Question about PCIE 4.0

Hi Guys,

 

I would like to know if you can use a rtx 3080 for say in a z170-a motherboard. I believe the board is pcie 3.0 and I heard the new RTX 3080 requires 4.0. 

 

Is the card going to be limited by the 3.0 pcie x16 slot ?

 

Thanks for any details on the subject. 

 

-----------------------------------------------------

 

Edit : I see this has been answered already in other posts. We need to see how much the card would be limited. Could be bothering or could be close to none. Who knows... I guess I will wait to see !

 

Cheers guys sorry about that

No, it supports 4.0. It can be used just fine on a PCIe 3.0 - bus.

looks like not check their video again there is small writing on bootom of screen that they test it on i9 cpu so thats pci 3.0

only question now is how bi different will be loading times from ssd running on pci 3.0 vs 4.0

We won't know until someone actually develops a game that uses the technology.

The CPU will limit the 3080. 4c/8t is just not enough anymore for an increasing number of games. And Z170 tops out at just 4 cores.

Yes I am aware of it but how much is what I am curious about and in which games really ? Also I would probably upgrade in a close future

As per this video :
 



It seems like in 4K the 2080ti is fine with a 6700k and in 1440p it's kind of a ~10% bottleneck in average, as some cases there is no bottleneck for that game, and some other game there is around 10% better performance on the 8700k

 

Since I play in 1440p.... and not 4K, I should expect serious bottleneck with a 3080 i agree....

 

Anyway, I will look at benchmark before buying :P

bottleneck with 3080? I though gpu will be using ssd directly instead using cpu

I think I understood that the SSD data willl reach the GPU directly instead of going into the RAM.

 

I would need to rewatch the video.

 

Anyway, it's all about your resolution. Pretty sure a 6700K do well with a 3090 in 8K.

comparing 2080 vs 3080 will be difficult because new gpu work different way. just cpu will be up to 20% less stress then before i cant wait to see benchmarks hope they will be out soon. :)

Nvidia themselves tested the cards to highlight performance increases over last-gen on PCIe 3.0. I'd be worried about the CPU, not about not having PCIe 4.0.

Digital Foundry has already had the chance to test the 3080 vs the 2080:

Will see how much it bottleneck and probably will go for 10700k if needed i am using 1440p 144hz gsync resolution monitor with a gtx 1070 that I bought new on release or like 1 month after release... so.. I was patient enough to skip 2000 serie (rofl) so now I wanna go for it xD
