The Verdict

The data points to a clear verdict for users who prioritize multi-threaded throughput: the AMD Ryzen 9 9950X is the stronger processor across nearly every measured workload. Its average benchmark score is 74,640, placing it in the 94th percentile of all CPUs, while the Intel Core 9 273PTE averages 31,143, in the 82nd percentile. The Ryzen 9 9950X sits among rivals like the AMD Ryzen 7 PRO 9745 (average 74,761, delta -0.2%), the AMD Ryzen AI 9 HX PRO 475 (average 74,496, delta 0.2%), and the Intel Core Ultra 9 285 (average 75,488, delta -1.1%). The Intel Core 9 273PTE, by contrast, aligns with the Intel Core i7-12700F (average 31,081, delta 0.2%) and the AMD Ryzen 9 8945HS (average 31,074, delta 0.2%).

The single Intel win in Cinebench R23 single-core indicates that the Intel part has a specific strength in lightly threaded, single-core rendering tasks as measured by that test. However, the AMD chip still wins the other single-core tests, including PassMark single-thread and Cinebench R15 single-core. The overall record shows that the Ryzen 9 9950X delivers a broad performance advantage, particularly in compression, encryption, extended instructions, and multi-threaded compute.

The power envelope differs substantially, with the Ryzen 9 9950X rated at 170 W TDP and the Intel Core 9 273PTE at 45 W TDP. The data shows the AMD part achieves its higher scores while consuming significantly more power, an important consideration for system design. The Intel part's lower TDP and lower scores indicate a trade-off between peak performance and power draw.

Where Each One Wins

The AMD Ryzen 9 9950X wins in multi-threaded compute, data compression, encryption, extended instructions, integer math, floating point math, prime number finding, random string sorting, physics, and most single-thread tests. Its 16-core, 32-thread configuration and 64 MB L3 cache give it a strong edge in rendering, scientific computing, and data processing workloads. The Cinebench R23 multi-core score of 40,924 demonstrates a 100.2% advantage over the Intel part, and the PassMark multithread score of 66,030 is 174.5% higher. The near-total sweep of the head-to-head benchmarks indicates that the Ryzen 9 9950X is the more capable processor for almost all measured tasks.

The Intel Core 9 273PTE wins in Cinebench R23 single-core only, with a score of 2,886. This suggests a specific advantage in workloads that stress a single core as measured by that benchmark. Its lower TDP of 45 W also positions it as a more power-efficient option, though the performance data shows it trails the AMD part significantly in multi-threaded tasks. The Intel part's support for both DDR4 and DDR5 memory provides flexibility in system configuration, and its 2 MB L2 per core is double that of the AMD part.

The data supports a simple split: the AMD Ryzen 9 9950X is the choice for maximum performance across a wide range of benchmarks, while the Intel Core 9 273PTE offers a single-core win in one test and a much lower power envelope. The Ryzen 9 9950X's percentile rank of 94 versus the Intel's 82, along with the average score difference, reinforces the AMD part's overall dominance in the recorded measurements.
