These CPUs aren't consuming 250W all the time. Those are peak numbers.
Both Intel and AMD are providing huge efficiency gains, too. Rumors show the new i7 13700T Raptor Lake part can have a 35W mobile TDP and still outperform a Ryzen 7 5800X: https://www.tomshardware.com/news/intel-13700t-raptor-lake-allegedly-faster-than-5800x-35w https://www.tomshardware.com/news/intel-13700t-raptor-lake-a...
Speed scales nonlinearly with power. These high TDP parts are halo parts meant for enthusiast builds where it doesn't matter that the machine draws a lot of power for an hour or two of gaming.
It's also trivially easy to turn down the maximum power limit in the BIOS if that's what someone wants. The power consumption isn't a fixed feature of the CPU. It's a performance/power tradeoff that can be adjusted at use time.
- jorvi 4y agoIts still pretty terrible from an optimal performance viewpoint. I can undervolt my 3070Ti by ~100mV, dropping performance by ~6% but dropping temperature by about 10C, or 13%, and dropping fan speed from PS3 to inaudible for anything <90% load.
- RedShift1 4y ago> for an hour or two of gaming U gotta pump those numbers up, those are rookie numbers.
- TakeBlaster16 4y agoJust adding to what you said, a 24-core CPU won't get anywhere near peak power usage during gaming. Most games only use a handful of cores. The only way you'll approach it is with parallelizable productivity work like video encoding or compiling code.
- ForOldHack 4y agoMy nephew, B, got his 16+8 i9, during Path of Exile, to peak at 250W, and use all 24 cores. He is running at 5.2Ghz, and using air cooled. We are not sure at all how it uses e-(efficiency) cores, when it has 16 p-cores w/ hyper threading, but it all did show up in the new dark mode task manager.
- wellthisisgreat 4y agoWhat’s a new dark mode task manager?
- oktwtf 4y agoThe latest Windows 11 preview finally reads the system default paint allowing “dark mode” rendering the ui with dark background and light foreground.
- brokenmachine 4y agoWhat a time to be alive!!
- hulitu 4y agoSo like in win 95 when you use a "dark theme". What an achievement. Wait, you can also set background colour. /s
- seritools 4y agoPoE is one of the few games that actually makes use of lots and lots of cores/threads.
- staticassertion 4y agoAny idea what for? I feel like PoE doesn't involve that much compute other than what would be offloading to the gpu. Maps are static, and I would have assumed that mobs are primarily computed server-side based on some sort of loosely synchronized state. I guess I could imagine a few threads for managing different 'panes', a thread for chat, a thread for audio maybe? It's hard to think of 24 independent units of work. I'm not a game dev, just used to play PoE and curious.
- ace2358 4y agoCould it be the gpu driver/framework? I thought DX12 and Vulkun were meant to be cpu optimised and be able to use heaps of cores.
- Symmetry 4y agoI think you'll find that modern games use many more cores than they used to since mainstream consoles have all moved to being octa-core for the last two generations and you have things like Vulkan better allowing multi-threaded graphics code.
- TakeBlaster16 4y agoMany more cores yes, but 100% CPU usage should still be rare. If your game uses 100% of a 24C/32T processor, it will run poorly on a "mere" 8-core CPU, and most of your target audience won't be able to play it. You're right though, these aren't your grandma's single-threaded games anymore.

Don´t let the TDP of T-models fool you. Power consumption to reach boost clocks can peak up to 100W for T-models of the previous generation, and the 13700T probably needs to run close to that to outperform a 5800X.
- lr1970 4y ago> These CPUs aren't consuming 250W all the time. Those are peak numbers. But they require a heat-sink management designed for that peak. And it is insane. Try to keep microwave oven under 100C :-)
- zeusk 4y agoYour toaster uses more than 250W, microwave ovens are far above at 1-2kw
- epolanski 4y agoI don't really second this perspective. CPUs and GPUs keep getting hungrier and that is just not where we should be heading. I wish the perf increase didnt keep coming along consumption increase each gen.
- bhedgeoser 4y agoYou can clock down a 7950x to 105W and it will be 37% faster than a 5950x
- epolanski 4y agoI hardly care, I don't want that heat in my room anyway.
