AMD A4-5300B

The AMD A4-5300B is a desktop APU from the Trinity generation, built on Piledriver architecture at GlobalFoundries' 32 nm process. It has 2 cores and 2 threads, with a base clock of 3.40 GHz and a boost clock of 3.60 GHz. Integrated graphics are provided by a Radeon HD 7480D, and the memory controller supports dual-channel DDR3 with 25.6 GB/s of bandwidth. The CPU uses AMD Socket FM2 and carries a 65 W TDP. Its average benchmark score is 449, which places it at the 7th percentile of all CPUs in the database; Geekbench results are 515 in multicore and 383 in single-core. The production status is end-of-life, and the part was released on 2012-10-01.

How It Compares

Against the AMD A10-5745M, the A4-5300B records a delta of 0.1%, and both parts show an average score of 449. The two chips are effectively tied in aggregate benchmark performance. Although the A10-5745M is a different model, the score delta is small enough that applications would not consistently separate them.

Against the Intel Celeron G1620T, the A4-5300B is 0.3% ahead; the Celeron averages 448. This is also a minor margin. In the database's average-score ledger, the A4-5300B and the Celeron G1620T occupy essentially the same performance tier.

Against the Intel Core i3-540, the A4-5300B trails by 0.4%; the Core i3-540 averages 451. This is the only near rival in the group that holds a lead over the A4-5300B. The gap is still tiny, but it is the largest negative delta among the four comparisons.

Against the AMD A6-5400K, the A4-5300B is 0.4% ahead; the A6 averages 447. This is the largest positive delta in the set, yet it remains within the same narrow band. The four nearest rivals span average scores from 447 to 451, with deltas ranging from -0.4% to 0.4% relative to the A4-5300B.

Power and Thermals

The A4-5300B is rated at a 65 W TDP. This places it in the mainstream desktop power class. The die is 246 mm² and contains 1,303 million transistors, built on a 32 nm process at GlobalFoundries. A 65 W envelope implies a conventional entry-level air cooler is sufficient; no liquid cooling or high-end tower cooler is required. The integrated Radeon HD 7480D is part of the same silicon, so the thermal solution must cover both the CPU cores and the integrated graphics engines. The multiplier is locked, meaning the processor does not support multiplier-based overclocking. The absence of an unlocked multiplier limits enthusiast tuning options and keeps the thermal requirement tied to the default 65 W specification.

Benchmark Performance

The Geekbench multicore score is 515, and the single-core score is 383. The average benchmark score of 449 is the figure used for ranking, and the 7th percentile placement shows that the A4-5300B occupies a low position in the overall CPU performance distribution. Against its nearest rivals, the A4-5300B leads the A6-5400K by 0.4%, leads the Celeron G1620T by 0.3%, is 0.1% ahead of the A10-5745M, and trails the Core i3-540 by 0.4%. These deltas are so small that the aggregate scores of all five parts are effectively interchangeable. The largest positive and negative deltas are both 0.4%, which is a very tight cluster.

The single-core score of 383 is the lower of the two Geekbench results, indicating limited per-thread throughput. The multicore score of 515 is higher, but with 2 cores and 2 threads, there is no extra thread count to hide memory or scheduling latency. The cache hierarchy consists of 96 KB of L1 cache and 1 MB of shared L2 cache, with no L3 cache present; this configuration is consistent with the processor's low percentile ranking. In practical terms, the data shows a processor that is competitive only with the few parts immediately surrounding it in the database.

Platform and Compatibility

The A4-5300B uses AMD Socket FM2. Memory support is dual-channel DDR3 with a peak bandwidth of 25.6 GB/s; ECC memory is not supported. PCIe connectivity is Gen 2, which is available for discrete expansion cards. The integrated Radeon HD 7480D enables display output without a separate graphics card. The production status is end-of-life, and the original release date was 2012-10-01. The multiplier is locked, and the part number is AD530BOKA23HJ. The processor has no L3 cache, so the 1 MB shared L2 cache is the only level of cache shared between the two cores. Because the socket is FM2 and the product is discontinued, any processor upgrade would need to come from the FM2-compatible family; the board's PCIe Gen 2 slots remain usable for add-in devices such as discrete graphics or storage controllers. The market segment is desktop, so it is designed for a traditional desktop motherboard rather than a mobile platform.

Who Should Consider It

Benchmark results indicate the A4-5300B is suited to basic desktop workloads that do not demand high multi-threaded throughput. Office productivity, web browsing, and similar light tasks fit the processor's profile, with 2 cores and 2 threads sufficient for such usage. The 515 Geekbench multicore score and 7th percentile placement show limited headroom for content creation workloads such as video encoding, rendering, or compilation, which typically scale with more threads. The integrated Radeon HD 7480D provides the graphics output path, but the listed benchmark scores contain no GPU performance measurement, so gaming suitability cannot be determined from this data set. The dual-channel DDR3 memory path with 25.6 GB/s bandwidth is a modest but adequate pipeline for office-level memory traffic. Users who need more compute performance should look toward processors higher in the percentile ranking; those who remain with the A4-5300B should plan for light, single-thread-focused applications. The platform's PCIe Gen 2 support and FM2 socket define the expansion and upgrade boundaries, and the end-of-life status means no new silicon revisions are expected from this part.
