Intel 13th Gen vs AMD Ryzen 7000 – Consider Your Options Think about what matters most for your needs before deciding.
The pattern you're observing resembles an inefficient fan curve on a liquid cooler. This causes the coolant to heat up and cool down slowly, leading fans to speed up and slow down in this unstable behavior. In reviews for air coolers, the frequency spikes immediately at the start of testing because the chip isn't hot yet, allowing the VRMs and CPU to manage briefly before stabilizing at a maximum frequency and power draw within the cooler's limits.
I wouldn't choose Intel right now because the 13th generation ends with its socket design, making upgrades impossible. I'm sticking with the 7900X since there are plans to upgrade it in the next couple of years. I expect to upgrade again to the x3d version later, keeping the same motherboard and DDR5 support. For the AMD side, I'll reduce the IHS and adjust my cooler mounts to fit, but I doubt I have the funds or confidence for direct die cooling to reach peak performance.
All I want to say is don't expect that AMD will make a thinner IHS for the X3D variation. The 8000 series CPU, maybe.... but the X3D one, nope. These IHS are mass ordered, and they are stuck with a crap load of them ready to be installed on newly made CPUs. I think AMD logic was that, DDR5 memory is costly and so is implementing PCIe 5.0 for motherboard manufactures to make (It will drop in manufacturing price as time goes on as DDR5, obviously), and so to save consumers money if they upgrade from AM4 to AM5, there is about $50-100 save by doing this, as most heat sink manufacturers aren't Noctua ready to send out upgrade kits. The problem is that if they wanted to do this, they could have supported DDR4 memory, and not have to push PCI 5.0 on motherboards. PCIe 5.0 isn't a selling feature today. We don't even have premium storage on PCIe to even consider, and GPUs aren't fast enough today nor tomorrow to take advantage of it. Heck the 4090 is finally using PCIe 4.0 bandwidth, but there is plenty of head room. Cheaper options (using PCIe 4.0 only) could have been made to help consumer save money. Or another option... reduce the CPU price. Crazy I know, but hey, guess what, they'll need to do it regardless thanks to Intel being less expensive, and apparently AMD Ryzen 7000 series aren't selling well either. I am not surprised by this news, as I also noticed that besides the 12 and 16 core variants, I have not seen any retailers being sold out of them... and even the 12 and 16 core that was ONLY on the first week. It's been in stock all this time. And I start to see retail bundles being made to try and help push the sale of them... the product just got released.
I mean thats what has been happening with the new 13900K. While the AMD chips dynamically boost, the 13900K just goes until it throttles, and then dials back. Hardware Unboxed showed that even on a 420mm Liquid AIO, the 13900K throttles even in gaming loads, doesn't even have to be an All-Core load, just playing CyberPunk 2077 is enough to throttle on the 13900K. Perhaps the behavior is garbage because the heat just ramps up too quickly and dynamic boosting just doesn't work? Keep in mind that if you run a 7950X stock out of box, it pulls around 180 Watts and the 13900K pulls over 300 Watts. Yes you read that correctly, the new 13900K is such a power hog that it consumes nearly DOUBLE the power of AMDs most powerful 16C/32T Chip. No wonder the damn thing throttles. Everyone is already struggling to properly cool Ryzen 7000 series, how exactly is the system supposed to perform when a 180W CPU is already maxing out your cooling solution and now all of a sudden you are asked to somehow deal with another 75% of wattage/heat load.
It achieves 300W by combining several factors. Under normal conditions it might reach up to 360W during stress tests, and the 7950X could exceed 300W in those cases. In gaming performance it likely doesn’t hit such high levels, as techpowerup reported an average of about 118W across its games. It’s also unlikely the device throttles significantly during gameplay, which might suggest a faulty mount or a misleading review.
