* Used 5900X + ROG Strix + 64GB (€350)
** +207% single-core, +505% multi-core
** Good perf-per-€ and perf-per-Watt
** Still very efficient (33.33 SC / 374 MC per Watt)
** Ideal for compute-heavy, multi-VM, and long-term performance
** No ECC and needs a cooler + GPU, but the cost margin gives you room to grab a €60 NH-U9S and cheap GT 710.

Latest revision as of 20:15, 18 July 2025

  • The AMD Ryzen 5 4600G is cheap CPU (€117) from 2020 with 6 cores/12 threads and does 65 watts TDP. Its multithread rating is 15,987 and single 2,652.
  • Currently Erratic is a 6 core / 12 thread from 2014 with a TDP of 85W and a multithread of 7,776 and a single of 1,688.
    • It's double the performance for less power!
  • If we want _more_ we could opt for a better Ryzen CPU.
  • The AMD Ryzen 7 5800X is €138 and a multithread of 27,740 and a single of 3,446 which is a 256.7% increase but at 105W TDP.
  • Motherboard would be something like €132.
  • We could maybe take our 64GB DDR4 ECC with us if we get a motherboard that supports ECC (the 5800X supports ECC).
  • The 5800X does _not_ have a GPU. And only CPUs with no iGPU support ECC. Means we might need a low power card for boot/install.

(semi) complete Tweakers.net vraag & aanbods

Epyc 7282 16 core + ASRock Rack EPYCD8 met IPMI + 64GB DDR4 Registered ECC

Listing on Tweakers

ASRock Rack EPYCD8 specs

Total Price: 500 euro

Pros:

  • server grade
  • motherboard has a LOT of options (oculink, 4x pci-e x16, M2)
  • With our current memory we might be able to go to 128GB DDR4 ECC
  • With the available SATA we could use it to combine Harmony and any GPU machine we want in the future
  • Multithread of 30137 and a single of 1945
  • Multi-threaded is ~290% faster than current Erratic

Cons:

  • Single threaded performance is only ~16% faster than current
  • 120 watt TDP so it slurps way more power
  • 500 euro is a hefty price

Ryzen 5900X / ROG Strix B550-F Gaming / 64 GB DDR4 3600Mhz aangeboden

Listing on Tweakers

Total Price: 350 euro

Pros:

  • Comes with motherboard + cpu + memory
  • 12 cores / 24 threads monster
  • 3.5x faster single core than current, 4.6x faster multi-thread
  • 2.5gb ethernet
  • 2x M2 slots
  • 6 Sata connections (we use 5)

Cons:

  • With 105w we are staying within the same TDP range, however performance per watt is significantly higher and newer arch + modern chipset etc means the CPU and entire system itself is way more efficient at idle.
  • Anus motherboard
  • 5900x has no IGPU
  • We will have to get a new (beefy) cooler.
  • Motherboard doesn't seem to do (n-buffered) ECC ram

Upgrade kit: gigabyte x570s aorus master / 5900x / g.skill 64GB aangeboden

Listing on Tweakers

Total Price: 450 euro

Same CPU as the above listing, so the same pros & cons apply. Will mostly concentrate on the motherboard. Both listings have the same memory speed as well.

Pros:

  • gigabyte motherboard
  • Support for un-buffered ecc
  • 2.5Gbps lan
  • has 3 pci-e 16x slots and two M2 slots.
  • 6 Sata connections (we use 5)

Cons:

  • 4x 16GB memory = more power usage
  • costs 100 euro more
  • Also will need a beefy cooler

conclusion

  • Used 5900X + ROG Strix + 64GB (€350)
    • +207% single-core, +505% multi-core
    • Good perf-per-€ and perf-per-Watt
    • Still very efficient (33.33 SC / 374 MC per Watt)
    • Ideal for compute-heavy, multi-VM, and long-term performance
    • No ECC and needs a cooler + GPU, but the cost margin gives you room to grab a €60 NH-U9S and cheap GT 710.
