AMD Ryzen 7 5825C

The AMD Ryzen 7 5825C is a mobile processor from the 5000 series, built on the Zen 3 architecture (Cezanne-U) using a 7 nm process from TSMC. It packs 8 cores and 16 threads, with a base clock of 2.0 GHz and a boost clock of 4.5 GHz. The chip is designed for the FP6 socket and integrates a Radeon Vega 8 GPU. With a 15 W TDP, it targets thin-and-light laptops while still offering substantial multi-threaded performance.

Benchmark Performance

Benchmark results place the 5825C in the 58th percentile of all CPUs, with an average benchmark score of 3579. This puts it in the middle of the performance spectrum, not a flagship but far from a weakling. In Cinebench R23, the chip scores 12376 in multi-core and 1747 in single-core. The R20 scores are 5197 and 733, while R15 yields 1247 and 175 for multi and single, respectively. These numbers indicate a balanced processor that can handle both parallel and lightly-threaded workloads.

The average score of 3579 is nearly identical to that of the nearest rivals. The Ryzen 5 PRO 5650U scores 3587, giving the 5825C a 0.2% deficit. The Intel Core i7-5960X scores 3570, which is 0.2% lower than the 5825C, meaning the 5825C holds a 0.2% advantage. The Core i5-10600K leads the group with 3588, 0.3% ahead of the 5825C. The Xeon W-1290TE trails at 3566, leaving the 5825C 0.4% ahead. These sub-percent deltas show that the 5825C sits in a tightly contested performance tier, where differences are negligible in real-world use. The data suggests that the chip is effectively a peer to these established parts, with no single rival holding a meaningful edge.

Platform and Compatibility

The 5825C uses AMD Socket FP6, a mobile platform that dictates the physical and electrical design of the motherboard. It supports dual-channel DDR4 memory with a theoretical bandwidth of 51.2 GB/s. ECC memory is not supported, so error-correcting RAM is out of the question. The CPU provides 8 PCIe Gen 3 lanes (CPU only), which is typical for a mobile chip; this limits expansion options for high-bandwidth devices like discrete GPUs or NVMe drives, though the integrated Radeon Vega 8 GPU covers basic display needs. The cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a shared 16 MB L3 cache. The processor was released on May 4, 2022, and remains in active production. The multiplier is locked, so overclocking is not available. The part number is 100-000000xxx. For a mobile platform, the upgrade path is inherently limited—users typically cannot swap the CPU in a soldered laptop, and the FP6 socket is not a mainstream desktop interface.

Power and Thermals

With a TDP of just 15 W, the 5825C is designed for power-efficient mobile devices. This low thermal envelope allows for compact cooling solutions, often passive or low-profile fans in thin notebooks. The 7 nm process from TSMC, which integrates 10,700 million transistors on a 180 mm² die, contributes to the chip's efficiency. The boost clock of 4.5 GHz is notable given the 15 W limit, indicating that the Zen 3 cores can reach high frequencies under short bursts. Sustained multi-core workloads may be limited by the thermal budget, but the Cinebench R23 multi-core score of 12376 suggests the chip can sustain respectable performance. The 15 W TDP class places it in the same league as other ultra-low-power mobile processors, making it a candidate for fanless designs or devices that prioritize battery life over raw throughput.

How It Compares

AMD Ryzen 5 PRO 5650U: This rival averages 3587, a 0.2% advantage over the 5825C. The two chips are effectively indistinguishable in average performance, making the choice dependent on other factors like availability or platform features.

Intel Core i7-5960X: With an average score of 3570, the 5960X is 0.2% slower than the 5825C. The 5825C edges out this Intel part, showcasing the efficiency of the Zen 3 architecture despite the 5825C's lower TDP.

Intel Core i5-10600K: The 10600K leads this group with 3588, 0.3% ahead of the 5825C. This is a small margin, but it indicates that the 5825C can hold its own against a desktop mid-range CPU from Intel, albeit in a different power class.

Intel Xeon W-1290TE: This Xeon averages 3566, which is 0.4% behind the 5825C. The 5825C outperforms it, despite the Xeon's workstation branding, likely due to the higher boost clock and modern architecture.

Who Should Consider It

Given its 8-core/16-thread configuration and a Cinebench R23 multi-core score of 12376, the 5825C is well-suited for multitasking and productivity workloads such as office applications, web browsing, and light content creation. The single-core score of 1747 ensures responsive performance in everyday tasks. The integrated Radeon Vega 8 GPU eliminates the need for a discrete graphics card in basic use cases, making it a candidate for thin-and-light laptops aimed at students or business users. However, for tasks that require sustained high performance, the 15 W TDP may limit the chip's ability to maintain peak boost clocks. The 58th percentile ranking suggests it sits in the mid-range of all CPUs, so it is not a top-tier choice for heavy 3D rendering or high-refresh-rate gaming, but it offers a solid balance for general-purpose computing.

Single-Thread vs Multi-Thread Behavior

The 5825C's Cinebench R23 scores show a multi-core figure of 12376 against a single-core figure of 1747. The large gap reflects the scaling from 8 cores and 16 threads. Single-thread performance benefits from the 4.5 GHz boost clock, which is high for a 15 W part. This means applications that rely on one or two threads—such as spreadsheets, web browsers, and some legacy software—will see snappy performance. Multi-threaded workloads, including video encoding, 3D rendering, and compilation, will leverage the full core count, though the 15 W TDP defines a power envelope that may affect sustained multi-core performance. The 16 MB shared L3 cache helps reduce latency when multiple cores access common data, further aiding multi-threaded efficiency. The data implies that the 5825C is a versatile chip that can switch between bursty single-thread tasks and longer multi-threaded jobs, but with a ceiling imposed by its mobile power budget.
