AMD EPYC 7543 vs Intel Core Ultra 5 134U Comparison

Head-to-Head Benchmarks

The benchmark data for these two processors is decisively one-sided. Across all six recorded Cinebench comparisons, the AMD EPYC 7543 takes every single win, and the margins are substantial. The closest contest is in Cinebench R15 single-core, where the EPYC 7543 leads by 71%. The widest gap appears in Cinebench R23 multi-core, where the EPYC 7543 is 89.6% ahead. There is no benchmark category in the database where the Intel Core Ultra 5 134U records a win.

Starting with multi-core performance, the pattern is consistent and severe. In Cinebench R15 multi-core, the EPYC 7543 scores 5393 against the Ultra 5 134U's 894, a delta of -83.4% for the Intel part. The Cinebench R20 multi-core run shows 22473 versus 4725, a 79% deficit. Cinebench R23 multi-core is the most extreme result: the EPYC 7543 posts 53509 while the Ultra 5 134U manages 5572, leaving the Intel chip 89.6% behind. These are not marginal differences that could be explained by cooling or silicon lottery variance; a 32-core Zen 3 server part and a 12-core Meteor Lake mobile part are simply operating in different performance tiers for heavily threaded workloads.

Single-core results tell the same story. Cinebench R15 single-core sees the EPYC 7543 at 761 against 221 on the Intel side, a 71% gap. Cinebench R20 single-core is 3172 against 666, a 79% deficit, and Cinebench R23 single-core is 7554 against 1576, another 79.1% shortfall. Notably, the EPYC 7543's single-core wins are driven by a 3.70 GHz boost clock, which is well below the Ultra 5 134U's 4.40 GHz boost clock, yet the EPYC still wins outright in single-threaded tests. The Zen 3 architecture's core design efficiency outweighs the raw clock speed disadvantage in the recorded data.

Looking at the average benchmark scores places both chips in the same general neighborhood of the overall CPU landscape. The Ultra 5 134U averages 15910, sitting at the 70th percentile of all CPUs, with nearest rivals including the AMD Ryzen 5 40 at 15882 (0.2% behind) and the AMD EPYC 9334 at 15940 (0.2% ahead of the Intel part). The EPYC 7543 averages 15477 at the 69th percentile, with nearest rivals like the Intel Core 5 211TE at 15370 (0.7% behind) and the AMD EPYC 9254 at 15756 (1.8% behind). This means that despite the huge Cinebench deltas, the aggregate benchmark data shows both products sit within a narrow band near the 69th to 70th percentile range in the database's full CPU ranking.

What matters for interpretation is that the EPYC 7543's advantages are not spread across both single-threaded tests consistently, while the PassMark data for the Ultra 5 134U, while showing strong multi-threaded numbers in its own right (PassMark multi-thread score of 12464), in the context of the head-to-head data the EPYC 7543 dominates every single comparison. The Intel part's PassMark single-thread score of 3063 tells you it can handle lighter workloads fine, but the EPYC 7543's Cinebench numbers show a part that leaves nothing on the table in any workload category. There are no wins to walk through "each way" for the Intel part in this matchup; the database records zero wins for the Ultra 5 134U and every win for the EPYC 7543.

In the passmark tests where the Ultra 5 134U has recorded data points such as integer math at 51306 and floating point math at 32425, the EPYC 7543 has no recorded PassMark scores in the database for comparison, so you cannot make a direct comparison on those tests, and the head-to-head data only lists the six Cinebench tests. That lack of overlap means the only measured comparisons you can cite with exact head-to-head numbers are all EPYC wins.

The data says it clearly: if you are comparing these two based on measured scores, the AMD EPYC 7543 wins every benchmark where the two share in common, by margins ranging from 71% to 89.6%.

The Verdict

Pick the AMD EPYC 7543 for any workload where you need more compute throughput, and the data overwhelmingly supports that choice. Its 32 cores and 64 threads give it a 2.67x core count advantage over the Ultra 5 134U, and that physical headroom shows in the numbers with an 89.6% lead in Cinebench R23 multi-core and a 83.4% lead in Cinebench R15 multi-core, so for rendering, rendering, compilation, server-side processing, the EPYC 7543 is the only rational choice. Its 225 watt TDP tells you it is built for sustained load, and its 256 MB shared L3 cache, eight-channel DDR4 memory support, 204.8 GB/s memory bandwidth, ECC memory, and 128 PCIe Gen 4 lanes (CPU only) position it for serious server duty.

Where Each One Wins

The AMD EPYC 7543 wins every head-to-head benchmark category recorded: Cinebench R15 multi-core, R15 single-core, R20 multi-core, R20 single-core, R23 multi-core, and R23 single-core. Its largest wins are in heavily threaded workloads, with an 89.6% lead in Cinebench R23 multi-core and a 83.4% lead in R15 multi-core. It also wins single-threaded tests by 71% to 79.1%, meaning it offers no compromise for lightly threaded tasks either. Its 32 cores, 64 threads, 256 MB L3 cache, and 204.8 GB/s memory bandwidth make it the clear choice for server, workstation, and content-creation workloads where multi-threaded throughput dominates.

The Intel Core Ultra 5 134U wins no recorded benchmark in this matchup. However, the data shows its strengths lie outside the comparison tests: it has integrated Arc Xe-LPG 64EU graphics, a 9 watt TDP, and a 4.40 GHz boost clock. It is the only one of the two with an integrated GPU, making it usable in compact mobile systems without a discrete graphics card. Its 12 MB shared L3 cache and 12 cores provide adequate performance for mobile productivity, and its DDR5 memory support with a dual-channel bus aligns with the mobile market segment. For any use case that involves a laptop or a low-power embedded system with integrated graphics, the Ultra 5 134U is the relevant part, but in raw compute benchmarks, the EPYC 7543 stands alone as the winner in every measured category.
