CPU Comparison
Intel Core i3-8100 vs Intel Core i3-8300T
A side-by-side comparison of specs, performance and value. The Intel Core i3-8100 is a historically significant 8th-generation desktop processor that introduced 4 physical cores to the mainstream i3 tier, replacing the dual-core designs of previous generations.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
The lack of Hyper-Threading severely limits performance in heavily threaded office applications compared to newer 8-thread budget chips.
The larger cache makes desktop interactions and application loading feel slightly snappier than the 6MB 8100T.
Gaming
Paired with a strong discrete GPU, it can still handle older eSports titles, but modern AAA games will be heavily CPU bottlenecked.
The 8MB cache helps slightly, but the lack of Turbo Boost and Hyper-Threading makes it unsuitable for gaming.
Virtualization
4 threads is the absolute minimum for running a modern OS and a single light virtual machine.
8MB cache helps with VM context switching, but 4 threads is still a severe bottleneck.
Efficiency
The 14nm process is power-hungry compared to modern 7nm or 5nm alternatives, drawing 65W for modest performance.
Matches the i3-8100T's excellent efficiency profile.
Specialized Performance
AI / ML
- No AI hardware acceleration
- Lacks AVX-512
- Far too slow for any practical AI inference
- No AI hardware.
- Fixed 3.2 GHz clock is too slow for meaningful inference.
Content Creation
Gaming
- Requires a dedicated GPU for any gaming
- Fixed clock speed prevents single-thread boosts
- 4 cores are becoming the bare minimum for modern games
- Not intended for gaming.
- Fixed 3.2 GHz clock prevents acceptable frame rates in modern titles.

Our Verdict on Each
A 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.
Read the full reviewA uniquely configured OEM chip that offers more cache than the retail i3-8100T. While still limited by no Turbo Boost or Hyper-Threading, the 8MB cache makes it the best performing 35W 8th gen i3.
Best for: Finding one salvaged from an OEM PC to use as a cheap LGA 1151v2 upgrade, as it outperforms the retail i3-8100T.
