Analysis: AMD A8-7680 vs AMD PRO A10-8770
The AMD PRO A10-8770 and AMD A8-7680 are nearly identical silicon, sharing the same Excavator architecture, 28 nm process node, and a 4-core/4-thread configuration. The benchmark data, however, shows a consistent, if narrow, edge for the PRO A10-8770 across every single test in the head-to-head comparison. The PRO A10-8770 wins all five Cinebench tests, with the largest margin being a 1.1% lead in Cinebench R20 single-core (180 vs 178). The smallest margin is a 0.9% lead in both Cinebench R20 multi-core (1276 vs 1264) and Cinebench R23 single-core (429 vs 425). These are not transformative differences, but they are uniform.
Head-to-Head Benchmarks
The data paints a picture of a tightly contested match where the PRO A10-8770 emerges as the victor in every discipline. The largest single-core advantage appears in Cinebench R20, where the PRO A10-8770 scores 180 against the A8-7680's 178, a 1.1% delta. This is mirrored in the multi-core tests, where the PRO A10-8770's 1276 in Cinebench R20 outpaces the A8-7680's 1264 by 0.9%. The Cinebench R23 results follow the same pattern: the PRO A10-8770 posts 3040 versus 3011 in multi-core (a 1% delta) and 429 versus 425 in single-core (a 0.9% delta). The oldest test in the suite, Cinebench R15 multi-core, shows the PRO A10-8770 at 306 against the A8-7680's 303, a 1% difference.
While the deltaPct values are small, they are remarkably consistent. The PRO A10-8770 is never trailing. This suggests a fundamental, if slight, performance advantage that scales across both single-threaded and multi-threaded workloads. The average benchmark score reinforces this narrative, with the PRO A10-8770 averaging 1046 compared to the A8-7680's 1036. This places the PRO A10-8770 at the 29th percentile of all CPUs, while the A8-7680 sits at the 28th percentile. In practical terms, the data indicates that in any given Cinebench run, the PRO A10-8770 will deliver a marginally higher score, but the difference is likely to be imperceptible in real-world usage.

Architecture Differences
Both processors are built on the same fundamental architecture, which explains their similar performance. They share the Excavator microarchitecture, the Carrizo codename, and are manufactured on a 28 nm process node by GlobalFoundries. Both have 3,100 million transistors on a 250 mm² die, a 320 KB L1 cache, and a 2 MB L2 cache. There is no L3 cache on either chip. The integrated graphics are also identical, with both featuring a Radeon R7.
The key architectural differences lie in the platform support. The AMD PRO A10-8770 uses the AMD Socket AM4 and supports DDR4 memory with a dual-channel bus. The AMD A8-7680, in contrast, uses the AMD Socket FM2+ and supports DDR3 memory, also on a dual-channel bus. This leads to a difference in theoretical memory bandwidth: the PRO A10-8770 has 38.4 GB/s, while the A8-7680 has 34.1 GB/s. This memory bandwidth advantage is a likely contributor to the PRO A10-8770's consistent, albeit small, benchmark wins. Both processors have the same base clock of 3.50 GHz and boost clock of 3.80 GHz, and neither has an unlocked multiplier. They both support PCIe Gen 3 and do not support ECC memory.
The Verdict
Based strictly on the performance data, the AMD PRO A10-8770 is the superior processor. It wins every head-to-head benchmark, has a higher average score (1046 vs 1036), and a higher percentile ranking (29th vs 28th). The performance delta is small, but it is consistent across all tests. Therefore, for any user prioritizing raw compute performance in Cinebench workloads, the data clearly points to the PRO A10-8770.
However, the A8-7680 is not without its own merits. The most significant advantage it holds is its TDP of 45 watts, which is 20 watts lower than the PRO A10-8770's 65 watts. This makes the A8-7680 a more power-efficient option. For a system where thermal output and power consumption are primary concerns, the A8-7680 is the better choice, accepting a small performance trade-off. The choice comes down to a simple trade-off: maximum benchmark performance versus lower power draw. The PRO A10-8770 is the performance pick; the A8-7680 is the efficiency pick.

Where Each One Wins
The AMD PRO A10-8770 wins in all performance-oriented categories. It has a higher score in every Cinebench test, including multi-core and single-core variants across R15, R20, and R23. Its higher memory bandwidth (38.4 GB/s vs 34.1 GB/s) and support for DDR4 memory give it a platform-level advantage. It also holds a higher average benchmark score (1046 vs 1036) and a higher percentile ranking (29 vs 28). Any workload that is sensitive to CPU compute or memory throughput will favor the PRO A10-8770.
The AMD A8-7680 wins in the power efficiency category. Its TDP of 45 watts is significantly lower than the PRO A10-8770's 65 watts. This makes it the preferable option for compact, low-power, or thermally constrained builds where the reduction in power draw is more important than the marginal performance gain. It also has a later release date (2018-10-25) compared to the unspecified release date of the PRO A10-8770. In all other measurable aspects, the PRO A10-8770 is the clear winner.
