PCI-E 4.0 SSD tested - slower than 3.0

[cucker tarlson]

seems like with the exception of synthetic scores the drives are performing much better on intel's pci-e 3.0
if you take a look at small file copy,multitasking (simultaneous copy+install) and installation times, the same drive is 15% faster on intel's 3.0 than ryzen's 4.0
LINK TO FULL REVIEW

damn that mp600 is fast though.

Or maybe single-threaded performance is the bottleneck and not the drive? Installation could be doing a lot more than just copying data. For example, the installation data might be compressed, in which case you're testing the decompression algorithm more than I/O. They needed other 3.0 devices tested on the same AMD platform in order to come to the conclusion that PCIe 4.0 is actually slower (which it's not, it's far more likely that latency is the problem, which would be apparent on PCIe 3.0 devices as well,) when that's contradicted by the synthetic benchmarks which are designed to specifically only test I/O.

PCI-Express 4.0 NVMe SSD Performance on Ryzen 3000 & X570

AMD's new Ryzens are the first desktop processors to support PCI-Express 4.0, which doubles transfer rates over PCIe 3.0. We test real-life performance gains using the 2 TB Gigabyte Aorus Gen4 M.2 NVMe SSD, which reaches over 5 GB/s in sequential speeds.

3. Keep in mind that the Phison E16 controller is a PCIe 3.0 controller strapped to a PCIe 4.0 bus, it's not a good representation of what PCIe 4.0 SSDs will be capable of.

sorry,but no one except ppc tested intel's 3.0 vs amd's 4.0
neither the link you provided

well not for file copy probably.
and doesn't amd boast highest ipc ?

btw this is pretty much in line with what ryzen 1000 showed

AMD Ryzen SSD Storage Performance Preview

We provide an early look at AMD Ryzen SSD storage performance versus Intel in a range of different early tests.

so no improvement for 3 generations despite the 4.0 feature

yas!

Well it depends on test methods - I had a much higher score on my old Z170 based system than my x570, but In real life I am pretty sure that they score of my x570 is the more realistic one.

Above from my Skylake Z170 setup

Same disk on my x570 setup

So its not easy to compare these benchmark

 

[cucker tarlson]

lol that is not possible to have 8000mb/s sequential read and 250mb/s 4k random read.
btw the review is comparing z370 and 8700k,I think older gens (kay and older) were much more heavily impacted by smeltdown patches.On my 5775c/z97 4k write dropped from 110mb/s to just 85mb/s (-23%) after the patch,disabled it's back to normal.That's probably why TPU shows sx8200 running on 7700k at 93% performance of ryzen.Wonder why test Kaby.

The dude is using caching for those results, lol.

It is, if you notice you've actually ramcached the drive on Z170.

My rapid mode and Asus ramcache where actually attached to my two SATA SSD drives so thats not it - but for some strange reason the score with both my Samsung EVO 960 and the Corsair MP600 where high. So there must be some other windows/intel caching that helped the score. The point being that its is dificult to compare these benchmarks across different platforms

no,the higher number wins.
