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

The AMD Ryzen 7 5700X and AMD Ryzen 3 PRO 5355G are both Zen 3 parts on Socket AM4, but they target opposite ends of the desktop spectrum. The 5700X is a high-core-count workhorse, while the PRO 5355G is a low-core, integrated-graphics office chip. Benchmark results show a complete sweep: the 5700X wins all 11 head-to-head tests, with margins ranging from a modest 9.3% in single-threaded work to a crushing 230.6% in prime-number finding. This is not a close contest, but the PRO 5355G still has a clear reason to exist in prebuilt systems.

Where Each One Wins

The AMD Ryzen 7 5700X wins every single benchmark category where both chips have data. Its largest advantages are in compute-heavy parallel workloads. The data shows a 102% lead in integer math and a 105.4% lead in floating-point math. This is the chip for multi-threaded rendering, compilation, and scientific computing. The 5700X also dominates memory-intensive tasks, with a 92.6% advantage in data compression and a 96.3% edge in data encryption. Its 8 cores and 16 threads simply overwhelm the 4-core, 8-thread PRO 5355G.

The AMD Ryzen 3 PRO 5355G, by contrast, has no benchmark wins against the 5700X. Its only competitive area is single-thread performance, where it trails by just 9.3% (3385 vs 3096 in PassMark single-thread). In the context of the broader market, both chips sit at the 79th percentile of all CPUs, meaning the PRO 5355G is not slow—it is just outclassed by the 5700X. The PRO 5355G’s real strength is not raw performance but its integrated Radeon Vega 6 graphics, which the 5700X entirely lacks. For a system that needs no discrete GPU, the PRO 5355G is the only option of the two.

Architecture Differences

Both chips use the Zen 3 architecture on TSMC’s 7 nm process, but they are fundamentally different dies. The 5700X is Vermeer, a 74 mm² chip with 4,150 million transistors, built for desktop performance. The PRO 5355G is Cezanne, a much larger 180 mm² die with 10,700 million transistors, because it integrates the Radeon Vega 6 GPU. That integrated graphics is the key architectural split: the 5700X has no iGPU, so it requires a separate graphics card, while the PRO 5355G is a complete APU solution.

Cache configurations differ sharply. The 5700X has 8 cores sharing 32 MB of L3 cache, while the PRO 5355G has 4 cores with only 8 MB of L3. Per-core L1 (64 KB) and L2 (512 KB) are identical. Both chips support DDR4 memory on a dual-channel bus with 51.2 GB/s bandwidth, and both support ECC memory. The PCIe situation favors the 5700X: it has Gen 4 with 20 CPU lanes, whereas the PRO 5355G is limited to Gen 3 with 16 lanes. The PRO 5355G also has a locked multiplier, while the 5700X is unlocked for overclocking. Both are 65 W TDP parts, but the 5700X boosts to 4.60 GHz from a 3.40 GHz base, while the PRO 5355G runs a tighter 4.00 GHz base to 4.20 GHz boost.

Head-to-Head Benchmarks

The single-thread results are the closest margin. In PassMark single-thread, the 5700X scores 3385 against 3096 for the PRO 5355G, a 9.3% advantage. This is notable because the PRO 5355G has a higher base clock (4.00 GHz vs 3.40 GHz) and nearly the same boost clock (4.20 GHz vs 4.60 GHz). The 5700X’s higher boost clock and larger L3 cache likely explain the edge. In real terms, this means everyday desktop responsiveness will be similar, but the 5700X still pulls ahead.

The multi-threaded gap is enormous. In PassMark multithread, the 5700X scores 26612 versus 14033, a 89.6% lead. This is almost exactly double, which mirrors the 2x core and thread count. The pattern repeats across all parallel workloads: floating-point math shows a 105.4% lead (51842 vs 25245), integer math shows a 102% lead (92749 vs 45910), and physics simulation shows a 90.7% lead (1337 vs 701). The most extreme result is PassMark find prime numbers, where the 5700X scores 119 against 36, a 230.6% advantage—this test scales almost perfectly with core count.

Memory and I/O workloads also favor the 5700X heavily. Data compression shows a 92.6% delta (323610 vs 168041), while data encryption shows a 96.3% delta (20198 vs 10288). Random string sorting is the smallest multi-threaded gap at 78.1% (33512 vs 18819), but still a decisive win. Extended instructions, which tests SIMD and crypto-style operations, shows an 82.3% lead (21755 vs 11935). Across all 11 head-to-head tests, the 5700X wins by an average of roughly 90% in multi-threaded tasks and 9.3% in single-threaded tasks.

FAQ

Q: Is the Ryzen 7 5700X always faster than the Ryzen 3 PRO 5355G?

A: Yes, in every benchmark where both have data. The 5700X wins all 11 head-to-head tests, with margins from 9.3% in single-thread to 230.6% in prime-number finding.

Q: Is the Ryzen 3 PRO 5355G unlocked for overclocking?

A: No. The PRO 5355G has a locked multiplier. The Ryzen 7 5700X is unlocked, allowing overclocking on supported boards.

Q: How do these chips compare to their closest rivals?

A: The 5700X has an average score of 27578, matching the Intel Core i5-12600K exactly (0% delta) and slightly beating the AMD Ryzen 7 5800 by 0.2%. The PRO 5355G has an average score of 27382, trailing the Intel Core i5-12600K by 0.7% and the AMD Ryzen 7 5800 by 0.6%.

The Verdict

The data is unambiguous: the Ryzen 7 5700X is the superior processor by every measurable performance metric. It doubles the core and thread count, offers 4x the L3 cache (32 MB vs 8 MB), has faster PCIe Gen 4 versus Gen 3, and wins every benchmark by at least 9.3%. Anyone building a desktop for multi-threaded productivity, content creation, or gaming with a discrete GPU should pick the 5700X without hesitation. Its 79th percentile ranking and average score of 27578 place it alongside the Intel Core i5-12600K and AMD Ryzen 7 5800, making it a strong mainstream choice.

The Ryzen 3 PRO 5355G is not a performance part—it is a practical part. Its only architectural advantage is the integrated Radeon Vega 6 GPU, which makes it suitable for office desktops, thin clients, or budget prebuilts where a discrete GPU is unnecessary. Its 79th percentile ranking is respectable, and its single-thread score of 3096 is only 9.3% behind the 5700X. But its 4-core design caps it at an average score of 27382, which is statistically tied with the Intel Core i7-13700H and just 0.5-0.7% behind the Intel Core Ultra 5 125H and AMD Ryzen 7 5800. The PRO 5355G should only be chosen when the iGPU is a requirement; otherwise, the 5700X is the clear pick.
