AMD Ryzen 5 PRO 5655GE vs AMD Ryzen 7 5700 Comparison

The AMD Ryzen 5 PRO 5655GE and AMD Ryzen 7 5700 are both 5000-series desktop processors on the AM4 socket, but they occupy different corners of the market. The data shows a clean sweep: the Ryzen 7 5700 wins all 17 head-to-head benchmark comparisons, with margins ranging from a narrow 1.7% to a substantial 34.1%. The Ryzen 5 PRO 5655GE is not without merit, however, as it integrates Radeon Vega 7 graphics and supports ECC memory, making it a practical choice for specific professional or compact builds. The verdict is straightforward: if raw performance is the sole criterion, the Ryzen 7 5700 is the clear pick. If integrated graphics and ECC support are non-negotiable requirements, the Ryzen 5 PRO 5655GE becomes the only viable option in this pairing.

The Verdict

The data is unambiguous. The AMD Ryzen 7 5700 outperforms the AMD Ryzen 5 PRO 5655GE in every single benchmark recorded. For anyone building a system where CPU compute power is the priority, the Ryzen 7 5700 is the superior choice based on the benchmark results. Its 8 cores and 16 threads provide a decisive advantage in multi-threaded workloads, as evidenced by a 33.2% lead in Cinebench R23 multi-core (20655 vs 15504). Even in single-threaded tasks, it holds a lead, albeit a smaller one, with a 25% advantage in Cinebench R23 single-core (2916 vs 2188). The Ryzen 7 5700 also has an unlocked multiplier, allowing for overclocking, and carries a launch MSRP of $179.

Conversely, the Ryzen 5 PRO 5655GE is the pick for a specific set of users. It is the only one of the two with an integrated GPU, the Radeon Vega 7, which means a discrete graphics card is not required for a basic display output. It also supports ECC memory, a feature absent from the Ryzen 7 5700, making it suitable for entry-level servers or workstations where data integrity is critical. Its lower core count of 6 and 12 threads, combined with its lower benchmark scores, places it firmly behind the Ryzen 7 5700 in performance, but its feature set is unique to this comparison. If you need those specific features over maximum performance, the choice is clear.

Architecture Differences

Both processors are built on the same foundational architecture: Zen 3. They share the same 7 nm process node from TSMC, the same Cezanne codename, and identical transistor counts and die sizes (10,700 million transistors on a 180 mm² die). Both use the AMD Socket AM4 and support dual-channel DDR4 memory with a memory bandwidth of 51.2 GB/s. The core differences in architecture are not in the microarchitecture itself but in the configuration and feature set.

The Ryzen 7 5700 offers 8 cores and 16 threads, while the Ryzen 5 PRO 5655GE is limited to 6 cores and 12 threads. Both have a 16 MB L3 cache, and both have 64 KB of L1 and 512 KB of L2 cache per core. However, the Ryzen 5 PRO 5655GE integrates a Radeon Vega 7 graphics unit, which the Ryzen 7 5700 lacks entirely. This is a significant architectural difference for system builders, as it dictates whether a separate GPU is necessary. Furthermore, the Ryzen 5 PRO 5655GE supports ECC memory, a feature typically reserved for professional or server-oriented hardware, whereas the Ryzen 7 5700 does not list this as a supported feature. The PCIe configuration also differs, with the Ryzen 7 5700 offering Gen 3 with 20 lanes (CPU only) versus the Ryzen 5 PRO 5655GE's Gen 3 with 16 lanes (CPU only).

Where Each One Wins

Based on the 17 head-to-head benchmarks, the Ryzen 7 5700 wins in every category. There is no benchmark where the Ryzen 5 PRO 5655GE comes out ahead. The Ryzen 7 5700's strongest lead is in the PassMark physics test, where it is 34.1% faster (984 vs 648). It also shows dominant wins in data compression (316699 vs 228037, a 28% lead) and extended instructions (21945 vs 15714, a 28.4% lead). These results point to a processor that excels in heavily multi-threaded and compute-intensive tasks.

The Ryzen 5 PRO 5655GE's "win" is not in performance but in features. Its integrated Radeon Vega 7 graphics make it the only option here for a system without a discrete GPU. The ECC memory support is another significant advantage for specific professional workloads where memory errors are unacceptable. While it loses all performance benchmarks, it wins on platform flexibility and reliability features. The data shows its closest performance to the Ryzen 7 5700 is in the single-threaded PassMark test, where it trails by just 1.7% (3240 vs 3296), suggesting its single-core architecture is competitive, but its multi-core performance is severely hampered by having 2 fewer cores.

FAQ

Head-to-Head Benchmarks

The benchmark data paints a picture of consistent dominance for the Ryzen 7 5700. The largest single victory for the Ryzen 7 5700 is in the PassMark physics test. It scores 984 versus the Ryzen 5 PRO 5655GE's 648, a delta of 34.1%. This is a massive gap that highlights the advantage of having 8 cores versus 6 in a physics simulation workload.

The Cinebench R23 results are representative of the overall trend. In the multi-core test, the Ryzen 7 5700 scores 20655, which is 24.9% higher than the 15504 scored by the Ryzen 5 PRO 5655GE. Similarly, in the Cinebench R20 multi-core test, the Ryzen 7 5700 leads with 8675 points versus 6511, a 24.9% difference. The single-core results are equally one-sided, with the Ryzen 7 5700 leading by 25% in both Cinebench R15 (293 vs 220) and R23 (2916 vs 2188) single-core tests.

The closest contest is in the PassMark single-thread and singlethread tests, where the Ryzen 7 5700 scores 3296, only 1.7% ahead of the Ryzen 5 PRO 5655GE's 3240. This shows that clock-for-clock, the cores are very similar in single-threaded execution, but the Ryzen 7 5700's higher boost clock of 4.60 GHz versus 4.40 GHz gives it a marginal edge.

Beyond the physics test, other substantial wins for the Ryzen 7 5700 include a 28% lead in data compression (316699 vs 228037), a 27.8% lead in data encryption (20096 vs 14509), a 28.4% lead in extended instructions (21945 vs 15714), and a 28.3% lead in random string sorting (33138 vs 23769). These results consistently show the Ryzen 7 5700 delivering roughly a quarter to a third more performance in multi-threaded and data-intensive tasks. The Ryzen 5 PRO 5655GE is not superior in any recorded metric.

Specification Differences

The most critical specification difference is the core and thread count. The AMD Ryzen 7 5700 comes with 8 cores and 16 threads, while the AMD Ryzen 5 PRO 5655GE has 6 cores and 12 threads. This fundamental difference dictates the performance gap seen throughout the benchmarks.

Clock speeds also differ. The Ryzen 7 5700 has a base clock of 3.70 GHz and a boost clock of 4.60 GHz. The Ryzen 5 PRO 5655GE has a lower base clock of 3.40 GHz and a boost clock of 4.40 GHz. The Ryzen 7 5700 also has an unlocked multiplier, allowing for overclocking, whereas the Ryzen 5 PRO 5655GE is locked.

The integrated graphics and ECC memory support are the key differentiators in favor of the Ryzen 5 PRO 5655GE. It includes Radeon Vega 7 graphics and supports ECC memory, both of which are absent from the Ryzen 7 5700's specifications. Additionally, the Ryzen 7 5700 offers more PCIe lanes, with Gen 3, 20 Lanes (CPU only) compared to the Ryzen 5 PRO 5655GE's Gen 3, 16 Lanes (CPU only). Finally, the Ryzen 7 5700 has a launch MSRP of $179, while no launch MSRP is available for the Ryzen 5 PRO 5655GE.
