AMD Ryzen 3 PRO 5355G vs AMD Ryzen 7 5800X3D Comparison

The Verdict

The AMD Ryzen 7 5800X3D is the clear performance leader in this comparison, winning all 11 head-to-head benchmark tests with decisive margins in nearly every category. The Ryzen 3 PRO 5355G, while competitive in single-thread performance, cannot match the 5800X3D in multi-threaded or compute-heavy workloads. The data shows a 101.7% advantage for the 5800X3D in PassMark multithread, meaning it more than doubles the Ryzen 3 PRO's score. For users prioritizing raw compute power, gaming, or content creation, the 5800X3D is the obvious choice. The Ryzen 3 PRO 5355G, however, offers integrated graphics, a lower 65W TDP, and an active production status, making it suitable for compact or power-conscious desktop builds where discrete graphics are not required.

Architecture Differences

Both processors are built on the Zen 3 architecture and use the 7 nm process node from TSMC, but their internal designs diverge significantly. The Ryzen 7 5800X3D carries the Vermeer codename, while the Ryzen 3 PRO 5355G uses Cezanne. The 5800X3D packs 8 cores and 16 threads, double the 4 cores and 8 threads of the 5355G. The transistor counts tell an interesting story: the 5355G has more transistors at 10,700 million versus 8,850 million for the 5800X3D, but the 5800X3D has a much smaller die size at 74 mm² compared to 180 mm². The L3 cache is the most striking difference, with the 5800X3D featuring 96 MB of shared L3 cache versus just 8 MB on the 5355G. Both share 64 KB L1 and 512 KB L2 per core. The 5800X3D supports PCIe Gen 4 with 20 lanes, while the 5355G is limited to PCIe Gen 3 with 16 lanes. The 5355G includes Radeon Vega 6 integrated graphics, whereas the 5800X3D has no integrated graphics solution. Both support DDR4 dual-channel memory with 51.2 GB/s bandwidth and ECC memory, and both are locked (multiplier not unlocked). The 5800X3D was released on 2022-04-19 and is end-of-life, while the 5355G came out on 2024-09-04 and remains active in production.

Head-to-Head Benchmarks

The 5800X3D dominates across every recorded test, but the magnitude of the wins varies hugely by workload. In passmark_find_prime_numbers, the 5800X3D scores 227 against 36, a 530.6% advantage, the largest delta in the entire comparison. This suggests the 8-core design with massive L3 cache excels at integer-heavy iterative tasks. Similarly, passmark_physics shows a 311.4% lead (2884 versus 701), indicating a strong advantage in physics simulation workloads.

The multithread test is another blowout: 28,309 versus 14,033, a 101.7% difference. The floating point math test follows with 50,100 versus 25,245, a 98.5% gap. Data encryption shows 20,258 versus 10,288, a 96.9% improvement, and data compression comes in at 329,688 versus 168,041, a 96.2% delta. Extended instructions show a 89.2% advantage (22,580 versus 11,935), and integer math is 93% higher (88,608 versus 45,910). Random string sorting is the smallest multi-threaded margin at 79.5% (33,776 versus 18,819).

The closest contest is in single-thread performance. PassMark single thread scores 3,234 for the 5800X3D versus 3,096 for the 5355G, a modest 4.5% lead. This narrow margin indicates that per-core efficiency is similar between the two, with the 5800X3D's higher boost clock of 4.50 GHz versus 4.20 GHz providing the edge. The 5355G actually has a higher base clock at 4.00 GHz versus 3.40 GHz, but the 5800X3D's superior boost capability and cache hierarchy win out.

Looking at the bigger picture, the 5800X3D records an average benchmark score of 27,896, placing it in the 80th percentile of all CPUs. Its nearest rivals include the AMD Ryzen 7 6800U (27,887, 0% delta), Intel Core i9-10900K (27,872, 0.1% delta), AMD Ryzen AI 5 PRO 340 (27,932, -0.1% delta), and Intel Core i5-12600KF (27,799, 0.3% delta). The 5355G averages 27,382, sitting in the 79th percentile. Its nearest rivals are the Intel Core i7-13700H (27,355, 0.1% delta), Intel Core Ultra 5 125H (27,507, -0.5% delta), AMD Ryzen 7 5800 (27,535, -0.6% delta), and Intel Core i5-12600K (27,578, -0.7% delta). Despite the massive head-to-head deltas, the average scores are surprisingly close because the benchmark suites include lighter workloads that narrow the gap. Still, the 5800X3D edges out in overall percentile ranking.

Where Each One Wins

The AMD Ryzen 7 5800X3D wins in every recorded benchmark category, but certain workloads show especially pronounced advantages. Prime number finding, physics simulation, and multithreaded tasks are where the 8-core, 16-thread design with 96 MB L3 cache shines brightest. The 530.6% lead in prime number tests and 311.4% lead in physics indicate this processor is well-suited for scientific computing, simulation, and heavily parallel integer workloads. The 101.7% multithread advantage and 98.5% floating point math lead make it the better choice for rendering, video encoding, and any workload that scales with core count. The 96.9% encryption advantage and 96.2% compression advantage suggest strong performance in data-intensive tasks like database operations, file archiving, and secure communications. The 5800X3D also holds the edge in gaming-adjacent workloads due to its massive L3 cache, though the database does not include specific gaming benchmarks. Its 80th percentile ranking versus the 5355G's 79th percentile reflects a slightly higher overall standing among all CPUs.

The AMD Ryzen 3 PRO 5355G has no benchmark wins in this comparison, but its advantages lie outside raw performance. It offers integrated Radeon Vega 6 graphics, making it a functional choice for systems without a discrete GPU. Its 65W TDP is significantly lower than the 5800X3D's 105W, which matters for compact builds with limited cooling or power budgets. The 5355G also has a higher base clock of 4.00 GHz versus 3.40 GHz, which helps in lightly threaded scenarios where boost clocks are not sustained. Its 4.5% single-thread deficit is small enough that everyday desktop responsiveness would feel similar. The 5355G's active production status means it remains available for new system builds, whereas the 5800X3D is end-of-life. Its smaller core count and 8 MB L3 cache make it less demanding on motherboard power delivery and cooling solutions, and its PCIe Gen 3 support is sufficient for many mainstream peripherals. For users who need a simple, power-efficient desktop processor with integrated graphics and do not require heavy multi-threaded compute, the 5355G is the practical option. For everyone else, the 5800X3D's benchmark dominance, particularly its 101.7% multithread lead and 96.2% compression advantage, makes it the clear performance pick.

The data indicates that while the two processors share the Zen 3 architecture and 7 nm process, they target very different market positions. The 5800X3D is a high-performance desktop part with 8 cores, 16 threads, and 96 MB of L3 cache, designed to maximize throughput in demanding applications. The 5355G is a 4-core, 8-thread PRO series part with integrated graphics and lower power consumption, aimed at business desktops and entry-level systems. The 5800X3D's 80th percentile ranking and average score of 27,896 place it alongside the Ryzen 7 6800U and Intel Core i9-10900K, while the 5355G's 27,382 average aligns it with the Intel Core i7-13700H and Core Ultra 5 125H. These nearest-rival comparisons confirm that the 5800X3D competes in a higher performance tier despite both chips carrying the AMD 5000 series label.
