AMD Ryzen 7 7435HS vs Intel Core i7-1280P Comparison

The data presents a clear split: the AMD Ryzen 7 7435HS decisively outperforms the Intel Core i7-1280P in the majority of benchmark tests, winning 11 of 17 head-to-head comparisons. However, the Intel chip secures specific victories in single-threaded and specialized workloads, making the choice dependent on the intended use case. The Ryzen 7 7435HS’s dominance in multi-core and sustained throughput tests is the defining narrative, while the Intel Core i7-1280P counters with notable strengths in physics simulation and prime number processing.

Head-to-Head Benchmarks

The most striking result is in Cinebench R23 multi-core, where the AMD Ryzen 7 7435HS scores 19,873 against the Intel Core i7-1280P’s 11,666. This is a 41.3% advantage for AMD, a massive gap that underscores the Ryzen’s superior multi-threaded capability. The pattern holds in Cinebench R20 multi-core, with AMD winning 8,346 to 7,153 (a 14.3% delta), though the margin narrows considerably. In the older Cinebench R15 multi-core test, the Intel chip actually wins, scoring 2,112 versus 2,003, a 5.4% edge, suggesting the Intel processor’s performance scales differently across workload generations.

Single-core results tell a different story. In Cinebench R23 single-core, the AMD Ryzen 7 7435HS leads with 2,805 points versus Intel’s 1,651, a 41.1% margin. This is echoed in Cinebench R20 single-core (1,178 vs 1,009, a 14.3% delta) and Cinebench R15 single-core (282 vs 238, a 15.6% delta). However, in PassMark’s single-thread test, the Intel Core i7-1280P wins 3,316 to 3,167, a 4.7% advantage. This divergence indicates that while AMD has the higher peak single-core performance in rendering workloads, Intel holds a slight edge in the PassMark single-thread metric.

Beyond Cinebench, the AMD Ryzen 7 7435HS wins heavily in data processing tasks. PassMark data compression shows AMD at 310,038 versus Intel’s 220,621, a 28.8% lead. Data encryption follows a similar path, with AMD at 18,648 versus 13,179, a 29.3% gap. The extended instructions test is another blowout, with AMD scoring 21,690 against Intel’s 12,897, a 40.5% delta. Integer math also favors AMD, 85,274 to 75,485 (an 11.5% win), and random string sorting goes to AMD at 31,827 versus 24,308, a 23.6% advantage. The PassMark multithread score confirms the trend, with AMD at 23,393 and Intel at 20,168, a 13.8% delta.

The Intel Core i7-1280P’s wins are narrower but significant in specific areas. The largest is in PassMark find prime numbers, where Intel scores 86 to AMD’s 54, a 59.3% blowout. PassMark physics also goes to Intel, 1,411 to 991, a 42.4% margin. Floating point math is a closer affair, with Intel winning 51,355 to 48,863, a 5.1% edge. These results suggest Intel’s architecture excels in integer-heavy prime calculation and physics simulation, while AMD dominates in broader multi-core and data compression workloads.

The Verdict

The benchmark evidence points decisively to the AMD Ryzen 7 7435HS as the superior processor for most users. Its 41.3% lead in Cinebench R23 multi-core and 40.5% lead in extended instructions are not marginal differences; they represent a generational leap in processing power for demanding applications. The Ryzen 7 7435HS also wins the PassMark multithread test by 13.8%, reinforcing its suitability for heavily threaded tasks like video rendering, software compilation, and scientific computing.

The Intel Core i7-1280P is not without merit. Its 59.3% victory in find prime numbers and 42.4% win in physics simulation indicate specific strengths that could be relevant for niche workloads. The 4.7% PassMark single-thread win also shows it can hold its own in lightly threaded scenarios. However, given that the Ryzen 7 7435HS wins 11 of 17 head-to-head tests and secures the most critical multi-core benchmarks, the data recommends AMD for general-purpose high-performance computing. Users who prioritize prime number processing or physics simulation might favor Intel, but these are narrow use cases.

Both processors sit at the 78th percentile of all CPUs, and their average benchmark scores are nearly identical: 26,469 for Intel and 26,402 for AMD. The nearest rival data confirms this parity, with the Intel Core i9-12900HK matching Intel’s score exactly and the AMD Ryzen 5 8640U trailing by 0.3% for Intel while leading AMD by 0.2%. This means the overall performance envelope is similar, but the distribution of strengths is heavily skewed toward AMD in multi-core and Intel in specialized single-thread tasks.

Where Each One Wins

For multi-threaded productivity, the AMD Ryzen 7 7435HS is the clear winner. The 41.3% Cinebench R23 multi-core lead and 28.8% data compression advantage make it the better choice for video editing, 3D rendering, and large dataset manipulation. The 40.5% extended instructions win also suggests AMD excels in workloads using advanced CPU instructions, such as cryptography or signal processing. The 11.5% integer math lead further solidifies AMD’s position for general computational tasks.

The Intel Core i7-1280P wins in physics simulation, with a 42.4% margin in PassMark physics, indicating it is better suited for physics-based calculations in engineering or gaming physics engines. Its 59.3% lead in find prime numbers points to a strength in cryptographic key generation or mathematical research. The 5.1% floating point math win and 4.7% PassMark single-thread win suggest Intel has a slight edge in floating-point-heavy applications and some single-threaded legacy software.

In mixed workloads, the PassMark multithread test shows AMD ahead by 13.8%, meaning AMD should handle simultaneous tasks like streaming while gaming or running multiple virtual machines more smoothly. However, the Intel chip’s PassMark single-thread performance is 4.7% higher, which could translate to faster response times in applications that are not optimized for many cores.
