Specifications
Performance
Handles typical office tasks and light creative workloads well; multi‑threaded exports benefit from six real cores and SMT, but larger caches and more cores on higher‑end parts reduce render times noticeably.
Provides playable frame rates at 1080p in most modern titles when paired with a mid‑range GPU; expect some CPU‑limited scenarios at 144 Hz in CPU‑heavy games, where CPUs with higher boost clocks or E‑cores can pull ahead.
The 65 W base power keeps idle and light‑load power modest; under multi‑threaded loads the 110 W MTP is reasonable for six cores, yielding acceptable performance per watt for this price segment.
- •Six P‑cores and 4.5 GHz max turbo are sufficient for most 1080p gaming workloads.
- •Limited by lack of E‑cores in extremely parallel game engines compared to 10‑core Raptor Lake options.
- •iGPU (UHD 730) is only suitable for very light or older games; discrete GPU is recommended for serious gaming.
- •No discrete NPU; AI workloads run on CPU cores using AVX2/AVX and Intel DL Boost where applicable.
- •Suitable for small inference tasks and local prototyping; not ideal for training or large models compared to NPUs or GPUs.

- 65 W base power keeps cooling requirements modest; stock RM1 cooler is usable for light workloads.
- At $211 RCP, pricing is competitive for a new six‑core part.
- No E‑cores; in highly threaded games or productivity tasks, 10‑core Raptor Lake‑Refresh SKUs can outperform it.
- Reuses Alder Lake silicon, so it lacks architectural improvements found in Raptor Lake or Arrow Lake.
- Locked multiplier limits enthusiast overclocking.
- The Core (Series 1) naming can confuse buyers who expect a newer microarchitecture.
- Intel’s 600/700 chipsets are mature; the platform has no upgrade path to LGA1851.
History
Intel introduced the Core 5 120 in mid‑2025 as part of the new Core (Series 1) branding. Under the hood, it’s a 6+0 Alder Lake‑S die (H0 stepping) with a 100 MHz higher turbo than the 2022 i5‑12400 and a slightly lower 110 W MTP. The move drew attention because the underlying silicon predates Raptor Lake and Arrow Lake; coverage by Tom’s Hardware and VideoCardz framed it as a rebadged i5‑12400.
Intel ARK lists the part under 'Products formerly Raptor Lake' with a Q3’25 launch date, and Tom’s Hardware reports availability on July 31, 2025. The strategy lets Intel continue monetizing mature Alder Lake die inventory while simplifying the Core branding lineup alongside Core Ultra 200S (Arrow Lake).
Improvements over Previous Generation
- +100 MHz higher max turbo (4.5 GHz vs 4.4 GHz).
- Reduced Maximum Turbo Power (110 W vs 117 W) for slightly lower turbo power headroom, which may marginally affect sustained multi‑thread boosts.
- Updated branding under Core (Series 1) and alignment with Intel’s current naming scheme.
Alternatives & Competitors
Should You Buy It?
Recommended for the right buyer
Budget gaming or general‑purpose build on an existing LGA1700 (600/700 series) board where you want a drop‑in six‑core upgrade with DDR5 support and don’t need more than 1080p gaming.
Avoid if…
- You need high‑refresh 1440p+ gaming with heavy CPU loads.
- You want a forward‑looking upgrade path beyond LGA1700.
- You already own an i5‑12400/12400 and don’t need the small turbo bump.
- You prioritize multithread productivity; consider 10‑core options or AMD’s AM4/AM5 six‑core parts for better value.
Use Cases
Interesting Facts
The Core 5 120 uses the Alder Lake H0 die, a 6P+0E configuration originally introduced with 12th‑gen parts, and Intel ARK lists it under 'Products formerly Raptor Lake.'
Tom’s Hardware and VideoCardz report that the Core 5 120 is essentially a rebadged i5‑12400 with a +100 MHz turbo (4.5 GHz) and a reduced MTP of 110 W (down from 117 W on the 12400).
The Alder Lake H0 six‑core die measures approximately 163 mm², making it significantly smaller than the 8P+8E C0 die (roughly 215 mm²).
