Head-to-Head Benchmarks
The recorded head-to-head data covers five Cinebench tests, and the AMD PRO A8-8650B wins all five. The margins are tight but consistent, ranging from 7.8% to 8.7%.
In Cinebench R15 multi-core, the AMD scores 275 against the Atom's 255, a 7.8% advantage. This is the smallest margin in the set. In Cinebench R20 multi-core, the AMD scores 1148 against 1063, an 8% lead. In Cinebench R23 multi-core, the AMD scores 2734 against 2533, a 7.9% lead.
Single-core results follow the same trend. In Cinebench R20 single-core, the AMD scores 162 against 149, an 8.7% lead. This is the largest win for the AMD part across all tests. In Cinebench R23 single-core, the AMD scores 386 against 357, an 8.1% lead.
The average benchmark score for the AMD part is 887, which places it at the 24th percentile of all CPUs. The Atom's average score is 871, placing it at the 23rd percentile. The AMD part's nearest rival by average score is the Intel Pentium G4560T at 887, with a 0% delta. The Atom's nearest rival is the AMD Athlon PRO 3045B at 872, with a 0.1% delta.
The data indicates a consistent performance edge for the AMD PRO A8-8650B across both single-core and multi-core Cinebench workloads. The Intel Atom C5315, despite its smaller process node and lower TDP, does not overtake the AMD part in any recorded benchmark. The AMD part's higher clock speeds, with a base of 3.20 GHz and boost of 3.90 GHz versus the Atom's 2.40 GHz base, likely contribute to its lead. The Atom counters with DDR4 memory support and a higher theoretical memory bandwidth of 38.9 GB/s, though this does not translate into a benchmark win in the recorded tests.
