AMD A8-7680 vs AMD Ryzen 5 PRO 2500U Comparison

The Verdict

The recorded data presents a clear performance hierarchy between these two AMD processors. The AMD Ryzen 5 PRO 2500U is the decisive winner in the single benchmark where both were measured directly, the Cinebench R15 multi-core test, scoring 553 against the AMD A8-7680's 303. That result represents a 45.2% advantage for the Ryzen part, a margin that defines the entire comparison. The A8-7680, with its four threads and Excavator architecture, sits at the 28th percentile of all CPUs, while the Ryzen 5 PRO 2500U also lands at the 28th percentile, yet the underlying scores tell different stories. The A8-7680 has an average benchmark score of 1036, while the Ryzen 5 PRO 2500U records 1024. These averages are close, but the direct head-to-head result shows the Ryzen part pulling ahead substantially in the one test they share. The A8-7680's nearest rivals include the AMD A10-7890K at a 0.1% delta, the Intel Core i7-4558U at -0.2%, and the AMD A10-9700 at 0.2%. The Ryzen 5 PRO 2500U's nearest rivals are the AMD Phenom II X6 1075T at 0% delta, the Intel Core i7-975 at 0.1%, the Intel Processor N150 at -0.1%, and the Intel Pentium Gold G5600 at 0.2%. The A8-7680 is a desktop part with a 45 watt TDP, while the Ryzen 5 PRO 2500U is a mobile processor with a 15 watt TDP, a difference that makes the Ryzen's performance advantage more notable given its far lower power envelope. For workloads that rely on multi-threaded throughput, the Ryzen 5 PRO 2500U is the clear choice. The A8-7680, however, offers a higher boost clock of 3.80 GHz against the Ryzen's 3.60 GHz, and it maintains a presence in the desktop socket ecosystem with DDR3 memory support. Users constrained to an AMD Socket FM2+ platform have no choice but the A8-7680, while those selecting a modern mobile platform would take the Ryzen 5 PRO 2500U without hesitation based on the Cinebench R15 result. The data does not support choosing the A8-7680 for raw compute performance.

Where Each One Wins

The AMD Ryzen 5 PRO 2500U wins the only direct comparison available. In Cinebench R15 multi-core, it scores 553 versus 303 for the A8-7680, a 45.2% lead. This is the sole head-to-head benchmark recorded, so any assessment of use-case splits must rely on the individual benchmark suites for each processor. The Ryzen 5 PRO 2500U also has a Cinebench R15 single-core score of 134, though the A8-7680 has no comparable single-core R15 number in the database. The Ryzen part shows additional strength in Geekbench, with a multi-core score of 2540 and a single-core score of 867. The A8-7680 counters with Cinebench R20 multi-core at 1264, R20 single-core at 178, R23 multi-core at 3011, and R23 single-core at 425. These are different test generations, so direct comparison is not possible, but the A8-7680 demonstrates it can produce competitive scores in newer rendering workloads. The A8-7680's base clock of 3.50 GHz and boost of 3.80 GHz exceed the Ryzen's 2.00 GHz base and 3.60 GHz boost. For single-threaded responsiveness in legacy applications, the A8-7680's higher clock rates could give it an edge, but the Ryzen's Zen architecture and higher thread count of 8 threads versus 4 gives the A8-7680 no advantage in heavily threaded software. The Ryzen 5 PRO 2500U integrates Radeon Vega 8 graphics, while the A8-7680 uses Radeon R7 graphics. Neither processor supports ECC memory. The Ryzen supports DDR4 with 38.4 GB/s bandwidth, while the A8-7680 supports DDR3 with 34.1 GB/s. The Ryzen 5 PRO 2500U is the winner for multi-threaded rendering and modern mobile workloads. The A8-7680 is the only option for FM2+ desktop builds and has a 3.80 GHz boost clock that may benefit lightly threaded tasks, though no direct single-core comparison exists to confirm that advantage.

Head-to-Head Benchmarks

The database contains a single direct head-to-head benchmark between these two processors, and it is decisive. In Cinebench R15 multi-core, the AMD Ryzen 5 PRO 2500U scores 553, while the AMD A8-7680 scores 303. The delta percentage is -45.2%, indicating the A8-7680 trails by that margin. This is the only test where both chips were measured on identical terms, and the result is unambiguous. The Ryzen 5 PRO 2500U outperforms the A8-7680 by nearly half in this rendering workload, a gap that reflects the architectural gulf between Excavator and Zen.

Looking beyond the direct comparison, the A8-7680's benchmark suite reveals its own strengths. In Cinebench R20 multi-core, the A8-7680 scores 1264, and in Cinebench R20 single-core it scores 178. In Cinebench R23 multi-core, the A8-7680 scores 3011, and in R23 single-core it scores 425. These are respectable numbers for a 4-thread desktop part, but they cannot be directly compared to the Ryzen's results because the Ryzen 5 PRO 2500U was measured on Cinebench R15 and Geekbench only. The Ryzen 5 PRO 2500U also records a Geekbench multi-core score of 2540 and a Geekbench single-core score of 867, giving it a balanced profile across different benchmark families.

The average benchmark scores place both processors very close in the broader database. The A8-7680 has an average score of 1036, and the Ryzen 5 PRO 2500U has an average score of 1024. The A8-7680's nearest rivals are the AMD A10-7890K with an average score of 1035 at a 0.1% delta, the Intel Core i7-4558U with 1038 at -0.2%, and the AMD A10-9700 with 1034 at 0.2%.
