General info

1.Supports 64-bit
Intel Core i7-8700K
Intel Core i7-9700K
A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit apps.
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.
3.GPU clock speed

350MHz

350MHz

The graphics processing unit (GPU) has a higher clock speed.
The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.
Peripheral Component Interconnect Express (PCIe) is a high-speed interface standard for connecting components, such as graphics cards and SSDs, to a motherboard. Newer versions can support more bandwidth and deliver better performance.
6.CPU temperature

100°C

100°C

If the CPU exceeds the maximum operating temperature then problems such as random resets can occur.

Performance

1.CPU speed

6 x 3.7GHz

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.
More threads result in faster performance and better multitasking.
3.L2 cache

1.5MB

2MB

A larger L2 cache results in faster CPU and system-wide performance.
4.L3 cache

12MB

12MB

A larger L3 cache results in faster CPU and system-wide performance.
When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
6.L1 cache

384KB

512KB

A larger L1 cache results in faster CPU and system-wide performance.

Memory

1.RAM speed

2666MHz

2666MHz

It can support faster memory, which will give quicker system performance.
This is the maximum rate that data can be read from or stored into memory.
More memory channels increases the speed of data transfer between the memory and the CPU.
The maximum amount of memory (RAM) supported.
The bus is responsible for transferring data between different components of a computer or device.
6.Supports ECC memory
Intel Core i7-8700K
Intel Core i7-9700K
Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.

Features

1.Has AES
Intel Core i7-8700K
Intel Core i7-9700K
AES is used to speed up encryption and decryption.
2.Has dynamic frequency scaling
Intel Core i7-8700K
Intel Core i7-9700K
Dynamic frequency scaling is a technology that allows the processor to conserve power and reduce noise when it is under a light load.
SSE is used to speed up multimedia tasks such as editing an image or adjusting audio volume. Each new version contains new instructions and improvements.
4.Has AVX
Intel Core i7-8700K
Intel Core i7-9700K
AVX is used to help speed up calculations in multimedia, scientific and financial apps, as well as improving Linux RAID software performance.
5.Has MMX
Intel Core i7-8700K
Intel Core i7-9700K
MMX is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
6.Has F16C
Intel Core i7-8700K
Intel Core i7-9700K
F16C is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.

Benchmarks

This benchmark measures the performance of the CPU using multiple threads.
This benchmark measures the performance of the CPU using a single thread.
