Analysis: AMD Ryzen 7 7700X3D vs Intel Core Ultra X7 358H
Head-to-Head Benchmarks
The database contains no direct head-to-head benchmark results for the AMD Ryzen 7 7700X3D versus the Intel Core Ultra X7 358H. The AMD processor has no recorded benchmark scores or average score, while the Intel part has a full suite of Cinebench and Passmark results. This makes a direct comparison of measured performance impossible from the recorded data alone.
What the data does show is that the Intel Core Ultra X7 358H holds an average benchmark score of 40,967 across all recorded tests. That places it at the 87th percentile among all CPUs in the database. The AMD Ryzen 7 7700X3D sits at the 50th percentile, but that figure is based on zero recorded scores, meaning it reflects a placeholder rather than real performance data.
For the Intel chip specifically, the Cinebench results show a multi-core score of 18,747 in Cinebench R23, a single-core score of 2,080 in the same test, and a Cinebench R20 multi-core score of 12,011. The Passmark suite shows a multithread score of 33,802, a single-thread score of 4,124, and a floating-point math score of 103,842.
The nearest rivals for the Intel chip in the database are all close matches. The AMD Ryzen AI 5 PRO 440 scores 41,208, which is 0.6% higher than the Intel Core Ultra X7 358H. The Intel Core Ultra 7 356H scores 41,215, also 0.6% higher. The AMD Ryzen AI 5 PRO 435G scores 40,718, which is 0.6% lower. The Intel Core Ultra 7 366H scores 41,263, which is 0.7% higher. These deltas show the X7 358H sits in a tightly packed performance cluster, with no rival more than 0.7% away in either direction.
Architecture Differences
The two processors come from different manufacturing processes and design philosophies. The AMD Ryzen 7 7700X3D uses a 5 nm process node fabricated by TSMC, while the Intel Core Ultra X7 358H uses a 3 nm node fabricated by Intel. The AMD chip is built on the Zen 4 architecture with the Raphael codename, part of the Ryzen 7 generation. The Intel chip uses the Panther Lake codename with the Panther Lake-H architecture, part of the Ultra X7 generation.
Transistor counts and die sizes differ significantly. The AMD processor has 11,270 million transistors on a 71 mm² die. The Intel processor has no recorded transistor count or die size in the database.
The core configurations are fundamentally different. The AMD Ryzen 7 7700X3D has 8 cores and 16 threads. The Intel Core Ultra X7 358H has 16 cores and 16 threads. This means the Intel chip has twice as many physical cores but the same thread count, indicating it does not use simultaneous multithreading.
Cache hierarchies diverge sharply. The AMD chip has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 96 MB of shared L3 cache. The Intel chip has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 18 MB of shared L3 cache. The AMD chip carries over five times the L3 cache of the Intel chip.
Memory support differs by platform. The AMD chip uses DDR5 memory with dual-channel support and 83.2 GB/s of memory bandwidth. The Intel chip uses LPDDR5X memory, also dual-channel, but with 153.6 GB/s of memory bandwidth, roughly 85% higher. The AMD chip supports ECC memory; the Intel chip does not.
PCIe connectivity also differs. The AMD chip provides Gen 5 with 24 lanes from the CPU. The Intel chip provides Gen 5 with only 4 lanes from the CPU. Integrated graphics differ as well: the AMD chip uses Radeon Graphics, while the Intel chip uses Arc B390.
Where Each One Wins
Based on the recorded data, the Intel Core Ultra X7 358H has clear advantages in several areas. Its 16-core configuration gives it a strong foundation for heavily threaded workloads. The Cinebench R23 multi-core score of 18,747 and Passmark multithread score of 33,802 both indicate solid parallel performance. The memory bandwidth of 153.6 GB/s is substantially higher than the AMD chip's 83.2 GB/s, which benefits memory-intensive tasks such as data compression and encryption workloads. The Passmark data compression score of 332,508 and data encryption score of 26,046 reflect that capability.
The AMD Ryzen 7 7700X3D, despite having no recorded benchmarks, shows structural advantages in the database. Its 96 MB of shared L3 cache is a substantial asset for workloads that repeatedly access the same data, such as gaming and certain database operations. The 24 PCIe Gen 5 lanes from the CPU provide more expansion headroom for high-bandwidth peripherals. The chip also supports ECC memory, which matters for users who require error-correcting memory in workstation or server-adjacent scenarios.
The Intel chip's higher boost clock of 4.80 GHz compared to the AMD chip's 4.50 GHz suggests a single-thread advantage, though no direct benchmark confirms this. The Intel chip's lower base clock of 1.90 GHz versus the AMD chip's 4.00 GHz indicates the Intel part is designed for burst performance rather than sustained all-core operation at high clocks.

The Verdict
The Intel Core Ultra X7 358H is the only one of the two processors with recorded benchmark data. Its average benchmark score of 40,967 places it at the 87th percentile among all CPUs, and its nearest rivals are all within 0.7% of its score. The Cinebench R23 multi-core score of 18,747 and Passmark multithread score of 33,802 provide concrete evidence of its parallel processing capability. The 153.6 GB/s memory bandwidth and 16-core configuration make it suited for mobile workloads that require high throughput in a 25-watt envelope.
The AMD Ryzen 7 7700X3D has no recorded benchmark scores, so its performance cannot be verified from the database. What the data does show is a desktop processor with 8 cores, 96 MB of L3 cache, 24 PCIe Gen 5 lanes, and ECC memory support. These features point toward a part designed for desktop builds where cache capacity and expansion options matter more than raw core count.
The choice between the two depends on platform and use case. The Intel chip is a mobile part on Intel BGA 2540 with a 25-watt TDP, suited for laptops and compact systems. The AMD chip is a desktop part on AMD Socket AM5 with a 120-watt TDP, suited for full desktop builds. Users who need a verified multi-threaded performer with high memory bandwidth should look at the Intel chip. Users who need a desktop processor with large cache, ECC support, and extensive PCIe connectivity should look at the AMD chip. The database cannot confirm the AMD chip's actual performance because no benchmark scores are recorded for it.
