Wonder how long for NVIDIA to catch up on PCI-E 4.0 (New AMD Navi cards are supposed to have it)

Even if we have PCI-E 4.0 Ready MB, with PCI-E 3.0 devices there are no actual improvement in bandwidth. I'm planning to buy Ryzen 3900x and considering between x470 and x570 chipsets. Probably I should wait for comparisons, x470 most likely will perform worse.

Ryzen 9 series supports PCI-E 4
x570 chipset also supports it
The SSDs and such will follow soon after the release of these two next month
Some "preliminary" ones announced already
NVIDIA will catch up (I am sure) to maintain the advantage

Why not the 3950X

I'm also in the (lengthy) process of acquiring bits and upgrading to 3900X / ASUS Crosshair VIII Hero X570. Can't find a board nor the cpu in Aus for love nor money at the moment. The 3900X seemed to be in a sweet spot for Mhz vs cores for non-overclockers.

I spotted a review of a PCIE4 nvme ssd last week (lost the link), the result was only a marginal increase in real-world performance.

Depends on "your real world" usage.
Still early in development at this time

We were really curious to see what performance gains can be enjoyed when using a blazing-fast PCI-Express 4.0 NVMe SSD, so we ran extensive tests using actual real-life applications, not just synthetic benchmarks that don't take into account how applications work today.
While the synthetic numbers are truly impressive for PCI-Express 4.0, showing over 5 GB/s actual transfer rates, which is 43% faster than the same SSD running at PCI-Express 3.0, the actual real-life gains are small.
Averaged across our test suite, we only see a 1% improvement, nothing you'd ever notice in real-life.

I'm interested in it not for SSD stuff but for improved bandwidth CPU<->GPU.

Presently only AMD/ATI cards support the new 4.0 version
Guess we have to wait for the next version of NVidia cards.
I believe that theoretically it should double the bandwidth

I was going to avoid replying and just let it die, but I read the page you linked to and I have to say... you gotta be kidding.
Installing Itunes is part of the test "real life suite"
I am sorry but how many times does anybody installs that. Personally its zero for me
The ADATA is given as 1TB but the other drive is a 2TB size so are we comparing scan times on what.
Like I said its still early but reviews like that are iffy, installing ITunes is a real life app? Because we do that twice a day.

Zero for me too. :P
