Hi,
I'm writing ARM64 ASM and testing on Apple M1 and Graviton2 N1
devices. This, however, is not a good spread of micro-architectures
among commonly used ARM64 devices. Additional micro-architectures
which I would like to test are 'High Efficiency' A53 and A55; 'high
performance' A72, A73, and A77, and 'Prime' X1.
I’m in favor of buying some ARM hardware for that as well as for FATE
maybe.
I've identified the following devices along with the
micro-architectures they use and a price estimate:
- NanoPi M4B, Rockchip RK3399 (A53/A72) - 99 EUR
& Extras (~23 EUR)
- ODROID-N2+, Amlogic S922x (A53/A73) - 71 EUR
The above should be totally ok,
- OnePlus 9, Snapdragon 888 (A55/A77/X1) - 799 EUR
for this well it’s not cheap, maybe someone has an alternative idea or
even some hardware to donate that covers some of the cores?
As a note, the cheapest Snapdragon 888 devices were phones rather than
development boards (with the 'official' development board being more
than double the example given here). I don't think the OnePlus is the
cheapest, but seems like it would be the most reasonable to test
(unlocked boot-loader, etc).
I am preemptively requesting reimbursement for these devices,
suggestions welcome.
