The Verdict

The data clearly favors the Ryzen 5 5500GT for almost all compute workloads. It wins 9 of 11 head-to-head tests, with margins ranging from 16.5% to 33.3% across multi-threaded and math-heavy tasks. The Ryzen 3 PRO 5355G’s only victories are in single-threaded performance, where it leads by a slim 1% (3096 versus 3066).

For users who prioritize multi-core throughput, video encoding, data compression, or encryption, the Ryzen 5 5500GT is the obvious pick. Its 6 cores and 12 threads, combined with 16 MB of L3 cache, deliver substantial gains in every parallel workload tested. The Ryzen 3 PRO 5355G, with 4 cores and 8 threads, is better suited for single-threaded responsiveness, but the margin is negligible.

The Ryzen 5 5500GT also offers an unlocked multiplier, making it the more flexible choice for users who plan to adjust clock speeds. However, the Ryzen 3 PRO 5355G holds a unique advantage in ECC memory support, which matters for specific stability-focused builds. Given the overall benchmark dominance, the Ryzen 5 5500GT is the recommended processor for general desktop use, while the Ryzen 3 PRO 5355G appeals to niche ECC requirements.

Head-to-Head Benchmarks

The largest win for the Ryzen 5 5500GT comes in the passmark_find_prime_numbers test, where it scores 54 versus 36, a 33.3% advantage. This result highlights the benefit of two additional cores in scalar integer work. Similarly, in passmark_floating_point_math, the Ryzen 5 scores 36694 against 25245, a 31.2% lead. Data compression shows a 31.1% gap (243904 versus 168041), and encryption follows at 30.3% (14754 versus 10288). Extended instructions land at 29.9% (17027 versus 11935), with integer math at 28.5% (64218 versus 45910).

The multi-threaded score, which serves as a general throughput indicator, shows the Ryzen 5 at 19000 versus 14033, a 26.1% advantage. Physics simulation comes in at 840 versus 701, a 16.5% lead, and random string sorting shows 24583 versus 18819, a 23.4% gap. The Ryzen 3 PRO 5355G counters in single-threaded tests, scoring 3096 versus 3066, a 1% edge that appears in both passmark_single_thread and passmark_singlethread.

These results indicate that the Ryzen 5 5500GT’s extra cores and larger cache translate into consistent, meaningful gains across every parallel workload. The Ryzen 3 PRO’s single-thread lead is narrow, suggesting that its higher base clock (4.00 GHz versus 3.60 GHz) provides only a marginal advantage in lightly threaded tasks.

Specification Differences

The two processors share several core specifications: both are 5000 series AMD chips with a 65 W TDP, use the AMD Socket AM4, and support DDR4 memory with a dual-channel bus and 51.2 GB/s bandwidth. Both also feature PCIe Gen 3 with 16 lanes (CPU only), and both are active production parts with a desktop market segment.

The key differences lie in core configuration and cache. The Ryzen 3 PRO 5355G has 4 cores and 8 threads, with an L3 cache of 8 MB. The Ryzen 5 5500GT has 6 cores and 12 threads, with an L3 cache of 16 MB. Both share the same L1 cache (64 KB per core) and L2 cache (512 KB per core).

Clock speeds differ as well: the Ryzen 3 PRO runs at 4.00 GHz base and 4.20 GHz boost, while the Ryzen 5 runs at 3.60 GHz base and 4.40 GHz boost. Memory support diverges on ECC: the Ryzen 3 PRO supports ECC memory, the Ryzen 5 does not. The multiplier is locked on the Ryzen 3 PRO but unlocked on the Ryzen 5. The integrated graphics also differ: the Ryzen 3 PRO features Radeon Vega 6, while the Ryzen 5 features Radeon Vega 7.

Release dates and part numbers vary: the Ryzen 3 PRO launched on 2024-09-04 with part number 100-000001749, while the Ryzen 5 launched on 2024-01-07 with part number 100-000001489. The Ryzen 5 has a launch MSRP of $125.

Architecture Differences

Both processors are built on the same Zen 3 architecture with the Cezanne codename, manufactured on a 7 nm process at TSMC. They share identical transistor counts (10,700 million) and die sizes (180 mm²), indicating that the silicon is fundamentally the same. The architecture generation is listed as Ryzen 3 (Zen 3 (Cezanne)) for the Ryzen 3 PRO and Ryzen 5 (Zen 3 (Cezanne)) for the Ryzen 5, reflecting the same underlying design.

The primary architectural difference is the core count: the Ryzen 5 5500GT enables 6 cores and 12 threads, while the Ryzen 3 PRO 5355G enables 4 cores and 8 threads. This is consistent with the L3 cache difference, where the Ryzen 5 has 16 MB versus the Ryzen 3 PRO’s 8 MB. The integrated graphics also scale with the core configuration, with the Ryzen 5 featuring Radeon Vega 7 (7 compute units) and the Ryzen 3 PRO featuring Radeon Vega 6 (6 compute units).

The memory controller differs on ECC support, with the Ryzen 3 PRO including ECC functionality while the Ryzen 5 omits it. The multiplier unlock status also differs, with the Ryzen 5 allowing overclocking while the Ryzen 3 PRO does not. These differences suggest that the Ryzen 3 PRO targets stability and data integrity, while the Ryzen 5 targets enthusiast flexibility and higher core counts.

Where Each One Wins

The Ryzen 5 5500GT wins decisively in all multi-threaded and compute-heavy workloads. The largest margins appear in prime number finding (33.3%), floating-point math (31.2%), and data compression (31.1%). It also leads in encryption (30.3%), extended instructions (29.9%), integer math (28.5%), multi-threaded throughput (26.1%), random string sorting (23.4%), and physics (16.5%). These results make it the choice for content creation, data processing, scientific computing, and any task that scales across cores.

The Ryzen 3 PRO 5355G wins only in single-threaded tests, with a 1% edge (3096 versus 3066). This advantage is small enough that it may not be noticeable in real-world applications, but it does indicate a slight edge in lightly threaded tasks such as legacy software, certain games, or quick response times. The Ryzen 3 PRO also offers ECC memory support, which is not reflected in benchmark scores but is a functional advantage for users who require error-correcting memory in professional or server-like environments.

For users who need maximum parallel performance, the Ryzen 5 5500GT is the clear winner. For users who value ECC support or a locked multiplier for stability assurance, the Ryzen 3 PRO 5355G fills a specific niche, despite its lower aggregate score. The data shows that the Ryzen 5’s extra cores and cache outweigh the Ryzen 3 PRO’s single-thread lead in nearly every measurable way.
