AMD Ryzen 5 PRO 6650U vs Intel Core i5-12500H Comparison

The Intel Core i5-12500H and AMD Ryzen 5 PRO 6650U represent two different philosophies for mobile computing: one is a performance-oriented H-series part with a high power envelope, while the other is a power-efficient PRO series chip designed for business ultrathins. The benchmark database shows a clear and consistent performance hierarchy between the two, with the Intel part winning every single head-to-head comparison. However, the recorded data also reveals significant architectural and efficiency trade-offs that define where each processor is the appropriate choice. This analysis breaks down the measured performance, the underlying design differences, and the practical use cases derived from the data.

Head-to-Head Benchmarks

The head-to-head results are unequivocal: the Intel Core i5-12500H wins all 15 recorded benchmark comparisons, with no wins for the AMD Ryzen 5 PRO 6650U. The scope of the victory varies dramatically by workload, from a modest single-thread margin to a dominant multi-core advantage.

The largest gap appears in Cinebench R23 multi-core, where the Intel part scores 19840 against AMD's 8854, a 124.1% lead. This is a massive difference, indicating that in heavily threaded rendering workloads, the Intel processor delivers more than double the performance. The Cinebench R23 single-core test also shows a substantial edge, with Intel at 2801 versus AMD's 1463, a 91.5% advantage. This is notable because single-core performance is often less dependent on core count and more on IPC and clock speed, yet the Intel chip still wins decisively.

Other large deltas are found in floating-point math, where Intel scores 52227 versus AMD's 32571, a 60.3% lead, and in random string sorting, where Intel scores 28099 versus 20299, a 38.4% advantage. Data compression also favors Intel significantly, with a score of 253431 versus 190180, a 33.3% lead. These results suggest that the Intel processor's hybrid architecture and higher thread count provide a substantial boost in parallel and memory-intensive tasks.

In Cinebench R15, the multi-core test shows Intel at 1999 versus AMD at 1459.5, a 37% lead, while the single-core test shows a 21.3% advantage (282 vs 232.5). The PassMark multi-thread score gives Intel a 25.5% lead (20625 vs 16429), and the extended instructions test shows a 22.1% advantage (14965 vs 12261). Physics simulation yields a 21.6% lead for Intel (1018 vs 837), while data encryption shows a 21.3% advantage (14749 vs 12159). Integer math is closer, with Intel at 71714 versus 60045, a 19.4% lead. The smallest margins are in prime number finding, where Intel leads by only 9.6% (57 vs 52), and in PassMark single-thread tests, where Intel leads by 8.5% (3418 vs 3149). Even in the closest contests, the Intel processor maintains a clear, measurable advantage.

Architecture Differences

The fundamental architectural split between these two processors explains the benchmark results. The Intel Core i5-12500H is built on Alder Lake-H architecture, using a 10 nm process from Intel's own foundry. It features 12 cores and 16 threads, a configuration that leverages Intel's hybrid design with performance and efficiency cores. The base clock is 2.50 GHz, boosting to 4.50 GHz, and it has a 45W TDP. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache. The die size is 217 mm².

The AMD Ryzen 5 PRO 6650U is based on Zen 3+ architecture, codenamed Rembrandt, fabricated on a 6 nm process by TSMC. It is a more conventional 6-core, 12-thread design with a base clock of 2.90 GHz and a boost clock of 4.50 GHz. Its TDP is dramatically lower at 15W, reflecting its ultra-mobile focus. The cache layout is smaller: 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The die size is 208 mm², slightly smaller than Intel's.

Memory support differentiates the two as well. The Intel chip supports both DDR4 and DDR5, while the AMD chip supports only DDR5. Both use dual-channel memory buses, but the database lists a specific memory bandwidth of 76.8 GB/s for the AMD part, a figure not provided for the Intel chip. Both processors offer PCIe Gen 4 with 20 lanes from the CPU, but they use different sockets: Intel uses BGA 1744, while AMD uses Socket FP7. The integrated graphics also differ: Intel has Iris Xe 80EU, while AMD has Radeon 660M. Neither supports ECC memory, and both have locked multipliers.

The production status for both is active, and the AMD part has a release date of April 2022, while the Intel part's release date is not listed. The process node difference (10 nm for Intel vs 6 nm for AMD) suggests AMD's design is more power-efficient per transistor, but the Intel chip's higher core count and higher TDP allow it to deliver far more raw performance, as evidenced by the benchmark data.

Where Each One Wins

Given the benchmark results, the Intel Core i5-12500H is the clear winner in almost every compute-intensive scenario. Its 124.1% lead in Cinebench R23 multi-core makes it the superior choice for video rendering, 3D modeling, and other workloads that scale with thread count. The 60.3% lead in floating-point math indicates strength in scientific computing and simulations. The 33.3% advantage in data compression and 21.3% lead in encryption suggest better performance in file archiving and security-related tasks. For users who prioritize raw throughput in multi-threaded applications, the Intel chip is the obvious selection based on the data.

The AMD Ryzen 5 PRO 6650U, despite losing every benchmark, has a distinct advantage not captured in the raw scores: its 15W TDP versus Intel's 45W TDP. This makes it the better choice for scenarios where power efficiency is paramount, such as thin-and-light laptops where battery life is critical and where passive cooling or low-noise operation is desired. The 6 nm process and lower core count contribute to this efficiency. While the database does not provide direct battery life or power consumption measurements, the TDP figures alone indicate that the AMD chip will generate significantly less heat and consume less energy under load.

For single-threaded tasks, the Intel chip still wins by 8.5% in PassMark and 91.5% in Cinebench R23 single-core, so the AMD chip does not offer a single-thread advantage. However, in a thermally constrained chassis, the AMD chip may sustain its boost clocks longer than the Intel chip would under the same cooling solution, though this is not directly measurable from the provided data. The AMD chip's smaller die size and lower power draw also make it easier to integrate into compact designs.

In summary, the Intel Core i5-12500H is for users who need maximum performance and are willing to accept higher power consumption, typically in larger laptops with robust cooling. The AMD Ryzen 5 PRO 6650U is for users who prioritize portability and efficiency, where the performance deltas are acceptable trade-offs for a lighter, cooler, and longer-lasting system.

The data shows that the Intel part offers more cores, more threads, a larger cache hierarchy, and broader memory compatibility, but at the cost of a much higher TDP. The AMD part is built on a more advanced process node, which likely contributes to its lower power draw, though the benchmark scores confirm that this efficiency comes with a significant performance penalty in almost every measured workload.
