Intel needs AMD CPUs in order to test their future PCIe 4.0 SSDs
Oh, how the tables have turned -- Intel has no CPUs that are capable of supporting PCIe 4.0 technology, so they need to use AMD Ryzen 3000 series CPUs along with an X570 motherboard to test their latest storage products.

@axboe Is there a minimal kernel version you recommend for using liburing ? I see a lot of tests failing when running make runtests, and one of them fails in a way similar to some weird behavior I was trying to chase down in the code I am writing. I'm on 5.3 (because lazy)

@glcst would you like to test on gen2 pcie 4 capable optane ssd to see your code's potential? Then I can set that up for you. Send me a private email when you are ready... @axboe has his own...
Intel technical marketing performance engineer, Frank Ober, tweeted (above) that Intel can send PCIe 4.0-capable SSDs to developers, but they'll need PCIe 4.0-capable CPUs and motherboards to test them. The super-fast new Alder Stream SSDs (an updated version of their Optane drive tech, with second-gen 3D XPoint technology).
But in order to ramp up those speeds they will need more PCIe lanes, and since PCIe 3.0 is pretty much tapped out -- the doubling in bandwidth to PCIe 4.0 is a tasty offering. But, Intel has no PCIe 4.0 anything right now -- so they're stuck. Intel won't have PCIe 4.0-capable CPUs until 2021 which means they need to lean on their main competitor in AMD until then.
