To say that the processor is the heart of every computer is to state the obvious. The choice of the right CPU has a huge impact on the overall functioning of the computer, and everything truly depends on it. The other components complement it, and their performance is dependent on the processor’s parameters. When faced with the need to purchase the heart of our computer, we want to make the best possible choice, which, as it turns out, is not that simple. We have to answer a series of important questions, compare prices, parameters, and ultimately choose the one that offers the best balance of quality and price within our budget. Processors from Intel enjoy great popularity, as the company offers a wide range of these components. The Intel Core i5 family represents the most optimal solution for those seeking excellent parameters at a reasonable price. Below, we present a ranking of Intel Core i5 processors, in which we will attempt to answer the question of which is the best i5 processor.
TOP 5 best i5 processors
5. Intel Core i5-7600K i5 processor
We begin the comparison of Intel Core i5 processors with the model Intel Core i5-7600K. It belongs to the Kaby Lake family, which is slightly older, the 7th generation of Intel processors. However, it is included in our ranking for a reason. Equipped with 4 cores and 6 MB of cache, it offers a decent level of performance. The base clock speed is 3.8 GHz, but with Turbo Boost, it can reach a strong 4.2 GHz. The unlocked multiplier provides ample overclocking potential, further increasing its capabilities. It is well-suited for gaming, graphic design applications, and video editing, of course, with proper support from other components. This processor has also been included in our ranking with consideration for users of older computers who won’t have to invest in a new, more expensive motherboard dedicated to the processors of subsequent generations.
4. Intel Core i5-8400 i5 processor
Next, occupying the 4th place in our ranking, we have the Intel Core i5-8400 processor. It is the first representative of the 8th generation processors, known as Coffee Lake, in our lineup. It is equipped with six cores with a base clock speed of 2.8 GHz. While it doesn’t have an unlocked multiplier, which prevents overclocking, it can reach up to 4 GHz with Turbo Boost. Performance tests show that the Core i5-8400 falls only slightly behind the more expensive Core i7-8700K, positioning itself quite well, particularly in gaming. When paired with a good graphics card, it allows for comfortable gaming at high settings in the latest titles. It has 9 MB of cache memory and supports dual-channel DDR4 2666 MHz memory modules, making it a good choice not only for gamers but also for those involved in photo editing or video editing. An additional advantage of this processor is its low power consumption.
3. Intel Core i5-9400F i5 processor
The next processor in the lineup is the Intel Core i5-9400F, which is a newer version of the Intel Core i5-8400. This processor is equipped with 6 cores with a clock speed of 2.9 GHz (so the 100 MHz increase in clock speed compared to its predecessor is rather symbolic), with the ability to boost the clock speed up to 4.1 GHz using Turbo Boost. Like the i5-8400, it has a locked multiplier, which means overclocking is not possible, but the performance of both units is at a similar level. This makes it a good choice for gamers as well, although basic usage requires a separate GPU since this model does not have an integrated graphics card. However, this fact should not be seen as a disadvantage because adding a graphics card is a common practice, and the lower price compared to the Intel Core i5-8400 with very similar performance works strongly in its favor.
2. Intel Core i5-8600K i5 processor
The number 2 processor in our lineup is the Intel Core i5-8600K. It is the first 8th generation processor with an unlocked multiplier, putting it on par with the i5-7600K. The i5-8600K operates at a base clock speed of 3.6 GHz, and with Turbo Boost, it can reach up to 4.3 GHz. It features six physical cores and six threads, just like the previous Coffee Lake processors we discussed. However, while the performance results were good for the earlier two processors, they are fantastic for the i5-8600K. Combining high performance per thread with an optimal number of physical cores, this processor excels not only in demanding games but also in video editing tasks at 4K resolution. The performance-to-price ratio is even better than that of its predecessors in the ranking, and this processor can easily compete with many i7 family processors.
1. Intel Core i5-9600K i5 processor
The best i5 processor and the leader of our lineup is the Intel Core i5-9600K. It is part of the latest 9th generation of Intel processors and is equipped, like the discussed 8th generation units, with 6 physical cores and 6 threads. The base clock speed of the i5-9600K is 3.7 GHz, and with Turbo Boost, it can increase up to 4.6 GHz. Thanks to its unlocked multiplier, it can even reach nearly 5 GHz, which is truly impressive. With its soldered heat spreader, the i5-9600K allows for safe overclocking without overheating. Even the most demanding users won’t have any complaints about this processor, as it performs exceptionally well. It excels in tasks such as video rendering, and users can avoid paying extra for significantly more expensive i7 processors. The combination of price, quality, and performance makes the Intel Core i5-9600K the best i5 processor on the market.
