AMD Ryzen 5 3600X vs Intel Core i5-12500H Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear overall winner, but the margin varies significantly by workload. Across the 17 head-to-head comparisons recorded in the database, the Intel Core i5-12500H takes 15 wins, while the AMD Ryzen 5 3600X manages only 2. The most decisive Intel victories come in floating-point math, where the i5-12500H scores 52,227 against 29,339 for the Ryzen, a 78% advantage. Integer math follows the same pattern, with the Intel part scoring 71,714 versus 49,934, a 43.6% lead. These are not small margins; they represent a fundamental difference in how each processor handles arithmetic-heavy workloads.

The Cinebench suite shows a remarkably consistent pattern. Across all six Cinebench tests (R15, R20, and R23, each in single-core and multi-core variants), the i5-12500H wins by nearly the same margin every time. The delta hovers between 28.6% and 28.8% for every Cinebench test. For example, in Cinebench R23 multi-core, the Intel chip scores 19,840 against 15,430 for the AMD, a 28.6% lead. In single-core R23, the scores are 2,801 versus 2,178, again a 28.6% gap. This consistency suggests the advantage is structural, not workload-specific.

PassMark tests show a more varied picture. The i5-12500H leads in data compression (253,431 versus 224,318, a 13% edge), multithreaded performance (20,625 versus 18,154, a 13.6% edge), and random string sorting (28,099 versus 24,343, a 15.4% edge). The single-thread PassMark score favors Intel by 29%, with 3,418 versus 2,649. Data encryption and extended instructions are closer calls: the Intel chip wins by 3.5% and 1.3% respectively, which is within normal run-to-run variance.

The AMD Ryzen 5 3600X takes its two wins in specific niches. In the PassMark find-prime-numbers test, the Ryzen scores 110 versus 57 for Intel, meaning the AMD chip is 48.2% faster. This is a notable reversal, though it is a narrow test that measures a specific mathematical operation. In PassMark physics, the Ryzen scores 1,186 versus 1,018, a 14.2% lead. These wins do not offset the overall picture, but they show the Zen 2 architecture retains strengths in particular computational patterns.

Architecture Differences

The two processors come from different design philosophies and different market segments. The Intel Core i5-12500H is a mobile part built on the Alder Lake architecture, manufactured on a 10 nm process at Intel. It has 12 cores and 16 threads, using a hybrid design that combines performance and efficiency cores. The cache layout is generous: 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3. The chip supports both DDR4 and DDR5 memory in dual-channel mode, and it includes integrated Iris Xe graphics with 80 execution units. The socket is Intel BGA 1744, which means it is soldered to the motherboard, a typical arrangement for mobile processors.

The AMD Ryzen 5 3600X is a desktop part based on the Zen 2 architecture, built on a 7 nm process at TSMC. It uses 6 cores and 12 threads, which is fewer threads than the Intel chip. The cache configuration differs substantially: 64 KB of L1 per core, 512 KB of L2 per core, but a much larger 32 MB of shared L3. That larger L3 pool is a hallmark of the Zen 2 design and helps in certain cache-sensitive workloads. The Ryzen supports only DDR4 memory, not DDR5, and it has no integrated graphics, so it requires a discrete GPU. It uses the AMD Socket AM4, a long-lived desktop platform with an unlocked multiplier for overclocking. The transistor count is listed at 3,800 million, and the die size is 74 mm², compared to 217 mm² for the Intel part.

The process node difference is significant: 7 nm for AMD versus 10 nm for Intel. The Ryzen also has a higher base clock at 3.80 GHz versus 2.50 GHz for the Intel chip, though the boost clocks are closer: 4.40 GHz for AMD and 4.50 GHz for Intel. The TDP difference is stark: the Intel mobile chip is rated at 45 watts, while the AMD desktop chip is rated at 95 watts. This is a key consideration because the Intel part delivers more performance in many tests while consuming less power according to the specification, though the comparison is complicated by the different market segments.

Where Each One Wins

The Intel Core i5-12500H is the clear choice for most compute-heavy tasks. The data shows a dominant performance in floating-point math (78% ahead), integer math (43.6% ahead), and single-threaded workloads across every benchmark suite. This makes it strong for general productivity, software development, and any application that relies heavily on arithmetic operations. The Cinebench results, with a consistent 28.6% lead across all variants, indicate that both short and long rendering workloads will complete noticeably faster on the Intel chip. The 13% lead in data compression and 13.6% lead in multithreaded PassMark score also suggest good performance in file archiving and parallel workloads.

The AMD Ryzen 5 3600X wins in two specific areas that are worth noting. The 48.2% advantage in the find-prime-numbers test points to efficiency in certain integer-heavy algorithms that involve primality testing or similar modular arithmetic. The 14.2% lead in PassMark physics is harder to generalize, but it may indicate better performance in certain simulation or physics-calculation patterns. The Ryzen also has a larger L3 cache at 32 MB versus 18 MB, which could benefit workloads that repeatedly access a large dataset. However, the benchmark data does not show a consistent cache-related advantage across the tested workloads.

For gaming, the single-thread performance is often important. The Intel chip leads by 29% in PassMark single-thread and by 28.6% to 28.8% in Cinebench single-core tests. That advantage should translate to better frame pacing in CPU-bound scenarios, though the comparison is complicated by the fact that the Intel chip is mobile and the AMD chip is desktop. The Ryzen does have the higher base clock, which may help in lightly threaded scenarios, but the benchmark data does not support a general gaming advantage for the AMD part.

The Verdict

The data points to one clear conclusion: the Intel Core i5-12500H is the stronger processor in almost every measured category. It wins 15 of 17 head-to-head benchmarks, with margins ranging from a narrow 1.3% in extended instructions to a dominant 78% in floating-point math. The consistent 28.6% lead across the entire Cinebench suite indicates a broad architectural advantage in rendering and compute tasks. The 29% single-thread lead and 43.6% integer math lead reinforce that this is not a fluke of one benchmark.

The AMD Ryzen 5 3600X should be considered only for very specific workloads. If your application involves prime number calculations or physics simulations that match the PassMark patterns, the Ryzen's wins in those tests matter. The larger 32 MB L3 cache could also be relevant for cache-sensitive workloads, even though the benchmark data does not show a consistent advantage from it. The Ryzen also has an unlocked multiplier, which allows overclocking that could close some gaps in the right hands.

For general use, content creation, software development, and most gaming scenarios, the benchmark results favor the Intel Core i5-12500H. The lower TDP of 45 watts versus 95 watts also makes the Intel part more efficient in terms of performance per watt, though the comparison is not direct since one is a mobile chip and the other is desktop. If the choice is between these two processors for a new build, the recorded data says to pick the Intel part unless the specific AMD-favorable workloads are your primary use case.
