Performance
1.CPU speed
8 x 3.9GHz
6 x 3.7GHz
The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
2.CPU threads
More threads result in faster performance and better multitasking.
3.turbo clock speed
4.5GHz
4.7GHz
When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
4.Has an unlocked multiplier

i7-8700K
- The i7-8700K is more power efficient and generates less heat.
- The i7-8700K has a higher turbo clock boost. Turbo Boost is a CPU feature that will run CPU clock speed faster than its base clock, if certain conditions are present. It will enable older software that runs on fewer cores, to perform better on newer hardware. Since games are software too, it is also applicable to them.
Ryzen 7 3800X
- The Ryzen 7 3800X has higher Level 2 Cache. Data/instructions which have to be processed can be loaded from the fast L2 and the CPU does not have to wait for the very slow DDR RAM
- The Ryzen 7 3800X has higher Level 3 Cache. This is useful when you have substantial multiprocessing workloads, many computationally intense simultaneous processes. More likely on a server, less on a personally used computer for interactive desktop workloads.
- The Ryzen 7 3800X has more cores. The benefit of having more cores is that the system can handle more threads. Each core can handle a separate stream of data. This architecture greatly increases the performance of a system that is running concurrent applications.
- The Ryzen 7 3800X has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.
- For some games, a cpu with a higher clock speed, or in a technical name IPC (Instructions per clock), has better results than other CPU’s with higher core count and lower core speed.
- The Ryzen 7 3800X has a smaller process size. The faster a transistor can toggle on and off, the faster it can do work. And transistors that turn on and off with less energy are more efficient, reducing the operating power, or “dynamic power consumption,” required by a processor.

Performance
1.CPU speed
8 x 3.9GHz
6 x 3.7GHz
CPU speed indicates how many processing cycles per second a processor can perform, considering 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.
2nd processor thread
More threads result in better performance and better multitasking.
3.speed turbo clock
4.5GHz
4.7GHz
When the processor is running below its limits, it can jump to a higher clock speed to increase performance.
4. Has unlocked multiplier
✔AMD Ryzen 7 3800X
✔Intel Core i7-8700K
Some processors come with an unlocked multiplier and are easier to overclock, allowing for better performance in games and other applications.
5.L2 Cache
More L2 scratchpad memory results in faster results in CPU and system performance tuning.
6.L3 cache
More L3 scratchpad memory results in faster results in CPU and system performance tuning.
7.L1 cache
More L1 cache results in faster results in CPU and system performance tuning.
8.core L2
0.5MB/core
0.
25MB/core
More data can be stored in the L2 scratchpad for access by each processor core.
9.core L3
4MB/core
2MB/core
More data can be stored in L3 scratchpad for access by each processor core.
Memory
1.RAM speed
3200MHz
