AMD EPYC 7742 vs AMD Ryzen 3 PRO 5355GE Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the AMD EPYC 7742 wins all six recorded head-to-head comparisons against the AMD Ryzen 3 PRO 5355GE. The margins are consistent and massive, with every single test showing a delta of approximately 441.8% to 442.9% in favor of the EPYC part.

In Cinebench R15 multi-core, the EPYC 7742 scores 5923 against 1093 for the Ryzen 3 PRO 5355GE, a 441.9% advantage. The single-core result in the same test shows 836 versus 154, a 442.9% lead. Moving to Cinebench R20, the multi-core gap remains at 441.9% (24682 versus 4555), while single-core shows 3484 versus 643, a 441.8% difference. Cinebench R23 continues the pattern: multi-core 58769 versus 10846 (441.8%) and single-core 8296 versus 1531 (441.9%).

What stands out is the consistency of the margin. Whether the workload is single-threaded or multi-threaded, the EPYC 7742 holds roughly the same proportional advantage. This suggests the performance gap is not merely a core-count effect but reflects a fundamental difference in how each processor delivers its peak results under these specific benchmark conditions.

The Ryzen 3 PRO 5355GE does have additional PassMark records in the database, but these have no direct head-to-head counterpart for the EPYC 7742. In those standalone measurements, the Ryzen 3 PRO 5355GE records a PassMark single-thread score of 3089 and a multithread score of 12761. The data compression test shows 152885, data encryption 9564, extended instructions 10368, find prime numbers 31, floating point math 24115, integer math 44665, physics 552, and random string sorting 17255. These figures provide context for the Ryzen part's capabilities, but they do not change the outcome of the direct comparisons, where the EPYC 7742 is the clear winner in every recorded test.

The average benchmark score for the EPYC 7742 sits at 16998, placing it in the 70th percentile of all CPUs in the database. The Ryzen 3 PRO 5355GE averages 17482, putting it in the 71st percentile. These overall averages are close, which is notable given the extreme disparity in the Cinebench head-to-head results. The explanation lies in the different benchmark suites each processor has been subjected to, as the two parts do not share the same complete set of recorded tests.

Architecture Differences

The two processors come from different architectural generations and target entirely different market segments. The EPYC 7742 belongs to the EPYC 7002 series, uses the Zen 2 architecture with the codename Rome, and is built for the server and workstation segment on AMD Socket SP3. The Ryzen 3 PRO 5355GE belongs to the 5000 series, uses the Zen 3 architecture with the codename Cezanne, and is a desktop part on AMD Socket AM4.

Both are manufactured by AMD on a 7 nm process at TSMC, but the transistor counts differ substantially. The EPYC 7742 has 3,800 million transistors on a 74 mm² die, while the Ryzen 3 PRO 5355GE has 10,700 million transistors on a 180 mm² die. The Ryzen part packs more transistors into a larger die, reflecting its newer architecture and integrated graphics.

Core and thread counts are the most obvious differentiator. The EPYC 7742 offers 64 cores and 128 threads, while the Ryzen 3 PRO 5355GE offers 4 cores and 8 threads. Base clocks are 2.25 GHz for the EPYC and 3.60 GHz for the Ryzen. Boost clocks are 3.40 GHz versus 4.20 GHz respectively. The Ryzen part has the higher clock speeds, but the EPYC part has sixteen times the core count.

Cache configurations also diverge sharply. The EPYC 7742 has 96 KB of L1 per core, 512 KB of L2 per core, and 256 MB of shared L3 cache. The Ryzen 3 PRO 5355GE has 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of L3 cache. The EPYC's 256 MB shared L3 is a server-class feature designed to keep massive datasets close to the cores.

Memory support shows the same pattern. Both support DDR4 and ECC memory, but the EPYC 7742 uses an eight-channel memory bus with 204.8 GB/s of bandwidth, while the Ryzen 3 PRO 5355GE uses a dual-channel bus with 51.2 GB/s. PCIe generations differ as well: the EPYC supports Gen 4, while the Ryzen part supports Gen 3 with 16 lanes from the CPU only.

The Ryzen 3 PRO 5355GE includes integrated Radeon Vega 6 graphics, while the EPYC 7742 has no integrated graphics. The EPYC also has a locked multiplier, as does the Ryzen part, so neither offers overclocking via unlocked multipliers.

Release dates are far apart. The EPYC 7742 was released on 2019-08-06, while the Ryzen 3 PRO 5355GE was released on 2024-09-04. Both remain in active production status. The EPYC 7742 has a TDP of 225, while the Ryzen 3 PRO 5355GE has a TDP of 35, but the exact wattage figures are recorded in the database without further commentary.

Where Each One Wins

The EPYC 7742 wins every recorded head-to-head benchmark, making its case straightforward. In all six Cinebench tests, spanning R15, R20, and R23 and covering both single-core and multi-core workloads, the EPYC 7742 dominates by roughly 441.8% to 442.9%. This makes it the clear choice for any workload that can leverage its 64 cores and 128 threads, particularly multi-threaded rendering, scientific computing, and server-side processing where the 256 MB L3 cache and eight-channel memory bandwidth come into play.

The Ryzen 3 PRO 5355GE does not win a single direct comparison in the recorded data. However, its standalone PassMark results show strengths in specific areas. The single-thread score of 3089 indicates capable single-threaded performance, and the data compression score of 152885 is substantial. The floating point math score of 24115 and integer math score of 44665 show respectable throughput for a 4-core part. The integrated Radeon Vega 6 graphics mean the Ryzen part can operate in systems without a discrete GPU, which is relevant for compact desktop builds and office machines.

The data suggests the Ryzen 3 PRO 5355GE is suited for desktop scenarios where the 35 TDP, integrated graphics, and newer Zen 3 architecture matter more than raw core counts. Its 4.20 GHz boost clock is higher than the EPYC's 3.40 GHz, which can benefit lightly threaded applications. The EPYC 7742, by contrast, is a server and workstation processor where the 64-core count, 128 threads, and enormous cache are the primary assets.

The Verdict

The recorded data leads to a clear conclusion. The AMD EPYC 7742 is the dominant processor in every direct benchmark comparison, winning all six head-to-head tests with margins around 441.8% to 442.9%. Its 64 cores, 128 threads, 256 MB shared L3 cache, and 204.8 GB/s memory bandwidth make it the appropriate choice for server and workstation workloads where multi-threaded throughput is the priority. Its 70th percentile ranking and average benchmark score of 16998 place it among capable server parts, with nearest rivals including the Intel Core i7-1260P and AMD Ryzen 5 3600.

The AMD Ryzen 3 PRO 5355GE, despite losing every direct comparison, serves a different purpose. Its 4 cores and 8 threads, 4.20 GHz boost clock, integrated Radeon Vega 6 graphics, and 35 TDP make it suitable for desktop systems where power efficiency, integrated graphics, and a modern Zen 3 architecture are valued. Its 71st percentile ranking and average benchmark score of 17482 show that it holds its own against its own nearest rivals, including the AMD Ryzen 5 4600G and Intel Core 7 150U.

The choice between these two processors depends entirely on the intended use case. The EPYC 7742 is for massive parallel workloads and server deployments. The Ryzen 3 PRO 5355GE is for compact, efficient desktop builds. Neither part is a substitute for the other. The data does not support any scenario where the Ryzen 3 PRO 5355GE outperforms the EPYC 7742 in the recorded benchmarks, but the Ryzen part's existence is justified by its standalone PassMark results and its architectural advantages in clock speed, transistor count, and integrated graphics.
