CPU Comparison
Intel Core i5-4570S vs Intel Core i5-4590
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.
Adequate for basic office tasks. The 3.7 GHz turbo helps with bursty single-threaded workloads like application launches.
Gaming
Handles older games well but bottlenecks modern GPUs.
The 3.7 GHz turbo helps in older and eSports titles, but four threads remain a hard ceiling for modern gaming workloads.
Virtualization
Can run basic VMs but limited by 4 threads.
Four threads are insufficient for practical virtualization despite VT-x and VT-d support.
Efficiency
Excellent power-to-performance ratio for its generation.
84W for this performance is unimpressive by modern standards. Competing architectures now deliver 3x the performance per watt.
Specialized Performance
AI / ML
- Lacks modern AI instruction sets
- Not suitable for AI workloads
- No AI acceleration hardware
- AVX2 available but insufficient for practical inference
- DDR3 bandwidth severely constrains any AI workload
- Not recommended for any local AI tasks
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
- Best gaming CPU in the standard Haswell i5 lineup at launch
- 3.7 GHz turbo provides solid single-threaded performance for the era
- Still capable with eSports titles like CS:GO and Valorant at 1080p
- Bottlenecks anything above a GTX 1060 or RX 580 in modern titles
- DDR3 memory bandwidth limits minimum frame rates in open-world games

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 i5-4590 was arguably the best value in the Haswell i5 lineup, offering the highest clock speeds among non-K SKUs at launch. It remains functional for basic computing but is thoroughly outclassed by modern budget processors.
Best for: Dropping into an existing LGA 1150 system as a replacement or upgrade from a Pentium or i3
