AMD Ryzen 3 PRO 5355GE vs AMD Ryzen 3 PRO 8300G Comparison

The AMD Ryzen 3 PRO 5355GE and AMD Ryzen 3 PRO 8300G are both 4-core, 8-thread desktop processors, yet benchmark results reveal they are tuned for distinctly different workloads. The 8300G dominates the majority of tests, winning 13 of 17 head-to-head comparisons, while the 5355GE claims four targeted victories. Both processors sit at the 71st percentile among all CPUs, and their average benchmark scores are remarkably close—17482 for the 5355GE versus 17278 for the 8300G—yet the distribution of wins tells a story of architectural priorities rather than overall parity.

Where Each One Wins

The AMD Ryzen 3 PRO 5355GE is the specialist in integer-heavy and data-processing tasks. Its most decisive win comes in PassMark integer math, where it scores 44665 against the 8300G’s 37292, a 19.8% advantage. It also leads in data encryption (9564 vs 8607, an 11.1% gap), floating-point math (24115 vs 23374, a 3.2% edge), and data compression (152885 vs 150567, a 1.5% margin). These wins are narrow in some cases, but they cluster around workloads that stress raw arithmetic throughput and cryptographic operations. The 5355GE appears optimized for legacy code paths and high-frequency integer loops, making it a reasonable choice for database-style processing or encryption-heavy tasks.

The AMD Ryzen 3 PRO 8300G, by contrast, is the general-purpose winner across rendering, physics, and single-threaded responsiveness. Its largest victory is in PassMark find prime numbers, where it scores 47 versus 31—a 34% lead. It also excels in PassMark physics (772 vs 552, a 28.5% advantage) and random string sorting (19703 vs 17255, a 12.4% lead). Across all Cinebench tests—R15, R20, and R23—the 8300G consistently outperforms by 12.2% in both single-core and multi-core scores. In single-thread PassMark, it leads 3550 to 3089, a 13% edge. For users running modern rendering engines, physics simulations, or productivity suites that rely on single-core speed, the 8300G is the clear choice.

Architecture Differences

The two processors belong to different generations and platforms. The 5355GE is part of the 5000 series, built on Zen 3 architecture with the Cezanne codename, while the 8300G is from the 8000 series, using Zen 4 with the Phoenix2 codename. The manufacturing process differs substantially: the 5355GE uses a 7 nm node from TSMC, whereas the 8300G uses a 4 nm node. Transistor counts reflect this: 10,700 million for the 5355GE versus 20,900 million for the 8300G, despite the latter having a smaller die size of 137 mm² compared to 180 mm². This density increase allows the Zen 4 chip to pack more functionality into less physical space.

Cache configurations also diverge. Both have 64 KB of L1 per core, but the L2 cache doubles from 512 KB per core on the 5355GE to 1 MB per core on the 8300G. L3 cache is 8 MB on both, though the 5355GE lists it as a flat 8 MB while the 8300G specifies it as 8 MB shared. Memory support differs entirely: the 5355GE uses DDR4 with a dual-channel bus and 51.2 GB/s bandwidth, while the 8300G uses DDR5 with dual-channel and 83.2 GB/s bandwidth. Both support ECC memory, but the PCIe interface differs—Gen 3 with 16 lanes on the 5355GE versus Gen 4 with 14 lanes on the 8300G. Integrated graphics also change: the 5355GE has Radeon Vega 6, while the 8300G features Radeon 740M.

Sockets and power envelopes separate the platforms further. The 5355GE runs on AMD Socket AM4 with a 35 W TDP, while the 8300G uses AM5 with a 65 W TDP. Base clocks are close—3.60 GHz for the 5355GE versus 3.40 GHz for the 8300G—but boost clocks favor the newer chip at 4.90 GHz versus 4.20 GHz. Neither processor has an unlocked multiplier, and both are listed as Active in production status.

Head-to-Head Benchmarks

The Cinebench suite shows a uniform pattern: the 8300G wins every test by exactly 12.2% in multi-core and 12% to 12.2% in single-core. In R15 multi-core, scores are 1245 versus 1093; in R20 multi-core, 5190 versus 4555; in R23 multi-core, 12359 versus 10846. Single-core results follow suit: R15 at 175 vs 154, R20 at 732 vs 643, R23 at 1744 vs 1531. This consistency suggests the 8300G’s higher boost clock and newer architecture translate directly into sustained performance gains across the board.

The PassMark suite paints a more mixed picture. The 8300G wins single-thread tests (3550 vs 3089, a 13% lead), multithread (13368 vs 12761, a 4.5% edge), extended instructions (11451 vs 10368, a 9.5% advantage), find prime numbers (47 vs 31, a 34% lead), physics (772 vs 552, a 28.5% margin), and random string sorting (19703 vs 17255, a 12.4% gap). Conversely, the 5355GE takes data compression (152885 vs 150567, a 1.5% win), data encryption (9564 vs 8607, an 11.1% win), floating-point math (24115 vs 23374, a 3.2% win), and integer math (44665 vs 37292, a 19.8% win). The largest single-test delta—34% in favor of the 8300G for prime number calculation—highlights the Zen 4’s strength in branch-heavy, integer-scalar workloads, while the 5355GE’s 19.8% integer math win shows it holds its own in sustained arithmetic streams.

The Verdict

Data favors the AMD Ryzen 3 PRO 8300G for most users. It wins 13 of 17 head-to-head tests, including all Cinebench workloads, and delivers a 34% lead in prime number calculation and a 28.5% lead in physics. Its single-thread performance is 13% higher, which translates into snappier application responsiveness. The 8300G also benefits from a newer 4 nm process, DDR5 memory with 83.2 GB/s bandwidth, and PCIe Gen 4 support. For rendering, physics, or general productivity, the 8300G is the stronger choice.

The AMD Ryzen 3 PRO 5355GE wins four specific tests, but its margins are narrower except in integer math (19.8%) and data encryption (11.1%). Its 35 W TDP is lower than the 8300G’s 65 W, and it uses DDR4, which may suit legacy AM4 platforms. For workloads dominated by integer math, encryption, or floating-point operations where the 5355GE leads by 3.2%, this chip remains viable. However, its overall average benchmark score of 17482 is nearly identical to the 8300G’s 17278, and its wins are in fewer, more specialized areas. Pick the 5355GE only if the specific integer or encryption advantages align with your workload; otherwise, the 8300G’s broader performance profile makes it the default choice.
