Compare real-world energy consumption of an Intel i7-13700K against a Ryzen 7-7900.
Hello, I'm considering a CPU upgrade and am struggling to decide between the i7 13700k and the Ryzen 7900. The Intel 13th gen non-k paper release didn't meet my expectations, so I'm weighing these options. I've noticed most online discussions focus on synthetic load power usage, but that doesn't really reflect real-world needs. In my case, the CPU will mostly sit idle for 8-12 hours daily—handling web browsing, meetings, emails, light office tasks, and occasional video editing. Then it's used for gaming or streaming. I'm curious about actual power consumption data for these scenarios. Do you have any reliable real-world tests? I understand my usage patterns are typical, but I need a clear comparison. Thanks!
AMD clearly outperforms Intel in most power scenarios. The latest developments remain strong, especially in idle consumption. Both models will likely offer efficient performance.
Power usage is where the Ryzen 9 7900 excels, even though it barely trails the Ryzen 9 7900X and comes close to the Core i7-13700K in certain benchmarks. It only consumes 200W, which is 125W less than the X model and 186W below the i7. This data comes from the link provided: https://biz.crast.net/amd-ryzen-9-7900-v...d-you-buy/
Well, imagine you need someone to handle a task like this. I have a 1920x480 screen connected to my PC as an AIDA64 info panel display, CPU and GPU usage for testing. I'm running a 5900X while browsing and typing. The VPN is active, Chrome has 19 tabs open, and the CPU isn't idle—it's steady, using about 39 to 44 watts. Utilization stays low, hovering between 1% and 2%. The CPU temperature is only 29-30°C. If others use Intel or AMD chips, they might share their experiences. I've used Intel for 20 years, but this 5900X is my first AMD build, and I'm really impressed by its efficiency.
32 watts from a 12700 non-K. Still a significantly less powerful component.
true but i am running a 34 inch monitor an rtx 3080 also a pci card to run an extra gen 4 ssd along with 3 ssds attached to the motherboard another 2tb ssd mounted to a cheap pci daughter card for backups all whilst messing around replying here watching youtube a lots of tabs open in a browser and my VPN is running and i even have the game Eve Online ruunning in the background salvaging wrecks whilst I type this replyand still only 50.04 watts so that is a real test . everything uses a little CPU ????
I recently completed six missions in the game, letting other tasks handle themselves. Not ideal for gaming, but my CPU stayed stable between 78 and 87 watts. The sudden jump to 87 watts happened during intense combat against a large group of enemies. I’m not sure if this data is useful, but it seems my system handled it well. My power bills are also important since I’ve been unemployed since the start of the pandemic and am too old for new work. That’s why I keep an eye on my utility costs. I took these factors into mind when setting up my PC 18 months ago.
