AMD's Quad cores have large advantages over Kentsfield - Page 14

The bad thing about that is that when 22nm rolls around, we'll be eagerly waiting for the next process and so the cycle continues.

On a side note, I just had a thought... Since AMD is leveraging cHT to get 4x4 to work, why can't they just do what Intel is doing by putting two dies in the same packaging, execpt joining the two dies with cHT links? Wouldn't that solve the problems with the inter core communications? The individual dual-cores will be able to communicate much faster than the fsb approach. I'm guessing there would be a bit more latency than native quad-core, but would be way faster than using the fsb. Also, this would greatly increase the yields as they can join any two dual-core dies. They could probably even make dual-cores this way by joining two single core dies. Could label them as Sempron X2 since it's not native dual-core.

Does this sound too farfetched? I wonder why AMD hasn't gone this route. I'm sure they have weighed this option before as they are not stupid but I'm curious why this doesn't work.

Thats what I was thinking. AMD is planing on shrinking the K8 to 65nm this month, so why not use two 65nm cores under the same IHS instead of two separate 90nm cores?

That is pretty much what they're doing, only without having to put 2 cores on one die. I'm pretty sure it is cheaper to make this way?

Everyone ignore everything I wrote in response to alk's post

EDIT: That should say 2 dies on 1 proc and not 2 cores on one die

Not too the retail market yet. AMD isnt very giving with sample ES processors, never have been.

Im saying people have been testing them. I hate these debates because we need actual hardware tested by overclockers to give an accurate statement about how good they really are.

That's actually why these debates are so much fun..... since we're talking about hardware that's not out yet

Gotta love hypothesizing

Im just saying its lame to see all these "claims" about how good something is before its in the hands of people like us. Its like conroe when it was almost out. Bs everywhere.

Think of it this way: Eventually I'll have to upgrade because I'll actually need the processing power. Right now I just web browse and listen to music, no need to have fancy toys in the here-and-now. I'll also have skipped 3 processing cycles, 65nm, 45nm, and 32nm, what a jump . If theres a fast enough release cycle, I'll wait longer, but eventually i'll get sick of these old things and upgrade for the sake of it.

That's just a stop gap, joining two processors on one piece of silicon. Intel has done this manuever twice now and AMD stomped them for it once already... Plus AMD is just making the transition to 65nm and likely doesn't want to invest any resources in the temporary solution. They're wise in not attempting to mirror Intel's latest, but merely offering something comparable, the 4X4.
