Hello guys!

I have a gtx 1660 ti and I saw it has 1500 cuda cores. What are does?

I also saw that a 3060 ti has 4800 cuda cores. Is it worth the upgrade? Or should I stick with the old one.

You can think of CUDA cores like CPU cores in a processor. The generic term is shader core. Generally the more shader cores a GPU has, the more powerful it is. NVIDIA just calls them CUDA cores for marketing reasons.

Cuda is NVidia's proprietary API for supporting compute cores or simply cores in its graphic cards. In simple terms its just the performance cores of a chip with NVidia code customisation as its NVidia hardware.

It is worth the upgrade if you need it and the rest of the machine can support it, specially the CPU and PSU.

Thank you for your fast answers! So it's like more power to the main core. For example Intel has more single core power than Amd. Or at least it had back in the day.

I didn't knew about the trophy to mark as solved. I thought only the administrator can make it.

What does transient spikes mean?

Ok, maybe I will upgrade the power supply unit, if I upgrade to the 3060ti graphic card.

Should I take one with more than 600 watts? You said there is probably a borderline.

And what is Atx 2.2 versus Atx normal?

There is nothing as normal PSU. They are all of one variant or the other. Too many to explain, better go through them yourself...

Transient spikes are short spikes of few milliseconds when the card draws almost twice the power of what it is expected to. This usually results in the machine shutting down due to insufficient headroom to absorb the spikes. A lot of 3xxx series cards suffer this problem. It is not guaranteed to happen but you never know. I would go with a good quality 750w just to be on the safer side. A bit of headroom is also beneficial for future upgrades.

Thank you for your answer. So Atx 2.2 is not the size of the box.

Will this be good for the 3060ti? It says something about full modular, while the 750 watts has semimodular.

Thats a good PSU but modular or semi modular has nothing to do with output and/or efficiency. That would still be pretty close to borderline considering the rest of your build. I would go with atleast 650w with that unit, just to be safe.

Ok. I don't know what modular means. That's why I thought the lower power one is better, than the bigger one.

So do you think for the 1060ti, I should get a 650 watts, even with semi modular stuff or no modular at all?

I don't want to have more than a graphic card or more than one ssd and one classic hdd. That's why I thought a lower one with full modular could be better.

Also, what is gold certificate and platinum certificate? Is the second one better? Or it is an overkill.

I was talking from the context of the 3060ti, not your current card.
Again, gold silver platinum etc. are industry standards which doesn't always reflect the true worth of a unit. PSU is a vast and complicated topic to explain in a few words. I would suggest that you do some research yourself.

with atx 2.x specs, there are no rules for transient spikes, both amd and nvidia can get really big transient spikes on some cards which some PSUs may not like, rule of thumb is to use atleast twice bigger size of PSU then you actually need
with atx 3.x, there are clear rules for transient spikes which every atx3 PSU must handle, that means you no longer need 2x bigger PSU, if GPU +cpu draws 400watts, 500watt atx3 is more than enough

So that means i can get even a 550 watt psu for the 3060ti?

I ment 3060ti, not 1060ti. It was a mistake. My current card is a 1660ti.

Yes, but ATX 3 is still pretty new and vastly unreviewed. Also not as prevalent everywhere yet. Alao. I don't think OP has the budget for it, not sure on that though.
