6 X 2.8GHZ

6 x 3.000 2 The speed of the central processor indicates how many processing cycles per second the processor can perform, taking into account all its cores (processors). It is calculated by adding the clock speeds of each core or, in the case of multi-core processors, each group of cores.

processor thread

More threads result in better performance and better multitasking.

turbo clock speed

4. 6GHz

When the processor is running below its limits, it can jump to a higher clock speed to increase performance.

Has unlocked multiplier

✖Intel Core i5+8400

✔Intel Core i5-9600K

Some processors come with an unlocked multiplier and are easier to overclock, allowing for better performance in games and other applications.

L2 Cache

More L2 scratchpad memory results in faster results in CPU and system performance tuning.

L3 cache

More L3 scratchpad memory results in faster results in CPU and system performance tuning.

L1 cache

More L1 cache results in faster results in CPU and system performance tuning.

L2 core

0.25MB/core

0.25MB/core

More data can be stored in L2 scratchpad for access by each processor core.

L3 core
