Switch 2 battery to last 4 hours and why AMD lost out

Seems AMD was in the running for the switch 2 but lost the bid do to efficiency of their chips and wanting to force Nintendo into 15watt performance, but Nintendo wanted 5watts. They also state that the battery in the switch 2 is slightly better than switch 1 because the new chip is more efficient. So we could be looking at 4 hours of time now.

Might explain why OLED is missing also. 5 watts sounds very low for switch 2 unless that chip is magical!

As reported by a new video shared by Moore's Law is Dead, AMD lost the bid due to its chip's performance and efficiency at 5 watts. The company reportedly wanted Nintendo to push the system in handheld mode at up to 15 watts to get truly next-generation performance, but the Japanese company didn't want to push its console that far, as they didn't want to have a heavier battery. Ultimately, NVIDIA's chip provided the same power as the AMD chip with much better efficiency and a far cheaper node, which was very important for Nintendo to keep costs low.

Battery life is likely to be one of the highlights of the Nintendo Switch 2. Judging from last week's leaks, the battery should provide around 20 wh, a slightly higher capacity than the original Switch battery. However, the system will consume way less power in handheld mode than its predecessor, granting much better battery life than the current generation console.

Unless the Switch can harness the power of an M series Apple chip, there's going to be an expense for the battery to last that long with it being 5watts. Handheld mode is going to be rough, but I wonder how it will handle being docked.

Just like Intel supposedly being in the running for PS6 but losing out, the winner for the Switch 2 was almost undoubtedly going to be Nvidia just like the winner for the PS6 was undoubtedly going to be AMD. Sometimes companies have more of a competition for it to keep everyone honest and get themselves the better deals, with their prime candidate knowing other major companies are in the running.

You might have x86/ARM, but for full compatibility the same company is still the most surefire bet, especially where using bespoke graphics APIs like NVN.

4 hours is impressive?

I believe it's more backwards compatability then battery life. Sounds like switch 2 is not going to be that much more powerful then the switch like to switches slapped together. They could of gone with amd for there handheld and could of used or could of done a custom made Ryzen z1 extreme with upcoming z2 features with FSR 4 rumored to also have Ai upscaling. Ryzen is already or presumed to ha e 8.4tf of power which not only makes it more powerful then ps4 pro but series S aswell

Thank fuck Nintendo went with nVidia. Switch 2 would be a fucking disaster on an AMD SoC.

You've got it backwards. It sounds like AMD was shopping them some Z1 derivative on TSMC 4 or 5nm, but they went with a much older and weaker design on a bigger old ass node (probably Samsung 8nm) cause it performed the same at 5W miser mode, but is likely many many times worse than the AMD part would have performed at 15W.

Switch isnt 10 years old is it. I thought Nintendo Signed up to a 10 year deal with NVIDIA, but I guess that means they will supply the chip for ten years and doesnt lock them into the next model.

5 Watts seems like nothing.

5 Watts doesn't sound too hot.

Still holding out hope for an oled model, because if not I'll just wait think. My deck OLED is serving me more than fine and by the time the switch 2 OLED appears there will be a big batch of new games I can buy with it.

The original Switch consumed ~8.9W in handheld mode at max brightness (~7.1W min brightness), so accounting for the other elements (memory, storage, screen etc.) the APU was also probably taking up about 5W. In the best case, we should expect Switch 2 to be slightly slower than the Steam Deck in the handheld mode. It can be faster docked.

Other people have done the math and found that T239 would hit the voltage floor at 8nm at mobile TDPs, so Nintendo would have been better off from a performance and cost perspective shipping a smaller APU. The GPU they are using is about 50% bigger than Steam Deck's with 3x more ALUs.

Also 8nm probably isn't going to be available for the lifetime of the Switch 2, so it isn't such a cost saving if you have to redo the exact same work on a newer process anyway.

Mmmmmh…. Not sure about that, Nintendo wanted the cheapest possible chip and to pack the smallest and cheapest battery they could.

4 hours battery life is nothing to shout about… but eh we will see.
Yep, and this also means Nintendo will run very low clocks in handheld mode which doesn’t bode well for performance.

In what way? AMD is overall comparable to Nvidia in the mobile in terms of feature set.
Does AMD have DLSS 3.6?

That is why to choose Nvidia over AMD for a lower powered console that wants moonshot ports from current gen. Upscaling can do most of the heavy lifting. Nintendo genius sticking with Nvidia, only a marketing person would swap to AMD, or someone who doesn't understand what gamers want.

Most of his Switch 2 rumors match what everyone else is currently saying when he said it nearly a year ago. Cut him some slack on this at least. Of course taking this with a grain of salt as one should.

Compared to less than an hour you get with the PC handhelds at 15w. Even Steam deck gets you two at best and they have much bigger batteries. The more powerful these handhelds get, the more battery they consume. Miss the Gameboy days of 10+ hours on 2 AA batteries.

If true, on every level Nvidia's chipset is better. Equal power at lower wattage is saying a lot as the Hz rate difference would be huge going from 5w to 15w. Of course like with the Switch most likely a dev could increase that if they wanted to. Super Mario Odyssey runs at a higher wattage than most games on the Switch.
