AMD A4-3330MX

The AMD A4-3330MX is a dual-core mobile processor from the K10 architecture family, built on the 32 nm process node under the Llano codename. It operates with a base clock of 2.20 GHz and a boost clock of 2.60 GHz, featuring 2 threads total and a TDP of 45 watts. Benchmark data places this chip at the 2nd percentile among all CPUs, with an average benchmark score of 345 across the two Geekbench tests recorded. This analysis walks through how that score translates into real-world positioning, thermal requirements, platform constraints, and workload suitability.

How It Compares

The nearest rival by average score is the Intel Pentium E5800, which also scores 345. The delta between the A4-3330MX and the Pentium E5800 is -0.1%, meaning the two are effectively tied in aggregate benchmark performance. This is notable because the Pentium E5800 is a desktop-oriented chip, while the A4-3330MX is designed for mobile systems, yet their overall compute output lands within a rounding error of each other.

The Intel Pentium E6600 matches the same average score of 345, again with a delta of -0.1%. This puts the A4-3330MX on par with another older dual-core desktop part. The data shows no meaningful performance gap between these two processors in the aggregate benchmark metric, suggesting that the A4-3330MX can hold its own against that generation of Pentium-class silicon despite its mobile focus.

The Intel Celeron 3755U also scores 345, with a delta of -0.1%. This is a more modern low-power mobile chip, and the fact that the A4-3330MX matches its average score indicates that the older Llano architecture still delivers comparable overall throughput in this specific benchmark. The near-zero delta suggests that generational improvements in efficiency did not translate into a large aggregate performance advantage for the Celeron.

The only rival with a positive delta is the Intel Pentium E6500, which scores 343. The A4-3330MX leads by 0.5% over this part. While that margin is small, it means the AMD chip edges out the Pentium E6500 in the average benchmark score. The data positions the A4-3330MX as essentially equivalent to its three closest rivals, with a slight but measurable lead over the fourth.

Power and Thermals

The A4-3330MX carries a TDP of 45 watts. For a mobile processor, this is a moderate power envelope that implies a cooling solution beyond a passive heatsink but not an aggressive high-performance cooler. In the context of the Llano generation, this TDP class is typical for mainstream laptops where the integrated graphics and CPU share the same thermal budget.

A 45-watt TDP means the processor can sustain its boost clock of 2.60 GHz under load without requiring exotic cooling. Standard laptop cooling designs—such as a single heat pipe with a small fan—are generally sufficient for this class of chip. The data does not include any thermal throttling metrics, but the TDP figure alone suggests that the A4-3330MX is suited for portable systems where the chassis can dissipate moderate heat.

Compared to lower-TDP mobile chips like the Celeron 3755U, the A4-3330MX draws more power, which could lead to shorter battery life under sustained load. However, the benchmark scores show that this additional power does not yield a performance advantage over that rival. The thermal implications are straightforward: the 45-watt envelope requires active cooling, and the chip is not designed for fanless or ultra-thin implementations.

Platform and Compatibility

The A4-3330MX uses the AMD Socket FS1, a socket designed for mobile Llano processors. This socket is specific to laptops and not compatible with desktop AM3+ or FM1 platforms. The integrated graphics are the Radeon HD 6480G, which means the chip includes a GPU on the same package, reducing the need for a discrete graphics card in basic systems.

Memory support is limited to DDR3, with a dual-channel memory bus. The data does not specify a memory bandwidth figure, but dual-channel DDR3 was standard for the era. ECC memory is not supported, which aligns with the mobile consumer market segment. The chip does not list PCIe support in the fact pack, so no conclusions can be drawn about expansion slot capabilities.

The production status is end-of-life, and the release date is December 19, 2011. As a result, the upgrade path is restricted to other Socket FS1 processors from the Llano line, all of which are now obsolete. The part number AM3330HLX23GX identifies this specific SKU, but with no launch MSRP provided, pricing information is unavailable. The multiplier is locked, so overclocking is not an option for users seeking additional performance.

Who Should Consider It

Given the benchmark scores, the A4-3330MX is best suited for basic office tasks, web browsing, and light document processing. The single-core score of 258 and multi-core score of 432 in Geekbench indicate that this chip handles everyday workloads without significant lag, but it is not designed for demanding applications. Users running spreadsheets, email clients, or video playback would find this processor adequate.

For gaming, the Radeon HD 6480G integrated graphics can handle older or less demanding titles at low settings, but the CPU scores suggest that modern games would struggle. The multi-core score of 432 places it far below current entry-level processors, so any workload relying on multiple threads—such as video encoding or 3D rendering—would be slow. Creation-oriented tasks are not recommended for this chip.

The 2nd percentile ranking among all CPUs means the A4-3330MX is at the very low end of the performance spectrum. It is a candidate for budget laptops where the primary use case is web access and productivity, not for users who need to run parallel compute tasks. The near-tie with the Intel Pentium E5800 and E6600 shows that it competes with early-2010s desktop dual-cores, so expectations should be set accordingly.

Benchmark Performance

The Geekbench multi-core score for the A4-3330MX is 432, while the single-core score is 258. The average benchmark score of 345 is derived from these two results. Against the Intel Pentium E5800, which also averages 345, the delta is -0.1%, meaning the A4-3330MX is essentially identical in aggregate performance. The multi-core score of 432 is the primary driver here, as the single-core score of 258 is notably lower.

The Intel Pentium E6600 also averages 345 with a delta of -0.1%, reinforcing the pattern that this AMD chip sits alongside those Pentium parts. The Celeron 3755U, a much newer architecture, also matches with a 345 average and -0.1% delta. This is surprising because the Celeron 3755U is built on a more modern process, but the Geekbench results show no aggregate advantage for the newer chip.

The only rival where the A4-3330MX leads is the Intel Pentium E6500, which averages 343. The delta of 0.5% means the AMD chip is ahead by roughly 2 points in the average score. While this is a small margin, it is consistent across the benchmark data. The multi-core score of 432 for the A4-3330MX suggests that in threaded workloads, it slightly outperforms the Pentium E6500, which likely has a lower multi-core result.

Single-Thread vs Multi-Thread Behavior

The single-core score of 258 is substantially lower than the multi-core score of 432, which is expected for a dual-core chip with no SMT. The ratio of multi-core to single-core is approximately 1.67, indicating that scaling across two cores is not perfectly linear—a typical result for the K10 architecture under Geekbench. This means that single-threaded applications will see weaker performance relative to multi-threaded ones.

The single-core score of 258 places the A4-3330MX below many contemporary low-end chips in tasks that rely on a single thread, such as web browsing JavaScript execution or spreadsheet recalculation. The multi-core score of 432, while still low in absolute terms, shows that the chip can leverage both cores for parallel workloads like compression or batch photo processing, albeit slowly.

The near-zero deltas against rivals in average score mask a potential split: the A4-3330MX’s multi-core performance may be closer to its rivals, but its single-core performance likely lags due to the older K10 architecture’s lower IPC. The data does not provide rival single-core scores, so a direct comparison is not possible, but the 258 single-core figure is a clear indicator that latency-sensitive work will not be this chip’s strength. Users prioritizing single-thread speed would find the A4-3330MX lacking, while those with moderately parallel workloads would see better relative performance.
