You don't remove a GPU while playing a PC game, you also don't revert your PS4 Pro back to a standard PS4 during gameplay. The Switch can be docked/undocked at any time during gameplay. I don't agree with all Bonzo says, anything related to simply code (such as rendering resolution, shaders, refresh rate, Anti-Aliasing, Reflections) can be edited easily. It doesn't have to run the exact same code for both versions, there can be branches that make changes to graphics rendering. Swapping textures and certain other assets would pose a number of obstacles, but that too is not impossible.

But he's right that it having to run in a 150GFlops Handheld mode will affect the docked version of the game to some extent.

Where did you get 150GF from when everyonve has it at around 300GF in handheld?

Whatever you're looking at is likely someone mistakenly talking about the half-precision floating point operations, according to the clock speeds released in the Eurogamer leak Switch is around 150GFlops undocked, 400GFlops docked. Its an underclocked Tegra X1 which is a 0.5TF chip. 

Here's the neogaf thread on the Eurogamer leak if you want to read through: http://www.neogaf.com/forum/showthread.php?t=1326373

The Eurogamer leak has been debunked and for over month now at best it was outdated information of an early devkit EG themselves said they had the information for months before releasing it, the Foxconn leak and developer dump are the most legit leaks backed by official details we know they have the platform at around 500GF docked and 300GF portable at 32, at 16 the developer dump has the platform at 1TF.

Both leaks have their issues, the Foxconn leak for example while getting a hell of a lot right also claims a 4g version, which may pan out. But they also claim there is an "advanced" switch that Nintendo have produced 2000 devkits of, a version that is apparently "more powerful than the ps4 pro."

We'll hopefully find out in a couple of weeks either way. There's a lot of skepticism surroudning the foxconn leak, Eurogamer hasn't been debunked.

I also think that a lot of people are mistaking because they simply take the numbers and say "oh, it's a lot bigger than the Eurogamer leak", when in fact the Eurogamer leak talked about big numbers, but also a massive downclocking. If I remember correctly, Eurogamer talked about 1TF, but downclocked to ~400 gflops.

And people using the latest NVidia Shield explained that this downclocking is real.

They said the Tegra X1 in the Switch when docked is downclocked from 1ghz (512 GFlops) to 768mhz (393GFlops).

The Foxconn leak says it's clocked at 921mhz (471GFlops) when docked.

I'm not exactly sure where the Foxconn leaks says it would be 300GFlops undocked though like Wyrdness says, nothing in the leak I found talks about the undocked performance.

Both leaks have issues but only one is backed by official details and confimations some of which are impossible to guess so that by far makes it far more reliable especially when EG confirmed themselves the info they had was months old.

The 300/500 part comes from the leaked developer dump which itself is backed by the video of the early released Switch unit which was confiscated but also from developers who have confirmed it, the leak had Switch at 1TF which is most likely 16 which would put the platform at 500GF when at 32, both of of these leaks have confimations behind them EG does not which puts them way above the latter in being more legit.

With many of these consoles official specs aren't available, not just the Switch. For instance, I've seen people say the Vita has only 14 gflops, that it has 28, and that it has 51. Whichever it is, those gflops would not be comparable to the gflops of the switch. The Tegra X1 is more efficient in certain aspects than the PS4 and XB1. So even in the best case Vita scenario and worst case Switch scenario the Switch ends up being significantly more than 3x as powerful as the Vita even when undocked. And if the Undocked gflops are about the same for the Wii U and the Switch, that also gives a pretty big advantage to the Switch.

Even going by the worst leaks, Switch has a much faster CPU, more and superior ram, and a better GPU in all modes, than the Wii U.

A lot of the confusion about the switch's Gflops seems to come from people confusing the f16 and f32.

Capcom said looking for porting re engine on Switch and would make AAA games...

http://nintendoeverything.com/switch-dev-talk-50000-yen-for-a-kit-capcom-wants-to-make-aaa-games-much-more/

Shield K1 with 192 kepler cores have 240 GFLOPS fp32... How some people can think Switch have less with 256 maxwell cores ?

Switch have better OS for games, Vulkan API, right for the true ue4 (not portability version)

It could be compatibility with HDR like shield TV !

Don't forget portable mode is 720p And don't need the same AA like on TV...

Switch use a APU tegra customised, could have spécial ram like EDRAM or HBM... Nobody can say exactly what Switch is capable...

Wait and see... Don't make a opinion based the games show, it's wiiu games like titanfall 1 was xbox360 games on xboxone...
