Intel has launched a new two-part refresh of its Core Ultra Series 2 Arrow Lake family of desktop processors, headlined by the Core Ultra 7 270K Plus. The release, which also includes the Core Ultra 5 250K Plus, brings increased CPU core counts, more L3 cache, minor increases in clock speeds, and faster uncore frequencies compared to existing models.
The 2026 Arrow Lake refresh addresses thread count shortfalls from the previous generation. While the initial Arrow Lake processors featured IPC increases on E-cores and energy efficiency gains via a TSMC 3-nanometer node, the lack of Hyper-Threading on the new Lion Cove P-cores reduced overall thread counts. Intel’s new SKUs attempt to fix this by increasing the core counts over the chips they replace.
As the high-end model in the new lineup, the Core Ultra 7 270K Plus offers eight P-Cores and sixteen E-Cores, totaling 24 threads without Hyper-Threading. This mirrors the core configuration of the more expensive Core Ultra 9 285K. The underlying Arrow Lake architecture remains unchanged, but Intel has improved memory compatibility and link speeds between the CPU dies.
Application performance for the Core Ultra 7 270K Plus surpasses the Core Ultra 9 285K, though the 285K still leads in select tests due to a higher maximum boost frequency. The 270K Plus beats all AMD CPUs in application workloads, with the exception of the $515 Ryzen 9950X and the $675 Ryzen 9950X3D. Additionally, all Arrow Lake processors feature an NPU to accelerate AI workloads, a capability not present on AMD’s AM5 platform.
In terms of gaming, the Core Ultra 7 270K Plus is faster than the Core i9-14900K and the Core Ultra 9 285K. It outperforms every AMD processor in gaming scenarios outside of the Ryzen X3D models. The AMD Ryzen 7 9800X3D is 15 percent faster on average, but it costs $420, whereas the 270K Plus is priced at $300 and delivers superior application performance.
The processor utilizes a revamped integrated graphics unit introduced with the Core Ultra 200 Series. The iGPU doubles the performance of the older Raptor Lake processors, handling light gaming, productivity tasks, and accelerated video playback through wide codec support and Quick Sync.
Power consumption for the 270K Plus averages 140 watts in application tests, which is comparable to the 285K. Gaming power consumption sits at 110 watts. Cooling the processor is manageable with a standard air cooler, as the heat output is lower and spread out over a larger area across the P-Cores. Intel’s 105-degree Celsius thermal limit allows for additional headroom while maintaining a full warranty for continuous use.
Overclocking potential on the 270K Plus is present but somewhat limited, as the processor is already pushed near its maximum out of the box. All cores reached 5.6 GHz, which is 100 MHz above the rated 5.5 GHz maximum boost on up to two cores. The E-Cores reached 5.1 GHz, exceeding their rated maximum by 400 MHz. Overclocking requires an expensive Z890 motherboard, as Intel locks the feature behind its top chipset.
Alongside the hardware, Intel introduced a new software update called Intel Binary Optimization. This software optimizes applications as they load, aiming to introduce performance gains in gaming without requiring time-intensive optimization from developers.
Priced aggressively at $300, the Core Ultra 7 270K Plus competes directly with the $305 AMD Ryzen 7 9700X, which offers slightly lower gaming and significantly lower application performance. However, the LGA1851 socket used by Arrow Lake is at the end of its line, meaning future upgrades will require a new motherboard.
