AMD Ryzen 5 PRO 5655G vs AMD Ryzen 7 5800 Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the AMD Ryzen 7 5800 wins every single head-to-head comparison in the database, 17 out of 17 tests. No test favors the AMD Ryzen 5 PRO 5655G. The margins vary significantly by workload, but the direction is consistent throughout.

In Cinebench rendering tests, the Ryzen 7 5800 holds a remarkably uniform advantage. Across Cinebench R15, R20, and R23, the multicore scores show the Ryzen 7 5800 leading by 21.4% in every instance. The scores tell the story: R15 multicore is 2212 versus 1738, R20 multicore is 9220 versus 7244, and R23 multicore is 21953 versus 17249. The single-core Cinebench results show a similar pattern, with the Ryzen 7 5800 ahead by 21.5% in R15 (312 versus 245) and 21.4% in both R20 (1301 versus 1022) and R23 (3099 versus 2435). These are not marginal differences; they represent a substantial performance gap across the entire rendering workload spectrum.

The PassMark suite reveals where the gap widens and narrows. The closest contest is in single-thread performance, where the Ryzen 7 5800 leads by only 4.5% (3393 versus 3241). This is the one area where the Ryzen 5 PRO 5655G nearly matches its rival, suggesting that per-core efficiency is comparable and the gap is driven primarily by core count and boost behavior. The largest gap appears in PassMark find prime numbers, where the Ryzen 7 5800 leads by 55.5% (110 versus 49). This workload is highly sensitive to integer throughput and cache hierarchy, and the Ryzen 7 5800's two extra cores and larger L3 cache produce a decisive advantage.

Other PassMark tests show substantial but less extreme margins. PassMark physics shows a 39.9% lead for the Ryzen 7 5800 (1141 versus 686). PassMark integer math is 27.2% higher (92843 versus 67561), while floating point math is 25.1% higher (51588 versus 38649). PassMark multithread is 25.9% ahead (25823 versus 19129), and PassMark data encryption is 23.8% ahead (20021 versus 15253). Random string sorting shows a 23.5% edge (32998 versus 25253), data compression is 19.2% higher (316429 versus 255608), and extended instructions are 15.7% ahead (21297 versus 17944).

The 3DMark results, recorded only for the Ryzen 7 5800 in the database, show 7181 for 16 threads, 7138 for max threads, 5692 for 8 threads, 3443 for 4 threads, 1795 for 2 threads, and 916 for single thread. These scores establish a baseline for that processor's threaded scaling behavior, but no comparison is possible since the Ryzen 5 PRO 5655G lacks corresponding entries.

The Verdict

From the recorded data, the AMD Ryzen 7 5800 is the clear performance choice. It wins every benchmark in the comparison, and in most tests the margin is substantial. The average benchmark score for the Ryzen 7 5800 is 27535, placing it in the 79th percentile of all CPUs in the database. The Ryzen 5 PRO 5655G has an average score of 28032, which places it in the 80th percentile. The average scores are close because the Ryzen 5 PRO 5655G's benchmark set includes scores from tests not shared with the Ryzen 7 5800, but in the direct head-to-head comparisons, the Ryzen 7 5800 is consistently faster.

The Ryzen 5 PRO 5655G's nearest rivals in the database include the AMD Ryzen 5 PRO 8500GE at 28054 (0.1% higher), the Intel Core i5-14500T at 28065 (0.1% higher), the Intel Core i9-12900H at 28003 (0.1% lower), and the AMD Ryzen AI 5 435 at 28128 (0.3% higher). The Ryzen 7 5800's nearest rivals include the Intel Core Ultra 5 125H at 27507 (0.1% higher), the Intel Core i5-12600K at 27578 (0.2% higher), the AMD Ryzen 7 5700X at 27578 (0.2% higher), and the AMD Ryzen 5 7600X at 27636 (0.4% higher). These comparisons show both processors sitting in similar competitive territory against external rivals, but the internal head-to-head favors the Ryzen 7 5800.

For users who prioritize raw compute throughput, especially in multithreaded workloads, the Ryzen 7 5800 is the justified selection. The Ryzen 5 PRO 5655G is only competitive in single-threaded performance, where its 4.5% deficit is modest. For any workload that scales across cores, the Ryzen 7 5800's two additional cores and larger cache deliver a decisive edge.

Architecture Differences

Both processors are built on the Zen 3 architecture and the 7 nm process node from TSMC, but they are distinct silicon designs. The Ryzen 5 PRO 5655G uses the Cezanne die, measuring 180 mm² with 10,700 million transistors. The Ryzen 7 5800 uses the Vermeer die, measuring 74 mm² with 4,150 million transistors. The Cezanne die is substantially larger because it integrates a Radeon Vega 7 graphics unit, which the Vermeer die lacks. The Ryzen 7 5800 has no integrated graphics, requiring a discrete GPU for display output.

Core and thread counts differ as expected: the Ryzen 5 PRO 5655G has 6 cores and 12 threads, while the Ryzen 7 5800 has 8 cores and 16 threads. The base clocks are 3.90 GHz for the Ryzen 5 PRO 5655G and 3.40 GHz for the Ryzen 7 5800, so the Ryzen 5800 starts lower but boosts higher at 4.40 GHz versus 4.60 GHz. The cache configuration is a notable difference. The Ryzen 5 PRO 5655G has 16 MB of L3 cache, while the Ryzen 7 5800 has 32 MB of shared L3 cache. Both processors have 64 KB of L1 cache per core and 512 KB of L2 cache per core.

PCI Express support differs in generation and lane count. The Ryzen 5 PRO 5655G supports PCIe Gen 3 with 16 lanes from the CPU, while the Ryzen 7 5800 supports PCIe Gen 4 with 20 lanes. This gives the Ryzen 7 5800 newer interconnect bandwidth and additional lanes for expansion devices. Memory support is similar: both use DDR4 with a dual-channel bus and 51.2 GB/s of memory bandwidth, and both support ECC memory.

The Ryzen 5 PRO 5655G has a locked multiplier, while the Ryzen 7 5800 has an unlocked multiplier. The Ryzen 5 PRO 5655G was released on 2024-05-06, while the Ryzen 7 5800 was released on 2021-01-11. Both are active production parts in the 5000 series, use the AMD Socket AM4, and have a 65 W TDP. The Ryzen 5 PRO 5655G carries part number 100-000001513, and the Ryzen 7 5800 carries part number 100-000000456.

Where Each One Wins

The AMD Ryzen 7 5800 is the winner for any workload that benefits from additional cores and threads. Rendering, video encoding, physics simulation, data compression, encryption, and integer-heavy computation all show significant advantages. The PassMark find prime numbers test shows the largest gap at 55.5%, highlighting the Ryzen 7 5800's strength in workloads that stress the CPU's computational pipeline and cache. The 3DMark results, available only for the Ryzen 7 5800, show strong threaded scaling from 916 in single thread to 7181 in 16 threads, indicating consistent performance growth across thread counts.

The Ryzen 5 PRO 5655G is the better fit for systems requiring integrated graphics. Its Radeon Vega 7 GPU means a discrete graphics card is unnecessary for basic display output, which is valuable for office systems, compact builds, or any configuration where a dedicated GPU is not warranted. It also has a lower base clock of 3.90 GHz versus 3.40 GHz, which helps it approach the Ryzen 7 5800 in single-threaded performance, trailing by only 4.5% in PassMark single thread. The Ryzen 5 PRO 5655G also uses PCIe Gen 3 rather than Gen 4, which is a generation behind but sufficient for many mainstream workloads.

For users who need maximum compute throughput and already have a discrete GPU, the Ryzen 7 5800 is the obvious choice. For users who value integrated graphics, a newer release date of 2024-05-06 versus 2021-01-11, and a lower base clock with comparable boost behavior in single-threaded tasks, the Ryzen 5 PRO 5655G has its place. The data does not support choosing the Ryzen 5 PRO 5655G for raw performance in any benchmark category, but its integrated GPU and smaller die make it a distinct product with different system requirements.
