Performance

1.CPU speed

6 x 3.5GHz

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

4.7GHz

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

✔Intel Core i7-7800X

✔Intel Core i7-8700K

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

1MB/core

0. 25MB/core

More data can be stored in the L2 cache for access by each core of the CPU.

9.L3 core

1.3MB/core

2MB/core

More data can be stored in the L3 cache for access by each core of the CPU.

i7-8700K
  • The i7-8700K 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 i7-8700K 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.
  • 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 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.

1. Oscher 9000

6 x 3.5GHz

6 x 3.7GHz

CPU speed indicates how many processing cycles per second a processor can perform, given 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

4.7GHz

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

4. Has unlocked multiplier

✔Intel Core i7-7800X

✔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

1MB/core

0.25MB/core

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

9.core L3

1.3MB/core

2MB/core

More data can be stored in L3 scratchpad for access by each processor core.

Unknown. Help us offer a price. (Intel Core i7-7800X)

DDR (Dynamic Dynamic Random Access Memory, Double Data Rate) is the most common type of RAM. New versions of DDR memory support higher maximum speeds and are more energy efficient.

4 memory channels

More memory channels increase the speed of data transfer between memory and processor.

5.Maximum memory

Maximum memory (RAM).

6.bus baud rate

The bus is responsible for transferring data between different components of a computer or device.

7. Supports Memory Error Code

✖Intel Core i7-7800X

✖Intel Core i7-8700K

Memory Error Code can detect and repair data corruption. It is used when necessary to avoid distortion, such as in scientific computing or when starting a server.
