Both run dual-channel memory with a recorded bandwidth of 89.6 GB/s. The integrated graphics differ: the AMD chip uses Radeon Graphics, and the Intel chip uses UHD Graphics 730.

The AMD processor uses AMD Socket AM5, while the Intel processor uses Intel Socket 1700. The AMD chip has an unlocked multiplier, and the Intel chip does not. The production status for both is Active. The AMD part was released on 2025-01-05, and the Intel part on 2026-03-08. The AMD part has a launch MSRP of $599, and the Intel part has a launch MSRP of $384.

Head-to-Head Benchmarks

The recorded head-to-head data shows the AMD Ryzen 9 9900X3D winning all 17 benchmark comparisons. The Intel Core 7 253PE does not win a single test in the database.

In Cinebench R23 multicore, the AMD scores 47737 against 24880 for Intel, a delta of 91.9%. The Cinebench R23 single-core test shows AMD at 6739 versus 3512, also a 91.9% delta. The Cinebench R20 multicore result is 20049 for AMD and 10449 for Intel, again a 91.9% delta. Cinebench R20 single-core is 2830 versus 1475, a 91.9% delta. Cinebench R15 multicore is 4811 versus 2507, and R15 single-core is 679 versus 354, both at a 91.9% delta.

PassMark results follow a similar pattern but with varying margins. The largest delta is in passmark_find_prime_numbers, where AMD scores 544 against 138, a 294.2% difference. passmark_physics shows AMD at 5340 and Intel at 1845, a 189.4% delta. passmark_extended_instructions has AMD at 55426 and Intel at 21806, a 154.2% delta. passmark_random_string_sorting is 71864 versus 32777, a 119.3% delta. passmark_data_compression shows 685074 versus 339133, a 102% delta. passmark_multithread is 56154 versus 29271, a 91.8% delta. passmark_data_encryption is 33282 versus 18385, an 81% delta. passmark_integer_math is 179727 versus 114158, a 57.4% delta. passmark_floating_point_math is 119622 versus 80870, a 47.9% delta. The smallest delta is in passmark_single_thread, where AMD scores 4646 against 3955, a 17.5% delta.

The single-thread delta of 17.5% is the narrowest margin in the dataset. This indicates that while the AMD chip dominates in multithreaded and specialized workloads, the per-thread advantage is comparatively smaller against this Intel part. The average benchmark score reflects the overall gap: 54762 for AMD versus 40557 for Intel. The AMD chip sits at the 91st percentile among all CPUs, while the Intel chip sits at the 87th percentile.

The Verdict

The benchmark data shows a decisive performance advantage for the AMD Ryzen 9 9900X3D across every recorded test. The AMD chip wins all 17 head-to-head comparisons, with deltas ranging from 17.5% in passmark_single_thread to 294.2% in passmark_find_prime_numbers. The average benchmark score of 54762 versus 40557 places the AMD part clearly ahead in the database's aggregate ranking.

The Intel Core 7 253PE does have recorded advantages in the specification table. It supports DDR4 in addition to DDR5, which can matter for platform flexibility. It has a lower TDP of 65 versus 120, which indicates a lower power envelope. It also has a lower launch MSRP of $384 versus $599. However, none of these specification advantages translate into a benchmark win in the recorded data.

The Intel chip's nearest rivals in the database are the Intel Core 5 223PE with an average score of 40585 and a delta of -0.1%, the Intel Core Ultra X7 368H with 40518 and a delta of 0.1%, the Intel Xeon 6357P with 40630 and a delta of -0.2%, and the AMD Ryzen 9 7940H with 40431 and a delta of 0.3%. These are close competitors, all within a fraction of a percent. The AMD Ryzen 9 9900X3D's nearest rivals are the Intel Core Ultra 5 245KF with 55093 and a delta of -0.6%, the Intel Core Ultra 5 245K with 54053 and a delta of 1.3%, the Intel Xeon 6505P with 53701 and a delta of 2%, and the Intel Core i7-14700F with 53620 and a delta of 2.1%. The AMD part sits in a different performance tier than the Intel Core 7 253PE.

The data indicates that the AMD Ryzen 9 9900X3D is the stronger performer in every measured workload. The Intel Core 7 253PE offers a lower power target and broader memory compatibility, but the recorded benchmarks do not show any workload where it takes the lead.

Where Each One Wins

The AMD Ryzen 9 9900X3D wins in every recorded benchmark category. The largest advantages appear in prime number finding, physics simulation, and extended instruction workloads. The passmark_find_prime_numbers test shows a 294.2% delta, which is the largest single margin in the dataset. passmark_physics shows a 189.4% delta, and passmark_extended_instructions shows a 154.2% delta. These results point to strong integer and specialized instruction performance for the Zen 5 architecture.

The AMD chip also leads heavily in data compression and random string sorting, with deltas of 102% and 119.3% respectively. Multithreaded workloads show a consistent 91.8% to 91.9% delta across Cinebench R15, R20, R23, and PassMark multithread. The smallest margin is in single-thread performance, where the AMD part leads by 17.5% in passmark_single_thread. This suggests that the Intel Core 7 253PE is comparatively closer in lightly threaded tasks, though it still trails in the recorded data.

The Intel Core 7 253PE does not win any benchmark in the database. Its recorded strengths are specification-based rather than performance-based. It has a lower TDP of 65, which may suit systems with stricter cooling or power limits. It supports DDR4 and DDR5, allowing the use of either memory type. It also has a lower launch MSRP of $384. For workloads that are not captured in the recorded benchmark set, these attributes could be relevant, but within the measured data, the AMD Ryzen 9 9900X3D holds every performance win.
