Apparently with the Ryzen processor, the slots are limited: "The Framework Laptop 13 with Ryzen™ 7040 Series processors has two fully capable USB4 ports, with the back left and back right Expansion Cards slots. The front left Expansion Card slot can handle both USB 3.2 and DisplayPort Alt Mode, while the front right Expansion Card can use USB 3.2. This does mean there is one Expansion Card slot that can't support the HDMI or DisplayPort Expansion Cards, and most OS's will provide a warning if you forget. You can charge your Framework Laptop through any of the four Expansion Cards as well.".

This is borderline a deal breaker for me.

[maztaim]

What are you expecting to run off all four slots that makes that a dealbreaker?

[mixmastamyk]

The whole point of the slots is to be able to rearrange them. If such options are limited, they may as well be standard ports, which would use less space.

It basically negates a significant portion of the utility of the device.

[mft_]

I’d always thought the point of the slots was to provide choice to each user to match their preference, probably at the time of the initial purchase.

Honestly, that one might want to regularly rearrange the ports hadn’t occurred to me.

[MichaelZuo]

It sounds like half the slots can't match the preferences of a substantial fraction of potential users?

[avargas]

This. Exactly this.

Expect the unexpected. It doesn't have to be a rational known ask. We are Hackers. We want to be ready for whatever. That day when there's a 4 screen display wall? Ready. Connecting to a thunderbolt NAS, a display, a desktop, and our friends laptop? Ready.

"What is the use case" is the deadening soul sucking most un Hackerly thing to ask. Computers are amazing general purpose machines & we celebrate their flexible utility. We don't know where flexibility always leads but we value it. We value open systems, open possibilities, open frontiers, not being bounded.

Edit: based on the voting, I guess only some of us on HN are Hackers! I also have example use cases too, to be constructive, but guess that's not enough for the cynics.

[ior4uiofrjnev]

A "hacker" is someone who makes something do what it wasn't intended to do. Plugging a high-end laptop into the correct number of monitors is not hacking.

Maybe stick to Intel chipsets if you must have 4 screens. Or maybe cover over the 4th port, and pretend you have 3 fully-functional ports?

[rektide]

That's a pretty good definition. It think there's more an element of being able to pull off the not forseen. A good code hacker isn't exactly defying computer architecture to extract their wins; they're finding brilliant solutions & cobbling together interesting systems that happen to meet the needs.

I think AMD needs the pressure. 4x Thunderbolt 4 is amazing. AMD offering 2x USB 4 is such a massive downgrade. Just a shake of the head & saying "go buy Intel" as if this is some natural expected unnoteworthy situation doesn't cut it for me.

[tracker1]

IIRC, USB4 Full is pretty much TB3 plus some extensions... So probably shouldn't really be a deal breaker. You can still use a TB dock and an eGPU. USB4 can support 20-40gbps, TB3 is 16, and TB4 is 36.

[0x457]

Not quite. USB4 is based on TB3, but interoperability with Thunderbolt 3 is optional for hosts and devices. You could use any TB4 dock and USB4 dock that have USB4 upstream ports.

40gbps, 20 gbps (in 3.2 mode), PCI-E are all optional for host.

It's a mess, but I assume "fully capable USB4 ports" means that they are indeed fully capable. 2 "full" USB4 ports imo enough. I'm not plugging 4 monitors into my laptop directly, that's what the dock is for.

[vidarh]

Any reason why you can't hook up that 4 screen display wall and that NAS at the same time by chaining DisplayPort and/or using a USB4 hub?

To me, being hackers means finding ways of circumventing limits, rather than expecting all kinds of connectivity to just be handed to you the easiest possible way.

What's attracting downvotes is more likely to be gatekeeping language like this.

[rektide]

I wasn't being super fair nor nice, but I very much felt like I was trying to combat gatekeeping. I was advocating for open & possible, against someone who was trying to shut people down.

Intel has 160 Gbps of throughput available for connectivity. You might be able to physically get data to all the same devices with AMD, but at much reduced bandwidth, and the job wont be as easy. And you won't be able to use thunderbolt peripherals like external GPUs, if those are available.

[ac29]

> And you won't be able to use thunderbolt peripherals like external GPUs, if those are available.

USB4 is Thunderbolt and the article explicitly mentions eGPUs work.

[rektide]

USB4 definitely does not require PCIe transport. (it does however require DisplayPort.) Once you have usb4 though, yeah, adding PCIe shouldn't be that much more work-you've already done the hard stuff. Which is part of why I've felt so cheated, thinking AMD hasn't done PCIe in their usb4.

This is, if true, very good news.

[maztaim]

There was no intention of gatekeeping. I was truly curious why someone would see that configuration as a deal-breaker.

[vorpalhex]

....then get the Intel processor?

Your external GPU may support USB4. Will depend on the enclosure.

[komali2]

What alternative laptop do you have in mind for running a 4 screen display, that's also hackable?

[JasonFruit]

"Why?" is a very properly hackerly question.

[rektide]

Agreed. Generally best used against systems & plans. Wanting to know how something ticks.

Using it as a cudgel against open frontiers happens too. I guess it's more a disposition of the person here. Personally I find that stark conservatism to be heinously ugly.

What is sometimes a very fine question, especially if someone is struggling to get to success. Recognizing the other cases though, where there are unknowns & where we want to have Postel'lian possibilities, where we want many small pieces we can loosely couple, where we aren't just trying to make it through right now but are trying to work for longer answers... I think the "What is the use case" is often a complete rejection of open thinking, is the mind closing.

[TOMDM]

That's pretty rough, one of the great things about the Framework was being able to treat all ports the same.

Is there any explenation on why they couldn't achieve this with AMD's new chips?

I'm sure they would have supported that if they were able to.

[mfer]

It has to do with what the chips can support.

Compare the AMD USB channels [1] with the Intel Thunderbold channels [2]. Intel has more channels for motherboard/system manufacturers to work with.

[rektide]

It's such a pity AMD revolutionized bandwidth & interconnectivity on Epyc (128 lanes PCIe) , but has left consumers hanging. Threadripper HDET was 64 lanes (the Pro really was a full Epyc, 128 lanes, 8 channel memory) but now Threadripper is gone.

Meanwhile desktop & mobile have been so capped, at 20 - 24 lanes, right where we were.

The Thunderbolt 4 abilities of Intel chips is just stunning. 160Gbps of connectivity, usable for host to host connectivity... I wish AMD were trying to catch up here, wouldnt compromise their lead by being so far behind here.

[dathinab]

it sounds bad

but it's pretty common in any multi USB-C port laptop

and most times the intuitive port usage will anyway be the right one

Like most external devices don't benefit in a notivable degree from USB-4 over USB-3.2. The most common exceptions are expanders, docks, monitors with integrated docks, eGPUs and similar.

But most of the you would normally anyway prefer on the back ports to get the cables out of the way.

Where the front ports are more often used for input devices, usb disks and similar. But they very very often yield the same practical performance on USB-3.2 and USB-4 (not always, but _really_ often).

So yes for some people which want 4 USB-4 port or 2 USB-4 ports and a HDMI port and a charging port and are not okay with the charging cable being on the front right port.

But the huge majority of people will not care.

And there are limitations with what the different laptop CPUs can support so it's not that they could just have magically added additional USB-4 ports or give DP support to all ports.
