CPU Comparison
Intel Core 5 120HL vs Core i5-12400T
A side-by-side comparison of specs, performance and value. A 12-core/16-thread Raptor Lake-PS processor in LGA1700 with an 80 EU Iris Xe iGPU, 45 W base power, Gen4 CPU PCIe, dual-channel DDR4/DDR5, and a 10-year embedded lifecycle—targeted at edge devices, kiosks, digital signage, and other long-life systems rather than consumer DIY gaming PCs.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
12 cores/16 threads handle office multitasking and light-to-moderate productivity well, though lower clocks and 95 W max power constrain sustained heavy workloads.
Highly responsive for daily applications and moderate multitasking.
Gaming
Serviceable for esports or casual games at 1080p low-to-medium when paired with a discrete GPU; iGPU alone is insufficient for most modern AAA titles.
Decent for gaming with a discrete GPU, though limited by lower max boost compared to 65W variants.
Virtualization
E-cores help run multiple VMs, but the 45–95 W power envelope and memory ceiling (96 GB) limit large-scale virtualization compared to higher-tier desktop parts.
6 cores with 12 threads handle homelab virtualization well.
Efficiency
45 W base power and an E-core-heavy mix provide reasonable efficiency at idle and light loads; higher-power Raptor Lake SKUs will outrun it under sustained multi-thread load.
Near-perfect efficiency for a desktop chip; runs exceptionally cool.
Specialized Performance
AI / ML
- Intel DL Boost (VNNI) on CPU supports basic inference workloads.
- No discrete NPU; GPU does not have DL Boost according to ARK.
- Suitable for small edge models and vision pipelines, not large-scale training.
- No dedicated AI hardware
- CPU-based AI inference is slow
Content Creation
Gaming
- iGPU with 80 EUs is adequate for legacy or light games, not modern AAA.
- CPU-side performance is comparable to entry 12th/13th Gen i5 parts; acceptable when paired with a midrange GPU for 1080p.
- Not marketed as a gaming SKU; best suited to embedded or light-use systems.
- Requires a discrete GPU for serious gaming
- Slightly lower FPS than 12400 due to clocks
- Excellent for living room gaming setups

Target Audience
Strengths & Weaknesses
Pros
- 12 cores (4P + 8E) and 16 threads for good multi-tasking in embedded settings.
- 80 EU Iris Xe iGPU with AV1 decode and Quick Sync; supports up to four displays.
- 10-year embedded lifecycle from Q2’24 simplifies long-term product planning.
- 45 W base and 35–95 W power envelope fits small enclosures and fanless designs.
- Dual-channel DDR4/DDR5 support gives OEMs flexibility in BOM cost versus bandwidth.
- Intel vPro Essentials and robust security features (TXT, CET, TDT, VT-x/VT-d).
- LGA1700 uses familiar 600/700-series chipsets, reducing design risk for edge platforms.
Cons
- Not targeted at the DIY gaming market; limited retail availability as a boxed part.
- Multiplier locked and limited to 95 W max turbo; lower peak performance vs 125W+ desktop SKUs.
- No ECC memory support according to ARK.
- CPU iGPU lacks DL Boost; GPU AI acceleration is limited.
- PCIe allocation (CPU vs PCH lane count) is not explicitly detailed on ARK for this SKU.
- Naming and segmentation (Core Series 1, PS, Embedded) can cause confusion versus consumer Raptor Lake parts.
Pros
- Extremely low 35W TDP
- Pure P-core design
- PCIe 5.0 support
- Runs very cool
- DDR5 support
Cons
- Lower boost clocks than 12400
- Locked multiplier
- UHD 730 graphics are basic
- Harder to find than standard models
- PL2 drops quickly to 35W

Our Verdict on Each
The Core 5 120HL is not a typical gaming or overclocking chip. Its value lies in the 10-year embedded supply commitment, competent 12C/16T performance, 45 W base power envelope, and flexible I/O with Gen4 CPU PCIe and Gen3 chipset lanes. For OEMs building edge appliances or long-lifecycle desktops on LGA1700, it is a practical choice; for mainstream gamers or enthusiasts, standard Raptor Lake/K-series SKUs are more appropriate.
Best for: OEMs and system integrators building long-lifecycle edge appliances, kiosks, POS systems, or light-office desktops on LGA1700 that need 10-year supply stability and iGPU-accelerated media.
