All we know from first CPU to the latest high end CPU models. all CPUs has instruction sets and some important Units inside.
In a cpu most important parts are
* Control unit (Control LOGIC)
* Arithmetic logic Unit (ALU)
* Floating Point Unit (FPU)
* Data Paths
* Caches Layer1 and layer 2
In ancient times there was a CPU 80386SX we were running computer with it.
if we insert intel Math Coprocessor(80387) to board it was working 2-8 times faster with some software.
Same time we used to insert layer 2 memory to board it was working 2 times faster with reading and writing data.
Datapaths also changed. 32bit paths became 64 bits.
if you are wanting to buy processors you must know its FPU count, L1 and L2 caches count, ALU count. Memory accessing paths counts per core.
Today there is some cpus with 8 cores. but their cores dont have one FPU per core. 8 ALU inside and 4 FPU inside. Also memory paths has the same problems. their 16 core is beaten by other company's 4 core processor.
Please make compter race to see real values of products. Is it necesarry or is it time killer chip? Make tests.
