Hardware Mariko memory cannot go above 1600MHz?

[willfr]

I've been talking about the Switch Pro with my friend and he insists the Mariko SoC memory cannot go above 1600Mhz, he says they'd have to make significant changes to the SoC to go above 1600... is this true? I hope this isn't true because that probably means the Switch Pro (or whatever they decide to call it) will be stuck at 1600Mhz

I would imagine a Switch pro would have a new SoC

Didn't sciresM say that's not happening though? It's still gonna use Mariko

I have no idea what you "friend" means with "memory".
But every switch is currently (theoretically) capable of 1.7Ghz /clockspeed/.
[The switch is underclocked by default]

(Memory is 3GB btw, that is available to devs at most).

Not sure what you hombre is talking about...

Also what Nerdtendo said.
Nothing would keep Nintendo from using another component, for as long as backwardscompatibility can be achieved.

Scires M doesn't work at Nintendo. Anything anyone says is speculation.

The EMC currently tops out at 1600Mhz, it can go down to 1331Mhz too

He is referring to the speed of the system RAM not the CPU.

so "pro" only upgrade mini oled without new soc lol, no reason to exist then
i think new tegra orin based on ampere gpu, will replace mariko for "pro" version can uplift to 1440p and scaling with dlss to 4k

They can increase the CPU and GPU clocks a lot with Mariko, especially if they do a further die shrink. But I'm wondering if the EMC is stuck at 1600Mhz, that could be a real problem for docked mode (according to digital foundry and other experts). If you don't or rarely play docked, then 1600Mhz probably won't be a problem

Nah 1600 is the max speed for mariko EMC

A further die shrink wouldn't be Mariko then.

Is it realistic to think they could increase it for a revision or would that require significant changes?

It's plausible that it could be increased, considering it was a decrease from erista

What??? Erista's EMC could go above 1600Mhz??

tegra x1 has memory speed 3200mhz, looks like nintendo only using half of that
og lpddr4 vs mariko lpddr4x its downspeed to match og switch and gpus 26% faster, but we all know, they downspeed to achieve for better efficiency
og has 512 gflops(1000mhz) vs mariko 650 gflops(1267mhz)
imagine if they unlock limit to maximum performance on mariko, then you can play 60 fps in most games 768 mhz vs 1267 mhz (+65% bump)

I see, when they Erista and Mariko, to refers to the Tegra SoC not the Switch revision. It looks like the RAM can operate in either 1331 or 1600MHz. Is one for portable and the other for docked mode?

yes, they can choose either 1331 or 1600 for docked, but only 1331 is available to portable modes
