What do we know? Can anyone make a case for skipping Arrow Lake. What distinguishes Panther Lake from Arrow Lake?
 
...using Intel's 18A (1.8nm-class) process technology, which promises higher performance, lower power consumption, and higher transistor density in addition to lower costs for Intel, which will positively affect Intel's margins.

"Our [process technology development] efforts will culminate with the introduction of Panther Lake in the second half of 2025," said Gelsinger.

Looks like Intel will be hanging on to Arrow Lake (desktop) and Lunar Lake (mobile) for a while to save their situation (if not their image).
 
is there any announcement as to what the LGA would be for Panther Lake or Arrow Lake?

LGA1851. I don't recall if it's been officially announced by Intel, but the board and cooler manufacturers haven't been shy about the name. Same physical socket size as 1700 and same ILM. Bendgate status remains unknown.
 
If it's the same physical socket size as 1700, for the sake of less confusion, why don't they leave the name as LGA1700? unless there is something that is not compatible in some way. As the way that Intel normally does it, if it's the same size, they would called it for e.g., 1150 to 1151, so you know the last no. is a mickey mouse change.

regardless, so any LGA1700 CPU cooler will work on these upcoming Arrow Lake / Panther Lake LGA, for people who currently own LGA 1700 CPU cooler, they don't need to buy yet another CPU Cooler?

1. Because 1700/1851/1150/1151 is the number of pins in the sockets. The pin pitch is denser to fit more pins in the same area.

2. Changing the "names" helps people know that the sockets aren't compatible and so they don't try to fit the wrong CPUs into the sockets. (Remember the 100/200 series 1151 vs. 300 series 1151 "v2" debacle)

3. Generally, yes. The cooler/MB manufacturers have confirmed that LGA1700 coolers will work on LGA1851 without modification. However, do be aware that not all coolers will fit the motherboards because of size and component placements, but this has been an issue for decades.

Isn't Panther Lake a mobile platform? I thought Nova Lake was the successor to Arrow Lake.

Ah, you are correct. This many architectures shit is too hard to keep track of.

Looking at some roadmap leaks, seems that Nova Lake is 2026, which might mean a new socket given the rumored existence of Arrow Lake Refresh. Or not. Always hard to say with Intel.
 
The refresh may just be faster clocks or a minor tweak of Arrow Lake. Originally there was supposed to be a higher core count variants of Arrow Lake Refresh in 2025 in 8+32 configuration with some cut down variants but some leakers claim its been cancelled.
 
Panther Lake sounds like it's going to be a successor to Lunar Lake, so it'll go in shiny ultralight laptops & such. That doesn't interest me much. I just don't use a laptop enough to buy anything fancy. There will be "U" and "H" versions of Arrow Lake. Realistically I'm not going to replace my i7-8565U/16/500 laptop in the next couple years unless it croaks.

I'm thinking process switch for the refresh. I'm not sure which leaks/rumors to believe about Arrow Lake since the leaks are a mix of TSMC 3nm and Intel 20A for the compute tile and possibly both. Like the first ones to come out this fall (K models) might use TSMC like Lunar Lake, then more models on 20A early next year. Intel is also working on their 18A process which is supposed to get going next year. Either way the refresh could easily involve a process change, either 20A to 18A or TSMC 3nm to either of those.

Somewhat related and interesting enought to keep my attention.

Interesting. Ditch DIMMs and go faster. Makes sense. Computers have basically been the same shape for decades. ATX & DIMMs date to the 1990s. Before DIMMs we had SIMMs, and before that ram came on full size cards. Like as long as a 4090 full size, maybe longer. I had a 386 with that setup. Cards going in slots date to the original IBM PC and before that, and the slot spacing hasn't changed on PCs. We just have a lot less of them now and a lot of the slots don't have a slot. Meaning there's a slot on the back of the case but no slot on the board. I kind of think it's about time how desktop computers are put together got a redesign. Like why do we have these massive sagging vid cards held in place by a slot and a little clip on the mainboard and 2-3 screws? You'd think people could come up with something a little more stable. M.2 drives also need a re-work. Placing them parallel to the mainboard limits the space available. My board actually has one perpendicular slot. It came with a little metal frame you screw into the board, then mount the M.2 to the frame. Still kinda clunky, and I think we could do better. There's a bunch of stuff that could be done.
