AMD Ryzen 5 7545U vs Intel Core i7-1280P Comparison

The AMD Ryzen 5 7545U and Intel Core i7-1280P are both 28 W mobile processors, but they are built on fundamentally different philosophies. The AMD chip uses a modern 6-core/12-thread Zen 4 design, while the Intel part uses a hybrid 14-core/20-thread Alder Lake layout. Benchmark data shows a clear split: the AMD wins the majority of tests (12 of 17 head-to-head comparisons), but the Intel takes decisive victories in several math-heavy workloads. This breakdown focuses on where each processor is the better choice, based strictly on the measured scores.

Where Each One Wins

The Ryzen 5 7545U dominates in rendering and single-threaded workloads. Its Cinebench R23 multi-core score of 17253 is 47.9% higher than the Intel’s 11666, and its single-core result of 2435 beats the i7-1280P’s 1651 by 47.5%. This is a massive gap in both multi- and single-core rendering performance. The AMD also wins in data compression (238345 vs 220621, +8%), data encryption (14202 vs 13179, +7.8%), and extended instructions (17865 vs 12897, +38.5%). For any task that relies on modern instruction sets or compression/encryption, the Ryzen is clearly ahead.

The Intel Core i7-1280P takes the crown in raw math throughput. It leads in PassMark integer math (75485 vs 60206, +20.2%), floating-point math (51355 vs 36754, +28.4%), and physics (1411 vs 1057, +25.1%). It also wins the find prime numbers test (86 vs 68, +20.9%). These results suggest that the Intel’s higher core count (14 vs 6) and threads (20 vs 12) give it an edge in heavily parallel, pure-computation tasks that don’t benefit from the AMD’s architectural efficiency. The Intel also wins Cinebench R15 multi-core (2112 vs 1739, +17.7%), which is an older rendering benchmark that may favor the higher thread count.

Architecture Differences

The two chips are built on different nodes and designs. The Ryzen 5 7545U uses TSMC’s 4 nm process with a 137 mm² die and 20,900 million transistors. Its Zen 4 architecture, codenamed Phoenix2, features 6 cores and 12 threads. The Intel Core i7-1280P uses Intel’s 10 nm process with a larger 217 mm² die; its Alder Lake-P architecture has 14 cores and 20 threads. The Intel has larger per-core caches: 80 KB L1 and 1.25 MB L2 per core, versus 64 KB and 1 MB for the AMD. However, the AMD has a 16 MB shared L3 cache, while the Intel has 24 MB shared L3.

Memory support differs significantly. The AMD supports only DDR5 with dual-channel memory and a bandwidth of 89.6 GB/s, plus ECC memory support. The Intel supports both DDR4 and DDR5 in dual-channel, but its memory bandwidth is not listed in the data, and it lacks ECC support. The Intel offers more PCIe lanes: Gen 4 with 20 lanes (CPU only) versus Gen 4 with 14 lanes for the AMD. Both have integrated graphics, with the AMD using Radeon 740M and the Intel using Iris Xe 96EU, but no graphics benchmark scores are provided. The AMD also has a higher boost clock at 4.90 GHz versus the Intel’s 4.80 GHz, and a much higher base clock of 3.20 GHz versus 1.80 GHz.

The Verdict

The data clearly favors the Ryzen 5 7545U for most users. Its Cinebench R23 results are extraordinary: a 47.9% multi-core lead and a 47.5% single-core lead over the i7-1280P. The AMD also wins in compression, encryption, and extended instructions by substantial margins. The overall average benchmark score for the Ryzen is 26849, placing it at the 79th percentile of all CPUs, while the Intel averages 26469 at the 78th percentile. The AMD’s nearest rival, the Intel Core i7-1370P, is only 0.2% behind it, while the Intel i7-1280P is virtually tied with the Core i9-12900HK (0% delta).

Pick the Ryzen 5 7545U if you prioritize modern rendering workloads, single-thread performance, or any task using modern instruction extensions. Its 38.5% lead in extended instructions is a strong indicator for future-proofed applications. Pick the Intel Core i7-1280P only if your workflow is dominated by pure integer or floating-point math, such as certain scientific simulations or financial modeling, where its 20.2% and 28.4% leads respectively matter more. For general productivity, the Ryzen’s 8% compression win and 24.9% random string sorting win make it the more versatile choice.

Head-to-Head Benchmarks

The most striking result is in Cinebench R23. The Ryzen 5 7545U’s multi-core score of 17253 crushes the i7-1280P’s 11666, a 47.9% delta. The single-core gap is equally dramatic: 2435 versus 1651, a 47.5% lead for AMD. These are not marginal differences; they indicate a generational leap in per-clock efficiency. In Cinebench R20, the AMD wins both multi-core (7246 vs 7153, +1.3%) and single-core (1022 vs 1009, +1.3%), though by much smaller margins.

PassMark results show a different pattern. The Intel takes large wins in integer math (75485 vs 60206, +20.2%) and floating-point math (51355 vs 36754, +28.4%). It also leads in physics (1411 vs 1057, +25.1%) and find prime numbers (86 vs 68, +20.9%). These four wins are substantial and suggest the Intel’s 14-core design is effective for raw computational throughput. However, the AMD counters with wins in data compression (238345 vs 220621, +8%), data encryption (14202 vs 13179, +7.8%), and random string sorting (30358 vs 24308, +24.9%). The extended instructions test is a blowout for AMD: 17865 versus 12897, a 38.5% advantage.

In the overall multithread test, the AMD edges out a win with 20298 versus 20168, a 0.6% delta. The single-thread test also goes to AMD with 3673 versus 3316, a 10.8% lead. The Cinebench R15 results are the only other Intel win, with 2112 versus 1739, a 17.7% margin. Counting all 17 head-to-head tests, the AMD wins 12 and the Intel wins 5.
