AMD EPYC 4545P vs Intel Xeon 6724P Comparison

Where Each One Wins

The recorded benchmark data splits these two server processors into distinct use-case territories. The AMD EPYC 4545P wins 13 of the 17 head-to-head tests, while the Intel Xeon 6724P takes 4. That raw count, however, hides the nature of each victory.

The AMD part dominates in rendering workloads. In Cinebench R15, R20, and R23, both multi-core and single-core, the EPYC 4545P wins every test by a uniform 7.9%. That consistency suggests a per-clock advantage rather than a core-count edge, since both chips have 16 cores and 32 threads. The AMD processor also leads in integer math by 24%, in data encryption by 9.5%, in random string sorting by 7.8%, and in multithreaded PassMark by 4.2%. Data compression is nearly a tie, with the AMD part ahead by 1.4%.

The Intel Xeon 6724P wins in four specific areas: physics simulation, prime number finding, extended instructions, and floating-point math. The physics win is substantial at 34.9%, and prime number finding shows a 21.5% lead. Extended instructions come in 14.5% ahead, while floating-point math is 6.6% better on the Intel side.

The pattern is clear. The AMD EPYC 4545P handles general computation, rendering, encryption, and integer-heavy tasks better. The Intel Xeon 6724P pulls ahead in physics solvers and specialized instruction workloads. For a database or web server, the AMD chip's integer and encryption advantages matter more. For scientific simulation or floating-point-heavy analysis, the Intel part has the edge.

Architecture Differences

The two processors come from different design philosophies. The AMD EPYC 4545P uses Zen 5 architecture on a 4 nm TSMC process, with a die size of 2x 70.6 mm² and 16,630 million transistors. It belongs to the EPYC 4005 series, codenamed Grado. The Intel Xeon 6724P uses Granite Rapids architecture on Intel's 5 nm process, part of the Xeon 6 family (Granite Rapids-SP).

Cache layouts differ notably. The AMD part provides 80 KB of L1 per core and 1 MB of L2 per core, with 64 MB of L3 cache. The Intel part has larger per-core caches: 112 KB L1 and 2 MB L2, plus 72 MB of shared L3. This larger cache per core may explain some of the Intel wins in physics and floating-point work, where working sets benefit from more on-die storage.

Memory architecture diverges sharply. The AMD EPYC 4545P supports dual-channel DDR5 with 89.6 GB/s of memory bandwidth. The Intel Xeon 6724P supports eight-channel DDR5 with 409.6 GB/s, which is roughly 4.6 times the bandwidth. This difference should matter for memory-bound workloads, yet the benchmark data shows the AMD chip winning most tests anyway. The Intel part's bandwidth advantage may only surface in specific access patterns not captured by these benchmarks.

PCIe connectivity also differs. The AMD chip offers 24 PCIe Gen 5 lanes, while the Intel part offers 88 lanes. For systems needing many expansion cards, NVMe drives, or GPUs, the Intel part provides far more headroom. The AMD chip includes integrated Radeon Graphics, while the Intel Xeon has no integrated graphics.

Socket compatibility separates them completely. The AMD EPYC 4545P uses AMD Socket AM5, the same socket as consumer Ryzen parts. The Intel Xeon 6724P uses Intel Socket 4710, a server-specific platform. This means platform costs and upgrade paths differ substantially, though pricing is not covered in this analysis.

Head-to-Head Benchmarks

The Cinebench results tell a consistent story. Across R15, R20, and R23, the AMD EPYC 4545P wins every test by exactly 7.9%. The multi-core scores are 4745 versus 4399 in R15, 19773 versus 18330 in R20, and 47079 versus 43643 in R23. Single-core results follow the same pattern: 669 versus 620 in R15, 2791 versus 2587 in R20, and 6646 versus 6161 in R23. The uniformity of this delta suggests the AMD architecture simply executes this workload more efficiently per clock.

PassMark integer math shows the largest AMD win at 24%, with scores of 213485 versus 172216. Data encryption is another strong AMD area, winning 37598 to 34332, a 9.5% margin. Random string sorting goes to AMD by 7.8% (73850 versus 68477). The multithreaded PassMark score favors AMD by 4.2% (53504 versus 51345). Data compression is nearly identical, with AMD ahead by just 1.4% (636279 versus 627185).

The Intel Xeon 6724P claims its biggest win in PassMark physics, scoring 5004 against 3260, a 34.9% advantage. This is the largest delta in either direction across all tests. Prime number finding goes to Intel by 21.5% (372 versus 292). Extended instructions favor Intel by 14.5% (54101 versus 46231). Floating-point math goes to Intel by 6.6% (135404 versus 126505).

The single-thread PassMark test shows a remarkable 31.7% AMD lead: 4318 versus 3279. This is the second-largest delta in the entire comparison, and it aligns with the boost clock difference of 5.40 GHz versus 4.30 GHz. The Intel part's higher base clock (3.60 GHz versus 3.00 GHz) does not compensate in single-threaded workloads.

The Verdict

The data points to a clear overall winner for general server workloads. The AMD EPYC 4545P wins 13 of 17 tests, including all Cinebench rendering tests, integer math, encryption, multithreaded performance, and single-threaded performance. It also has a dramatically lower TDP (65 watts versus 210 watts) and a much lower launch MSRP ($549 versus $3622). For most database, web serving, virtualization, and general compute tasks, the benchmark results favor the AMD chip.

The Intel Xeon 6724P should be chosen for specific workloads where its wins matter. Physics simulation, floating-point math, prime number finding, and extended instruction sets are its territory. The 34.9% physics win is substantial, and the 21.5% prime number advantage shows strength in certain integer algorithms. Additionally, the Intel part offers 88 PCIe Gen 5 lanes versus 24, and 409.6 GB/s of memory bandwidth versus 89.6 GB/s, which may be decisive for systems with heavy I/O or memory access demands not captured in these benchmarks.

The average benchmark scores reflect this split: the AMD part averages 75373 (95th percentile) versus 72396 (94th percentile) for Intel. The AMD chip's nearest rivals include the Intel Core Ultra 9 285 at 75488 (0.2% ahead) and the AMD EPYC 8224P at 75582 (0.3% ahead). The Intel Xeon 6724P sits closest to the Intel Xeon 6517P at 72350 (0.1% behind) and the Intel Core Ultra 7 265KF at 71910 (0.7% behind).

For pure compute density, rendering, and single-thread responsiveness, the AMD EPYC 4545P is the stronger choice according to the recorded data. For physics solvers, floating-point analysis, and systems requiring massive PCIe expansion, the Intel Xeon 6724P justifies its position despite the higher TDP and launch MSRP. The benchmark database shows a split decision, but with the AMD part winning the majority of tested workloads.
