Summary

The Intel Core 5 120 is a rebranded i5-12400, an Alder Lake 6+0 die that Intel has quietly relaunched under its new Core naming scheme for LGA1700 boards. Reddit sentiment is largely cynical — most enthusiasts immediately recognized it as a years-old chip with a 100 MHz clock bump and a fresh sticker. That said, the underlying 12400 silicon has always been respected as a capable budget gaming chip, and the Core 5 120 inherits that reputation. It's best viewed as a drop-in upgrade option for existing LGA1700 owners on DDR4, not a compelling choice for new builds in 2025. The pricing controversy is real — early retailer listings at $216+ drew heavy criticism given the original 12400F still sells for around $100.

Pros

Proven Alder Lake 6P/12T core design with no E-core thread scheduling headaches — a genuine plus for gaming workloads where Windows has historically mismanaged hybrid architectures
Drop-in upgrade for LGA1700 DDR4 systems — no new motherboard or RAM required, which keeps total upgrade cost low for people already on 12th gen platforms
Low memory latency from its monolithic die gives it a small but real edge over Zen 4 in certain CPU-sensitive titles like Stalker 2
The non-F variant (Core 5 120) retains integrated graphics, making it more versatile for OEM builds and systems without discrete GPUs
Mature platform support — LGA1700 ecosystem is well-understood, widely available used, and boards are cheap on the secondary market

Cons

Effectively identical to the i5-12400F which launched in 2021 — the only change is a 100 MHz boost clock increase, making this a branding exercise more than a product launch
Early retailer pricing at $216–$246 is hard to justify when the 12400F sits around $100 and the 14400F can be had for $150 — the value case collapses unless pricing normalizes significantly
Only 18MB of L3 cache is notably limited for 2025, especially against AMD's cache-heavy budget stack including the 5800X3D and upcoming AM4 X3D chips
LGA1700 is a dead-end socket — Intel has confirmed it's being retired, making any investment here a stopgap with no upgrade path
For new builders, AMD's AM5 budget lineup (7500F, 7600, 9600) offers better value with a viable upgrade path, making the Core 5 120 a tough sell outside of existing platform upgrades

LGA1700 Owners: The Only People Who Should Care About This CPU

Reddit consensus is clear — the Core 5 120 is not for new builders. Its real audience is the surprisingly large segment of users still running 12th gen with DDR4 who want a modest bump without platform migration costs. For everyone else, AMD offers a better path.

Is Intel Charging a Rebrand Tax?

The controversy isn't the chip — it's the price. Enthusiasts on r/intel pointed out that early listings at $216+ border on absurd when functionally identical silicon is available for half the cost. Intel may be betting on brand confusion to justify the premium.

The 12400 Was Actually Good — And That's Still True

Buried under the rebrand outrage is a quieter thread of users defending the core silicon. Low latency, no E-core drama, solid 1080p gaming — the 12400's reputation holds up. The Core 5 120 inherits all of that, for better or worse.

It makes sense as a lot of system assemblers are still using the 12400f due to price, but with the DDR4 price hike in may and June, it's a system that is hard to sell, and the fact that SI's can use one main board for their production of Intel PCs makes it cheaper for them to stock.
