AMD Ryzen Embedded 8640U

AMD’s Ryzen Embedded 8640U is a 6-core, 12-thread Zen 4 processor in the 8000 series, built under the Hawk Point codename on TSMC’s 4 nm process. It combines a 3.50 GHz base clock and a 4.90 GHz boost clock with a 28 W TDP, placing it in the low-power mobile and embedded segment. The chip includes a Radeon 760M integrated GPU, dual-channel DDR5 memory support with 89.6 GB/s of bandwidth, PCIe Gen 4 with 20 CPU lanes, and AMD Socket FP8 as its interface. The database entry lists no scored benchmarks, an empty nearestRivals field, an average benchmark score of 0, and a 50th percentile standing among all CPUs; those data caveats shape every comparison below.

How It Compares

The nearestRivals list is empty. There are no named rival processors, no rival scores, and no deltaPct values to quote. The 8640U cannot be positioned against a specific competitor in this database, and any exact percentage lead or deficit would be unsupported by the data.

The only relative signal is the percentileVsAllCpus field, which reports 50. In percentile terms, that would place the part in the middle of the CPU landscape. But because the benchmark array is empty and the average benchmark score is 0, that placement is not backed by measured results. It should be treated as an unverified ordinal position rather than a tested performance ranking.

What is known is where the part sits inside AMD’s own lineup. It belongs to the 8000 series, uses the Zen 4 architecture, and carries the Hawk Point codename. The generation is listed as Ryzen Embedded (Zen 4 (Hawk Point)). That places it in the same architectural generation as other Zen 4 embedded and mobile parts, but no direct database comparison is available.

Platform and Compatibility

The 8640U is built for AMD Socket FP8. The architecture is Zen 4, the codename is Hawk Point, and the generation is Ryzen Embedded (Zen 4 (Hawk Point)). The processor is manufactured by TSMC on a 4 nm process, with a die size of 178 mm² and a transistor count of 25,000 million. It is classified as a Mobile part, and production status is Active.

Memory support is DDR5 on a dual-channel bus, with 89.6 GB/s of bandwidth. ECC memory is supported, which is relevant for embedded reliability and data integrity. PCIe support is Gen 4 with 20 lanes available from the CPU only; no chipset lane allocation is provided in the data.

The upgrade path is defined by the socket and market segment. FP8 is an embedded and mobile interface, so this is not a general desktop upgrade part; it belongs in systems designed around that socket. The multiplier is not unlocked, so user-controlled frequency scaling is not part of the platform’s intended capability. The integrated graphics are provided by a Radeon 760M, so a discrete GPU is not strictly required for systems that can use the integrated GPU.

Benchmark Performance

There are no benchmark scores in the database for the Ryzen Embedded 8640U. The benchmarks array is empty, the average benchmark score is 0, and nearestRivals is empty. As a result, exact performance deltas, both absolute and relative, cannot be reported. This section can only describe the specification-level performance profile.

The core arrangement is 6 cores and 12 threads. The base clock is 3.50 GHz, and the boost clock is 4.90 GHz. That clock range indicates a processor that can raise frequency substantially when workload and thermal conditions allow. The cache hierarchy supplies 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The 16 MB L3 is the total shared pool across the 6 cores.

Memory bandwidth is 89.6 GB/s over dual-channel DDR5. This provides data throughput for both the CPU cores and the Radeon 760M integrated GPU. PCIe Gen 4 with 20 CPU lanes gives this embedded part a current I/O interface, though no lane allocation details are given. The Radeon 760M is present as integrated graphics, but no graphics benchmark data exists in the pack, so graphics performance cannot be quantified.

Without benchmark data, the 50th percentile field is the only score-adjacent metric. It is not corroborated by any average benchmark score, so the data does not support a claim that this part performs at the median of all CPUs; it simply lists that percentile value. No rival comparisons are present to anchor the number.

The locked multiplier is also relevant to performance expectations. Because the multiplier is not unlocked, overclocking is not part of the intended use case. Performance must come from the factory frequency range of 3.50 GHz to 4.90 GHz, the 6-core/12-thread Zen 4 layout, and the memory subsystem rather than from user tuning.

Who Should Consider It

Workload recommendations must be grounded in the absence of measured scores. With an empty benchmark array, there is no data showing how this part performs in specific games or applications. The specification profile, however, gives a clear shape.

For office and general productivity, the 6-core/12-thread Zen 4 design with 3.50 GHz base and 4.90 GHz boost clocks should handle typical multitasking and interactive work. The 28 W TDP also makes it suitable for compact embedded systems where space and cooling are limited. ECC memory support is a plus for data integrity in office and backend tasks, though it is not a performance guarantee.

For content creation, the configuration suits moderately threaded workloads. 6 cores and 12 threads are enough for many rendering and encoding tasks, but they are not a high-core-count processor. The 16 MB shared L3 and 89.6 GB/s memory bandwidth provide the memory subsystem for such work. Without benchmark scores, no exact ranking against other creation-class CPUs is possible.

For gaming, the Radeon 760M integrated GPU is the relevant hardware. It means the CPU has graphics capability on die. But because no graphics or gaming benchmark results are listed, the data cannot state expected frame rates or quality settings. This is an embedded and mobile part, so it is not positioned as a dedicated gaming processor; the integrated GPU is a general-purpose display and graphics output feature rather than a high-end gaming solution.

The likely audience is system integrators and embedded designs that need a 28 W, 6-core Zen 4 processor with DDR5, ECC, PCIe Gen 4, and integrated Radeon graphics, all on Socket FP8. It is not for users looking for a desktop overclocking part, since the multiplier is locked and the market segment is Mobile.

Power and Thermals

The 8640U is rated at a 28 W TDP. That is the thermal design power class, and it appears directly in the fact pack. The data does not specify a cooler model, required airflow, or chassis type.

A 28 W TDP implies a modest cooling tier. Low-profile coolers, thermal modules, or chassis-integrated thermal solutions typical of embedded and mobile systems should be sufficient to manage the heat output. There is no evidence in the data that high-end desktop cooling is required.

The 4 nm TSMC process and the Zen 4 architecture are consistent with the low power target. The die integrates 25,000 million transistors into 178 mm², and the 28 W envelope is the power constraint. Because the multiplier is locked, user-controlled voltage and frequency tuning is not an expected thermal variable. The production status is Active, meaning this is a current part in the 8000 series with a release date of 2024-04-01.
