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 i5-9400
✖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.

Performance in games and similar applications, according to our tests.
The performance of 4 cores, if any, and performance per core has the greatest impact on the result, since most games do not fully use more than 4 cores.
The speed of caches and working with RAM is also important.
Office speed

Core i5-9400
73.7
Performance in everyday work such as browsers and office programs.
The performance of 1 core has the greatest impact on the result, since most of these applications use only one, ignoring the rest.
Similarly, many professional applications such as various CADs ignore multi-threaded performance.
Speed in heavy applications
Core i7-8700
51 (+11%)
Core i5-9400
45.4
Performance in resource-intensive tasks loading a maximum of 8 cores.
The performance of all cores and their number has the greatest impact on the result, since most of these applications willingly use all the cores and increase the speed accordingly.
At the same time, certain periods of work can be demanding on the performance of one or two cores, for example, applying filters in the editor.
Data obtained from tests by users who tested their systems with and without overclocking. Thus, you see the average values corresponding to the processor.

Different tasks require different CPU strengths. A system with few fast cores and low memory latency will be fine for the vast majority of games, but will be inferior to a system with a lot of slow cores in a rendering scenario.
We believe that a minimum of 4/4 (4 physical cores and 4 threads) processor is suitable for a budget gaming PC. At the same time, some games can load it at 100%, slow down and freeze, and performing any tasks in the background will lead to a drop in FPS.
Ideally, the budget shopper should aim for a minimum of 4/8 and 6/6. A gamer with a big budget can choose between 6/12, 8/8 and 8/16. Processors with 10 and 12 cores can perform well in games with high frequency and fast memory, but are overkill for such tasks.
Also, buying for the future is a dubious undertaking, since in a few years many slow cores may not provide sufficient gaming performance. When choosing a processor for your work, consider how many cores your programs use. For example, photo and video editors can use 1-2 cores when working with filtering, and rendering or converting in the same editors already uses all threads.
Data obtained from tests by users who tested their systems both with overclocking (maximum value in the table) and without (minimum). A typical result is shown in the middle, the more filled in the color bar, the better the average result among all tested systems.
Benchmarks
Benchmarks were run on stock hardware, that is, without overclocking and with factory settings. Therefore, on overclocked systems, the points can noticeably differ upwards. Also, small performance changes may be due to the BIOS version.

For example, a new processor at a lower frequency may be faster than an old one at a higher one. 3.2 GHz 2.9 GHz Turbo frequencyThe maximum frequency of one processor core in turbo mode. Manufacturers allow modern processors to independently increase the frequency of one or more cores under heavy load, due to which performance is noticeably increased.
