The three companies are AMD, INTEL, ARM
AMD - AMD's Ryzen 7 2700X processor is the latest version
Intel - Intel's Core i7-9700K
ARM - ARMv8-A (64 bit) and
ARMv7-A (32 bit)

Comparison between AMD, Intel, ARM processors.
- AMD, without question. Although, you should
consider an aftermarket cooler if you wish to overclock your CPU to
its fullest.
- Ryzen features eight cores and 16 threads, whereas Intel’s i7
doesn’t offer thread doubling like AMD
- AMD offers the better platform for motherboard
choice. Intel’s options are restrictive and somewhat elitist, which
arbitrarily raises the entry costs for Intel-based setups.
- Intel. With higher maximum clock speeds and
more performance gains, an Intel Core i7-9700K offers better
overlocking potential.
- Intel. Intel’s Core i7-9700K is the best
overall gaming CPU. The i9-9900K may outperform it in some cases,
but the extra costs overshadow the small performance delta. AMD’s
CPUs aren't as competitive at the highest level of gaming
performance.
- Intel is faster and more
powerful than ARM processors. But,
ARM processors are more mobile-friendly
than Intel processors (in most cases). ...
Intel-based Macs will so be released with Apple's
own ARM processors, while we've seen some great
things coming from Microsoft.
- ARM processor features
include Load/store architecture, An orthogonal instruction
set,Mostly single-cycle execution, Enhanced power-saving design, 64
and 32-bit execution states for scalable high performance,hardware
virtualization support.
So in the above comparison we have seen the main things because
of which we can state the main upgrades we need in that particular
field.
They are as follows :
- In AMD processors the organization should keep an eye for
upgrading the following features :- Threads, Motherboard Choice,
Cores, Cooling System.
I have given these names because AMD processors are already so
powerful in this specifications .
2. Intel. With higher maximum clock speeds and
more performance gains so the organization must do a upgrade
whenever it is necessary in this field
3.Intel processors are the best processors in terms of Gaming
Zone, so there must be a upgrade whenever required in the field of
gaming area.
4.Arm processor is having the widest range of devices from
sensors to servers , so there must be an upgrade in the following
field for future perspective.
