PCI Express 7.0 is INSANE 

PCIe naming is just the opposite of USB

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.

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.)

​@@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.

The "what" is easy-ish, knowing how to do it is why one gets to the SIG.

More like: THREEEEEEEEEEEEEEEEEEEEEEEEE FOURRRRRRRRRRRRR FIVE67 lol. Six was released yesterday, I swear!

4 was shorter than yall think

It really doesn't feel like it but the time between 4.0 to 5.0 is shorter than 2.0 to 3.0 (2 yrs vs 3). 5.0 to 6.0 and 6.0 to 7.0 are also 3 years apart respectively. I legitimately thought the 6.0 video came out last year lol

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. Then I don't honestly even remember so much as hearing about 6.0 and we're now on to 7.

Pcie 4 was available with B550/X570/Z590, proper availability with A620/B650/X670... Which is when pcie 5 was made available. There wasn't even a full generation of wide availability for PCIe 4 before 5 came out.

nice

These jokes would be better if 4.0 wasn't out for more than a year on laptop.. Like manufacturers have plenty to make fun of. We don't need to make up any.

​@@josephgood2704You just didn't get it

Still on X9000 cpu with ddr2 667 2x4 on the laptop lol

​@@josephgood2704he is broke so he's gonna get an old laptop

Yeah that is strange. I just switched from 16 GB DDR3 to 64 GB DDR4 about 2 years ago. Now we already talking about DDR6 soon :D. Before that I was having DDR3 for like 10 years straight. At least I got a PCIE5x16 slot so if GPUs are gonna need it I'm gonna have it. But NMVEs still gonna just be PCIE4 x4 for me for years to come. Well I still have my 2005 320 GB HDD with low health installed in my new rig as a side storage so I see no problems there.

Just PCIe. DDR6 isn't happening soon.

Yup, still on 3.0

​@@williehrmann DDR3 stopped being current on consumer platforms in 2016. So you may have been running it for much longer than that, but it was not modern for quite that long.

@@dawnraider0072 My 10 year old DDR3 PC still runs Windows and most games I play very well, I remember things going sluggish much faster and by a giant degree back in the day, maybe it's a Windows Vista era bias, idk.

I’m still on PCI-E 3.0 🤣

It felt like PCI-E 3.0 was there for like my whole life, and now every other year there's a new standard. Time flies.

Pcie 5.0 was released back in 2019 and there still isn't a single consumer GPU that uses it. So soon isn't the word I'd use for 7.0

to be fair pcie 3 and 4 don't really affect fps all that much

@@OrionCV1 i looked up some stats on my rtx 3050. On Pcie 4 motherboard it has about 12% higher performance than pcie 3

...but still only 75W power delivery via the slot.😉

Waterblocks for redrivers 😂

Well thankfully your new $120 per foot, 2 inch thick USB 6.1d/ThunderBolt 11 cable can run the AIO pump. But nothing else. Because it's the cheap one from Amazon Basics.

PCI 5.0 really needs cooler otherwise it will get overheated and performance will be reduced quickly

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

So kinda like the Apple ones and the new Snapdragon

What if you could change a chipset like you can with a cpu

Those are systems-on-chip and have been common for several years, eg. AMD Ryzen and EPYC CPUs

That's called an SoC

How awful. Didn't they know they are OBLIGATED to make everything immediately useful for basic folk DAY 0!A!1!!!

​@iambenmitchell doubt all you want. Once you move away from pushing pretty pixels, there is a need for the high bandwidth and features afforded by pushing this spec. Hence why it's pushing. While the video games aren't demanding that much, other areas are an entirely different story.

@@MaddJakd yes. I know that. That is why I said "Outside of the server space" 🤦‍♂

maybe if you turn off ray tracing

​@@mrkcrtr508not enough, might need to turn on frame gen 4.3

$3000 of that is the GPU *sigh*

Of course, just need to check the monitor's settings...

​@@Tanks_In_Space Is this memes?

basically may as well as next years graphics cards will just start needing them, at least the one/s better than the 4090 desktop lol.

I believe PCIe 5 is on AM5 and newer Intel chips. PCIe 6 is likely an enterprise thing at this point. We won’t see PCIe 7 anytime soon.

5 exists but they just skipped 6 or it existed only behind closed doors

6 was announced in 2019 and 7 in 2022

5 wasn't released outside of Japan because they thought it was too difficult, and 6 was actually localized as "3" (this is a Final Fantasy joke, I have no earthly idea why the PCIe standard is so far ahead of what people can actually buy)

​@HontoNeet It makes sense when you think about it. It's always been ahead to some degree. If you were planning a city and anticipating a lot of growth you'd make the highways wider than immediately needed.

apparently for home use a gen 4 is even still way above and beyond what's needed as the rtx 4090 just barely fully utilizes a gen 3.

im here chilling with PCEe 3.0 and DDR3

​@@RandoWisLuL me too 😀

@@TitanRocks619 haha nice

@@RandoWisLuL Me too 😁

meanwhile chilling here with PCIe 2.0 & DDR3

Yeah, but the option reduce the lanes would be great.

@@tobylegion6913 Bad news, there's a trend that Mobo manufacture giving you less and less PCIE split

It doesn't matter for consumers as you can't bifurcate them anyway and most consumer devices that will go in those slots wont be pcie6.0/7.0. : / Lets say you have your pcie 5.0 and @x8 its as fast as 4.0@x16. But your GPU is 4.0 so it still will need all 16 lanes, nothing gained : / Now lets say you have some other GPU/device thats pcie5.0 and since its so fast it only needs x8. So you have x8 left and youre happy. Aaand thats when you start digging and go into rabbit hole of pcie layout on motherboards and bifurcation options (lack of them...) and you realize you cant do much with that x8 cause you cant divide it into x2/x2/x2/x2 to connect four ssds, you cant even divide into x4/x4, you have to waste 5.0@x8 on single ssd regardless if that device is x2 or x4, 3.0 or 4.0 or 5.0... : /

Were lanes limited not bandwidth limited. We have pcie 4.0 motherboard with x16 slot, x8 slot and x4 slot we can connect 3 devices. We have pcie 5.0 motherboard with x16 slot, x8 slot and x4 slot we still can connect 3 devices. We will have pcie 6.0 motherboard with x16 slot, x8 slot and x4 slot we still will only be able to connect 3 devices.

@@sznikersare you a primarily Intel user? It’s been a thing on AMD consumer boards for quite a while now ever since AM4, AM5 supports it as well. In fact it’s straight up just supported by AGESA it’s just up to the manufacturers to expose it within the bios.

@@NawWeeMan on intel its exactly the same "just up to manufacturer to put it in bios" ... : / They don't, squeeze on pcie lanes forces people into higher price bracket pro hardware (threadripper & sapphire rapids).

@@sznikers I’m questioning if you have used AMD because AMD board partners do expose it the majority of the time, it was exposed with my AM4 Asrock board and is currently exposed with my ASUS X670E-creator board. It’s rarer for it not to be exposed than exposed. Maybe the budget B Chipsets don’t expose it? I have no idea.

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.

I think you already can hot swap GPU like that, even with pcie 3.0

@@cinderwolf32 yeah, but the connector is really big and more of a lane than a connector, with a plug you'll be able to move the GPU everywhere. Yeah, there are exteenal GPUs for mobile, but not for desktops

@@TrioLOLGamers PCIE optical extension already exist, like any hardware PC enthusiast dream of. The problem is It's only for enterprise and PC community keep expecting enterprise grade hardware with fast food cost.

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

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

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.

@@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.

Gen 5, 6, and 7 at the moment are not really meant 'for consumers'. Even consumer-available Gen5 PCIe x4 NVMe SSDs, are (IMHO) only 'a value' for for-profit content creators, media professionals, and high resolution photographers, etc. People who are making money, and are losing it waiting on data to on-/off-load from a drive. 'Big Data' and the growth/integration of 'AI' in business is what's driving wider and faster interconnects; we get 'the trickle-down'. The amount of data needing to be processed and stored is orders of magnitude larger than anything us home users/gamers would ever see.

More like $1500 this is server only for now

I'm so sorry for your loss 🫂

Sincerely, my deepest sympathies.

Sorry, you're too fast for gamers. But too slow for data centers

We can, but motherboard manufacture says otherwise There's so MANY motherboard that originally has x8 PCIE split socket but now they only provide 1 direct CPU PCIE.

It didn't. 5.0's been out on desktop and server for awhile now. 6.0 has limited deployment in-industry.
