In addition to upgrading the CPU and GPU core, AMD's Ruilong 6000 series processor also comprehensively improves the peripheral interface, fully supports the usbc4 interface comparable to lightning 4, and also supports the DP 2.0 video interface. Now it is the first batch of VESA's official DP 2.0 uhbr certification.
In fact, this certification has been obtained by three manufacturers. In addition to AMD, there are MediaTek and Ruiyu electronics. However, AMD's Ruilong 6000 is the only PC processor and one of the first DP 2.0 uhbr devices that ordinary players can buy.
After obtaining the DP uhbr certification, the DP 2.0 interface of Ruilong 6000 notebook can support various high bandwidth applications. One cable can realize uncompressed 8K 60Hz HDR, 4K 240Hz HDR, two 4K 120Hz HDR or four 4K 60Hz HDR display output, which is very powerful**
DP 2.0 specification was released as early as 2019. The theoretical bandwidth has been increased to 80gbps at one stroke, and the new coding mechanism 128 / 132b is adopted to improve the efficiency to 97%. The actual availability is as high as 77.4gbps, which is equivalent to three times of DP 1.3 / 1.4, far exceeding the theoretical bandwidth of HDMI 2.1 of 48Gbps.
As for the data line, DP 2.0 actually introduces three different mechanisms. The bandwidth of each channel is set at 10Gbps, 13.5gbps and 20gbps respectively. VESA calls it uhbr / ultra high bit rate, which is called uhbr 10, uhbr 13.5 and uhbr 20 according to the bandwidth.
The original bandwidth of uhbr 10 is 40Gbps and the effective bandwidth is 38.69gbps. Passive copper wire is enough. The previous DP 8K wire certification project actually includes it, that is, the DP data line passing 8K certification meets the signal integrity requirements of uhbr 10.
Uhbr 13.5 and uhbr 20 are different. The original bandwidth is 54gbps and 80gbps, and the effective bandwidth is 52.22gbps and 77.37gbps. Passive wire can only be used for very short-distance transmission, such as notebook docking station. If it is longer, active wire is required, that is, corresponding control and amplification chips are implanted
