AMD A10-7860K vs AMD Ryzen Embedded R1305G Comparison

The Verdict

The recorded data presents an unusually clear split between these two AMD processors. The AMD A10-7860K wins every single head-to-head benchmark in the database, taking all five Cinebench comparisons with margins ranging from 3.6% to 3.9%. The Ryzen Embedded R1305G, despite being a much newer design on a smaller process node, does not overcome the A10-7860K’s higher clock speeds and additional physical cores in any tested workload.

The A10-7860K is the correct choice for anyone who needs maximum compute performance from a desktop platform. Its four Steamroller cores at a 3.60 GHz base and 4.00 GHz boost clock deliver consistently higher scores across every Cinebench iteration, both single-core and multi-core. The Ryzen Embedded R1305G, with two Zen cores and four threads at a 1.50 GHz base and 2.80 GHz boost, trails by roughly 4% in every test. That is a narrow margin, but it is a universal one.

However, the R1305G has its own clear role. Its 10 W TDP versus the A10-7860K’s 65 W TDP makes it suitable for low-power embedded systems where thermal and energy constraints matter more than raw throughput. The A10-7860K is marked as end-of-life, while the R1305G remains in active production. Buyers building new systems today should favor the R1305G for availability and power efficiency, while those upgrading an existing FM2+ platform or seeking maximum performance per socket should choose the A10-7860K.

The average benchmark scores confirm the closeness: the R1305G averages 919 points across its tested workloads, while the A10-7860K averages 904. Both sit at the 24th percentile versus all CPUs in the database. The R1305G’s nearest rivals include the AMD PRO A10-9700E at an identical 919 average score, while the A10-7860K sits within 0.4% of Intel Core i3-4330T and within 0.2% of Intel Core i5-4258U.

Where Each One Wins

The A10-7860K wins outright in every benchmark category recorded. In Cinebench R15 multi-core, it scores 279 versus 269 for the R1305G, a 3.6% advantage. In Cinebench R20 multi-core, 1166 versus 1121, a 3.9% gap. The single-core tests follow the same pattern: R20 single-core shows 164 versus 158 (3.7% ahead), and R23 single-core shows 392 versus 377 (3.8% ahead). The R23 multi-core result is 2778 versus 2670, again 3.9% ahead.

The R1305G’s wins are not in benchmark scores but in platform characteristics. It draws just 10 W of power, compared to 65 W for the A10-7860K. It uses DDR4 memory with 38.4 GB/s bandwidth, while the A10-7860K is limited to DDR3 at 34.1 GB/s. The R1305G is built on a 14 nm process with 3,500 million transistors on a 148 mm² die, versus the A10-7860K’s 28 nm process with 2,411 million transistors on a 245 mm² die. The R1305G also remains in active production, while the A10-7860K has reached end-of-life status.

For users who prioritize raw compute, the A10-7860K is the clear winner. For users who prioritize power efficiency, modern memory support, or ongoing availability, the R1305G offers those advantages despite its slight performance deficit.

Architecture Differences

The two processors represent entirely different eras of AMD design. The R1305G uses the Zen architecture, codenamed Banded Kestrel, built on a 14 nm process at GlobalFoundries. It has 2 cores and 4 threads, with a base clock of 1.50 GHz and a boost clock of 2.80 GHz. Its cache layout includes 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The A10-7860K uses the Steamroller architecture, codenamed Godaveri, built on a 28 nm process. It has 4 cores and 4 threads, with a base clock of 3.60 GHz and a boost clock of 4.00 GHz. Its cache consists of 256 KB of L1 and 4 MB of L2, with no L3 cache.

The transistor counts and die sizes reflect the process differences. The R1305G packs 3,500 million transistors into 148 mm², while the A10-7860K uses 2,411 million transistors across 245 mm². The R1305G’s smaller, denser design allows for its dramatically lower 10 W TDP, whereas the A10-7860K requires 65 W.

Memory support differs as well. The R1305G uses dual-channel DDR4 with 38.4 GB/s bandwidth, while the A10-7860K uses dual-channel DDR3 with 34.1 GB/s bandwidth. Neither supports ECC memory, according to the recorded data. The R1305G provides 8 PCIe Gen 3 lanes from the CPU, while the A10-7860K provides 16 PCIe Gen 3 lanes.

Integrated graphics also differ: the R1305G bundles Radeon Vega 3 graphics, while the A10-7860K includes Radeon R7 graphics. The R1305G uses the AMD Socket FP5, while the A10-7860K uses the AMD Socket FM2+. The A10-7860K has an unlocked multiplier, allowing overclocking, while the R1305G does not. The R1305G was released in February 2020; the A10-7860K was released in February 2016.

Head-to-Head Benchmarks

The head-to-head data is one-sided. The A10-7860K wins all five recorded comparisons, with no wins for the R1305G.

In Cinebench R15 multi-core, the A10-7860K scores 279 against 269 for the R1305G, a 3.6% advantage. This test, which stresses all available cores, shows the A10-7860K’s four physical Steamroller cores overcoming the R1305G’s two Zen cores with simultaneous multithreading. The R1305G’s lower base clock of 1.50 GHz likely limits its throughput in this workload, despite the architectural efficiency of Zen.

Cinebench R20 multi-core shows a similar outcome: 1166 for the A10-7860K versus 1121 for the R1305G, a 3.9% gap. The R20 test is more demanding than R15, yet the relative margin remains nearly identical, suggesting the performance difference scales consistently with workload complexity.

Single-core results follow the same pattern. In Cinebench R20 single-core, the A10-7860K scores 164 versus 158 for the R1305G, a 3.7% lead. In Cinebench R23 single-core, the A10-7860K scores 392 versus 377, a 3.8% lead. These margins indicate that even in lightly threaded workloads, the A10-7860K’s higher clock speeds (3.60 GHz base, 4.00 GHz boost) outweigh the R1305G’s architectural advantages. The R1305G’s boost clock is 2.80 GHz, which is 1.20 GHz lower than the A10-7860K’s boost speed.

The final head-to-head test, Cinebench R23 multi-core, shows 2778 for the A10-7860K versus 2670 for the R1305G, a 3.9% margin. This confirms the pattern: the A10-7860K is consistently ahead by roughly 4% across every benchmark, regardless of core count or test generation.

The database also records additional Geekbench results for the A10-7860K only: 1103 in multi-core and 447 in single-core. No corresponding Geekbench scores exist for the R1305G in the recorded data, so direct comparison on that test is not possible.

In summary, the A10-7860K is the faster processor in every measured dimension. Its wins are narrow but absolute. The R1305G’s case rests entirely on power efficiency, modern memory support, and production status, not on benchmark performance.
