Intel’s 12th generation Core has brought the first PCIe 5.0, but if you want to see PCIe 5.0 SSD and graphics card, you have to wait for a while. The improvement effect is definitely not as obvious as PCIe 4.0. Nowadays,MSI is the first to display the PCIe 5.0 SSD expansion card, named “M.2 Expander-Z”, Plug into the PCIe 5.0 expansion slot of the Z690 motherboard, you can then install multiple PCIe 5.0 SSDs, of course, you can also use PCIe 4.0 SSDs, and use active fans to enhance heat dissipation (can be turned off).
MSI declared,Its transmission bandwidth can be as high as 128GB/s.
However, the 12th generation Core only supports 16 PCIe 5.0, each with a bandwidth of 4GB/s, and all of them are 64GB/s. That is to say, MSI is either talking about two-way bandwidth or adding bridge expansion.
In addition, the Z690 motherboard does not support PCIe 5.0, so this expansion card can only borrow the bandwidth of the processor, which will inevitably affect the bandwidth of the graphics card. Of course, PCIe 4.0 x16 graphics cards can’t be eaten, and PCIe 5.0 x8 can still be more than enough.
As for PCIe 5.0 products,Phison and Meiman Electronics have disclosed the master control plan, but they have not yet released it.SamsungKioxia has shownSSD, But they are all enterprise-level and are expected to be released in the first half of next year.
In terms of graphics cards, it is expected that NVIDIA Ada Lovelace,AMDRDNA3 is expected to join, and the RTX 3090 Ti at the beginning of next year will be equipped with PCIe 5.0 16-pin power supply interface. I don’t know if PCIe 5.0 will also be turned on.
