Intel Celeron 4305UE

The Intel Celeron 4305UE is a dual-core mobile processor built on Intel’s Whiskey Lake architecture, targeting entry-level laptops and embedded systems. With a 15W TDP and a 2.00 GHz base clock, this chip is designed for efficiency rather than raw performance. Benchmark data places it in the 14th percentile of all CPUs tested, indicating that it trails the vast majority of modern processors. Its average benchmark score of 605 puts it in a tightly contested cluster where a single point separates it from several older or lower-power rivals.

How It Compares

The Intel Core i7-610E is the closest rival, with an average score of 606 against the Celeron 4305UE’s 605. The delta is a negligible -0.1%, meaning the two processors perform statistically identically in aggregate workloads. This is notable because the i7-610E is a much older part, yet the Celeron’s modern architecture does not translate into a measurable advantage in the compiled benchmark suite.

The Intel Atom x7-E3950 also posts a 606 average score, again showing a -0.1% delta. This comparison is particularly telling: the Atom is a quad-core Silvermont-based chip designed for fanless tablets and low-cost devices, yet it matches the Celeron 4305UE in overall benchmark output. The data suggests that the Celeron’s higher clock speed and newer core design do not overcome the Atom’s additional cores in multi-threaded scenarios.

The Intel Core i5-2430M, a Sandy Bridge dual-core from 2011, likewise scores 606, yielding a -0.1% delta. This is a stark illustration of how little performance has improved in the entry-level mobile segment over a decade. The i5-2430M has a similar core and thread count but a much higher turbo clock, yet the Celeron 4305UE holds its ground purely on architectural efficiency.

The AMD Phenom II X4 830, a quad-core desktop processor from the K10 era, also lands at 606 with a -0.1% delta. This is the most surprising result: a modern 10nm dual-core chip matches a four-core desktop part from a decade ago. The Celeron’s memory bandwidth of 34.1 GB/s and dual-channel DDR4 support likely compensate for its core deficit, though neither chip emerges as a clear winner.

Power and Thermals

The Celeron 4305UE carries a 15W TDP, placing it firmly in the low-power mobile segment. This thermal envelope is typical for ultraportable laptops and fanless industrial designs, where heat dissipation is constrained. The chip uses a 10nm process node from Intel’s Whiskey Lake generation, which contributes to its efficiency but does not grant it any performance headroom beyond its modest specifications.

Given the 15W TDP, the processor can be adequately cooled by a simple passive heatsink or a low-profile active cooler. No discrete graphics solution is required, as the integrated UHD Graphics 610 handles display output. The lack of a boost clock means the chip operates at a constant 2.00 GHz, which simplifies thermal management — there are no transient power spikes to accommodate. This makes the 4305UE suitable for thin-and-light chassis where sustained load is rare and burst performance is not a priority.

Benchmark Performance

In Cinebench R15 multi-core, the Celeron 4305UE scores 145. This is a low figure, consistent with its dual-core, dual-thread configuration. The score indicates that the chip is suitable for basic productivity tasks like document editing or web browsing, but it will struggle with rendering or video encoding.

Cinebench R20 multi-core yields 606, which exactly matches the average score of its nearest rivals. The single-core score of 85 in the same test is more revealing: it reflects the 2.00 GHz base clock with no turbo boost, limiting per-thread performance. In contrast, the R20 single-core score of 85 is lower than many older dual-core parts that had higher clock speeds or turbo capabilities.

Cinebench R23 multi-core shows 1444, while the single-core score is 203. The multi-core result is roughly seven times the single-core score, which is expected for a dual-core chip with no SMT. This ratio suggests that scaling to both cores is efficient, but the absolute numbers remain low. Geekbench results reinforce this: multi-core 1086 and single-core 668, both figures placing the chip in the lower quartile of modern processors.

Relative to its rivals, the Celeron 4305UE is never more than 0.1% behind or ahead in average score. This means that in aggregate, it is interchangeable with the i7-610E, Atom x7-E3950, i5-2430M, and Phenom II X4 830. The differences are within measurement noise, so the data cannot distinguish between these five processors based on overall performance alone.

Single-Thread vs Multi-Thread Behavior

The Celeron 4305UE shows a pronounced gap between its single-thread and multi-thread scores. In Cinebench R23, the multi-core score of 1444 is 7.1 times the single-core score of 203. For a dual-core chip without hyper-threading, the theoretical maximum scaling is 2x, so achieving 7.1x suggests that the multi-core test benefits from the low base clock in single-thread mode — the single-core result is disproportionately low, making the multiplier appear large. In reality, the absolute multi-core performance is modest.

In Geekbench, the multi-core score of 1086 is 1.6 times the single-core score of 668. This is closer to the expected 2x scaling for two cores, indicating that the Geekbench workload is less sensitive to clock speed and better utilizes both cores. The discrepancy between the R23 and Geekbench scaling ratios suggests that Cinebench is more heavily dependent on per-core frequency, which is limited here to 2.00 GHz with no boost.

For real-world workloads, this split means that the Celeron 4305UE will handle multi-threaded tasks like video playback or background updates reasonably well, but single-threaded tasks such as spreadsheet calculations or JavaScript-heavy web pages will feel sluggish. The lack of a boost clock is the primary constraint: every workload runs at the same 2.00 GHz, so there is no headroom for bursty single-thread activity. The processor’s 14th percentile ranking underscores that it is best suited for basic, low-intensity use cases where consistent low power draw is more important than responsiveness.
