Although AMD's Ryzen series processors have achieved performance suppression over the same period of Core processors, the Ryzen platform still has regrets in terms of functions-there is no independent AI processing unit, and it does not support the emperor. lightning interface .
Among them, the Thunderbolt interface is very important for notebooks.
We all know that notebooks are restricted by their size and cannot accommodate too many ports. It is inevitable to deal with various types of docking stations . The reason why Raiden is known as the "emperor" of the interface is because it has a transmission rate of up to 40Gbps, supports DP video transmission and PD charging protocol, and can connect to an external desktop graphics card docking station to transfer almost all interfaces.
Intel has integrated the Thunderbolt controller in the CPU since the 10th generation Core, which greatly reduces the physical cost of supporting this interface. By the time of the 11th-generation Core, many 4,000-yuan notebooks were equipped with Thunderbolt 4 as standard. By next year’s 12th-generation Core era, the Thunderbolt interface is expected to be further popularized on the Intel platform.
Although Intel also sells JHL series Thunderbolt controllers, in theory AMD platform motherboards can also support Thunderbolt functions, but AMD motherboards that support Thunderbolt are extremely rare so far. Obviously AMD is a partner of AMD I am also reluctant to advertise for Intel.
With the release of AMD’s next-generation Ryzen 6000 platform,AMD has finally obtained the qualification to compete on the same stage with Intel.
A few days ago, some netizens discovered that a new AMD GPU driver has appeared in the Linux kernel library, which adds support for USB4 to transmit DP 1.4 signals. Judging from the rhythm of Linux patches, Linux 5.16 is expected to add the AMD platform's official support for USB4 DP transmission. This also means that AMD's next-generation Ryzen 6000 platform is likely to natively support the full-featured USB4 interface.
Many people say that USB4 is the vest of Thunderbolt 3, but in fact this statement is not accurate.
To put it simply, USB4, like Thunder 3/4, adopts the USB Type-C interface form, but it is more like an enhancement and expansion of the "full-featured USB Type-C".
USB4 functions include mandatory and optional options.
All USB4 must support DisplayPort 2.0 video transmission and Power Delivery (USB PD) charging protocol (up to 100W), which is already achieved by the existing full-featured USB Type-C.
However, the optional functions of USB4 are more abundant. It supports 20Gbps transmission speed from the beginning (equivalent to USB3.2 Gen2×2 and half-speed lightning),The highest transmission speed can be 40Gbps, which is equivalent to the existing full-speed Thunderbolt interface.
According to different speeds, USB4 can be subdivided into USB4 20 and USB4 40. If you are pursuing faster speed, obviously you have to look for the following standards.
In addition, USB4 can also be optional compatible with Thunderbolt 3, note that this is also an optional feature. The USB4 interface compatible with Thunderbolt 3 function can also be compatible with the existing desktop graphics docking station, allowing the notebook to instantly gain stronger gaming power.
Therefore, even if the notebook equipped with AMD Ryzen 6000 platform is equipped with USB4, it will also derive three specifications of USB4 20 and USB4 40, full blood USB4 (compatible with Thunderbolt 3). Only a notebook that is really equipped with a full-blooded USB4 can have the confidence to challenge the thunder and lightning 3/4 of the next door.
As ordinary consumers, we certainly hope that all USB4s are full of blood, but this is only our wishful thinking.
