Celeron 4305U Details

Ranking #1235 in single-core performance and #1440 in multicore scoring, the Intel Celeron 4305U presents a surprisingly balanced profile for a budget mobile processor. Launched in April 2019 as part of Intel's Whiskey Lake-U series, this dual-core CPU operates at a base frequency of 2.2 GHz with a locked multiplier and no support for simultaneous multithreading. Built on a 10 nm manufacturing process, the 4305U is packaged in a BGA 1528 form factor, designed for thin and light laptops, where its 15 W TDP ensures efficient power consumption. Despite its modest positioning, the processor delivers competitive single-threaded performance, placing it ahead of several older mainstream and enthusiast CPUs in the single-core rankings, such as the Core i7-950 and A10-6800K. However, its multicore score of 4405 reveals a more modest capability, trailing behind modern quad-core and higher-tier processors in the same price bracket.

The Celeron 4305U integrates Intel's UHD Graphics 620, a capable GPU for basic multimedia and light gaming, with a maximum frequency of 1.0 GHz and support for up to three display outputs. It supports DDR4 memory at a rated speed of 2133 MT/s via a dual-channel interface, offering a memory bandwidth of 34.1 GB/s. While the processor lacks ECC memory support and does not include AVX-512 instructions, it does support AVX2, BMI1, BMI2, FMA3, and CLMUL, enabling it to handle modern workloads efficiently within its constraints. Virtualization technologies such as VT-x and VT-d are present, making it suitable for basic virtual machine environments.

When compared to its contemporaries, the 4305U holds its own against other low-power Celerons and Pentiums, outperforming the Celeron J4125 and Pentium G3450T in both single and multicore benchmarks. However, it is clearly outpaced by more recent processors like the Core i5-4310U and the modern Ryzen 9 9950X3D, which dominate the top-tier rankings. In the overall performance landscape, the 4305U ranks #1286 out of 2060 processors, indicating its role as a value-oriented solution rather than a high-performance option. As of March 2026, the processor remains relevant for entry-level laptops and office workstations where power efficiency and integrated graphics are prioritized over raw processing power. Its legacy lies in offering a reliable, energy-efficient platform for everyday computing tasks.
