AMD Ryzen 5 4680U

AMD Ryzen 5 4680U is a mobile processor from AMD’s 4000 series, built on the Zen 2 architecture under the Renoir codename. It integrates 6 cores and 12 threads, with a base clock of 2.20 GHz and a boost clock of 4.00 GHz, positioning it as a mid-tier option for thin-and-light laptops. The chip is manufactured on TSMC’s 7 nm process node, containing 9,800 million transistors on a 156 mm² die. With a production status of end-of-life and a release date of April 12, 2021, this part targets the mobile segment with integrated Radeon Graphics featuring 448 shader processors.

Platform and Compatibility

The AMD Ryzen 5 4680U uses the AMD Socket FP6, which is a BGA (ball-grid array) package designed for soldered installation in laptops, not for user upgrades in desktop systems. This socket is specific to the Renoir generation of mobile processors, meaning the upgrade path is limited to what the original laptop manufacturer provides—there is no socket-level interchangeability with other AMD platforms. The chip belongs to the 4000 series, which is part of the broader Zen 2 family, and its codename Renoir indicates a unified design for both CPU and integrated GPU on a single die.

Memory support is restricted to LPDDR4, operating in dual-channel mode. The system memory bandwidth is rated at 34.1 GB/s, which is typical for low-power mobile platforms of this era. ECC memory is not supported, so the processor cannot be used in error-correcting memory configurations. The memory controller is integrated into the chip, and the dual-channel bus is the primary data path for both CPU and GPU workloads. This LPDDR4 support means the platform is oriented toward power-efficient designs rather than maximum memory throughput.

For expansion, the Ryzen 5 4680U provides PCI-Express Gen 3 connectivity. This is the previous-generation interconnect standard, offering adequate bandwidth for NVMe storage and discrete GPUs in laptops, though not the newer Gen 4 or Gen 5 standards found in later platforms. The integrated Radeon Graphics 448SP handles display output, and the chip does not include a multiplier unlock, so overclocking is not possible. The part number is 100-000000356, and it is not listed with a launch MSRP, indicating it was likely sold in bulk to OEMs rather than as a retail product.

Power and Thermals

The Ryzen 5 4680U has a thermal design power (TDP) of 15 watts, placing it in the ultra-low-power class for mobile processors. This TDP is the configurable envelope that laptop designers use to balance performance against cooling capacity. A 15 W TDP implies the chip is suitable for passive or low-noise cooling solutions in thin notebooks, or for active cooling with a single heat pipe and a small fan in more performance-oriented ultrabooks. The low power budget means sustained multi-core workloads will be constrained by thermal limits, but bursty single-thread tasks can reach the 4.00 GHz boost clock without excessive heat.

Cooling tier implications are straightforward: the 15 W envelope allows for a compact cooler, typically a low-profile heatsink with a small blower fan, which is common in 13- to 14-inch laptops. The 7 nm process node from TSMC helps reduce power density, but the 9,800 million transistors on a 156 mm² die still require adequate heat dissipation for sustained boosts. Benchmark results indicate a 50th percentile ranking among all CPUs, meaning the chip is about average in overall performance, which aligns with its modest power budget. The absence of a multiplier unlock confirms that thermal and power behavior is fixed by the OEM’s firmware, not user-adjustable.

How It Compares

The Ryzen 5 4680U does not have nearest rival data in the provided fact pack, so direct comparisons to specific competing processors are not available from this dataset. The percentileVsAllCpus field shows a value of 50, which means the chip sits at the median performance level across all CPUs in the benchmark database. This is a neutral position—neither a standout performer nor a laggard—indicating that it delivers typical performance for its class. Without nearestRivals entries, the analysis must rely on the percentile and the architectural characteristics to infer its standing.

Given the Zen 2 architecture and 6-core/12-thread configuration, the Ryzen 5 4680U would logically compete with other 15 W mobile processors from the same era, such as Intel’s low-power quad-core parts, but the fact pack does not list those rivals. The integrated Radeon Graphics 448SP adds value for light gaming and media tasks, but the lack of rival specs means no quantitative comparison can be made. The 34.1 GB/s memory bandwidth is a key constraint for graphics performance, yet without rival numbers, it is not possible to say if this is ahead or behind. Benchmark scores are listed as zero in the benchmarks array, and the avgBenchmarkScore is also zero, so no direct score-based comparison is possible.

Benchmark Performance

The benchmark data for the Ryzen 5 4680U is sparse: the benchmarks array is empty, and the avgBenchmarkScore is zero. The only meaningful metric is percentileVsAllCpus, which is 50. This percentile indicates that the processor performs better than 50% of all CPUs tracked in the database, placing it exactly at the median. This is a significant finding because it shows the chip is not a high-end part, nor is it a low-end one—it sits in the middle of the performance distribution.

Without nearestRivals data, it is impossible to calculate exact percentage deltas against competitors. However, the percentile can be interpreted in context: a 50th percentile ranking suggests that the Ryzen 5 4680U delivers balanced performance for everyday tasks, such as web browsing, office productivity, and light content creation. The 6-core/12-thread configuration provides decent multi-threaded throughput, but the 15 W TDP limits sustained performance compared to higher-power parts. The boost clock of 4.00 GHz helps single-thread responsiveness, while the base clock of 2.20 GHz indicates the chip will downclock under heavy multi-core loads to stay within thermal limits.

The integrated Radeon Graphics 448SP is a notable feature, as it allows the chip to handle basic graphics workloads without a discrete GPU. However, the 34.1 GB/s memory bandwidth shared between CPU and GPU can become a bottleneck in graphics-intensive scenarios. The 8 MB of shared L3 cache and per-core L1 (64 KB) and L2 (512 KB) caches are moderate by modern standards, but they are sufficient for the intended mobile usage. The 7 nm process node and 15 W TDP mean the chip is efficient, which is a common trade-off in this market segment: performance is sacrificed for battery life and thermal comfort.

In the absence of rival benchmarks, the percentile is the only comparative tool. A 50th percentile ranking is neither impressive nor disappointing—it is simply average. For a laptop buyer, this means the Ryzen 5 4680U will handle typical workloads without issues, but it will not excel in demanding applications like video editing or 3D rendering. The end-of-life production status also suggests that this chip is a mature product, and newer processors in the 5000 or 7000 series would likely offer better performance per watt, but those are not in the fact pack for comparison. Overall, the data shows a competent mid-range mobile processor whose performance is exactly at the midpoint of all CPUs in the database.
