Top selection for cost-effective power usage.
I'm looking to set up a server rig and was curious about the optimal CPU choice. I need something fast but efficient, avoiding high power consumption. I'm aiming for a price under 300 per watt, preferably lower if possible without sacrificing performance. The main focus should be on performance and power efficiency.
you can find used workstations around 2,2699 v3 models for about 350 dollars.

Interesting point—5600 and 7600 both have a 65W TDP, but their power draw might differ. It’s unlikely they consume the same amount, especially with such a big jump in speed. Still, being efficient matters, even if it’s faster. Edited April 21, 2023 by podkall edit
AMD’s approach isn’t ideal—it feels misleading and oversimplified. Many people rely on buckets because there’s been a lot of change in Intel components, making it hard to grasp the real power usage. The heat generated by the CPU is released as waste, not useful work. A 65W TDP for AMD translates to an 88W PPT, which is frustrating since both heat output and power delivery matter. Still, AMD has a valid argument: in everyday use, short spikes to 88W are manageable with efficient cooling. A cooler handling 70W will work well, even if the entire chip briefly reaches 88W.
