x32 and beyond are very common in ultra high end modular servers. If you look at the server manufacturer Trenton Systems, they have massive PCI-E array capability.

[@shanent5793]

@@sakaraist If they were referring to the total number of lanes, then this wouldn't be noteworthy because RYZEN Threadripper consumer boards have had more than 32 lanes for several years already, but they're never referred to as PCIe x32 devices. Riser cards are just glue, not end devices and are out of scope. In the case of NICs, they may have two x16 ports that can be connected to different sockets in a system to save inter-socket bandwidth, but PCIe will still treat them as two separate devices. FPGAs could of course be programmed to implement PCIe x32, but if you want to use the hardened PCIe IP it will still be x16. If your devices have actually negotiated a PCIe x32 link at the hardware level, I would love to know the part numbers because even PCI-SIG doesn't know about them and they're definitely not off-the-shelf

[@jnharton]

@@shanent5793This needs more upvotes, honestly. ----- Just because the slot can carry 32 lanes doesn't mean that there are must be any true 32 lane devices. Makes perfect sense that you might make a single board that is a carrier for more thin one device and use a single slot. Especially in an industrial context where one larger slot might be better than a bunch of extra slots and little cards everywhere. Kind of a throwback to the days of large card edge connectors for parallel buses, only using each signal line as a separate communications lane.

[@eliadbu]

@@TheHammerGuy94 In SLI, the PCI_E is used to communicate with both devices at the same time as they both work in unison to render interlacing frames, this is more like having a second card its whole purpose is to pass the communication to the main card, so it is not as RAID 0 - as with RAID 0 both devices are part of an array and are the same.

[@Arctic_silverstreak]

Not really, just a fancy name of link aggregation for, mostly, network card

[@ManuFortis]

Kind of, but not really. It is using similar methods, but it's not exactly the same. This is probably closer to what is done on AMD's workstation cards with being able to attach a display synch module between multiple workstation gpu's to output as a single monitor signal with one of these: AMD FirePro™ S400 Sync Module for instance with AMD's workstation cards. (Nvidia has their own version, but I don't know the details.) If you look at the card shown by Riley in the video, you'll see that cable connecting them. I'm not sure of it's exact connector specs, but it will be somewhat similar in nature to the JU6001 connector that can be found on the AMD WX series cards. Sometimes it's populated with an actual socket/port. Sometimes not. Essentially, if I understand correctly, instead of each of the cards sharing the workload intended between them, they are all doing their own work, or shared work perhaps in some cases, and outputting it all to the same monitor. It's a subtle but important difference, because SLI/Crossfire typically is used for splitting workloads between GPU's to get a better end result, where as display synch (as I will call it for now), is more about combining separate or even shared workloads into a single tangible visual result. That sync card is effectively doing what Riley explained about the x32 setup, and the asynchronous data streams typical of PCI compared to when they are... well... synced. Maybe not the worlds best explanation, but I hope it helps.

Each time someone buys any current Intel 1700 and you add an ssd it gets bumped down to ×8 anyway leaving 4 of the very few lanes you have useless. AMD has the same thing, in practiced expect a card to always ×8. Then any bench you see where the compare ×8 to ×16 there is minimal to no difference unless you go down a generation. Just make GPU link on desktop ×8 by default and make room for 2 more NVMe slots.

⁠@@jamegumb7298AMD does not have the same thing Unless its a dogshit motherboard you can have 2X NVMe slots at full speed at the time and an X16 slot Its when you go past 2 you run into issues as your either adding multiple to the chipset or you start stealing lanes Without any performance loss on conflicts you can have these configurations in AM5 2x NVMe + 1 x16 4x NVMe + 1 x16

The cooling would be problematic, would need a 360mm radiator maybe a 420mm. Though I guess if you afford one the cooling and power costs wont matter ! Big problem with SLI is that memory is become a bottleneck. The two cards VRAM don't add together. So 2 X 24 is still just 24. So it would need like 2 x 48. Fuk that would be insanely expensive.

Just a thought 💭🤔.. if you want a super small SFF build the motherboard only has 1 PCI express slot usually plus some nvme slots. So if you have 1x 32x pci express slot you could have 1 card that has the GPU and SSDs and dedicated npu and a 10gb NIC ect all in 1 expansion card especially if you have 1 side of the PCB for the GPU and the other side for the npu and SSDs and NIC and all the other hardware you want. It would make for very capable SFF builds or very very tidy full size builds that only has the motherboard and CPU and cooler and ram and 1 expansion card that's a mix of all kinds of different hardware.. so as much as we don't need 32x PCI express lane's for general hardware but the idea and the 32x slot could definitely be used up..

[@chaosfenix]

I would like to see an update to the actual PCIE slot standard. It doesn't have to be exactly like this in that I don't care about the specifics like the connector type but I think I would like this architecture. It would be something like an MCIO connector that would only have 4 lanes by default. That is it. No more than that would be allowed in the connector. Each individual connector would be specced to provide power between 50-100W. I don't care the specific range. Just that it should be able to provide up to a specified power. You would still support pcie bifurcation which means you could then turn a 4 lane port into a 2x2, a 2x1x1, or a 1x1x1x1. This could be amazing for addin cards as if you wanted to add a bunch of PCIE devices you would simply assign a single pcie lane to them. Honestly not too much different here from the current spec. Here is where it would get spicy though. Part of the spec would be spacing between each individual MCIO connector. The reason for that is because you would also allow not only for the bifurcation of the slot but for the combination of the slots as well. Maybe the devices going greater than 4 would simply use Driver Binding like you said, I imagine it would be relatively easy to bind 2-4 4 lane pcie connections. Single mode would be the default but you could choose to combine up to 4 of the slots together as well in the bios. This would mean that you could still have devices connect to up to 16 PCIE lanes if you wanted but if you didn't then you would simply have 4 individual MCIO connectors you could direct attach to instead. It would be hugely more versatile. Also you would get your greater power delivery in that a more power hungry device using all 4 connectors would be supplied with like up to 200-400W of power directly. Sure you are going to have devices, especially GPUs, that still need additional power but that should be rare if they could work with up to 400W. I think you could even allow some backwards capability if you made available an adapter to go from the 4 MCIO connectors and PCIE. Then you would just need to provide cheap standoffs for the screws at the back. This wouldn't be a problem for most cards but if you had a chonker like a 4090 you could have z height issues in the case. For most regular cards it wouldn't be an issue though and the issue would go away eventually as people switched to the new standard.

The X is referred to as "by" though. So a PCIE x4 is called PCIE by 4 and so on

Thankyou. It's like when people refer to camera zoom eg. 4x as "4 ex". Infuriating

[@Vermicious]

@shall_we_kindly It’s a multiplication. Is 5 x 10 “five ex ten”?

[@TheMatthewDMerrill]

Yeah x4 and x8 used to be a lot too. In less than 10 years we'll be seeing more x32 things.
