Phoronix: AMD Prepares Linux Driver Support For USB4 DP Tunneling

The newest patch series by AMD open-source Linux graphics driver engineers worth mentioning is around USB4 DisplayPort tunneling support for next-generation AMD hardware supporting USB4 connectivity...

DP Tunneling huh?

I am looking forward to USB4. Finally it will be possible to get an affordable hexacore laptop with an energy efficient AMD CPU that lets one connect an eGPU and use it for gaming aswell.

Apparently, DisplayPort tunneling/alt mode is mandatory for USB4 ports.

I am looking forward to USB4.

Meh, pass. We're supposed to get DDR5 and PCIe5 next year. The PS5 console is available now. Gen4 technology is basically EOL. I'm holding out for USB5.

It looks like AMD is **forcing** me to wait for 6000 series APUs next year. I really needed to upgrade my laptop now but availability is scarse and the number of options is well... just one. Apart from the Lenovo ThinkBook 14p Gen 2 I cannot find a single lightweight laptop with a Ryzen 5800H, at least 32GB of ram (it was originally planned, but it looks like they changed their mind for the 14p), no useless Nvidia bricks inside and a monitor which doesn't require floating point scaling (even the 14p doesn't check this mark unless it's the 2.8K OLED one). I would **love** to have USB4, but I would love even more to be able to change my development laptop now. Maybe by the time 6000 APUs get released even Dell will decide to abandon Intel for their XPS 15/17. Unfortunately I'm pretty sure they will stick an useless Nvidia graphics card inside as well

Intel will hit back hard with Alder Lake mobile. They aren't going anywhere.

AMD's high-end, higher TDP mobile APUs are practically intended to be paired with graphics cards. It's no surprise if most of the 5800H models have a discrete GPU inside.

Ryzen 6000 APUs should be worth the wait. Since they could nearly double iGPU performance, maybe there will be more of them without discrete GPUs.

torsionbar28 Thunderbolt5/USB5 will be equal to PCIe 4.0 in terms of bandwidth per lane. Also, I wouldn't bet on the first mobile DDR5 designs to be significantly better than current LPDDR4X or DDR4 (in terms of latency, it's going to be worse; used to be the same when DDR2, DDR3 and DDR4 launched). PCIe 5.0 is nice for storage, but other devices like GPUs barely even manage to utilize 3.0 x16.

If people wait to buy a new system based on emerging technologies, they will wait forever, because there always be a new gimmick in the near future.

Also, being too nitpicky on what you pretend to buy will put you in the corner with no way out. Just avoid what bother you more and forgive the rest, there is no perfect machine. There always be something you would change if you could.

I hope so, but I wouldn't bet on that.

I'm a software developer, I need a fast multi core CPU to compile but I don't care about graphics.

Ryzen 6000 APUs should be worth the wait. Since they could nearly double iGPU performance, maybe there will be more of them without discrete GPUs.

I hope so, not because I need the performance but because I don't won't to carry the dead weight of a Nvidia brick (and I also I would hate to give them any amount of money).
