AMD Ryzen 5 2600X vs Intel Core i5-12500H Comparison

The AMD Ryzen 5 2600X and the Intel Core i5-12500H represent two distinct approaches to processor design, separated by several generations of architecture and market positioning. The data shows a decisive performance hierarchy, yet the underlying reasons for that hierarchy reveal significant differences in core counts, process technology, and intended use cases. The Ryzen 5 2600X, a desktop part from the 2000 series, faces the mobile-focused Core i5-12500H from Intel's 12th Gen lineup, and the benchmark results are overwhelmingly one-sided.

Head-to-Head Benchmarks

The head-to-head comparison yields a clean sweep for the Intel Core i5-12500H, winning all 13 shared benchmark tests. The margins are substantial across the board, but the magnitude varies significantly by workload type. The largest gap appears in floating-point math, where the Intel part scores 52227 against the AMD's 24270, a delta of -53.5% for the Ryzen 5 2600X. This means the i5-12500H is more than twice as fast in this specific test, a result that speaks to the efficiency of its newer microarchitecture.

In integer math, the Intel chip also demonstrates a commanding lead with a score of 71714 versus 47377, a -33.9% delta. The pattern holds for more general multi-threaded workloads. In the Cinebench R15 multicore test, the i5-12500H posts 1999 points, while the Ryzen 5 2600X manages 1341, resulting in a -32.9% delta. The single-core Cinebench R15 result is even more lopsided, with Intel's 282 points dwarfing AMD's 163, a -42.2% difference. This single-threaded advantage is a critical finding, as it impacts everything from everyday responsiveness to lightly-threaded applications.

The PassMark suite offers a granular view of these differences. The i5-12500H wins data compression (253431 vs 198785, -21.6%) and random string sorting (28099 vs 22911, -18.5%), showing a clear lead in memory and cache-sensitive operations. The extended instructions test sees the Intel part score 14965 versus 7581, a -49.3% delta. Even in data encryption, where the Ryzen part is relatively closer, the i5-12500H still wins with 14749 against 13133, an -11% delta. The overall PassMark multithread score reinforces the trend: 20625 for Intel versus 13893 for AMD, a -32.6% gap. The physics test shows a similar story, with Intel's 1018 points beating AMD's 695, a -31.7% delta. Across every metric, the i5-12500H is faster, often by a wide margin.

Where Each One Wins

Given the zero wins for the AMD Ryzen 5 2600X in the head-to-head tests, the "where each one wins" analysis is a question of degree rather than categorical victories. The Intel Core i5-12500H wins everywhere, but its advantage is not uniform. The smallest margin of victory is in data encryption, where it is only 11% faster. This suggests that the Ryzen 5 2600X's older Zen architecture is comparatively stronger in cryptographic workloads, likely due to its dedicated AES instructions, even though it still trails.

The Intel part's biggest wins are in floating-point math (53.5% ahead) and extended instructions (49.3% ahead). These are areas where the newer Alder Lake architecture, with its support for AVX2 and other modern instruction sets, provides a massive advantage. For workloads that rely heavily on these features, such as scientific computing, video encoding, or 3D rendering, the i5-12500H is the clear choice. The Ryzen 5 2600X's best relative performance is in the data encryption test, where the gap narrows to 11%, but it still loses. In single-threaded performance, the Intel part is 30.3% ahead in PassMark and 42.2% ahead in Cinebench R15, highlighting the generational leap in per-core performance. The data shows no scenario in which the AMD chip is the better performer, only scenarios where the performance gap is smaller.

The Verdict

The verdict from the data is unambiguous: the Intel Core i5-12500H is the superior processor in every benchmark category measured. With 13 wins out of 13 head-to-head tests and an average benchmark score of 22625, it edges out the Ryzen 5 2600X's average of 22823 in the rival comparison, yet this is misleading. The head-to-head deltas show a consistent 18.5% to 53.5% advantage for Intel in specific tests. The i5-12500H's 76th percentile ranking among all CPUs matches the Ryzen 5 2600X's 76th percentile, but the raw performance scores tell a different story.

For a user building a new system, the i5-12500H is the only rational choice based on performance alone. It offers significantly better single-core, multi-core, and instruction-heavy performance. The Ryzen 5 2600X, while an active product with a launch MSRP of $229, is a legacy desktop part that cannot keep pace. The data suggests that the i5-12500H is better for any task, from gaming to content creation to general productivity. The only caveat is platform: the Ryzen 5 2600X uses the AMD Socket AM4, while the i5-12500H uses the Intel BGA 1744 socket, indicating the former is a socketed desktop CPU and the latter is a mobile BGA part, which may limit its use to laptops or mini-PCs. However, from a pure performance standpoint, the Intel part wins decisively.

This is a hybrid architecture, featuring a mix of performance and efficiency cores, totaling 12 cores and 16 threads.

The cache layouts differ notably. The AMD CPU has a per-core L1 cache of 96 KB and a per-core L2 cache of 512 KB, with a shared L3 cache of 16 MB. The Intel CPU has a smaller per-core L1 cache of 80 KB but a much larger per-core L2 cache of 1.25 MB, and a larger shared L3 cache of 18 MB. The transistor count and die size also differ, with the AMD part having 4,800 million transistors on a 213 mm² die, while the Intel part's transistor count is not listed but its die size is 217 mm². The Intel processor also includes integrated Iris Xe 80EU graphics, which the AMD processor lacks entirely.

The memory support is another key difference. The AMD Ryzen 5 2600X supports only DDR4 memory with a dual-channel bus and a memory bandwidth of 46.9 GB/s. The Intel Core i5-12500H supports both DDR4 and DDR5 memory, also on a dual-channel bus, but its memory bandwidth is not listed. The PCIe support also differs, with the AMD part using Gen 3 with 16 lanes (CPU only), while the Intel part uses Gen 4 with 20 lanes (CPU only). The AMD processor has an unlocked multiplier, whereas the Intel processor's multiplier is locked.
