i5-8400
- The i5-8400 has higher Level 3 Cache. This is useful when you have substantial multiprocessing workloads, many computationally intense simultaneous processes.
More likely on a server, less on a personally used computer for interactive desktop workloads. - The i5-8400 has more cores. The benefit of having more cores is that the system can handle more threads. Each core can handle a separate stream of data. This architecture greatly increases the performance of a system that is running concurrent applications.
- The i5-8400 is more power efficient and generates less heat.
- The i5-8400 has a smaller process size. The faster a transistor can toggle on and off, the faster it can do work. And transistors that turn on and off with less energy are more efficient, reducing the operating power, or “dynamic power consumption,” required by a processor.
i7-4790
- The i7-4790 has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.
- For some games, a cpu with a higher clock speed, or in a technical name IPC (Instructions per clock), has better results than other CPU’s with higher core count and lower core speed.

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.

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. nine0007

4 (+5%) 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. nine0007
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. nine0007
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. nine0007

Performance
| Cores The total number of physical cores. nine0052 | 6 | 4 |
| ThreadsNumber of threads. The number of logical processor cores that the operating system sees. | 6 | 8 |
Multi-Threading Technology With Intel’s Hyper-threading and AMD’s SMT technology, one physical core is recognized by the operating system as two logical cores, thereby increasing processor performance in multi-threaded applications. nine0052
| Missing | Hyper-threading (note that some games may not work well with Hyper-threading, for maximum FPS you can try to disable the technology in the BIOS of the motherboard). |
| Base frequencyGuaranteed frequency of all cores (P-cores in case of corresponding architecture) of the processor at maximum load. It is important to remember that speed and frequency are not directly related. For example, a new processor at a lower frequency may be faster than an old one at a higher one. nine0052 | 2.8 GHz | 4 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 low-threaded loads, due to which performance is noticeably increased. It may depend on the nature of the load, the number of loaded cores, temperature and the specified limits. Significantly affects the speed in games and applications that are demanding on the frequency of the CPU, but do not load all threads. nine0052
| 4 GHz | 4.4 GHz |
| BCLK System bus frequency. Some motherboards allow you to achieve a good performance boost by slightly raising the bus frequency. Often this has a bad effect on the stability of the system. | 100 | 100 |
| CPU multiplier. The final CPU frequency is determined by the simple formula BCLK * CPU multiplier. Modern processors instantly change the multiplier of each of the cores, taking into account the type of load, temperature, consumption and settings in the BIOS. nine0052 | 28 | 40 |
TDPThermal Design Power is an indicator that determines the heat dissipation in standard operation. The cooler or water cooling system must be rated for a larger value. Remember that with a factory bus or manual overclocking, TDP increases significantly. |
65 W | 88W |
| tCaseMax Permissible IHS (heat spreading plate, «cover») temperature. | 72 °C | 72 °C |
Cache and RAM
| L1 Cache First level cache. Modern processors use a multi-level cache. The first is the fastest, but the smallest. In the case of an L1 access and a miss, the L2 cache is searched for the next stage. | 64K (per core) | |
| L2 Cache Second level cache. Holds more data, but is slower. | 256K (per core) | 256K (per core) |
L3 Cache L3 cache. AMD created the Ryzen 7 5800X3D with a record-breaking L3 volume, which reduced the requirements for memory frequency and significantly increased the number of frames in many games. nine0052
| 9MB (shared) | 8MB (shared) |
| Maximum RAM Amount of RAM that can be installed on a motherboard with this processor. | 64 GB | 32 GB |
| Supported type of RAM The type of RAM depends on its frequency and timings (speed), availability, price. nine0052 | DDR4-2666 MHz Dual-channel |
DDR3-1600 MHz Dual-channel |
| RAM Channels The multi-channel memory architecture increases data transfer speed. On desktop platforms, two-channel, three-channel and four-channel modes are available. | 2 | 2 |
Video core
Integrated graphics core Allows you to use your computer without a discrete graphics card. The monitor is connected to the video output on the motherboard. If earlier integrated graphics made it possible to simply work at a computer, today it can replace budget video accelerators and makes it possible to play most games at low settings. |
