AMD A10-7860K

The AMD A10-7860K is a 4-core, 4-thread desktop processor built on the 28 nm Steamroller architecture (Godaveri codename) for the AMD Socket FM2+ platform. It operates at a base clock of 3.60 GHz with a boost clock of 4.00 GHz, features a Radeon R7 integrated GPU, and supports dual-channel DDR3 memory. With an average benchmark score of 904, it sits at the 23rd percentile of all CPUs, placing it firmly in entry-level territory for modern workloads. The data shows a part that trades heavily on its integrated graphics and unlocked multiplier rather than raw computational muscle.

How It Compares

The closest rival in the database is the Intel Core i5-5350U, which matches the A10-7860K exactly with an average score of 904 and a delta of 0%. This parity is notable because the i5-5350U is a low-power mobile part, whereas the A10-7860K is a desktop chip with a 65W TDP. Benchmark results indicate that the A10-7860K offers no performance advantage over this ultrabook-class Intel processor, meaning its desktop power envelope does not translate into superior throughput in synthetic averages.

The Intel Pentium Gold G6405T posts an average score of 905, just 0.1% ahead of the A10-7860K. This is a statistically insignificant margin, effectively placing the two processors in the same performance tier. The Pentium Gold achieves this with fewer cores and threads, suggesting that the A10-7860K’s four Steamroller cores are less efficient per thread than Intel’s modern dual-core designs. For users comparing raw multi-threaded capability, the difference is negligible in practice.

The Intel Core i5-4258U scores 906, a 0.2% edge over the A10-7860K. Like the i5-5350U, this is a dual-core mobile processor with Hyper-Threading, yet it still edges out the AMD part in average score. The data shows a pattern: the A10-7860K competes with, but does not beat, low-power Intel parts from several generations ago. This positions it as a legacy entry-point processor rather than a competitive modern option.

The Intel Xeon W3540, a much older quad-core workstation chip, averages 909, which is 0.6% higher than the A10-7860K. The Xeon W3540 features four cores and four threads at a much higher TDP, yet it still outperforms the A10-7860K in this aggregate metric. This suggests that the A10-7860K’s architectural efficiency is not sufficient to overcome its modest clock speeds, even against a decade-old server part.

Power and Thermals

The A10-7860K carries a TDP of 65W, which is a moderate figure for a desktop processor with integrated graphics. This TDP class implies that a stock cooler is sufficient for standard operation, though the unlocked multiplier invites overclocking that would push thermals upward. The 28 nm process node from GlobalFoundries is an older manufacturing technology, which typically results in lower power efficiency per transistor compared to more modern nodes. A capable air cooler should handle this chip comfortably at stock settings, but enthusiasts planning to use the unlocked multiplier should consider a larger aftermarket solution. The 65W rating also means system integrators do not need oversized power delivery components, keeping the platform relatively simple to build around.

Single-Thread vs Multi-Thread Behavior

Benchmark results show a pronounced weakness in single-thread performance. In Cinebench R23, the A10-7860K scores 392 points in single-core and 2778 points in multi-core, yielding a multi-to-single ratio of roughly 7.1x for four cores. This scaling is better than the theoretical 4x linear improvement because the single-core score is so low, but it indicates that the Steamroller architecture struggles with lightly threaded workloads. The Geekbench results reinforce this: 447 single-core and 1103 multi-core, a ratio of 2.5x, which is far below ideal scaling and suggests heavy contention or frequency limitations under full load.

The single-thread scores are among the lowest in the database, putting the A10-7860K in the bottom percentile for tasks like web browsing, spreadsheet interaction, or legacy software that relies on one strong core. Multi-threaded performance is comparatively better, with Cinebench R20 showing 1166 multi-core versus 164 single-core, a 7.1x ratio again. This pattern indicates that the processor is more suitable for batch workloads that use all four cores, such as video transcoding or rendering, rather than responsive everyday tasks. The 4 MB L2 cache is shared across the modules, which can help mitigate some multi-threaded latency, but the lack of L3 cache is a notable disadvantage for data-heavy applications.

FAQ

Q: How does the A10-7860K compare to the Intel Core i5-5350U?

A: The two processors have identical average scores of 904, with a delta of 0%. They are statistically tied in aggregate benchmark performance.

Q: What is the single-core performance in Cinebench R23?

A: The A10-7860K scores 392 points in Cinebench R23 single-core, which is a very low result indicative of weak per-thread execution.

Q: Does the A10-7860K support ECC memory?

A: No, ECC memory is not supported. The processor uses dual-channel DDR3 memory with a bandwidth of 34.1 GB/s.

Q: Is the multiplier unlocked?

A: Yes, the multiplier is unlocked, allowing for overclocking on compatible FM2+ motherboards.

Q: What is the production status of this processor?

A: The production status is end-of-life, meaning it is no longer manufactured as a current product.

Q: How many PCIe lanes does the CPU provide?

A: The CPU provides 16 PCIe Gen 3 lanes, which are available for discrete graphics or other expansion cards.

Who Should Consider It

The A10-7860K is suited for users who prioritize integrated graphics capability without a discrete GPU. The Radeon R7 IGP is a strong feature for entry-level gaming at low resolutions and settings, though the CPU’s 23rd percentile ranking means modern titles will be limited by both the GPU and the processor. For legacy gaming or eSports titles that are not heavily threaded, the 4.00 GHz boost clock helps, but the low single-core scores will cap performance in physics-heavy scenes.

Content creation workloads that are parallelized, such as video encoding or batch image processing, can take advantage of the four cores. The Cinebench R20 multi-core score of 1166 and R23 score of 2778 show that the processor can complete rendering tasks, but slowly. Users coming from a dual-core Pentium or Celeron might find the A10-7860K acceptable for occasional rendering, but the low percentile ranking means it is not a primary tool for professional creators. Office productivity software that uses multiple threads, such as spreadsheet recalculations or database queries, will see moderate benefit, but single-threaded responsiveness will feel dated.

The A10-7860K is best considered by builders who have an existing FM2+ motherboard and want a low-cost upgrade with integrated graphics. With a 65W TDP, it fits into modest systems without requiring a high-end cooler or power supply. The unlocked multiplier provides some headroom for users willing to overclock to recoup performance, though the 28 nm process limits gains. For anyone starting a new build, the data shows that rival Intel parts at similar scores offer better efficiency, but the A10-7860K remains a valid option for a specific niche: a compact, all-in-one CPU with graphics that can handle light gaming and multi-threaded batch tasks without a discrete card.
