Question Do I really need PCI 4.0?

[vwcrusher]

Hi All, while thinking through what my new system might contain, in particular R7-3700X or 3800X, or i7-9700K or 8700K I began wondering if I really even need a faster PCI buss. What benefit will be derived? Will I actually notice the speed difference? Cost benefit? I have read that the Samsung 970 EVO Plus NVMe drives are fast and reliable. Should I wait for drives that support 4.0? If I do not need 4.0 are the Samsung drives the best fit?

To put the above in context my use includes Lightroom and some gaming. I am not terribly budget constrained but I prefer long term value. One constraint is my monitor: 1440p 60Hz.

Thanks for the perspective....

not unless you get a new PCIe 4.o SSD. nothing else can utilize it at this point. Little to no gain in any available modern GPU will be noticed.

Thanks for the reply; Interesting, are you suggesting then that a PCI 4.0 NVMe drive will be noticeably faster for my applications?

 

[Diddly]

Right now PCIe 4.0 does nothing. GPUs don't need it. doubt the're much real world benefit for NVMe drives. I'd like to think motherboards and NVMe cards might go PCIe 4th gen x2 lanes which would allow twice the number of M.2 cards to be used compared to PCI 3rd Gen x4 lanes and have the same overall bandwidth.

So, PCI 4.0 is not a factor for choosing a CPU....is that what you are implying?

If that is the case, are the drives I noted in my original post an appropriate fit for my intended applications? I suppose what I am asking is: do I need that level of performance to notice a difference?

depending on your workloads, NVME PCIE 4.0 may not offer you great returns at their current price.

This is mostly going to benefit MULTIPLE PCI-E devices taking up more lanes and the bandwidth from large data transfers.
If you have a basic system with one nvme ssd, and a graphics card I doubt there would be any noticeable difference.

 

[vwcrusher]

Interesting - That makes things a bit more complex w.r.t. CPU, but certainly simplifies the storage situation.

Are the drives I noted above worth the premium? Will I notice a difference in performance from a less expensive one, say the Corsair MP510. I should note the storage strategy included a 500GB drive for W10 and applications, and a 1TB drive for data.

again, thanks.

Thanks for the reply; how above (reference my last post) two PCI storage devices plus GPU?

My advice would be to revisit this thread after the technology has been released and benchmarks have been observed.

Noted and of course I will make no purchases until I see data, but I thought that pre-analyzing the storage system strategy might eliminate some variables......

that is a pretty good setup for the storage to start with. You can always add more and larger devices later

Thanks...are you referring to the Samsungs or Corsairs?
I do have an external for back up...

 

[Deleted member 14196]

the drives should be fine

Just to clarify, I wasn't talking about storage. I was talking about throughput. PCI-E 4.0 has nothing to do with capacity.

Gigabyte has already teased some sequential read specs for it's PCI-e 4.0 NVME SSD, at a mere 4975 MB/sec or so....(naturally, that's 1400-1500+ MB/sec more than the 970 EVO Plus, but, it remains to be seen what real-world advantages these speeds could give in opening/apps, file copying, installations/shutdowns/bootups, game launch times, etc...; could be some staggering numbers, and, for those with two of these installed, some awesome storage transfer speeds....)

PCI 4.0 may have advantages over PCIe 3.1 but it remains to be seen what that will equate to outside of synthetic benchmarks and the .01% use-case where extreme bandwidth will show a noticeable difference.

Yep, and why I posted the question......I just wondered given my anticipated use would it make any detectable difference in performance.

Yes - see comment below.....still don't know
