Intel Core Ultra 5 235H socket: BGA 2049

What the Core Ultra 5 235H is

The Intel Core Ultra 5 235H is the higher-clock 14-core member of the Arrow Lake-H mobile stack on BGA 2049. It runs 14 cores at 2.4 GHz Performance-core base with boost to 5.0 GHz alongside 1.8 GHz Efficient-core base to 4.4 GHz and 700 MHz low-power base to 2.5 GHz boost, backed by 18 MB of Intel Smart Cache and a 28 W base power. Intel launched the H range in January 2025, building the compute tile on TSMC 3 nm.

Fourteen cores at 28 W suit thin creator laptops and business flagships where responsiveness and graphics matter more than sustained draw. The 2.4 GHz P-core base keeps everyday work fast inside slim cooling, while bursts to 5.0 GHz clear interactive spikes. Platform AI throughput of 94 TOPS covers on-device assistance beside CPU and GPU.

Against the 14-core Intel Core Ultra 5 225H below it, the 235H adds base frequency and steps graphics up to Arc 140T at identical core counts. Against the 16-core Intel Core Ultra 7 255H above it, the 235H trims cores for budget designs. Arc 140T graphics with 8 Xe-cores serve modern play without discrete silicon. See LGA, PGA and BGA: CPU package types explained for how soldered mobile packages differ from socketed desktops.

Socket and motherboard compatibility

The 235H fits BGA 2049, a 2,049-ball soldered package measuring 50 × 25 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 28 W class with turbo headroom and a 110 degree junction limit, usually slim dual-fan assemblies.

Board choice means laptop choice. Memory is LPDDR5X up to 8400 MT/s or DDR5 up to 6400 MT/s in two channels. A chassis revision needs firmware that knows the Arrow Lake-H 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 2049 is LPDDR5X up to 8400 MT/s or DDR5 up to 6400 MT/s in two channels. Soldered LPDDR5X feeds both CPU and Arc graphics with high bandwidth, while DDR5 SODIMM slots keep some designs serviceable. Capacity follows the laptop spec sheet, so buyers confirm each model.

PCI Express connectivity spans PCIe 5.0 and 4.0 for up to 28 lanes plus Thunderbolt 4. That lane budget feeds NVMe storage and compact discrete graphics on gaming designs without strain. Lane splits follow the board layout, so buyers confirm wiring before counting on multi-drive arrays.

Graphics come from Intel Arc 140T with 8 Xe-cores, a tier above the 130T in the 225H for smoother modern play. Cooling follows the maker specification for the 28 W class. Firmware power limits scale the chip down toward its minimum assured power in silent profiles, at some cost in sustained clocks.

Upgrade paths

On the same package, the path up from the 235H starts with the 16-core Intel Core Ultra 7 255H for more cores on BGA 2049 where the budget allows. The 16-core Intel Core Ultra 7 265H follows for higher clocks. Each move needs a chassis with matching thermal headroom.

The step down to the 14-core Intel Core Ultra 5 225H keeps the same cores at lower clocks and graphics for a lower price. A move to BGA 2114 Arrow Lake-HX is a different soldered platform with many more cores at 55 W for desktop replacements. That change means a whole new system.
