Scooby Doo and the gang unmasking this ghost as SLI/Crossfire

x16 is all you’ll ever need - bill gates, probably

Thank you Mr. Handsome Mustache man

PCI-E does support x32 single link devices, even if it does not use a single socket. It is specified in the PCI Express capability. There is also x12

This just sounds like SLI/Crossfire with extra steps

Back in the day X32 meant something different to us entry level audio production folks 😂

A pretty good slot to put in your Virtua fighter cartridge

1:30 the binary says: "Robert was herrr" 🤓

Riley Yoda needs to be a regular thing.

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. Of course its still PCI-E a migration from PCI and that has its bottlenecks but when you want parallelism they do it very well. (Not affiliated; just impressed)

0:18 You guys worked really hard on this shot; you probably should’ve stayed on it longer. 😂

SLI and crossfire failed back then, but with modern high speed interconnect tech, I think we can bring it back.

So... This is just SLI?

That just sounds like SLI with extra steps.

... You telling me I don't need it. I'm an American. I don't need multiple 64 thread Ryzen Epic servers. But I got em, and they got 128 PCIE lanes each!

MSI tech support are the worst in the industry. You know what they told me? This is verbatim: “We don’t troubleshoot incompatibility”

The Mellanox NICs also allow them to be connected to PCIe lanes from both CPUs. It levels out the network latency by not requiring ½ of the traffic to jump an interprocessor link to get to the NIC.

Simplifying complex tech stuff like PCI Express x32 - just brilliant. Keep up the informative and clear tech explanations.

GPUs are getting so wide these days, they might as well support PCIe x32

Now let's wait for x64

I glanced at the thumbnail and thought it was about a new longer x series barrel for p320 for some reason.

LTT is like the MCU where this video is just setting up the next home server episode.

3:58 I like that the connector is labeled as "black cable" even though it's not black.

"I'm sure some of you are already thinking of ways you can justify your purchase." Wow, calling me out just like that?

lmao 2 4090s on one card would be absolutely insane

In the early 90s even simple soundcards need the ISA slot...and were long an beefy.

This video reminded me of SLI. The physical setup looks identical, you got two devices occupying two PCI Express x16 slots and have an extra cable/connection between the devices.

I am glad that we got SLI PCIE before GTA6.

Doesn't the most recent Mac Pro have a double PCIx16 link to their custom AMD GPU?

A 32 lane PCI bus, awesome! GPU card makers can use it for their premium cards...and only use four lanes. Awesome....

last intel mac pro had two 16x slots combined for dual gpu amd cards. I guess technically that’s 32x

Cisco iirc has a PCI-E x24 for their MLOM + NIC (they may call it a VIC) on some of their stuff.

In FPGA is fairly common to see X32, Microsoft had a board that allow u to control two FPGAs with this lanes, the trick was even it was an X32 actually it was like emulating the connection been two X16 lanes by readdressing the lanes.

Reminds me of those old school gargantuan 16bit ISA slots used to overcome speed limits.

x64 just needs 5 more to work properly...😏

that was the best quickie I've had in years.

I KNEW IT, i was sure I've seen an oversize PCIe somewhere!

The end pointing the reference to Linus got me dead 🤣🤣

0:00 woah MSI Z68A-GD80 that was my first ever gaming motherboard that baby Linus is showing.

In the early 90s, I had a custom Orchid super board with an Orchid Fahrenheit 1280. It's a 32bit Vesa local bus. All my friends were jealous of it's gaming performance. But it didn't get accepted mainstream.

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..

"Not fast enough? Just add more lane!"

I would love it if using one PCIE slot didnt disable another. I dont think we're ready for the jump to x32 until this bandwidth limitation for lanes is addressed.

Thanks for the video!

0:26 that’s what he said.

Every time you say 'Dad a Center', a piece of my soul dies.

X32 is often used to connect 2 server nodes together

My god that segue reminded me of STEFON in SNL... The MSI MPG Gungnir 4000 Battleflow Monster Extreme has EVERYTHING!

so... every SLI rig was running x32 all along?

I've seen server motherboards with X24 physical slots that just connect to exciting PCIe switches.

it still cracks me up whenever someone says dada instead of data

After you said "beyond 16 lanes..." my pc froze for a moment. LOL!

Wait a minute. That binary looks suspicious. All either having started with 01 or 011. It's ascii! Quickly, someone translate it! Edit: ive noticed some binary as 01000000 which isnt ascii, but it is 1 away from capital A. BUT, A huge majority of the stuff looks like readable letters

The last time I saw a product with an x and a 32 next to it was in 1994. That didn't go well! Here is hoping this is not a gimmicky in-between product and is an actual leap into the future. #SEGA #32x

x32? Meh. x32 RGB? Oh, HELL yeah!

Of course I knew, the server in my basement has two of them... although it just uses them for risers with different slot setups.

Now we just need Desktop Chips to actually provide a reasonable amount of lanes so we can have 4 or more X16 slots

Video idea- Usb-c Explained: Everything about the Usb-c type and all its types!

Im casually waiting for PCIe x64

wonder how many years it'll be before PCIE X16 is phased out..... remember how long AGP slots lasted for...... only time will tell..... and who knows what it'll be replaced by....

There are also OCP ports

Pour one out for the man-hours spent on the 1-second star wars clip at 0:18. Worth it.

my mum walked past and asked if i was watching something with steve carrell and i'm never going to unhear that.

1:47 The way you explain that sounds a lot like SLI graphics cards.

Looks over at the EDSFF 4C+ slot a PCIe x32 slot in wide use in server PCIe cards. I guess we wont tell him about you.

Riley sounds like the announcer from the price is right when he does his sponsor bit

So, is this the future of SLI? 16 lanes talking between the GPU’s on the board and 16 lanes talking to the cpu? From each gpu?

Technically, a pcie gen 5x16 slot is like a pcie gen 1x256 slot

need all that sweet x32 for the next great A.I. film, music, art and book creation app / bit miner.

It need in all the lanes to arrive the bits at the same time, routing 32x x2 (each lane is a differential pair) , 64 tracks to trace all to the same chip is very hard, all traces must have the exact same lenght, or there will be penalties, delays penalties.

With 3kg+ graphics cards a long slot would be a good idea long as it can still accept 16x. Extra power too, maybe 4050 work without cables and no card droop.

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

All I heard was it was not SLI/Crossfire's fault it died. Twas complex graphics drivers that killed the beast.

I feel the bandwidth could be used by an SFF with some sort of breakout expansion slots.

I'm still surprised optical connections aren't used yet (again? (SPIDF)). I'm expecting USB (or whatever apple calls it next) to have a fibre down the middle in that tiny blank part of the C connector at some point. Bend insensitive SMOF is cheap enough now that is plausible at scale. SFPs are getting there too.

Kind of ironic since Intel‘s current LGA 1700 platform is pretty bad regarding PCIe flexibility, for example not being able to do PCIe Bifurcation.

Imagine they bring back SLI/Crossfire via PCIE-6.0 x32. Imagine 2-4 5090s or 8950 XTXs in one rig pushing 8k 4+ rays and 4+ bounces path tracing at 120fps.

That ending was great 😂

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

Miss my a8n32x sli fsb would post above 340 nuts board handled anything I tossed at it back then. Will be missed ( oh it's in a box still memories)

so x32 is just two x16 in a trench coat?

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.

Notice this, the shade of his sweater is so close to the shade of his hair, the green screen is in trouble..

GPUs with two pcie slots coming soon 🗿

Riley saying slots so many times is TIGHT

Would a dual gpu card benefit from the x32 possibly allowing for more gpus in a smaller space in a sever?

On that new case from MSI, I don't think I wanna buy something that I can't pronounce.

You could just make the video card with a ribbon to another PCIe slot. GPU's are already double wide.

I was just wondering this yesterday

It would make sense if the GPU and AI is on the same card, but with separate lanes to the motherboard.

How many PCIe lanes do you need to play Crysis?

2:20 but seriously at this point you won't be using consumer grade hardware, this is in the area of high end server and custom equipment.

So using this system it would be theoretically possible to have two linked x16 slots with an rtx 4090 in each , this would give a backdoor form of sli ....

At the end I somehow thought Riley was going to say QuickTechy.. ah, maybe next time.

Actually DCs are already deploying 800G and moving to 1.6T

apparently it’s up to 800G now

yup. and i also just hinted an "idea" in one of recent digital foundry's video comment section about : independent GDDRxX memory module/sticks in M.2 form factor.(could come in any format, 2230, 2242 or 2280) for MULTI PURPOSES of usage cases. from adding more VRAM to BOTH iGPU and discrete GPU, to actually adding CPU fast remote cache(extra huge L4 cache anyone?). i see a market for that. i hope somebody pick the idea up. imagine you have an iGPU, and then simply plug an M.2 16GB GDDR6X memory sticks into one of your M.2 slots, and have the iGPU driver to recognize it and have some instructions to use it, will make your iGPU has 16GB of GDDR6X VRAM. and your CPU could steal some of the paging of it for its "extra cache" of theoritical L4 cache. your OS simply need to add instuctions to use it if it detected available.

So it's Crossfire/SLI for server network cards basically.

Sounds like the old SLI at full speed

So PCI is the new SCSI...... word.
