AMD Ryzen 5 40

The AMD Ryzen 5 40 is a 4-core, 8-thread mobile processor built on the Zen 2 architecture with the Mendocino codename, manufactured by TSMC on a 6 nm process. The database record lists a 50th percentile standing among all CPUs, but it also contains an empty benchmark array and an empty nearestRivals list, so measured score deltas cannot be derived from this fact pack.

Benchmark Performance

The facts available for the Ryzen 5 40 include no executed benchmark results. The benchmarks field is empty, and the listed average benchmark score is 0. Because the nearestRivals array is empty, there are no rival names, no rival scores, and no deltaPct values to report. This means the current record cannot be used to quantify how far the processor is ahead or behind another product in any workload.

The only comparative field present is percentileVsAllCpus, which is 50. That places the part at the midpoint of the distribution sampled by the database. Taken literally, the 50th percentile places this part centrally within the database's CPU population. But with no benchmark scores underneath the percentile, the practical meaning is limited. The record does not provide a score for a single-thread test, a multi-core test, a graphics test, or a power-normalized test. Therefore, any interpretation of benchmark performance must rely on the specification list rather than measured results.

The specification list provides the CPU's operating envelope: 4 cores, 8 threads, a base clock of 2.80 GHz, and a boost clock of 4.30 GHz. Those values are input conditions for potential performance, not outputs of a benchmark. Without score data, the 50th percentile remains a database-level categorization, not a performance proof.

Power and Thermals

The Ryzen 5 40 carries a TDP of 15 W. That is the defining thermal constraint in the fact pack. The processor is assigned to the Mobile market segment, uses AMD Socket FT6, and is built by TSMC on a 6 nm process with a die size of 100 mm². A 15 W TDP, a mobile socket, and a 6 nm process all point to a low-power cooling tier. The cooling solution for a system built around this chip would need to handle a modest thermal load rather than a desktop-class one, though the exact cooler type is not specified in the data.

The memory subsystem is also part of the platform picture. The processor supports LPDDR5 memory on a dual-channel bus, with 88.0 GB/s of memory bandwidth. The dual-channel interface supplies memory bandwidth while keeping the overall platform in the mobile segment. The fact pack lists the production status as Active, meaning the part is currently in production rather than discontinued.

The process details are relevant to thermals as well. The CPU is fabricated on a 6 nm node at TSMC and has a 100 mm² die size. No power draw figures are included beyond the 15 W TDP. A 15 W mobile processor with a 6 nm process and an Active production status is fundamentally a low-heat part. The platform also has PCIe Gen 3 with 4 lanes allocated to the CPU, which is consistent with a compact mobile system rather than a high-power expansion environment. The exact cooling tier is not named, but the 15 W TDP sets a clear expectation for a lightweight thermal solution.

Single-Thread vs Multi-Thread Behavior

The Ryzen 5 40 has 4 physical cores and 8 threads. This means it can handle 8 logical threads simultaneously. The base clock is 2.80 GHz and the boost clock is 4.30 GHz. The gap between the base and boost clocks indicates that the CPU is capable of raising frequency on lightly loaded threads, but the fact pack does not specify the conditions under which the boost clock applies, so no direct single-thread versus multi-thread frequency claim can be made.

The cache hierarchy is fully listed. Each core has 64 KB of L1 cache and 512 KB of L2 cache. The processor shares a 4 MB L3 cache across all cores. The L3 capacity is a fixed fact, but the fact pack does not provide measurements of cache latency or hit rates. In multi-threaded work, the 8 threads give the part more compute contexts than its 4 physical cores. In single-threaded work, the 4.30 GHz boost clock is the highest frequency listed, which could offer quick response in lightly threaded applications, although no benchmark confirms this.

The memory interface for the Ryzen 5 40 is dual-channel LPDDR5 with 88.0 GB/s of bandwidth. This supports both single- and multi-threaded workloads by moving data into and out of the 4 MB shared L3 cache. The CPU also supports PCIe Gen 3 with 4 lanes, which is the CPU-side expansion interface. The fact pack contains no benchmark results for single-thread or multi-thread tests, so the actual ratio between single-thread and multi-thread behavior cannot be expressed as a number. What can be expressed is the specification pattern: an 8-thread Zen 2 mobile processor with a 4.30 GHz boost clock and a 4 MB shared L3 cache.

Who Should Consider It

The Ryzen 5 40 is a mobile processor with a 15 W TDP, so the data suggests systems designed around portability rather than sustained maximum compute. Office workloads are a reasonable fit from the specification list: 4 cores and 8 threads allow document, spreadsheet, or web applications to run concurrently, and the 4.30 GHz boost clock gives headroom for short bursts of activity. The processor includes the Radeon 610M integrated graphics, so a dedicated GPU is not required for basic display output.

For gaming, the situation is constrained. The fact pack lists Radeon 610M as the integrated graphics solution, but it contains no gaming benchmark scores for the Ryzen 5 40. It is therefore not possible to state which games or resolution settings the iGPU can handle. The PCIe Gen 3 with 4 lanes is the only CPU-side PCIe resource, so any discrete graphics option would be limited by the platform's lane assignment. The data does not show whether a separate GPU can be attached at all.

For creation work, the core and cache profile matters. 4 cores, 8 threads, and 4 MB of shared L3 is not a high-core-count configuration. Rendering, video encoding, and other heavily parallel creation tasks would likely rely on the 8 threads, but the record contains no rendering or encoding scores. The 88.0 GB/s dual-channel LPDDR5 bandwidth is present, which benefits memory-sensitive tasks, but the absence of benchmark data prevents a specific recommendation for creation workloads.

The release date in the fact pack is 2025-09-30, and the production status is Active. This makes the Ryzen 5 40 a current mobile option, not a legacy part. The multiplier is not unlocked, meaning the fact pack does not support overclocking as a feature. Users who need a low-power, currently produced mobile processor with 8 threads, integrated Radeon 610M graphics, and LPDDR5 memory support are the clear audience. Users who need quantified performance leadership in gaming or multi-core creation should note that no comparative score data exists in the fact pack.
