| freebs2 said: From what I've read the Drive PX2 is a board made of twoTegra X2 SoCs and two discrete GPUs. I haven't seen any indication of the X2 being essentially larger than the X1. Also the the fact it has the same count of gpu cores, less cpu cores (although likely larger) and the smaller 16nm node doesn't seem to indicate a larger chip either. But if you have more precise information or better knowledge of those architectures, please explain. |
The thing that is the "X2" is the Parker which is for cars, its made of Pascal-based cores. You're confusing the label "X2" which at this point basically means nothing as its not really succeeding the X1 in the same way which was initially an attempt to push K1 further into gaming and SHIELD, but now has completely moved to automotives.
The NX will not be using the X1, which is based on Maxwell, but a custom chip based on Pascal. The dev kits have maxed out/oc-ed Maxwell based X1s because they can achieve ~roughly~ equivalent performances by being clocked high enough relative to a more efficient Pascal chip. Such a device would need internal cooling or it will melt, and so its not surprising that dev kits (which is what these rumors would be based on) would have active cooling. The NX itself may also have active cooling if it has different opperation profiles between battery and plugged in (much like a laptop).
Pascal is largely about efficiency gains over the Maxwell chips as the shrink isn't that large, but it also has decent performance gains.
That said, anything that is coded to take advantage of Pascal over GCN1.1 will have real world performance approaching that of the twins, but this will depend on where Nintendo clocks this thing and how it is (or if it is) cooled. Also its mobile.
This is much like the Gamecube in how it is designed, a lot of high optimization and efficiency. Also its pretty much the cutting edge of mobile technology.
