@Markoctal-core NVIDIA Carmel ARMv8.2 CPU
For the ARM gurus, before I make a fool of myself, how recent is this core ? and on what process node ? It looks like 12nm. First tested Sept 2018, so should be more recent than Rome.
But how fast is it compared to some you have been mentioning here ?
Carmel is on par with Cortex A75 give or take.
I already did point out, that if you want the most recent ARM core (a Cortex A76, mind you?), which can run Linux (as part of WSL) out of the Box, it would be the Surface Pro X. All newer Cortex A CPUs are only available in Phones as of today.
Also of note is, that ARMv8.x refers to the ISA revision, not necessarily to a particular implementation. A higher ISA revision typically means, later versions supporting more instructions.
For example A76, A77, A78 and AX are all ARMv8.3 compliant.
