AMD Ryzen 3 PRO 5355G vs AMD Ryzen Embedded 9900X3D Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive performance gap between these two processors, but with an important caveat: only one of them has recorded benchmark scores in the database. The AMD Ryzen 3 PRO 5355G has complete PassMark results across ten tests, while the AMD Ryzen Embedded 9900X3D has no recorded benchmark scores at all. This means the head-to-head comparison is one-sided, and the 9900X3D's performance must be inferred from its architectural specifications rather than measured results.

For the Ryzen 3 PRO 5355G, the strongest results come from compute-heavy workloads. The PassMark data compression test shows a score of 168,041, which is the highest raw score in its benchmark suite. Data encryption produces 10,288 points, and extended instructions reach 11,935. Integer math scores 45,910, while floating point math delivers 25,245. Random string sorting achieves 18,819. The multithread score is 14,033, and the single-thread score is 3,096. The physics test records 701 points, and the find prime numbers test produces 36 points.

The average benchmark score for the 5355G is 27,382, placing it in the 79th percentile among all CPUs in the database. Its nearest rivals in the database include the Intel Core i7-13700H with an average score of 27,355 (a delta of 0.1%), the Intel Core Ultra 5 125H at 27,507 (delta of -0.5%), the AMD Ryzen 7 5800 at 27,535 (delta of -0.6%), and the Intel Core i5-12600K at 27,578 (delta of -0.7%). This places the 5355G essentially at parity with these four competitors, with deltas all within one percent.

Since the 9900X3D has no benchmark entries, the database records zero wins for it and zero wins for the 5355G in head-to-head tests. The comparison must therefore rest on what the specifications indicate about capability, particularly core count, clock speeds, cache, memory bandwidth, and PCIe generation. The 9900X3D offers 12 cores and 24 threads versus 4 cores and 8 threads for the 5355G, a threefold increase in both dimensions. The base clock of 4.40 GHz and boost clock of 5.50 GHz for the 9900X3D exceed the 4.00 GHz base and 4.20 GHz boost of the 5355G by 10% and 31% respectively.

Architecture Differences

The two processors come from different architectural generations and target different market segments. The Ryzen 3 PRO 5355G is built on Zen 3 architecture with the Cezanne codename, part of the 5000 series. It uses a 7 nm process node from TSMC, integrating 10,700 million transistors on a 180 mm² die. The Ryzen Embedded 9900X3D is a Zen 5 design with the Granite Ridge codename, part of the 9000 series, and uses a 4 nm process node from TSMC. It contains 16,630 million transistors across a dual-die configuration measuring 2x 70.6 mm².

Cache configurations differ substantially. The 5355G provides 64 KB of L1 cache per core, 512 KB of L2 per core, and 8 MB of L3 cache. The 9900X3D offers 80 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3 cache. The L3 cache difference is particularly significant: 128 MB versus 8 MB, a factor of 16. The 9900X3D name includes the X3D designation, which in the database is associated with 3D V-Cache technology, although the specific vCache3d field is null for both processors.

Memory support diverges by generation. The 5355G uses DDR4 memory with dual-channel configuration and a memory bandwidth of 51.2 GB/s. The 9900X3D uses DDR5 memory, also dual-channel, with a memory bandwidth of 89.6 GB/s. The bandwidth difference is 75% in favor of the 9900X3D. Both processors support ECC memory, which is notable for embedded and professional workloads.

PCIe connectivity also differs. The 5355G provides PCIe Gen 3 with 16 lanes from the CPU. The 9900X3D provides PCIe Gen 5 with 24 lanes from the CPU. This represents two generations of PCIe advancement and 50% more lanes for the 9900X3D.

Socket compatibility separates the platforms entirely. The 5355G uses AMD Socket AM4, while the 9900X3D uses AMD Socket AM5. The 5355G has a locked multiplier, while the 9900X3D has an unlocked multiplier, allowing overclocking on the newer platform.

The integrated graphics differ in naming: the 5355G includes Radeon Vega 6, while the 9900X3D includes Radeon Graphics. The database does not provide detailed specifications for either GPU, so the comparison stops at the naming level.

Thermal design power shows a large gap. The 5355G has a TDP of 65 watts, while the 9900X3D has a TDP of 120 watts. This is a difference of 55 watts, which implies a substantially larger cooling requirement for the 9900X3D.

The Verdict

The data presents a clear split between two very different product categories. The Ryzen 3 PRO 5355G is a mainstream desktop processor with measured performance data, while the Ryzen Embedded 9900X3D is a high-end embedded part with no benchmark scores in the database. The verdict must therefore distinguish between what is measured and what is inferred.

For workloads that rely on single-thread performance, the 5355G demonstrates a score of 3,096 in the PassMark single-thread test. The 9900X3D has a boost clock of 5.50 GHz versus 4.20 GHz for the 5355G, which strongly suggests superior single-thread capability, but no measured confirmation exists in the database.

For multithreaded workloads, the 9900X3D has a structural advantage: 12 cores and 24 threads versus 4 cores and 8 threads. The 5355G scores 14,033 in the multithread PassMark test. A threefold core advantage plus higher clocks would theoretically produce a substantially higher multithread score for the 9900X3D, but again, no data confirms this.

The 5355G is a known quantity. Its average benchmark score of 27,382 places it in the 79th percentile of all CPUs tracked in the database. Its nearest rivals, all within 0.7% of its average score, include mainstream desktop and mobile processors from Intel and AMD. This indicates that the 5355G performs at a competitive level for its segment.

The 9900X3D is an unknown quantity in terms of measured performance, but its specifications position it as a far more capable processor on paper. The 128 MB of L3 cache, 4 nm process, PCIe Gen 5, DDR5 memory, and 5.50 GHz boost clock all point to a processor designed for demanding embedded workloads rather than mainstream desktop use.

The recorded data shows that the 5355G has an active production status and a release date of 2024-09-04. The 9900X3D also has an active production status with a release date of 2025-10-06. Both are current products in the database.
