For a long time, we have always believed that both NVIDIA ADA RTX 40 series and AMD rdna3 RX 7000 series will support PCIe 5.0, especially the hopper H100 core at the data center level. RTX 3090 Ti also took the lead in supporting the PCIe 5.0 power supply standard. However, information shows that NVIDIA RTX 40 series still only supports PCIe 4.0 for unknown reasons.

What about AMD? According to a reliable exposure expert @ Kepler_ L2, amd Navi 31 core is basically determined to support PCIe 5.0, and it will be called RX 7900 XT**

He did not disclose where he got the news, but recently, amd began to frequently add the information of Navi 3x series core in Linux kernel patches, which should be a clue.

On the other hand, the Ruilong 7000 series processor of AMD zen4 architecture has confirmed that it will support PCIe 5.0 . Naturally, the data center platform composed of the next generation Xiaolong 7004 processor and the insight mi300 accelerator card will not be absent.

In this way, AMD will have a complete PCIe 5.0 product portfolio, which can better release its performance potential.

The bandwidth of PCIe 5.0 has doubled again, and the original data transmission rate has reached 32gt / s, the bandwidth of PCIe x16 is up to 128GB / s . Naturally, the high-end < a data link = "1" href = "" target = "_blank" > SSD < / a > and high-performance computing fields can best reflect its advantages. Consumer game cards are not very practical.

PCIe 6.0 was also born at the beginning of this year, and the bandwidth continues to double. PCIe x16 can bring 256gb / s. In addition, it has upgraded pam4 pulse amplitude modulation signaling, FEC forward error correction mechanism and flit flow control unit coding, which is the biggest change in history.
