AMD Ryzen 9 PRO 6950HS vs Intel Core Ultra 5 225H Comparison

The AMD Ryzen 9 PRO 6950HS and Intel Core Ultra 5 225H are both mobile processors aimed at high-performance laptops, but the benchmark data presents a stark contrast in their capabilities. The Intel part wins 16 of the 17 head-to-head comparisons, often by substantial margins, while the AMD chip secures a single, albeit significant, victory in integer math. This analysis breaks down the specific benchmark results, architectural underpinnings, and the practical implications of these scores for different user workloads.

Head-to-Head Benchmarks

The most decisive wins for the Intel Core Ultra 5 225H come in compute-heavy workloads. In Cinebench R23, the Intel chip scores 14629.5 points in the multi-core test, which is 21.3% higher than the AMD Ryzen 9 PRO 6950HS’s score of 11515. The single-core advantage is even more pronounced, with the Ultra 5 achieving a 23.1% lead (1969 vs. 1514). This pattern is consistent across other CPU-centric benchmarks. In Geekbench, the Intel part leads by 24% in multi-core (11526 vs. 8756) and by 11.5% in single-core (2151 vs. 1903). The data indicates that the Intel processor provides a generational leap in both lightly-threaded and fully-threaded performance.

The largest deltas appear in specialized Passmark tests. The most extreme example is the `passmark_find_prime_numbers` test, where the Intel Core Ultra 5 225H scores 220, a massive 74.5% improvement over the AMD’s score of 56. This test is highly sensitive to architectural efficiency and clock speed, and the Intel chip's performance here is exceptional. Similarly, in `passmark_floating_point_math`, the Intel CPU’s score of 86540 is 44.4% higher than the AMD’s 48096. The same 44.4% delta is seen in `passmark_physics` (1877 vs. 1043), showing a clear advantage in simulations and physics calculations that rely heavily on floating-point throughput.

While the Intel chip dominates the overall scoreboard, the AMD Ryzen 9 PRO 6950HS has one clear counterpunch. In `passmark_integer_math`, the AMD processor scores 88124, which is a 28.6% lead over the Intel's 68520. This is a substantial win and indicates that for certain integer-heavy tasks, the AMD architecture is significantly more efficient. Other wins for Intel are more modest, such as the 0.3% lead in `passmark_data_compression` (283451 vs. 282624) and a 12.8% lead in `passmark_random_string_sorting` (33654 vs. 29350). The Intel chip also shows a 16.8% lead in `passmark_data_encryption` (21428 vs. 17837) and a 13.8% lead in `passmark_extended_instructions` (21915 vs. 18897).

Where Each One Wins

Based on the benchmark results, the Intel Core Ultra 5 225H is the clear winner for almost all demanding applications. Its 21.3% lead in Cinebench R23 multi-core and 19% lead in Passmark multithread (28119 vs. 22775) make it the superior choice for content creation, video editing, 3D rendering, and software compilation. These tasks utilize all available cores and threads, and the Intel chip's higher core count and per-core performance translate directly into faster completion times. The massive 44.4% advantage in floating-point math and physics also makes it the better option for scientific computing, engineering simulations, and any workload that uses complex mathematical models.

The Intel chip's single-core dominance, shown by a 23.1% lead in Cinebench R23 single-core and a 20.2% lead in Passmark single-thread (4258 vs. 3400), means it also excels in everyday responsiveness and lightly-threaded applications like web browsing, office productivity, and legacy software. The 11.5% lead in Geekbench single-core reinforces this, suggesting a snappier overall system feel.

The AMD Ryzen 9 PRO 6950HS, despite its overall performance deficit, has a specific niche. Its 28.6% lead in integer math is its only win. This suggests that for certain specific workloads, such as database operations, cryptography, or compression algorithms that are integer-based, the AMD chip may hold an advantage. However, this is a narrow use case. While the AMD chip is not the top performer in most areas, its single win is notable because it demonstrates that architectural design can lead to significant differences in specific, narrow test scenarios.

Architecture Differences

The performance gap can be largely attributed to the fundamental architectural differences between the two processors. The AMD Ryzen 9 PRO 6950HS is built on the Zen 3+ architecture, codenamed Rembrandt, using a 6 nm process node from TSMC. It has 8 cores and 16 threads. In contrast, the Intel Core Ultra 5 225H is based on the newer Arrow Lake architecture, codenamed Arrow Lake-H, and is manufactured on a more advanced 3 nm TSMC process node. The Intel chip has 14 cores and 14 threads.

The core count difference explains part of the multi-core performance gap, but the process node advantage also contributes to the Intel chip's efficiency and higher performance. The Intel chip has a larger L3 cache at 18 MB, compared to the AMD's 16 MB. The L1 and L2 cache configurations also differ significantly, with the Intel part featuring 192 KB of L1 and 3 MB of L2 per core, while the AMD part has 64 KB of L1 and 512 KB of L2 per core. This larger per-core cache on the Intel chip likely helps with its single-core and integer performance advantages.

Both processors support DDR5 memory, but the Intel chip also supports LPDDR5X and has a higher maximum memory bandwidth of 102.4 GB/s, compared to the AMD's 76.8 GB/s. This increased bandwidth can be beneficial for integrated graphics performance and memory-intensive tasks. The integrated GPUs also differ: the AMD has a Radeon 680M, while the Intel features Arc Graphics 130T. The Intel chip supports PCIe Gen 5 with 8 lanes, while the AMD chip uses the older PCIe Gen 4 with 20 lanes. The Intel chip also has a lower TDP of 28 watts compared to the AMD's 35 watts, which is notable given its higher performance.

The Verdict

The benchmark data is unambiguous: the Intel Core Ultra 5 225H is the significantly more powerful processor. It wins 16 out of 17 head-to-head benchmarks and leads by substantial margins in nearly every category that matters for general high-performance computing. Its 21.3% lead in Cinebench R23 multi-core and 23.1% lead in single-core are definitive. The data shows that for users who need maximum performance in multi-threaded applications like video editing, 3D rendering, or software development, the Intel Core Ultra 5 225H is the clear choice. Its 44.4% lead in floating-point math also makes it superior for scientific and engineering workloads.

The AMD Ryzen 9 PRO 6950HS, while the older and slower part, is not without its strengths. Its 28.6% lead in integer math is a notable exception and could be relevant for specific niche workloads. However, it cannot compete with the Intel chip on a general level. The data suggests that the Intel Core Ultra 5 225H should be selected for almost any new system build where performance is the primary concern. The AMD chip would only be a rational choice if a specific, known workload relies heavily on integer operations and the user is willing to sacrifice performance in all other areas.
