AMD Ryzen 5 PRO 5655G

AMD Ryzen 5 PRO 5655G is a 6-core, 12-thread desktop processor built on the Zen 3 architecture and Cezanne codename, using the AMD Socket AM4 platform. It operates with a base clock of 3.90 GHz and a boost clock of 4.40 GHz, with a 65W TDP. The chip is manufactured on a 7nm TSMC process, containing 10,700 million transistors on a 180 mm² die. It sits at the 85th percentile among all CPUs in the benchmark database, with an average benchmark score of 28549.

Benchmark Performance

The Ryzen 5 PRO 5655G delivers strong multi-threaded results for its class. In Cinebench R23, the multicore score reaches 17249, while the single-core score is 2435. The R20 run shows 7244 multicore and 1022 single-core, and the older R15 test yields 1738 multicore and 245 single-core. These numbers indicate a well-balanced chip that holds its own in both lightly threaded and fully loaded scenarios.

Looking at PassMark results, the multithread score is 20282, with a single-thread score of 3250. Specialty workloads show varied strengths: floating point math scores 39093, integer math reaches 69377, and extended instructions hit 18192. Data compression is particularly strong at 258491, while data encryption scores 15711. Random string sorting produces 26832, and physics simulation scores 871. The find prime numbers test is notably lower at 57, suggesting this processor is less optimized for that specific prime-number calculation pattern.

The average benchmark score of 28549 places the 5655G in a tight cluster with its nearest rivals. Against the AMD Ryzen 7 PRO 6850HS, the delta is exactly 0%, meaning the two chips perform identically on average. The Intel Core i5-14400T also shows a 0% delta with an average score of 28537, a difference of just 12 points — effectively a tie. The Intel Xeon E-2436 scores 28536, again a 0% delta. The AMD EPYC 7203P is the only rival with a measurable difference, scoring 28583, which is 0.1% higher. These deltas are within noise for most workloads, so the 5655G is statistically tied with all four competitors on aggregate performance.

Platform and Compatibility

The Ryzen 5 PRO 5655G uses the AMD Socket AM4, a mature platform that supports DDR4 memory in dual-channel configuration, with a memory bandwidth of 51.2 GB/s. ECC memory is supported, which is a notable feature for users who prioritize data integrity in workstations or small servers. The processor provides PCIe Gen 3 with 16 lanes from the CPU, which is adequate for a single high-end graphics card or a fast NVMe drive, though it lacks the PCIe Gen 4 bandwidth of newer platforms.

The integrated graphics is Radeon Vega 7, making this a viable option for systems without a discrete GPU. The multiplier is locked, so overclocking via multiplier adjustment is not available, but the chip’s boost behavior is already well-tuned out of the box. The production status is Active, and the release date is May 6, 2024. The part number is 100-000001513. Upgrade path on AM4 is limited to other AM4 processors, but the platform’s maturity means BIOS support is broadly available across existing motherboards.

Who Should Consider It

This processor is a strong fit for productivity and mixed-use systems where multi-threaded performance matters. The Cinebench R23 multicore score of 17249 indicates solid rendering capability for occasional video editing or 3D modeling tasks. The PassMark multithread score of 20282 reinforces that impression, showing good throughput for compilation, batch processing, or running multiple virtual machines.

For gaming, the single-core performance is respectable — the Cinebench R23 single-core score of 2435 and PassMark single-thread score of 3250 are competitive with modern mid-range chips. Paired with a discrete GPU, this CPU will not bottleneck most games at standard resolutions. The integrated Radeon Vega 7 GPU provides a fallback for light gaming or office use without a dedicated card, though demanding titles will require a discrete solution.

Office and everyday workloads benefit from the high data compression score of 258491, which reflects snappy file archiving and database operations. The 6-core/12-thread configuration handles multitasking well, and the 65W TDP keeps cooling requirements modest — a capable air cooler suffices. Users who need ECC memory support in a desktop package will find this one of the few AM4 options with that feature, making it suitable for entry-level workstations or home lab servers.

How It Compares

Against the AMD Ryzen 7 PRO 6850HS, the 5655G is statistically identical, with a 0% delta in average score. Both chips deliver the same aggregate performance, but the 6850HS is a mobile processor, whereas the 5655G is desktop-oriented. In practice, the 5655G offers similar compute but with a desktop platform’s upgrade and cooling flexibility.

The Intel Core i5-14400T matches the 5655G within a rounding error — a 0% delta with only 12 points separating them. The i5-14400T has a lower TDP and different architecture, but benchmark results show no meaningful performance advantage either way. Users choosing between them should base the decision on platform preferences rather than raw speed.

The Intel Xeon E-2436 also sits at a 0% delta, scoring 28536 versus the 5655G’s 28549. This is a workstation-oriented chip, but the 5655G keeps pace in mixed workloads. The Xeon may offer additional platform features, but on pure compute, the 5655G is an equal performer.

The AMD EPYC 7203P is 0.1% faster, with an average score of 28583. This is a server-class processor, yet the delta is negligible — just 34 points. For most applications, the 5655G and the EPYC 7203P are interchangeable in performance, though the EPYC targets a very different market segment with higher core counts and server features.

Single-Thread vs Multi-Thread Behavior

The single-thread scores across Cinebench versions show a consistent pattern: R15 at 245, R20 at 1022, and R23 at 2435. These numbers indicate a strong per-core performance, thanks to the Zen 3 architecture and 4.40 GHz boost clock. The PassMark single-thread score of 3250 corroborates this, placing the chip in a range where everyday applications feel responsive.

Multi-thread performance scales well from the 6-core/12-thread design. The R23 multicore score of 17249 is roughly 7.1 times the single-core score, which is typical for a 6-core part with simultaneous multithreading. The PassMark multithread score of 20282 is about 6.2 times the single-thread score, showing good scaling efficiency. The data compression score of 258491 is particularly high relative to other PassMark sub-tests, indicating that the memory subsystem and cache hierarchy work well for data-intensive parallel tasks.

For real workloads, the split means this chip handles mixed usage gracefully. Single-threaded tasks like web browsing, office documents, and legacy applications run without lag, while multi-threaded tasks like video encoding, 3D rendering, and software compilation use the full 12 threads effectively. The lower find prime numbers score of 57 suggests that heavy number-theoretic calculations are not a strength, but such workloads are rare in general computing.
