Performance
1.CPU speed
6 x 3.3GHz
8 x 3.6GHz
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
3.6GHz
When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.

i9-9900K
- The i9-9900K 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 i9-9900K 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 i9-9900K 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 i9-9900K is more power efficient and generates less heat.
- The i9-9900K has a higher turbo clock boost. Turbo Boost is a CPU feature that will run CPU clock speed faster than its base clock, if certain conditions are present. It will enable older software that runs on fewer cores, to perform better on newer hardware.
Since games are software too, it is also applicable to them. - The i9-9900K 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.

Estimated results for PassMark CPU Mark
Some of the CPUs listed below have been benchmarked by CPU-Benchmark. However the majority of CPUs have not been tested and the results have been estimated by a CPU-Benchmark’s secret proprietary formula. As such they do not accurately reflect the actual Passmark CPU mark values and are not endorsed by PassMark Software Pty Ltd.
Monero Hashrate kH/s
The crypto currency Monero has been using the RandomX algorithm since November 2019. This PoW (proof of work) algorithm can only efficiently be calculated using a processor (CPU) or a graphics card (GPU). The CryptoNight algorithm was used for Monero until November 2019, but it could be calculated using ASICs. RandomX benefits from a high number of CPU cores, cache and a fast connection of the memory via as many memory channels as possible

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.

Estimated results for PassMark CPU Mark
Some of the processors listed below have been tested with CPU-Comparison. However, most of the processors were not tested and the results were evaluated by the secret patented CPU-Comparison formula.

Monero Hashrate kH/s
Monero has been using the RandomX algorithm since November 2019of the year. This PoW (proof of work) algorithm can only be computed efficiently using either a processor (CPU) or a graphics card (GPU). The CryptoNight algorithm was used for Monero until November 2019, but it could be calculated using ASICs. RandomX benefits from a large number of CPU cores, cache, and fast memory connectivity through as many memory channels as possible.

i9-9900K
- The i9-9900K has a higher L3 cache. This is useful when you have significant multi-processor workloads, many computational processes at the same time. Rather on a server rather than a personal computer for interactive workloads.
- The i9-9900K has more cores. The advantage of having more cores is that the system can handle more threads. Each core can process a separate data stream. This architecture greatly improves the performance of a system running parallel applications.
- The i9-9900K has more themes. Large programs are divided into threads (small sections) so that the processor can execute them simultaneously to speed up execution.
- In some games, a processor with a higher clock speed, or with the technical name IPC (Instructions per clock), performs better than other processors with more cores and a lower core frequency.
- i9-9900K The i9-9900K is more energy efficient and generates less heat.
- The i9-9900K has a higher turbo clock. Turbo Boost is a processor feature that will run at a processor clock speed faster than its base clock speed if certain conditions are present. This will allow older software that runs on fewer cores to run better on newer hardware. Since games are also software, they are also applicable.
- i9-9900K The i9-9900K has a smaller process size. The faster a transistor can turn on and off, the faster it can work. And transistors that turn on and off with less power are more efficient, reducing the operating power or «dynamic power» required by the processor.
