PCIe Gen4

[AshSenpai]

Hey guys ,

 

I was wondering about the PCIe gen4 and I'm really confused about it 

 

is it only for storage (M.2 NVMe) or is it also for the graphics cards ?

I'd appreciate the explanation

thanks

Any PCIe device that supports it.

PCIe 4.0 will be able to handle anything PCIe 3.0 could. PCIe 4.0 is not a new standard, it's just a new implementation. It's both forward and backwards compatible, so your current cards will work in a PCIe 4.0 port.

 

Like PCIe 3.0, a manufacturer simply just have to provide a PCIe 4.0 standard on the IO card, question is if the IO card can take advantage of the increased bandwith.

is the nvme socket also could be pcie gen4 ??

will if nvidia release a gen4 card this year i guess intel will be screwed i was wondering if they left empty pins in the socket to enable pci gen4 like amd

Sure, NVMe and graphics card for instance.

afaik, gen 3 and 4 use the same pin, but different protocol

 

and intel might be screwed in marketing checkboxes, but i doubt the next gen GPU can even saturate pcie 3.0 x16 for normal gameplays

if they do, it would be a huge leap in performance, or next gen games are coded to be bandwidth intensive

Why would they release a card that only about 20% of the market can use?

good point,if next gen is really next gen that would benefits to use gen4 then im screwed cause i cant wait for my next build any longer i want it future proof i tend to upgrade rarely like buy the high end stuff and after 6 years upgrade again

it may not benefit them now but they might release it so that next year consumer will be aware of it and have an reason to upgrade for extra 40 fps i guess its just marketing

My understanding is a gen 4 card works in on gen 3 board

[Dr0y]

Like it was said before yes it's backward and forward compatible.  So yes a gen 4 card works in a gen 3 slot and vice versa. 

Also next nvidia gpu are supposed to be pcie gen4.

Also some motherboard manufacturer made z490 pcie gen4 compatible but for now intel don't have any pcie gen4 support on cpu.

I didn't know that z490 motherboards supports pcie gen4 but what i know is intel cpu dont lol thanks for that info i guess intel have to do something about it

Intel is just not ready for pcie gen 4 ... about the same as 10nm I suppose ...

 

Well if boards (some or all I don't know) can support it we could hope that intel bring it to the next line of cpu and keep the same socket.  Not that it would make any differences for gpu (maybe for the 3090 super ti super somethin somethin) unless the low end ones are being on pcie gen4 x8 and that then it matters a bit ... like the rx5500 xt if I remember correctly.
