It sounds like this splits the pcie lanes it provides into two, effectively halving bandwidth. Wouldn't this impact the performance of the GPU?

- ThatPlayer 3y agoThis looks to be using PCIe 5, which is 2x the bandwidth of PCIe 4. Considering a RTX 4090 is still using PCIe 4x16, so effectively the same bandwidth as PCIe 5x8, it should be fine.
- wtallis 3y agoThis solution allows the SSD to use PCIe gen5 speed, but does not include a full PCIe switch so PCIe gen4 x16 from the GPU cannot be repackaged into PCIe gen5 x8 for the trip up to the CPU. Which is why this is being introduced on a GPU that only does PCIe gen4 x8.
- ThatPlayer 3y agoYou're right. I didn't see that spec for the 4060.
- AdrianB1 3y agoNo, for 4060 and 4060 TI the GPU is linked to only 8 of the 16 PCIe lanes, the other 8 are not used. Asus is using 4 of these unused lanes.
- duskwuff 3y ago> Wouldn't this impact the performance of the GPU? It isn't a super high performance GPU to begin with, so the narrower bus is unlikely to make much of a difference.
