New NVMe drives claim 5GB/s on PCIe 4, is memory mapping something like that not good enough for you already?

- fulafel 7y agoIn these applications you primarily care about latency. Even these new SSD's have latencies 3 orders of magniture higher than DRAM. The 20 usecs is access time is about 100k executed instructions (scalar + single thread).
- BubRoss 7y agoIn what applications? The parent didn't even say what they were working on. Everyone wants ideally wants a perfect memory technology with no latency, large sizes and persistence, so I'm not sure what you are talking about exactly. If something needs less latency, you cache it or load it into memory. You seem to be saying that this current technology, that actually exists, is not good enough for a mystery application because it isn't as good as theoretical memresistors.
