Head-to-Head Benchmarks

The head-to-head results leave no ambiguity about the relative performance of these two chips. The Intel Core i7-12700H wins all 11 recorded comparisons. The largest margin appears in the PassMark find prime numbers test, where the Intel chip scores 94 against 36 for the AMD part, a difference of 161.1%. The floating point math test shows a similar story: Intel scores 65075, AMD scores 25245, a 157.8% advantage. These two results indicate that the Intel part is far stronger in heavy mathematical and scientific workloads that scale with core count and parallel execution.

The multi-threaded PassMark test reinforces this pattern. The Intel Core i7-12700H scores 25615, while the AMD Ryzen 3 PRO 5355G scores 14033, a difference of 82.5%. The integer math test shows a 96.3% lead for Intel, with scores of 90106 and 45910 respectively. The physics test also favors Intel heavily: 1512 versus 701, a 115.7% margin.

The Verdict

The data points to a clear verdict for raw performance: the Intel Core i7-12700H is the stronger processor in every recorded benchmark. With 11 wins out of 11 head-to-head comparisons, it dominates in multi-threaded, math-heavy, and even single-threaded workloads. The margins are substantial in most tests, ranging from 49.9% in extended instructions to 161.1% in prime-number finding. The Intel chip also offers more cores, more threads, more cache, newer PCIe support, and broader memory compatibility.

The AMD Ryzen 3 PRO 5355G, however, is not without its own advantages. It has a higher base clock of 4.00 GHz, a smaller 7 nm process, ECC memory support, and a higher average benchmark score of 27382 compared to 26717 for the Intel chip. It also sits in the same 79th percentile among all CPUs, meaning both chips are competitive within their respective segments. The AMD part is a desktop processor on the AM4 socket, which makes it a different kind of product entirely. For a user building a compact desktop system with ECC memory support, the AMD chip is the only option of the two. For a user who needs maximum multi-threaded throughput, the Intel chip is the obvious pick.

Where Each One Wins

The Intel Core i7-12700H wins in almost every computational category. Its 14 cores and 20 threads give it a massive advantage in parallel workloads, as shown by the 82.5% lead in the multi-threaded PassMark test and the 96.3% lead in integer math. It is the better choice for rendering, video encoding, compilation, scientific simulation, and any workload that can use more than eight threads. The 161.1% lead in prime-number finding and the 157.8% lead in floating point math make it well suited to financial modeling, physics calculations, and other number-crunching tasks. Its 24 MB of L3 cache and DDR5 support add further headroom for memory-intensive applications. The mobile form factor also means it fits into laptops, making it a strong option for high-performance mobile workstations.

The AMD Ryzen 3 PRO 5355G wins in platform flexibility and specific workstation features. Its ECC memory support is a genuine advantage for systems that require error-correcting memory, which the Intel chip cannot offer. The higher base clock of 4.00 GHz helps in lightly threaded tasks, even though the Intel chip still leads in single-threaded tests. The 7 nm process and 10,700 million transistors on a 180 mm² die suggest a denser, potentially more power-efficient design in certain conditions. The desktop AM4 socket makes it a straightforward drop-in for existing AM4 boards. The higher average benchmark score of 27382 also suggests that, across a broad mix of workloads, the AMD part holds its own in its segment. For a user who values ECC, a desktop platform, and a compact 4-core design, the AMD chip is the appropriate choice, while the Intel chip is the performance leader across the board.
