[QUOTE="MacDefender, post: 927029, member: 83059"] For newer generation devices, absolutely RAM is faster. I was more talking about mid-2000's CPU to RAM bandwidth, [URL='https://www.anandtech.com/show/2061/4']Memory Performance - Intel Core 2 Duo: Memory Performance Part Deux (anandtech.com)[/URL] It wasn't that long ago when CPUs can barely push 3GB/s of memory to memory performance, though yeah today RAM is much faster than NVMe and with more and more of the move towards integrated memory controllers, real world CPU to RAM performance has gotten a lot better too. Note too that NVMe based SSDs with SR-IOV are right around the corner: [URL='https://www.servethehome.com/samsung-pm1733-pm1735-pcie-gen4-ssds/']Samsung PM1733 and PM1735 PCIe Gen4 SSDs | ServeTheHome[/URL] SR-IOV will be a huge step up in performance, as it basically moves the virtualization onto the SSD and the SSD provides to the VM what looks like a native SSD. So there will be zero IO overhead from a VM, and the host isn't involved at all. And that one is rated for 8000MB/s read performance.... [/QUOTE]
