AMD Ryzen 3 7330U

The AMD Ryzen 3 7330U is a mobile processor from the 7000 series, built on the Zen 3 architecture and codenamed Barcelo-R. It features 4 cores and 8 threads, with a base clock of 2.30 GHz and a boost clock of 4.30 GHz. This chip is manufactured on a 7 nm process at TSMC, occupying a die size of 180 mm² with 10,700 million transistors, and it sits in the 52nd percentile of all CPUs tested in the database.

Benchmark Performance

The Ryzen 3 7330U delivers a balanced performance profile across synthetic workloads. In Cinebench R23, the processor scores 9,128 points in multi-core and 1,288 points in single-core tests. These results indicate a strong showing for a 15-watt mobile part, with the multi-core score reflecting the efficiency of the 4-core/8-thread configuration under sustained load. The single-core score of 1,288 demonstrates that the Zen 3 architecture provides competitive per-thread performance, which is crucial for everyday responsiveness.

Looking at other benchmarks, the chip achieves 3,833 points in Cinebench R20 multi-core and 540 points in single-core, while in Cinebench R15, it scores 919 multi-core and 129 single-core. Geekbench results show 4,131 multi-core and 1,514 single-core. The average benchmark score across all tests is 2,685, placing this processor in a tight cluster with its nearest rivals. The deltaPct values versus these competitors are extremely narrow: the Ryzen 3 7330U is statistically tied with the Intel Core 3 N355 (0% delta), just 0.4% ahead of the Intel Core i5-9500F, 0.6% ahead of the Intel Core i5-1335UE, and 0.8% ahead of the Intel Xeon E5-4650 v3. These margins are within run-to-run variance for most benchmarking suites, meaning the 7330U offers essentially equivalent aggregate performance to these alternatives.

The percentile ranking of 52 indicates that this processor outperforms slightly more than half of all CPUs in the database, which is a respectable position for a low-power mobile chip. The consistent scores across Cinebench and Geekbench suggest that the 7330U maintains its performance across different workload types, from ray tracing to general-purpose compute. The data shows no significant anomaly in any single test, pointing to a well-balanced design rather than a part optimized for one specific scenario.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance reveals a processor that excels in burst workloads. In Cinebench R23, the single-core score of 1,288 represents about 14.1% of the multi-core score, which is typical for a 4-core part — the ratio indicates that scaling from one core to all cores is nearly linear, with minimal overhead from thread synchronization. This suggests that the 8 threads are effectively utilized across the four physical cores.

For real-world workloads, the single-thread performance is what users will notice first. The Geekbench single-core score of 1,514 and Cinebench R20 single-core score of 540 indicate that the 7330U handles web browsing, office applications, and other lightly-threaded tasks with ease. The boost clock of 4.30 GHz is key here, as it allows the processor to quickly ramp up for short bursts of activity. In contrast, the multi-thread scores of 9,128 in Cinebench R23 and 4,131 in Geekbench show that the chip can sustain productivity loads like video transcoding or software compilation, though the 15-watt TDP limits how long it can maintain peak multi-core performance.

The behavior across benchmarks is consistent: single-thread scores are proportionally strong relative to multi-thread scores. This indicates that the Zen 3 cores are efficient at both low and high occupancy, with the shared 8 MB L3 cache helping to reduce latency when all cores are active. For users who predominantly run single-threaded applications, the 7330U punches above its class; for those running heavily threaded workloads, it performs as expected for a quad-core mobile chip. The 2.30 GHz base clock ensures that even under sustained all-core loads, the processor does not throttle below a usable frequency, though the boost to 4.30 GHz is reserved for lighter, shorter tasks.

How It Compares

vs. Intel Core 3 N355: The Ryzen 3 7330U and the Intel Core 3 N355 are effectively tied, with a deltaPct of 0% and nearly identical average scores (2,685 vs. 2,684). This means that in aggregate benchmarks, there is no measurable performance difference between them. The 7330U offers a newer architecture and a higher boost clock, but the N355 matches it in overall throughput, making this a head-to-head competition decided by other factors like platform features.

vs. Intel Core i5-9500F: The 7330U edges out the Intel Core i5-9500F by 0.4%, with average scores of 2,685 versus 2,674. The i5-9500F is a desktop part with a higher TDP, yet the mobile 7330U manages to slightly outperform it in these composite benchmarks. This is a notable result, as it shows the efficiency of the Zen 3 architecture — a 15-watt mobile chip can keep pace with a desktop mainstream processor from the same era.

vs. Intel Core i5-1335UE: The Ryzen 3 7330U leads the Intel Core i5-1335UE by 0.6%, with average scores of 2,685 versus 2,670. The i5-1335UE is also a low-power mobile chip, but the 7330U's higher boost clock and efficient cores give it a slight edge in these tests. The margin is small, but it demonstrates that AMD's 4-core design competes well against Intel's hybrid architecture in this power class.

vs. Intel Xeon E5-4650 v3: The 7330U outperforms the Intel Xeon E5-4650 v3 by 0.8%, with average scores of 2,685 versus 2,664. The Xeon is a server-class processor with many more cores, yet its lower per-core performance drags its aggregate score down. This comparison highlights how the 7330U's strong single-thread capabilities can overcome a core-count disadvantage, at least in the synthetic workloads captured by these benchmarks.

Power and Thermals

The AMD Ryzen 3 7330U is rated at a TDP of 15 watts, which classifies it as a low-power mobile processor designed for thin-and-light laptops. This TDP class implies that a capable air cooler, such as a slim heat pipe assembly or a small vapor chamber, is sufficient to manage thermals. The 7 nm process node helps keep power density low, allowing the chip to maintain its 4.30 GHz boost clock without requiring aggressive cooling solutions.

Given the 15-watt TDP, the 7330U is suitable for passively cooled designs in some cases, though most laptops will pair it with a low-profile fan for sustained workloads. The base clock of 2.30 GHz ensures that the processor can run at its full multi-threaded capability without exceeding the thermal envelope, while the boost clock provides headroom for single-threaded tasks. Benchmark results show that the chip delivers competitive performance within this power class, matching or slightly exceeding rivals that may have higher TDPs. The lack of an unlocked multiplier means overclocking is not possible, but this is typical for mobile processors where power efficiency is prioritized over raw speed. Overall, the 7330U offers a well-balanced combination of performance and efficiency, making it a solid choice for mainstream laptops that need dependable multi-core capability without excessive heat generation.
