Intel Celeron 7305 socket: BGA 1744

What the Celeron 7305 is

The Intel Celeron 7305 is a 5-core, 5-thread member of the 12th Gen Core family for BGA 1744 systems from February 2022. One Performance-core without Hyper-Threading with four Efficient-cores give 5 cores and 5 threads, with clocks fixed at 1.10 GHz with no boost. The package carries 8 MB of Intel Smart Cache. Processor base power is 15 W with turbo up to 55 W.

The memory controller supports DDR5, DDR4 and low-power variants over two channels to 64 GB, specifically DDR5 up to 4800 MT/s, DDR4 up to 3200 MT/s, LPDDR5 up to 5200 MT/s and LPDDR4x up to 4267 MT/s, two channels, up to 64 GB. SODIMM boards allow later memory changes while soldered LPDDR designs trade that option for thinner bodies. PCIe arrives as Gen4 with up to 20 lanes for graphics and NVMe on typical boards. Intel UHD Graphics (48 execution units, up to 1.10 GHz) drives laptop displays with hardware video decode.

Entry laptops and school machines take this 5-core Celeron where steady pace beats peak bursts. Fixed clocks at 1.10 GHz with no boost keep behavior predictable in thin bodies with small cooling. Four Efficient-cores absorb background threads while the single Performance-core without Hyper-Threading handles the foreground task. The 9 W class such as Intel Core i5-12600H suits fanless tablets, while this 15 W part fits larger school laptops.

Socket and motherboard compatibility

The Celeron 7305 fits the BGA 1744 soldered package at 50 × 25 mm. The chip is soldered and cannot be replaced. Laptop makers solder it with cooling for the 15 W band, so configuration happens once at order time.

There is no socketed variant and no board choice beyond the system design. Memory type, display outputs and expansion follow the laptop design, not a retail motherboard list. The 9 W U parts live on BGA 1781 instead, so compare Intel Core i5-12600H when battery life matters most.

Memory, PCIe and cooling

DDR5 up to 4800 MT/s, DDR4 up to 3200 MT/s, LPDDR5 up to 5200 MT/s and LPDDR4x up to 4267 MT/s, two channels, up to 64 GB. Dual-channel fitting stays mandatory for graphics performance, with 2 x 8 GB a common pick for entry machines and 2 x 16 GB for creation and multitasking.

PCIe Gen4 lanes wire graphics and NVMe on typical boards, with up to 20 lanes in total for storage and board devices. Fast Gen4 SSDs saturate laptop storage duty.

Cooling follows the chassis across 15 W base to 55 W turbo with heat pipes sized for sustained 15 W. No boxed cooler exists. Long sessions settle at the sustained power the body can reject, so cooling reviews of the exact model matter for purchase decisions.

Upgrade paths

No CPU upgrade exists on soldered boards for thin laptops. The lineup moves from fewer cores through this 5-core part to flagships such as Intel Core i5-12600H, chosen at purchase with display and memory. Storage and SODIMM memory where fitted are the only later changes for owners who keep the chassis for years.

Beyond this generation the replacement is a whole laptop on newer platforms with faster memory. The LGA, PGA and BGA: CPU package types explained guide explains the soldered tradeoff behind mobile designs.
