Intel Core i9-13900K vs Intel Core i9-13900KF

Intel Core i9-13900K vs Intel Core i9-13900KF

If you’re looking for the right processor to power your PC setup, it’s hard to go wrong with either Intel’s Core i9-13900K or 13900KF.

Both offer great performance that can give a huge boost to almost any gaming rig – plus there are some key differences between them too!

So take a look at both and figure out which one is best suited for your needs.

Let’s compare the specs and features of both models so you can decide which is best for you.

Specs comparison

Both the Intel Core i9-13900KF and Core i9-13900K are powerhouses of modern technology. With 24 cores and 32 threads, you can take advantage of lightning-fast processing speeds up to 5.80 GHz!

Plus, with its dual memory channels supporting 128GB RAM max – it’s ready for serious computing tasks or high-volume gaming. 

When it comes to performance and power consumption, both the i9-13900K and KF are well-matched. But if you’re looking for a little more bang out of your processor – like playing some low-intensity games or watching movies on the integrated GPU — then the 13900K is worth considering due to its inclusion of an integral graphics processor – Intel UHD Graphics 770 within that 125-watt TDP package.

Cinebench R23 (Single-Core)

The Intel Core i9-13900KF and 13900K processors are powerhouses, both delivering an impressive single-core Cinebench R23 score of about 2240

Cinebench R23 (Multi-Core)

Both processors offer an incredible Cinebench R23 (Multi-Core) score of 15350, allowing you to take on any task quickly and efficiently.

Cinebench R20 Single Core & Multi-Core Benchmarks

Cinebench R20 is a popular benchmarking software used to measure the performance of CPUs in both single-core and multi-core operations.

The single-core test evaluates the performance of your CPU when only one core is active, while the multi-core test measures the performance of your CPU when multiple cores are active.

The main difference between these tests is the number of active cores during the benchmarking process.

In general, multi-core performance tends to be more important for professional users who work with applications that require a lot of processing power, such as video editing, rendering, or scientific calculations!

For gaming and regular home use, single-core performance is often more than sufficient – as per our tests! – as games and most applications only use one or two cores, right? 🙂

Cinebench R20 Single Core & Multi-Core Tests: 870 and 15000, respectively

Geekbench 6 (Single-Core) and Multi-Core Benchmarks

We love the Geekbench 6’s latest version – it is optimized and updated to provide meaningful insights into the speed and ability of a device’s processor!

Now, Geekbench 6 is so good as it measures the processing power of your device’s CPU by performing complex calculations and scoring it based on your device’s hardware configuration.

The single-core test is designed to evaluate how well your device can operate with highly demanding tasks. It utilizes a single thread and tests one core of your device’s processor, enabling it to perform highly complex mathematical computations in one go.

On the other hand, Multi-Core testing is useful in measuring the device’s multi-tasking capabilities. It assesses how well the device can allocate processing power to multiple threads and cores at the same time. 

Depending on your device’s intended purpose, you may be interested in putting more emphasis on one test over the other. If, for instance, you plan on using your device to handle highly demanding applications, then the Single-core test should be the benchmark testing area that should grab your attention.

Multi-Core testing, on the other hand, is designed to evaluate the device’s ability to multi-task. It is essential to ensure that your device can handle multiple applications and software running in the background without any significant issues, especially for those who deal with multitasking regularly.

Remember, if you plan on purchasing an office or drafting a new work computer, you may want to put more emphasis on Multi-core tests – we look at these scores more vigorously!

The Multi-core test allows the device to run huge applications simultaneously without heat or lags, keeping your work seamless and efficient.

Geekbench 6 Single Core & Multi-Core Tests: 2800 and 20300, respectively!

PassMark CPU Mark Benchmark

Another popular hit here with our testing team is the PassMark CPU Mark is a benchmarking tool that measures the performance of a processor by running a series of tests on it!

It is developed by PassMark Software, a leading provider of software for benchmarking and performance testing.

We love the way that this tool gives a score to each processor, indicating its relative performance compared to other CPUs in the market.

PassMark CPU Mark tests the processor’s performance by running a suite of tests that push the CPU to its limits! – yes, it’s limits!

These tests include arithmetic operations, compression, image processing, and encryption. The tool generates a score for each processor that reflects its performance in these tests.

The score is an average of the performance across all tests, and the higher the score, the better the performance!

PassMark CPU Mark Tests: 59000

Cinebench R15 (Single-Core) and Multi-Core Benchmark Tests

Cinebench R15 is a powerful software that puts CPUs to the test and provides an overall score based on its rendering and speed capabilities.

It is a benchmarking tool created and distributed by Maxon, a German company that specializes in creating 3D modeling, rendering, and animation software products. Cinebench is a short form for Cinema 4D, which is Maxon’s 3D rendering engine. The company created this benchmarking tool to evaluate a computer’s CPU’s performance in highly visual applications.

Cinebench R15’s single-core test is a CPU benchmarking test that puts a single CPU core to test. The stress test is conducted by throwing complex rendering and 3D modeling tasks on one core – this will cancel out the effect the other cores might have on the CPU’s performance.

The single-core test is important because it gives us an insight into the CPU’s performance under heavy, individual loads – this means it will test how fast a single processor can handle high pressure.

The second type of test conducted by Cinebench R15 is the multi-core test. As the name suggests, the multi-core test is a benchmarking test that uses all available CPU cores – this means it evaluates the performance of all the cores working in unison.

This test helps measure the CPU’s ability to handle multiple tasks simultaneously, indicating how well the processor performs under heavy loads of all cores, which is quite a common scenario in 3D modeling and graphics rendering.

Cinebench R15 Single Core & Multi-Core Tests: 300 and 6000, respectively

Price

The i9-13900K and KF are pretty much neck and neck in performance, but the KF has a sweet price tag of $50 less than its counterpart. The retail suggestion might vary depending on where you get it – could be cheaper or more expensive!

Conclusion

If you’re in the market for a powerful processor that’ll give an awesome gaming and editing experience, then it’s worth considering both Intel Core i9-13900K and 13900KF.

The former has its own graphics card which means enhanced visuals but will cost more than the latter.

On the other hand, if budget is key or you’d prefer to have your dedicated GPU anyway, then go with i9-13900 KF – plus there’s always good old overclocking goodness!

Ultimately though – it depends on what tasks you want to perform so weigh up those pros & cons before deciding which of these two processors is right for you! 🙂
