Reading the thread it looks like an expensive Pi5....
My problem with Pi4 is surfing on the internet of today. L2 cache like 1024 kB is not much.
L3 cach like 3-4 MB and private L2 cache like 512kB.
Any CPU like A76, A77 or A78 could be OK
I am reading a test in BYTE May 1986. They are comparing 68010, 68000 and 8088 with VAX 11/780.
Real time for sieve of Erathostenes in compiled C:
Vax 11/780 .............1.7
AT&T 68010............2.4
PCXT 8088..............8.2
TRS80-16B 68000..6.0
Multitasking (1 and 6 processes)
Vax 11/780...
Is he interested in games?
I have some versions of Raspberry Pi
All of them have Python2 and 3 as standard.
There are some games with code in Python.
This is much like Basic code in the DOS age.
RPi also have C,C++ and Java.
Take a look at Rosettacode.org and find something to test!
Raspberry Pi 5 is not announced yet but what would you like to have?
I guess both ARM32 and ARM64 are demanded so X2 and X3 are not any alternatives.
How much cost and how much RAM?
Have you ever seen any Atom beating any Core i on any program?
I tested this c++ code:
long_prtimes.cpp from rosettacode.org
It goes up to 64000 but you can go to 128000 or 256000 with small changes.
My Goldmont Plus at 2.7 GHz is faster than Core i7-8700 at 4.3 GHz (64bit)
For Raspberry Pi 4...
How big are MacBook and IMac today?
No doubt they could make a better CPU than Core i7 but how much can it cost?
Volume is everything. Something like a server CPU?
I have tested all CUDA alternatives for Fedora but my Linux USB-stick is too small (only 32 GB).
So I got a 512 GB SSD as "live USB-stick" and dowloaded Fedora 31. But to make it a complete Linux is not possible. It is asking for a new HD to install. This was not the problem with the 32 GB...
I have found some interesting code for CUDA so I would like to test the nvcc with my GPU (Geforce 2070).
However my Fedora Linux want something very big dev system like 80 GB (or Nvidia want it with Fedora).
Any smaller alternatives in Linux?
OK branch-and-bound is very fast but not the same on ARM and X86_64 with gcc compiler.
With ARM (RPi 3) I have no problem with optimizing -O1, -O2 or -O3 and it works up to 18x18.
With core i7-8700 it works with 22x22 but all optimizing result in segmentation fault....
