AMD Ryzen 5 4600U

The AMD Ryzen 5 4600U is a 6-core, 12-thread mobile processor from the 4000 series, built on TSMC's 7 nm process with the Zen 2 (Renoir) architecture. It operates at a base clock of 2.10 GHz and a boost clock of 4.00 GHz, with a 15 W TDP, making it a low-power part aimed at thin-and-light laptops. Its benchmark results place it at the 55th percentile of all CPUs, with an average benchmark score of 3200, positioning it as a solid mid-range mobile chip. This analysis examines how it stacks up against its nearest rivals, its single- and multi-thread behavior, its power and thermal profile, and its detailed benchmark performance.

How It Compares

The Ryzen 5 4600U's closest rival is the AMD Ryzen 7 4700U, which has an average benchmark score of 3215. The 4600U trails by 0.5%, a margin so small it falls within run-to-run variance. Both are Renoir parts, but the 4700U typically offers two extra cores; despite that, the 4600U's lower core count is nearly compensated by its higher boost clock in many workloads, keeping the average score almost identical.

Against the Intel Core i3-13100T, the 4600U also sits 0.5% behind (average score 3215). The i3-13100T is a desktop-class chip with a higher TDP, yet the 4600U's efficient Zen 2 architecture and 12 threads allow it to compete closely in average performance. The delta is negligible, meaning the 4600U holds its own against a modern desktop i3 in mixed workloads.

The AMD Ryzen 3 PRO 5350GE, a desktop APU, has an average score of 3218, putting the 4600U 0.6% behind. The 5350GE runs at a higher TDP and likely sustains higher clocks, but the 4600U's additional cores (6 vs 4) and threads help close the gap. Again, the difference is sub-percentage, indicating that the mobile 4600U is remarkably competitive with a desktop part in this metric.

The Intel Core i7-9700E, a low-power desktop processor, scores 3228 on average, leaving the 4600U 0.9% behind. The i7-9700E has 8 cores but no hyperthreading, while the 4600U has 6 cores with 12 threads. The 4600U's simultaneous multithreading and higher boost clock (4.00 GHz vs presumably lower) compensate for the core deficit, resulting in only a 0.9% gap. This positions the 4600U as a strong performer in its power class.

Single-Thread vs Multi-Thread Behavior

The 4600U's single-thread scores are modest: 160 in Cinebench R15, 667 in R20, 1589 in R23, and 1347 in Geekbench. These numbers are typical for a 15 W mobile chip with a 4.00 GHz boost. The single-thread performance is adequate for everyday tasks, but it is not class-leading; the Zen 2 architecture, while efficient, does not match the per-core performance of newer desktop designs.

Multi-thread performance is where the 4600U shines. With 6 cores and 12 threads, it achieves 1134 in Cinebench R15, 4728 in R20, and 11259 in R23. The ratio of multi-thread to single-thread scores is approximately 7.1x in Cinebench R20 and R23, which is close to the theoretical 6x scaling from cores plus hyperthreading overhead. This indicates excellent thread utilization, making the chip well-suited for video rendering, code compilation, and other parallel workloads.

The Geekbench multi-thread score of 4715 versus a single-thread score of 1347 yields a 3.5x scaling, which is lower than Cinebench because Geekbench's workload mix is less parallel. This suggests that the 4600U's advantage is most pronounced in heavily threaded, compute-intensive tasks, while it remains competent but not exceptional in lightly threaded applications.

Power and Thermals

The 4600U is rated at a 15 W TDP, classifying it as a low-power mobile processor. This design point prioritizes energy efficiency over raw performance, making it suitable for ultrabooks and thin laptops where cooling is limited. The 7 nm process from TSMC contributes to its efficiency, allowing the 6-core design to fit within a 15 W envelope without excessive heat generation.

The chip uses AMD Socket FP6, a BGA package, meaning it is soldered to the motherboard and not upgradeable. The integrated Radeon RX Vega 6 GPU shares the thermal budget with the CPU cores, but the 15 W TDP implies that a modest cooling solution—such as a thin heat pipe and small fan—is sufficient to sustain boost clocks under load. The low power draw also enables fanless designs in some chassis, though the Vega 6 iGPU may produce additional heat during graphics-intensive tasks.

Given the 15 W TDP and 7 nm node, the 4600U sits in the same efficiency class as other Renoir parts. Its base clock of 2.10 GHz and boost of 4.00 GHz are achievable within this power envelope, but sustained all-core workloads may cause the boost clock to drop if the cooling solution is inadequate. Benchmark results indicate that the chip can deliver strong multi-thread performance without exceeding its thermal design point.

Benchmark Performance

The Ryzen 5 4600U's average benchmark score is 3200, placing it at the 55th percentile of all CPUs. This means it outperforms more than half of the processors in the database, a respectable showing for a 15 W mobile chip. Its nearest rivals all have average scores within a fraction of a percent: the Ryzen 7 4700U and Core i3-13100T at 3215 (0.5% higher), the Ryzen 3 PRO 5350GE at 3218 (0.6% higher), and the Core i7-9700E at 3228 (0.9% higher). These deltas are negligible, indicating that the 4600U delivers performance essentially on par with these competing parts.

In Cinebench R15, the 4600U scores 1134 multi-core and 160 single-core. The multi-core score reflects strong scaling from its 12 threads, while the single-core score is typical for a 4.00 GHz Zen 2 core. The R20 results are 4728 multi-core and 667 single-core, showing a similar pattern. The R23 multi-core score of 11259 is particularly notable, as it exceeds the 10,000-point threshold that many desktop processors achieve, yet the 4600U does so within a 15 W power envelope. Its R23 single-core score of 1589 is modest but sufficient for responsive everyday use.

Geekbench results are 4715 multi-core and 1347 single-core. The multi-core score is consistent with other 6-core/12-thread parts, while the single-core score is slightly lower than some desktop counterparts due to power limits. The overall benchmark profile suggests that the 4600U is best suited for workloads that leverage multiple threads, such as video encoding, 3D rendering, and scientific simulations. For single-threaded tasks like web browsing or office applications, it performs adequately but does not stand out.

When compared to its rivals, the 4600U's performance is tightly clustered. The 0.5-0.9% differences are within measurement error and unlikely to be perceptible in real-world use. This means that the 4600U can be considered a peer of the Ryzen 7 4700U, Core i3-13100T, Ryzen 3 PRO 5350GE, and Core i7-9700E in overall performance, despite differences in core counts, TDP, and market segment. The data shows that the 4600U achieves this parity through a combination of efficient Zen 2 cores, a high boost clock, and simultaneous multithreading, making it a compelling choice for ultraportable laptops that need solid multi-core performance without sacrificing battery life.
