For a future setup, the 12700k and Asus TG H670 Pro WiFi D4 would pair well with a high-end CPU and M.2 motherboard offering plenty of expansion slots, SSDs, PCIe lanes, and USB ports—without shared connections. For cooling, aim for a cooler with a similar thermal output to match your current setup. Regarding RAM, a 64GB, 3600MHz CL18 configuration is solid; AMD typically performs better with four sticks, so consider that if possible. Let me know if you need more details!
5900X is the closest with any half decent B550 board paired with it. If you want something on AM5 instead, there isn't really a direct competitor as the 7700X is a bit slower while the 7900X is a bit faster. The 7900 non-X with stock power limits might be that, though I forget exactly what the performance characteristics of that chip are off the top of my head. It's complicated. On DDR4 it was better with dual rank, which was generally easiest to obtain with 4x8GB compared to 2x16GB, though 2x16GB dual rank was still generally easier to use. On DDR5 you want to avoid 4 sticks if possible. If you're going AM4, get some cheap 3200 CL16 kit as spending any more on RAM doesn't make sense. If you go DDR5, 6000 CL30 is usually the best value.
CPU choice depends on whether you're focused on gaming or productivity. A 12700k offers a bit more performance than a 5700x3D in gaming terms, while a 7600 would likely follow closely behind. For productivity, AM5 chips with eight cores seem reasonable, with 7700 and above being a safe bet. Intel CPUs generally range from a few to several additional cores or threads compared to AMD, making the comparison especially nuanced for productivity tasks.
It relates to various aspects such as market segment, price, performance, release date, etc. The meaning changes depending on what you're comparing. Right now, a 5900X seems most relevant, but it wouldn't make sense to buy it if the 5700X3D exists.
On socket AM4, your options depend mainly on the PCIe lanes provided by the chipset and the CPU. Combined with the 20 PCIe lanes from the CPU (15 for video card slot, 4 for first M.2 connector), you have a limited number of lanes to work with. For instance, with the B550 chipset, you typically retain around 10 PCIe lanes, which can be arranged in an x4 configuration with one M.2 slot, plus some x1 slots, or you might use just two lanes for the second M.2 connector. On AM5 sockets, there are now 24 PCIe lanes available from the CPU (28 total, but 4 reserved for the chipset). This means up to 8 lanes could be free for M.2 devices, depending on whether the motherboard uses them for additional USB or wireless cards. With B650 chipsets, you get 8 PCIe 4.0 lanes and up to 4 PCIe 3.0 lanes (if SATA ports aren’t used). Keep in mind that some images may be inaccurate; actual configurations vary. If you need many lanes, consider x670 boards, though they tend to be more expensive. For example, the cheapest available is the Gigabyte X670E Aorus Pro X at $385. The motherboard supports 4 M.2 ports—2 from the CPU and 2 from the chipset(s)—plus extra x16 slots in a few configurations.
Here’s a rephrased version of your message:
Thanks for the feedback! I didn’t manage to reply to those questions earlier. To start, my goal in setting up an AMD PC is mainly about testing, so matching thermal performance is key, with speed coming second. Therefore, I want the CPU, motherboard, and RAM to be as close as possible to the 12700K, Asus TG H670 Pro Wifi D4, and Patriot Viper Steel 2x32GB 3600 MT/s CL18.
To note, my CPU doesn’t seem too sensitive to overclocking, and it handles high temperatures without a big drop in performance. Using AM4 will be cheaper, but I won’t have a system that can keep up with future upgrades via PCIe Gen 5 or the newer features in AM5. Based on what I’ve heard from other tech experts, if I want something comparable, I’d need a 5900X or 7900X, paired with an X-based motherboard—preferably from ASRock since I’ve had issues with MSI’s customer service (though they did process my rebate without issues).
Between the options and another expert I trust, it looks like getting something similar would require either a 5900X or 7900X, plus an X motherboard, ideally from ASRock. I’m also wary of MSI’s reputation for pushing back on support, especially after Black Friday.
As for an X motherboard, I have four SSDs already, so it makes sense to include more in this build—though it’s not strictly necessary. Plus, I’d like the benefits X offers. TL;DR: If things go wrong, I’ll save this info for next year or later when I can make these purchases.
Explanation: My situation is tricky because Amazon and their support team (Sedgwick) are creating complications in a subtle way. They might try to influence me in ways that could affect my work, like threatening legal action or putting me on medical leave. I’ve already had to cancel a lawyer who wanted to help with a work injury claim. There are also other challenges, such as upcoming elections.
If everything works out, I plan to buy the CPU, motherboard, and RAM during Black Friday. I won’t buy from my current employer because of their unethical practices, so I’m looking for better deals from vendors like NewEgg or MicroCenter. I’ll likely write another thread about this topic once it’s settled.

You can find four SSDs on a B650 board. It's not very common, but it's cheaper than buying an X670 setup. Some boards also offer comparable thermal solutions, like the 7900X. The heat output will be higher due to AMD's denser chips and the thick AM5 IHS, though power usage matches the 12700K closely.
The 7900X could remain more efficient than Intel, though further evaluation is needed.
