AMD EPYC 7543 vs AMD Ryzen 5 4600H Comparison

Head-to-Head Benchmarks

The recorded data presents a decisive picture: the AMD EPYC 7543 wins every single head-to-head benchmark against the AMD Ryzen 5 4600H, and it does so by staggering margins. These are not close contests; they are generational and segment-defining gaps.

In Cinebench R15 multicore, the EPYC 7543 scores 5393 against the Ryzen 5 4600H's 1425. That is a 278.5% advantage. The EPYC's 32 cores and 64 threads simply overwhelm the Ryzen's 6 cores and 12 threads in any workload that scales across cores. The single-core R15 test tells a similar story, though with a different magnitude: the EPYC scores 761 versus the Ryzen's 176, a 332.4% delta. This is notable because single-core performance typically favors higher clock speeds, and the Ryzen 5 4600H has a higher boost clock (4.00 GHz) than the EPYC (3.70 GHz). Yet the EPYC's Zen 3 architecture, with its higher instructions per clock, still dominates.

The gap widens further in Cinebench R23. The EPYC 7543 posts 53509 in multicore, while the Ryzen 5 4600H manages only 8072. That delta is 562.9%, the largest margin in the entire head-to-head set. For single-core R23, the EPYC scores 7554 against the Ryzen's 1142.5, a 561.2% lead. These numbers suggest that the EPYC is not merely faster; it is operating in a different performance class entirely. The architecture difference, Zen 3 versus Zen 2, combined with the massive core count disparity, explains the breadth of this victory.

What is absent from the head-to-head data is any test where the Ryzen 5 4600H wins. The database records 4 wins for the EPYC 7543 and 0 wins for the Ryzen 5 4600H. This is a complete shutout.

The Verdict

The data points to an unambiguous conclusion: the AMD EPYC 7543 is the superior processor in every benchmark category recorded. Its 32 cores, 64 threads, and Zen 3 architecture deliver 278.5% to 562.9% higher scores in Cinebench tests compared to the Ryzen 5 4600H. The EPYC also holds a 69th percentile ranking among all CPUs, with an average benchmark score of 15477, while the Ryzen 5 4600H sits at the 70th percentile with an average score of 16341. Interestingly, the Ryzen has a higher average benchmark score overall, despite losing every head-to-head test. This is because the Ryzen's benchmark suite includes additional tests, such as 3DMark and PassMark, where the EPYC was not measured.

Who should pick which? The EPYC 7543, with its 256 MB of shared L3 cache, eight-channel DDR4 memory support, and 204.8 GB/s memory bandwidth, is designed for server and workstation workloads. The Ryzen 5 4600H, with its Radeon RX Vega 6 integrated graphics and 45 W TDP, targets mobile platforms. The recorded data shows that for pure compute performance in Cinebench, the EPYC is the clear choice. The Ryzen's only advantage lies in its portability and integrated graphics, which are not reflected in these benchmark scores.

Where Each One Wins

The head-to-head benchmark data shows the EPYC 7543 winning all four Cinebench tests: R15 multicore, R15 singlecore, R23 multicore, and R23 singlecore. The Ryzen 5 4600H has no wins in this dataset.

However, considering the full benchmark suites recorded for each processor, a nuanced picture emerges. The Ryzen 5 4600H has a substantial set of additional measurements, including 3DMark results (single thread: 675, 2 threads: 1325, 4 threads: 2543, 8 threads: 3767, 16 threads: 4387, max threads: 4355) and PassMark tests (multithread: 14228, single thread: 2418, integer math: 45698, floating point math: 26909, data compression: 202030, data encryption: 12217, extended instructions: 12942, find prime numbers: 28, physics: 629, random string sorting: 21689). The EPYC 7543 has no equivalent 3DMark or PassMark scores in the database, so direct comparison in those areas is impossible. The EPYC's wins are exclusively in Cinebench, which is a rendering benchmark. The Ryzen's wins, if any, would be in the absence of EPYC data, not in direct competition.

For use-case splits: the EPYC 7543 is the pick for multi-threaded rendering, video encoding, and server-side computation where Cinebench scores are indicative. The Ryzen 5 4600H, with its integrated Radeon RX Vega 6, is suited for mobile systems requiring basic graphics without a discrete GPU, though its Cinebench performance lags far behind.
