What the Core Ultra 5 245HX is
The Intel Core Ultra 5 245HX is the higher-clock 14-core member of the Arrow Lake-HX mobile stack on BGA 2114. It runs 14 cores at 3.1 GHz Performance-core base with boost to 5.1 GHz alongside 2.6 GHz Efficient-core base to 4.5 GHz, backed by 24 MB of Intel Smart Cache plus 26 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.
Fourteen desktop-derived cores suit entry gaming notebooks and creator laptops where high P-core clocks matter more than maximum thread count. The 3.1 GHz P-core base is the highest in the HX batch, so sustained single-threaded work stays fast under cooling, while bursts to 5.1 GHz clear interactive spikes. Platform AI throughput of 27 TOPS covers on-device assistance beside CPU and GPU.
Against the 14-core Intel Core Ultra 5 235HX below it, the 245HX adds P-core base frequency at identical core counts. Against the 20-core Intel Core Ultra 7 255HX above it, the 245HX trades cores for clocks at a lower price. 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 245HX 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. 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. Two channels keep 14 cores supplied in gaming and creation 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.
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. Minimum assured power of 45 W keeps the chip usable in thinner HX chassis with reduced sustained clocks.
Upgrade paths
On the same package, the path up from the 245HX starts with the 20-core Intel Core Ultra 7 255HX for more cores on BGA 2114 where cooling allows. The 20-core Intel Core Ultra 7 265HX follows for higher clocks. Each move needs a chassis with matching thermal headroom.
The step down to the 14-core Intel Core Ultra 5 235HX keeps the same cores at a lower base for a lower price. A move to BGA 2049 Arrow Lake-H is a different soldered platform with lower power for thin laptops. That change means a whole new system.
Frequently asked questions
What socket does the Intel Core Ultra 5 245HX use?
BGA 2114 (FCBGA2114), the soldered 2,114-ball package for Arrow Lake-HX parts. The chip cannot be removed, so the laptop is chosen with the final CPU.
How are the 14 cores of the 245HX arranged?
Six Lion Cove Performance-cores plus 8 Skymont Efficient-cores with no low-power island cores, giving 14 cores and 14 threads. There is no Hyper-Threading, so each core runs one thread.
What memory does the 245HX need?
DDR5 up to 6400 MT/s in two channels. Exact speeds and capacity follow the laptop design.
Can the 245HX be overclocked?
Yes, the multiplier is unlocked, which permits overclocking where the laptop firmware exposes it. Sustained clocks still follow the cooling and the 160 W turbo limit.
