AMD EPYC 8434P vs Intel Xeon 6730P Comparison

The AMD EPYC 8434P and Intel Xeon 6730P are two contemporary server processors with distinctly different design philosophies, as reflected in the recorded benchmark data. The AMD part, with 48 cores and 96 threads, faces the Intel part, which has 32 cores and 64 threads. The data shows a clear split: the Intel Xeon 6730P wins a majority of the benchmark tests, 13 out of 17, while the AMD EPYC 8434P secures 4 decisive victories in specific workload categories. This analysis examines the recorded performance metrics to determine where each processor excels and which workloads favor one architecture over the other.

Where Each One Wins

The Intel Xeon 6730P demonstrates dominance across the Cinebench rendering suite and several PassMark sub-tests. In all six Cinebench tests, the Intel processor holds a consistent 10.3% advantage over the AMD EPYC 8434P. This includes both multi-core and single-core workloads, with scores like 62,996 versus 56,516 in Cinebench R23 multi-core and 8,893 versus 7,978 in single-core. The consistency of this delta across all Cinebench versions indicates a fundamental performance edge in this rendering workload, likely stemming from the Intel part's higher boost clock of 3.80 GHz compared to the AMD's 3.10 GHz.

The Intel processor also wins in several PassMark categories that reward raw single-thread speed and specific instruction execution. The passmark_single_thread score of 2,995 versus 2,448 represents an 18.3% advantage. More dramatically, the passmark_find_prime_numbers test shows Intel at 686 versus AMD's 298, a massive 56.6% lead. The passmark_physics test also heavily favors Intel, with a score of 8,606 versus 4,036, a 53.1% difference. In floating point math, Intel leads by 4.9%, scoring 226,838 against 215,669. The passmark_extended_instructions test shows a 10.4% Intel advantage, with scores of 96,204 versus 86,189.

The AMD EPYC 8434P wins in four specific PassMark categories that highlight its core count advantage. The most significant win is in data encryption, where AMD scores 97,254 versus Intel's 55,964, a massive 73.8% lead. Integer math also heavily favors AMD, with a score of 385,290 against 290,740, a 32.5% advantage. In data compression, AMD leads with 1,412,835 versus 1,138,470, a 24.1% difference. Finally, random string sorting shows AMD ahead by 10.5%, scoring 125,932 versus 113,919. These wins demonstrate that the AMD part's higher core count and thread count translate into clear advantages in parallel integer-heavy and data-processing tasks.

The Verdict

The benchmark data presents a clear choice based on workload type. The Intel Xeon 6730P is the better option for users prioritizing single-threaded performance, rendering workloads, and physics simulations. Its consistent 10.3% lead across all Cinebench tests, combined with the 53.1% advantage in physics and 18.3% lead in single-thread tests, makes it the superior choice for applications that rely on high clock speeds and per-core efficiency. The processor's 3.80 GHz boost clock, compared to AMD's 3.10 GHz, appears to drive these wins.

The AMD EPYC 8434P is the better choice for workloads that scale with core count and involve heavy integer mathematics, encryption, or data compression. The 73.8% lead in data encryption and 32.5% lead in integer math are substantial margins that would translate to significant real-world performance differences in database operations, cryptographic tasks, and scientific computing. The 48-core configuration provides the parallel throughput necessary for these tasks, even if individual cores are slower than Intel's.

For users running a mix of workloads, the data suggests the Intel Xeon 6730P provides more balanced performance, winning 13 of 17 tests. However, the AMD processor's wins are often by larger margins, particularly in data encryption. The average benchmark score places AMD at 146,881 versus 124,756 for Intel, with AMD ranking in the 98th percentile of all CPUs compared to Intel's 97th percentile. This indicates that, on average, the AMD part scores higher across all recorded benchmarks, despite losing the majority of individual tests, because its wins are so substantial.

Head-to-Head Benchmarks

The largest win for the Intel Xeon 6730P comes in the passmark_find_prime_numbers test, where it scores 686 against AMD's 298, a 56.6% advantage. This test typically rewards high clock speeds and efficient integer operations per core. Similarly, the passmark_physics test shows Intel ahead by 53.1%, with scores of 8,606 versus 4,036. These two tests represent the most extreme performance gaps between the processors.

The largest win for the AMD EPYC 8434P is in data encryption, with a 73.8% lead (97,254 versus 55,964). This is the single biggest margin in either direction across all benchmarks. The AMD part also shows a 32.5% advantage in integer math (385,290 versus 290,740) and a 24.1% lead in data compression (1,412,835 versus 1,138,470).

The Cinebench results are remarkably consistent, with all six tests showing exactly a 10.3% delta in Intel's favor. This includes the multi-core tests where one might expect the 48-core AMD part to close the gap, but the Intel Xeon 6730P still manages to score 62,996 versus 56,516 in Cinebench R23 multi-core. The single-thread Cinebench tests show similar margins, with Intel leading 8,893 versus 7,978 in R23 single-core.

The passmark_multithread test shows Intel ahead by 10.3%, scoring 74,113 versus 66,490, despite AMD having 48 cores versus Intel's 32. In contrast, the passmark_single_thread test shows a larger 18.3% Intel advantage, with scores of 2,995 versus 2,448. The floating point math test shows a narrow 4.9% Intel lead (226,838 versus 215,669), while extended instructions show a 10.4% Intel advantage (96,204 versus 86,189).
