Intel’s Arrow Lake Refresh Landing Mid-March: More Cores, Faster RAM, No Flagship
Intel is preparing to launch its anticipated mid-cycle desktop update, the Core Ultra 200K “Plus” series, better known by its codename “Arrow Lake Refresh.” According to reports from multiple hardware outlets, citing information from VideoCardz, the official unveiling is scheduled for Wednesday, March 11, with a full performance review embargo (NDA) lifting on Monday, March 23.
This timing confirms a March-to-April launch window for both the new desktop “K Plus” processors and their mobile “HX Plus” counterparts. However, the launch lineup looks a bit different than initially expected.
The Lineup: No Core Ultra 9, Focus on the Mid-Range
The most significant shift in Intel’s plans is the reported cancellation of the flagship Core Ultra 9 290K Plus. Rumors suggest the chip was scrapped because it offered virtually no generational improvement over the existing Core Ultra 9 285K, lacking the core count bump seen on the lower-tier models.
This leaves the spotlight on two main desktop SKUs :
- Core Ultra 7 270K Plus: The new headliner of the refresh.
- Core Ultra 5 250K Plus: The value-oriented option.
What’s Changing? Small Bumps, Bigger E-Cores
The “Refresh” moniker is fitting, as changes are incremental but welcome. The primary hardware upgrade for these two chips is an increase in their Efficiency-core (E-core) counts, which should boost multi-threaded performance in productivity tasks.
Here is how the new “Plus” models stack up against their predecessors:
| Model | Cores (P+E) | Max Turbo | Memory Support (Official) |
|---|---|---|---|
| Core Ultra 7 270K Plus | 8P + 16E (↑4 E-cores) | 5.5 GHz | DDR5-7200 CUDIMM (↑) |
| Core Ultra 7 265K | 8P + 12E | 5.5 GHz | DDR5-6400 |
| Core Ultra 5 250K Plus | 6P + 12E (↑4 E-cores) | 5.3 GHz | DDR5-7200 CUDIMM (↑) |
| Core Ultra 5 245K | 6P + 8E | 5.2 GHz | DDR5-6400 |
The Star of the Show: Faster RAM
Beyond the core counts, the defining feature of the Arrow Lake Refresh is its official support for faster memory. Both new processors will natively support DDR5-7200 CUDIMMs (Clocked Unbuffered Dual In-line Memory Modules).

This jump from the previous 6400 MT/s support ensures better stability and performance for high-frequency memory kits right out of the box, without relying on motherboard overclocking profiles. While enthusiasts have already been pushing memory speeds higher, this official bump solidifies the standard for the LGA1851 platform.
For now, the rumor mill points to a modest but meaningful update for users looking to squeeze more life out of the LGA1851 socket before the expected arrival of the next-generation Nova Lake platform.
