ceramic vs organic packaging

@md0Cer · Nov 20, 2003

Ive searched and searched and i havent come up with anything so i might start a thread on it. Why do the Athlon FX's use ceramic, and the old tbirds, but why is everything else organic packaging? Does it matter which is used, are there benefits to using a different one vs the other?

TIA!

Athlon FX-51 Ceramic:

Organic is cheaper to produce I beleive. Possibly for some reason the ceramic works better in the design of the FX series for some odd reason?

well my guess would be it alows for a bigger area for the heat disapation. this way the processor will run cooler while more watts of heat are generated.

or they knew people chip the cores of there organic core so they made them with ceramic so this would not happen.

wildfrogman · Nov 22, 2003

Nope, the cores are still silicon. The packaging is the area around the little raised core. I am thinking it may help in the design of the cpu traces and what not to keep cross talk down and allow the cpu to run faster.

cost.
Organic is cheaper

i say its cost

georgelogy · Nov 22, 2003

Cost is a part of it, but there is also other advantages as well, namely, improved dielectric materials in organic packaging.

It could be that AMD found a better way to implement ceramic packaging, and is using it on the AthlonFX.

You can read about the differences of organic vs. ceramic CPU packaging from Intel here:

Thanks for the info everyone!

Cheers!

I think the Durons are organic too. That would further support the cost idea.

@md0Cer · Nov 24, 2003

yea probably. They migth make the organic for the opterons becuase it looks more expensive/higher quality. Although I like the nice color that the organic is vs that dusty violet. I do beleive that the older durons as well as tbirds were ceramic. I remember someone saying something about how the ceramic packaging is much stronger and ALOT harder to make keychains out of vs the organic, so maybe they need a stronger material to hold the greater number of pins during the manufacturing.

How about protecting the bridges (now pcb traces) from picking and manipulatiion. Organic you can scratch through, try scratching through a Ceramic PCB. MUAHAHHAHHAAAHAHAA

Isn't the whole top of the FX covered with an IHS anyway? Now you have to get through the ceramic in addition to a big hunk of metal.

Quailane · Nov 25, 2003

I don't think that that is a reason as AMD has shown that even though we can scratch through the organic to get to the bridges, we still can't do anything with them on the barton.

Well, ive seen people get the IHS (Integrated Heat Spreader) off of the P4.

So on these new ones I think i remember seeing a pic of one with the IHS off, and i could not see any bridges, so i assume you mean that they are submerged underneath the PCB instead of exposed like on the K7's?

ill try to go find that pic.

I cannot find it anywhere. I did find pics of the fx-51 and the A64 though. THey are in my origional post.
