Forums - Nintendo Discussion - Switch 2 motherboard maybe leaked

Handheld: CPU 1100.8 MHz, GPU 561 MHz, EMC 2133 MHz

Docked: CPU 998.4 MHz, GPU 1007.25 MHz, EMC 3200 MHz

More specific clock-rates. If the memory clocks are per module, then we're looking at 100 GBps in docked mode (rather than 120GBps max for LPDDR5X.) Not horrible given the GPU's performance. Should expect 25 GBps per TFLOP on Ampere. After considering the CPU's share of the bandwidth, 100 GBps should be sufficient. 

CPU clocks are pretty low. 

Also the Handheld and Docked mode for the CPU seem to be swapped. Leaker confirmed that they aren't flipped. 

But overall, I am satisfied with the system's hypothetical specs. Think Nintendo and Nvidia did a good job. CPU might be a bottleneck for some ports, but maybe not if the frame-rate target is something like 30fps.

Considering how Ampere scales... maybe around 20% and 34% of an RTX 3050 for comparison purposes. The closest pieces of hardware in terms of performance would be the 8th gen consoles and the Steam Deck, as expected.

Edit - big oof on the CPU side if those are true, though. They must be using a dedicated processor for decompressing data off the SSD but even then...

Just for a comparison to the Digital Foundry simulation, the RTX 2050 they used was clocked at 735Mhz, which should be about 3.01 TFLOPs. 

These Docked GPU specs are slightly better than that (3.09 TFLOPs.)

Of course the memory setup is different, and there will be closed platform/Nintendo API optimizations. But yeah, this is the ballpark of where we should expect the non-optimized performance of games to be, unless the CPU being so lowly clocked is a huge issue. 

I do expect optimizations to go pretty far though. Only thing I am hoping for now is a VRR screen!



CPU will be the bigger challenge for developers 100%.

PS4/XBO ports should be fine, but anything from this gen that isn't already running extremely well on the console CPUs would face huge issues.



 

 

 

 

 

Apparently Microsoft Flight Simulator 2024 is heavily rumored for Switch 2. If that game can run on the Switch 2, I think most releases which tend to be far more GPU-bound than it can. 

Probably will struggle most with games that depend more on a single thread or two. 

I am also thinking this is Sammy 5nm. The handheld GPU clocks seem to be too high for 8nm given the likely battery size (and minimum viable playtime), but would fit 5nm well.

Doesn't Flight sim 24 use game streaming for some of its assists?  Ho would that work if the switch is offline?

Sure. It shouldn't be an issue. Switch 1 had quite a few cloud games.

As to the point I was making, it is still a CPU-heavy game regardless. 



I mean, MSFS24 is bottlenecked at around 120 fps in a 12900K... which has twice as many cores running three to four times faster with a higher IPC than the Switch 2's CPU (assuming those clocks hold, again).

That game will definitely be cloud-only or drastically cut back. It's already going to be always online, so the former is more likely, IMO.

How exactly would this compare to the CPU in the PS4/XBO? I assume it'd be more capable but it seems it wouldn't be by much based on what you're saying.



Seems like it'll be a lot weaker than I hoped (PS4 Pro) even though it's launching a year+ later than I expected. Perhaps modern features and optimization will push it close enough. Hopefully the base console won't cost more than $400.
