Hello all, I recently setup jellyfin on my RPi 4 with an external HDD attached and after a few tests I decided to move on. On ebay I found a refurbished Fujitsu Mini PC with a Pentium G4560. It is way cheaper than the Lenovo ThinkCentre M720q (with a G5400T) which I saw being recommended a lot.
My question is:
how does the higher TDP of the former 54 W with a base frequency of 3.50 GHz compare to the latter with a TDP of 35 W for 3.10 GHz in a real world scenario running jellyfin?
For now I will continue using my external HDD because the prices for new drives is too high for me.
The thing that matters more than the TDP is how much power they draw at idle. It’ll likely be idling or turned off more than it will be on. And even when on, it probably wont be hitting its max TDP just playing some media unless you’re transcoding to 4k or something.
Is there a percentage of the TDP which is usually the idle power draw?
No, they’re almost entirely unrelated. Almost all CPUs will idle close to 0 W (with correctly working drivers). The main idle power contribution comes from the mainboard and other devices (e.g. disks). The Mini PCs you mentioned should have a very low total idle power, probably below 10W.
Check out Wolfgang on YouTube, he has some great videos on the topic: https://youtu.be/Ppo6C_JhDHM
Unfortunately no, which can make it a pain to figure out. You’d have to research the CPU itself.
Gamers Nexus reports 44W at idle with the G4560 which is already more than the G5400T’s MAX TDP of 35W, so it’s a pretty significant difference.
Assuming the RAM and other components are similar, I’d go with the G5400T system.
