Does anyone have a photo of the backside of an RTX 3080 XC3 Black, where the backplate would be on higher-end cards?
I'm wondering if the backplate is just there for show on these cards or if it provides any kind of passive cooling benefit.

I heard that the Black doesn't have a backplate.
As to cooling, I've always (and I mean always) found removing a backplate is better for cooling the backside of the card - but it's not a big difference. With that said, I have a big case with very good airflow with two 200mm fans blowing right at the GPU.

That's correct, the Black does not have a backplate. The reason I want to see a shot of the PCB there is to try and ascertain if the backplate really serves any purpose beyond cosmetics. I also have a case with great airflow and I intend to undervolt so I'd probably be fine with a Black.

Go to any of the EVGA 3080/3090 non-black product pages and you will see...

As with most cards in the past, it typically provides more aesthetics than function on 3080 cards. The backplate also provides an extra measure of protection in case you drop something or accidentally bang the back of the card while installing the card or other components. Similarly, it may also help to keep the PCB straighter and distribute more weight to the other side of the card in comparison to a card without a backplate. It does pull some heat away from the PCB and the back of the card, but it's not going to be the reason your card runs at 70C vs. 75C.

I am not asking for a photo of the backplate. I want to see the PCB (under the backplate on non-Black cards).

Here's a picture of my 3090 FTW3 with the backplate off - the 3080 won't have the VRAM chips on the back like the 3090 does. Edit: lemme edit my serial number off of that.

Thanks, that’s pretty much what I figured. The XC3 Gaming is my card preference, but if I have a chance to buy a Black I may still do so. Mostly worried about the reports I’m seeing of the GDDR6X running HOT (100C+) on these cards.

I wonder how much the backplate heat pipes do to cool the card

Miniscule at best - they don't follow the VRAM chips, rather cut a thin swath over two of the three banks.

Thank you for sharing arestavo, that is quite helpful.
The XC3 and FTW3 appear to use the same backplate, so especially given that the 3080 doesn't have the GDDR6X modules on the backside of the card where additional heat dissipation may be beneficial, the backplate is not a must-have for me.

Bump...I've got both the black and xc3 ultra in 3080. I can attest that there's a 4-6 degrees in the vram temp between the 2 with the Black version being the one running hotter. I may consider an aftermarket backplate. Does EVGA sell a OEM backplate?

i don't think it has anything to do with the backplate. there's not any thermal pads between the backplate and the card. just the standoffs where the backplate is screwed to the card.

How about core temp , does the backplate from the xc3 ultra fit on the black edition card

Just wondering if you know for fact there is no thermal padding between the backplate. I am not saying you are wrong. I dont have a 3080. Reason I ask is because my EVGA RTX 3070 XC3 Ultra had thermal padding between the stock backplate and PCB. Got a pic if you would like to see. Just seems strange a 3070 would have the padding and not a 3080. I believe there is a thermal advantage to having a backplate. Especially an active backplate. Any high-end card would benefit from one. The stock backplate on my 3070 got hot enough you would burn you fingers when gaming. Same as the EK backplate on the 3070 now with the EK waterblock. And yes, there is a ****-ton of thermal padding under it as well. This is true for my RTX 2070 Super Black as well. It didnt have a backplate stock, but the EK backplate on it now gets super hot when gaming. You would burn your fingers if you held them there. The more ways to dissipate heat from those chips, the more chances of higher and smoother clocks. Some cases with poor airflow might hinder the removal, but the backplate is certainly going to pull the heat if properly installed. Even a card that didnt have a backplate from factory will benefit. Not only that, it hides and protects a hideous and vulnerable PCB. Cheers, just sayin'
