Intel Core i9-11900KB
With integrated graphics you don’t need to buy a separate graphics card.
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.
5.CPU temperature

100°C

100°C

If the CPU exceeds the maximum operating temperature then problems such as random resets can occur.
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.
DirectX is used in games, with newer versions supporting better graphics.
OpenGL is used in games, with newer versions supporting better graphics.
9.GPU turbo

1300MHz

1450MHz

When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.

Performance

1.CPU speed

8 x 3.6GHz

8 x 3.3GHz

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.
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 i7-11700K

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

2MB

10MB

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

16MB

24MB

A larger L3 cache results in faster CPU and system-wide performance.
7.L1 cache

512KB

768KB

A larger L1 cache results in faster CPU and system-wide performance.
8.L2 core

0.25MB/core

1.25MB/core

More data can be stored in the L2 cache for access by each core of the CPU.
9.L3 core

2MB/core

3MB/core

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

Memory

1.RAM speed

3200MHz

3200MHz

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.
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.
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.
7.Supports ECC memory
Intel Core i7-11700K
