AMD A6-6420K

The AMD A6-6420K is a desktop processor from AMD, grouped under the A6 (Richland) generation and built on the Piledriver architecture with the Richland codename. It uses Socket FM2, has 2 cores and 2 threads, and carries a 4.00 GHz base clock with a 4.20 GHz boost clock. The integrated graphics is a Radeon HD 8470D, the TDP is 65 W, memory support is dual-channel DDR3, and the PCIe interface is Gen 2. In the supplied database record, the benchmarks array is empty, the average benchmark score is 0, the percentile against all CPUs is 50, and the nearestRivals array is also empty.

Benchmark Performance

The data set lists no measured benchmark results for this CPU. The benchmarks field is empty, and the average benchmark score is 0. Therefore, there is no raw score or normalized score to compare with other parts. The only global comparison number is the percentile against all CPUs, which is 50. That indicates a middle placement in the database, but with no benchmark entries behind it, the percentile is a classification value rather than a tested result.

Because the nearestRivals array is empty, no deltaPct values are available. No percentage lead or deficit over any named competitor can be computed from this record. The configuration facts remain: 2 cores, 2 threads, a 4.00 GHz base clock, a 4.20 GHz boost clock, a 65 W TDP, and a 32 nm process. These specifications can inform expectations, but they are not benchmark outputs.

One structural point from the data: the boost clock of 4.20 is higher than the 4.00 base clock, so the processor has a listed clock range to work within. The 65 W TDP is the only power figure in the record. No performance-per-watt score is provided. Since there are no scores, the CPU cannot be ranked against a specific rival from this entry alone.

Single-Thread vs Multi-Thread Behavior

The core and thread counts are both 2. That means the processor provides 2 logical threads total, with a single thread exposed by each core. It does not add extra threads for a workload. For single-threaded work, the processor is available on one thread, and the boost clock is 4.20; for multi-threaded work, the total resource pool is 2 threads. This is the central split in the record.

The cache configuration matters here. The L1 cache is 96 KB, and the L2 cache is 1 MB shared. No L3 cache is listed. With no L3 in the data, the shared 1 MB L2 is the highest cache level. The memory bus is dual-channel DDR3 with 29.9 GB/s of bandwidth. Memory-heavy workloads will share that bandwidth across the 2 cores; the data does not include a measured limit, but the shared structure is explicit.

Clock behavior is another factor. The base clock is 4.00, and the boost clock is 4.20. A workload that uses single-threaded or 2-thread execution can potentially reach the boost clock, while a workload with more than 2 active threads will not receive additional logical processors because only 2 threads exist. The data does not state how long boost is maintained or how many cores can hold the boost clock simultaneously.

Benchmark results do not quantify single-thread or multi-thread performance in this record. The percentile of 50 is the only aggregate position. Without a single-core score or a multi-core score in the benchmarks array, the record cannot show how this architecture behaves relative to other CPUs in the database.

Who Should Consider It

The A6-6420K is marked as a desktop processor, so it belongs in a desktop context. The integrated Radeon HD 8470D means a discrete GPU is not necessary for basic display output. Memory support is DDR3 with a dual-channel bus, and the listed bandwidth is 29.9 GB/s. Socket FM2 is the platform. These facts describe a conventional desktop part with onboard graphics.

For gaming, the data offers no frame rates or gaming scores. What the record does contain is a 2-core/2-thread CPU and a Radeon HD 8470D integrated GPU. Any gaming judgment beyond those specifications would be outside the record. For creation workloads, the key facts are 2 threads, 1 MB shared L2, no L3 cache, and DDR3 bandwidth of 29.9 GB/s. This is a small thread pool, so highly parallel creation tasks have few resources to use.

For office and general use, the integrated graphics, dual-channel DDR3, 65 W TDP, and desktop market segment align with a modest desktop configuration. The multiplier is unlocked, so users who want to adjust clock multiplier settings can do so. The production status is end-of-life, so the data does not present this as a current-production part.

Anyone building for heavily threaded workloads should note the 2-thread limit and the lack of ECC support in the record. Anyone already on Socket FM2 and looking for an unlocked desktop part can use these specifications as a filtering description.

Platform and Compatibility

Socket FM2 is the physical platform. The processor is built by GlobalFoundries on a 32 nm process, with 1,303 million transistors on a 246 mm² die. The architecture is Piledriver, the codename is Richland, and the generation is listed as A6 (Richland). The TDP is 65 W.

Memory support is DDR3, with a dual-channel bus and a listed bandwidth of 29.9 GB/s. ECC memory is not supported. PCIe is Gen 2. The integrated GPU is Radeon HD 8470D. The cache configuration is 96 KB L1, 1 MB shared L2, and no L3 cache. The production status is end-of-life; the release date is not listed.

The multiplier is unlocked, so clock multiplier adjustment is possible. The record does not list any other Socket FM2 processors, so the upgrade path cannot be mapped from this data. The socket alone establishes compatibility with Socket FM2 boards, but the data does not include a list of compatible boards or memory capacities.

How It Compares

The nearestRivals array is empty for this entry. Therefore, the record provides no rival name, no rival score, and no deltaPct value. It cannot be positioned against any named competitor using the supplied data. The only comparison anchor is the percentile against all CPUs, which is 50, and the average benchmark score of 0. The percentile places the CPU at the midpoint of the database’s all-CPU classification, but without individual benchmark scores or rival entries, no relative performance percentage can be stated.

A rival-by-rival comparison paragraph cannot be written because no nearest rivals are listed. The absence of any deltaPct field for a competitor is itself a finding: the database has not associated this CPU with a comparable part.
