Intel Core i5-480M

The Intel Core i5-480M is a mobile processor from the Arrandale family, built on Intel's 32 nm process. It is a dual-core part with four threads, positioned as an end-of-life product with a modest average benchmark score of 429. This places it in the 6th percentile of all CPUs tracked, indicating that it sits near the very bottom of the performance spectrum in the current database.

Benchmark Performance

The raw benchmark results for the i5-480M paint a picture of a chip that is functional for basic tasks but far from competitive by modern standards. In Cinebench R23, the processor scores 1123 points in the multi-core test and 158 points in the single-core test. The Cinebench R20 run shows a similar pattern, with 471 points multi-core and 66 points single-core. The Geekbench scores are lower still, at 700 for multi-core and 369 for single-core. These numbers, when viewed in isolation, suggest a processor that is about a sixth as fast as a typical modern desktop chip in multi-threaded work.

Comparing the i5-480M to its nearest rivals, the data shows a remarkably tight cluster of performance. The Intel Celeron J4025 has an average score of 426, which is 0.6% lower than the i5-480M's 429. The AMD A8-3500M matches that with a score of 426, also 0.6% behind. On the other side, the Intel Celeron 3865U scores 432, which is 0.8% higher, and the AMD Athlon II X3 415e scores 433, also 0.8% higher. These deltas are statistically insignificant; the i5-480M is effectively tied with all four of these processors in aggregate performance.

The percentile ranking of 6% underscores the reality of this processor's standing. It is not merely slower than the majority of CPUs; it is slower than roughly 94% of all processors in the database. The average benchmark score of 429 is the central reference point, and the nearest rivals all sit within a 1% band around it, meaning that any of these chips would deliver nearly identical real-world performance in most applications.

Power and Thermals

The i5-480M carries a thermal design power (TDP) of 35 watts. This is a modest figure that classifies the chip as a low-power mobile part, suitable for thin-and-light laptops from its era. The 35 W TDP means that a simple cooling solution, such as a small heatpipe and a low-profile fan, is sufficient to manage thermals under sustained load. This is in stark contrast to higher-end desktop parts that require large tower coolers or liquid cooling.

In terms of cooling tier, this processor can be adequately served by what is typically described as a capable air cooler, even a compact one. The 32 nm process node helps keep heat density manageable, and the 81 mm² die size with 382 million transistors is small enough that heat dissipation is not a challenge. The integrated graphics, noted as a chipset feature on certain motherboards, adds a minor amount of heat but does not change the overall cooling requirement.

For system integrators or users looking at this chip, the 35 W TDP implies that the thermal solution is not a limiting factor. Any standard laptop chassis from 2011 would have been designed to handle this heat output without issue. The absence of a high TDP also means that battery life was likely a priority, though the benchmark data does not quantify power consumption directly.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance is instructive for understanding how the i5-480M handles different workloads. In Cinebench R23, the single-core score is 158, while the multi-core score is 1123. The ratio between these is approximately 7.1, which is close to the ideal scaling for a dual-core processor with four threads. This indicates that the multi-threaded performance is scaling well given the hardware, but the absolute numbers are low.

In Geekbench, the single-core score is 369, and the multi-core score is 700, yielding a ratio of about 1.9. This lower scaling suggests that the Geekbench multi-core test may be less efficient at utilizing the four threads, or that the memory bandwidth of the DDR3 support is a bottleneck. The Cinebench tests, which are more compute-heavy, show better scaling.

What this means for real workloads is that the i5-480M will handle lightly threaded tasks, such as web browsing or office document editing, with a responsiveness that is acceptable for basic use, but it will struggle with any application that relies heavily on a single thread. The single-core scores of 158 (R23) and 369 (Geekbench) are roughly a quarter of what a modern budget processor achieves. Conversely, multi-threaded tasks, such as video encoding or 3D rendering, will see a benefit from the four threads, but the absolute performance is still very low, so these tasks will be slow.

How It Compares

Against the Intel Celeron J4025, the i5-480M holds a razor-thin lead of 0.6%. The J4025 is a newer, dual-core Celeron, but the benchmark data shows no meaningful advantage for either chip. In practical terms, a user would not notice any difference between the two in everyday tasks.

The Intel Celeron 3865U is a slightly faster competitor, with an average score of 432, which is 0.8% higher than the i5-480M. This delta is within the margin of error for benchmarking, so the two should be considered performance equivalents. The 3865U is a Kaby Lake part, but its low power design keeps it in the same performance class.

The AMD A8-3500M is the closest rival, matching the i5-480M with an average score of 426, a 0.6% difference. This is a quad-core Fusion part from AMD, but the data shows that the i5-480M's higher clock speeds on fewer cores result in a statistical tie.

The AMD Athlon II X3 415e is the fastest of the four rivals, scoring 433, which is 0.8% higher than the i5-480M. This triple-core desktop chip has a slight edge, but again, the difference is negligible. All five processors fall within a 2% performance band, making them interchangeable for most workloads.

Who Should Consider It

The i5-480M is a processor for legacy systems or very specific low-budget use cases. For gaming, the data is not favorable. The single-core performance, as measured by a Geekbench score of 369, is far below what modern games require for smooth frame rates. The integrated graphics, available only on certain motherboards as a chipset feature, would further limit gaming to very old or lightweight titles.

For content creation, the multi-core Cinebench R23 score of 1123 indicates that the i5-480M can complete rendering tasks, but very slowly. A user editing a simple video or rendering a basic 3D scene would see long wait times. This chip is not suited for professional creation workloads.

For office and productivity tasks, the i5-480M is serviceable. A Geekbench single-core score of 369 is enough for word processing, spreadsheet work, and web browsing with a few tabs open. The four threads help with multitasking, allowing a user to run an email client, a browser, and a document editor simultaneously without significant slowdown. However, the 6th percentile ranking means that even budget laptops from the last several years will outperform it. The intended audience is someone repairing an old laptop or building a minimal system for basic administrative work, where the 35 W TDP and low heat output are acceptable trade-offs for the low performance.
