I thought this line was interesting:

> with no externally visible fasteners

I wonder if it was easier or thinner to do that way, or if it was a deliberate design choice for a more minimal appearance.

Personally I don't mind seeing fasteners. After swapping LCDs on my old Thinkpads a couple times, I stopped replacing the screw covers and embraced one fewer step for future maintenance.

Amazingly enough, we didn't go in with this as a design goal from the start. The Framework Laptop 13 has exposed fasteners on the Bottom Cover, and we went in assuming we'd go the same direction. As we designed the Input Module system, it became clear that the best way to design it was installing everything directly down into the Bottom Cover, meaning you don't need to flip the system over to unscrew anything. The result is a Bottom Cover that is super clean.

Sorry for the stupid question, what is the advantage of your new connection for gpu? why not oculink or pcie riser or thunderbolt?

PCIe is too physically large, Oculink is too thick and doesn't have enough pins for power, and Thunderbolt has protocol overhead and throughput limitations.

It seems to me that oculink port is still a good option for side module, although it's unrealistic. I hope ltt lab create custom gpu module from the desktop 4090: built-in power, water cooling and of course rgb :)

Yeah, sorry, no. Thunderbolt does have overhead and limitations, but imo those limitations don't justify making a new standard, even if it's more open than the others. Maybe you could say more about those limitations and convince me?

What obligation do they have to convince you?

None. Just like my obligation to buy one.

For instance, Thunderbolt bandwidth is limited to 40 Gbit/s. The Framework adapter for GPU is PCIE x8, which gives 128 Gbit/s.

(not affiliated with the Framework company, only as a owner of two 13" Framework laptops; so I might be wrong/incomplete about the limitations implied by the OP)

There are companies putting nonstandard PCIe ports on the outsides of laptops, and compared to that an internal custom port is much less egregious. 40Gbps is just not enough to run a GPU without significant performance loss. Especially when 40Gbps is actually 32Gbps of PCIe and on older controllers there's an arbitrary limit of 22Gbps.

I really hope thunderbolt 5 in asymmetrical mode can devote the entire 120Gbps of outgoing data to PCIe, and doesn't have some stupid limit like 64Gbps.

And when a new standard amounts to "arrange the pins like this", it's not a very big deal.

Lots of lenovos, MSIs were using the "bathtub" back in late 200X.

But when the trend for ridiculously thin laptops came, they went back to upside down.

Visible fasteners are actually a plus for me - they are a signal that the device has a sane, maintainable design!

My Macbook has visible fasteners and it doesn’t have a sane, maintainable design.
