AMD ahead NVIDIA:  The first one to support PCIe 5.0

For a long time, we have always believed that both the NVIDIA Ada RTX 40 series and the AMD RDNA3 RX 7000 series will support PCIe 5.0, especially the data center-level Hopper H100 core has been supported, and the RTX 3090 Ti is also the first to support the PCIe 5.0 power supply standard.

However, there is information that the NVIDIA RTX 40 series still only supports PCIe 4.0 for unknown reasons.


What about AMD here? According to a reliable exposure expert @Kepler_L2, the AMD Navi 31 core is basically sure to support PCIe 5.0, and it will be called RX 7900 XT unsurprisingly.

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

On the other hand, AMD Zen4-based Ryzen 7000 series processors have been confirmed to support PCIe 5.0 , and the data center platform consisting of the next-generation Snapdragon 7004 processor and Instinct MI300 accelerator card will naturally not be absent.

 

As a result, AMD will have a complete PCIe 5.0 portfolio that can better unlock its performance potential.

 

The bandwidth of PCIe 5.0 is doubled again, the original data transfer rate reaches 32GT/s, and the bandwidth of PCIe x16 is as high as 128GB/s .

Naturally, high-end SSDs and high-performance computing fields can best reflect its advantages .

Consumer-grade game cards are not really useful.

 

PCIe 6.0 has also been born at the beginning of this year, and the bandwidth continues to double.

PCIe x16 can bring 256GB/s, and the PAM4 pulse amplitude modulation signaling, FEC forward error correction mechanism, and FLIT flow control unit coding have been upgraded, which is the biggest change in history.
