AMD A10-5800B vs AMD A10-6800K Comparison

Where Each One Wins

The recorded benchmarks give a clear, though narrow, advantage to the AMD A10-6800K across both measured tests. The A10-6800K wins the multi-core test with a score of 1140 against the A10-5800B's 1128, a delta of 1.1%. In single-core performance, the gap widens slightly: the A10-6800K scores 478 versus 459 for the A10-5800B, a 4.1% lead. That single-core margin is the more meaningful separation, as it reflects the higher clock speeds of the Richland part.

The A10-5800B does not win any of the head-to-head benchmarks. Its average benchmark score sits at 794, while the A10-6800K averages 809. In percentile terms, the A10-6800K lands at the 22nd percentile of all CPUs in the database, while the A10-5800B sits at the 21st percentile. The practical difference is small enough that most workloads would show only minor frame-rate or render-time changes, but the data consistently favors the A10-6800K.

For use-case splitting, the A10-6800K is the better pick for lightly threaded applications, given its 4.1% single-core advantage. Multi-threaded tasks still favor the A10-6800K, but the 1.1% delta is nearly negligible. The A10-5800B remains competitive for general desktop use where the extra 100 MHz base clock of the A10-6800K does not translate into perceptible gains. Both processors are quad-core, quad-thread parts, so neither will excel in heavily parallel workloads compared to modern CPUs, but within this pair, the A10-6800K holds every measured edge.

Architecture Differences

Both processors are built on the Piledriver architecture and manufactured on a 32 nm process at GlobalFoundries. They share the same transistor count of 1,303 million and the same die size of 246 mm². The socket is identical, AMD Socket FM2, and both use DDR3 memory in a dual-channel configuration. The A10-6800K comes from the Richland generation, while the A10-5800B is from the earlier Trinity generation. That generation shift explains the clock speed differences and the integrated graphics upgrade.

The A10-6800K has a base clock of 4.10 GHz and a boost clock of 4.40 GHz. The A10-5800B runs at 3.80 GHz base and 4.20 GHz boost. The 300 MHz base and 200 MHz boost deltas are the primary architectural differentiators beyond the graphics unit. The A10-6800K integrates a Radeon HD 8670D, while the A10-5800B integrates a Radeon HD 7660D. The memory bandwidth also differs: the A10-6800K measures 34.1 GB/s, versus 29.9 GB/s for the A10-5800B. That bandwidth increase likely benefits the integrated graphics and any memory-sensitive workloads.

The cache layout is nearly identical: both have 192 KB of L1 cache and 4 MB of L2 cache. The A10-5800B lists its L2 as "4 MB (shared)", while the A10-6800K lists "4 MB" without the shared qualifier, but functionally the capacity is the same. Neither processor has L3 cache. The A10-6800K has an unlocked multiplier, making it suitable for overclocking, while the A10-5800B does not. Both support PCIe Gen 2 and do not support ECC memory. The production status for both is end-of-life.

Specification Differences

The two processors differ in several measurable fields. The base clock is 4.10 GHz for the A10-6800K versus 3.80 GHz for the A10-5800B. The boost clock is 4.40 GHz versus 4.20 GHz. The integrated graphics differ: Radeon HD 8670D on the A10-6800K, Radeon HD 7660D on the A10-5800B. Memory bandwidth is 34.1 GB/s versus 29.9 GB/s. The A10-6800K has an unlocked multiplier; the A10-5800B does not. The codename differs: Richland for the A10-6800K, Trinity for the A10-5800B. The release date is later for the A10-6800K, 2013-05-31 versus 2012-10-01. The launch MSRP for the A10-6800K was $142; the A10-5800B has no recorded launch MSRP.

The part numbers also differ: AD680KWOHLBOXAD680KWOA44HL for the A10-6800K and AD580BWOA44HJ for the A10-5800B. The L2 cache is listed as "4 MB" for the A10-6800K and "4 MB (shared)" for the A10-5800B, though the capacity is identical. Everything else, including socket, process node, transistor count, die size, L1 cache, memory type, memory bus, PCIe generation, ECC support, TDP, and production status, is the same.

Head-to-Head Benchmarks

The multi-core Geekbench test shows the A10-6800K scoring 1140 against the A10-5800B's 1128. That is a 1.1% delta, which is within run-to-run variance for most benchmark suites. The single-core test shows a larger spread: 478 for the A10-6800K versus 459 for the A10-5800B, a 4.1% advantage. These are the only two benchmark results recorded for this pair, and the A10-6800K wins both.

The average benchmark scores reinforce the pattern. The A10-6800K averages 809 across its recorded benchmarks, while the A10-5800B averages 794. That 15-point gap is modest but consistent. In the nearest rivals table, the A10-6800K's average score of 809 places it alongside the Intel Core i7-870S (809, 0% delta) and the AMD Athlon X4 850 (806, 0.4% delta). The A10-5800B's average of 794 sits near the AMD A6-9400 (794, -0.1% delta) and the AMD A10-7850K (796, -0.3% delta). The A10-6800K also edges out the Intel Xeon X5482 (805, 0.4% delta) and trails the Intel Core i7-5550U (813, -0.5% delta). The A10-5800B comes close to the AMD Ryzen Embedded R1606G (797, -0.3% delta) and leads the Intel Core 2 Extreme QX9770 (790, 0.5% delta).

The single-core gap of 4.1% is the most actionable number from the head-to-head data. For applications that rely on a single thread, such as older games or lightly threaded productivity tools, the A10-6800K will show a noticeable improvement. The multi-core delta of 1.1% suggests that both processors are effectively equivalent for fully threaded workloads, which makes sense given their identical core and thread counts.

The Verdict

The data points to the AMD A10-6800K as the stronger processor in every measured category. It wins both head-to-head benchmarks, has a higher average score (809 versus 794), and reaches a higher percentile rank (22 versus 21). The single-core advantage of 4.1% is the most compelling reason to choose it, especially for users who run applications that do not scale well across multiple cores. The higher base and boost clocks, 4.10 GHz and 4.40 GHz respectively, directly contribute to that lead.

The A10-5800B is not without merit. Its 3.80 GHz base and 4.20 GHz boost clocks are still respectable for its generation, and its average score of 794 places it within 1.9% of the A10-6800K's average. For users who already own a Trinity-based FM2 motherboard, the A10-5800B remains a functional quad-core option. However, the A10-6800K offers a better integrated GPU (Radeon HD 8670D versus Radeon HD 7660D), higher memory bandwidth (34.1 GB/s versus 29.9 GB/s), and an unlocked multiplier for overclocking. Those features make it the more flexible choice.

The A10-6800K's release on 2013-05-31 came roughly eight months after the A10-5800B's 2012-10-01 launch, and the later part benefits from the Richland generation refinements. The launch MSRP of $142 for the A10-6800K is recorded, while the A10-5800B has no such figure, but pricing should not factor into the analysis beyond that single recorded value. The verdict is straightforward: the A10-6800K is the superior part across the measured benchmarks, with the single-core test providing the clearest separation. The A10-5800B is a capable fallback for Trinity-era systems, but it does not outperform the A10-6800K anywhere in the recorded data.
