About AMD A8-6600K

The AMD A8-6600K is an end-of-life desktop processor released on May 31, 2013, built for AMD Socket FM2. It belongs to the A8 (Richland) generation and uses the Piledriver architecture, with 4 cores and 4 threads, a 3.90 GHz base clock, and a 4.20 GHz boost clock. The cache layout is 192 KB of L1 and 4 MB of L2, with no L3 cache, and the chip includes a Radeon HD 8570D integrated GPU. It supports DDR3 memory, and its benchmark profile is anchored by an average score of 764 and a 20th-percentile ranking versus all CPUs.

How It Compares

Against the Intel Core i5-4200U, the A8-6600K posts an average benchmark score of 764 versus the rival’s 762, a 0.3% lead. That is the tightest comparison in the nearest-rival group.

Against the Intel Pentium Silver N5000, the A8-6600K averages 764 to 761, a 0.4% advantage. The two are effectively peers in the database.

Against the Intel Core i3-5020U, the A8-6600K scores 764 versus 760, giving it a 0.6% edge. The margin is still small enough that the two chips occupy the same performance neighborhood.

Against the Intel Core i5-4250U, the A8-6600K reaches 764 while the rival reaches 759, for a 0.7% lead. That is the largest delta among the nearest rivals, but it remains under one percentage point.

Single-Thread vs Multi-Thread Behavior

The Geekbench single-core score is 451, while the multi-core score is 1,076. The gap is large: the chip is considerably better at using all four threads than it is at delivering raw single-thread speed. For lightly threaded tasks, the 451 score is the governing number; for workloads that can spread across all four threads, the 1,076 score is the ceiling.

The average benchmark score of 764 sits between the two Geekbench results, which shows that the overall standing of the A8-6600K is shaped by both its single-core limitation and its multi-core output. The 3.90 GHz base clock and 4.20 GHz boost clock are high, but the single-core score indicates that clock speed alone does not make up for the architecture’s per-thread performance. In real workloads, this means a short single-thread burst will feel far less capable than a task that can keep all cores busy.

Who Should Consider It

For office-style work, the A8-6600K can handle spreadsheet, document, and web-based tasks that are not heavily threaded. The boost clock of 4.20 GHz helps responsiveness in bursty scenarios, but the 451 single-core score sets a modest ceiling for that type of work.

For content creation, the multi-core score of 1,076 is the relevant figure. Light or occasional parallel jobs may run acceptably, but the 20th-percentile ranking shows that demanding creation workloads are likely to be limited by this CPU. Buyers who plan for heavy rendering, encoding, or similar work should choose a CPU with a stronger multi-core result.

For gaming, the A8-6600K includes a Radeon HD 8570D integrated GPU, so a separate graphics card is not strictly required for display output. There are no gaming benchmarks in the data, so specific game performance cannot be verified here. The end-of-life production status and Socket FM2 platform also mean this chip is best suited to an existing FM2 system rather than a fresh long-term build.

FAQ

Q: Is the AMD A8-6600K overclockable?

A: Yes. The multiplier is unlocked, allowing the CPU to be adjusted on a compatible Socket FM2 motherboard.

Q: What memory does the A8-6600K support?

A: It supports DDR3 memory in a dual-channel configuration, with 29.9 GB/s of memory bandwidth. ECC memory is not supported.

Q: Does the A8-6600K have integrated graphics?

A: Yes. It includes a Radeon HD 8570D integrated GPU.

Q: What socket does the A8-6600K use?

A: It uses AMD Socket FM2.

Q: Is the A8-6600K still in production?

A: No. Its production status is end-of-life, and it was released on May 31, 2013.

Q: How does the A8-6600K compare to the Intel Core i5-4200U?

A: The A8-6600K has an average benchmark score of 764, while the Core i5-4200U has 762. The A8-6600K is 0.3% ahead, which makes the two effectively equivalent in the database.

Benchmark Performance

The A8-6600K’s Geekbench multi-core score is 1,076, and its Geekbench single-core score is 451. Together those produce an average benchmark score of 764. The 20th-percentile ranking means the majority of CPUs in the database score higher, so the overall placement is low rather than mid-pack.

Against its four nearest rivals, the A8-6600K is ahead by exactly the deltas listed in the data: 0.3% over the Core i5-4200U at 762, 0.4% over the Pentium Silver N5000 at 761, 0.6% over the Core i3-5020U at 760, and 0.7% over the Core i5-4250U at 759. The rival average scores are all close, and the deltas are all below one percentage point. This tells a clear story: the A8-6600K is the highest-scoring member of a very tight cluster, but it does not dominate any of these CPUs in a meaningful way.

The multi-core result of 1,076 is above the average benchmark score, while the single-core result of 451 is below it. That split is consistent with a CPU whose aggregate score is helped by its four-thread capacity and dragged down by weaker single-thread performance.

Platform and Compatibility

The A8-6600K is a desktop part for the AMD Socket FM2 platform, built on the Piledriver architecture under the Richland codename. It uses a 32 nm process at GlobalFoundries.

Memory support is DDR3, with a dual-channel bus and 29.9 GB/s of bandwidth. ECC memory is not supported. Expansion connectivity is PCIe Gen 2. The integrated Radeon HD 8570D covers graphics output, so an FM2 system built around this CPU does not inherently require a separate graphics adapter.

Because the production status is end-of-life, the Socket FM2 platform is not a path to modern CPU upgrades. An A8-6600K system is limited to FM2-era parts, and any move to a newer socket would require changing the motherboard. The unlocked multiplier does provide tuning flexibility within the FM2 platform.

Power and Thermals

The A8-6600K carries a 100 W TDP, placing it in the standard desktop thermal class. It is manufactured on a 32 nm process, with 1,303 million transistors on a 246 mm² die.

Cooling should be selected for the 100 W TDP envelope. The 32 nm process means the chip’s heat output is concentrated, so a cooler that cannot handle that thermal class will limit sustained performance. Because the multiplier is unlocked, raising the clock above the 4.20 GHz boost speed would increase thermal demands beyond the default envelope.
