Octa-core and quad-core have the following differences:
< br >
1. Different power consumption
< br >
Four-core power consumption is generally lower than eight-core power consumption.
< br >
Octa-core power consumption is generally higher than quad-core power consumption.
< br >
2. Different threads
< br >
< br >
The octa-core has 16 threads.
< br >
3. Level 3 cache is different
< br >
Generally, the four-core three-level cache is 8M.
< br >
The octa-core is 16M.

Other similar types:

1. Dual and quad-core
< br >
The quadcore consists of two double nuclei, each of which shares 4M L2.
< br >
From a theoretical point of view, when both are not fully loaded, the results should be little different. When both sides reach full load at the same time, the quad-core should perform twice as well as the dual-core.
< br >
The maximum increase of physical quad-core relative to physical dual-core is about 80%, and the maximum increase of super-threaded quad-core relative to physical dual-core is about 40%, and the difference in the increase of the two is about twice.
