Raspberry pi 3 and x86 retropie

CodeDrawer

I noticed that the 32 bit pi 2 uses the same image as the pi 3 that is 64 bit. Why are they doing this? Can the pi 3 run x86 builds?

@CodeDrawer The Raspbian kernel is 32 bit. Here's a discussion regarding it. https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=138385

@AlexMurphy so we just have to wait until we get a 64 bit kernel?

@CodeDrawer There will likely never be a 64bit Raspbian for the RPI3 (which RetroPie runs on). The Raspberry Pi has a different CPU from a PC (ARM vs x86/x86_64)

There would be no advantages either - in fact running in 64bit mode (aarch64), many emulators would be slower (as they utilise arm / neon optimisations)

Hey guys, if I build a 64 bit kernel, will I be able to get a x86 download?

I found this too it may help.

@CodeDrawer No, x86 and ARM are different architectures.

CodeDrawer

Oh, so if I made a 64 bit kernel someone would need to make a arm 64 retropie?

AlexMurphy

@CodeDrawer See Buzz's answer above.

CodeDrawer

Aww, so the pi will likely never be able to run Gamecube? Or wii?

AlexMurphy

@CodeDrawer NEVER. And I say that without an ounce of doubt. Absolutely never.

CodeDrawer

Aww. I had hopes for it! But @AlexMurphy What use is having a 64 bit computer if it doesn't run 64 bits? Isn't that a waste?

AlexMurphy

@CodeDrawer Well maybe if the next Pi clocked at 3GHz, had at least twice the RAM and a hefty GPU then, perhaps but that is as likely as my pet unicorn breeding successfully.

@AlexMurphy Comparison level over 9000

@AlexMurphy The pi foundation will keep producing 64 bit flagship models, and the 64 bit ness will seep into the other cheaper models so I don't see why not they will make a 64 bit raspbian.

@CodeDrawer i believe you can already get a 64-bit kernel for the rpi3 if you look around.

however it won't suddenly make the rpi3, or likely any near-future rpis anywhere near the spec needed to run dolphin, etc.

CodeDrawer

What are the specs to run dolfin?

@dankcushions Thanks :)
