AMD Ryzen 3 PRO 5355G vs AMD Ryzen 7 5700G Comparison

The Verdict

The data places the AMD Ryzen 7 5700G firmly ahead of the AMD Ryzen 3 PRO 5355G in every single benchmark recorded in the head-to-head comparison. The Ryzen 7 5700G wins all 11 tested workloads, with margins ranging from a modest 5.7% in single-threaded tasks to a dominant 50.8% in floating-point math. This is not a close contest; the Ryzen 7 5700G is the clear performance leader across the board.

However, the choice between these two processors depends entirely on workload priorities. The Ryzen 3 PRO 5355G, despite losing every benchmark, holds its own in specific niches. Its single-thread score of 3096 is only 5.7% behind the Ryzen 7 5700G's 3283, indicating that lightly-threaded applications will see near-parity. The Ryzen 3 PRO 5355G also carries an ECC memory support flag, a feature absent on the Ryzen 7 5700G, which appeals to users requiring data integrity in error-sensitive environments. Meanwhile, the Ryzen 7 5700G doubles the core count (8 vs 4) and threads (16 vs 8), and its benchmark scores reflect that scaling: it is roughly 74% faster in multithreaded PassMark (24419 vs 14033) and nearly 90% faster in integer math (91541 vs 45910).

For a buyer strictly prioritizing maximum throughput in multi-threaded workloads—rendering, encoding, compilation, or heavy scientific computing—the Ryzen 7 5700G is the obvious pick from the data. For a buyer needing a low-power, ECC-capable, single-thread-competent processor for a reliability-focused build, the Ryzen 3 PRO 5355G presents a defensible alternative, despite its lower absolute scores. The Ryzen 7 5700G also offers an unlocked multiplier (true for the 5700G, false for the 5355G), enabling overclocking headroom that the Ryzen 3 PRO lacks. In short: the Ryzen 7 5700G wins on raw performance; the Ryzen 3 PRO 5355G wins on ECC support and a single-thread deficit that is small enough to be imperceptible in many daily tasks.

Architecture Differences

Both processors are built on the same foundational architecture: Zen 3, codenamed Cezanne, manufactured on a 7 nm process at TSMC. They share identical transistor counts (10,700 million) and die size (180 mm²), indicating they are derived from the same silicon design. The key architectural divergence lies in core configuration and cache allocation. The Ryzen 7 5700G activates 8 cores, while the Ryzen 3 PRO 5355G activates only 4, which directly impacts the L3 cache size: the Ryzen 7 5700G has 16 MB, the Ryzen 3 PRO 5355G has 8 MB. Both have the same per-core L1 (64 KB) and L2 (512 KB) caches, but the total cache hierarchy scales with core count.

The integrated graphics differ as well: the Ryzen 3 PRO 5355G ships with Radeon Vega 6, while the Ryzen 7 5700G features Radeon Vega 8. This suggests the Ryzen 7 5700G has more graphics compute units, though the fact pack does not provide specific iGPU benchmark numbers. The memory support is identical—DDR4, dual-channel, 51.2 GB/s bandwidth—but ECC capability is exclusive to the Ryzen 3 PRO 5355G. The production status for both is Active, and both belong to the 5000 series, but the Ryzen 3 PRO 5355G was released later (September 2024) versus the Ryzen 7 5700G (April 2021).

The multiplier unlock status is a notable architectural feature difference: the Ryzen 7 5700G has an unlocked multiplier, allowing user overclocking, while the Ryzen 3 PRO 5355G does not. This means the Ryzen 7 5700G can potentially exceed its 4.60 GHz boost clock with manual tuning, whereas the Ryzen 3 PRO 5355G is locked to its 4.20 GHz boost. The PCIe configuration is identical (Gen 3, 16 lanes from CPU), and both use the same socket, making them drop-in compatible on AM4 boards, but the extra cores and cache on the Ryzen 7 5700G will show in workloads that scale with parallelism.

Specification Differences

The specification table reveals several divergences between the two parts. Core and thread counts are the most significant: 4 cores/8 threads on the Ryzen 3 PRO 5355G versus 8 cores/16 threads on the Ryzen 7 5700G. Base clocks differ slightly, with the Ryzen 3 PRO 5355G at 4.00 GHz and the Ryzen 7 5700G at 3.80 GHz, but the boost clock favors the Ryzen 7 5700G at 4.60 GHz versus 4.20 GHz. Both have a 65 W TDP, so power draw is identical on paper.

L3 cache is the next major difference: 8 MB on the Ryzen 3 PRO 5355G versus 16 MB on the Ryzen 7 5700G. Integrated graphics differ (Vega 6 vs Vega 8), and ECC memory support is true for the Ryzen 3 PRO 5355G but false for the Ryzen 7 5700G. The multiplier unlock status also differs (false vs true, respectively). Release dates are far apart: September 2024 for the Ryzen 3 PRO 5355G, April 2021 for the Ryzen 7 5700G. The part numbers differ (100-000001749 vs 100-000000263), and neither has a launch MSRP in the data. All other fields—socket, architecture, process node, foundry, transistors, die size, memory support, memory bus, memory bandwidth, PCIe, market segment, and production status—are identical between the two.

Head-to-Head Benchmarks

The head-to-head data is unambiguous: the Ryzen 7 5700G wins every single workload, but the margins vary widely. The smallest gap is in single-threaded performance (PassMark single_thread and singlethread, both scoring 3096 vs 3283), a delta of 5.7% in favor of the Ryzen 7 5700G. This indicates that per-core performance is close, and the Ryzen 3 PRO 5355G is not far behind in lightly-threaded tasks.

The largest margin is in floating-point math, where the Ryzen 7 5700G scores 51296 versus the Ryzen 3 PRO 5355G's 25245, a 50.8% advantage. Integer math shows a similar pattern: 91541 vs 45910, a 49.8% delta. Data compression also heavily favors the Ryzen 7 5700G (318262 vs 168041, 47.2% delta), and data encryption shows a 49.4% gap (20325 vs 10288). Extended instructions are 45.4% higher on the Ryzen 7 5700G (21847 vs 11935), and random string sorting is 43.6% higher (33384 vs 18819).

The multithreaded PassMark score reflects the core advantage: 24419 on the Ryzen 7 5700G versus 14033 on the Ryzen 3 PRO 5355G, a 42.5% delta. Physics scores are also higher on the Ryzen 7 5700G (999 vs 701, 29.8% delta), and prime number finding shows a 39% gap (59 vs 36). Across all 11 head-to-head tests, the Ryzen 7 5700G wins with an average delta of roughly 40%, but the single-thread test stands out as the only metric where the Ryzen 3 PRO 5355G remains competitive.

Where Each One Wins

The Ryzen 7 5700G wins in every benchmark category recorded, making it the default choice for any performance-oriented workload. Its biggest advantages are in multi-threaded and math-intensive tasks: floating-point math (50.8% ahead), integer math (49.8% ahead), and data encryption (49.4% ahead) show that it excels in scientific computing, financial modeling, and data processing. The compression and sorting benchmarks (47.2% and 43.6% ahead, respectively) indicate strong performance in file archiving and database operations. The multithreaded PassMark score (42.5% ahead) and physics score (29.8% ahead) confirm that rendering, simulations, and gaming physics will run noticeably faster. Additionally, the unlocked multiplier on the Ryzen 7 5700G allows for overclocking, potentially widening these gaps further.

The Ryzen 3 PRO 5355G wins in one specific domain: ECC memory support. This is a feature absent on the Ryzen 7 5700G, and for applications requiring error-correcting memory—such as file servers, ZFS-based storage systems, or long-running compute jobs where silent data corruption is unacceptable—the Ryzen 3 PRO 5355G is the only viable option in this comparison. Its single-thread deficit is also small enough (5.7%) that in daily desktop use, web browsing, office applications, or legacy single-threaded software, the difference will be negligible. The Ryzen 3 PRO 5355G also has a higher base clock (4.00 GHz vs 3.80 GHz), which may help in bursty workloads that do not sustain boost clocks. For users locked to a 65 W TDP budget, both chips are equal, but the Ryzen 3 PRO 5355G delivers its performance with fewer cores, potentially making it easier to cool in small form factor builds.

In summary: the Ryzen 7 5700G is the performance winner across the board, with the data showing 11 wins out of 11 head-to-head benchmarks. The Ryzen 3 PRO 5355G is the niche pick for ECC reliability and near-parity single-thread performance, but it cannot match the Ryzen 7 5700G in any multi-threaded or math-heavy workload. The choice is clear: choose the Ryzen 7 5700G for raw speed, choose the Ryzen 3 PRO 5355G only if ECC memory is a hard requirement.
