I purchased a 5600x and B550 Tomahawk. Initially it came with outdated BIOS, causing USB problems. After updating the BIOS, I noticed spikes in ping while playing FPS games. My old 2013 Intel laptop didn’t have this issue, so I’m considering swapping everything for an Intel 11600K/KF. It might be cheaper now, though I’m unsure about the motherboard compatibility. Since my 5600x throttled to 95°C with a stock cooler and PBO, upgrading to a better cooler would help. The "14nm vs 7nm" debate feels like marketing hype; my experience suggests it’s not worth it. Right now I’m frustrated with this setup and have many concerns. Anyone else have done something similar? Did you switch from AMD to Intel? I don’t think the extra performance is worth the hassle.
What speed does your RAM run at? The AMD stock cooler performs adequately, meeting the basic requirements similar to Intel's. Your latency problem might be resolved with additional driver updates. AMD offers a driver update package for their chipset and network components—check your motherboard site for downloads. It’s fine to reset everything and try Intel again. I used to be an Intel enthusiast before switching to AMD when the 3000 series launched, and I’ve stayed loyal ever since. There were some adjustments to make, but AMD is definitely impressive now.
The main USB issues I experienced were on Windows 11 after updating the BIOS (F13 beta), whereas I didn’t face any problems on Windows 10. PBO seems to be overclocking, which might explain why a stock cooler isn’t helping much when you push it further.
Others already explained about PBO, overclocking and the stock cooler, so let me just give my 2c about the 14nm vs 7nm thing: A smaller process node means that a CPU will consume less power to achieve the same results, which means that you can have the same level of performance using less power, or maintain the power consumption and get more performance (or something in between). Since it's a smaller node, it also means that the chip itself is more dense and smaller, meaning that there's less surface area for heat to be exchanged with your cooler. So, while it consumes less energy, extracting the heat from it is harder, specially in short bursts where there isn't enough time for proper heat exchange.
The new bios update resolved the USB connection problems. The ping jump issue bothers me. It might not be connected to AMD, so I’ll keep an eye on it. If it works and isn’t related to AMD, I’ll leave it as is. I get it about PBO, but honestly it’s just frustration from all the things. I’ll wait a bit and see what happens.
I suggest considering that your ping jump problem might stem from your network controller, which isn't directly tied to AMD but could affect other systems with the same controller (like Intel boards). It's possible some ASUS models had Ethernet controller issues on Windows, though I'm not certain about your setup since it's an MSI board. You might want to investigate your specific Ethernet controller instead of focusing solely on the motherboard or CPU. You could search for similar issues using a relevant controller name.
AMD had a recognized problem where the USB would disconnect upon the 5000 launch. The issue was resolved later through BIOS updates provided by various motherboard makers.
The motherboard comes with BIOS that includes AGESA version under 1.2.0.2, which is why I’m checking if it still works properly. At first I thought it might be due to the MSI board using Realtek instead of Intel LAN, but then I realized I was connecting unrelated components.
According to common knowledge, the tomahawk features two Ethernet controllers—one with 2.5GB capacity and another with 1GB. You might want to test switching between them if needed.
