are speeds of bleeding edge mem devices getting close to RAM?
- Scene_Cast2 4y agoIn terms of bandwidth or latency? All conditions, worst case, best case?
- cogman10 4y agoNot really. Max throughput is around 6gbps with a fairly high latency. DDR5 has speeds of 52gbps, lower latency, AND your CPU will almost undoubtedly have a cache on it to increase that speed further. This is all assuming you are putting your mem device on a pci-express bus.
- KennyBlanken 4y ago> Max throughput is around 6gbps with a fairly high latency. In the consumer market, a number of performance NVMe drives will hit over 5GB/sec, which would be 40 Gbps. The latency isn't anywhere near as good as even quite-old RAM, but modern SSDs are considerably less than an order magnitude off in transfer speed from even current, common ram (DDR4) and "only" about a hundred times higher in latency than RAM. That's pretty stunning from mass storage. So is well over 500,000 IOPS.
