"Parker" is a new SoC based off of the newer Pascal architecture. Nintendo's SoC for the Switch is labeled as a
"custom Tegra processor" by Nvidia. It is not a TK1, TX1, or "Parker." It is another Tegra variant that may also be based off of the new Pascal architecture. Its specs and chip setup will likely be a bit different from what we would expect, and the memory system would be one of the attributes that Nintendo would pay close attention to.
It's probably too hard for some people to understand that the Switch SoC is a custom design built for a gaming system as opposed to pulling off the shelf parts and sticking it inside a tablet.
Some people think it will be poor as a portable because it will throttle and lower performance to conserve battery power. It's weird that, we know that Nintendo would be setting constraints to get the CPU, GPU, RAM to run at a certain Wattage so that they can get a decent battery to work with.
Someone uttered in the same sentence that the Switch is as powerful as a Wii U and is only getting a custom design to be power efficient. That's silly, we know the Tegra X1 is very capable compared to the Wii U and the Switch having a custom SoC correlates with NateDrake mentioning how it's going to have Pascal Architecture which correlates to having a 16nm GPU and most likely CPU. What I'm getting at is, there are two main factors to make a chip have low power consumption, that is design, and die size.
Anyway, I don't know what the fuck happened the last couple of pages. Most people in here have reasonable expectations with what you can get out of what technology with all the info we have so far.
That's why assuming the Switch SoC has a 16nm GPU and looking at the performance of Tegra X1 and Parker. It's not unreasonable to at least see as minimum the Switch being twice as strong as a Wii U in FLOPS.
So 352 GFLOPS as a minimum in portable mode, that is less than Tegra X1 but with 16nm compared to 20nm and a new design, it would easily be more power efficient compared to a Tegra X1 down clocked at the same performance.
But apparently those minimum expectations are too insane for Nintendo to have including having a 128-bit bus to have LPDDR4 RAM to give 50GB/S bandwidth.
Nintendo are apparently still in arrogant mode, they got Nvidia to make a Turbo Vita, 40 GFLOPS here we go!
