Intel Core 2 Duo E8400 vs Intel Celeron E3300 Idle Power Consumption

[Surfer123]

Hey Guys,


I'm just getting into crypto mining. I have an old HP XW4600 workstation that I'm going to use as the basis for a mining machine. It has 4 PCIe slots so I'm going to build a rig with 3 or 4 RX570's.

The CPU in the computer is a Intel Core 2 Due E8400 3.06GHz. I have heard that these are quite power hungry and not particularly efficient. I have been looking online and I can purchase an Intel Celeron E3300 for $5.

I'm wondering would the E3300 use less power at idle to warrant the purchase and time spent to change the CPU?


Thanks in advance

I don’t think you will see much difference in power consumption.  Both CPUs have speed step technology, and the same voltage range. Personally, my first rig used an E3200, and it was cripplingly slow for normal tasks, even with an SSD.  Think you would be better off using the E8400 and trying to undervolt it.

Allow me to ECHO what this guy said. Don't concern yourself and waste time on things with very small details that will probably have little or no impact on your long term mining profitability. Instead focus on sourcing your hardware as soon as possible so you can finish building your rig and start mining! Remember that our days are numbered till ETH goes POS.

E7000s-8000s are burning around 80-90 W with motherboard included.

newer series are much more energy saving oriented.

For example G4000s are burning around 40-50 W with motherboard included.

It's lower than that.

that's with g45 motherboard with on-board video/220w psu. You can go even lower by doing bsel mod if you really want/need to.
