Is it possible for Ryzen 7 5800X3D to get Ryzen 7 5700X efficiency? If so, how?

Go to solution Solved by WereCat,

5800X3D is one of the most efficient if not the most efficient CPU on AM4 platform. There is no reason to really adjust anything. You can always set a negative Curve Optimizer offset to get lower temps and somewhat lower power usage as well but other than that, not really necessary to tinker with it.

 

Not all motherboards allows you to adjust Curve Optimizer in the BIOS but most should be able to with new versions. Otherwise you're stuck with the in-OS solution which AFAIK is tied to Windows only.

You can set the offset as low as -30... anything lower than that won't apply. Also have in mind that this moves the voltage/frequency curve so that you get higher clocks at lower voltages so it affects stability. You have to be lucky to be 100% stable at -30 offset. I recommend to start at -15 and slowly go up from there.

 

You can also set different offset for individual cores but that's just a time consuming hassle, not really worth it.

Hi, i like the ryzen 7 5700X efficiency, but i still hope i get those extra L3 cache since it seems to help for workload in linux (https://www.phoronix.com/review/amd-5800x3d-linux ). Too bad there's no Ryzen 7 5700X3D.

 

Well, from what i've heard, 5700X is basically an underclocked 5800X. If so, how can i achieve the 5700X efficiency with 5800X3D? I prefer if the solution is OS agnostic, but solution for linux is a priority. The easier and safer the solution, the better. I don't need it to be the most optimal efficiency, though it would be great. But, stability is still prioritized, since this is for work.

 

So, is there any setting to change like nvidia-smi? Or do i need to change the settings from BIOS? I never really underclock a CPU before. Oh, and my motherboard is Asrock B550M Pro4. I won't worry about expiring the warranty, but of course i don't wanna to break the CPU.

 

Anyway, thanks

The 5800X3D and 5800X differ a lot, it's not just the added L3 cache it's the clocks and voltages too. The 5800X3D runs lower clocks than the 5800X, just looking at the clocks it's close to the 5700X already.

You can't make a 5800X3D as efficient as a 5700X. You could underclock it, undervolt, and it would be better than stock, but q 65W TDP with it simply isn't possible.

Ah, i see. So 5800X3D is already efficient on power, but because the stacked L3 Cache it becomes hotter. And even if it is consuming more power, that is because the 3D cache and not the result of higher frequency, is that correct? Well i don't really mind the temp, just the wattage. If it is already efficient then all good i guess. Although, does 5800X3D power efficiency is same or atleast close enough to 5700X? Haven't bought it yet, might affect my decision to buy it later. Thanks

58X3D is a 105w part. It already is efficient. My X3D runs cool, and is easy to tame. Some people are not so lucky I guess..

Undrvolting as an option? 

Edit: ah mentioned already...

I edit my posts more often than not

Well, guess i'll try the curve optimizer thing. Any tips on that? Thanks

-30 all core, save and exit.
