What is Intel Turbo Boost, Exactly?
Think of Intel Turbo Boost Technology as your CPU's personal trainer, pushing it to perform better when the workout gets tough. At its core, it’s a clever feature that automatically increases the processor's clock speed above its base frequency. When your PC is just idling or doing light tasks like browsing, the i5-14400 hums along at its standard speed, saving power. But fire up a demanding game or start rendering a video, and Turbo Boost kicks in, giving you the extra horsepower you need. It’s the key to balancing efficiency with on-demand power, a crucial factor for modern CPU processors.
How the i5-14400 Turbo Boost Actually Works
So, how does this process unfold? It's not just a simple on/off switch. The i5-14400 is constantly monitoring itself. It checks several factors in real-time:

Intel 12th Gen Core i5-12400 up to 4.40 GHz Unlocked 18MB Cache LGA 1700 65W Desktop Processor / Intel® UHD Graphics 730 / Compatible With 600 Series Chipset / BX8071512400

AMD Ryzen 7 9700X 8-Core 16-Threads 3.8GHz (5.5GHz Max Boost) Socket AM5 65W Desktop Processor / Zen 5 Architecture / AMD Radeon™ Graphics / Cooler Not Included / 100-100001404WOF

Intel 14th Gen Core i3-14100F Desktop Processor 4(4P+0E) Cores up to 4.70GHz LGA1700 Series Chipset 58W / Discrete Graphics Card Required / BX8071514100F

Intel Core Ultra 5 225 Processor / 10x (6P + 4E) Cores / 10x Threads / Up to 4.9GHz Turbo Boost / LGA 1851 Series Chipset 121W / AI Accelerator Technology / Integrated Graphics / BX80768225

AMD Ryzen 7 5700 8-Core 16-Threads 3.7GHz (4.6GHz Max Boost) Socket AM4 65W Desktop Processor / 20MB GameCache / 3rd Gen AMD Ryzen Desktop Processor / Discrete Graphics Card Required / 100-100000743BOX

AMD Ryzen 5 9600X 6-Core 12-Threads 3.9GHz (5.4GHz Max Boost) Socket AM5 65W Desktop Processor / Zen 5 Architecture / AMD Radeon™ Graphics / Cooler Not Included / 100-100001405WOF
- Temperature: Is the CPU cool enough to handle more speed?
- Power Usage: Is it operating within safe power limits?
- Number of Active Cores: Is the workload hitting just one core or all of them?
If the processor has thermal and power "headroom," it intelligently raises the clock speed of the active cores. For a task that only uses one or two cores, the i5-14400 Turbo Boost can push them to a higher frequency than if all cores are being stressed. This is why it’s so effective for gaming, as many games still rely heavily on the performance of a few primary cores. It’s this dynamic scaling that makes the latest Intel CPUs so versatile.
Performance Tips to Maximise Your Boost 🚀
While the i5-14400 Turbo Boost is automatic, you can create the ideal environment for it to stretch its legs and give you maximum performance. Getting this right is key to unlocking the full value of your chip.
Keep It Cool 🔧
This is the single most important factor. Turbo Boost will scale back aggressively if your CPU gets too hot. The stock cooler is adequate for basic use, but to maintain higher boost clocks for longer, a decent aftermarket air cooler or an All-in-One (AIO) liquid cooler makes a massive difference. Better cooling equals sustained performance.

Check Your BIOS Settings
Most motherboards have Intel Turbo Boost enabled by default. However, it's worth popping into your BIOS/UEFI (usually by pressing DEL on startup) to confirm it's active. While you're there, ensure any power-limiting features are set to your motherboard manufacturer's recommended specs to avoid throttling your 14400 performance.
Optimise Your Windows Power Plan
In Windows, navigate to Power Options and select the "High Performance" or "Ultimate Performance" plan. This tells the operating system to prioritise performance over power saving, ensuring your CPU is always ready to boost when called upon.
Monitor Your Boost Clocks ⚡
Want to see your i5-14400 Turbo Boost in action? Install a free tool like HWiNFO64 or CPU-Z. These utilities let you monitor your core clocks in real-time, so you can watch them ramp up during a gaming session or benchmark. It's the best way to confirm your cooling and settings are effective!
Maximising these settings ensures you get the most out of your investment, especially when building a powerful yet affordable rig with great value components like CPUs under R7000.

Intel's i5-14400 Turbo Boost temporarily raises core clock speeds above the base frequency to improve single-threaded and burst performance.
Boost peaks vary by workload, cooling, and power limits; single-core bursts hit higher clocks while sustained multi-core loads result in lower average boost.
Yes. Turbo Boost raises power draw and temps; monitor thermal limits and improve cooling to sustain higher boost clock speeds.
Yes. Use BIOS settings or Intel utilities to disable or tune Turbo Boost; adjusting power limits and fan curves balances performance and thermals.
Typically yes — higher single-core boost clocks often raise FPS in CPU-bound titles, but results depend on cooling and your GPU bottleneck.
Turbo Boost increases peak power draw during bursts; average efficiency for light tasks stays similar but expect higher consumption under sustained boost.
Run single-threaded and multi-threaded benchmarks, record boost clock speeds, temps, and power draw, and compare stock vs tuned settings for clear results.
