- 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.

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

AMD Ryzen 9 5900X Boxed
https://tweakers.net/pricewatch/1618232/amd-ryzen-9-5900x-boxed.html
A 12 core / 24 core thread beast. However due to it's high price new, it would only make sense to go with this CPU if we were to pick the one of the more complete V&A options.
Price: 259 euro (Second hand around 150~190 euro)
AMD Ryzen 5 4600G
Between writing the BOFH meeting notes and this "BOM", megekko stopped selling this CPU and now the only option is buying it for 180 which is a nope.tar.gz.
