CPU Comparison
Intel Core i3-8100T vs Intel Core i3-9000
A side-by-side comparison of specs, performance and value. The Intel Core i3-8100T is a 35W, 4-core, 4-thread desktop processor lacking both Hyper-Threading and Turbo Boost, designed specifically for small form factor and low-noise OEM desktop PCs.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
4 cores handle standard office suites well, but heavy Excel macros or large datasets will show the lack of Turbo Boost.
Can handle single applications well due to the high 3.7 GHz clock, but multitasking is severely hindered by 4 threads.
Gaming
The locked 3.1 GHz clock prevents playable frame rates in modern CPU-heavy games, and OEM systems rarely include a GPU.
Even with a dedicated GPU, the lack of Hyper-Threading will cause severe stuttering in modern CPU-bound games.
Virtualization
4 threads without Hyper-Threading is the absolute minimum for any VM usage.
4 threads are the absolute minimum for a host OS, leaving no room for a useful virtual machine.
Efficiency
Very efficient due to the low 35W TDP and lack of power-hungry turbo frequency spikes.
The 14nm process is power-hungry compared to modern alternatives, drawing 65W for mediocre performance.
Specialized Performance
AI / ML
- No AI hardware.
- Fixed 3.1 GHz clock provides poor inference performance.
- Lacks AVX-512 and any modern AI acceleration capabilities
Content Creation
Gaming
- Fixed 3.1 GHz clock is too low for modern games.
- No Hyper-Threading limits background task handling.
- UHD 630 is not for gaming.
- Modern games require at least 8 threads to avoid stuttering
- The fixed 3.7 GHz clock prevents the CPU from boosting during heavy gaming loads

Target Audience
Strengths & Weaknesses
Pros
- Very low 35W power draw
- Predictable, constant 3.1 GHz performance
- 4 physical cores for multitasking
- Includes UHD 630 for display outputs
- Can be configured down to 25W
Cons
- No Turbo Boost (locked at 3.1 GHz)
- No Hyper-Threading (4 cores = 4 threads)
- Low 72°C Tcase limit restricts cooler options
- DDR4-2400 memory speed limit
- Outdated 14nm process
- Only PCIe 3.0
Pros
- High fixed 3.7 GHz clock provides consistent single-thread performance
- 65W TDP is easy to cool
- 16 PCIe 3.0 lanes are sufficient for basic add-in cards
- Uses mature, inexpensive LGA 1151 motherboard chipsets
Cons
- No Hyper-Threading limits it to 4 threads, which is unacceptable today
- No integrated graphics means a dead system if the dGPU fails
- No Turbo Boost technology
- Locked to DDR4-2666 memory speeds
- Dead-end LGA 1151 platform with no upgrade path

Our Verdict on Each
A product of Intel's core-count strategy, the i3-8100T traded clock speed and threading for low heat output. It was adequate for basic office work in tiny chassis but aged rapidly due to its lack of Turbo Boost.
Best for: Only if you are repairing an existing SFF PC and can find the chip for under $15 on the used market.
Read the full reviewThe i3-9000 is a heavily segmented OEM chip that removed Hyper-Threading and integrated graphics. It has no place in the modern computing landscape.
Best for: The only acceptable scenario for the i3-9000 is if you inherit a pre-built office PC for free and need a basic machine to run a legacy piece of software or act as a home file server. Because it lacks an iGPU, you must ensure it has a dedicated graphics card installed, or it will not output video. Do not spend money acquiring this processor.
