The AMD Ryzen 5000-series processors are certainly among the best CPUs currently available, but one thing it lacks is support for external graphics cards via Thunderbolt 3 and USB 4 ports. However, it looks like AMD is planning to include USB 4 with eGPU support on its upcoming Ryzen 6000 processors.
The proof of this lies in the drivers presented by AMD engineers. A new Linux kernel driver patch has been introduced for Penguin OS. This patch includes USB 4 DisplayPort 1.4 tunneling, which is an essential feature of USB 4. As the patch is intended for Yellow Carp, it is likely that it is intended for AMD Ryzen 6000 processors, as this is the code name used for AMD Ryzen 6000. Rembrandt Processor on Linux.
It’s important to note that eGPUs are connected via a Thunderbolt 3 port, and this technology is currently only available on Intel-based systems. AMD CPUs do support USB 3.1, but it doesn’t work with most of the best external graphics cards. Although some users may find a workaround, they are not recommended, as the bandwidth and latency provided by that technology will not be sufficient.
Fortunately, Thunderbolt 3 is no longer exclusive to Intel users. USB 4 includes support for TB3, thereby opening up the technology to a wider audience. On the other hand, since AMD processors are not yet compatible with USB 4, Ryzen users still had no way of using an external GPU. It looks like things may soon change for AMD fans if the new evidence turns out to be true.
The option to use an external graphics card is a welcome feature for notebook users, bringing the laptop’s gaming capabilities to the next level. As graphics cards are often bulky, it is difficult to fit them inside the thin, portable laptops that are common in the market nowadays. This leads manufacturers to compromise on graphics quality, leaving gamers frustrated with low frame rates.
Although AMD Ryzen processors have taken the processor market by storm in recent years, Intel continues to drive the majority of CPU sales. This is unlikely to change in 2021, as Intel is also outpacing AMD in launching the next generation of processors. Intel Elder Lake is rumored to be released in early November 2021.
The next generation of AMD processors, the Zen 4, is confirmed to be released in 2022. While no official date has been revealed, there is speculation from AMD to drop the new CPU at the beginning of the year.
