. MCM's are SOC's
omg, i know the difference, what do you call a SOC? just because both cores are not direct to each other on say a cpu/gpu set mem package does not mean they are not on the same chip carrier were splitting hairs here in the definition. SOC's are on the same die. which is if you went through the entire break down under the chip spreader it is both chips are on the same die. Now if you want to talk about the connection between both chips that is where were on the same page as far as the speed, but like others have pointed out we have yet to see the lay out of the  connection.s between the chips or its channel of on die connection.

Obviously you don't have the slightest clue of what you are talking about. You bring up buzzwords like "SoC", "Set mem package" (whatever THAT means), "same page" (whatever THAT means), "channel of on die connection" (huh?).

Look, the names have a VERY defined meaning. Here is what the WiiU memory system looks like EXACTLY:

1. Four 256MBit *16bit gDDR3 chips, connected to the large MCM. This gives a 64bit wide data bus (exactly what every single memory controller uses in the industry)

2.  The MCM contains two chip carriers, a large one and a small one. The small one contains the die of the CPU. A chip carrier is a square ceramic/thermoplast thingie with pins or balls on the underside that connect to a pcb and has "stuff" inside do do "stuff" (I have worked with chip carriers that contained almost a dozen analog/digital circuits).

3. We don't know what is exactly hidden inside the large chip carrier. It contains either a single die (with GPU and eDram), or two dies (one GPU, one eDram). Unless someone pries open the large chip carrier (a specialist can probably do that without killing the WiiU), we don't know.  One or two dies, one contains the dram memory controller for the gDDR3 drams (on the picture, you can see the address and data lines going to the large chip carrier). Obviously inside the GPU die, there is a lot of "magic" that handles the further distribution of memory to eDram/CPU/DSP. It is this magic that makes the WiiU powerful, considering the weak CPU/memory bandwidth).

4 What do I call a SoC? Well, SoC is short for "System On a Chip". It is wildly used in advertising for everything small enough that constitutes the "core" of a computer. Sometimes it is used to describe a single die that contains a CPU,GPU and ram. Sometimes it is used to describe a single chip carrier that contains a CPU,GPU and ram. Sometimes it is used to advertise an MCM that contains a CPU,GPU and ram. It is a buzzword, nothing more, nothing less.

you are bing quite defensive for talking about hardware

its a classification of chips system is not just a buzzword its is what it is. 

 

next you insult me with trying to seem like you know what your talking about , but try to tear me down in the process

"Obviously you don't have the slightest clue of what you are talking about. You bring up buzzwords like "SoC", "Set mem package" (whatever THAT means), "same page" (whatever THAT means), "channel of on die connection" (huh?)."

you point out :

"Set mem package" and you say you do not know what that mean's?

you should know you just described it:

"The MCM contains two chip carriers, a large one and a small one. The small one contains the die of the CPU. A chip carrier is a square ceramic/thermoplast thingie with pins or balls on the underside that connect to a pcb and has "stuff" inside do do "stuff" (I have worked with chip carriers that contained almost a dozen analog/digital circuits).The MCM contains two chip carriers, a large one and a small one.

if you google set mem package  look what shows up on the 2nd meaning
