CPU Comparison
Intel Core i5-4570S vs Intel Core i5-4670K
A side-by-side comparison of specs, performance and value. The Intel Core i5-4570S is a quad-core desktop processor introduced in June 2013 as part of the Haswell generation. Designed with a 65-watt TDP, the 'S' suffix indicates its focus on power efficiency without sacrificing too much performance. Operating at a base frequency of 2.9 GHz and boosting up to 3.6 GHz, it provided a balanced approach for both everyday tasks and moderate workloads. Built on Intel's 22nm process, it packs 1.4 billion transistors into a 177 mm² die. This processor was a favorite for small form factor builds and home theater PCs (HTPCs) where heat dissipation was a priority. It features Intel HD 4600 integrated graphics, capable of handling 4K video playback and older games at low settings. With 6MB of L3 cache, it delivered snappy application responsiveness. While obsolete by today's standards, it was a highly regarded efficiency chip during its prime.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Snappy for basic tasks, 6MB cache helps responsiveness.
Sufficient for basic office work, but the lack of Hyper-Threading means multi-threaded productivity workloads complete much slower than on modern CPUs.
Gaming
Handles older games well but bottlenecks modern GPUs.
Adequate for older or esports titles at 1080p, but struggles significantly with modern CPU-demanding games due to having only four threads.
Virtualization
Can run basic VMs but limited by 4 threads.
Four threads are a hard constraint for virtualization, and the lack of VT-d on this K-series part limits IOMMU passthrough capabilities.
Efficiency
Excellent power-to-performance ratio for its generation.
The 22nm Haswell architecture draws notably more power under load than modern alternatives, and temperatures spike easily due to the internal thermal paste.
Specialized Performance
AI / ML
- Lacks modern AI instruction sets
- Not suitable for AI workloads
- No dedicated AI acceleration hardware
- AVX2 supported but performance is vastly inferior to modern NPUs
- Not suitable for AI/ML training or inference workloads
Content Creation
Gaming
- Needs a dedicated GPU for 3D gaming
- Suitable for e-sports titles from the 2010s
- Will bottleneck any GPU newer than a GTX 1060
- 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

Our Verdict on Each
A great efficiency-focused CPU for its time, still viable for basic legacy systems but not for modern workloads.
Best for: Drop-in upgrade for older LGA 1150 office PCs.
Read the full reviewThe 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.
