not everyone can get this I suppose

If you upgrade to 5900x, CPU performance will be double. If change platform you need to buy motherboard, higher cost or if maintain same cost then not much higher performance.

How about 3600 + B450? Thinking to upgrade because my cpu utilisation until 90% when I do many multitasking.

Just get 5800x or 5800x3D.
You might as well as get one complete CCD package.

Preferably 5800x3D due to its large L3 cache size. Cause Ryzen with one CCD has half memory write speed.

How bout 5900x? Cheaper then 5800x3d

Why not?
As long as it fulfil your needs for more threads and cores.
Make sure your B450 mainboard VRM is capable of handling 105watts CPU.


Dont limit yourself to AMD offers, you can consider Intel offers too.

I'm not sure what's the price for 3600 these days. Preferably you should upgrade to 5000 series since it's faster. Since you also going to get motherboard, check out Intel too, 12th gen only. AMD or Intel older gen, unless the price is a lot cheaper, not worth to get.

Last month I got my 5600 the price is just what, $10 more expensive? Makes it a no brainer

If can I just want to change on the cpu only. But also think about to change to i12 but the cost including mb is much higher.

Zen 3 5000 series B2 stepping are now much better than B0 and launch day Zen 3 models which were riddled with bugs. AGESA is also in a much better place than what it was in compared to Zen 3 launch. 1.2.0.3c if you're on Win10 and 1.2.0.7 if you're on Win11, these 2 work extremely well on the said OS.

Honestly now is a pretty good time to get Zen 3 if you already have an AM4 board preferably X470/B450 minimum, X370 while it works is still a little flaky.

If you already got AMD mobo, better to just upgrade CPU.

5800X or 5900X, not 5800X3D since your issue is high CPU usage when multitasking

you are not aiming for high FPS for a RTX 3090.

5800x3D is pretty difficult to get a la carte. Even if you get it, still costs more than a 5900x which is bonkers.

Other than that, 5800x3D is a mighty hot CPU as well.

Changed to 5900x, so far satisfy with the performance. Same programs open and cpu utilisation only 50%.

5900x becomes quite a beast if you're willing to push the FCLK to 1900mhz (assuming yours can hit that, otherwise even 1800mhz is great), tighten RAM timings and optimize the cores with curve optimizer.

There's quite a bit of unlockable performance from the CPU.

Is it okay to pair 5800X3D with air cooler like Dark Rock Pro 4 or must use AIO water cooler?

DRP4 is good enough. Doesn't stop the CPU from shooting to 80c for short periods of time even in gaming loads though, even if you use a 360 AIO.

Can't really give any valuable insight for air cooling the 5800x3d.. however I noticed that mine running pretty cool with my custom loop after using the PBO2 tuner desktop app.

I suppose this will be quite useful for those air cooling it as well.

And given that for the 5800x3d extensive RAM OC is hardly worth the time, (if performance is what you're having in mind) it's well worth to spend that time elsewhere and use it running corecycler to figure out stable settings.

Here's a decent guide on how to do it

PBO2 + CO is indeed key to low temps, not just for 5800x3D but for Zen 3 in general.
