A: The Ryzen 5 150 has an average benchmark score of 34881, placing it in the 84th percentile of all CPUs. The Ryzen AI 7 445 has an average score of 26936, placing it in the 79th percentile. This discrepancy reflects differences in the benchmark suites recorded for each processor.

Architecture Differences

The Ryzen 5 150 uses the Zen 3+ architecture, codenamed Rembrandt-R, fabricated on a 6 nm process by TSMC. The Ryzen AI 7 445 uses the Zen 5 architecture, codenamed Gorgon Point, built on a 4 nm process, also by TSMC. This process shrink is significant, as it allows the Ryzen AI 7 445 to achieve higher clock speeds and better efficiency despite a lower TDP.

The Ryzen 5 150 has a base clock of 3.30 GHz and a boost clock of 4.55 GHz. The Ryzen AI 7 445 has a base clock of 2.00 GHz and a boost clock of 4.60 GHz. The lower base clock on the newer chip suggests a more aggressive power management strategy, while the slightly higher boost clock indicates headroom for short bursts of performance.

Cache organization differs substantially. The Ryzen 5 150 has 64 KB of L1 cache and 512 KB of L2 cache per core, with 16 MB of shared L3 cache. The Ryzen AI 7 445 has 80 KB of L1 cache and 1 MB of L2 cache per core, but only 4 MB of L3 cache. The larger per-core L1 and L2 caches on the Zen 5 part compensate for the smaller L3 pool, which may reduce latency for frequently accessed data.

The Ryzen 5 150 uses AMD Socket FP7, while the Ryzen AI 7 445 uses AMD Socket FP8. The integrated graphics differ as well: the Ryzen 5 150 features Radeon 660M graphics, while the Ryzen AI 7 445 features Radeon 840M. The newer Radeon 840M likely benefits from architecture improvements, though raw graphics benchmark data is not in the recorded set.

PCIe lane counts also separate the two. The Ryzen 5 150 offers Gen 4 with 20 lanes (CPU only), while the Ryzen AI 7 445 offers Gen 4 with 14 lanes (CPU only). This gives the Ryzen 5 150 more connectivity headroom for expansion devices.

Head-to-Head Benchmarks

The Ryzen AI 7 445 dominates the direct comparison in nine of eleven tests. The largest margin comes in the PassMark physics test, where the Ryzen AI 7 445 scores 976 versus 806 for the Ryzen 5 150, a 17.4% advantage. This suggests better handling of physics simulation workloads, likely due to the newer architecture's improved branch prediction and execution resources.

Single-thread performance shows a 12.1% gap, with the Ryzen AI 7 445 scoring 3591 against 3155 for the Ryzen 5 150 in both passmark_single_thread and passmark_singlethread tests. Floating-point math also favors the newer chip by 10.8%, with scores of 39362 and 35118 respectively. Extended instructions show a 7.3% lead for the Ryzen AI 7 445, at 15826 versus 14675.

Prime number finding, a test that stresses integer throughput and loop efficiency, sees the Ryzen AI 7 445 score 56 against 47 for the Ryzen 5 150, a 16.1% delta. Random string sorting shows a 4.7% lead for the Ryzen AI 7 445, and data compression shows a 2.1% lead, with scores of 215812 and 211289 respectively. Multithread performance favors the Ryzen AI 7 445 by 3.4%, scoring 18115 versus 17492.

The Ryzen 5 150 wins two tests. Data encryption shows a 27.6% advantage, with the Ryzen 5 150 scoring 13425 versus 10519 for the Ryzen AI 7 445. This is the largest single delta in either direction and indicates that the older chip's encryption execution path is more efficient, possibly due to dedicated instruction handling. Integer math also favors the Ryzen 5 150, scoring 62151 against 58332, a 6.5% advantage. This is curious given the Ryzen AI 7 445's lead in prime number finding, but it suggests the Zen 3+ core retains strength in certain scalar integer operations.

Where Each One Wins

The Ryzen AI 7 445 wins in scenarios that benefit from higher single-thread throughput, floating-point math, physics simulation, and general multi-threaded workloads. Its 12.1% single-thread lead makes it the better choice for lightly threaded applications such as web browsing, office productivity, and many legacy games that rely on one or two cores. The 10.8% floating-point advantage helps with scientific computing, 3D rendering, and audio processing. The 17.4% physics delta suggests stronger performance in game engines that offload physics to the CPU.

The Ryzen AI 7 445 also wins in data compression, extended instructions, prime number finding, and random string sorting. These tests imply better compiler-optimized code execution and more efficient handling of modern instruction sets. Its multithread lead of 3.4%, combined with a lower TDP of 28 watts versus 35 watts, makes it attractive for sustained workloads in thermally constrained chassis.

The Ryzen 5 150 wins in data encryption by a wide 27.6% margin and in integer math by 6.5%. These wins indicate that the Zen 3+ architecture retains an edge in certain cryptographic workloads, possibly due to more efficient AES or other cipher instruction timing. For integer-heavy tasks like database operations, compression algorithms that rely on integer arithmetic, or financial calculations, the Ryzen 5 150 offers a measurable advantage.

The Ryzen 5 150 also has more PCIe lanes (20 versus 14), which could matter for users who need to connect multiple NVMe drives, capture cards, or external GPU enclosures. Its larger 16 MB L3 cache versus 4 MB may benefit workloads with large working sets that fit within that pool.

The Verdict

The benchmark data points to the Ryzen AI 7 445 as the overall stronger processor for most tasks. It wins nine of eleven direct comparisons, including the single-thread, multithread, and floating-point tests that dominate typical usage patterns. Its higher boost clock of 4.60 GHz, newer Zen 5 architecture, and lower TDP of 28 watts make it a more efficient choice for modern ultraportable laptops. The support for LPDDR5X memory and ECC further broadens its appeal for both consumer and professional mobile systems.

However, the Ryzen 5 150 is not without merit. Its 27.6% lead in data encryption and 6.5% lead in integer math suggest that specific workloads, particularly those involving cryptography or integer-bound processing, would perform better on the older chip. The larger L3 cache and higher PCIe lane count provide additional flexibility for users who prioritize storage expansion or specialized peripherals. The Ryzen 5 150 also has a higher average benchmark score of 34881 compared to 26936, though this metric may reflect different test suites in the database.

For a typical mobile user running a mix of productivity, content creation, and everyday applications, the Ryzen AI 7 445 delivers more consistent wins across the recorded benchmarks. For a niche user whose primary workload involves encryption, integer-heavy algorithms, or requires extensive PCIe connectivity, the Ryzen 5 150 presents a compelling alternative. The data does not support a universal winner; it supports a split depending on the workload profile. The Ryzen AI 7 445 is the better general-purpose processor, while the Ryzen 5 150 excels in specific, narrowly defined areas.
