High clock speeds are not the same thing as high wattage, they aren’t even really related, or very closely associated. We have no idea what the power usage of these processors will be. They could even end up being more efficient than previous processors, doing more instructions in a shorter period of time then powering back down to idle sooner on the same workload. Yes people might decide to throw more work at them as a result, but that’s not the CPU’s fault, that’s a people problem not a hardware problem.
They’re not found in traditional PC’s and are attached directly to the motherboard itself. They’re meant for mobile / embedded but are quite popular for servers in the selfhosting community due to their low power usage, price, and performance. It’s comparable to a i5-7500T in terms of performance (so not that fast), but it does have better video encoding acceleration which makes it suitable for streaming video. Due to the availability and prices of Raspberry Pi kits, these are often chosen instead for simple servers because mini-PC’s with it can cost the same as a Raspberry Pi kit.
Not even close to true, as others have said we even have chips from AMD that use less power and are faster than even their last gen versions. The 9700x has a tdp of 65w while the 7700x last gen version of this same like is 105w. So no this isn’t true at all.
IF all else remains constant. Which it doesn’t, and isn’t.
Do you have any idea how significant of an improvement it is for AMD to bring their process node to this level? All the variables going to be different here, and it’s too early to tell what that means until we see the actual silicon.
Correct. I never stated anything different. I was replying to the statement that “high clock speeds and high wattage are not related” when clearly frequency affects the power output in a linear fashion. Of course changing a manufacturing process is going to likely change the capacitance but the biggest savings in thermal has been the decrease in voltage as the process have shrunk.
I don’t get the downvotes though. I posted an accurate, relevant formula to the discussion and stated a factual statement.

P=C*V2*f
Power increases linearly with frequency.
2008: Core 2 Quad Q9400 - 4c4t, 2666Mhz @ 95W TDP
2023: N100 - 4c4t, 3400Mhz @
122W6W TDPI mean, a few years ago we had 1ghz CPUs with a 60w TDP. now you can do 3 or 4 or sometimes even more with the same tdp. it’s not all about the power.
The N100 goes up to 3.4GHz and has a TDP of 6W
wow that’s insanely impressive! I haven’t seen any of those chips in the wild yet so I wasn’t aware of it. super cool stuff
