CPU Comparison
Intel Core i5-3475S vs Intel Core i3-12100
A side-by-side comparison of specs, performance and value. The Intel Core i5-3475S is a 65W quad-core Ivy Bridge desktop processor featuring Intel HD 4000 graphics, offering better GPU performance than the HD 2500-equipped i5-3470S in the same power envelope.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Same CPU performance as the i5-3470S — adequate for basic office work but limited by today's standards.
Handles everyday office tasks and web applications with ease, but heavy multitasking will expose the 4-core limitation.
Gaming
HD 4000 provides noticeably better gaming capability than HD 2500 but is still insufficient for modern titles.
Delivers playable 1080p frame rates in esports and older AAA titles when paired with a mid-range GPU, though 4 cores limit performance in modern CPU-heavy games.
Virtualization
Four cores without Hyper-Threading provide basic virtualization capability.
Can run a single lightweight virtual machine, but lacks the core count for serious virtualization workloads.
Efficiency
The 65W TDP balances power efficiency with the additional GPU capability, reasonable for 2012.
Very power-efficient for a desktop processor, drawing little power at idle and scaling linearly under load.
Specialized Performance
AI / ML
- No AI acceleration hardware
- Not applicable for this processor generation
- Insufficient compute for AI workloads
- No dedicated AI acceleration hardware
- CPU-based inference is slow with only 4 cores
- Not designed or recommended for machine learning tasks
Content Creation
Gaming
- HD 4000 with 16 EUs is the best integrated GPU in the Ivy Bridge i5 desktop lineup
- Can handle older games like Minecraft and Team Fortress 2 at low settings
- GPU shares system memory bandwidth, limiting performance
- Modern gaming still requires a discrete GPU
- Strong single-core performance benefits esports titles significantly
- Bottlenecks appear with GPUs above the RTX 3060 tier in CPU-bound games
- UHD 730 iGPU is insufficient for modern gaming
- 4 cores and 8 threads are the minimum recommended for modern PC gaming

Our Verdict on Each
The i5-3475S stands out as the only 65W quad-core Ivy Bridge i5 with HD 4000 graphics, but its outdated platform still makes it unsuitable for modern builds.
Best for: Maintaining an existing system that relies on integrated graphics without a discrete GPU
Read the full reviewThe i3-12100 delivers exceptional single-threaded performance for its $122 price point, complete with an iGPU and a stock cooler, making it one of the most well-rounded budget desktop processors Intel has ever produced.
Best for: Buy the i3-12100 if you are building a budget desktop PC and want the peace of mind of having integrated graphics as a fallback, or if you do not plan to install a dedicated GPU. At its current street price, it is an excellent choice for office PCs, student workstations, and entry-level gaming rigs paired with a mid-range graphics card like the GTX 1660 Super or RX 6600. Avoid it only if you are certain you will never need the iGPU, as the 12100F offers identical CPU performance for less money.
