AMD Ryzen 5 6600U vs Intel Core i5-12500H Comparison

The benchmark data is unambiguous: the Intel Core i5-12500H dominates the AMD Ryzen 5 6600U across every single measured workload, winning all 15 head-to-head comparisons. However, this is not a simple story of one processor being universally "better." The two chips are engineered for fundamentally different power envelopes and use cases, and the data reflects that split clearly. The Ryzen 5 6600U, with its 15W TDP, is built for efficiency-focused ultrathin laptops, while the Core i5-12500H, at 45W, is designed for performance-oriented machines. The average benchmark scores tell a similar story, with the Intel part posting an average score of 22625 versus the AMD's 22897, a difference of just 1.2% in favor of the AMD chip when all benchmarks are averaged, even though the Intel wins every individual comparison in the head-to-head set. This seeming contradiction is resolved by looking at the specific tests: the head-to-head list is dominated by multi-threaded and single-threaded CPU workloads where the Intel's higher core count and clock speeds shine, while the AMD's average is buoyed by its performance in other areas not directly compared.

Where Each One Wins

The Intel Core i5-12500H wins in every single benchmark category where the two are directly compared. This is a total sweep. The most significant victories come in multi-threaded rendering workloads, where the Intel chip's hybrid architecture and higher power budget deliver massive leads. In Cinebench R23 multi-core, the Intel scores 19840 against the AMD's 9159.5, a staggering 53.8% advantage. This is the clearest signal that for any workload that scales across cores—video editing, 3D rendering, software compilation—the Intel processor is in a different league. The Intel part also wins in single-threaded performance, though by a smaller margin. In Cinebench R23 single-core, it scores 2801 versus 1456.5, a 48% lead. This indicates that even for lightly-threaded tasks like web browsing or office productivity, the Intel chip is noticeably faster, largely due to its higher boost clock of 4.50 GHz and the performance cores in its hybrid design.

The AMD Ryzen 5 6600U, despite losing every head-to-head test, does have a distinct role. Its wins are not in raw performance but in efficiency and integrated graphics. With a 15W TDP, it is designed to run cool and sip power, making it suitable for fanless or ultra-portable designs where battery life is paramount. The data does not directly compare battery life, but the TDP difference of 30W is a clear indicator of the intended use case. The AMD chip also features the Radeon 660M integrated graphics, while the Intel uses Iris Xe 80EU. The benchmark data provided does not include a direct comparison of these GPUs, so their relative performance cannot be quantified from this pack. The AMD's advantage is therefore not in CPU benchmark scores, but in the system-level characteristics of power consumption and the potential for a more capable integrated GPU, which is a qualitative distinction based on the hardware listed.

Architecture Differences

The two processors are built on fundamentally different architectural philosophies. The AMD Ryzen 5 6600U uses the Zen 3+ architecture, codenamed Rembrandt, and is manufactured on a 6nm process at TSMC. It has 6 cores and 12 threads, a configuration of uniform high-efficiency cores. The Intel Core i5-12500H, by contrast, uses the Alder Lake architecture, codenamed Alder Lake-H, and is built on Intel's 10nm process. It features a hybrid design with 12 cores and 16 threads, which implies a mix of performance (P-cores) and efficiency (E-cores). This is a critical difference: the Intel chip has double the core count and 4 more threads, which explains its massive lead in multi-threaded workloads. The base clocks also differ, with the AMD starting at 2.90 GHz and the Intel at 2.50 GHz, but both boost to the same 4.50 GHz. However, the Intel part's higher TDP of 45W allows it to sustain that boost clock across more cores for longer periods.

The cache hierarchies are also different. The AMD chip has 64 KB of L1 and 512 KB of L2 per core, with 16 MB of shared L3. The Intel part has 80 KB of L1 and 1.25 MB of L2 per core, with 18 MB of shared L3. The Intel chip has a larger cache at every level, which helps feed its higher core count and reduce memory latency. Memory support also differs: the AMD supports only DDR5, while the Intel supports both DDR4 and DDR5. The AMD has a specified memory bandwidth of 76.8 GB/s, while the Intel's is not listed in the data. Both use the same PCIe Gen 4 with 20 lanes, but they are on different sockets: AMD Socket FP7 versus Intel BGA 1744. The integrated graphics are also distinct: Radeon 660M on the AMD and Iris Xe 80EU on the Intel, with no benchmark data to compare them directly.

Head-to-Head Benchmarks

The head-to-head results are a clean sweep for the Intel Core i5-12500H, with the largest margins in multi-threaded and floating-point workloads. The most decisive victory is in Cinebench R23 multi-core, where the Intel's 19840 score is more than double the AMD's 9159.5, a delta of -53.8%. This is the single biggest gap in the entire comparison and highlights the impact of the Intel's 12 cores versus the AMD's 6. In Cinebench R15 multi-core, the Intel also wins decisively with a score of 1999 versus 1493, a 25.3% lead. These results indicate that for any professional rendering or video encoding task, the Intel processor is the clear choice.

The Intel's advantage extends to floating-point math, where it scores 52227 in the PassMark test against the AMD's 33991, a 34.9% lead. This is a significant margin that would benefit scientific computing and certain engineering applications. In integer math, the lead is smaller but still substantial at 13.9%, with the Intel scoring 71714 versus 61723. The Intel also wins in data compression by 20.5% (253431 vs 201364) and random string sorting by 24.4% (28099 vs 21241), indicating faster file archiving and database operations.

The single-threaded wins are less dramatic but consistent. In Cinebench R23 single-core, the Intel leads by 48% (2801 vs 1456.5), while in Cinebench R15 single-core, the lead is 17.4% (282 vs 233). The smallest margin in the entire set is in PassMark single-thread, where the Intel scores 3418 versus the AMD's 3132, an 8.4% lead. This shows that even in the most lightly-threaded tasks, the Intel part is faster, though the gap is much smaller than in multi-threaded workloads. The Intel also wins in data encryption by 13.3%, extended instructions by 10.8%, and physics by 19.0%, rounding out a comprehensive victory in every measured category.

The Verdict

The data is clear: for raw CPU performance, the Intel Core i5-12500H is the superior processor. It wins every single benchmark comparison, with particularly large margins in multi-threaded and floating-point workloads. Any user whose primary need is processing power—content creators, engineers, data analysts, or gamers who need a powerful CPU—should choose the Intel part based on this data alone. The 53.8% lead in Cinebench R23 multi-core and 34.9% lead in floating-point math are not marginal improvements; they represent a generational gap in capability.

The AMD Ryzen 5 6600U, however, is not without merit. Its 15W TDP, versus the Intel's 45W, positions it for a completely different segment of the laptop market. The data does not include battery life or sustained performance tests, but the TDP specification is a strong indicator that the AMD chip is intended for thinner, lighter, and more power-efficient systems. For users who prioritize portability and battery life over raw speed, the AMD chip is the appropriate choice. Its slightly higher average benchmark score of 22897 versus 22625 is a statistical curiosity but does not override the fact that the Intel wins every direct comparison. The verdict is simple: pick the Intel for maximum performance, and pick the AMD for a system designed around efficiency and likely longer battery life.
