Performance

1.CPU speed

6 x 2.9GHz

6 x 3.2GHz

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

4.1GHz

4.6GHz

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 i5-9400F

✖Intel Core i7-8700

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

1.5MB/core

2MB/core

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

Memory

1.RAM speed

2666MHz

2666MHz

It can support faster memory, which will give quicker system performance.

2.maximum memory bandwidth

41.6GB/s

42.7GB/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

The maximum amount of memory (RAM) supported.

6.bus transfer rate

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

7.Supports ECC memory

✖Intel Core i5-9400F

✖Intel Core i7-8700

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.

8.eMMC version

Unknown. Help us by suggesting a value. (Intel Core i5-9400F)

Unknown. Help us by suggesting a value. (Intel Core i7-8700)
