About i5-13600k Architecture
This gallery summarizes the key features of the new series.
We are seeing a +200MHz boost for Core i5-13600K and a +400MHz boost for Core i7 13700k CPUs. Intel has introduced new performance cores dubbed “Raptor Cove” cores.
Intel boosted E-Core size on Raptor Lake CPUs, with the Core i5-13600K having 8 E-Cores compared to the Core i5-12600K’s 4. Core i9-13900K E-Cores hit 4.3GHz, while Core i5-13600K E-Cores top out at 3.9GHz, with doubled L2 cache shared within each cluster.
Raptor Lake CPUs now handle DDR5 speeds up to 5600MHz, and the compute fabric is also made faster by up to 900MHz. The L3 Cache size is now 24MB on the Core i5 CPU. Moreover, the new Dynamic INI (inclusive/non-inclusive) architecture in the Raptor Lake allows the sub-components to reserve portions of the L3 cache.
Intel has also worked on the software side to bring out balanced and enhanced performance from all perspectives.

Methodology
The following was ensured for each test:
- Each test is done on the Auto and Stock settings.
- Default tweaking/performance enhancement options are disabled in the BIOS.
- XMP is loaded for each test. DRAM timings and Voltage are set manually.
- All other voltages are left at Auto.
- The pump and fans of the cooling solution are set to run at 100% during the testing.
- Games are benched on the stock clocks.
- The overclocking results of the processor under discussion are shown.
- The Graphics card is not overclocked.
- The motherboards’ BIOS is updated to their latest.
- Nvidia’s driver 517.48 is used.
- HWinfo64 is used to monitor the sensors.
- Each game was tested on maxed setting using the built-in benchmark utility where available, and the MSI After Burner was used to record the FPS from the actual gameplay.
Let’s start with the results. The testing was done on Microsoft Windows 11 x64 version 22H2.
General Tests
Let’s start with some general tests.
Rendering Tests
We have run multiple rendering tests for evaluation. The results of these tests are mostly the rendering time and frames per second unless stated otherwise. Lower time and higher FPS are what we are looking for.
Transcoding
We have used X264 HD and X265 HD Benchmarks to measure the transcoding performance of the CPU.
Web-based Benchmarks
Just to give an idea of how the CPUs impact general web browsing, we ran a few benchmarks.
Gaming Benchmarks
Let’s start with the synthetic benchmarks. For this purpose, We have used 3DMark Fire Strike and Time Spy benchmarks.
Frequency
The Intel i5-13600K features a base clock of 3.50GHz for P-Cores and 2.60GHz for E-Cores. Its turbo frequency reaches 5.1GHz for P-Cores and 3.9GHz for E-Cores, with variability based on load and other factors. For example, the thermal headroom, power limit, cooling solution, thermal paste application, how good a motherboard is, etc.
![Frequency of Core i5-13600K](https://tech4gamers.com/wp-content/uploads/2022/12/i5-13600k-Sustained-Clocks.jpg)
Our unit was boosting to 5.1GHz (P-Cores) and (3.9GHz E-Cores) out of the box. This is not it. The CPU actually maintained these clocks under multi-core and single-core loads using Blender, and Cinebench R23 runs.
Thermals And Power
We have tested the Intel i5-13600K on the GIGABYTE Z790 AORUS ELITE AX motherboard with the latest BIOS update. This is not a high-end motherboard, but it still packs enough juice for the i5 and i7 CPUs. From the cooling perspective, we have set up a custom loop on the test bench when the CPU arrives for testing. The setup consists of:
- AlphaCool Eisblock XPX AURORA PRO Digital RGB – Full Brass
- AlphaCool Eisbecher AURORA with Apex VPP Pump
- AlphaCool NexXxos XT45 Full Copper SuperNova 1260mm Radiator
- AlphaCool Black Tube 16/10mm
- AlphaCool Straight Compression Fittings 16/10
- AlphaCool 45/90° Rotary Adapters
- AlphaCool Quick-Disconnect Fittings
- AlphaCool Clear Coolant
- 9x be quiet! Silent Wings 4 140mm PWM High-Speed Fans
The thermal paste used is AlphaCool SubZero, with a thermal conductivity rating of 16W-mK. In that, we have covered three aspects:
- Adequate Motherboard
- Powerful Cooling
- A high-grade thermal paste
We left the system idle for like 30 minutes and used HWInfo64 to monitor the thermals and power usage.
![HWInfo64 Thermal Screenshot of Core i5-13600K on Idle](https://tech4gamers.com/wp-content/uploads/2022/12/i5-13600k-Idle-Stats.jpg)
As can be seen in the above picture, the minimum package temperature was 30°C at an ambient of 21.5°C, and the package power was 3.397W. The minimum frequency was 0.80GHz on any core during idling. The overall stats are good. Please keep in mind that this is a hybrid architecture. If you take the Core Temperature sensor into consideration, then the idling is at 23°C.
Next, we run a Cinebench R23 30-minute run on the CPU and monitor the stats using the HWInfo64.
![HWInfo64 Thermal Screenshot of Core i5-13600K under load](https://tech4gamers.com/wp-content/uploads/2022/12/i5-13600k-Load-Stats.jpg)
The temperature under load was 76°C. The power draw on the CPU package was 179.449W. This is within the stated 181W for turbo frequency operation. All P-Cores were operating at 5.1GHz continuously, and all E-Cores were at 3.9GHz continuously. This is an impressive performance.
![HWInfo64 Power Usage Screenshots Under Load](https://tech4gamers.com/wp-content/uploads/2022/12/i5-13600k-Single-Core-Load-Stats.jpg)
We also monitored the power usage on the single-core load using Cinebench R23. The CPU was drawing roughly 33.886W, which is very good when compared to the Intel i7 12700k and AMD Ryzen 7 7700X. Please note that single-core load does not use E-Cores on the Intel hybrid architecture (in Windows 11).
![](https://tech4gamers.com/wp-content/uploads/2022/12/i5-13600k-1T-Power.jpg)
The above graph shows the power consumption on the single-threaded load from the Cinebench R23.
Contribution from E-Cores
We received an interesting query what is the contribution of E-Cores to the total performance? We decided to disable the E-Cores and run the Cinebench R23 to check the performance hit, if any. Here is the result:
Setting | VCore (V) | Package Power (W) | Package Temperature (°C) | Cinebench R23 Multi-Core Score | Cinebench R23 Single-Core Score |
Stock [With P-Cores and E-Cores] | 1.308 | 179.449 | 76 | 24454 | 2009 |
E-Cores Disabled | 1.236 | 138.309 | 69 | 16126 | 1993 |
We observed approximately 34% performance hit in the multi-core load and 0.8% performance hit in the single-core load. The single-core difference is highly marginal and can be ignored as such, but the 34% hit with disabled E-Cores is making a good point on how much these cores contribute.
Overclocking
We started with P-Cores at 5.2GHz and E-Cores at 4.0GHz. For each change, we have tested the Cinebench R23 to see if there is any performance hit or gain. This was then tested further using games and other loads for stability. We settled at P-Cores at 5.6GHz and E-Cores at 4.4GHz. This is a good overclock on this CPU. The Vcore was set at approximately 1.330V.
![Cinebench R23 Overclocking Scores for Core i5-13600K](https://tech4gamers.com/wp-content/uploads/2022/12/i5-13600k-Overclocking-R23-Comparison.jpg)
The above picture shows the performance gain from these overclocks in the Cinebench R23. We saw a performance gain of approximately 9.69%.
The CPU was drawing 192W package power approximately, and the temperature was 81°C. Please remember we are using a custom loop setup with a massive-size radiator. The results with the regular AIO or air cooler would be different, and you might actually go into thermal throttling with this overclock on a regular cooler. Any attempt to further increase the clocks was met with failures. Seems like we hit the silicon limit!
Should You Buy It?
We conducted multiple tests on the Core i5-13600K. The results have given us a fairly good idea about the processor’s use case.
Buy It If:
You are building a mid-high-end system: The core i5-13600K supersedes its predecessor when it comes to performance, making it a suitable processor to pair with high-end graphics cards.
You want a CPU for competitive titles: In our tests, the core i5-13600K performed well in single-core tasks while also keeping up in multi-threaded scenarios, making it perfect for competitive titles.

You want support for DDR4 and DDR5 memory: The Core i5-13600K supports both DDR4 and DDR5 memory kits.
Don’t Buy It If:
You want an efficient processor: During our tests, the i5-13600K remained efficient under single-threaded tasks; however, it proved to be slightly more power-hungry in multi-threaded scenarios, with its consumption spiking up to 180W.
My Thoughts
I tested the Core i5-13600K, Core i7-12700K, and Ryzen 7 7700X for energy efficiency. The Core i5-13600K outperformed the others with a score of 59.29, but in multi-threaded scenarios, both Intel CPUs consumed more power. The Core i5-13600K scored 136.27 in energy efficiency, the Core i7-12700K scored 115.56, and the Ryzen 7 7700X scored 143.40, surprising me as the Ryzen was more energy-efficient.
Gaming performance varied, with the Core i5-13600K excelling in some titles. Thermals were better, but using an AIO is still recommended. I managed to overclock it to 5.6GHz on P-Cores and 4.4GHz on E-Cores, with temperatures reaching 81°C in my DIY setup.
Intel’s advantage is platform compatibility; 13th gen CPUs work on the 12th gen platform with a BIOS update, saving users money. You can also use DDR4 RAM on the new 700 series platform, which supports both DDR5 and DDR4. The Core i5-13600K offers great performance at a competitive price, making it a cost-effective choice.
