AMD Ryzen 3 PRO 5355GE vs Intel Core i5-11400 Comparison

The AMD Ryzen 3 PRO 5355GE and the Intel Core i5-11400 are both desktop processors aimed at similar mainstream usage, yet the benchmark data reveals a clear performance hierarchy. The Intel Core i5-11400 dominates in nearly every recorded workload, winning 15 of the 17 head-to-head comparisons, while the AMD Ryzen 3 PRO 5355GE secures only 2 wins, both in single-threaded PassMark tests. The database places both processors at the 71st percentile among all CPUs, indicating that despite their different architectures and core counts, they occupy a similar overall performance tier.

The Verdict

The Intel Core i5-11400 is the decisive choice for users prioritizing raw multi-threaded and compute-heavy performance. Its six cores and twelve threads provide a significant structural advantage over the Ryzen 3 PRO 5355GE's four cores and eight threads. In Cinebench R23 multicore, the Intel part scores 14132 versus 10846 for the AMD part, a 23.3% deficit for the latter. This pattern repeats across the board: PassMark multithread scores show 16690 for Intel versus 12761 for AMD, a 23.5% gap. The Intel processor also leads in data compression by 26.1%, extended instructions by 30.4%, and floating point math by 29.1%. For any workload that scales with cores, the i5-11400 is the superior part.

The AMD Ryzen 3 PRO 5355GE offers a narrower but distinct advantage in single-threaded PassMark testing, where it scores 3089 compared to the Intel's 2990, a 3.3% margin. However, this single win does not translate into a lead in any Cinebench single-core test, where the Intel part wins by 23% or more across R15, R20, and R23. The AMD processor also stands out for its efficiency profile: it carries a 35W TDP versus the Intel's 65W, and it supports ECC memory, a feature absent on the Intel part. The AMD chip is built on a 7nm process from TSMC with a 180 mm² die, while the Intel chip uses Intel's 14nm process with a larger 276 mm² die.

Buyers should select the Intel Core i5-11400 for general productivity, content creation, or any multi-threaded application where its 23% to 36% lead in compute benchmarks matters more than power draw. The AMD Ryzen 3 PRO 5355GE is the better fit for compact, low-power systems or environments requiring ECC memory, where its 35W TDP and memory support are decisive, and where the loss of roughly 23% multicore performance is acceptable. The data does not support choosing the AMD part for raw speed outside of its narrow single-thread PassMark win.

Architecture Differences

The AMD Ryzen 3 PRO 5355GE belongs to the 5000 series and uses the Zen 3 architecture under the codename Cezanne. It is manufactured on a 7nm process at TSMC with a die size of 180 mm² and contains 10,700 million transistors. The Intel Core i5-11400 is part of the Core 11th Gen family, built on the Rocket Lake architecture and codename, using Intel's 14nm process with a die size of 276 mm². The foundry and process node differences are substantial: TSMC's 7nm node offers a smaller transistor geometry than Intel's 14nm node, which is reflected in the die size disparity.

The cache hierarchies differ as well. The AMD part has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 8 MB of L3 cache. The Intel part has 80 KB of L1 cache per core, 512 KB of L2 cache per core, and 12 MB of shared L3 cache. The Intel processor's larger L3 cache and higher L1 per-core allocation may contribute to its strong performance in cache-sensitive workloads.

Both processors support DDR4 memory with a dual-channel memory bus and identical theoretical memory bandwidth of 51.2 GB/s. The AMD processor supports ECC memory, while the Intel processor does not. The AMD processor uses PCIe Gen 3 with 16 lanes from the CPU, while the Intel processor uses PCIe Gen 4 with 20 lanes from the CPU. The integrated graphics also differ: the AMD part uses Radeon Vega 6, and the Intel part uses UHD Graphics 730.

The production status of the two chips diverges. The AMD Ryzen 3 PRO 5355GE is marked as Active, with a release date in the database of 2024-09-04. The Intel Core i5-11400 is marked as End-of-life, with a release date of 2021-03-15. Neither processor has an unlocked multiplier, and both are desktop market segments.

The AMD base clock is listed at 3.60 GHz and boost clock at 4.20 GHz, whereas the Intel base clock is 2.60 GHz and boost clock is 4.40 GHz. The TDP values are 35W for the AMD and 65W for the Intel.

The socket types are incompatible: the AMD part uses AMD Socket AM4, and the Intel part uses Intel Socket 1200. The process node and foundry differ, with AMD on TSMC's 7nm and Intel on its own 14nm. The die size is 180 mm² for AMD and 276 mm² for Intel. The AMD part has 10,700 million transistors, while the Intel part has no transistor count listed in the database.

The cache configurations differ in L1 and L3. AMD provides 64 KB of L1 per core and 8 MB of L3, while Intel provides 80 KB of L1 per core and 12 MB of shared L3. Both have 512 KB of L2 per core. The memory support is identical in type (DDR4), bus (dual-channel), and bandwidth (51.2 GB/s), but ECC support is true for AMD and false for Intel. PCIe capability differs: AMD has Gen 3 with 16 lanes, Intel has Gen 4 with 20 lanes. The integrated graphics are Radeon Vega 6 for AMD and UHD Graphics 730 for Intel. The Intel part has a launch MSRP of $182, while the AMD part has no launch MSRP listed.

Head-to-Head Benchmarks

The Intel Core i5-11400 wins 15 of the 17 head-to-head benchmarks, with margins ranging from 6.8% to 36.7%. The largest Intel advantage appears in passmark_find_prime_numbers, where it scores 49 versus 31, a 36.7% lead. In passmark_extended_instructions, Intel leads 14901 to 10368, a 30.4% margin, and in passmark_physics, the lead is the same 30.4%, with scores of 793 versus 552. Floating point math shows Intel ahead by 29.1%, scoring 34004 versus 24115.

The Cinebench suite shows consistent Intel dominance. In Cinebench R15 multicore, Intel scores 1424 versus 1093, a 23.2% lead. R15 singlecore shows 200 versus 154, a 23% lead. R20 multicore is 5935 versus 4555, a 23.3% lead, and R20 singlecore is 837 versus 643, also a 23.2% lead. R23 multicore is 14132 versus 10846, a 23.3% lead, and R23 singlecore is 1995 versus 1531, a 23.3% lead. The consistency of the 23% margin across all Cinebench tests indicates a stable performance gap tied to the core count and clock architecture.

PassMark integer math shows Intel at 57601 versus AMD's 44665, a 22.5% lead. Data compression is 206952 versus 152885, a 26.1% lead. Data encryption is 10264 versus 9564, a smaller 6.8% lead. Random string sorting is 23974 versus 17255, a 28% lead. PassMark multithread is 16690 versus 12761, a 23.5% lead.

The AMD Ryzen 3 PRO 5355GE wins only the PassMark single-thread tests, scoring 3089 in both passmark_single_thread and passmark_singlethread, versus 2990 for Intel, a 3.3% margin each. These two wins are notable because the Intel part wins every Cinebench single-core test by 23% or more, showing that the AMD advantage is specific to the PassMark single-thread workload rather than a general single-core superiority.

The average benchmark scores place the AMD part at 17482 and the Intel part at 17067, meaning the AMD chip has a slightly higher average score despite losing most head-to-head tests. This is explained by the nearest rival data: the AMD Ryzen 3 PRO 5355GE sits within 0.9% of its closest rivals, with the AMD Ryzen 5 4600G at 17507 and the AMD Ryzen 3 8300GE at 17614. The Intel Core i5-11400 sits within 0.3% of its rivals, including the AMD Ryzen 5 3600 at 17035 and the AMD EPYC 7H12 at 17120. The 71st percentile ranking for both chips confirms they belong to the same performance class in the broader CPU landscape, even though the i5-11400 is the stronger part in nearly every direct comparison.
