CPU Comparison
Core i5-3450 vs Intel Core i5-4590
A side-by-side comparison of specs, performance and value. The Intel Core i5-3450 is a mainstream desktop processor launched in April 2012 as part of the Ivy Bridge architecture. Designed for the LGA 1155 socket, it brought the 22nm manufacturing process to the masses, offering a significant efficiency improvement over Sandy Bridge. This quad-core processor operates at a base frequency of 3.1 GHz and boosts up to 3.5 GHz. It features 6MB of L3 cache and supports dual-channel DDR3-1600 memory. The inclusion of Intel HD 2500 integrated graphics provided basic display capabilities, though it was not intended for gaming. With a 77W TDP, it balanced power consumption and performance adequately for its time. While it lacks Hyper-Threading and an unlocked multiplier, it became a favorite for budget builders and system integrators, providing reliable performance for everyday computing and gaming when paired with a dedicated GPU.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Can handle basic document editing, but struggles with heavy multitasking or modern web apps.
Adequate for basic office tasks. The 3.7 GHz turbo helps with bursty single-threaded workloads like application launches.
Gaming
Severely bottlenecks modern GPUs. Only viable for pre-2015 games at low settings.
The 3.7 GHz turbo helps in older and eSports titles, but four threads remain a hard ceiling for modern gaming workloads.
Virtualization
Limited to very light virtualization due to lack of Hyper-Threading.
Four threads are insufficient for practical virtualization despite VT-x and VT-d support.
Efficiency
Efficient for its era, but completely outclassed by modern 10nm and 7nm processors.
84W for this performance is unimpressive by modern standards. Competing architectures now deliver 3x the performance per watt.
Specialized Performance
AI / ML
- No AI hardware acceleration
- AVX instructions present but too slow for modern AI
- 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
- Low clock speeds limit frame rates
- 4 cores cause stuttering in modern games
- HD 2500 graphics are useless for 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
