In the process, we will take a look at their basic specifications, compare their application and gaming performance. We will also take a look at their clock speeds, power consumption, and CPU temperatures. If you are looking to purchase a new CPU and confused between the Intel Core i5 13600K and Intel Core i5 13400F, then we hope that this guide could help you make a better buying decision.
A Brief Note on Intel Core i5 13400F
After successfully launching the regular 13th Gen CPUs, Intel recently launched a couple of non-overclockable CPUs. In that, the Intel Core i5 13400F is even special as the “F” in the name indicates that it doesn’t have any integrated graphics. So, without overclocking feature and no integrated graphics, the cost of this CPU should be very low, right? Yes. The launch price of the Intel Core i5 13400F is just $196. The Intel Core i5 13400F has a combination of Performance or P Cores and Efficiency or E Cores. To be specific, it has 6 P Cores with support for multithreading and 4 E Cores without multithreading. So, the Intel Core i5 13400F has a total of 10 Cores and 16 Threads. The base clock speed of the P and E Cores of 13400F are 2.5 GHz and 1.8 GHz respectively while the turbo clocks of P and E Cores are 4.6 GHz and 3.3 GHz respectively. It also uses the same LGA 1700 Socket as the other 12th gen and 13th processors. The Intel Core i5 13400F CPU supports both DDR4 and DDR5 RAM types in dual channel mode with frequencies as DDR4-3200 and DDR5-4800. Coming to the cache layout, each P core of the 13400F Processor gets 1.25 MB L2 Cache and one module of E cores gets 2 MB L2 Cache. Speaking of E Core modules, Intel grouped four E Cores into a cluster that share the L2 cache. So, in 13400F, you get 2 MB for four E Cores. This makes the total L2 Cache of 12900K at 9.5 MB. It also has 20 MB L3 Cache, which is common for all the cores. The Intel Core i5 13400F processor has 20 PCIe lanes from the CPU. Of these, 16 are PCIe Gen 5 while the remaining 4 are Gen 4. The 13th Gen Alder Lake processors are fabricated using the “Intel 7”. Even though Intel calls it “Intel 7”, it is technically a 10 nm node. The base processor power of Intel Core i5 13400F CPU is 65W while the maximum turbo power is 148W.

A Brief Note on Intel Core i5 13600K
In October 2022, Intel launched the 13th Gen processors with code name Raptor Lake. While the Core i9 13900K is an expensive, top-of-the-line processor of this generation (subsequently dethroned by Intel Core i9 13900KS), the Core i5 13600K is a relatively low-cost option with a launch price of $319. Continuing the Hybrid Architecture from the 12th Gen Alder Lake processors, the Intel Core i5 13600K consists of 6 Performance (P) Cores and 8 Efficiency (E) Cores. The performance cores support hyper threading but the efficiency cores don’t. So, the 6P + 8E Core 13600K supports 20 threads. The base clock speed of the P and E Cores of 13600K are 3.5 GHz and 2.6 GHz respectively. The turbo clocks of P and E Cores are 5.1 GHz and 3.9 GHz respectively. Intel made the 13th gen Raptor Lake processors using the same LGA 1700 Socket as the 12th Gen Alder Lake CPUs. So, if you have a decent motherboard, then the upgrade cost will be less. The Intel Core i5 13600K CPU supports both DDR4 and DDR5 RAM types in dual channel mode. While the DDR4 frequency is only DDR4-3200, DDR5 saw a huge improvement with support for DDR5-5600. Coming to the cache layout, each P core of the 13600K Processor gets 2 MB L2 Cache and one module of E cores gets 4 MB L2 Cache. If you aren’t familiar with the E Core modules, Intel grouped four E Cores into a cluster that share the L2 cache. So, in 13600K, you get 4 MB for four E Cores. This makes the total L2 Cache of 13600K at 20 MB. It also has 24 MB L3 Cache, which is common for all the cores. The Intel Core i5 13600K processor has 20 PCIe lanes from the CPU. Of these, 16 are PCIe Gen 5 while the remaining 4 are Gen 4. Similar to the Alder Lake processors, even the 13th Gen Raptor Lake processors are fabricated using the “Intel 7”. Even though Intel calls it “Intel 7”, it is technically a 10 nm node. The base processor power of Intel Core i5 13600K CPU is 125W while the maximum turbo power is 181W.

Developers working on large projects need a stable multi-threaded system with a powerful CPU. So, we tested the code compilation performance by taking the open-source Chromium project code. The performance of Intel Core i5 13600K is not that great as it could finish the compilation in just over 69 minutes. Even worse, the Intel Core i5 13400F finished the compilation in over 87 minutes.
Corona 1.3 Render Time (Lower is Better)
The last “application” benchmark is the Corona 1.3, which is a high-quality shading engine for production rendering. Let us now see the rendering time of different Intel and AMD CPUs.
Gaming Benchmarks
Let us move to some gaming performance. We tested some popular titles at a resolution of 1920 × 1080 (1080p) as anything beyond, the GPU will dominate the performance. We are running all the games in DirectX 12 with Ray Tracing and DLSS off.
Far Cry 6
Resolution: 1920 × 1080 DirectX 12 Game Setting: Ultra DirectX Raytracing: Off
The first game is Far Cry 6. Here, the Intel Core i5 13600K shows its dominance over Intel Core i5 13400F as the former got shy of 150 fps while the latter could only push 135 fps. Here are the rounded off average frames and also 1% low fps.
Cyberpunk 2077
Resolution: 1920 × 1080 DirectX 12 Game Setting: Ultra Texture: High Ray Tracing: Off DLSS: Off
Next, we have another popular title, Cyberpunk 2077. The story is the same, where the Intel Core i5 13600K can pump over 140 fps on average while the Intel Core i5 13400F struggle to push past 130 fps.
Shadow of the Tomb Raider
Resolution: 1920 × 1080 DirectX 12 Game Setting: High DLSS: Off
Last but not least, we tested the Shadow of the Tomb Raider. Unsurprisingly, the results are once again similar. The Intel Core i5 13600K could easily push over 230 fps while the Intel Core i5 13400F could only get over 190 fps. What surprised in this game is the AMD Ryzen 7 5800X3D beating all the current gen Intel and AMD flagships. Based on this result, we are very excited to get our hands on the upcoming Ryzen 7000 Series CPUs with 3D V-Cache.
Clock Speed
We ran the AIDA64 Stress Test for 10 minutes and here are the maximum frequency and average frequency of all cores.
CPU Temperature
During the same AIDA64 Stress Test, we monitored the CPU Temperatures with Corsair iCUE H150i RGB Elite Liquid CPU Cooler. Here are the CPU temps for your reference.
Power Consumption
During the Blender render, we measured the CPU Package Power Draw using the HWiNFO tool. The following table consists of the peak CPU Package Power Draw as reported by HWiNFO.
Which is Better, Intel Core i5 13400F or Intel Core i5 13600K?
The retail price of both the Intel Core i5 13600K is $319 while it is $196 for the Intel Core i5 13400F. A clear $120 difference. We can see this difference even in performance. From the above tests, it is clear that the Intel Core i5 13600K is worth spending the extra $100 odd bucks as you can easily get extra performance both in gaming as well as productivity applications. The advantage of the Intel Core i5 13400F is it draws less power and runs way coolers than the Intel Core i5 13600K. For gaming or mild multi-threaded workloads, the Intel Core i5 13600K is a much better choice than the Intel Core i5 13400F. Comment * Name * Email * Website
