I'm not questioning it being a family of devices, but I am questioning why people think it will necessarily be initially 2, rather than 3 or one. I guess I'm also questioning if 1080p Wii U games will really bring in the crowd that 720p Wii U games failed to.
The purpose of porting over Wii U games isn't to use them to sell NX, it's to bring in a bit of extra revenue from games that cost a lot of money to develop and only saw a very small audience on the Wii U.
The reason that everyone's assuming two systems are initially released is that a large portion of their potential audience (particularly in the west) has no interest in a handheld system, and another large portion of their potential audience (particularly in Japan) has no interest in a home system.
I'm gonna try again, see if Thraktor or Blu can answer this. My previous post did not get noticed:
What do you think Nintendo should/could target realistically and how would it perform compared to XBO/PS4?
Sorry I didn't see your previous post, it can be difficult to keep up with this thread.
What Nintendo could do, what they should do, and what they will do are probably very different things. It depends very much on when they release it, what price they're planning on selling it for, what added cost the new controller might add, whether they're intent on competing with MS and Sony on performance, what their attitude to case size and power consumption are, etc., etc. After the Wii U it's very difficult to tell what kind of route they may take, and it's probably best to just look at the options open to them for a late 2016 release, rather than try to predict what they should or would choose:
CPU
Best case scenario:
8-core A72 @ 2.2GHz (purely for games)
4-core A53 @ 1.8GHz (for OS, crypto, etc.)
Middle case scenarios:
8-core A72 @ 2GHz (six cores for games, two for OS)
or
8-core Puma @ 1.7GHz (six cores for games, two for OS)
Worst case scenario:
4-core A57 @ 1.7GHz (three cores for games, one for OS)
GPU
Best case scenario:
24 GCN 1.2 CUs @ 800MHz (~2.5 Tflops)
Very good case scenario:
20 GCN 1.2 CUs @ 700MHz (~1.8 Tflops)
Middle case scenario:
14 GCN 1.2 CUs @ 650MHz (~1.2 Tflops)
Not very good case scenario:
10 GCN 1.2 CUs @ 600MHz (~800 Gflops)
Worst case scenario:
16-core Mali T760 @ 700MHz (~400 Gflops)
RAM
Best case scenario:
4GB HBM - 512 GB/s
12GB (LP)DDR4 - ~60 GB/s
Very good case scenario:
2GB HBM - 256 GB/s
8GB DDR4 - ~40 GB/s
Middle case scenario:
8GB GDDR5 - 190 GB/s
or
8GB LPDDR4 - 100-120 GB/s
Not very good case scenario:
32MB SRAM - 200 GB/s
8GB DDR3 - 17 GB/s
Worst case scenario:
4GB LPDDR3 - 30 GB/s
Obviously there's a pretty big gap between best and worst case scenarios, but that largely reflects how little we actually know about Nintendo's plans.
Regarding the people who are asking why Nintendo would use a CPU that's more powerful than PS4 and XBO but use a GPU that's less powerful than either, there's a pretty simple reason: any of the default options for the CPU would be more powerful than the Jaguar cores used in PS4 and XBO. The Puma, A72 and even A57 are all more capable cores than Jaguar are, and are typically organised in quad-core clusters, making an eight-core configuration the most likely (as a quad core wouldn't really allow them to compete at all, and a six-core config would save very little die space and cause an awkward asymmetry when it comes to cache). Even if they only went with the "not very good case scenario" for the GPU in order to reduce cost and power consumption, an 8-core A72 configuration doesn't take up that much die space and can consume very little power. There's not really a whole lot of point in intentionally crippling the CPU just to achieve a "more balanced" system.
