I'd love to be in the meetings for the PCI standards group: "Next version is due out soon, are we all agreed we double the speed as usual?"

[@portalwalker_]

PCIe naming is just the opposite of USB

[@jdbertel33]

In 2002 or so I job shadowed an engineer at intel for a couple days. Got to see a 10ghz Northwood ALU and sit on a call discussing the physical spec of pcie 1.0 with reps from like, dell, hp, asus, and others. Was wild.

[@dennisfahey2379]

Pretty much. The same in networking. The goal is 10X and often there is an intermediate 4X baby step. What's interesting is these internal expansion buses used to be parallel (ISA, EISA, VESA, PCI) but the PCI-E broke away and became more of a network topology. In fact the "rate determining" bit is a thing called a serial/deserializer or SERDES. And the ubiquitous and high volume PCI-E and Ethernet keep pushing that function to its next plateau. PAM4 started in the networking side of the game and once it was in the chip library slid - very naturally into the SDRAM and PCI-E functions. Datacenters drive the progression and CXL is going to be HUGE. It will liberate the dedicated coprocessor market. (GPU's were a dedicated coprocessor - many many more exist.)

[@timramich]

​@@dennisfahey2379NVMe is what is driving this progression. Why use 4 lanes for an SSD when you could use 1? Get into a high number of drives and you run out of lanes. Then you look into running multiple servers just to network out data to a main data controller server. This will bring things more in line with what SAS did. Multiple JBOD chassis worth of drives connected via PCIe to a single server without needing any kind of PLX type of thing.

[@scythelord]

Actually it would be more like "THREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE FOURFIVE S...SEVEN" PCIe4.0 hadn't released a single device before 5 was a finished standard which is kinda why intel opted to ignore 4.0 and wait the year or so to adopt 5.0.

It's primarily for data center use. They can use an x16 link over wire to interconnect to other blades in a rack.

[@peterwstacey]

Can't speak for AMD Chipsets, but for Intel this is already the case - DMI is effectively a PCIe-like interface that wraps PCIe, but also other formats like USB, SATA IDE, and even UART - basically all data from the PCH. This is why DMI is written as 4.0x4 - a similar nomenclature to PCIe

[@lucth16]

That creepy AI video @3:30

[@marcus_cole_2]

PCI Express 7.0 will likely be used for neural processing units (NPUs) on local computers, allowing users to buy specialty cards for that purpose. These NPUs will be at the top of the PCI Lane motherboard layout, with the GPU lane underneath. As AI and AGI continue to advance, people will want self-contained units for tasks ranging from video editing and overlaying to full-on Jarvis-like capabilities. Alternatively, PCI Express 7.0 might be dedicated to external boxes handling AI, AGI, and GPU units through fiber-optic or proprietary plugs. The average computer, with a GPU and basic NPU, currently takes up 4 to 5 card slots, making it challenging to utilize all PCIe slots efficiently.

[@bocahdongo7769]

Just add more lane, like you know, AM5 eventually did add. Much more easier, cheaper, and possible than pouring extra money to speed up the development for consumer grade and make consumer deal with the 100% extra price on top of already overpriced motherboard. If you concern dies are getting big, you can shove dual arm retention bracket that Xeon already used from 15 years ago.

[@gsestream]

at those speeds, you dont need separate memory interfaces, pci-e 7 is the memory interface. I remembet that rtx 4000 series memory bandwidth is something like 500GB/s. bit or bytes, make it clear. B can be bits or bytes. small or large.

Optics has huge latency, so it can be justified only on distances higher than 100m (0.1km). The only option that may work is transmission line for electromagnetics waves implemented like some kind of coaxial cable on PCB (one transmission line per copper wire on PCB).

[@brandonedwards7166]

Another use case for PCIe 7.0 is that you can use less lanes with the same amount of traffic. A lot of PC have limited PCIe lanes. So having more lanes available is a plus. PCIe 4.0 16x = PCIe 5.0 8x = PCIe 6.0 4x = PCIe 7.0 = 2x

[@TatsuZZmage]

Isn't that what the swap file is slow ram?

[@myne00]

Ram cards have existed on and off several times. Last onei heard of was in the ddr2 era

[@SuperSmashDolls]

In order for any component to be usable as RAM in a system, it needs to be on a system bus that can answer memory requests, and that bus needs to operate at very high speeds. Modern CPUs don't have a single generic system bus for both external hardware and memory devices; instead they have PCIe, DDR, and other pinouts. Only the DDR bus will actually show up to software as RAM. Other storage devices are incompatible; not only are they too slow, but they also work with data at the wrong size. e.g. DDR5 is two 32-bit data channels, but hard drives work with data in 4096-byte chunks that have to be read or written all at once. Swapfiles are how you get around this limitation, by having OS code manually juggle data between slow storage devices and fast memory devices that the CPU can natively access.

[@RepChris]

@@TatsuZZmage the swap file, as the name suggests, is a file, not actual RAM. Its used to swap out sections of RAM with memory on the disk if your tasks need more RAM than you actually have. It doenst have the "Random Access" of Random Access Memory, but yeah in a certain sense it is (very very slow) RAM. Not by the proper definition of RAM of course, but it is part of the virtual memory the OS manages. Technically the swap file memory isnt even ever actually directly accessed, it just gets swapped back into the RAM, with another part of RAM being put in the swapfile instead.

PCIe feels like it went from a consumer standard to an industrial standard really quickly

[@codyhake1932]

Doesn't signal integrity also depend on the software that deciphers it? Say, the faster piece of software can interpret a signal, the more that "signal" can hold? Like say, 8 Track vs Stereo Casette? Both using a magnetic film roll, both having different capabilitie because of the hardware that uses them? Like, doesnt it go both ways? Isn't that why GPUs no longer really saturate the lanes?

PCIe 4 and 5 already feel so new and almost overkill lol

[@Novus_Ordo_Conditor]

I think the reason for this speed increase is that rather than increasing the total speed of the entire PCIE slot, it may be a good indicator that we need to shrink the PCIE slot and maybe even encounter a new generation graphics card mounting system. Think about it, we are now mounting graphics cards like psu because they have become very heavy.

My question for what do i need this? its a l'art pour l'art project?

[@GhanashyamSateesh]

Riley, you forgot to mention the fact that external GPUs could hugely benefit from this. As you know eGPUs are limited to 4 lanes and gen 7 4 lanes equals gen 5 16 lanes! Heck yeah!!! Maybe the traditional desktop form factor will be dead and the thin & light PCs are the future 😮🤯

I want to start seeing x4 and x8 gpu’s and x1/x2 nvmes So I can have more devices that use fewer lanes

[@LRK-GT]

Protip: NVMe (and most PCIe) devices will function w/ less lanes. [I used to run Solidigm P41+ 4.0 drives in X570's 4.0x1 slots] -Optane M10s were Gen3x2, 990Evo is Gen5x2 -RX 6500series were 4.0x4 (M.2 adaptation invitation, IMO) + a myriad of GPUs are x8 (reaching back at least into the RX5*0 series)

So... Can we please get 2- or even 1-lane m.2 ssd?

[@tmmehedi]

Lool.. i am still running on PCIE 3.0😂

[@Kiyuja]

Now that we actually use stuff like GPU decompression and ReBAR, we can actually can take advantage of higher bandwidth of PCI-E. To be honest tho, to truly take advantage of Gen 5 and beyond we need more CPU lanes and chipsets.

Still living in PCIE 3 world gang🙋
