Intel Core Ultra 7 265HX socket: BGA 2114

What the Core Ultra 7 265HX is

The Intel Core Ultra 7 265HX is the higher-clock 20-core member of the Arrow Lake-HX mobile stack on BGA 2114. It runs 20 cores at 2.6 GHz Performance-core base with boost to 5.3 GHz alongside 2.3 GHz Efficient-core base to 4.6 GHz, backed by 30 MB of Intel Smart Cache plus 36 MB of L2 and a 55 W base power with 160 W maximum turbo power. Intel launched the HX range in January 2025, building the compute tile on TSMC 3 nm with 17.8 billion transistors on a 243 square millimeter die.

Twenty desktop-derived cores suit performance gaming notebooks, creator laptops and portable workstations that need strong parallel throughput without the top Ultra 9 price. The 2.6 GHz P-core base keeps sustained work moving under full cooling, while bursts to 5.3 GHz clear single-threaded spikes. An AI Boost NPU with 13 TOPS backs 33 platform TOPS for on-device assistance beside CPU and GPU.

Against the 20-core Intel Core Ultra 7 255HX below it, the 265HX adds base frequency across both core types at identical core counts. Against the 24-core Intel Core Ultra 9 275HX above it, the 265HX trims 4 E-cores for slimmer chassis. Unlocked multipliers invite tuning where firmware allows. See CPU cooler compatibility by socket for how soldered mobile cooling differs from socketed desktops.

Socket and motherboard compatibility

The 265HX fits BGA 2114, a 2,114-ball soldered package measuring 37.5 × 30.2 mm. The chip is soldered once at the factory and stays with the board for life, so there is no retention mechanism and no aftermarket mounting choice. Cooling is part of the laptop design for the 55 W base with 160 W turbo headroom and a 105 degree junction limit, usually dual-fan heat pipe assemblies.

Board choice means laptop choice. Memory is DDR5 up to 6400 MT/s in two channels, and the chipset rides alongside as WM880 or HM870 depending on the design. A chassis revision needs firmware that knows the Arrow Lake-HX stepping. Moving from any other package is a full system change with memory and thermal design replaced together.

Memory, PCIe and cooling

Memory on BGA 2114 is DDR5 up to 6400 MT/s in two channels with up to 102.4 GB per second of bandwidth. Two channels keep 20 cores supplied in gaming, streaming and compilation mixes where the working set fits laptop memory sizes. Capacity and ECC behavior follow the laptop spec sheet, so buyers confirm each model.

PCI Express connectivity is Gen 5 with x20 lanes from the CPU plus x4 Gen 4 lanes for board devices. That lane budget feeds discrete graphics over a Gen 5 x16 link plus NVMe storage without strain. Lane splits between graphics, NVMe and Thunderbolt follow the board layout, so buyers confirm slot wiring before counting on multi-drive arrays.

Graphics come from Arc Xe-LPG with 64 execution units, enough for control displays and light play, while gaming designs add discrete graphics. Cooling follows the maker specification for the 55 W class with 160 W turbo headroom. Firmware power limits can cap draw below the default in quieter profiles, at some cost in sustained clocks.

Upgrade paths

On the same package, the path up from the 265HX starts with the 24-core Intel Core Ultra 9 275HX for more E-cores on BGA 2114 where cooling allows. The flagship Intel Core Ultra 9 285HX follows for top-bin clocks. Each move needs a chassis with matching thermal headroom.

The step down to the 20-core Intel Core Ultra 7 255HX keeps the same cores at lower clocks for a lower price. A move to BGA 2049 Arrow Lake-H is a different soldered platform with fewer cores and lower power for thin laptops. That change means a whole new system.
