AMD EPYC 7H12 vs AMD Ryzen 5 4600G Comparison

The AMD Ryzen 5 4600G and AMD EPYC 7H12 are both Zen 2 parts built on TSMC's 7 nm process, but they target very different segments. The Ryzen 5 4600G is a desktop APU with integrated graphics, while the EPYC 7H12 is a server processor with 64 cores. In the database's head-to-head benchmarks, the EPYC 7H12 wins all six shared Cinebench tests, yet both processors hold the same 71st percentile among all CPUs. This analysis examines the recorded data to see where each part excels and what the specification differences imply.

Where Each One Wins

In the six head-to-head Cinebench tests, the EPYC 7H12 wins every one. The Ryzen 5 4600G does not win any of these shared tests. However, the Ryzen's benchmark record includes 3DMark, Geekbench, and PassMark scores, which are not part of the head-to-head set, so its performance in those workloads cannot be directly compared here. The data therefore supports the EPYC for any Cinebench-based workload, while the Ryzen's strengths lie outside the compared tests, such as its integrated graphics and lower power envelope. Despite a higher boost clock (4.20 GHz vs 3.30 GHz), the Ryzen fails to take a single shared test, indicating that the EPYC's architectural advantages dominate in these specific benchmarks.

Architecture Differences

Both processors share the same Zen 2 architecture, 7 nm process, and TSMC foundry, but they diverge sharply in implementation. The Ryzen 5 4600G uses the Renoir codename and fits the AM4 socket, while the EPYC 7H12 uses the Rome codename and requires the SP3 socket. The EPYC packs 64 cores and 128 threads against the Ryzen's 6 cores and 12 threads. The EPYC also has a larger L1 cache (96 KB per core vs 64 KB) and a massive 256 MB shared L3 cache versus 8 MB. Memory support differs: the EPYC runs eight-channel DDR4 with 204.8 GB/s bandwidth, while the Ryzen uses dual-channel with 51.2 GB/s. The EPYC supports ECC memory, the Ryzen does not. PCIe generation also differs: the EPYC offers Gen 4, the Ryzen Gen 3 with 20 lanes. The EPYC has no integrated graphics, while the Ryzen includes Radeon Vega 7. The EPYC's TDP is 280 W, the Ryzen's 65 W. The EPYC is a server/workstation part, the Ryzen a desktop part. The Ryzen has an unlocked multiplier, the EPYC does not. The Ryzen's die size is 156 mm² with 9,800 million transistors, while the EPYC's is 74 mm² with 3,800 million transistors. The Ryzen launched on 2020-07-20, the EPYC on 2019-09-17.

Head-to-Head Benchmarks

The EPYC 7H12 leads by a consistent 77% margin across all six Cinebench tests. The deltas are -77% for multicore tests and -77.1% for some single-core tests, meaning the Ryzen trails by that percentage. The scores are as follows:

| Test | Ryzen 5 4600G | EPYC 7H12 | Delta (Ryzen) |

|------|---------------|-----------|---------------|

| Cinebench R15 multicore | 1370 | 5965 | -77% |

| Cinebench R15 singlecore | 193 | 842 | -77.1% |

| Cinebench R20 multicore | 5709 | 24858 | -77% |

| Cinebench R20 singlecore | 805 | 3509 | -77.1% |

| Cinebench R23 multicore | 13593 | 59188 | -77% |

| Cinebench R23 singlecore | 1919 | 8355 | -77% |

The EPYC's single-core advantage is particularly striking given its lower boost clock. In Cinebench R23 single-core, the EPYC scores 8,355 versus the Ryzen's 1,919, a 77% lead. This suggests that the EPYC's per-thread performance is substantially higher, likely due to architectural differences beyond clock speed. The multicore results are even more lopsided: the EPYC's 64 cores produce a 59,188 score in R23 multicore, while the Ryzen's 6 cores manage 13,593. The data shows no test where the Ryzen comes close to the EPYC.

The Verdict

The recorded data shows the EPYC 7H12 as the clear performance leader in every shared test, with a consistent 77% advantage. The Ryzen 5 4600G, however, offers features the EPYC lacks: integrated graphics, a lower 65 W TDP, an unlocked multiplier, and a desktop AM4 socket. The choice depends on whether the workload requires the EPYC's massive core count and memory bandwidth, or the Ryzen's integrated graphics and lower power envelope. For server or workstation compute tasks that rely on Cinebench-style rendering, the EPYC 7H12 is the only option that wins. For a desktop system where integrated graphics and a modest power draw are priorities, the Ryzen 5 4600G is the part to select. The data does not support any scenario where the Ryzen outperforms the EPYC in the compared benchmarks.
