Need help on CPU decision

[Ahmad313]

Hello everyone, 

 

please allow me to pick your brains on a CPU decision,

I am building myself a new Skyreach mini 4 system, 

For the Skyreach there are many limitations that affect the choice of CPU, and in my case only 1 GPU model in the world works with it. 

So cpu cooler has to be very low profile, max height 40mm I think, and the power supply is 400W so tdp has to be low for both heat and power. 

my previous build worked very well for me, it was a ryzen 7 3700x with a Noctua NH-L9a-AM4 cooler. Power and heat are behaving perfectly fine. 

For the new build, there no sweet spot cpu like the 3700x, so here's the available options:

- ryzen 7 5800x: 8cores, 32mb cache, pci4.0, -- only works in ECO mode as neither the cooler nor the power supply can take it under normal operating mode

- ryzen 5 5600x: 6cores, thats the problem, i don't only use it for gaming so i'd prefer an option with 8cores at least

- ryzen 7 5700g: 8cores, but 16mb cache and pci3.0 only, isn't a strategic update in my opinion. (power and heat are fine)

- intel i5-12600k: it seems they draw much more power than the 65w tdp ryzen cpus and thus can be a problem for my power supply and noctua cooler. and it seems there is a win10 compatibiliy issue. 

 

Any advise on which direction to take is much appreciated, if there a better suoted CPU (amd or intel) that i haven't mentioned please let me know. 

Many thanks

 

PS: my aim is to build a new system while maintaining the old one, this isn't an upgrade of the old one

You might be able to conclude something from this: https://www.techpowerup.com/review/intel-core-i9-12900k-alder-lake-12th-gen/20.html

That's very helpful thank you , I am going to dive into it to see if I can make a final decision

12600K is the best deal from the choices you listed assuming current going prices, but you are adopting a new platform so there might be some teething issues. If you're looking for something more stable, I would lean towards the 5800x, mainly due to small relative price difference.

If you can wait a few months lower power Alder Lake cpu should become available.

Thanks Jonathan, actually i'd love to go for the 5800x but the problem is its a gamble with my setup. its over powered for my setup and i am really unsure if it can handle it. the same goes for the 12600k actually. it seems like im stuck between 5600x and 5700g.

I really hope so as the current set of CPUs in the market do not have that sweet spot of the 3700x

If you tend to run one program at a time the 5600x, will be fine for now. If you like keep programs open, or multitask quite a bit, I would lean towards the 5700g. The 2 spare cores should give you a smoother experience overall.
