AMD EPYC 7F72 vs Intel Xeon w5-3535X Comparison

The AMD EPYC 7F72 and Intel Xeon w5-3535X represent two distinct approaches to high-core-count workstation processing, with benchmark data showing a clear split between traditional compute workloads and specialized tasks. The Intel part wins 12 of 17 head-to-head comparisons, but the AMD part claims decisive victories in several areas, making the choice highly workload-dependent. Both processors sit at the 96th percentile among all CPUs, though their average benchmark scores differ by roughly 4.7%, with the EPYC 7F72 averaging 85,072 against the Xeon's 81,115.

Head-to-Head Benchmarks

The most striking pattern in the data is the sheer magnitude of AMD's wins versus the narrowness of Intel's. In Cinebench tests, the Xeon w5-3535X consistently edges out the EPYC 7F72 by a tight 2.5% margin across R15, R20, and R23, in both single-core and multi-core variants. For instance, Cinebench R23 multi-core shows the Intel part scoring 45,974 against AMD's 44,829, while single-core R23 shows 6,490 versus 6,328. These are consistent but small advantages, suggesting the Intel architecture holds a modest lead in general-purpose rendering workloads.

Conversely, AMD's wins are often lopsided. The most extreme case is PassMark data encryption, where the EPYC 7F72 scores 56,261 against the Xeon's 36,784 — a 52.9% advantage. Similarly, PassMark find prime numbers shows AMD leading 498 to 269, an 85.1% delta. PassMark physics also favors AMD heavily at 6,459 versus 3,547, a 82.1% gap. These results indicate the Zen 2 architecture's strengths in specific computational patterns, particularly those involving cryptographic operations and integer-heavy algorithmic work.

The data compression test falls in AMD's favor with a 10.6% lead (808,795 versus 731,388), and random string sorting shows a 39.1% advantage (102,436 versus 73,618). These workloads often benefit from large caches, and AMD's 192 MB shared L3 cache versus Intel's 52.5 MB likely explains the pattern.

Intel's wins extend beyond Cinebench into several PassMark subtests. Floating point math shows the Xeon ahead by 25.7% (145,924 versus 108,437), and extended instructions favor Intel by 22% (60,183 versus 46,936). Integer math is closer, with Intel leading 186,158 to 181,103, a 2.7% edge. The single-threaded PassMark score reveals the largest Intel advantage: 3,602 versus 2,384, a 33.8% delta. This single-thread gap is consistent with the boost clock difference — Intel boosts to 4.80 GHz versus AMD's 3.70 GHz — though the base clocks are closer at 2.90 GHz and 3.20 GHz respectively.

FAQ

Q: Where does the AMD EPYC 7F72 have its biggest advantage?

A: The largest delta is in PassMark find prime numbers, where AMD scores 498 against Intel's 269, an 85.1% lead. Data encryption also shows a massive 52.9% advantage, with AMD scoring 56,261 versus 36,784.

Q: How do the processors compare in single-threaded performance?

A: Intel dominates single-threaded workloads. PassMark single-thread shows 3,602 versus 2,384, a 33.8% difference. Cinebench R23 single-core shows a smaller gap: 6,490 versus 6,328, still favoring Intel by 2.5%.

Q: Which processor has better memory bandwidth potential?

A: The Intel Xeon w5-3535X supports eight-channel DDR5 with a theoretical bandwidth of 307.2 GB/s, while the AMD EPYC 7F72 uses eight-channel DDR4 with 204.8 GB/s. This represents a 50% higher bandwidth figure for Intel.

Q: What do the overall average benchmark scores indicate?

A: The AMD EPYC 7F72 has a higher average benchmark score of 85,072 compared to the Intel Xeon's 81,115, despite Intel winning more individual tests. This reflects the magnitude of AMD's wins in specific workloads.

Q: Are these processors comparable in overall performance tier?

A: Both rank at the 96th percentile among all CPUs. The AMD part's nearest rival is the Intel Core Ultra 9 290K Plus at 84,003 (1.3% behind), while the Intel Xeon's closest competitor is the Intel Core i9-14900KS at 81,127 (0% delta).

Architecture Differences

The fundamental architectural split is process node and core design. The AMD EPYC 7F72 uses TSMC's 7 nm process with a 74 mm² die size and 3,800 million transistors, built on the Zen 2 architecture. The Intel Xeon w5-3535X uses Intel's 10 nm process with a larger 4x 477 mm² die configuration (totaling roughly 1,908 mm² across four dies) on the Sapphire Rapids platform.

Core counts differ meaningfully: AMD offers 24 cores and 48 threads, while Intel provides 20 cores and 40 threads. This gives AMD a 20% core advantage, yet Intel still wins most multi-threaded tests, suggesting higher per-core efficiency. Cache organization diverges sharply: AMD allocates 96 KB L1 and 512 KB L2 per core, with a massive 192 MB shared L3. Intel uses 80 KB L1 and 2 MB L2 per core, with a much smaller 52.5 MB L3. The larger per-core L2 on Intel (2 MB versus 512 KB) likely helps single-thread performance.

Memory architecture also differs fundamentally. AMD pairs with DDR4 across an eight-channel bus, while Intel uses DDR5 across the same eight-channel width, yielding 307.2 GB/s versus 204.8 GB/s. PCIe generation differs too: AMD provides Gen 4, while Intel offers Gen 5 with 112 lanes (CPU only). The Intel part includes an unlocked multiplier, whereas the AMD part is locked. Intel's socket is Socket 4677, and AMD uses Socket SP3. The release dates are far apart: the EPYC launched in April 2020, while the Xeon arrived in August 2024.

The Verdict

The data supports a clear differentiation based on workload type. For general rendering and multi-threaded productivity, the Intel Xeon w5-3535X is the safer choice — it wins every Cinebench test by 2.5% and PassMark multithread by 2.5%, despite having fewer cores. Its single-thread advantage is decisive at 33.8% in PassMark, which will translate to snappier interactive performance in many workstation applications.

However, for specialized compute tasks involving encryption, prime number generation, data compression, or random string sorting, the AMD EPYC 7F72 offers advantages ranging from 10.6% to 85.1%. The physics test also heavily favors AMD at 82.1%. Users running these specific workloads would see substantial throughput gains from the EPYC part.

The Xeon's 300 W TDP versus AMD's 240 W indicates higher power draw for the Intel part, which may matter in dense deployments. The Intel part's DDR5 support and Gen 5 PCIe provide modern I/O headroom, while AMD's larger L3 cache appears to drive its wins in memory-latency-sensitive tasks. The Intel part's unlocked multiplier offers overclocking potential that the locked AMD part lacks.

Ultimately, the benchmark data suggests: pick the Intel Xeon w5-3535X for balanced, single-thread-sensitive, and floating-point-heavy workloads; pick the AMD EPYC 7F72 for cryptographic, compression, and physics-based compute tasks where its wins are often multiples of Intel's advantages. The 96th percentile ranking for both confirms they are top-tier parts, but their strengths rarely overlap.
