CPU Comparison
Intel Core i5-4440S vs Intel Core i3-8100
A side-by-side comparison of specs, performance and value. The Intel Core i5-4440S is a 4-core, 4-thread desktop processor launched in September 2013 as part of the Haswell generation. Operating on a 22nm manufacturing process, this CPU was designed for budget-conscious builders who needed reliable performance without the high power draw. With a base clock of 2.8 GHz and a turbo boost of up to 3.3 GHz, it delivered solid everyday computing and moderate multitasking capabilities. The 'S' suffix denotes a lower power profile, locking the TDP at 65 watts compared to the standard 84-watt models. This made it an ideal choice for small form factor builds and office environments where thermal management was crucial. It includes Intel HD 4600 integrated graphics, allowing for media playback and light gaming without a dedicated GPU. Although long surpassed by modern standards, it remains a notable example of Intel's efficiency-focused engineering during the early 2010s.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles basic office tasks well but struggles with heavy multitasking.
The lack of Hyper-Threading severely limits performance in heavily threaded office applications compared to newer 8-thread budget chips.
Gaming
Bottlenecks modern GPUs; suitable only for older titles.
Paired with a strong discrete GPU, it can still handle older eSports titles, but modern AAA games will be heavily CPU bottlenecked.
Virtualization
Limited to very light VM usage due to 4 threads.
4 threads is the absolute minimum for running a modern OS and a single light virtual machine.
Efficiency
Good efficiency for its era thanks to the 65W TDP.
The 14nm process is power-hungry compared to modern 7nm or 5nm alternatives, drawing 65W for modest performance.
Specialized Performance
AI / ML
- No dedicated AI hardware
- Extremely slow for modern AI inference
- No AI hardware acceleration
- Lacks AVX-512
- Far too slow for any practical AI inference
Content Creation
Gaming
- Requires a dedicated GPU for any 3D workloads
- Will severely bottleneck modern mid-range GPUs
- Capable of running CS:GO and older source engine games
- Requires a dedicated GPU for any gaming
- Fixed clock speed prevents single-thread boosts
- 4 cores are becoming the bare minimum for modern games

Our Verdict on Each
A reliable 65W quad-core CPU ideal for basic legacy systems, but obsolete for modern builds.
Best for: Drop-in upgrade for an existing LGA 1150 system.
Read the full reviewA landmark chip in 2017 for bringing quad-core computing to the masses, but thoroughly outclassed by modern budget processors in every metric.
Best for: The only justifiable scenario for purchasing an Intel Core i3-8100 today is if you are repairing an existing LGA 1151 v2 system (like an office PC or a hand-me-down) and can find the CPU for under $20 on the used market. Even then, you must consider that the 8100 lacks Hyper-Threading, which severely limits its longevity in modern operating systems that are increasingly optimized for 8 or more threads. If you are building a new system, even the absolute cheapest new motherboard and CPU combo from AMD or Intel's 12th/13th gen will offer exponentially better performance, efficiency, and platform features like PCIe 4.0 or DDR5. Do not buy this CPU for gaming, as the lack of Turbo Boost and Hyper-Threading will cause severe stuttering in modern titles compared to a modern Ryzen 3.
