How The Switch 2 Could Do 4K@120fps

Well, no node is mentioned, but considering it's only supposed to come out next year, 7nm would be pretty much the minimum, if not even 5nm or any variation of and in between those two.

On the other hand, it's pretty clear why the TDP is so large: 12 core CPU based on the A77, and while no clock speed or GPU details apart from being next gen are detailed, the bandwidth target of 200 GB/s is 50% higher than on Xavier's top-end chip, which means the GPU will get even bigger and probably reach close to 1650 size - and performance.

For comparison's sake, what's in Xavier is pretty much right in between the MX250 and MX350, both in size and performance, and those draw already about 20W, which leaves 10W for the 8-core Carmel CPU if it stays within it's 30W target.

@bolded: yeah, in Laptops, which have a much higher TDP as they can dissipate heat easier through the keyboard and have more space for a larger battery. And even then, to hold those clock speeds necessary to beat the PS4, they still need to use H chips, the 15W U chips are not enough. Ryzen 4000 U-series could change this, but we'll have to wait for tests of those.

Well I think realistically in docked mode a Switch 2 could possibly get away with pulling 20-30watts if they actually go with a magnesium alloy frame(which would help dissipate heat). The current Switch is about as thick as the new Suface Pro-X and that sports the SQ1 putting out 2.1 Tflops @ 20w max. So the possibilities are there but many factors would determine what they could put into this system, such as the consoles material build.

But of course it wouldn't need max power draw in handheld mode and something closer to current Switch's pull of 7-8w total would be more than enough. Especially with techniques like DLSS and VRS on a smaller 1080p screen, image quality would look pretty amazing and most wouldn't notice the visual imperfections and artifacts as much since they aren't blown up in size...

But wouldn't that make taking the Switch out of the dock risky? I mean, that should get pretty hot like this...

As for the Surface Pro-X, again, try giving that one consistent high load. 2.1TFlops are it's peak performance, but it's far from holding those under full load. Case in point: It's supposed to be at 2.1 TFlops, but it's graphics score just edges out the UHD 620 in Intel 8250U laptops in 3D Mark's Night Raid graphics benchmark and get's easily beaten by a Vega 8 in a Ryzen 5 2500U despite the latter only claiming 1.1 TFlops.

In other words, the SQ1 at ~7W wouldn't do much better than the Tegra, if at all.
