Not sure if anyone has mentioned this but if it's only 4 chips (we can't see underneath the motherboard) then it's definitely DDR3. What's more important is that the eDRAM is on-die for both the CPU and GPU so you're going to have a ridiculously small amount of latency. Good times ahead! |
The easier way to know if it's GDDR3 or GDDR5 is to look at the memory traces. If all of them have approximately the same length, then it's gddr3. If they have very different lengths, it's GDDR5, as GDDR3 is much more sensible to different memory traces resistance, and the traces resistance depends on the trace length. GDDR5 has made the PCBs much easier to design, as you don't need as intricate paths as with GDDR3.
Looking at the traces, it seems that the memory standard is GDDR5 or DDR3, probably GDDR5.
Another point is the number of chips. AFAIK there aren't any 4 Gb GDDR5 chips, so if you want 2 GB memory you need 8 chips, so the most probable configuration is 256 bits memory channel, and 8 chips, or 128 bits memory channel with 8 chips on a pop configuration (2 chips package on package sharing the same 32 bits bus, this is a cheap solution thinking in the future 4 Gb chips, but this is inefficient in the short term)
PS: Talking with lilbroex of nintendo hardware is like talking with a zealot.

It'll be DDR3, not GDDR3 or GDDR5. GDDR3 would be way too expensive, it's pretty much dead as an option for memory these days. GDDR5, as you've already stated, would be 8 chips and, again, would be a great deal more expensive than DDR3. It'll be highly clocked DDR3 with the eDRAM preventing any bottlenecking issues imo.

Yup, you are right. I forgot to consider the 4Gb DDR3 memory chips. I don't like that option, relatively low memory bandwidth, but it's cheap.
@lilbroex: A zealot is one who is characterized by fervor for a person, cause, or object; eager desire or endeavor; enthusiastic diligence; ardor. In this case, the power of the WiiU.
