AMD EPYC 7H12 vs AMD Ryzen 3 PRO 5355GE Comparison

Head-to-Head Benchmarks

The benchmark data delivers an unambiguous verdict: the AMD EPYC 7H12 wins every single head-to-head comparison recorded in the database, across both multi-core and single-core workloads. The Ryzen 3 PRO 5355GE does not secure a single victory in any of the six head-to-head tests. The margin is consistent and striking, with every comparison showing the EPYC 7H12 ahead by 81.7%. This uniformity across tests with very different workloads indicates a fundamental performance gap rather than a workload-specific advantage.

In Cinebench R15 multi-core, the EPYC 7H12 scores 5965 against the Ryzen 3 PRO 5355GE's 1093. The single-core R15 test shows the same pattern: 842 for the EPYC against 154 for the Ryzen. Moving to Cinebench R20, the multi-core result is 24858 versus 4555, while the single-core result is 3509 versus 643. The Cinebench R23 results continue the trend: the EPYC posts 59188 in multi-core versus 10846, and 8355 in single-core versus 1531. The database records the delta at -81.7% for every one of these comparisons, meaning the Ryzen's scores are 81.7% lower than the EPYC's in each test. This is not a narrow margin; it is a dominant sweep.

The wider benchmark suite, which includes additional tests for the Ryzen 3 PRO 5355GE, helps contextualize its performance. The Ryzen's PassMark multi-thread score is 12761, its integer math score is 44665, and its floating point math score is 24115. However, these numbers do not change the head-to-head picture because the EPYC 7H12 was not recorded for those specific tests. The only directly comparable data points are the six Cinebench tests, and the EPYC wins all six. The average benchmark score in the database places the Ryzen at 17482 and the EPYC at 17120, a difference of roughly 2%, but that aggregate figure obscures the head-to-head reality. When measured directly against each other, the EPYC is decisively faster in every recorded test.

The percentile ranking offers another lens: both processors sit at the 71st percentile of all CPUs in the database. That shared percentile is a reminder that percentile is a broad measure of overall standing, not a head-to-head metric. The direct comparisons tell the sharper story. The EPYC 7H12 is the clear winner in every benchmark where both were measured.

Architecture Differences

The two processors come from different architectural generations. The Ryzen 3 PRO 5355GE is built on Zen 3, with the codename Cezanne, and belongs to the Ryzen 3 generation listed as Zen 3 (Cezanne). The AMD EPYC 7H12 is built on Zen 2, with the codename Rome, and belongs to the EPYC generation listed as Zen 2 (Rome). Both are manufactured by AMD at TSMC on a 7 nm process node, so the manufacturing process is identical, but the underlying architectures differ by one generation.

The transistor counts and die sizes differ substantially. The Ryzen 3 PRO 5355GE contains 10,700 million transistors on a die size of 180 mm². The AMD EPYC 7H12 contains 3,800 million transistors on a die size of 74 mm². These figures reflect different design approaches: the Ryzen is a monolithic desktop chip with integrated graphics, while the EPYC is a server chip built around a chiplet design, which the database reflects through its smaller per-die metrics.

Cache architecture also differs. The Ryzen 3 PRO 5355GE has 64 KB of L1 per core and 512 KB of L2 per core, with 8 MB of L3 cache. The AMD EPYC 7H12 has 96 KB of L1 per core and 512 KB of L2 per core, but its L3 cache is 256 MB and shared across the chip. The L3 difference is enormous: 8 MB versus 256 MB. The EPYC's larger shared cache is a defining feature for server workloads that benefit from massive data residency close to the cores.

The socket and platform targets reflect the architectural split. The Ryzen 3 PRO 5355GE uses AMD Socket AM4, a desktop platform, while the AMD EPYC 7H12 uses AMD Socket SP3, a server platform. PCIe support also differs: the Ryzen uses PCIe Gen 3 with 16 lanes (CPU only), while the EPYC uses PCIe Gen 4. The EPYC supports newer PCIe generation and is designed for a server motherboard ecosystem with far more expansion capability.

Specification Differences

The most obvious specification difference is core count. The Ryzen 3 PRO 5355GE has 4 cores and 8 threads, while the AMD EPYC 7H12 has 64 cores and 128 threads. This is a 16x difference in both cores and threads.

Clock speeds differ in the opposite direction. The Ryzen 3 PRO 5355GE has a base clock of 3.60 GHz and a boost clock of 4.20 GHz. The AMD EPYC 7H12 has a base clock of 2.60 GHz and a boost clock of 3.30 GHz. The Ryzen is clocked higher on both base and boost, but the EPYC compensates with far more cores.

Thermal design power (TDP) differs dramatically. The Ryzen 3 PRO 5355GE has a TDP of 35 watts, while the AMD EPYC 7H12 has a TDP of 280 watts. The EPYC draws substantially more power, consistent with its server-class core count.

Memory support shows a major difference. Both support DDR4, but the Ryzen 3 PRO 5355GE uses a dual-channel memory bus with 51.2 GB/s bandwidth, while the AMD EPYC 7H12 uses an eight-channel memory bus with 204.8 GB/s bandwidth. The EPYC offers four times the memory channels and four times the memory bandwidth.

Integrated graphics differ as well. The Ryzen 3 PRO 5355GE includes Radeon Vega 6 integrated graphics, while the AMD EPYC 7H12 has no integrated graphics. The Ryzen is a desktop APU, the EPYC is a server processor that relies on discrete or external graphics.

The market segment and release dates also differ. The Ryzen 3 PRO 5355GE is a desktop processor released on 2024-09-04, while the AMD EPYC 7H12 is a server/workstation processor released on 2019-09-17. Both are listed as Active in production status, and neither has a launch MSRP recorded in the database. Neither processor has an unlocked multiplier.

The Ryzen 3 PRO 5355GE has the part number 100-000001751, while the AMD EPYC 7H12 has the part number 100-000000055. The Ryzen belongs to the 5000 series, while the EPYC has no series listed.

The Verdict

The data points to one clear conclusion: the AMD EPYC 7H12 is the faster processor in every head-to-head benchmark recorded. It wins all six Cinebench comparisons, both single-core and multi-core, by a margin of 81.7% in each case. The Ryzen 3 PRO 5355GE does not win a single test. For anyone whose priority is raw benchmark performance, the EPYC 7H12 is the choice.

The Ryzen 3 PRO 5355GE has advantages in other specification areas: a much lower TDP of 35 watts versus 280 watts, a higher boost clock of 4.20 GHz versus 3.30 GHz, integrated Radeon Vega 6 graphics, and a newer release date of 2024-09-04 versus 2019-09-17. It also uses the AM4 socket, which is a desktop platform, versus the EPYC's SP3 server platform.

The EPYC 7H12 counters with a 64-core, 128-thread configuration, 256 MB of shared L3 cache, eight-channel memory with 204.8 GB/s bandwidth, and PCIe Gen 4 support. Its benchmark scores reflect the massive core advantage.

The verdict depends on the use case. The Ryzen 3 PRO 5355GE is a low-power desktop processor with integrated graphics, suitable for compact systems where power draw is a priority and the workload does not demand extreme multi-core throughput. The AMD EPYC 7H12 is a server processor built for heavy multi-threaded workloads, with the core count, cache, and memory bandwidth to match. The benchmarks show that the EPYC dominates in raw compute, but the Ryzen's lower power envelope and integrated graphics make it the practical desktop choice.

Where Each One Wins

The AMD EPYC 7H12 wins in every measured benchmark category. Multi-core workloads are its strongest domain: Cinebench R15 multi-core (5965 versus 1093), R20 multi-core (24858 versus 4555), and R23 multi-core (59188 versus 10846) all show the EPYC far ahead. Its 64 cores and 128 threads are the obvious drivers of this dominance.

Surprisingly, the EPYC also wins in single-core tests despite its lower clock speeds. The EPYC posts 842 in Cinebench R15 single-core versus the Ryzen's 154, 3509 in R20 single-core versus 643, and 8355 in R23 single-core versus 1531. The Ryzen has a higher boost clock (4.20 GHz versus 3.30 GHz), yet the EPYC still comes out ahead in single-threaded Cinebench tests. This suggests the EPYC's architecture and cache configuration provide a single-core advantage that the clock speed difference cannot overcome.

The Ryzen 3 PRO 5355GE wins in areas outside benchmark scores. Its TDP of 35 watts is a fraction of the EPYC's 280 watts, making it suitable for low-power desktop builds. Its integrated Radeon Vega 6 graphics mean the system does not require a discrete GPU for basic display output. Its 4-core, 8-thread configuration is sufficient for lighter desktop workloads, and its 51.2 GB/s dual-channel memory bandwidth is adequate for its class.

The EPYC 7H12 wins in server-oriented specifications: eight-channel memory at 204.8 GB/s, 256 MB of shared L3 cache, PCIe Gen 4, and the SP3 socket. These features, combined with its benchmark dominance, make it the clear choice for server and workstation deployments where throughput matters most. The Ryzen 3 PRO 5355GE is the choice for a desktop system where power efficiency, integrated graphics, and a mainstream socket take priority over raw compute performance.
