CPU Comparison
Intel Core i5-4670K vs Intel Core i5-4670
A side-by-side comparison of specs, performance and value. The Intel Core i5-4670K debuted as the flagship unlocked quad-core processor of the initial Haswell architecture rollout in June 2013. Designed for the LGA 1150 socket, it targeted mainstream enthusiasts who wanted overclocking capabilities without paying the premium for Core i7.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Sufficient for basic office work, but the lack of Hyper-Threading means multi-threaded productivity workloads complete much slower than on modern CPUs.
The fastest locked Haswell i5 at launch, with 3.8 GHz turbo benefiting bursty office and development workloads.
Gaming
Adequate for older or esports titles at 1080p, but struggles significantly with modern CPU-demanding games due to having only four threads.
The 3.8 GHz turbo provides the best single-threaded performance among launch Haswell i5s, helping in older games, but four threads remain a hard limit for modern titles.
Virtualization
Four threads are a hard constraint for virtualization, and the lack of VT-d on this K-series part limits IOMMU passthrough capabilities.
vPro and VT-d features are excellent for IT management, but four threads limit practical virtualization workloads.
Efficiency
The 22nm Haswell architecture draws notably more power under load than modern alternatives, and temperatures spike easily due to the internal thermal paste.
84W TDP is the standard for the Haswell i5 lineup; the higher clocks do not come with a power penalty thanks to good binning.
Specialized Performance
AI / ML
- No dedicated AI acceleration hardware
- AVX2 supported but performance is vastly inferior to modern NPUs
- Not suitable for AI/ML training or inference workloads
- No dedicated AI acceleration hardware
- AVX2 and FMA3 available for basic vector operations
- DDR3 bandwidth constrains any AI inference workload
- Not suitable for local AI applications
Content Creation
Gaming
- Performs well in older DirectX 11 titles
- Lacks Hyper-Threading, causing stuttering in modern games
- Overclocking requires delidding to achieve safe temperatures
- Best paired with mid-range GPUs of its era, like the GTX 970
- 3.8 GHz turbo is the fastest among launch locked Haswell i5s
- Good for eSports and older AAA titles with a dedicated GPU
- Bottlenecks modern mid-range GPUs in CPU-intensive titles
- No Hyper-Threading limits 1% low frame rates
- Best paired with GTX 1060 or RX 580 class GPUs

Our Verdict on Each
The i5-4670K was a capable quad-core in its day, but its notorious thermal issues under the IHS severely limited overclocking headroom, making it a historical footnote compared to the refreshed 4690K.
Best for: Repairing an existing LGA 1150 system where a motherboard swap is impractical and delidding is not a concern.
