AMD EPYC 74F3 vs AMD EPYC 7543 Comparison

Where Each One Wins

The benchmark data presents an unambiguous picture: the AMD EPYC 7543 wins every single recorded benchmark in the head-to-head comparison. Across all six Cinebench tests, spanning R15, R20, and R23 in both single-core and multi-core workloads, the EPYC 7543 holds a consistent 3.8% advantage over the EPYC 74F3. This is not a case of one chip dominating in threaded applications while the other takes single-threaded honors; the EPYC 7543 leads in both categories by the exact same margin.

The consistency of that 3.8% delta across every test is notable. In Cinebench R15 multicore, the EPYC 7543 scores 5393 against 5197 for the EPYC 74F3. The single-core R15 result shows 761 versus 733. Moving to R20, the multicore scores are 22473 and 21657, while single-core comes in at 3172 and 3057. In R23, the multicore result is 53509 versus 51566, and single-core is 7554 versus 7279. Every test, same relative gap.

The EPYC 7543 has 32 cores and 64 threads, while the EPYC 74F3 has 24 cores and 48 threads. That core count difference would normally suggest a larger multicore advantage for the 32-core part, but the EPYC 74F3 compensates with a higher boost clock. The EPYC 74F3 boosts to 4.00 GHz, while the EPYC 7543 tops out at 3.70 GHz. The result is that the EPYC 7543 still wins multicore workloads, but by a narrower margin than the raw core count might imply, and the EPYC 74F3 cannot convert its clock speed advantage into a single-core win either.

The average benchmark score tells a similar story. The EPYC 7543 posts an average score of 15477, while the EPYC 74F3 averages 14915. Both processors sit at the 69th percentile among all CPUs in the database. Looking at their nearest rivals, the EPYC 7543 sits close to the Intel Core 5 211TE, which averages 15370, a 0.7% difference. The EPYC 74F3 is closely matched with the Intel Core i7-9750H at 14886, a 0.2% difference. These proximity data points confirm that both chips occupy a similar performance tier overall, despite the EPYC 7543's consistent edge in the direct comparison.

For use-case planning, the data indicates that the EPYC 7543 is the stronger choice for any workload captured by these Cinebench tests. There is no benchmark category in the recorded data where the EPYC 74F3 takes the lead. The EPYC 74F3 does have a higher boost clock, which could matter in scenarios not covered by these particular tests, but within the measured benchmarks, the EPYC 7543 wins across the board.

The Verdict

The verdict is straightforward: the AMD EPYC 7543 is the better-performing processor according to the recorded benchmark data. It wins all six head-to-head comparisons, with a uniform 3.8% margin in each test. The EPYC 7543 also has a higher average benchmark score at 15477 compared to 14915 for the EPYC 74F3.

Who should pick the EPYC 7543? Any deployment where the measured Cinebench workloads are representative of the intended use. The 32-core, 64-thread configuration delivers higher scores in both single-core and multi-core rendering tests. The EPYC 7543 also has a larger die footprint at 8x 81 mm² compared to 4x 81 mm² for the EPYC 74F3, which reflects its higher core count.

Who should pick the EPYC 74F3? The case is narrower but not empty. The EPYC 74F3 has a higher boost clock at 4.00 GHz versus 3.70 GHz, which may benefit workloads that are sensitive to maximum clock speed and are not captured by the Cinebench suite. It also carries a lower launch MSRP of $2900, compared to $3761 for the EPYC 7543. Both chips share the same 7 nm process node from TSMC, the same Zen 3 architecture, the same Milan codename, and the same 256 MB shared L3 cache.

The percentile ranking is identical at 69 for both, and both use the AMD Socket SP3 platform with eight-channel DDR4 memory support and 204.8 GB/s memory bandwidth. The TDP differs, with the EPYC 7543 rated at 225 watts and the EPYC 74F3 at 240 watts, meaning the higher-clocked part draws more power despite having fewer cores.

For buyers prioritizing raw benchmark performance in the tested workloads, the EPYC 7543 is the clear choice. For buyers who value the higher boost clock and lower launch MSRP of the EPYC 74F3, that processor remains a viable alternative, but the measured data does not show it winning any of the recorded tests.

Head-to-Head Benchmarks

The head-to-head results are remarkably consistent. Every test in the comparison shows the EPYC 7543 winning by 3.8%. This uniformity suggests that the performance difference between these two processors is structural rather than workload-specific.

In Cinebench R15 multicore, the EPYC 7543 scores 5393 against 5197 for the EPYC 74F3. That is a 196-point gap. The R15 single-core test shows 761 versus 733, a 28-point gap. Both represent the same 3.8% delta.

Cinebench R20 multicore follows the pattern: 22473 for the EPYC 7543, 21657 for the EPYC 74F3. The single-core R20 result is 3172 versus 3057. Again, 3.8%.

Cinebench R23 multicore delivers the largest absolute gap in the dataset: 53509 versus 51566, a difference of 1943 points. The R23 single-core test shows 7554 versus 7279, a 275-point gap. The percentage difference remains 3.8%.

The biggest wins for the EPYC 7543, in absolute score terms, are in the multicore tests, where the 32-core part has more threads to deploy. The biggest wins for the EPYC 74F3, relatively speaking, do not exist in this dataset; it does not win any recorded benchmark. The closest the EPYC 74F3 comes is maintaining the same 3.8% deficit in every test, which indicates that its higher 4.00 GHz boost clock is not enough to overcome the EPYC 7543's combination of similar base clock and additional cores.

The average benchmark scores reinforce the head-to-head results. The EPYC 7543 averages 15477, while the EPYC 74F3 averages 14915, a difference of 562 points. Both chips rank at the 69th percentile, and their nearest rivals in the database are similar in average score. The EPYC 7543's nearest rival, the Intel Core 5 211TE, is within 0.7%, while the EPYC 74F3's nearest rival, the Intel Core i7-9750H, is within 0.2%.
