AMD Ryzen 7 6800HS vs Intel Core Ultra 5 225H Comparison

The benchmark data presents a clear generational clash between Intel's Core Ultra 5 225H and AMD's Ryzen 7 6800HS. The Intel part, built on a newer process and architecture, dominates the majority of recorded tests, while the AMD chip secures a narrow but notable victory in specific integer and compression workloads. The overall average benchmark scores are remarkably close, with the AMD Ryzen 7 6800HS posting an average of 32354 against the Intel's 31508, yet the head-to-head results tell a story of distinct performance profiles.

Head-to-Head Benchmarks

The Intel Core Ultra 5 225H wins 15 of the 17 recorded head-to-head comparisons, and the magnitude of its victories is often substantial. In single-threaded workloads, the gap is pronounced. The Geekbench single-core result shows Intel scoring 2151 against AMD's 1652, a 30.2% advantage. This trend continues in Cinebench R23 single-core, where the Intel chip scores 1969 compared to 1455, representing a 35.3% lead. The PassMark single-thread test reinforces this picture, with Intel at 4258 and AMD at 3184, a 33.7% difference.

Multi-core performance also favors Intel, though the deltas are smaller but still significant. In Cinebench R23 multi-core, the Intel Core Ultra 5 225H scores 14629.5 versus AMD's 11992, a 22% lead. The Geekbench multi-core result shows a 21.1% advantage for Intel (11526 vs. 9515). Cinebench R15 multi-core and single-core tests both go to Intel, with leads of 20.7% and 23.3% respectively.

The most extreme disparity appears in the PassMark find prime numbers test. Here, the Intel chip scores 220, while the AMD Ryzen 7 6800HS manages only 56. This is a 292.9% difference, the largest of any recorded benchmark. Similarly, PassMark floating point math shows Intel at 86540 against AMD's 47533, an 82.1% lead. PassMark physics also heavily favors Intel, with a score of 1877 versus 1009, a 86% difference.

The AMD Ryzen 7 6800HS secures its two wins in specific workloads. In PassMark data compression, AMD scores 292698, edging out Intel's 283451, a 3.2% margin. The other win comes in PassMark integer math, where AMD scores 84228 against Intel's 68520, an 18.6% lead. These are notable results, but they are isolated within a broader set of benchmarks where Intel consistently holds the upper hand.

Other Intel wins include PassMark data encryption (21428 vs. 18104, 18.4% lead), extended instructions (21915 vs. 20114, 9% lead), multithread (28119 vs. 22801, 23.3% lead), and random string sorting (33654 vs. 30266, 11.2% lead).

Architecture Differences

The two processors are built on fundamentally different architectures and manufacturing processes. The Intel Core Ultra 5 225H is based on the Arrow Lake architecture, specifically Arrow Lake-H, and is manufactured on a 3 nm process at TSMC. It features 14 cores and 14 threads. Its base clock is 1.70 GHz with a boost clock of 4.90 GHz, and it has a TDP of 28 watts. The cache hierarchy consists of 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3 cache.

In contrast, the AMD Ryzen 7 6800HS uses the Zen 3+ architecture, codenamed Rembrandt, and is built on a 6 nm process, also at TSMC. It has 8 cores and 16 threads, with a base clock of 3.20 GHz and a boost clock of 4.70 GHz. The TDP is higher at 35 watts. AMD's cache layout is different: 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The AMD die is listed at 208 mm², while no die size is recorded for the Intel part.

These architectural differences directly explain the benchmark outcomes. The Intel chip's higher boost clock and newer process contribute to its substantial single-threaded advantages. The AMD chip's higher base clock and simultaneous multithreading (SMT) allow it to field 16 threads from 8 cores, yet it still loses in multi-threaded tests. The Intel part with 14 physical cores and 14 threads, lacking SMT, still manages to outperform the AMD part in most multi-threaded workloads.

Memory support also differs. The Intel Core Ultra 5 225H supports DDR5 and LPDDR5X in a dual-channel configuration, with a recorded memory bandwidth of 102.4 GB/s. The AMD Ryzen 7 6800HS supports DDR5 in a dual-channel configuration, but its memory bandwidth is lower at 76.8 GB/s. This bandwidth difference may contribute to Intel's performance in memory-sensitive workloads.

PCI Express capabilities diverge as well. The Intel part offers Gen 5 with 8 lanes (CPU only), while the AMD part provides Gen 4 with 20 lanes (CPU only). Integrated graphics differ, with Intel featuring Arc Graphics 130T and AMD featuring Radeon 680M.

Where Each One Wins

The Intel Core Ultra 5 225H is the clear choice for workloads that demand high single-threaded performance. Its 35.3% lead in Cinebench R23 single-core and 30.2% lead in Geekbench single-core indicate a strong advantage in applications that rely on per-core speed, such as everyday productivity, web browsing, and lightly threaded applications. The Intel part also excels in floating-point math, with an 82.1% lead, and physics calculations, with an 86% lead, making it suitable for scientific simulations and physics-based workloads. Its 292.9% lead in find prime numbers points to a massive advantage in integer-heavy computational loops.

The AMD Ryzen 7 6800HS has a specific, narrow niche. Its 18.6% lead in PassMark integer math suggests it handles certain integer-intensive algorithms more efficiently. The 3.2% lead in data compression indicates an edge in archiving and compression tasks. These wins are real but limited in scope. For users whose primary tasks are compression and integer math, the AMD part offers a measurable benefit.

For all other recorded benchmark categories, including multi-threaded rendering, encryption, extended instruction sets, and memory bandwidth-sensitive tasks, the Intel Core Ultra 5 225H is superior. The data suggests that the Intel chip is a more balanced and broadly capable processor for mobile use, while the AMD Ryzen 7 6800HS retains a foothold in specialized integer and compression scenarios. The average benchmark scores place both parts within 2.7% of each other, but the distribution of wins heavily favors Intel.
