oh no... anyway

Already now with PCIe 4.0, we have manufacturers peppering the board with retimers so they can stick to cheap PCB materials.

I don't even want to think about the price tag if they had to implement 5.0 now already. Maybe things will get cheaper in the future.

When they, oh I ment before they get cheaper they implement a new technology like pcie 5.0 to make it expensive again. Lol. Never fuckn ends.

I bet that Genoa (AMD) and Sapphire Rapids (Intel) will have a lot of PCIE 5.0 lanes.

PCIE5 will boot from your M.2 SSD a little bit faster.

I doubt there are huge real-world benefits. No shade intended, change my mind?

they could be usefull for the cpu-chipset connection so you can have more bandwidth for the chipset slots, m2 and so on.

other than that, hard to find them needed in consumer space.

usually they release these updates well before they become wallet friendly so that there's plenty of time for users and developers to get their hands on the hardware. its a foundational thing rather than an immediate performance upgrade like a CPU or GPU would be.

pcie 5 just feels like its coming too fast because there was a big delay in releasing pcie 4.

Honestly I feel like we're pretty much at the point where for like 95% of users out there the speed of SSDs have superseded their needs.

ID: h9v9jep

Faster is good. But NVME really needs to catch up before PCIE5 helps a lot.

Theoretical max speed of the 4xPCIE4 interface is 16gb/s. For 4xPCIE5 its 32gb/s. The WD PCIE4 SN850 highest measured speed is 7,000 MB/s (WDS100T1X0E).

It would probably be usefull for video editting and other work stationy tasks where you might be moving around hundreds and hundreds of gigabytes, but probably not for most people no.

I seriously doubt that since pcie5 ssds don't exist

Coming soon though. Tom's Hardware: Samsung Teases PCIe 5.0 SSDs: Coming in Q2 2022

Maybe we can get back crossfire support. mGPU in DX12 failed to gain traction.

ID: h9x9lvd

From what I heard Alder Lake doesn't even use it's PCI-E 5.0 lanes for storage. Those stay at 4.0.

I read somewhere that PCIe 5.0 on the Intel boards will be for the GPU slots only so no difference for the storage slots

ID: h9xbccc

Heard the same thing. Though in theory you could sacrifice some lanes for one of those M.2 expansion cards.

not surprising considering 4.0 is very far from fully saturated and 3.0 is just starting to hit its limits but is still good for gaming use

ID: h9uvnmj

Consumers are not even close to hitting PCIe 3.0 limits. Not even gaming is reaching 3.0 limits. There's another generation if not two before even gaming will be bottlenecked by PCIe 3.0.

ID: h9uzq5b

Console are utilizing pci4.0. It will make its way to pc gaming soon.

ID: h9t7d0g

The most powerful x16 GPUs only gain a ~10% improvement from PCIE 4.0 so only barely over half the bandwidth of PCIE 4.0 is actually being used now.

If we changed our standards to PCIE 5.0 now the highest end GPUs would be using less than a third of the PCIE x16's bandwidth which is wasteful, the only practical number it would change is the price tag.

ID: h9t8y6y

Pcie 5 does matter a lot if you plan to bifurcate the pcie slot and get a equivalent of 2 pcie 4 slots.

8 : Anonymous2021/08/21 20:54 ID: h9txrzv

What consumer facing devices will there be that will utilize PCIE 5 by the time Alder Lake comes out? Or once Zen 4 comes out? MAYBE the Intel Arc GPUs? But things that stress PCIE graphics bandwidth are a very niche use case.

pcie5 with 600 series MB launch, would be way too early for home users, even professionals.

10 : Anonymous2021/08/22 16:29 ID: h9xbke0

There is no need for it, if you are the 0.0000000000000001% of people who might need more bandwidth than PCIe4 offers for stuff like rendering or ML then just get another computer and run them as a cluster.

I hope we wont experience the same shit again.

Segfault cpu, bad ram support and locking PCIe 5.0 to 700 or 800-series mobo.

ID: h9ugdid

Why do you need it tho?

After a few boots from my XPG S70, Win10 decided that an 8sec boot time was too fast and started scanning my 10TB HDD EVERY BOOT.

PCIe 5.0 would probably make Windows decide that TRIM & Defrag was needed on non-ZNS drives, to maintain a 30sec boot time.

Who cares. They should focus on availability of the existing parts already.

ID: h9xbg2a

Existing parts are readily available.
