CPU Comparison
Intel Core i5-4690K vs Intel Core i5-6600K
A side-by-side comparison of specs, performance and value. The Intel Core i5-4690K is the quintessential Devil's Canyon processor, released in June 2014 as a direct response to the thermal complaints surrounding the original Haswell architecture. Alongside the i7-4790K, it featured an upgraded Next-Generation Polymer Thermal Interface Material (NGPTIM) between the CPU die and the integrated heat spreader, dramatically improving heat transfer and overclocking headroom.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Sufficient for light office work and basic multitasking, but the absence of Hyper-Threading means multi-threaded productivity workloads complete noticeably slower than on contemporary i7 or modern processors.
Lacks hyper-threading, making it slow for modern multi-threaded productivity workloads.
Gaming
Adequate for older and esports titles at 1080p, but struggles with modern CPU-demanding games that utilize more than four threads, leading to stuttering and frame drops.
Bottlenecks modern GPUs in CPU-heavy titles due to 4 threads, but adequate for older or eSports games.
Virtualization
Four threads are a hard constraint for running multiple virtual machines simultaneously; VT-x is supported but VT-d is not available on this K-series part, limiting IOMMU passthrough options.
Very limited for VMs due to low thread count and lack of ECC support.
Efficiency
The 22nm Haswell architecture draws notably more power under load than modern alternatives, and the 88W TDP can exceed 120W when overclocked.
14nm Skylake was efficient for its time, but 91W TDP is high by today's standards for 4 cores.
Specialized Performance
AI / ML
- No dedicated AI acceleration hardware
- AVX2 supported but performance is far below modern NPUs
- Not suitable for any meaningful AI/ML training or inference workloads
- No AI acceleration hardware
- 4 threads severely limit local inference capabilities
Content Creation
Gaming
- Performs well in older DirectX 11 titles and esports games like CS:GO
- Lacks Hyper-Threading, causing frame-time inconsistencies in modern titles
- Overclocking to 4.4-4.6 GHz can improve minimum frame rates in CPU-bound scenarios
- Paired with a mid-range GPU like GTX 1060 or RX 580, it remains a balanced pairing for 1080p
- Struggles in modern AAA games that use 6+ threads
- Great for eSports titles like CS:GO and Valorant
- Overclocking helps maintain minimum frame rates

Our Verdict on Each
The i5-4690K was the go-to unlocked quad-core for gamers on a budget during the Haswell era. Its Devil's Canyon thermal improvements made it a better overclocker than the i5-4670K, but the lack of Hyper-Threading limits its relevance for modern multi-threaded workloads.
Best for: Repairing or upgrading an existing LGA 1150 system where a motherboard swap is impractical, and overclocking is desired.
Read the full reviewA legendary overclocker in its day, the i5-6600K brought DDR4 and PCIe 3.0 to the mainstream, though its 4-thread limitation shows its age in modern titles.
Best for: The Intel Core i5-6600K is only recommended today if you already own an LGA 1151 motherboard and DDR4 memory, and you are looking for a drop-in upgrade or replacement for a broken Pentium or i3 on a strict zero-budget. It can still handle everyday web browsing, office tasks, and esports titles like CS:GO or Valorant reasonably well. If you are building a system from scratch, there is absolutely no reason to purchase this processor new. Modern entry-level CPUs like the i3-12100F or Ryzen 5 5600 dramatically outperform it in every metric while offering a viable upgrade path. The used market is the only place this chip makes sense, and even then, you should avoid paying more than a fraction of its original launch price due to its heavily constrained multi-threading capability and dead-end platform status.
