR4 2400mhz+ RAM (typically ill do my builds with 32GBs)
That being said there are still a fair few CPUs from Intel 6th and 7th gen which meet the above "spec requirements" but being of an older CPU generation do they release lose much else?

ghz means nothing by itself, use proper benchmarks
how many people are you trying to have on the server, modded etc
typically around 5 people active average. at peak 10/15 people though.
modpacks typically around 200 - 400 mods... but capable of running any version (typically from 1.7.10 to 1.20.1 - any modloader)
most packs will (almost always) run with mods such as Gregtech/Create (1.16.5+ packs), AE2 (most packs), etc...
most packs will include mods that can be heavily automated (which ive heard can heavily use up server tps without a decent CPU)
realistically, I'd avoid most intel processors that are more modern. They have really bad multi core scaling (dealing with multiple servers at once).
If I'm buying new hardware, I'd aim for a ryzen 5800 or better.
If I'm buying used hardware, I'd aim for an HP elitedesk with an i5-8500 or i7-8700

HP EliteDesk 800 G4 Mini - SFF - Intel i5 8th Gen - 16GB RAM - 250G...
Case: HP EliteDesk 800 G4 Mini - SFF. 1 x HP EliteDesk 800 G4 Mini. Modern Office PC i5 8th Gen - 16GB RAM/250 GB SSD/Win11 - Triple Monitors. Connections: USB, USB-C, Audio Jack. Dell OptiPlex Office PC i7 6th Gen - 16GB RAM/250 GB SSD/Win10 - 3x23" Monitors.
probably want the SFF model instead of the mini model, as the mini uses a laptop CPU vs the sff model that uses a desktop CPU
at oldest though should I keep 6th Gen and above or keep the CPU Gen at a higher gen
also around what Gen does the dip in multicore scaling become "more noticeable"?
all of them aren't great, but I know that the i9-9900 CPUs aren't amazing for minecraft hosting
as in, getting a ryzen 3000 or 5000 based machine would be overall better than a similarly priced intel i9-9900 based machine
12th to 14th gen might be fine, but those have degridation issues
in my personal experience of running 30 nodes with ~500 clients or something, we never had issues with faulty CPUs or anything like that, and we primarily used AMD servers. We did have a big issue of Samsung SSDs dying though.
you stole what I was going to say π /jk
Are you home hosting?
currently ya
Is this for a network, friends,?
I highly recommend Intel Pentium i586
300 Mhz clock rate
This is good too but kinda expensive
https://a.co/d/81XQdHq
Intel Pentium Dual-Core E5300 2600MHz 800MHz 2MB SLGTL CPU
CPU INTEL PENTIUM DUAL-CORE E5300 SLGTL 2.60GHZ/2M/800/06
(I'm joking btw this is a horrible suggestion do not buy it it's a waste of 3$)
Yikes. Thatβs a lot of mods. Youβd probably be looking at a high end ryzen 5 to begin with
friends only server currently.
current spec is:
i5 12600K
Corsair LPX 32GBs (2x16 3200mhz) DDR4
4TB (Patriot Viper VP4300 Lite)
iGPU (UHD 770)
MSI B760-P DDR4 II ATX (probs gonna swap it to a Z- board tho with a Thunderbolt 4 header...)
Doesnβt look too bad
Is that your primary pc or just a dedicated server
dedicated server (currently running GTNH on it rn - peak player count is abt 5 players currently)
Are you having issues with it?
and the most important spec in your case?
Power redundancy?
Internet Provider?
nah. CPU rarely goes past 20%. and memory no further than 50%
Would downsize jvm memory to 16g xmx then
Donβt waste the extra performance to GC processing
currently has a Corsair RM650 Gold PSU and im on a 900mbps plan with TalkTalk
I pray itβs not wifi?

Corsair RM650 (2023) 650 W 80+ Gold Certified Fully Modular ATX Power Supply (CP-9020280-NA)
thats not what i meant by power redundancy
you need a UPS or some systems to keep electricity in case of an outage
Bro, he is hosting at home
all by supposed CAT8 ethernet cables altho I did check with some people on TomsHardware and they suspect the cables i got are likely still CAT6
Thats exactly why he needs it
Most homes donβt have two fucking sets of independent power sources
Cat6 is fine
so just have a powerful enough UPS
So i assumem its a residential plan
i meannn... i aint got one now buuut could invest into one l8r on...
what wouldja recommend I get? (I do already have 3 PCs running currently)
not business or dedicated
Then why does he need a second power supply?
outages
UPS =/= PSU
You can plug the ONE psu into the ups
Yes
Gosh how many ASNs does talk talk have
Stop getting people to buy useless shit, regular pc motherboards does not have a place to plug a redundant psu in
And itβs not useful in opβs case

Doesnt seem that bad ig
fairly well connected
Bro thats not how it works
900mbps is also more than enough for a friends server, op does not have the need to buy a business plan
This is an UPS
Big ass battery
you plug your pc to it
if electricity goes out battery kicks in
oops I might have read psu
its not just about the speed
Apologies lmao I thought you asked op to buy a 2nd psu
residential isps usually tend to have network issues and will limit packet rate
no that would be kinda stupid
depends on the isp i guess, never had that issue with mine Β―\_(γ)_/Β―
Are you home hosting?
Yeh
Gbit bidirectional with telus
....
mfw I pay for 1.6gbps but still only get 100mbps up
I donβt see that being a huge issue tho for a server with like 15 players
isnt telus like a carrier
bruh
shouldve said that first
its just residential ISPs are not designed for hosting and can cause issues
Ye he did say it
i did not read that
:marketplace:
They do both
people home hosting always worry about the specs
but I dont :minecraftTroll:
so they end up with a 7950X and then their light goes out every 5 minutes and their ISP has 30% packet loss half of the time
Dell servers with 10yro cpus still works okay
i meannn... how i see it...
ya overspec ya dont rlly gotta worry too much abt performance (altho it probs will cost ya more tbf...)
You can end up worrying still about performerance if the power isnt stable and if your isp causes everyone to have 600ms ping
Thatβs some horrible packet loss. Iβve tested my packet loss at home, never seen it go above 0.0%
I can confirm that even a xeon E5-2667 v2 is not enough to run ATM10
your isp is a carrier....
Nah I donβt run atm lmao
I mean, in the UK, every ISP would be considered a carrier with that logic... It's all just openreach here...
Β―\_(γ)_/Β―
We also have old ass coax here
not the docsis
wouldnt that be more a memory speed issue tho (like dont ya want ddr4 2400+ - preferably 2667 or faster)?
idk, its just general recommendation having at minimum a business line because residential isps can be residential ISPs
Single core bottleneck
Differs.
3.3Ghz single aint fast enough???
whats the lowest ya can go for then? (ngl i thought upto now that any singlecore 3Ghz+ was enough...)
ghz != performance
Speed doesnβt correspond to performance
I have this old pentium thingy in my Cisco firewall that runs up to 3 ish ghz, performs like shit
I made my i7-3770k run at like 5.5GHz in the past... didn't mean it was fast....
just drop in a DDR5 threadripper and call it a day
β οΈ
as you said
its better to overspec
like i get that:
- 4 cores+ (preferably 6+ cores altho at 8+ Cores performance doesnt differ too much)
- 16GB ddr4 2400 (preferably ddr4 2667+)
i would if ddr5 wasnt nearly double the price of ddr4 tbh... (at least in the UK)
High core count is normally for multiple instances. You just need like 3-4 cores with high single core performance
Unless you run things like folia, but itβs off topic
then drop in a DDR4 threadripper
3990X or smth
β οΈ β οΈ
a 5995WX should be enough
you can get some pretty cheap ddr5

although realistically, I'd go AMD (7000 or 9000 series) over intel
my residential ISP (AS2856) only has one upstream :(
imma assume a lower Cas Latency (CL) aint too major then for servers (normally on DDR5 id aim for CL36 or DDR4 CL16)
cas latency is relative to clock speed
Not really
so 3000mhz cl20 and 6000mhz cl40 are the same
they have the residential AS and the only upstream is their Carrier AS
so in reality its
