Intel LGA1851 to Succeed LGA1700, Probably Retain Cooler Compatibility
Intel's next-generation desktop processor socket will be the LGA1851. Leaked documents point to the next-generation socket being of identical dimensions to the current LGA1700, despite the higher pin-count, which could indicate cooler compatibility between the two sockets, much in the same way as the LGA1200 retained cooler-compatibility with prior Intel sockets tracing all the way back to the LGA1156. The current LGA1700 will service only two generations of Intel Core, the 12th Generation "Alder Lake," and the next-gen "Raptor Lake" due for later this year. "Raptor Lake" will be Intel's last desktop processor built on a monolithic silicon, as the company transitions to multi-chip modules.
Intel Socket LGA1851 will debut with the 14th Gen Core "Meteor Lake" processors due for late-2023 or 2024; and will hold out until the 15th Gen "Arrow Lake." Since "Meteor Lake" is a 3D-stacked MCM with a base tile stacked below logic tiles; the company is making adjustments to the IHS thickness to end up with an identical package thickness to the LGA1700, which would be key to cooler-compatibility, besides the socket's physical dimensions. Intel probably added pin-count to the LGA1851 by eating into the "courtyard" (the central gap in the land-grid), because the company states that the pin-pitch hasn't changed from LGA1700.

You win :toast:
Didn't read the rest of your post. Probably I am losing some great arguments that totally destroy mine?
Well....who cares?
You also need to shovel around some data (if you have your game library on the same drive quite even more). And if you're a perfectionist it'll take even longer. :laugh:
I thought you meant Socket 754/940/939 followed by Intel long-lasting LGA775. Athlon 64 days were truly AMD's doing, on purpose as well as bad market strategies.
Now I'm testing a 12600 also with igp. Processor and motherboard = 320 euros. As gaming is excluded on this system, the cheapest video card that can offer what UHD 770 offers is RTX 3050 (6500XT does not decode AV1 and does not include encoder). The offer from AMD in that price range is 5600G, much lower in performance, better in gaming but very weak in decoding (Vega, deh, not RDNA2). If you run youtube or netflix with it, an intel consumes 40W, the whole system, and AMD consumes at least 40W only the processor.
There are cases and cases, and for 12900K or 5950X we have a lot of tests to compare them.
PS. If the motherboard supports 3 or more series of processors, I would only use it if I make the leap to the next, not more. I only change a motherboard, not the car.
And I didn't say "insert an 11900K in the Z490". I said "insert an Alder lake". Can you? You are testing in on Z490 I assume.
Are you in the video making industry or are you trying to find excuses where AV1 decoding and probably encoding is what maters most in this world? So 20-30W in video playback plays a huge role, but 100W difference in multicore does not? Nice.
Still trying to find specific cases and then come to general conclusions I see. Of course we mention but at the same time exclude/downplay cases where the competition is having the advantage. And we are back to 12900K vs a 2 years old CPU. We have a lot of tests to do you say, still a few lines above AV1 decoding and encoding is what people are doing 24/7 I guess. The alpha and the omega in today's usage. Right.... As you say, YOU. NOT everyone else.
I didn't got the car example, but no reason to explain yourself here. I am pretty sure you will grab one line of my post (you have plenty to choose), distort it and build a new argument about why Alder Lake is the best option.
Meanwhile, an AMD user kept upgrading just to end up where the Intel user was 3 years ago. LOL
Besides Intel had 3 variations of 14nm node, also RKL was back ported on 14nm just to "fend off" AMD :nutkick:

Btw any SKL derivatives with extra cores, & extra cache, had higher "IPC" & higher ST performance! Think of it as Intel's x3D's :D
The extra cache of course is the key aspect.

In case you want to see some other reference point ~
And again cache matters, not just cache per core otherwise you wouldn't see the top end parts being decisively ahead of their predecessors!
Ciao, keep entertaining yourself with that kind of knowledge :toast:
