AMD A10-4655M

The AMD A10-4655M is a 4-core, 4-thread mobile processor from the Piledriver architecture, built on a 32 nm process at GlobalFoundries. It operates with a base clock of 2.00 GHz and a boost clock of 2.80 GHz, within a 25 W TDP envelope. Benchmark data places this chip at the 6th percentile of all CPUs, with an average benchmark score of 434, indicating a position firmly in the entry-level segment of the mobile market.

Benchmark Performance

The A10-4655M delivers a Geekbench multi-core score of 590 and a single-core score of 278. These scores, when weighted into the average benchmark score of 434, show a processor that is competitive with a narrow cluster of low-power and older desktop parts. The data shows the A10-4655M is effectively tied with the Intel Core i5-2467M, which posts an average score of 435; the A10-4655M trails by just 0.2%. This is a negligible difference, placing the two chips within the margin of error for typical benchmark variance.

Against the Intel Xeon E5504, the situation is identical in percentage terms: the A10-4655M is 0.2% behind that chip's average score of 435. This is notable because the Xeon E5504 is a server-class part, yet the mobile A10-4655M matches its aggregate performance. Moving to the AMD Athlon II X3 415e, the A10-4655M leads by 0.3%, with that rival posting a 433 average score. The final rival, the Intel Celeron 3865U, scores 432, and the A10-4655M is 0.4% ahead of it. In all four comparisons, the deltas are under half a percentage point, which means the A10-4655M sits in a performance band where architectural differences and workload characteristics matter more than raw aggregate scores.

The multi-core figure of 590 is more than double the single-core figure of 278, which is a typical ratio for a quad-core part with no simultaneous multithreading. However, the absolute values are low by modern standards. The 6th percentile ranking underscores that this processor will struggle with demanding multi-threaded applications, but for light, intermittent tasks, the scores are internally consistent.

Who Should Consider It

Based strictly on the benchmark results, the A10-4655M is suitable for users whose primary workloads are basic office productivity, web browsing, and document editing. The single-core score of 278 is low, which means that applications with a dominant main thread—such as spreadsheet recalculation or lightweight code compilation—will operate without noticeable lag only if the tasks are short and infrequent. The multi-core score of 590 suggests that the processor can handle a few simultaneous background tasks, like a music player alongside a web browser, without significant contention.

Gamers should not consider this processor for anything beyond very old or extremely lightweight titles, as the integrated Radeon HD 7620G graphics and the low CPU scores will bottleneck modern game engines. For content creation, the data is discouraging: video encoding and 3D rendering rely heavily on sustained multi-core throughput, and a score of 590 places the A10-4655M far below the thresholds where those workloads become practical. The processor is better suited to a secondary or backup laptop for email, calendar, and note-taking, where the 25 W TDP enables fanless or low-noise designs.

The nearest rivals all sit within a 0.4% performance band, which means that the A10-4655M offers no meaningful advantage over any of them. A user choosing between this chip and the Intel Core i5-2467M would see identical performance in everyday tasks, so the decision would hinge on other platform features rather than CPU speed. The presence of the Radeon HD 7620G does provide a built-in graphics solution, which is a consideration for systems without a discrete GPU.

Single-Thread vs Multi-Thread Behavior

The split between the single-core score of 278 and the multi-core score of 590 reveals a scaling efficiency of roughly 2.12x from one core to four cores. This is lower than the theoretical 4x maximum, indicating that the Piledriver architecture and the shared 4 MB L2 cache introduce some contention when all cores are active. The boost clock of 2.80 GHz applies to single-core scenarios, while all-core operation will likely settle at a lower frequency, though the FACT PACK does not provide all-core clock data.

For real-world workloads, the low single-core score is the more limiting factor. Many legacy applications, as well as the startup phase of most modern software, are single-threaded. A score of 278 means that even the boost clock of 2.80 GHz cannot compensate for the architectural efficiency of newer rivals. The multi-core score, while higher, still falls short of the Intel Xeon E5504's aggregate performance, which is a 2010-era server chip. This suggests that the A10-4655M's multi-threaded advantage is minimal, and users should not expect it to handle parallel workloads with any speed.

The 4 MB shared L2 cache is a positive factor for multi-threaded tasks, as all four cores can access the same data pool without duplicating entries. However, the lack of L3 cache means that memory latency is higher when data is not resident in L2, which can hurt performance in cache-unfriendly workloads. The dual-channel DDR3 memory bus, with a bandwidth of 21.3 GB/s, is adequate for this processor's needs but will not be a differentiating feature.

How It Compares

Intel Core i5-2467M: The A10-4655M trails this rival by 0.2% in average benchmark score. This is a statistical dead heat, and the two chips should be considered performance equals. The Core i5-2467M is a dual-core part with Hyper-Threading, while the A10-4655M uses four physical cores, but the aggregate output is identical.

Intel Xeon E5504: The A10-4655M is 0.2% behind this server processor. The Xeon E5504 is an older quad-core part without boost clocks, yet it still matches the mobile A10-4655M. This comparison highlights that the A10-4655M's performance is not competitive with even early-generation server silicon.

AMD Athlon II X3 415e: The A10-4655M leads this triple-core desktop chip by 0.3%. The Athlon II X3 415e is a 45 nm part, so the A10-4655M's 32 nm process and higher boost clock give it a slight edge. The margin is small enough that real-world differences will be imperceptible.

Intel Celeron 3865U: The A10-4655M is 0.4% ahead of this modern low-end mobile chip. The Celeron 3865U is a dual-core part with a lower TDP, so the A10-4655M's extra cores provide a narrow advantage in aggregate scores, though its single-core performance is likely weaker.

Platform and Compatibility

The A10-4655M uses the AMD Socket FP2, which is a mobile-only socket from the Trinity generation. It supports dual-channel DDR3 memory with a bandwidth of 21.3 GB/s, and ECC memory is not supported. The PCIe interface is Gen 2, which limits the bandwidth available for discrete graphics or NVMe storage, though the FACT PACK does not specify the number of lanes. The integrated Radeon HD 7620G is the sole graphics solution unless a discrete GPU is added, and the Gen 2 PCIe link will cap the performance of any modern discrete card.

The processor is not multiplier-unlocked, so overclocking is not possible on this part. The production status is end-of-life, meaning it is no longer manufactured, and the release date of May 2012 places it in the early Trinity era. The part number is AM4655SIE44HJ, and the die size is 246 mm² with 1,303 million transistors, which is large for a 25 W TDP part, explaining the modest clock speeds. The platform is limited to DDR3, and there is no upgrade path to newer memory standards without a motherboard change. For a user with a Socket FP2 laptop, the upgrade options are restricted to other Trinity or later Richland parts, but the FACT PACK provides no data on those processors' performance.
