AI Verdict
This 6-core, 12-thread LGA 1151 CPU with a 4.7GHz turbo is for gamers and multitaskers building on an Intel 300 series chipset.
This 6-core, 12-thread processor with a 4.7GHz turbo frequency is still a solid performer for gaming and general multitasking, especially if you're already on an LGA 1151 300-series motherboard. However, its platform is aging, and newer CPUs offer better efficiency and more cores for demanding applications.
If you need more multi-core performance or a more modern platform, look for a CPU with 8 or more cores and a newer socket type like LGA 1700.

Dimension Scores
The 4.7 GHz max turbo frequency provides strong single-core performance, which is still beneficial for many applications and games.
With 6 cores and 12 threads, it handles multitasking and applications that utilize multiple cores efficiently for its generation.
The 95W TDP is typical for a performance-oriented unlocked CPU of its generation, but newer architectures offer better performance per watt.
The LGA 1151 socket and 300 series chipset compatibility limit future CPU upgrades to older generations, as Intel has moved to newer sockets.
Best For
- Gamers seeking high frame rates in CPU-intensive titles.
- Users who frequently run multiple applications simultaneously, like streaming while gaming.
- Enthusiasts who want to push performance limits through overclocking.
- Anyone building a new system or upgrading an existing one on an Intel 300 series platform.
Not Recommended For
- Budget builders who cannot afford an additional aftermarket CPU cooler.
- Users looking for a CPU with an easy upgrade path to the latest Intel platforms.
- Anyone needing a processor for heavy workstation tasks like professional video rendering or complex simulations.
Watch Out For
- You'll need to buy a separate CPU cooler; the box doesn't come with one.
- Expect to invest in a capable aftermarket cooler, as some users reported overheating with less robust solutions.
- Compatibility is strictly limited to LGA 1151 motherboards with Intel 300 Series Chipsets, so don't expect it to work with older 100 or 200 series boards.
- Running Windows 11 might require a registry edit to bypass compatibility checks, as some 8th gen CPUs are not officially supported.

What Buyers Say
Users frequently highlight the i7-8700K's exceptional overclocking capabilities, often pushing it well beyond its stock 4.7 GHz turbo frequency for a noticeable performance bump. Many found it to be a powerhouse for gaming and handling multiple applications simultaneously. However, a recurring point is the necessity of purchasing a separate, capable CPU cooler, as the processor doesn't come with one and can run hot, especially when overclocked. Some also expressed frustration with Intel's rapid platform changes, making future upgrades on the same motherboard impossible.
“Man, this thing still rips in games, but seriously, why no cooler in the box? Had to drop another 50 bucks on a decent one just to keep it from melting when I pushed it past 5GHz. Still, worth it for the frames.”
Common Praise
- Reaches high clock speeds easily when overclocked, providing a performance boost.
- Maintains high frame rates in demanding games, even several years after release.
- Handles multiple open applications and background tasks without slowdowns.
- Integrated Intel UHD Graphics 630 is sufficient for basic display needs or troubleshooting.
Common Complaints
- Does not include a CPU cooler, forcing an additional purchase.
- Can run hot, especially under load or when overclocked, requiring a robust aftermarket cooling solution.
- Limited to Intel 300 Series motherboards, making it a dead-end platform for future CPU upgrades.
- Some users felt Intel's pricing and rapid platform changes were frustrating at the time of release.
Ownership Tips
- Overclocking is straightforward, but you'll need to spend time tweaking settings for stability and optimal performance.
- A high-quality air cooler or a 240mm AIO liquid cooler is almost mandatory to keep temperatures in check, especially with any overclocking.
- The integrated graphics are fine for basic tasks, but you'll definitely want a dedicated GPU for any serious gaming or creative work.
- Even after years, it holds its own in most games, but you'll notice it struggling more with newer, heavily multi-threaded applications compared to current-gen CPUs.
Frequently Asked Questions
Does the Intel Core i7-8700K come with a cooler?
No, the Intel Core i7-8700K does not include a stock cooler in its retail packaging, so you'll need to purchase one separately.

Buying Guide
When you're looking at a CPU like this, you need to think about more than just the core count. An 'unlocked' processor means you can manually increase its clock speed (overclock it), but that generates more heat, so you'll need a good cooler. Also, the 'socket' (LGA 1151) and 'chipset' (300 Series) are crucial; they tell you exactly which motherboards this CPU will physically fit into and work with. If your motherboard isn't compatible, this CPU is useless to you.
Cores/Threads
Think of cores as individual workers and threads as tasks each worker can handle simultaneously. More cores and threads mean the CPU can juggle more programs or complex calculations at once without slowing down, like having more hands to help with a big project.
Max Turbo Frequency
This is the fastest speed a single core can reach under ideal conditions, like a car's top speed. It's important for tasks that rely on one powerful core, like many games, where a higher turbo frequency can mean smoother performance.
TDP (Thermal Design Power)
This number tells you how much heat the CPU is expected to generate under typical workloads, measured in watts. It's like how much heat a lightbulb puts out. A higher TDP means you'll need a more powerful (and often larger/noisier) cooler to prevent overheating.
Socket (LGA 1151) & Chipset (300 Series)
The socket is the physical connection on the motherboard where the CPU sits, and the chipset is the set of components that manage communication between the CPU and other parts of your PC. They're like a specific type of plug and outlet; they have to match perfectly for the CPU to work with your motherboard.
Alternatives
If you need more raw multi-core power for professional applications, look for CPUs with 8 or more physical cores and higher thread counts. If you're building a brand-new system and want the latest features and upgrade path, search for processors on current-generation sockets with DDR5 RAM support.
