Architecture Differences

The AMD Ryzen 7 7735H is built on the Zen 3+ architecture (codenamed Rembrandt-R) using a 6 nm process at TSMC. The Intel Core Ultra 5 225 uses the Arrow Lake architecture (codenamed Arrow Lake-S) on a 3 nm node, also from TSMC. This process advantage is substantial: the Intel chip packs 17,800 million transistors on a 243 mm² die, while the AMD die is 208 mm² with transistor count not listed.

Core configurations differ fundamentally. The AMD part has 8 cores and 16 threads, relying on simultaneous multithreading. The Intel chip has 10 cores and 10 threads, with no multithreading — a pure physical-core design. This explains why the Intel part wins multi-core tests despite having fewer threads.

Cache hierarchies are also distinct. The AMD Ryzen 7 7735H has 64 KB L1 and 512 KB L2 per core, plus 16 MB shared L3. The Intel Core Ultra 5 225 has 192 KB L1 and 3 MB L2 per core, plus 20 MB shared L3. The Intel chip’s larger per-core L2 is 6× that of the AMD part.

Both support DDR5 memory in dual-channel mode, but the Intel chip’s memory bandwidth is rated at 102.4 GB/s versus 76.8 GB/s for the AMD part. The AMD chip supports ECC memory; the Intel chip does not. PCIe generations differ: AMD uses Gen 4 with 20 lanes, Intel uses Gen 5 with 20 lanes.

The integrated graphics differ sharply. AMD pairs the Radeon 680M, while Intel uses Arc Xe-LPG Graphics with 16 EU. The AMD part is a mobile chip (Socket FP7), while the Intel part is a desktop chip (Socket 1851). The Intel chip was released on 2025-01-06; the AMD chip on 2023-03-31.

Head-to-Head Benchmarks

The Intel Core Ultra 5 225 dominates the Cinebench suite. In Cinebench R15 multi-core, it scores 2609 versus 1825 for the AMD part — a 30% lead. Single-core R15 shows a 33.2% gap (368 vs 246). The R23 results are even more lopsided: the Intel chip scores 25891 in multi-core versus 10920 (57.8% ahead), and 3655 in single-core versus 1536 (58% ahead). These deltas indicate the Intel architecture’s per-core efficiency is dramatically higher.

PassMark multithread reinforces the trend: Intel scores 30459 against AMD’s 23765, a 22% win. PassMark physics also favors Intel heavily — 2342 versus 1056, a 54.9% gap. Floating-point math shows a 46.5% Intel advantage (92038 vs 49260). Extended instructions go Intel’s way by 21.9% (27162 vs 21214). Random string sorting is closer, with Intel ahead 36590 vs 31676 (13.4%). Data encryption favors Intel by 14.8% (22285 vs 18990).

The AMD Ryzen 7 7735H’s wins are narrow or situational. Data compression is essentially a tie: AMD scores 303502 versus Intel’s 302811, a 0.2% margin. Integer math is the one decisive AMD victory — 86788 versus 65345, a 32.8% advantage. This suggests AMD’s integer execution pipeline is strong, but it doesn’t translate into broader wins.

Single-thread PassMark confirms the Intel chip’s superiority: 4412 versus 3288, a 25.5% lead. The find-prime-numbers test is brutal for AMD: 358 versus 59, an 83.5% Intel win — the largest delta in the entire set. This test highlights the Intel chip’s raw integer throughput on a per-core basis, even though AMD wins the aggregate integer math test.

The Verdict

The data points to a clear winner for raw performance: the Intel Core Ultra 5 225. It wins 13 of 15 benchmarks, with margins ranging from 0.2% to 83.5%. Its Cinebench R23 multi-core score of 25891 is more than double the AMD part’s 10920. The single-core gap of 58% in R23 is decisive for everyday responsiveness and lightly threaded workloads.

The AMD Ryzen 7 7735H is not without merit. Its 32.8% win in integer math and 0.2% edge in data compression show specific strengths. The 85th percentile ranking for both chips means they are broadly comparable in the overall CPU landscape, with average scores of 37161 and 36938 — a mere 0.6% difference. But the benchmark-by-benchmark breakdown favors Intel overwhelmingly.

Who should pick the AMD Ryzen 7 7735H? Users prioritizing mobile platforms, ECC memory support, or lower power draw (35 W TDP vs 65 W). Its Radeon 680M integrated graphics could also matter for compact systems. However, the data does not support choosing it for performance.

Who should pick the Intel Core Ultra 5 225? Anyone needing the highest multi-threaded throughput, the best single-core speed, or the most consistent wins across diverse workloads. Its 10 physical cores, larger caches, and 3 nm process deliver measurable advantages. The 102.4 GB/s memory bandwidth and PCIe Gen 5 support are additional structural benefits. The Intel chip is the data-driven choice for desktop performance.
