Intel’s next desktop refresh is taking shape, and the story is all about “Plus” branding, extra E-cores where it counts, modest P-core clock bumps, and faster memory support. Fresh leaks suggest the Arrow Lake Refresh lineup will introduce Core Ultra 9 290K Plus, Core Ultra 7 270K Plus, and Core Ultra 5 250K Plus models with targeted upgrades over their predecessors.
What’s changing at a glance
– Plus branding across select Arrow Lake Refresh SKUs
– Extra E-cores for Core Ultra 7 270K Plus and Core Ultra 5 250K Plus
– Up to a 100 MHz bump to P-core max frequency on select parts
– Higher Thermal Velocity Boost on the flagship
– Official DDR5-7200 support across the refresh (up from DDR5-6400)
Core Ultra 9 290K Plus
– Replaces the Core Ultra 9 285K
– Core configuration: 8 P-cores + 16 E-cores (unchanged)
– Performance uplift: around +100 MHz to max P-core frequency and a higher Thermal Velocity Boost ceiling, reportedly up to 5.8 GHz
– Memory: official DDR5-7200 support
– Power targets expected to remain in the 125W base, 250W turbo class typical for unlocked K-flagship chips
Takeaway: This is a refinement of an already high-end part, focusing on slightly higher top clocks and faster memory rather than a core count change.
Core Ultra 7 270K Plus
– Replaces the Core Ultra 7 265K
– Core configuration: 8 P-cores + 16 E-cores, adding four E-cores for a total of 24 cores
– Clocks: broadly similar to the 265K on the P-core side, with E-core clocks adjusted as part of the refresh
– Memory: official DDR5-7200 support
Takeaway: This mirrors a familiar strategy from previous refresh cycles where the i7-class chip receives the most meaningful core count bump, translating to stronger multi-threaded performance for creators and power users.
Core Ultra 5 250K Plus
– Sits above the Core Ultra 5 245K
– Core configuration: 6 P-cores + 12 E-cores, adding four E-cores for 18 total cores
– Performance uplift: about +100 MHz to max P-core frequency compared to its predecessor
– Memory: official DDR5-7200 support
– Power: expected 125W base with a more moderate turbo limit than the higher tiers
Takeaway: A compelling mainstream upgrade that blends better multi-thread throughput from the added E-cores with a small single-thread boost, making it attractive for gaming and mixed workloads.
Why DDR5-7200 matters
The refresh’s move to official DDR5-7200 support is an 800 MT/s jump over current non-Plus models. Arrow Lake’s memory controller is already regarded as strong; formalizing higher speeds should improve bandwidth in memory-sensitive tasks and give overclockers more headroom, all while broadening plug-and-play compatibility for fast DDR5 kits.
Positioning and expectations
– Core Ultra 9 290K Plus: incremental uplift for top-end enthusiasts
– Core Ultra 7 270K Plus: the sweet spot upgrade with a sizable E-core increase
– Core Ultra 5 250K Plus: mainstream value with more cores and a small clock bump
Pricing and exact availability remain to be confirmed. As with any pre-launch leak, final specifications can shift, but the pattern is clear: more E-cores where it drives real-world gains, slightly faster P-core peaks for snappier single-thread performance, and a welcome step forward in official DDR5 memory speeds. For builders planning a new rig or an upgrade path, the Plus refresh looks tuned to deliver better multi-threaded performance and memory bandwidth without changing platforms.
