Seeking clarification on AMD specs

[BecauseICanTBH]

I'm considering going with a TR 3960X instead of the i9-10980XE for my next upgrade (this month). I'm confused by AMD's specs though. Can somebody familiar with their ways clarify the following for me?

 

1. They say "a total of" 88 PCIe 4.0 lanes - when combined with a motherboard. How many of these are actually CPU-based PCIe lanes? Is there anyway of knowing? Chipset PCIe lanes have a greater latency AFAIK. 
2. Their "max boost clock" is listed as being for only 1 core. Is there any boost for all cores like Intel has, or they're just locked at base clock except for the one that gets boosted?
3. The "max temps" (?) is listed at 68c. I've seen a lot of confusing info on this about AMD adding or subtracting 20 to 27 degrees from that temp. Some have said that it's a case temperature and not die temperature. I ultimately still don't understand it. 68c is a very low temp for a CPU to be throttling at. Can someone explain this in simple terms and perhaps link a source? Better yet, could you compare it to the way Intel lists TJunction temps and give me some familiar ground to interpret it?

 

Thanks for any help you can offer on this.

Don't know much about AMD I have a PC with an a9-9430 but that's it I believe that it's just a typo but boost on 1 core isn't very good. How many cores does it have

we wont know until the block diagram is released which to my knowledge its not been yet for the new socket since the new Threadrippers will use a new socket.

1. Look at block diagram for the board. Many of the lanes are up to the mobo maker to decide to use them for pcie, nvme, or sata.

 

2. Not really. Boost depends on many things like the type of load(avx will be at a slower clock for example), and the temps, boards bios, os settings, and other things. Wait for reviews for average all core boost.

 

3. Wait for reviews, this is probably just when it start to limit boost due to thermals.

 

Really, wait for reviews, this part isn't even out yet.
