I was interested in the new AMD socket AM5 and ran across this video. Apparently MSI posted it but wasn't supposed to ... but someone else captured it and reposted it. I guess it isn't all that super-exciting but it does show the direction they went. Sortof like Intel sockets.
Here's a link to it if anyone is interested -

I was wondering when they'd finally embrace LGA.
That heatspreader's chunky, I wonder how thick their die stack is.

Metal heatsink is like that to have the same final height as a socket AM4 cpu would.
It allows reuse of socket AM4 coolers - the boards have same screw holes, same metal backplate, same plastic clips that can be removed if the cooler uses screws...etc...
Saves money and reduces waste.

Yeah thing is that the LGA socket is a lot thinner than the PGA ZIF socket it used before. So in order to be compatible with old heatsinks they seam to have made up the height in the heat spreader.
Perhaps with the new chiplet design the thick heatspreader can be useful in getting the cooling performance to the parts that need it the most.
I was more of a fan of the PGA design since it is more robust. The LGA pins can get easily damaged if you are clumsy and drop the corner of a CPU in the socket while putting it in. I guess more of an LGA advantage is that they can get more pins in the same area and they are well suited for high speed. Something that definitely comes in useful with the huge amount of IO these new AM5 chips are supposed to be capable of.
