AMD Ryzen 5 5500X3D vs Intel Core Ultra X7 358H Comparison

The AMD Ryzen 5 5500X3D and Intel Core Ultra X7 358H occupy different corners of the processor market, yet the benchmark data places them in direct competition. The Ryzen 5 5500X3D is a desktop part built on the Zen 3 architecture, while the Core Ultra X7 358H is a mobile processor using Intel’s Panther Lake design. Despite the Intel chip’s mobile orientation and lower thermal envelope, the recorded measurements show a decisive performance gap in its favor across every shared test.

Head-to-Head Benchmarks

The head-to-head results are unambiguous: the Intel Core Ultra X7 358H wins all 11 recorded comparisons. The largest margin appears in floating-point math, where the Intel part scores 103842 against the AMD chip’s 34511. That is a 66.8% deficit for the Ryzen 5 5500X3D, the most severe single-test difference in the dataset. The gap suggests the Intel processor’s wider execution resources or higher boost clock dominate workloads that rely on sustained arithmetic throughput.

Prime number finding shows the second-largest delta. The Core Ultra X7 358H records 337, while the Ryzen 5 5500X3D manages 170, a 49.6% shortfall. This test often scales with integer throughput and clock speed, and the Intel part’s 4.80 GHz boost clock versus the AMD chip’s 4.00 GHz helps explain the result. Data encryption follows a similar pattern: Intel scores 26046, AMD scores 13967, a 46.4% difference. Extended instructions also favor Intel heavily, 27274 versus 15925, a 41.6% gap.

Multithreaded performance tells the same story. The Core Ultra X7 358H posts 33802 in the PassMark multithread test, while the Ryzen 5 5500X3D reaches 20363, a 39.8% deficit. This is notable because the AMD chip has 12 threads from 6 cores, while the Intel part has 16 threads from 16 cores. The Intel processor’s core count advantage, combined with its higher boost clock, delivers a clear lead in parallel workloads. Random string sorting shows a 41.3% gap, with Intel at 40357 and AMD at 23675.

Single-thread performance is also decisively in Intel’s favor. The Core Ultra X7 358H scores 4124, while the Ryzen 5 5500X3D scores 2941, a 28.7% difference. This is a significant margin for single-core tasks such as legacy applications or lightly threaded games. Integer math shows a 27.8% gap, with Intel at 83147 and AMD at 60033. Data compression is closer in relative terms but still favors Intel, 332508 versus 230392, a 30.7% gap. Physics simulation shows the smallest margin, with Intel at 3021 and AMD at 2282, a 24.5% difference.

The average benchmark score confirms the overall picture. The Core Ultra X7 358H averages 40967 across all recorded tests, placing it in the 87th percentile of all CPUs. The Ryzen 5 5500X3D averages 37018, placing it in the 85th percentile. The Intel chip’s nearest rivals include the AMD Ryzen AI 5 PRO 440, which scores 41208, and the Intel Core Ultra 7 356H, which scores 41215. The Ryzen 5 5500X3D sits close to the AMD Ryzen 5 5600F, which averages 36945, and the Intel Core Ultra 5 225, which averages 36938. The data shows the Intel part operating roughly 10% higher in average score, a gap that appears consistently across individual workloads.

The Verdict

The data points to a straightforward choice for anyone who prioritizes raw performance. The Intel Core Ultra X7 358H wins every single benchmark in the head-to-head comparison, with margins ranging from 24.5% to 66.8%. Its 16 cores and 16 threads, paired with a 4.80 GHz boost clock, give it a commanding lead in both single-threaded and multi-threaded tasks. The Ryzen 5 5500X3D, with 6 cores, 12 threads, and a 4.00 GHz boost clock, cannot match that output in any recorded workload.

The Ryzen 5 5500X3D does offer a 96 MB shared L3 cache, which is the largest cache allocation in this comparison. That cache size may benefit certain cache-sensitive workloads, but the benchmark results do not show it translating into a win on any of the recorded tests. The AMD chip also supports ECC memory and uses the AM4 socket, which could matter for system compatibility, but those factors do not appear in the performance data.

The Intel part’s integrated Arc B390 graphics add functionality that the AMD chip lacks entirely, since the Ryzen 5 5500X3D has no integrated GPU. For a system without a discrete graphics card, that is a functional advantage. The Intel processor also uses a 25 W TDP, which is far lower than the AMD chip’s 105 W TDP, indicating significantly higher efficiency per watt in the recorded performance.

Users building a desktop system with an existing AM4 motherboard may prefer the Ryzen 5 5500X3D for platform continuity, but the performance data does not support choosing it for speed. The Core Ultra X7 358H is the faster processor in every measured category, and the margin is large in several tests. The verdict from the database is clear: the Intel part outperforms the AMD part across the board.

Specification Differences

The two processors differ in nearly every core specification. The AMD Ryzen 5 5500X3D uses 6 cores and 12 threads, while the Intel Core Ultra X7 358H uses 16 cores and 16 threads. Base clocks diverge sharply: the AMD chip runs at 3.00 GHz, the Intel chip at 1.90 GHz. Boost clocks reverse the order, with AMD at 4.00 GHz and Intel at 4.80 GHz.

Thermal design power presents a major contrast. The AMD processor is rated at 105 W, while the Intel processor is rated at 25 W. The socket types are incompatible: AMD uses Socket AM4, Intel uses BGA 2540. The AMD part is a desktop processor, while the Intel part is a mobile processor.

Memory support differs as well. The AMD chip supports DDR4 memory with dual-channel access and a bandwidth of 51.2 GB/s. The Intel chip supports LPDDR5X memory, also dual-channel, but with a bandwidth of 153.6 GB/s. ECC memory is supported by the AMD processor but not by the Intel processor. PCIe lanes also vary: AMD provides Gen 4 with 20 lanes, while Intel provides Gen 5 with 4 lanes from the CPU.

Cache hierarchies are structurally different. The AMD Ryzen 5 5500X3D has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 96 MB of shared L3 cache. The Intel Core Ultra X7 358H has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 18 MB of shared L3 cache. Neither processor has a listed vCache3d value.

Architecture Differences

The AMD Ryzen 5 5500X3D is built on the Zen 3 architecture with the codename Vermeer. It uses a 7 nm process node manufactured by TSMC, and the die size is recorded at 74 mm². The Intel Core Ultra X7 358H uses the Panther Lake codename with the Panther Lake-H generation designation. It is built on a 3 nm process node manufactured by Intel. The Intel part’s die size is not recorded in the database.

The AMD processor belongs to the 5000 series and is listed as a Ryzen 5 generation part. The Intel processor belongs to the Core Ultra Series 3 and is listed as an Ultra X7 generation part. The AMD chip has a locked multiplier, as does the Intel chip. Neither processor offers overclocking via an unlocked multiplier.

The Intel processor includes an integrated Arc B390 graphics unit, which is absent from the AMD part. The AMD processor supports ECC memory, which the Intel part does not. The release dates differ, with the AMD part released in 2025 and the Intel part in 2026. The process node gap, from 7 nm to 3 nm, reflects a generational difference in manufacturing technology, which likely contributes to the Intel part’s higher performance and lower TDP.
