When you said Application, you means something like Premier Pro right? CPU is better BUT recommend at least minimum of 8GB of RAM(if you open 2-3 application the same time it'll crash)
no, i mean any application on general, my Question when you assign 20GB of RAM for 16 Cores , logic says that each core will have a 1.25GB, does the CPU architecture accepts Fractures and fractions ??? (.25) , or it will not use it and will use only the 1 GB ?

Having replied to your other thread, I am copying my answer here and asking the mods to close the other one.
"First, what platform is it you pretend to have 16 cores in? Is it a server platform?
Secondly, the OS will handle all memory calls, so the 20GB will be shared on-demand by all the CPU cores. If you are running an usual OS enviroment, the OS will assign processes to threads belonging to each physical core as these processes come up. Each process will demand a certain amount of memory, that will be addressed by the OS. The 20GB will be shared as needed, not assinged to each CPU core. RAM is not divided by the CPU cores, it is shared.
If you are running a virtualization server, on the other hand, then each virtual machine may be assigned to a specific core using a set amount of memory. In that case, you will have to tailor the system to the memory footprint of the processes you want to run. Since virtualization servers are purpose-built machines, there is no general memory/core ratio, you have to understand the demand for your processes."

It seems you are not very clear on how memory is handled in a x86 enviroment. Memory is a big pool that is called upon by the OS. Any processes may request memory operations, that will be handled by the OS. How many cores the CPU has makes zero difference on how much memory you need.
You need as much memory as the programs you run demand. For usual Windows users, including gaming, 8GB is really enough. 16GB is hardly justifiable and anything above that is pretty much useless.
