Intel's Upcoming LGA-1851 Socket Detailed

[TheLostSwede]

Igor Wallossek over at Igor's Lab has posted a range of technical specs for Intel's upcoming LGA-1851 socket and it covers everything from the pin-out to the mechanical characteristics of the new socket. The new socket is intended for Intel's 15th gen Arrow Lake S CPU. Raptor Lake refresh, which will launch as Intel's 14th gen—and last generation—Core i desktop processor, still uses LGA-1700. Although the new socket has additional pins, the physical size remains the same as the LGA-1700 sockets, so it's expected that current coolers will remain compatible with the LGA-1851 socket. However, the mounting pressure has almost doubled from 489.5 N to 923 N, suggesting that a different mounting kit might be needed.

What is more interesting with regards to the new socket is that Igor confirms that Intel will be adding four PCIe 5.0 lanes for a CPU connected NVMe SSD, but apparently Intel will also keep the current four PCIe 4.0 lanes for a second CPU connected NVMe SSD, not quite matching AMD's AM5 platform. It's likely that we'll see a similar segmentation like the one AMD has done, so only Z-series chipset motherboards will be able to take advantage of the PCIe 5.0 NVMe lanes, but it's possible some other chipset SKUs from Intel will enable PCIe 5.0 storage support as well.

The description would lend me to believe the socket Rev. is to add more high-speed PCIe interconnects.
Which, reminds me of Nintendo's hardware strategy: Purposefully leave out expectant features, so you can sell another (revised) product, at a later date.

Makes me wonder if AMD was similarly short-sighted and there'll be an AM5+ socket (ala AM2 - AM2+ - AM3)?

On one side we have one of the largest market contractions in PC history, and on the other we have plans from manufacturers to just try to sell mediocre upgrades - CPUs and GPUs that have higher price increase than performance increase, motherboards with less functionality for more money, SSDs that are actually reducing capacity (ommiting 4TB size altogether)...

And then they'll surprise Pikatchu face in next quarters when market will contract further, everyone just accepting their old PC is actually just as good as the new, 50% more expensive one!

Well usually what is shown is a bunch of hope and ideas, guidelines, something they want to do, but when it comes down to actually making it happen it proves to be too hard or not effective.
This is why it usually takes longer.

Heck frame generation was shown off in Star Wars the Force Unleashed 2 as a concept, yet as an actual tech we are only getting it now.

A new Intel socket?! This very likely has absolutely nothing to do with the fact that so many chips on those motherboards are branded as Intel. Nope, they have zero vested interest in making even more money off of their customers by forcing their motherboards to be irrelevant for upgrades. Only a fool would point that out and say it's a "rebuild" to replace your motherboard and CPU but nope! Definitely nothing fishy there!

Will the retention mechanism still be the side tabs, or will Intel make something to even the pressure along the whole IHS?

Leakers not even waiting for 14th gen to be released , everything moves so fast now.

The mounting pressure was already high enough on LGA1700 to make me use the thermalright contact frame, it just felt like something would give with the amount of pressure needed (and probably would be the case with warp).

the loading mechanism that Im going to use. lol

It appears to be unchanged.

We're talking Q4/2024 or Q1/2025 material here, right? It would be utterly pathetic if Intel would still not be able to match AMD I/O by that timeframe.

I think everyone understands that Intel has had some gigantic hiccups in their fabs business. Yes, TSMC now has a lead of easily half a decade (or more) and thus Intel can just barely compete in performance and not at all in efficiency.

Intel is limping behind by years. We get it. All of that is mostly understandable and sh*t happens in this extremely complex tech business.

However, if you can not compete on a leading edge level with regard to the chips/cores then the VERY LEAST you should try to do would be to take the lead in all other areas like I/O, QoL, usability, whatever. It would be incredibly disappointing if Intel would fall way behind in these other areas as well. What the actual f are they doing?
