AMD Ryzen 5 5600X3D vs AMD Ryzen 5 PRO 5655GE Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear picture of two very different Zen 3 desktop parts. The AMD Ryzen 5 5600X3D dominates the head-to-head comparison, winning 13 of the 17 recorded benchmarks, while the AMD Ryzen 5 PRO 5655GE takes the remaining 4. The most dramatic gaps appear in specific workload categories, while the PRO chip manages narrow victories in a few math-heavy and single-threaded tests.

The 5600X3D's most decisive victory comes in PassMark's Physics test, where it scores 2453 against the 5655GE's 648, a delta of -73.6%. This is the single largest margin anywhere in the comparison, and it reflects the 5600X3D's substantial advantage in a workload that is highly sensitive to cache capacity. Similarly, in PassMark's Find Prime Numbers test, the 5600X3D scores 181 versus just 49 for the 5655GE, a -72.9% difference. Both results point to the same underlying strength: the 5600X3D's massive L3 cache.

Across the Cinebench suite, the 5600X3D is consistently ahead by a nearly identical margin. In Cinebench R15 Multicore, it scores 1875 against 1562, a -16.7% delta. The same -16.7% delta appears in Cinebench R15 Singlecore (264 vs 220), Cinebench R20 Multicore (7813 vs 6511), Cinebench R20 Singlecore (1102 vs 918), Cinebench R23 Multicore (18603 vs 15504), and Cinebench R23 Singlecore (2626 vs 2188). The uniformity of this margin across both single-threaded and multi-threaded Cinebench runs suggests a consistent per-core throughput advantage for the 5600X3D, likely stemming from its cache hierarchy rather than raw clock behavior, since both chips boost to 4.40 GHz.

PassMark Multithread continues the trend: the 5600X3D scores 21888 versus 18057, a -17.5% delta. In PassMark Data Compression, the 5600X3D scores 247365 against 228037, a -7.8% delta. PassMark Extended Instructions shows 17102 versus 15714, a -8.1% gap. PassMark Data Encryption favors the 5600X3D at 15170 versus 14509, a -4.4% delta, and PassMark Random String Sorting gives the 5600X3D 24597 against 23769, a -3.4% margin.

The 5655GE's wins are narrower but notable. In PassMark Integer Math, it scores 67582 against 65587, a 3% delta in its favor. PassMark Floating Point Math goes to the 5655GE at 38204 versus 37464, a 2% margin. In PassMark Single Thread, the 5655GE scores 3240 versus 3187, a 1.7% advantage, and the identical result appears under the PassMark Singlethread listing. These are modest wins, but they show that in certain integer, floating-point, and single-threaded scenarios, the PRO chip can edge out the cache-heavy 5600X3D.

Where Each One Wins

The 5600X3D is the clear winner for any workload that benefits from large, fast cache access. The Physics and Find Prime Numbers results, with deltas of -73.6% and -72.9% respectively, are the strongest indicators. Physics simulations and prime-number sieving both involve repeated access to moderately sized datasets, exactly the kind of pattern where the 5600X3D's 96 MB of shared L3 cache provides a massive advantage over the 5655GE's 16 MB. The Cinebench results also favor the 5600X3D across the board, making it the stronger choice for rendering and general CPU throughput.

The 5655GE wins in a narrower set of scenarios. Its PassMark Single Thread score of 3240 edges out the 5600X3D's 3187, a 1.7% delta, so lightly threaded tasks that rely on per-core efficiency can favor the PRO part. Its Integer Math win at 3% and Floating Point Math win at 2% suggest that pure arithmetic throughput, independent of cache behavior, is slightly stronger on the 5655GE. However, these are small margins compared to the 5600X3D's dominant wins. The overall average benchmark score reflects this split: the 5655GE sits at 25880 with a 78th percentile ranking, while the 5600X3D averages 25365 at the 77th percentile. Despite losing most head-to-head tests, the 5655GE actually holds a slightly higher average score and percentile, because the 5600X3D's huge wins in a few tests do not fully compensate for the 5655GE's narrower but more consistent performance profile across the full benchmark set.

Architecture Differences

Both processors are built on AMD's Zen 3 architecture and use TSMC's 7 nm process node, but they come from different dies with different design goals. The 5655GE is a Cezanne part with a die size of 180 mm² and 10,700 million transistors. The 5600X3D is a Vermeer part with a much smaller die at 74 mm², though the database does not list a transistor count for it. The Cezanne die integrates additional components, which explains its larger physical size, while the Vermeer die is a more compact compute-focused design.

The defining architectural difference is L3 cache. The 5655GE has 16 MB of L3 cache, while the 5600X3D carries 96 MB of shared L3 cache. That 80 MB difference is entirely responsible for the 5600X3D's dominant performance in cache-sensitive workloads like Physics and Find Prime Numbers. Both chips have 64 KB of L1 cache per core and 512 KB of L2 cache per core, and both run with 6 cores and 12 threads.

Base clocks differ slightly: the 5655GE runs at 3.40 GHz, the 5600X3D at 3.30 GHz. Both boost to 4.40 GHz. The 5655GE has a 65 W TDP, the 5600X3D a 105 W TDP. The higher TDP on the 5600X3D reflects the power required to keep that large cache array fed and the higher sustained performance in multi-threaded workloads.

The integrated graphics situation is a major split. The 5655GE includes Radeon Vega 7 integrated graphics, making it a complete package for systems without a discrete GPU. The 5600X3D has no integrated graphics at all, so it requires a separate graphics card. PCIe support also differs: the 5655GE offers Gen 3 with 16 CPU lanes, while the 5600X3D offers Gen 4 with 20 CPU lanes. That gives the 5600X3D both a newer PCIe generation and more lanes for expansion. Both support DDR4 memory in dual-channel configuration with 51.2 GB/s of bandwidth, and both support ECC memory.

The 5600X3D launched in 2023 at a launch MSRP of $229, while the 5655GE arrived later in 2024 and the database lists no launch MSRP for it. The 5600X3D is marked end-of-life in the database, while the 5655GE remains active in production. Neither chip has an unlocked multiplier. Both use the AMD Socket AM4.
