Switch to Ryzen 5900x and resolve power consumption concerns
Hi! Your upgrade to a Ryzen 5900X is impressive. It’s surprising how much power it consumes, especially with Eco mode on. Even at low loads, it draws around 45 watts when idle—way more than your old CPU. With daily use for work and hobbies, the total can add up quickly. Your previous model idled at 15-20 watts, but now it’s closer to 35-45 watts during video calls or streaming. If you’re looking to reduce power usage, consider checking BIOS settings, using power-saving features in Ryzen Master, or exploring energy-efficient peripherals. Most tips focus on high-demand scenarios, which isn’t your case. Let me know if you need help with anything specific! Thanks.
Ensuring your BIOS is current, having the latest AMD chipset drivers for Windows, and selecting a Balanced power profile leaves limited room for improvement. Non-G chips from Ryzen consume more power than their G counterparts since they lack a monolithic design. The 5900X features three distinct dies—two CCDs (Core Complex Dies) and an IO die—each requiring separate power, which reduces efficiency during idle or low-power operations. In contrast, the 5700G contains everything on a single die, including the iGPU, CPU cores, and IO components, making it more efficient for power-saving in idle states. The 5700G is also a laptop CPU built into a substrate, soldered for desktop use; PBO can push its limits further than Eco mode, though it will significantly impact multi-core performance. You probably won’t experience the same low idle power draw as with the 5700G.
How much does electricity cost in your region? Even with a rate of $0.50 per kWh, you're spending roughly an additional $8 monthly just to power your computer for 16 hours daily while using about 35W more on average. Based on how beneficial the 5900X is for your tasks, it could easily offset this expense since it operates more efficiently and is 50-70% faster than the 5700G at full capacity.
The improvements weren't as significant as I thought. The increased power consumption would have been manageable, but it would have added unnecessary cost. At €0,41 per kWh, the extra electricity would cost around €140 annually. That amount could cover a 7000 series chip with similar performance but better efficiency.
Are you using any RGB tools? You're running higher than me, and I said it's fine for the socket to deliver the maximum power to the CPU for PBO, around 255W plus a few watts. Typing this out, I'm at about 32-35W @ 32C.
