How Will be Switch 2 Performance Wise?

Bummer on the CPU and memory allocations for the OS, but maybe Nintendo will free up resources as time goes on.

Was expecting 2GB max for OS allocation given how little Switch 1 used. Seems like their chat/networking features are more resource intensive than I would have thought.

I was hoping for 3-4GB to be honest, to fix one of the biggest annoyances with the Switch... Which was the sluggish store, UI and lack of voice chat and other features.

But in return I hoped the console would have 16GB to let it breathe.

I got half my wish.

Edit: 

It is becoming clear that the biggest bottlenecks are probably going to be the CPU, memory capacity, and memory bandwidth, in that order. Mostly because bandwidth can be mitigated by DLSS, capacity can be mitigated with lower resolution textures and lower quality RT, but the CPU doesn't really have much to scale unless you can off-load CPU heavy tasks on the GPU or you have some sort of dynamic power management where the CPU can clock higher at certain points but with the cost of GPU power-consumption (and performance.) 

Bandwidth will likely be the first bottleneck, followed by the RAM capacity.

Remember Nintendo has leveraged nVidia's ability to add some extra hardware blocks to allow the CPU to do less work.
I.E. Hardware decompression and Ampere is pretty good at GPU compute, so there are tasks it can do there, especially as it seems to have an extra abundance of GPU compute available, more so than anything else.

In retrospect:

3X in Ram Capacity for Games.
3.1Xin Ram Bandwidth.
10X increase in GPU FP32 compute if we take the lowest portable clocks. (Other aspects like improved RT, DLSS, Improved Delta Colour Compression, Culling, Polymorph and more also give it a big edge.)

The CPU is probably one of the least of my concerns to be fair.
A57 per-core performance is 222 points in GB5 verses 918 for the A78C.
Normalizing clocks per core it's 123.33​ for the A57 305.93​ for the A78C.

So basically 2.5x the performance per core.

....Then they went ahead and double the amount of cores available for games from 3 cores to 6 cores.

It's actually pretty good.

Is it Zen3 @ 3.8Ghz good? Not a chance. But I am still happy with where the performance should fall for the CPU.
