Re: Raspberry Pi 4 Thread - general discussion

Does that mean the SOC can address 24 GB ? There may be an off by one error in my math and there are probably no suitable packages with 24 GB available so let's say 16 GB would be possible? 24GB would be 8 of those 3GB DDR's in the iPhone X or 6 x 4GB chips from the Pi4B4. No room on the PCB to pla...

Re: RISC OS Pi?

Well if you have a 64bit version of RiscOS I would be happy to move to it.

Soon?

I believe Free Pascal is nearly working in it.
I don't use C if I can help it these days, mostly Ultibo which is FPC based.

Re: Should I wait for the next revision of the pi 4

I saw those xrays pics but silicon seemed transparent, hard to detect the die sizes. Going form 28nm to 16nm will triple the number of die on a 300mm wafer. If the Pi4 is so successful that more chips are needed we may get a revision. I have no idea of the capacity of a modern 300mm 28nm FAB. But 28...

Re: The Great Raspberry Pi Computers.

And the ARM cores are becoming bigger than Videcore these days. So next shrink to 16nm and we get two VC6s? In 28nm the VC6 is smaller than the VC4 = faster? How big is the L2 cache?

Re: RPi4 minimal SD card size

I have used 128 and 256MB cards on all the other Pi's.
Perhaps I need to test them on this Pi4.
Those older cards(found in old mobile phones and MP3 players)are SLC, single layer flash cells.
SLC should be more reliable.

Time to try.

I don't doubt somebody could make a better Pi0, after all there are full x86 computers the size of a full size SD card. The issue however, would be producing it and selling for a profit at the current price. Well the BCM2708 is made in 40nm, eventually the fab will stop making them? A dual core A32...

That will probably get fixed soon.

Then Pi4 does become closer to a replacement desktop for me.
