Where Each One Wins

The data does not split the workload categories evenly. The AMD Ryzen 9 9900X3D wins every shared test, so the analysis must focus on the magnitude of each win and what it implies for specific use cases.

For rendering and content creation, the AMD Ryzen 9 9900X3D is the clear choice. The consistent 52.6% lead across all three Cinebench versions, in both single-core and multi-core modes, indicates that the AMD part delivers substantially higher throughput in CPU-bound rendering tasks. The cinebench_r23_multicore score of 47737 places it well ahead of the Intel Core 9 273PE's 31288.

For data compression and encryption workloads, the AMD part again dominates. The passmark_data_compression score of 685074 versus 405885 (68.8% delta) and passmark_data_encryption score of 33282 versus 22719 (46.5% delta) show that the Zen 5 architecture handles these tasks with significantly more efficiency. The passmark_random_string_sorting result (71864 versus 45098, a 59.4% delta) further supports this pattern.

For scientific and mathematical computing, the AMD Ryzen 9 9900X3D shows its largest margins. The passmark_find_prime_numbers result (544 versus 203, a 168% delta) and passmark_extended_instructions result (55426 versus 24630, a 125% delta) suggest that workloads involving prime number generation, extended instruction sets, and similar computational patterns benefit greatly from the AMD part's design.

For general single-threaded responsiveness, the AMD Ryzen 9 9900X3D leads by 27.3% in both passmark_single_thread and passmark_singlethread (4646 versus 3650). The 3dmark results for the AMD part (single-thread score of 1269, 2-thread score of 2512, 4-thread score of 4885, 8-thread score of 9002, 16-thread score of 12490, and max-thread score of 13795) were not directly compared against the Intel part, but the available head-to-head data shows no category where the Intel Core 9 273PE takes a win.

The closest contest, passmark_floating_point_math at a 10.9% delta, still favors the AMD part. This suggests that even in the Intel Core 9 273PE's most competitive category, it cannot match the AMD Ryzen 9 9900X3D.

Specification Differences

Both processors share the same core and thread counts: 12 cores and 24 threads. The similarities end there. The AMD Ryzen 9 9900X3D has a base clock of 4.40 GHz and a boost clock of 5.50 GHz. The Intel Core 9 273PE has a base clock of 2.30 GHz and a boost clock of 5.70 GHz, meaning the Intel part boosts higher but has a much lower base clock.

Thermal design power differs significantly. The AMD Ryzen 9 9900X3D has a TDP of 120 watts, while the Intel Core 9 273PE has a TDP of 65 watts. The Intel part draws substantially less power under its rated design envelope.

Architecture Differences

The AMD Ryzen 9 9900X3D belongs to the 9000 series and uses the Zen 5 architecture under the Granite Ridge codename. It is built on a 4 nm process at TSMC and contains 16,630 million transistors across a die size of 2x 70.6 mm². The generation is listed as Ryzen 9 (Zen 5 (Granite Ridge)).

The Intel Core 9 273PE uses the Bartlett Lake codename and is listed as Core 9 (Bartlett Lake). It is built on a 10 nm process at Intel. No transistor count or die size is recorded in the database for the Intel part. The architecture field for the Intel part is not specified in the data.

The process node difference is substantial: 4 nm for AMD versus 10 nm for Intel. This explains, in part, the performance differences observed in the benchmarks. The AMD part's larger L3 cache (128 MB versus 36 MB) is a defining architectural feature, and it corresponds directly to the large margins seen in cache-sensitive workloads like passmark_find_prime_numbers and passmark_extended_instructions.

Both processors use 12 cores and 24 threads, but the base clock difference (4.40 GHz for AMD versus 2.30 GHz for Intel) means the AMD part starts from a much higher frequency floor. The Intel part's boost clock of 5.70 GHz is 0.20 GHz higher than the AMD part's 5.50 GHz, but the benchmark data shows that this boost advantage does not translate into winning results in any recorded test.

Memory architecture differs in flexibility: the Intel Core 9 273PE supports both DDR4 and DDR5, while the AMD Ryzen 9 9900X3D is DDR5-only. Both have identical peak memory bandwidth of 89.6 GB/s and dual-channel buses. The AMD part's PCIe implementation offers more lanes (24 versus 16) at the same Gen 5 standard.

The integrated graphics solutions differ: Radeon Graphics on the AMD side versus UHD Graphics 730 on the Intel side. The unlocked multiplier on the AMD Ryzen 9 9900X3D also distinguishes it from the locked Intel Core 9 273PE, which is a relevant factor for overclocking considerations, though the benchmark data does not include any overclocked results.

The Verdict

The recorded data supports a direct verdict: the AMD Ryzen 9 9900X3D is the faster processor in every shared benchmark against the Intel Core 9 273PE. The 17-0 head-to-head record, combined with a 52.6% average delta across Cinebench tests and leads ranging from 10.9% to 168% in PassMark subtests, leaves no ambiguity.

Users prioritizing multi-threaded rendering, data compression, encryption, or mathematical computation should select the AMD Ryzen 9 9900X3D based on the available data. Its 128 MB L3 cache and 4 nm process node are the most likely contributors to its dominance in cache-heavy and compute-heavy workloads. The consistent 52.6% Cinebench lead across all versions and thread counts indicates that the advantage is structural, not workload-specific.

The Intel Core 9 273PE does have attributes worth noting. Its 65 watt TDP is lower than the AMD part's 120 watt TDP, making it the more power-efficient choice on paper. It also supports both DDR4 and DDR5 memory, offering more platform flexibility. Its boost clock of 5.70 GHz is higher than the AMD part's 5.50 GHz. However, none of these attributes produce a winning benchmark result in the recorded data. The closest the Intel part comes is in passmark_floating_point_math, where it trails by 10.9%.

The aggregate standings place both processors near each other in the overall distribution: the AMD Ryzen 9 9900X3D at the 91st percentile with an average score of 54762, and the Intel Core 9 273PE at the 90th percentile with an average score of 49845. But the head-to-head measurements show that within this shared test set, the AMD part holds an unambiguous performance lead. The data indicates that the AMD Ryzen 9 9900X3D is the stronger choice for any workload represented in these benchmarks.
