How Will be Switch 2 Performance Wise?

Well it is a bottleneck.  Especially for fps and resolution.  That is just kind of a fact. 

If Remake (making up numbers) is at 70 gb/s at 30 fps with the S2's ecosystem...  double fps requires double memory bandwidth and the S2 doesn't ha e 140 gb/s.

At this point there is no doubt it is a bottleneck.  Remember the quote where games on the Series S at 60 fps should port over at 30 fps?  Series s is over 2x the memory bandwidth, hence ports of 60 to 30 should work.  

That's not how it works.

There are numerous factors in overall performance from pixel fillrate to texel fillrate to CPU draw calls to polygon rasterization; memory bandwidth is only one element of many.

If Switch 2 had double the bandwidth, it probably still wouldn't get to 60fps on something like FF7 Remake cos it would still be limited by things by other factors like polygon counts or draw calls.

You want to think 102 gb/s isnt a bottleneck, go ahead.  You are wrong.  There is a reason the Halo Strix is going after 256 gb/s. 

Perma argued with me over this, post launch even he has made comments that 102 gb/s will limit fps and resolution because it will.

And yes, within an ecosystem of hardware doubling fps requires double bandwidth.

Frame per SECOND 

Gb per SECOND 

Memory bandwidth significantly affects frames per second (FPS) in gaming and graphical applications, as it determines how quickly data can be transferred between the GPU and its memory.

Understanding Memory Bandwidth

Memory bandwidth refers to the rate at which data can be read from or written to memory by the processor, typically measured in gigabytes per second (GB/s). Higher memory bandwidth allows for more data to be processed in a shorter amount of time, which is crucial for maintaining high FPS in demanding applications.

Impact on FPS

1. Bottlenecks: When memory bandwidth is insufficient, it creates a bottleneck, preventing the GPU from receiving data quickly enough to render frames efficiently. This can lead to stuttering, inconsistent frame times, and lower overall FPS, especially in graphically intensive scenarios like high-resolution gaming or applications utilizing ray tracing. 

Sure it computing is complex, but claiming 102 gb/s isn't going to limit fps is nonsense.
