I'm currently using my Ryzen 5 3600 backup PC after building a new one with a 14900K and DDR5. The 3600 is feeling really sluggish during everyday tasks like browsing Chrome or moving windows around. There's noticeable lag and slow rendering of large pages. My setup isn't bloated or misconfigured, so I'm trying to figure out what's causing the slowdown. Is it because Windows 11 might be better suited for CPUs with more threads, or could it be an issue with the clock speed? I know the 14900K has a significant edge in this department, but could Windows 11 be optimized for newer hardware at the expense of older models like mine? Are there any tools or methods to evaluate my Windows and desktop performance?

I have a 3600x and I find it works great on Windows 11, especially after a fresh install. Make sure you have the right AMD chipset drivers and your power profile set to Ryzen balanced to get the most out of your CPU.
You're really comparing different tiers of CPUs here. It's like comparing a Honda Civic to a Ferrari! The 3600 can clock to around 4.2 GHz, but the 14900K hits around 6.0 GHz with way more cores. The technology gap between them, even with the same release year, makes a big difference!
Thanks for the suggestions! I’ll definitely look into debloating Windows and making sure my drivers are up to date. I'm hoping that can boost performance a bit.
The Ryzen 5 3600 is a solid mid-range chip, but it does fall behind newer tech like the 14900K. It's built on older DDR4 tech, and while it's comparable to other CPUs from its generation like the i9-9900k, the 14900K is significantly more advanced. Expect a major difference in performance, and keep in mind it'll likely draw more power too!
My R5 3600 runs just fine on Windows 10 for web browsing. I’d first check if you're low on memory or if the CPU is overheating. Sometimes, it’s just about not having enough RAM or thermal throttling that slows things down.
You should check out this guide: https://www.reddit.com/r/AMDHelp/s/C8enAFjsWQ. It might have some useful tips to help speed things up.
Well, yeah, the 14900K is definitely faster than the 3600. That's to be expected! My first thought is to check your Windows settings. You might want to run a debloater tool to optimize performance—I've had good luck with ShutUp10 on my PCs.
