Nope that’s more like cache write speed. Single-threaded sequential access to RAM is typically more like 10-15GB/s for current server CPUs: https://panthema.net

- Retric 8y agoRAM is not nessisarily single threaded. Unganged Dual / quad channel memory is effectively multithreaded. So really his numbers are real world even with CPU bottlenecks. https://www.techspot.com/news/62129-ddr3-vs-ddr4-raw-bandwidth-numbers.html https://www.techspot.com/news/62129-ddr3-vs-ddr4-raw-bandwid... PS: DDR4-3200W in quad channel mode is crazy fast and should break 100GB/s though sill a long way from a 1080Ti 484 GB/s.
