When selecting a CPU for gaming, the most important characteristics are the clock speed (or frequency), number of cores and threads, cache size, and type of memory it supports. Additional considerations like integrated graphics and overclocking needs may also influence your selection.
This article explains the features of Intel's Core i5-1240P laptop CPU and how it performs with gaming. We compare the CPU's attributes rather than benchmarks to help you determine which features are most important when selecting a laptop.
When using Intel's Core i5-1240P CPU for gaming, you can expect good game performance when the laptop is good at dissipating heat or mediocre game performance with inadequate heat dissipation. Most laptops will fall somewhere in between in terms of their cooling capabilities. This performance is based on the following characteristics of the CPU and their relevance to the latest graphics-intense games:
- 12 MB of L3 cache is mediocre for performance
- 4 Performance cores allow for mediocre performance
- 1.70 GHz base frequency
- 4.40 GHz single-core max turbo boost frequency is excellent for performance (requires good heat dissipation)
- 4.40 GHz max turbo boost frequency of the Performance cores are excellent for performance (requires good heat dissipation)
- DDR5 support with a max stock speed of 4800 MHz can be excellent for performance
- The 1240P also supports LPDDR5, DDR4, and LPDDR4x, which may have reduced performance compared to DDR5 memory.
- Lack of overclocking support cannot benefit performance
- PCIe 5.0 support can be excellent for performance (with the fastest SSDs and GPUs)
- The 1240P has integrated graphics support, with the CPU and GPU on a single chip die, known as an APU. However, this performance assessment assumes you will use an internal or external 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 i5-1240P has an L3 cache capacity of 12 MB.
The 1240P's 12 MB of L3 cache is mediocre 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 i5-1240P CPUs have 4 Performance (P) cores and 8 Efficiency (E) cores for a total of 12 cores.
The P cores are comparable to previous generation cores. Running a game will primarily use P cores.
E cores are focused on adding additional threads in an energy-efficient manner. They take up much less room on the CPU and generate less heat. However, their smaller cache and minimal interconnect capabilities make them more appropriate for offloading background tasks.
The 1240P's 4 Performance 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.
The safest strategy for consistent gaming performance with a laptop is to get a higher base clock speed processor. High base frequencies will ensure that the laptop was designed to adequately cool the CPU at the base frequency. With exceptional cooling, you may be able to maintain speeds near the max boost frequency. However, laptops usually cannot cool CPUs enough to support constant boost frequencies. Turbo boost frequencies are only achieved and sustained under ideal circumstances.
The 1240P CPU's lack of support for overclocking cannot benefit performance with the latest graphics-intense games.
The 4 Performance cores have a 1.70 GHz base frequency and support a 4.40 GHz max turbo frequency.
The 1240P has a 1.70 GHz base frequency, which is the speed before boosting. You can reach these base frequencies even without good heat dissipation.
With good heat dissipation, the 1240P's 4.40 GHz single-core max turbo boost frequency is excellent for performance with the latest graphics-intense games. You can maintain these frequencies with good heat dissipation.
With good heat dissipation, the 1240P's 4.40 GHz max turbo boost frequency of the Performance cores are excellent for performance with the latest graphics-intense games. P core turbo boost frequencies can be maintained with good heat dissipation.
The 1240P CPU's support for DDR5 with a max stock speed of 4800 MHz can be excellent for performance with the latest graphics-intense games.
The 1240P also supports LPDDR5, DDR4, and LPDDR4x, which may have reduced performance compared to DDR5 memory.
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.

|Processor Name Suffix||Meaning|
|P||"P" means it's a mid-range performance mobile CPU. P-series CPUs fall between the H and U-series in terms of performance and power usage.|
The 1240P model name doesn't have a K or X suffix, which means that it can not be overclocked.
