AMD Ryzen 5 PRO 5655G vs AMD Ryzen 7 5700X Comparison

The Verdict

The recorded data splits this comparison into two very different stories depending on the benchmark generation. The AMD Ryzen 5 PRO 5655G wins the Cinebench R23 tests decisively, while the AMD Ryzen 7 5700X dominates nearly every other measured workload. The head-to-head table shows 13 wins for the Ryzen 7 5700X and only 2 for the Ryzen 5 PRO 5655G. That lopsided result points to the 5700X as the stronger all-around processor for multi-threaded productivity, content creation, and math-heavy tasks. The 5655G's two wins, however, are not minor: it leads by 30.8% in Cinebench R23 multi-core and by 62.4% in Cinebench R23 single-core. Those are enormous margins, but they stand alone against a wall of PassMark and Cinebench R15 victories for the 5700X.

For a buyer who prioritizes raw compute in compression, encryption, integer math, floating point math, prime number finding, physics simulation, or random string sorting, the Ryzen 7 5700X is the clear pick from the data. Its 8 cores and 16 threads translate into a 28.1% lead in PassMark multi-thread and a 48.7% lead in PassMark physics. The Ryzen 5 PRO 5655G, with 6 cores and 12 threads, is only competitive in the specific Cinebench R23 tests, which may reflect a different workload scaling pattern or benchmark version behavior. The 5700X also carries a higher average benchmark score of 27578 versus 28032 for the 5655G, though the 5655G actually holds a higher percentile rank at 80 versus 79. The database's overall average score favors the 5655G slightly, but the head-to-head wins are overwhelmingly on the 5700X side.

Architecture Differences

Both processors are built on the Zen 3 architecture and use the 7 nm process node from TSMC, but they come from different dies. The Ryzen 5 PRO 5655G uses the Cezanne codename with a die size of 180 mm² and 10,700 million transistors. The Ryzen 7 5700X uses the Vermeer codename with a much smaller die at 74 mm² and 4,150 million transistors. That difference is significant because the 5655G integrates graphics, which the 5700X lacks entirely. The 5655G includes Radeon Vega 7 integrated graphics, while the 5700X has no integrated graphics at all. This makes the 5655G a self-contained option for systems without a discrete GPU, while the 5700X requires an external graphics card.

Cache configurations also differ. The 5655G has 16 MB of L3 cache, while the 5700X has 32 MB of shared L3 cache. Both have the same per-core L1 and L2 cache sizes at 64 KB and 512 KB per core. The memory support is identical in type and bus: DDR4 with dual-channel and 51.2 GB/s bandwidth, and both support ECC memory. The PCIe interface differs, with the 5655G limited to Gen 3 with 16 lanes from the CPU, while the 5700X supports Gen 4 with 20 lanes from the CPU. The 5700X also has an unlocked multiplier, whereas the 5655G does not, meaning the 5700X can be overclocked while the 5655G cannot.

Clock speeds favor the 5700X in boost, at 4.60 GHz versus 4.40 GHz, but the 5655G has a higher base clock at 3.90 GHz versus 3.40 GHz. The 5700X was released earlier, in April 2022, while the 5655G arrived in May 2024. The 5700X carries a launch MSRP of $299, while the 5655G has no recorded launch MSRP in the database. Both are active production parts on the AMD Socket AM4 platform.

Where Each One Wins

The Ryzen 7 5700X wins in almost every category that involves sustained multi-threaded throughput or heavy numeric computation. PassMark integer math shows a 27.2% lead, floating point math a 25.4% lead, and data compression a 21% lead. Data encryption is 24.5% faster on the 5700X, extended instructions are 17.5% faster, and random string sorting is 24.6% faster. The largest single margin is in prime number finding, where the 5700X scores 119 versus 49, a 58.8% advantage. Physics simulation also heavily favors the 5700X at 48.7% ahead. The 5700X also leads in Cinebench R15 multi-core by 25.4% and single-core by 3.2%.

The Ryzen 5 PRO 5655G wins only the two Cinebench R23 tests. Its single-core score of 2435 versus the 5700X's 1499 represents a 62.4% advantage, and its multi-core score of 17249 versus 13184 is a 30.8% lead. These results are surprising given that the 5700X has more cores and a higher boost clock. The data suggests that the Cinebench R23 workload, as recorded in this database, behaves differently from the other benchmarks, possibly due to different instruction paths or thermal behavior, but the exact cause is not stated. Outside of those two tests, the 5655G does not come close to the 5700X in any other recorded measurement.

For use cases like video encoding, 3D rendering, or scientific computing that rely on integer and floating point throughput, the 5700X is the obvious choice based on PassMark results. For single-threaded responsiveness in applications that are not heavily parallelized, the 5655G shows a strong edge in Cinebench R23 single-core, yet it still trails in PassMark single-thread by 4.3%. The 5655G's integrated graphics make it suitable for office or light media systems without a discrete GPU, while the 5700X is better for a dedicated workstation or gaming rig with a separate graphics card.

Head-to-Head Benchmarks

The Cinebench R23 results are the most striking outliers. The Ryzen 5 PRO 5655G scores 17249 in multi-core, which is 30.8% ahead of the Ryzen 7 5700X's 13184. In single-core, the 5655G scores 2435 versus 1499, a 62.4% lead. These two wins are the only ones for the 5655G, yet they are so large that they skew the overall average benchmark score in favor of the 5655G. The database's average benchmark score is 28032 for the 5655G and 27578 for the 5700X, a difference of only 454 points, but the percentile ranks are nearly identical at 80 and 79 respectively.

Outside of Cinebench R23, the Ryzen 7 5700X is consistently ahead. In Cinebench R15 multi-core, the 5700X scores 2329 versus 1738, a 25.4% win. Single-core R15 is closer, 253 versus 245, a modest 3.2% lead for the 5700X. PassMark multi-thread shows the 5700X at 26612 versus 19129, a 28.1% advantage. The physics test is particularly lopsided: 1337 versus 686, a 48.7% margin. Prime number finding is even more extreme at 119 versus 49, a 58.8% gap.

The PassMark math workloads all favor the 5700X by roughly a quarter. Integer math is 92749 versus 67561, a 27.2% lead. Floating point math is 51842 versus 38649, a 25.4% lead. Data compression is 323610 versus 255608, a 21% lead. Data encryption is 20198 versus 15253, a 24.5% lead. Extended instructions are 21755 versus 17944, a 17.5% lead. Random string sorting is 33512 versus 25253, a 24.6% lead. PassMark single-thread is the closest non-R23 result, with the 5700X at 3385 versus 3241, only a 4.3% difference.

These numbers tell a coherent story: the 5700X is the stronger processor for almost any compute-intensive task, with margins ranging from 3.2% to 58.8%. The 5655G's Cinebench R23 wins are anomalous in this dataset, but they are not trivial. A 62.4% single-core lead over a higher-boost 8-core part suggests that the 5655G's Cezanne design, with its larger die and integrated graphics, may have a different cache or memory hierarchy behavior in that specific benchmark. The data does not explain why, but the result is recorded.

Both processors share the same socket, architecture, process node, foundry, memory type, memory bus, memory bandwidth, ECC support, TDP of 65, and market segment as desktop parts. The differences are concentrated in core count, cache size, PCIe generation, integrated graphics presence, overclocking capability, and physical die characteristics. The 5700X is the larger core count part with more cache and newer PCIe, while the 5655G is a smaller core count part with integrated graphics and a later release date.
