You never ever want to skimp out on the power supply, there is a reason Intel, Nvidia and AMD have suggested wattage ratings for their hardware.. The rule with these things is that it is always better to over spec the power supply than under spec..
It is somewhat of an insurance policy to have a PSU that can handle the expected load with some breathing space.. Also not all power supplies are good, some are great while others are cheap garbage..
Another good thing to have is a UPS, it is great for those times when the power does go out saves not only your stress but your computer as well..
Yeah it has me wondering and I do find it strange that the 3060 has more vram than the 3070, 3070Ti and the 3080, 3080Ti seems like a weird thing to do but a case of who knows..
If I had to guess? My theory is that the RTX 3060 was originally intended as a 6 GB card.
However, Nvidia released and announced the Geforce 30 series at the start of September 2020. At the end of October, AMD announced the RX6000 series - where *none* of the GPUs announced had less than 16GBs, and their performance was really giving the Geforce cards serious competition.
At that point, changing the direction for the 3060 Ti probably wasn't viable - that came out only slightly over a month later, in early December, so production would have already been in very heavy swing. The 3060 was the first card that Nvidia could actually respond with, and in terms of design, upgrading the board from using 1 GB GDDR6 chips to using 2GB GDDR6 chips is fairly simple. (A lot of modders have actually done the same with other cards - it usually works on a hardware level, but then has a load of driver and firmware issues, but Nvidia can obviously solve that).
I'm not entirely sure why though the current rumours indicate they've abandoned the earlier concepts of a 16GB 3070 and 20 GB 3080, although it may be that they simply don't think they needed to. While the -80 cards are their flagships, they're selling as fast as they can make them even without the extra VRAM, but the -60 cards are their bread-and-butter where they really didn't want to lose ground to AMD.
However, I'm not an industry insider, so that is rampant speculation.
Hi!
I finally was able to order a GPU and it is a... ASUS TUF RTX3060 OC 12GB
The price was reasonable for this times and I'm really happy. Fingers crossed that it will arrive soon.
Which means you've actually ended up with the exact same model as I have, the TUF OC version. It's a big card, but if you've got the space for it, the large heatsink gives excellent full load temperatures; it's not summer here yet, but I'm expecting it to do well even on hot days.
How much VRAM you need is entirely up to what you make. Since you are just starting out, it is extremely hard to predict what you will likely use until you just sit down and do it.
Since you have a 3060 now, you could possbly sell your 5700 and get that money back, if you haven't already. You could then in turn invest in another GPU. One nice thing about Iray is that you can throw all the GPUs you can it at, as long as each GPU can fit the scene. Your x570 can hold 2 GPUs. You just need to make sure they will physically fit (that sure would suck) and that your power supply can run them. In this situation, you would almost certainly need a bigger power supply to do mutiple cards.
This is also where the power supply talk comes into play. With a 3060, you don't need much. But having a larger power supply gives you more options down the road. With a bigger power supply you could add a second card to your system and vastly increase your render speed. It doesn't even have to be a 3060, either. You could put a 3080 in there with your 3060 if you wanted to. In this example, the way it works, is if the scene you create uses less than 10GB on the 3080, it will run with your 3060. If by chance your scene is larger than 10GB, but still less than 12GB, then the 3080 will not run while the 3060 does. If you exceed 12GB of VRAM then neither card will run. That is basically how VRAY works with Iray in a nutshell.
Windows uses a little VRAM itself, so the trick here would be to have the 3060 running the monitor and the 3080 as the secondary card. This would give the 3080 as much VRAM as possible so it can fit the scenes.
Well it is already April 2021 and launch of the 3000s was in August 2020 and you have to ask yourself looking at the current prices and lack of supply if you aren't better off blowing the 3000s series off until they do another die shrink and up the RAM with their next set of GPUs because the truth is those crytocurrencies are going to get squeezed sooner or later. They can't maintain what they're doing.
