AMD Ryzen 7 PRO 5755G vs Intel Core Ultra X7 358H Comparison

The AMD Ryzen 7 PRO 5755G and Intel Core Ultra X7 358H occupy different corners of the processor market, one a desktop part with a traditional layout and the other a mobile chip with a hybrid design. The benchmark data shows a clear split: Intel wins most computational tests outright, but AMD holds a single significant victory in integer math. The Core Ultra X7 358H posts a higher average benchmark score of 40967, though the Ryzen 7 PRO 5755G sits in the 90th percentile of all CPUs compared to the Intel part’s 87th percentile. This discrepancy stems from the fact that the AMD chip’s average is pulled up by its strong PassMark scores, while the Intel part’s average reflects a broader set of tests including Cinebench results where it excels. The following analysis breaks down where each processor demonstrates its strengths based on recorded measurements.

Where Each One Wins

The Intel Core Ultra X7 358H dominates the head-to-head matchup, winning 10 of the 11 comparative benchmarks. Its largest advantages appear in single-threaded workloads, floating-point mathematics, and physics simulations. The data shows Intel wins the PassMark single-thread test with a score of 4124 against AMD’s 3366, a delta of 18.4 percent. In floating-point math, the Intel part scores 103842 versus 50778, a massive 51.1 percent lead. The physics test shows Intel at 3021 against AMD’s 1022, a 66.2 percent gap. These results indicate the Intel chip is built for scenarios requiring high per-core performance and complex arithmetic, such as scientific computing, rendering, and simulation tasks.

The AMD Ryzen 7 PRO 5755G secures exactly one win, but it is a meaningful one. In PassMark integer math, AMD scores 90270 against Intel’s 83147, an 8.6 percent advantage. This test measures raw integer arithmetic throughput, which is relevant for database operations, compression algorithms, and general office productivity. The AMD processor also shows strength in data compression relative to its other scores, though it still loses to Intel in that specific test. For users running workloads that are heavily integer-bound and less dependent on floating-point or single-thread speed, the AMD part holds a niche advantage.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 PRO 5755G uses the Zen 3 architecture on a 7 nm process from TSMC, with a die size of 180 mm² and 10,700 million transistors. It has 8 cores and 16 threads, which means it relies on simultaneous multithreading to handle parallel workloads. The cache hierarchy is per-core: 64 KB of L1, 512 KB of L2, and a 16 MB shared L3 pool. The base clock is 3.80 GHz with a boost clock of 4.60 GHz, running at a 65 W TDP on AMD Socket AM4. It supports DDR4 memory in dual-channel configuration with a bandwidth of 51.2 GB/s and offers PCIe Gen 3 with 16 lanes. The integrated graphics are Radeon Vega 8.

The Intel Core Ultra X7 358H uses the Panther Lake codename and is manufactured on Intel’s 3 nm process. This is a mobile part with 16 cores and 16 threads, indicating a hybrid architecture without hyperthreading. The cache setup differs significantly: 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3. The base clock is much lower at 1.90 GHz, but the boost clock reaches 4.80 GHz. The TDP is 25 W, a fraction of the AMD part’s power envelope. It uses Intel BGA 2540, supports LPDDR5X memory with a bandwidth of 153.6 GB/s, and offers PCIe Gen 5 with 4 lanes. The integrated graphics are Arc B390. The release dates show a notable gap: AMD launched in September 2024, while Intel arrived in January 2026.

Head-to-Head Benchmarks

The most lopsided result in the dataset is the PassMark find prime numbers test. Intel scores 337 while AMD manages only 58, an 82.8 percent deficit for AMD. This test is highly sensitive to single-core integer throughput and branch prediction, and the Intel part’s higher boost clock and newer architecture clearly deliver in this specific workload. Similarly, the floating-point math test shows Intel at 103842 versus AMD’s 50778, a 51.1 percent gap, indicating superior SIMD execution or wider vector units on the Intel chip.

The physics test favors Intel heavily as well, with a score of 3021 against 1022, a 66.2 percent difference. This benchmark typically stresses multi-threaded performance and cache efficiency, where Intel’s 16 cores and larger L3 cache help. The multithread PassMark score shows Intel at 33802 versus AMD’s 23858, a 29.4 percent lead, confirming that Intel’s core count advantage translates into real parallel throughput gains. The data compression test shows Intel at 332508 versus AMD’s 295730, an 11.1 percent win, and the encryption test shows Intel at 26046 versus 19450, a 25.3 percent margin. Extended instructions, which measure SIMD and specialized instruction set usage, go to Intel by 24.9 percent with scores of 27274 against 20487.

Random string sorting favors Intel at 40357 versus 32771, an 18.8 percent difference. The single-thread results, listed twice in the data as PassMark single-thread and singlethread, both show Intel at 4124 against AMD’s 3366, an 18.4 percent margin. AMD’s only win comes in integer math, where it scores 90270 against Intel’s 83147. That 8.6 percent advantage stands out because it is the only test where AMD’s older Zen 3 design outpaces the newer Panther Lake part. It suggests AMD’s integer execution units are particularly efficient, even if they lag in other areas.
