CPU Comparison
Intel Core i5-6500 vs Intel Core i5-4590
A side-by-side comparison of specs, performance and value. The Intel Core i5-6500 is a 6th generation Skylake quad-core processor designed for mainstream desktop users, offering solid base performance and DDR4 memory support without the premium of an unlocked multiplier.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Lacks the thread count for modern multi-tasking and rendering workloads.
Adequate for basic office tasks. The 3.7 GHz turbo helps with bursty single-threaded workloads like application launches.
Gaming
Bottlenecks modern GPUs heavily in newer titles; fine for older or esports games.
The 3.7 GHz turbo helps in older and eSports titles, but four threads remain a hard ceiling for modern gaming workloads.
Virtualization
Very limited for running VMs due to 4 threads.
Four threads are insufficient for practical virtualization despite VT-x and VT-d support.
Efficiency
65W TDP is easy to cool and fairly efficient for a 14nm quad-core.
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
- 4 threads severely limit local LLM and inference capabilities
- 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
- Severe 1% low frame drops in modern CPU-heavy games
- Adequate for CS:GO and Valorant
- No overclocking headroom to alleviate bottlenecks
- Best gaming CPU in the standard Haswell i5 lineup at launch

Our Verdict on Each
A reliable workhorse in its day, the i5-6500 delivered excellent value for locked mainstream builds, though its 4-thread limitation renders it obsolete for modern heavy workloads.
Best for: The i5-6500 is only viable today if you are repairing an older LGA 1151 system on an extreme budget or building a basic home server. It can handle web browsing, office applications, and retro or esports gaming adequately. However, buying one new or even used at a high price makes no sense. Modern entry-level chips like the i3-12100F obliterate it in single-core and multi-core performance while offering a modern platform with an upgrade path. If you already own this chip, keep it as long as your tasks remain basic, but do not invest money into this platform expecting a noticeable uplift over your existing setup without moving to a newer generation.
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
