CPU Comparison
Intel Core 3 100UL vs Intel Core 5 120HL
A side-by-side comparison of specs, performance and value. The Intel Core 3 100UL is a low-power, LGA1700-socketed embedded/desktop processor with a hybrid 2P+4E configuration, 10 MB L3 cache, and 15 W base power, designed for small-form-factor and edge systems that still need modern connectivity such as PCIe 4.0, Thunderbolt 4, and dual-channel DDR4/DDR5.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles everyday office suites, browsers, and light multitasking well, but long multi-core renders will be slow compared to higher-TDP desktop parts.
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.
Gaming
Occasional esports and very light titles are playable at low settings; this is not intended as a gaming CPU.
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.
Virtualization
Can run a couple of light VMs for testing, but memory bandwidth and core count limit heavy virtualization use.
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.
Efficiency
Excellent efficiency for always-on and fan-constrained designs thanks to the 15 W base power and hybrid architecture.
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.
Specialized Performance
AI / ML
- DL Boost is present on the CPU, but there is no dedicated NPU.
- Suitable only for light CPU-based inference workloads.
- 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.
Content Creation
Gaming
- Only 64 execution units and modest clocks limit 3D performance.
- Playable in older or lightweight esports titles at low resolutions and settings.
- Better suited as a display/compute engine for casual UIs than for 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.

Strengths & Weaknesses
Pros
- Very low 15 W base power with 55 W turbo headroom.
- LGA1700 socket enables field upgrades and reuse of existing boards.
- Hybrid 2P+4E design improves responsiveness and multitasking versus non-hybrid low-power parts.
- Dual-channel DDR4 and DDR5 support provides OEM flexibility.
- UHD Graphics 64 EU with AV1 decode and multi-display (up to 4 displays).
- PCIe 4.0 from the CPU for modern NVMe SSDs.
Cons
- Not suited for gaming or heavy content creation.
- Only 8 threads limit parallel workloads.
- Limited PCIe lanes compared to mainstream desktop CPUs.
- Niche positioning (embedded/edge) means less community documentation.
- No multiplier overclocking.
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.

Our Verdict on Each
The Core 3 100UL is not a gaming or creator powerhouse, but it is a competent, power-frugal hybrid part for embedded and compact desktops. Its mix of LGA1700 upgradability, 15 W base power, modern iGPU with AV1 decode, and flexible DDR4/DDR5 support makes it useful for OEMs and system integrators building low-profile, always-on systems.
Best for: OEM or system integrator building small, low-power embedded or commercial desktops that need LGA1700 field serviceability and multi-display support.
Read the full reviewThe 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.
