Performance
1.CPU speed
4 x 4.2GHz
8 x 3.6GHz
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
4.9GHz
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
✔Intel Core i7-7700K
✔Intel Core i7-9700K
Some processors come with an unlocked multiplier which makes them easy to overclock, allowing you to gain increased performance in games and other apps.
5.L2 cache
A larger L2 cache results in faster CPU and system-wide performance.
6.L3 cache
A larger L3 cache results in faster CPU and system-wide performance.
7.L1 cache
A larger L1 cache results in faster CPU and system-wide performance.
8.L2 core
0.
25MB/core
0.25MB/core
More data can be stored in the L2 cache for access by each core of the CPU.
9.L3 core
2MB/core
1.5MB/core
More data can be stored in the L3 cache for access by each core of the CPU.
Memory
1.RAM speed
2400MHz
2666MHz
It can support faster memory, which will give quicker system performance.
2.maximum memory bandwidth
38.4GB/s
41.6GB/s
This is the maximum rate that data can be read from or stored into memory.
3.DDR memory version
DDR (Double Data Rate) memory is the most common type of RAM. Newer versions of DDR memory support higher maximum speeds and are more energy-efficient.
4.memory channels
More memory channels increases the speed of data transfer between the memory and the CPU.
5.
maximum memory amount
