CPU Comparison
Intel Core i5-4590 vs Intel Core i5-4590T
A side-by-side comparison of specs, performance and value. The Intel Core i5-4590 is a mid-cycle Haswell refresh quad-core processor with 3.3 GHz base and 3.7 GHz turbo clocks, offering improved clocks over the launch i5-4570 while maintaining the same 84W TDP and LGA 1150 platform.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Adequate for basic office tasks. The 3.7 GHz turbo helps with bursty single-threaded workloads like application launches.
Adequate for basic office tasks where bursty workloads benefit from the 3.0 GHz turbo, but sustained multi-threaded work is limited.
Gaming
The 3.7 GHz turbo helps in older and eSports titles, but four threads remain a hard ceiling for modern gaming workloads.
The 2.0 GHz base clock severely limits gaming performance. Only viable for very old or casual games, even with a dedicated GPU.
Virtualization
Four threads are insufficient for practical virtualization despite VT-x and VT-d support.
Four threads at low clocks make virtualization impractical for any meaningful workload.
Efficiency
84W for this performance is unimpressive by modern standards. Competing architectures now deliver 3x the performance per watt.
The 35W TDP was impressive for a quad-core in 2014, though modern processors achieve far better performance at similar or lower power.
Specialized Performance
AI / ML
- 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
- No AI acceleration hardware
- Low clock speeds further reduce any AVX2 compute capability

Content Creation
Gaming
- 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
- 2.0 GHz base clock too low for consistent game performance
- 3.0 GHz turbo helps in short bursts but cannot sustain
- Only suitable for pre-2015 games at low settings
- HD 4600 insufficient for any modern gaming without a dGPU
- Even with a dGPU, CPU bottleneck is severe in modern titles

Our Verdict on Each
The 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
Read the full reviewAn impressive engineering exercise in power efficiency that sacrificed significant performance for its 35W TDP. Ideal for thermally constrained builds of its era, but modern low-power CPUs deliver far better performance at similar power envelopes.
Best for: Replacing a failed CPU in an existing thin mini-ITX or all-in-one system that requires a 35W LGA 1150 processor
