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 11900 is for gaming, this article will discuss our recommended:

Is the 11900 Good for Gaming?

Section Link

When using Intel's Core i9 11900 CPU for gaming, you can expect good game performance with either a high-performance CPU cooler or a stock CPU cooler.

Check out our Recommended LGA 1200 Coolers below.

This performance assessment is based on the following characteristics of the CPU and their relevance to the latest graphics-intense games:

  • 16 MB of L3 cache is mediocre for performance
  • 8 cores allow for excellent performance
  • 2.50 GHz base frequency
  • 5.20 GHz single-core max turbo boost frequency is excellent for performance (requires a high-end cooler)
  • Max stock DDR4 speed of 3200 MHz 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 11900 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.

Is the Cache Size of the 11900 Good for Gaming?

Section Link

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 i9-11900 has an L3 cache capacity of 16 MB.

The 11900's 16 MB of L3 cache is mediocre for performance with the latest graphics-intense games.

Is the Core Count of the 11900 Good for Gaming?

Section Link

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 i9-11900 CPUs have 8 cores.

The 11900's 8 cores allow for excellent performance with the latest graphics-intense games.

Is the Clock Speed of the 11900 Good for Gaming?

Section Link

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 11900 CPU's lack of support for overclocking cannot benefit performance with the latest graphics-intense games.

The processor has a 2.50 GHz base frequency and supports a 5.20 GHz single-core max turbo frequency.

The 11900 has a 2.50 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 11900's 5.20 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 i9-11900, for recommended coolers that can maintain these boost frequencies.

Is the DDR Support of the 11900 Good for Gaming?

Section Link

The 11900 CPU's support for DDR4 with a max stock speed of 3200 MHz 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.

What Does the Lack of a Suffix in the 11900 Name Mean?

Section Link

| N | "N" means it's a bespoke CPU for a company such as Apple. |

The 11900 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 11900 model name doesn't have a K suffix. Non-K CPUs can not be overclocked.

Cooling the 11900

Section Link

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 i9-11900 has a TDP of 65 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.

Motherboard Requirements for Core i9-11900 Processors

Section Link

For Intel's 11th generation Core i9 11900 processor, you'll need a motherboard with an LGA 1200 socket and a compatible 500-series or 400-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 11900 means it doesn't support overclocking. Because of this, you may not need to use the top of the line Z590 or Z490 chipsets which support overclocking. Instead, you can use a motherboard with Intel's other 500 or 400-series desktop chipsets listed below.

For compatiblity with Intel's 11th generation Core processors, you can use any of the 500-series chipsets: Z590, H570, B560, H510. These are roughly sorted from most to least functionality. The W580 and Q570 chipsets are also compatible, but are intended for workstation and business use cases; their availability in stand-alone motherboards is limited.

While the budget-friendly 400-series B460 and H410 won't work with the 11th generation Core processors, the Z490 and H470 400-series chipsets are compatible. However, these chipsets were designed for the 10th generations Core processors, and will limit the capabilities of your system. The W480 and Q470 chipsets are also compatible, but are intended for workstation and business use cases; their availability in stand-alone motherboards is limited.

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.
