When selecting a CPU for gaming, the most important characteristics are the frequency (clock speed), core/thread count, cache size, and supported memory type. Additional considerations, such as integrated graphics and overclocking needs, may also influence your selection.
In addition to discussing how good the 9300 is for gaming, this article will discuss our recommended:
When using Intel's Core i3 9300 CPU for gaming, you can expect poor game performance with either a high-performance CPU cooler or a stock CPU cooler.
Check out our Recommended LGA 1151 Coolers below.
This performance assessment is based on the following characteristics of the CPU and their relevance to the latest graphics-intense games:
- 8 MB of L3 cache is poor for performance
- 4 cores allow for mediocre performance
- 3.70 GHz base frequency
- 4.30 GHz single-core max turbo boost frequency is excellent for performance (requires a high-end cooler)
- Max stock DDR4 speed of 2400 MHz can be poor for performance
- Lack of overclocking support cannot benefit performance
- PCIe 3.0 support can be poor for performance (limits potential of fastest SSDs and GPUs)
- The 9300 has integrated graphics support, but this performance assessment assumes you will use a graphics card. Integrated graphics support is mediocre or worse with the latest graphics-intense games.
A CPU's cache is a small amount of memory, close to the CPU cores, containing recently used data.
Games performance can improve as cache size increases, as it will reduce delays when retrieving commonly used game assets from memory.
An L3 cache capacity of at least 20 MB is ideal for game performance.
The Intel Core i3-9300 has an L3 cache capacity of 8 MB.
The 9300's lackluster 8 MB of L3 cache is poor for performance with the latest graphics-intense games.
Increased core counts can improve the performance of games that use them, but most modern games don't benefit from having more than 6–8 cores. Remember that cache sizes often increase along with core counts, so if you want to increase your L3 cache, you may need to get a CPU with more cores.
Intel's Core i3-9300 CPUs have 4 cores.
The 9300's 4 cores allow for mediocre performance with the latest graphics-intense games.
Single-core performance is essential for some games, as many don't take full advantage of multiple cores.
Turbo boost frequencies are only achieved under ideal circumstances. The safest strategy for consistent gaming performance with a basic cooler is to get a higher base clock speed processor. However, with adequate cooling, you may be able to maintain speeds near the max boost frequency.
The 9300 CPU's lack of support for overclocking cannot benefit performance with the latest graphics-intense games.
The processor has a 3.70 GHz base frequency and supports a 4.30 GHz single-core max turbo frequency.
The 9300 has a 3.70 GHz base frequency, which is the speed before boosting. You can reach these base frequencies even without a high-end cooler.
With a high-end cooler, the 9300's 4.30 GHz single-core max turbo boost frequency is excellent for performance with the latest graphics-intense games. You can maintain these frequencies with a high-end cooler.
Check out my article, Choosing the Best CPU Cooler for Intel's Core i3-9300, for recommended coolers that can maintain these boost frequencies.
The 9300 CPU's support for DDR4 with a max stock speed of 2400 MHz can be poor for performance with the latest graphics-intense games.
Faster PC memory can improve game performance and frame rates, but using the fastest RAM may not have as much of an impact as upgrading your CPU and graphics card or adding more RAM.

The 9300 model name doesn't have an F suffix. Non-F CPUs contain integrated graphics, and a separate graphics card isn't required if your motherboard includes video-output connectors (e.g., HDMI).
The 9300 model name doesn't have a K suffix. Non-K CPUs can not be overclocked.
A CPU cooler's TDP (Thermal Design Power) rating indicates how much heat it can dissipate in watts. If the cooler can't keep your CPU cool enough, your CPU may throttle (slow down), and your cooler will constantly run at full speed.
Intel CPU specifications indicate this power dissipation number as "Processor Base Power."
The Core i3-9300 has a TDP of 62 watts.
A CPU cooler can still work with a lower TDP rating than the TDP of a CPU. However, the CPU will eventually throttle itself to a lower frequency to allow itself to cool.
The CPU may not achieve or maintain maximum turbo speeds without adequate cooling.

For Intel's 9th generation Core i3 9300 processor, you'll need a motherboard with an LGA 1151 socket and 300-series chipset.
Motherboards for Intel processors are made with chipsets provided by Intel. Each chipset offers a unique set of capabilities. However, motherboards must explicitly support features and capabilities for you to use them. Verify that a motherboard supports the features and capabilities you desire.
The lack of a "K" suffix in the model name 9300 means it doesn't support overclocking. Because of this, you may not need to use the top of the line Z390 or Z370 chipsets which support overclocking. Instead, you can use a motherboard with Intel's other 300-series desktop chipsets listed below.
For compatiblity with Intel's 11th generation Core processors, you can use any of the 300-series chipsets: Z390, Z370, H370, B365, B360, H310. These are roughly sorted from most to least functionality.
The Q370 chipset is also compatible, but is intended for business use cases; its availability in stand-alone motherboards is limited.

Locked Intel CPUs may come with a stock CPU cooler. These CPU models do not have a "K" in the name. While stock coolers will prevent your CPU from overheating, your CPU will throttle its performance during games and other intensive tasks. Higher TDP coolers will keep your CPU at turbo speeds for longer durations. Stock coolers are often quite loud at their maximum speed.

Before purchasing memory, review your motherboard specification to verify which speeds are supported. For example, if a DDR4 motherboard stated that it supports "DDR4 3400(O.C.) / 3333(O.C.) / 3300(O.C.) / 3200 / 3000," that would mean that it could support DDR4-3400, DDR4-3333, and DDR4-3300 with memory overclocking, and DDR4-3200 and DDR4-3000 at stock speeds. Motherboard specifications also indicate the maximum capacity per stick of RAM (DIMM) and across all slots.
