Companies that major in tech usually release new versions of their products regularly. This is also the case with Intel. The new versions offer better performance and capabilities than the previous ones.

Regarding processors, two types from Intel are popular among consumers, the Intel K and the KF. Both of these processors offer great performance, but there are some differences that you should know about before deciding which one to get.

This article will help you understand the difference between these two processor types so that you can make an informed decision.

What Is Intel K Series?

The Intel K series processors from Intel are the company’s flagship products. They offer the best performance and are usually used by gamers and power users. These processors have an unlocked multiplier, so you can easily overclock them.

The Intel K series also has features not present in the KF series. For example, the K series processors have Intel’s Turbo Boost Max Technology 3.0. This feature allows the processor to boost its clock speed beyond the base clock speed.

The K series processors also come with Intel’s Thermal Velocity Boost technology. This feature allows the processor to temporarily boost its clock speed when the CPU temperature is low enough.

What Is Intel KF Series?

The “KF” in Intel KF series processors stands for “locked.” As the name implies, these CPUs are locked, meaning they cannot be overclocked. They also don’t come with a built-in GPU, so if you want to use one of these processors, you’ll need to purchase a separate graphics card.

Difference Between Intel K and KF

You need to know the differences between Intel K and KF processors to decide which one is right for you.

Here are the key differences between these two processor types:

1. Price

Intel K processors are more expensive with a high processor frequency, but they offer significantly improved performance over the KF series. Intel KF processors have a higher processor frequency for demanding workloads.

The number of cores, frequency, and power consumption determine the price.

2. AMD compatibility

Intel K processors are compatible with AMD Socket AM2, AM3, and AM3+ sockets. Intel K processors will work with your existing AMD Cooling system, while Intel KF processors have to be cooled using the upcoming Cooler Master Hyper 212X or Gigabyte 965P.

This may be a problem for gamers and users who want the best performance.

3. Chipset Support

Intel K processors support the new Intel ICH8, while KF processors are only compatible with the Intel ICH10 chipset. This may pose a problem for some users who have older motherboard and CPU models. When you upgrade, make sure your motherboard and processor have compatible chipsets.

4. Power Management Features

Intel K processors offer the same power management features as other Intel processor types. In contrast, Intel KF processors offer more power management features that enable them to use less power when idle.

These newer CPUs are also faster under load due to increased core speeds and performance-per-watt improvements.

5. Single-core CPU Performance

Intel K processors offer a 25% – 100% higher single-core speed than Intel KF processors. The Intel K processor is generally more efficient in applications that don’t need extra performance.

6. Overlocking

The Intel K processor does not have an unlocked clock multiplier but offers a bus clock divider that can be manually adjusted. Intel KF processors have both an unlocked multiplier and a bus frequency multiplier. Both of these can be adjusted for overclocking performance.

7. Physical size

The Intel K processor is smaller and thinner than the Intel KF processor, but both are a fraction of the physical size of many desktop CPUs. This makes them ideal for laptops and other small form-factor devices.

The Intel KF processor is also available in a BGA package smaller than the standard Intel K processor.

8. Thermal interface material

The Intel K processor has a thermal interface with a copper heat spreader, while KF processors have thermal interfaces with solder-resistive thermal pastes. Copper heat-spreaders have better performance per watt because they cool faster, but copper conductors also generate more electromagnetic interference (EMI).

9. iGPU

Intel K processors have integrated graphics, but KF processors do not offer an on-die Intel HD Graphics IGP. This is usually better for pure CPU workloads, but a separate video card better handles more graphics-intensive tasks.

Games that don’t require a lot of graphics horsepowers, like League of Legends or Counter-Strike: Global Offensive, will run just fine on either type of processor.

10. Intel TXT

Intel TXT support is primarily limited to Intel KF processors because they were developed with TXT technology. The transistors in each chip are individually verified, so they can’t be modified once manufactured. This gives the KF processors a higher degree of security than the standard K processors.

The main advantage of Intel TXT is that it’s much more difficult for malware to attack a system. TXT uses a combination of hardware and software to create what’s known as a “trusted computing base.”

This means the processor can verify that the operating system and other software are legitimate before running them.

If any of the software is found to be malicious, the processor will refuse to run it. This makes it much harder for malware to infect a system, as it must find a way to bypass the TXT security measures.

11. Base Performance Score

Intel K processors have a Base Performance Score of 28.7 and a Max Performance Score of 83, while Intel KF processors have a Base Performance Score of 35.4 and a Max Performance Score of 100. This difference is due to the higher clock speeds and enhanced power management features of the KF processors.

For Intel KF processors, the extra performance is due to their unlocked multiplier, which allows for easier overclocking. However, Intel KF processors may not be the best choice for all users because of their increased power consumption. See the full review of the Intel Core i7-7700K for more details.

Intel K vs KF: Which is Better?

There are many things to consider when choosing a processor, including price, speed, and power consumption. But one of the most important factors is whether or not the processor supports overclocking.

Overclocking is the process of increasing the clock speed of a CPU above its stock speed. This can be done to improve performance or to compensate for the lack of speed when running certain applications.

Intel K-Series processors are unlocked, meaning they can be overclocked. Intel KF-Series processors are locked, meaning they cannot be overclocked.

So, which is better? It depends on your needs. If you want to overclock your processor, you’ll need to choose an Intel K-Series processor. If you don’t plan on overclocking, then an Intel KF-Series processor will be fine.

What Does K Mean on Intel Processor?

The “K” in Intel processor nomenclature stands for “unlocked.” An unlocked processor can be overclocked; its clock speed can be increased above the stock setting. Intel processors with a “K” designation are typically used by gamers and other power users who want to eke out every last bit of performance from their CPUs.

Not all Intel processors are unlocked, however. Only certain models in Intel’s lineup are designated as “K” processors. And even within a given product line, not all SKUs (stock-keeping units) are unlocked-typically. Only a handful of high-end models are.

What Does F Mean on Intel Processor?

The F on an Intel processor stands for “fragmentation.” Fragmentation is breaking down a file or document into smaller pieces so it can be stored more efficiently. When a file is fragmented, the processor stores the pieces in different locations on the hard drive.

This can help improve performance because the processor can access the pieces of the file more quickly.

However, fragmentation can also cause problems. If a file is too fragmented, it can take longer for the processor to access all of the pieces. This can slow down your computer. You can use a program like Windows Disk Defragmenter to help reduce fragmentation and improve performance.

Can You Overclock K Series?

Yes, you can overclock K series processors. However, it is not recommended for beginners as it can be very complicated and dangerous if not done properly. Overclocking can void your warranty and damage your hardware, so ensure you know what you’re doing before attempting it.
