AMD A10-5800K

The AMD A10-5800K is a desktop processor from the Piledriver architecture, built on a 32 nm process with four cores and four threads. It operates at a base clock of 3.80 GHz and a boost clock of 4.20 GHz, and it integrates Radeon HD 7660D graphics. Benchmark results place this chip at the 20th percentile among all CPUs, with an average benchmark score of 778 across tested workloads.

Benchmark Performance

The A10-5800K’s average benchmark score of 778 places it in a tightly contested cluster of rivals. The data shows the nearest competitor, the Intel Core i5-3320M, also scores 779, yielding a delta of -0.1% against the A10-5800K — a statistically negligible difference. Similarly, the Intel Core i5-760 matches with 779 and a -0.2% delta, while the Intel Core i5-680 scores 777, just 0.1% behind. The AMD Athlon X4 760K, a sibling from the same socket generation, scores 777 with a 0.2% delta. In practical terms, the A10-5800K trades blows with these rivals within a margin of less than half a percent, meaning no meaningful performance separation exists in aggregate workloads.

However, the aggregate score hides a stark split. The Geekbench multicore score is 1102, while the single-core score is 454. This disparity is significant; the multicore result is roughly 2.4 times the single-core figure, indicating that the processor’s strength lies in parallel workloads rather than lightly threaded tasks. Against the nearest rivals, the multicore score of 1102 would position the A10-5800K well ahead of the Intel Core i5-3320M, which is a mobile part, but the deltaPct values in the FACT PACK are based on the average score, not the individual Geekbench runs. Since the average score is nearly identical to the i5-3320M, the multicore advantage is offset by a weaker single-core showing. For example, the single-core score of 454 is low for a desktop part, and this drags the average down relative to what the multicore score might suggest. The data indicates a processor that punches above its weight in multi-threaded scenarios but falls behind in single-thread responsiveness.

Single-Thread vs Multi-Thread Behavior

The Geekbench split — 1102 multicore versus 454 single-core — reveals a clear behavioral profile. The multicore score is more than double the single-core score, which is typical for a four-core, four-thread design without simultaneous multithreading. Real-world implications are straightforward: applications that can utilize all four cores see a substantial throughput boost, while single-threaded workloads leave much of the processor idle. The 3.80 GHz base clock and 4.20 GHz boost clock help mitigate the single-thread deficit, but the Piledriver architecture’s per-core efficiency trails its contemporaries. Compared to the Intel Core i5-680, which matches the A10-5800K’s average score of 777, the A10-5800K likely wins in multi-threaded rendering tasks but loses in single-threaded games or legacy software. The 0.1% delta between these two parts underscores that the overall performance is balanced, yet the composition of that performance is very different — the AMD chip relies on raw core count and clock speed, while the Intel chips typically have stronger individual cores. For mixed workloads, the benchmark results indicate that the A10-5800K will feel responsive in multi-tasking environments with several active threads, but it may stutter in single-threaded bottlenecks such as older game engines or spreadsheet recalculation. The lack of L3 cache (none listed) further emphasizes that this is a value-oriented design, relying on the 4 MB shared L2 cache and dual-channel memory bandwidth to feed its cores.

Power and Thermals

The A10-5800K carries a TDP of 100 watts, which places it in a moderate power class for a desktop processor of its era. This TDP figure implies that a capable air cooler is sufficient for stock operation, given that the boost clock of 4.20 GHz is only 0.40 GHz above the base clock — a modest headroom that does not demand exotic cooling solutions. The 32 nm process node from GlobalFoundries, with 1,303 million transistors on a 246 mm² die, suggests a relatively dense chip for its time, but the 100 W TDP indicates that power density is manageable. In comparison to the nearest rivals, the Intel Core i5-3320M is a mobile part with a much lower TDP, but the FACT PACK does not list that value, so it cannot be cited. What the data does show is that the A10-5800K’s 100 W TDP is a full desktop-class rating, meaning it requires a standard desktop cooling solution rather than a low-profile or passive cooler. The integrated Radeon HD 7660D graphics share the same thermal envelope, so the CPU and GPU together are accounted for within that 100 W figure. Users should expect the processor to run warm under sustained multi-threaded loads, but not to the point of throttling with a stock cooler. The multiplier is unlocked, which allows overclocking, but pushing beyond the 4.20 GHz boost clock would increase heat output beyond the 100 W TDP, necessitating a more robust cooling solution — though no specific cooler size or wattage is provided in the FACT PACK to quantify that requirement.

Platform and Compatibility

The A10-5800K uses the AMD Socket FM2, which is a dedicated desktop platform for the Trinity generation of Piledriver processors. Memory support is limited to DDR3, running in dual-channel mode with a maximum bandwidth of 29.9 GB/s. This memory bandwidth figure is modest by modern standards but was adequate for the integrated Radeon HD 7660D graphics, which share system memory. ECC memory is not supported, confirming this is aimed at consumer desktops rather than workstations. PCIe connectivity is Gen 2, which is a generation behind the PCIe Gen 3 that was becoming common at the time of release, but the FACT PACK does not list lane counts or configuration, so no further specifics can be given. The processor was released on 2012-10-01 and is now end-of-life, meaning it is no longer in active production. The upgrade path is limited to other FM2 processors from the same Trinity or later Richland generation, but the FACT PACK does not list those alternatives. For a user on this platform, the A10-5800K sits near the top of its socket’s performance range, given that the Athlon X4 760K — a close rival at 777 average score — is also FM2-compatible and performs nearly identically. The unlocked multiplier is a notable feature, allowing users to overclock the CPU without changing the base clock, which simplifies tuning on FM2 motherboards. The integrated graphics mean no discrete GPU is required for basic display output, but the 29.9 GB/s memory bandwidth will limit graphics performance in memory-intensive scenarios. Overall, the platform is a self-contained ecosystem for budget-oriented builds circa 2012, with no support for newer memory standards or PCIe Gen 3 peripherals.

Who Should Consider It

The benchmark data paints a clear picture of the A10-5800K’s target audience. For gaming, the integrated Radeon HD 7660D provides a baseline experience, but the single-core score of 454 suggests that CPU-bound titles from the 2012 era would run adequately at low to medium settings — though no specific frame rates are available in the FACT PACK. The multicore score of 1102 is more encouraging for content creation tasks like video encoding or 3D rendering, where all four cores can be utilized. The 20th percentile ranking among all CPUs indicates that this is a below-average performer in the grand scheme of desktop processors, so it is not suited for high-end workloads. However, the near-identical average score to the Intel Core i5-760 (779, -0.2% delta) and Intel Core i5-680 (777, 0.1% delta) means that for everyday productivity — web browsing, office applications, light photo editing — the A10-5800K is on par with those older Intel quad-core parts. The lack of ECC memory and DDR3-only support rules out server or error-sensitive workstation use. The unlocked multiplier appeals to enthusiasts who want to squeeze extra performance, but the 100 W TDP limits headroom without better cooling. In summary, the A10-5800K is best suited for budget desktop builds where integrated graphics are a necessity, multi-threaded batch tasks are common, and the user is comfortable with a platform that has no forward upgrade path. Those who primarily run single-threaded applications would be better served by the Intel rivals, which match the average score but likely offer superior per-core performance, based on the single-core versus multicore split. For users with an existing FM2 motherboard, the A10-5800K is a solid drop-in upgrade over lower-tier Trinity parts, but for new builds, the data suggests looking elsewhere given the end-of-life status and PCIe Gen 2 limitation.
