When building a PC, the choice of processor will be the most important decision you make as the choice of processor influences how well your computer performs specific tasks. The type of processor you pick will have massive effects on your gaming performance, this mainly depends on the processor’s specifications and whether it has sufficient single-core performance.
Single-core performance is the most important aspect of a CPU when picking a processor for gaming, this is because most games are coded to be single-core users. This means the more cores you have won’t increase the FPS, it will only make multitasking better, this means background tasks will run more effectively when gaming.
Answer: I5 processors are great gaming processors because they’re made to be affordable and provide great single-core performance. The I5 lineup of processors has gamers in mind because they understand gamers aren’t looking for multi-core CPUs but rather CPUs with decent single-core performance. This means the overall price will be lower as these types of CPUs generally fall in the mid-tier category.
The Type Of I5 Matters
There are different types of I5 processors, not all are made the same and some will have vastly different features. I5 processors will come with varying microarchitectures, different features such as overclockability, and power consumption. In general, you will want to select the latest generation of I5s as they usually feature IPC and clock speed improvements over the previous generations.
For the best single-core performance you will want to stay away from the low TDP models as they tend to have lower single-core performance compared to the standard i5s. The most important thing when picking up a CPU for gaming is the single-core Performance so always keep that in mind. Typically, the K and non K variants of the i5s are great selections such as the i5 12600 and the i5 12600K
There are many generations of I5s as well as their counterparts (I3, I7, I9), Intel CPU generations will usually be stated in the CPUs name. For example, the I5 12600K processors are part of the Intel 12th generation processors, and the I5 11600K is part of the 11th generation. Focus on the latest generations are previously stated, but we will list all the generations and their single-core performance.

Single-Core Performance Vs Multicore Performance
Single-Core performance is the more advantageous metric when it comes to gaming performance, this is because games will see more cores as redundant. 60% of games are actually coded in such a way that they use a single-core, it’s pretty hard to code games to use multiple cores. Higher clock speeds generally mean more frame rate, but it isn’t this simple as there are more factors to consider when it comes to single-core performance.
The single-core performance is actually a combination of two metrics, this being clock speed, and IPC, you don’t hear about IPC as it isn’t a popular metric to follow, but it has a huge impact on the single-core performance. IPC stands for instructions per clock, and it refers to how many instructions a core can execute per clock cycle. So higher IPC is better as each clock cycle will complete more work, comparing a 5GHz processor with a 5GHz processor with a 10% IPC increase will show the latter processor produces more frame rates.
This is why it isn’t recommended to go for older processors even though they have higher clock speeds, processors always make IPC increases per generation. IPC increases are a product of the processor’s architecture becoming more efficient, architecture improvements are a collective result of small differences and techniques being implemented.
Just because single-core performance is the most important factor when considering a processor for gaming, it doesn’t mean you can do with just one core. You need multiple cores to handle crucial system operations such as handling the operating system. Even though you really need one core, applications running in the background will suffer if you don’t have enough cores, and this can be a huge problem if you’re into streaming.
You’ve probably noticed that I5 processors now come with hyperthreading, this technology used to be exclusive to the high-end processors such as i7s and I9s. Hyperthreading is an impressive piece of technology and it’s a form of SMT proprietary to Intel processors, it effectively splits a single physical core into two logical cores in an attempt to increase the efficiency of each core. While most applications can experience up to 30% more performance due to hyperthreading, gaming won’t benefit from this as games are single-core coded.
The best way to get more performance out of your processor is to overclock, this is quite easy as motherboards nowadays have streamlined the overclocking process. When overclocking, ensure that your I5 processor is capable, the I5s denoted with a “K” at the end means they’re unlocked and ready for overclocking. Overclocking your I5 will immediately result in higher frame rates in games as it reduces the bottleneck the CPU has on the GPU, but before overclocking, ensure you have sufficient cooling.
Is I5 Good For Gaming & Streaming?
To understand whether your I5 is good enough for streaming, we need to understand how streaming works. Streaming is a multithreaded application which means it benefits from having more processing cores, this mainly depends on the encoder. Software encoders such as the X264 encoder will work better with more cores, that’s why streaming PCs require at least 6 cores to run effectively.
Many i5 processors come with 6 physical cores and 12 logical cores which is enough for streaming, the logical cores will help due to the extra efficiency. Most streamers use the OBS software to stream, and the OBS software uses the x264 encoder. Running on the default settings in OBS should be the perfect combination for beginners as it mixes quality and CPU usage. Many users will prefer to go for a Ryzen 5 setup for streaming, this is because Ryzen processors are superior for multicore operations.
|CPU||Core Count(Threads)||Clock Speed(Boost)||Passmark Multi-Core Score||Cinebench Multi-Core Score|
|Ryzen 5 3600||6(12)||3.6GHz(4.2GHz)||17827||9383|
|Ryzen 5 3600X||6(12)||3.8GHz(4.4GHz)||18294||9458|
|Ryzen 5 5600X||6(12)||3.7GHz(4.6GHz)||22135||11735|
For streaming, we’re going to focus on the multi-core performance of the i5 processors and measure them against popular Ryzen 5 processors which are i5’s AMD counterparts. Ryzen is known for their great multi-core performance, so if I5 processors can hold up against them, then it’s a great choice when it comes to software encoding. As you can see in the benchmark compilation down below, the I5 processors can hold up against the Ryzen 5 5600x processors, keep in mind the Ryzen 5 5600x CPUs are meant to compete against Intel 10th gen chips
