Based on our evaluation of using Intel's Core i9-14900KF CPU for general apps, you can expect excellent app performance with a high-performance CPU cooler.
If you're only planning to stream shows, use office apps, or browse the internet, you won't need a top-end CPU to get good performance. The most important CPU capability for general app usage is the single-core max turbo boost frequency.
Browsers depend on your CPU to quickly load pages and video content and manage multiple browser tabs. Higher single-core turbo boost frequencies can speed up page load times.
Office and web applications are typically single-threaded, so running a single application won't take advantage of a many-core CPU.
The more cores a CPU has, the more applications you can run simultaneously without noticing a performance impact.
Office and web applications rarely max out the CPU for long periods. These applications can use turbo boost speeds when a burst of processing power is needed, returning to the more efficient base frequencies afterward.
We took all of these factors into account while assessing the expected CPU performance for general apps.

However, more CPU cores can improve performance when running demanding web apps in multiple windows.
Intel's 12th generation and newer CPUs have performance cores (P-cores) and efficiency cores (E-cores). The P-cores are comparable to previous generation 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. E-cores do not support hyper-threading.

Higher vs. Lower Base Frequencies
We've found that lower base clock speeds result in lower power consumption.
A CPU's base frequency refers to the clock speed at which its cores run under normal operating conditions. However, the actual clock speed of the CPU can vary depending on the workload and the system power state.
A lower base frequency can lead to better power savings overall since the clock speed decreases when the load is low, resulting in lower power consumption. However, a CPU may run slower than the base frequency to conserve power or reduce heat generation. For example, modern CPUs use technologies like Intel SpeedStep or AMD Cool'n'Quiet to dynamically adjust the CPU's clock speed based on the system's workload and power state.
A CPU with a lower base frequency may generate less heat under normal operating conditions, enabling it to boost some cores to higher frequencies while remaining within its thermal limits. This lower base frequency results in better performance than a CPU with a higher base frequency, which may not be able to sustain its boost frequency for long periods due to thermal throttling. However, this is mostly only relevant if your system's cooling solution can only partially dissipate the heat produced by all cores being fully boosted.
DDR Support
The 14900K CPU's fastest supported DDR memory type is DDR5, with a max stock speed of 5600 MHz.
The 14900KF CPU's fastest supported DDR memory type is DDR5, with a max stock speed of 5600 MHz.
You can exceed these stock speeds officially supported by CPUs when overclocking memory, such as with an XMP profile. Motherboard specifications will indicate their supported overclocked-memory speeds. To be able to overclock DDR memory, your motherboard chipset needs to support memory overclocking.
Faster PC memory can improve game and professional tool performance by reducing the time it takes to perform calculations and data operations.
We've experienced that using the quickest RAM may not have as much of an impact as upgrading your CPU and graphics card or adding more RAM.

Cache Size
The Intel Core i9-14900K has an L3 cache capacity of 36 MB.
The Intel Core i9-14900KF has an L3 cache capacity of 36 MB.
A CPU's cache is a small amount of memory, close to the CPU cores, containing recently used data. An L3 cache capacity of at least 20 MB is ideal for games and professional tool performance.
Games and professional tool performance can improve as cache size increases, as it can reduce delays when retrieving commonly used assets from memory. While nearly any task will use a CPU's cache, our research indicates that a large cache becomes less impactful for general PC usage, such as browsing webpages.
Remember that cache sizes often increase with core counts, so if you want to increase your L3 cache, you may need to get a CPU with more cores.
Overclocking
The 14900K supports overclocking.
The 14900KF supports overclocking.
Overclocking is mainly relevant for PC gamers who want to maximize their game framerates. CPU overclocking increases frequencies past their default limits. Excellent heat dissipation via fans or another solution is required to maintain system stability while overclocking. While we felt a sense of excitement and anticipation when we pushed the limits of our CPU's performance, it's essential to remember that overclocking comes with the risk of damaging your system components or voiding warranties.
Professional tools can benefit from overclocked frequencies. However, overclocking may introduce some possibility of system instability, which may be less acceptable in business scenarios. We've found out the hard way that losing work due to system instability is a pain.
