AI Verdict
This 6-core, 6-thread LGA 1151 CPU with a 4.6 GHz turbo is for users building a budget gaming PC with a 300-series motherboard and a dedicated cooler.
This CPU is a situational fit because its 6 cores and 6 threads, combined with a 4.6 GHz turbo clock, offer adequate gaming performance for its price band if you already have a compatible 300-series motherboard. However, the lack of Hyper-Threading significantly limits its utility for modern multi-threaded applications and future-proofing.
If you need better multi-threaded performance and longevity, look for CPUs with 6 cores and 12 threads or more, or higher core counts, especially if you're not locked into an LGA 1151 platform.

Pros
- Achieves 4.6 GHz Turbo frequency, providing strong single-core performance for gaming.
- Unlocked multiplier allows for overclocking, with many users reaching 5.0 GHz.
- Integrated Intel UHD Graphics 630 provides basic display output and can run older games at reduced settings.
- Compatible with Intel Optane Memory for faster storage access.
Cons
- Lacks Hyper-Threading, limiting it to 6 threads, which can hinder performance in multi-threaded applications and newer games.
- Requires a compatible Intel 300 Series Chipset motherboard, limiting upgrade paths.
- Does not include a stock cooler, necessitating an additional purchase.
- Can consume over 150W when overclocked, requiring a robust cooling solution.
- Its 6-core/6-thread configuration struggles with multitasking compared to CPUs with more threads.
Dimension Scores
The 4.6 GHz Turbo frequency and overclocking potential to 5.0 GHz provide strong single-core performance, which is beneficial for many games.
With only 6 cores and 6 threads due to the lack of Hyper-Threading, this CPU falls below average for multi-threaded workloads compared to contemporary and newer processors.
The 95W TDP is average, but power consumption can increase significantly to over 150W when overclocked, impacting efficiency.
The LGA 1151 socket and 300-series chipset compatibility limit future upgrade options, and the lack of Hyper-Threading makes it less suitable for upcoming software demands.
Best For
- Budget-focused gaming builds on an existing 300-series motherboard.
- Gaming older titles that rely heavily on single-core performance.
- Users who plan to overclock and already own a capable cooler.
- Basic desktop use and light productivity tasks.
Not Recommended For
- Heavy multi-threaded workloads like video editing or 3D rendering.
- Users seeking long-term future-proofing for demanding applications.
- New PC builds without an existing 300-series motherboard.
- Users who prefer a CPU with an included cooling solution.
Watch Out For
- The absence of Hyper-Threading means it will struggle in games and applications optimized for more than 6 threads, leading to lower 1% lows in some titles.
- While rated at 95W TDP, actual power draw can exceed 150W when overclocked, requiring a more powerful cooler than expected.
- Compatibility is restricted to Intel 300 Series Chipsets, meaning it won't work with newer or older motherboard generations.
- Overclocking potential, while present, can lead to diminishing returns beyond a certain point, not always yielding proportional performance gains.

What Buyers Say
Many users found this CPU to be a capable gaming processor, especially when overclocked, often reaching 5.0 GHz for a noticeable boost in frame rates. However, the recurring complaint centers on its 6-core/6-thread configuration, which users felt limited its performance in multi-threaded tasks and raised concerns about its long-term viability for newer games and applications. The necessity of a separate CPU cooler was also a common point, adding to the overall cost. Some users noted that by 2020-2022, its value proposition had diminished significantly compared to newer, more thread-rich alternatives from both Intel and AMD.
“Man, this thing was fast for gaming when I got it, but now with all these new games needing more threads, it's starting to chug. Wish I'd waited for something with Hyper-Threading, and seriously, no cooler? Come on, Intel.”
Common Praise
- Achieves stable overclocks to 5.0 GHz, boosting gaming performance.
- Handles a wide range of games smoothly, particularly older titles.
- Easy to install for both novice and experienced builders.
- Integrated UHD Graphics 630 is sufficient for basic display needs.
Common Complaints
- Lack of Hyper-Threading (6 cores, 6 threads) causes performance bottlenecks in modern multi-threaded games and applications.
- Requires a separate, often expensive, CPU cooler as none is included.
- Compatibility limited to older Intel 300 Series motherboards, restricting upgrade options.
- Higher power consumption and heat generation when overclocked, demanding a robust cooling solution.
- Value proposition decreased significantly by 2020-2022 compared to newer CPUs with better thread counts.
Ownership Tips
- Overclocking to 5.0 GHz is achievable for many, but requires a high-end air cooler or AIO liquid cooler to manage temperatures effectively.
- Performance in games can vary wildly; older, less thread-intensive games run fine, but newer AAA titles might show stuttering or lower minimum frame rates.
- The integrated graphics are only for basic display; don't expect to game on them beyond very old or undemanding titles.
- Upgrading to a newer CPU will almost certainly require a new motherboard, as the LGA 1151 socket is no longer current.

Buying Guide
When you're looking at a CPU like this, you need to understand that its age and design choices, specifically the 6 cores and 6 threads without Hyper-Threading, mean it's not going to keep up with the latest and greatest. You're buying into an older platform, so make sure your existing motherboard is compatible. Also, factor in the cost of a good cooler, because you'll definitely need one if you want to push its limits.
Cores/Threads (6 Cores / 6 Threads)
Think of cores as individual workers and threads as tasks each worker can handle simultaneously. This CPU has 6 workers, each handling one task at a time. Modern software, especially games and productivity apps, increasingly benefits from more workers or workers that can multitask (Hyper-Threading), so 6 threads can be a bottleneck.
Base Clock / Turbo Clock (3.7 GHz / 4.6 GHz)
The base clock is its standard operating speed, like a car's cruising speed. The turbo clock is its maximum speed when it needs to work harder, like hitting the gas for a quick burst. Higher turbo speeds are crucial for gaming, as many games still rely heavily on single-core performance.
Unlocked (K-series)
An 'unlocked' CPU means you can manually increase its clock speed beyond the factory settings, a process called overclocking. This can squeeze out more performance, but it requires a compatible motherboard (Z-series) and a more powerful cooling solution to prevent overheating.
LGA 1151 Socket / 300 Series Chipset
This refers to the physical connection type on the motherboard. This CPU only fits motherboards with an LGA 1151 socket that use an Intel 300 Series Chipset. It's like a specific plug for a specific outlet; you can't mix and match with newer or older generations.
Alternatives
If this CPU doesn't fit your needs, look for processors with 8 or more threads for better multitasking and future-proofing, or consider newer generations with more efficient architectures and integrated Hyper-Threading.
