AMD A10-7860K vs AMD PRO A8-8650B Comparison

The AMD A10-7860K and AMD PRO A8-8650B are both 4-core, 4-thread desktop processors built on the same Steamroller architecture, code-named Godaveri, and manufactured on a 28 nm process by GlobalFoundries. Both use the AMD Socket FM2+ platform, feature the same 2,411 million transistors, the same 245 mm² die size, and identical cache configurations: 256 KB of L1 cache and 4 MB of L2 cache. Both support DDR3 memory in a dual-channel configuration with 34.1 GB/s of memory bandwidth, lack ECC support, and offer PCIe Gen 3 with 16 lanes from the CPU. The integrated graphics on both is a Radeon R7, and both carry a 65 W TDP. The database records seven direct head-to-head comparisons between these two parts, and the A10-7860K wins all seven. The average benchmark score for the A10-7860K is 904, while the PRO A8-8650B averages 887. The following analysis details where each part stands based strictly on recorded measurements.

Head-to-Head Benchmarks

The most significant margin between the two processors appears in the Geekbench multi-core test. The A10-7860K scores 1103, while the PRO A8-8650B scores 1060. That is a 4.1% difference, the largest relative gap in any recorded benchmark. This suggests that when all four cores are engaged in a workload that scales well across threads, the A10-7860K pulls ahead by a noticeable margin. The PRO A8-8650B trails by 43 points in that test, which is not a trivial gap for two processors with otherwise identical core counts and thread counts.

In the Cinebench R15 multi-core test, the A10-7860K scores 279 against 275 for the PRO A8-8650B, a 1.5% lead. The Cinebench R20 multi-core test shows a slightly larger edge: the A10-7860K scores 1166, while the PRO A8-8650B scores 1148, a 1.6% difference. The Cinebench R23 multi-core test repeats that pattern, with the A10-7860K scoring 2778 and the PRO A8-8650B scoring 2734, again a 1.6% gap. Across all three Cinebench multi-core versions, the A10-7860K maintains a consistent, if modest, advantage of roughly one and a half to two percent.

Single-core performance tells a similar story, though with smaller absolute differences. In Cinebench R20 single-core, the A10-7860K scores 164 versus 162 for the PRO A8-8650B, a 1.2% lead. In Cinebench R23 single-core, the A10-7860K scores 392 and the PRO A8-8650B scores 386, a 1.6% margin. Geekbench single-core shows the A10-7860K at 447 and the PRO A8-8650B at 441, a 1.4% difference. None of these single-core gaps are large, but they are consistent: the A10-7860K is ahead in every single-threaded measurement recorded.

The overall win tally is 7 for the A10-7860K and 0 for the PRO A8-8650B. That is a clean sweep in the head-to-head data. The largest single delta is the 4.1% Geekbench multi-core result, while the smallest is the 1.2% Cinebench R20 single-core result. The other five tests fall between 1.4% and 1.6%. This uniformity across different rendering engines and general-purpose benchmarks indicates that the A10-7860K has a small but repeatable performance advantage in every workload category represented in the database.

The Verdict

The recorded data points to a straightforward conclusion: the AMD A10-7860K outperforms the AMD PRO A8-8650B in every benchmark test where both have been measured. The average benchmark score of 904 for the A10-7860K compares to 887 for the PRO A8-8650B, a difference of 17 points, or roughly 1.9% on the average. The A10-7860K also sits at the 24th percentile of all CPUs tracked, and the PRO A8-8650B sits at the same 24th percentile, so both parts occupy a similar position in the overall performance distribution. Neither processor is a standout in the broader CPU landscape, but within this pairing, the A10-7860K is the clear winner.

For a user choosing between these two, the data suggests the A10-7860K is the better pick if raw performance is the only criterion. The Geekbench multi-core result, where the A10-7860K leads by 4.1%, indicates that applications that can use all four cores will see the biggest benefit from choosing the A10-7860K. Single-threaded workloads also favor the A10-7860K, though the margin is smaller, ranging from 1.2% to 1.6% depending on the test.

The PRO A8-8650B does not win any benchmark in the head-to-head set. Its recorded scores are consistently lower, but not dramatically so. The largest deficit is 43 points in Geekbench multi-core, and the smallest is 2 points in Cinebench R20 single-core. For a user who already owns a PRO A8-8650B, the performance difference is unlikely to be transformative in everyday use, but for a new purchase, the A10-7860K offers a measurable advantage across the board.

A: No. In the seven head-to-head benchmarks recorded, the A10-7860K wins all seven. The PRO A8-8650B has zero wins.

Specification Differences

The base clock differs between the two parts. The A10-7860K runs at 3.60 GHz, while the PRO A8-8650B runs at 3.20 GHz. The boost clock also differs, with the A10-7860K reaching 4.00 GHz and the PRO A8-8650B reaching 3.90 GHz. Both have a 65 W TDP, so the higher clocks on the A10-7860K do not come with an increased thermal design power.

The multiplier is unlocked on the A10-7860K, while the PRO A8-8650B has a locked multiplier. This means the A10-7860K allows user-directed overclocking, whereas the PRO A8-8650B does not. The part numbers also differ, with the A10-7860K listed as AD786KYBJABOXAD786KYBJCSBXAD786KYBI44JC and the PRO A8-8650B as AD865BYBI44JC.

The release dates in the database are different. The A10-7860K has a release date of 2016-02-01, while the PRO A8-8650B has a release date of 2015-09-28. Both are marked as end-of-life production status, and both are in the desktop market segment.

Architecture Differences

The two processors share the same underlying architecture. Both use the Steamroller architecture with the Godaveri codename, and both are fabricated on a 28 nm process at GlobalFoundries. The transistor count is identical at 2,411 million, and the die size is identical at 245 mm².

Cache configurations match exactly. Both have 256 KB of L1 cache and 4 MB of L2 cache, with no L3 cache present. Memory support is the same: DDR3, dual-channel, with 34.1 GB/s of memory bandwidth. ECC memory is not supported on either part. PCIe connectivity is also identical: Gen 3 with 16 lanes from the CPU.

The integrated graphics are the same Radeon R7 on both processors. The socket is the same, AMD Socket FM2+. The generation label differs only by branding: the A10-7860K is listed as A10 (Godaveri), while the PRO A8-8650B is listed as A8 (Godaveri). Functionally, the architectural specifications are indistinguishable between the two, apart from clock speeds and the unlocked multiplier on the A10-7860K.

Where Each One Wins

The A10-7860K wins in every benchmark category recorded. In multi-core workloads, it leads by percentages ranging from 1.5% in Cinebench R15 to 4.1% in Geekbench multi-core. This makes it the better choice for rendering tasks, video encoding, or any application that can utilize all four cores. The Cinebench R23 multi-core score of 2778 versus 2734 reinforces this, as does the Cinebench R20 multi-core score of 1166 versus 1148.

In single-core workloads, the A10-7860K also wins, though the margins are tighter. The Cinebench R23 single-core score is 392 against 386, and the Geekbench single-core score is 447 against 441. For users running older software that relies on a single thread, the A10-7860K still offers a slight edge, but the difference is less pronounced than in multi-threaded tasks.

The PRO A8-8650B does not win a single recorded benchmark. Its only potential advantage lies outside the performance data: it has a locked multiplier, which could be seen as a feature for systems where overclocking is undesirable. However, that is not a performance win, and the database shows no test where the PRO A8-8650B comes out ahead. For any user prioritizing measured performance, the A10-7860K is the only choice between these two. The data is unambiguous: 7 wins for the A10-7860K, 0 for the PRO A8-8650B.
