Haben Sie Fragen zu Bandbreitenbeschränkungen?
You have multiple NVMe drives and a high-end GPU setup. Installing both M.2 drives might affect performance, but it depends on how your system manages resources. Consider checking your current bandwidth usage and ensure enough space and configuration for smooth operation.
Technically they might overlap in bandwidth, but in practice it's improbable you'd need to maximize both the NVMe storage and GPU usage simultaneously. I've never noticed my RTX 2080 consuming half the PCIe lane, and the storage only reaches peak performance briefly. It probably isn't something you'd really observe.
It won't happen; the two M.2 drives along with other components like the SATA SSD will vie for bandwidth since they're all linked through the chipset. They share the DMI 3 connection to the CPU, which functions similarly to a PCIe 3.0 x4 interface in terms of data transfer capacity.
Ryzen supports four lanes for M.2 SSDs, eight lanes for GPUs when using APUs, and four lanes for the chipset. Some boards such as the Asus B450-I reduce GPU bandwidth to free up an additional M.2 slot, resulting in a combined total of two slots. This configuration isn't standard.
It's clear that many forum members had mixed views, with some believing M.2 slots shared the same PCIe port as the original slot.
On the Z390-E, comparing these setups depends on your needs. The 970 Pro NVMe with 500GB and M.2 3.0 offers faster speeds, while the 970 Pro NVMe with 970 EVO provides a more affordable option. Which suits you better will depend on performance requirements and budget.
