AMD EPYC 7742 vs AMD Ryzen 5 4600G Comparison

Head-to-Head Benchmarks

The benchmark data presents an unusually one-sided comparison. Across all six shared Cinebench tests, the AMD EPYC 7742 records a decisive victory over the AMD Ryzen 5 4600G, with no test going the other way. The margin is remarkably consistent, hovering just above 332% in every workload. In Cinebench R23 multi-core, the EPYC 7742 scores 58,769 against the Ryzen 5 4600G's 13,593, a 332.3% advantage. That same delta appears in Cinebench R15 multi-core, where the EPYC posts 5,923 versus 1,370, and in Cinebench R20 multi-core, with 24,682 against 5,709.

Single-core results tell a similar story, though the absolute numbers are smaller. The EPYC 7742 reaches 8,296 in Cinebench R23 single-core, while the Ryzen 5 4600G manages 1,919, a 332.3% lead. The pattern repeats in Cinebench R15 single-core (836 versus 193, 333.2%) and Cinebench R20 single-core (3,484 versus 805, 332.8%). The consistency of these margins across different Cinebench versions suggests the performance gap is structural rather than workload-specific, rooted in fundamental architectural differences between the two parts.

Looking at the broader database averages, the two CPUs sit surprisingly close in aggregate ranking. The EPYC 7742 holds a 70th percentile among all CPUs with an average benchmark score of 16,998, while the Ryzen 5 4600G lands at the 71st percentile with an average score of 17,507. This near-parity in overall standing, despite the massive Cinebench deltas, reflects the fact that the Ryzen 5 4600G brings a much wider suite of benchmark results to the table, including 3DMark and PassMark tests absent from the EPYC 7742's record. The EPYC's nearest rivals include the Intel Core i7-1260P at 17,007 (0.1% ahead), the AMD Ryzen 5 3600 at 17,035 (0.2% ahead), and the AMD EPYC 7702 at 16,932 (0.4% behind). The Ryzen 5 4600G's nearest rivals cluster similarly close, with the AMD Ryzen 3 PRO 5355GE at 17,482 (0.1% behind) and the Intel Core 7 150U at 17,395 (0.6% ahead).

Architecture Differences

Both processors share the same Zen 2 architecture and are fabricated on TSMC's 7 nm process, yet they diverge sharply in nearly every other design parameter. The EPYC 7742, codenamed Rome, belongs to the EPYC 7002 series and targets the server and workstation segment. It packs 64 cores and 128 threads into an AMD Socket SP3 package. The Ryzen 5 4600G, codenamed Renoir, is a desktop part on Socket AM4 with 6 cores and 12 threads. The core count difference, 64 versus 6, explains the multi-core benchmark dominance, but the architecture story runs deeper.

Cache hierarchies reveal part of the gap. The EPYC 7742 carries 96 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The Ryzen 5 4600G offers 64 KB of L1 per core, 512 KB of L2 per core, and only 8 MB of shared L3. That 256 MB versus 8 MB L3 disparity is among the largest in the database and directly impacts how much working set each chip can hold on-die. The EPYC's enormous cache pool suits server workloads with large, repeated data accesses, while the Ryzen's smaller cache reflects its desktop orientation.

Transistor counts and die sizes also differ substantially. The EPYC 7742 integrates 3,800 million transistors on a 74 mm² die, while the Ryzen 5 4600G packs 9,800 million transistors onto a 156 mm² die. The Ryzen's larger die and higher transistor count, despite far fewer cores, stem from its integrated Radeon Vega 7 graphics, which the EPYC 7742 lacks entirely. The Ryzen 5 4600G also features an unlocked multiplier, whereas the EPYC 7742 is locked.

Memory subsystems diverge as well. The EPYC 7742 supports DDR4 across an eight-channel memory bus with 204.8 GB/s of bandwidth and ECC memory support. The Ryzen 5 4600G uses a dual-channel DDR4 bus with 51.2 GB/s of bandwidth and no ECC support. PCIe generations differ: the EPYC 7742 runs Gen 4, while the Ryzen 5 4600G runs Gen 3 with 20 lanes available from the CPU. Clock speeds favor the Ryzen on paper, with a 3.70 GHz base and 4.20 GHz boost against the EPYC's 2.25 GHz base and 3.40 GHz boost, yet the EPYC's single-core Cinebench scores still more than quadruple the Ryzen's, indicating that core count and cache scale outweigh raw clock advantage in these tests.

The Verdict

The recorded data points to two entirely different purchasing contexts. The AMD EPYC 7742 wins all six head-to-head Cinebench comparisons by margins of roughly 332%, making it the clear choice for any workload that scales with core count, cache size, or memory bandwidth. Its 128 threads, 256 MB of L3 cache, and eight-channel memory architecture position it as a server-grade part built for sustained, parallel compute. The Ryzen 5 4600G, by contrast, offers integrated Radeon Vega 7 graphics, a lower 65 W TDP, and an unlocked multiplier, features the EPYC 7742 cannot match. The Ryzen's 3DMark results, including 4,863 in the 16-thread test and 4,889 at max threads, show it can handle threaded desktop workloads, but its Cinebench scores trail the EPYC by an order of magnitude.

The percentile rankings complicate a simple "one is better" conclusion. The EPYC 7742 sits at the 70th percentile while the Ryzen 5 4600G sits at the 71st, meaning the database as a whole considers them near-equal across all recorded benchmarks. This is because the Ryzen 5 4600G has a far larger benchmark footprint, including PassMark tests like data compression at 231,426 and integer math at 50,723, which pull its average up. The EPYC 7742's average score of 16,998 comes from a narrower set of Cinebench results, all of which are extremely high in absolute terms but cover less variety.

For a buyer choosing between these two, the decision hinges on workload type rather than overall performance tier. The EPYC 7742 dominates in rendering, scientific computing, and any parallel task that can exploit 128 threads and 256 MB of cache. The Ryzen 5 4600G serves desktop users who need integrated graphics, lower power draw, and overclocking flexibility. The data does not support calling one universally superior; it supports calling each superior in its designated role.

Specification Differences

The two processors differ across nearly every specification field in the database. Core count stands at 64 for the EPYC 7742 versus 6 for the Ryzen 5 4600G, with thread counts at 128 and 12 respectively. Base clocks are 2.25 GHz and 3.70 GHz, boost clocks 3.40 GHz and 4.20 GHz. TDP ratings are 225 W and 65 W. Sockets are AMD Socket SP3 and AMD Socket AM4. Codename and generation differ: Rome versus Renoir, EPYC (Zen 2 (Rome)) versus Ryzen 5 (Zen 2 (Renoir)). The process node is identical at 7 nm from TSMC, but transistor counts are 3,800 million versus 9,800 million, and die sizes are 74 mm² versus 156 mm².

Cache configurations diverge in L1 and L3. The EPYC 7742 has 96 KB of L1 per core and 256 MB of shared L3, while the Ryzen 5 4600G has 64 KB of L1 per core and 8 MB of shared L3. L2 is identical at 512 KB per core. Memory support is DDR4 for both, but the EPYC uses an eight-channel bus with 204.8 GB/s bandwidth and ECC support, while the Ryzen uses dual-channel with 51.2 GB/s and no ECC. PCIe is Gen 4 on the EPYC and Gen 3 with 20 CPU lanes on the Ryzen. The EPYC has no integrated graphics; the Ryzen includes Radeon Vega 7. The EPYC's multiplier is locked; the Ryzen's is unlocked. Release dates are 2019-08-06 for the EPYC and 2020-07-20 for the Ryzen. The Ryzen 5 4600G has a launch MSRP of $154; the EPYC 7742 has no recorded launch MSRP.
