Hello All,

 

something is bugging me a while.

 

we know that AMD uses chiplet designs but between chiplets a CPU always has a bit less performance (over the InfiniBand).

so it would be better having only 1 corechiplet (marginally but theorizing here.

 

when looking at the lineup of all 4 new CPU's it can be checked as if every CPU has 2 corechiplets. but design white that would be very inefficient production.

so i was checking the CPU's and they can be paired by 2.

 

 

this would be if everything has 2 chiplets

 

  chiplets cores per chiplet cores total threads L3 cache (per chiplet) tot cache stock boost
5950x 2 8 16 32 32 64 3,4 4,9
5900x 2 6 12 24 32 64 3,7 4,8
5800x 2 4 8 16 16 32 3,8 4,7
5600x 2 3 6 12 16 32 3,7 4,6

 

but if production pairing will be a thing:

  chiplets cores per chiplet cores total threads L3 cache (per chiplet) tot cache stock boost
5950x 2 8 16 32 32 64 3,4 4,9
5900x 2 6 12 24 32 64 3,7 4,8
5800x 1 8 8 16 32 32 3,8 4,7
5600x 1 6 6 12 32 32 3,7 4,6

 

 

here the 5950x is paired with the 5800x and the 5900x is paired with the 5600x. that means instead of 4 parallel chiplet's they can produce only 2.

would that mean that the 5800x and 5600x be a bit more 'efficient' with their performance. And also, better thermally since there is less 'stuff' under the heat spreader?

That's not how it works. AFAIK they only manufacture one chiplet type and bin them, that's how they save. Those that have fewer than 8 cores active in a given CPU have some disabled, which allows to "recycle" chips that have faulty cores instead of throwing them away, increasing yields/savings, precisely the opposite of inefficient production.

Thermally more "stuff" is better, the larger the cotnact area the better the transfer between die and IHS.

AMD Only makes one kind of chiplet for Desktop. an 8-core one. CPUs like the 5900X or 5600X which use 6-core chiplets simply use the 8-core chiplets and disable 2 cores. (which is convenient if the chiplet happens to already have a defect in one or two cores, in which case 2 cores would need to be disabled anyway)

AFAIK The 5800X and 5600X are actually only 1-chiplet, and are exactly as you describe.
