I wrote this a while back comparing Intel 12th Gen to AMD 6000, and power/perf should apply even more to the 13th Gen vs 7040 (Zen4 + RDNA3):
The reason that people want AMD CPUs is simple - they’re much better than what Intel is offering. We can see empirically how wide this gap is now since we have independent reviews of identical laptop platforms from Lenovo and HP’s ultrathin business laptops (the same segment as Framework):
HP EliteBook 840 G9 1280P vs HP EliteBook 845 G9 6950HS [1] - these are both respective flagship parts, and we can see the AMD version has both a +23% performance rating and a +23% better battery runtime. Note, that on the HP website currently, the same configuration AMD version is also >30% cheaper.
Lenovo ThinkPad T14s G3 6850U vs 1235U [2] - since the Intel version reviewed isn’t a top of the line model, it’s not fair to compare performance numbers, but even with the significantly lower TDP Intel part (15W vs 28W), the AMD version of the laptop ends up with an even bigger lead with a 35% better battery runtime. The AMD version is also 10% cheaper than their Intel counterparts from the Lenovo site pricing.
In both these cases, the AMD version wins significantly on processing power, battery efficiency and price. The 7040 should extend the lead on the latter, and that's not taking GPU performance into account [3], where the AMD Radeon 680M simply crushes the Intel Xe 96EU by an average of +88% in game performance, and +135% in synthetics (and again, the 7040’s RDNA3 GPU and Xilinx AI core will extend the lead even more for the upcoming generation).
Well, I have USB3 problems with all my AMD machines which makes e.g. attaching a VR headset reliably difficult. Random quickly repeated disconnects of devices due to a buggy chip from ASMedia/ASUS that AMD uses everywhere. I like TDP of the current gen though AMD turned to an even worse company than Intel in how it treats Threadripper users. DisplayPort over USB-C might not work either.
While having hardware compatibility issues suck, I'm not sure what your problems have to do with AMD's mobile APUs, which have their USB2/3/4 controllers implemented on-die (block diagram: https://cdn.videocardz.com/1/2021/12/AMD-Rembrandt-Diagram.j...) not using an external controller.
USB features depend ultimately on the laptop manufacturers' implementation (eg neither the HP or Lenovo models linked implement USB4 but they are in other models like the Lenovo Z13), but I haven't seen any that claim to have DP-alt support not be able to support it. As the Framework will have USB4 (and DP-alt and PCIe encapsulation are mandated by Microsoft for Windows 11 compatibility), I don't think that's a real worry for anyone.
Glad to hear that! My 8-core AMD laptop from ASUS with 3080 is almost 2 years old now so things might have changed. My Threadripper still has USB issues and I don't like e.g. inability to type text or move mouse for 10-20 seconds just because the USB controller on the most expensive Threadripper board decides to have a game of disconnects.
Again, I agree that hardware compatibility issues suck... Personally, I think life's too short to live with glitches like that - ASMedia chips are used in a lot of PCIe USB cards these days as well, but I've had good luck w/ Renasas cards in the recent past (when I was running VFIO). These USB cards are all pretty cheap ($20-40), so I'd order a few to try and keep the one that works the best.
