Performance

CPU speed

4 x 1.6GHz

6 x 2.8GHz

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.

CPU threads

More threads result in faster performance and better multitasking.

turbo clock speed

3.4GHz

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

Has an unlocked multiplier

✖Intel Core i5-8250U

✖Intel Core i5+8400

Some processors come with an unlocked multiplier which makes them easy to overclock, allowing you to gain increased performance in games and other apps.

L2 cache

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

L3 cache

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

L1 cache

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

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.

L3 core

1. 5MB/core

1.5MB/core

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