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.
When using Intel's Core i5 11400H CPU for gaming, you can expect good gaming performance when the laptop has a high-performance cooling solution or mediocre gaming performance with a basic cooling solution. 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 allows for mediocre performance
- 6 cores allow for good performance
- 2.20 GHz base frequency is poor for performance
- 4.50 GHz single-core max turbo frequency is excellent for performance (with good laptop cooling)
- Max stock DDR4 speed of 3200 MT/s can be good for performance
- Lack of overclocking support cannot benefit performance
- PCIe 4.0 support can be excellent for performance (with the fastest SSDs and GPUs)
The 11400H 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 i5-11400H has an L3 cache capacity of 12 MB.
The 11400H's 12 MB of L3 cache allows for mediocre 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 11400H CPUs have 6 cores.
The 11400H's 6 cores allow for good 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 11400H CPU's lack of support for overclocking cannot benefit performance with the latest graphics-intense games.
The processor has a 2.20 GHz base frequency and supports a 4.50 GHz single-core max turbo frequency.
The 11400H's 2.20 GHz base frequency is poor for performance with the latest graphics-intense games. You can reach these base frequencies even without good laptop cooling.
With good laptop cooling, the 11400H's 4.50 GHz single-core max turbo frequency is excellent for performance with the latest graphics-intense games. You can maintain these frequencies with good laptop cooling.
The 11400H CPU's support for DDR4 with a max stock speed of 3200 MT/s can be good 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.
|Processor Name Suffix||Meaning|
|H||"H" means it's an enthusiast, high-performance CPU, optimized for mobile usage. Unlike high-performance desktop CPUs, these mobile CPUs use a lower base frequency to generate less heat and use less power when less processing is needed. H-series CPUs have better performance than both P and U-series CPUs, but use more power.|
The 11400H model name doesn't have a K or X suffix, which means that it can not be overclocked.
