AMD Ryzen 9 9900X3D vs Intel Core 7 350 Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep in the head-to-head comparison. The AMD Ryzen 9 9900X3D wins all 17 benchmark comparisons with no wins for the Intel Core 7 350. The scale of the advantage varies dramatically by workload type, from a modest 13.3% lead in single-threaded tests to a massive 494.5% lead in multi-threaded rendering.

Starting with the Cinebench suite, the AMD processor delivers its largest margin in Cinebench R23 multicore with a score of 47737 against 8030, a 494.5% difference. This is the single biggest gap in the entire dataset. The R20 multicore test shows a 273.1% advantage with scores of 20049 versus 5373, while R15 multicore shows a 294.3% lead with 4811 against 1220. Single-core Cinebench results also favor AMD substantially, with R23 single-core showing a 229.4% lead (6739 versus 2046), R20 single-core at 273.4% (2830 versus 758), and R15 single-core at 132.5% (679 versus 292). These single-core gaps are notable because they indicate the AMD architecture has a significant per-thread performance advantage, not just a core-count advantage.

The Passmark suite reveals where the AMD part excels most. Integer math shows a 432.8% lead (179727 versus 33734), while finding prime numbers shows a 408.4% advantage (544 versus 107). Data compression delivers a 378.7% lead (685074 versus 143123), and extended instructions show a 360.2% gap (55426 versus 12045). Physics tests show a 355.2% advantage (5340 versus 1173), random string sorting a 316.9% lead (71864 versus 17238), and multithread performance a 270.2% gap (56154 versus 15170). Floating point math shows a 179.4% lead (119622 versus 42809), and data encryption a 204.4% advantage (33282 versus 10933).

The narrowest margin appears in Passmark single-threaded performance. The AMD chip scores 4646 against 4100, a 13.3% lead. This is the only benchmark category where the Intel processor comes within a close range. The single-thread result is the same for both the passmark_single_thread and passmark_singlethread entries in the database.

The overall average benchmark scores reflect this disparity. The AMD Ryzen 9 9900X3D has an average benchmark score of 54762, placing it at the 91st percentile of all CPUs. The Intel Core 7 350 has an average score of 17779, placing it at the 71st percentile. The AMD chip's nearest rivals in the database include the Intel Core Ultra 5 245KF with an average score of 55093 and a delta of -0.6%, the Intel Core Ultra 5 245K at 54053 with a delta of 1.3%, the Intel Xeon 6505P at 53701 with a delta of 2%, and the Intel Core i7-14700F at 53620 with a delta of 2.1%. The Intel Core 7 350's nearest rivals include the Intel Core 5 221TE at 17860 with a delta of -0.5%, the AMD EPYC 9374F at 17693 with a delta of 0.5%, the AMD Ryzen 5 3600XT at 17891 with a delta of -0.6%, and the Intel Core 5 120U at 17898 with a delta of -0.7%.

The Verdict

The benchmark data presents a straightforward comparison. The AMD Ryzen 9 9900X3D outperforms the Intel Core 7 350 in every recorded test. Anyone requiring maximum multi-core throughput should select the AMD part based on the 494.5% lead in Cinebench R23 multicore and the 432.8% lead in integer math. The AMD processor also holds the edge in single-threaded work with a 13.3% lead in Passmark and a 229.4% lead in Cinebench R23 single-core, so even lightly threaded applications run faster on the AMD chip.

The Intel Core 7 350 occupies a different segment entirely. Its 15 TDP, mobile socket, and 6-core design place it in a lower power envelope. The data shows no scenario where the Intel part wins, but the comparison is between a desktop flagship-class processor and a mobile-oriented chip. The Intel Core 7 350's average benchmark score of 17779 aligns it with processors like the AMD Ryzen 5 3600XT and the Intel Core 5 120U, which are its nearest rivals according to the database. The AMD Ryzen 9 9900X3D instead competes with the Intel Core Ultra 5 245KF and the Intel Core i7-14700F. These two processors do not actually compete in the same performance tier, and the benchmark database confirms this through the nearest rival groupings.

Where Each One Wins

The AMD Ryzen 9 9900X3D wins in every recorded benchmark category. The strongest wins are in multi-threaded workloads: Cinebench R23 multicore at 494.5% ahead, integer math at 432.8%, find prime numbers at 408.4%, data compression at 378.7%, and extended instructions at 360.2%. These results indicate workloads like 3D rendering, video encoding, scientific computation, and data processing will see the largest relative gains on the AMD platform.

The AMD part also dominates in physics simulation at 355.2% ahead, random string sorting at 316.9%, and Cinebench R15 multicore at 294.3%. The Cinebench R20 multicore result shows a 273.1% lead, and Passmark multithread shows a 270.2% lead. Data encryption shows a 204.4% advantage, floating point math a 179.4% lead, and Cinebench R15 single-core a 132.5% lead. Single-threaded Passmark performance shows the smallest gap at 13.3%, but the AMD chip still wins.

The Intel Core 7 350 has no benchmark wins in the recorded data. Its closest performance to the AMD part is in Passmark single-threaded tests, where it trails by only 13.3%. The low TDP of 15 and mobile socket suggest the Intel part is designed for power-constrained mobile systems, while the AMD part targets high-performance desktop builds. The single-channel memory bus at 59.7 GB/s and 6 PCIe Gen 4 lanes further indicate a mobile-oriented design with limited expansion capability.

For use cases requiring maximum compute throughput, desktop expansion, ECC memory support, and high-bandwidth dual-channel memory, the AMD Ryzen 9 9900X3D is the clear choice from the data. For ultra-low-power mobile systems where the 15 TDP and integrated Intel Xe3 Graphics with 2 Xe cores are priorities, the Intel Core 7 350 fits that niche, though it sacrifices performance across all recorded benchmarks to do so.
