AMD EPYC 7473X vs Intel Xeon 6315P Comparison

The data presents an unusual head-to-head: the AMD EPYC 7473X and Intel Xeon 6315P are polar opposites in design philosophy, yet they land on identical average benchmark scores of 14574. This is a case where the aggregate number hides a complete divergence in workload suitability. The EPYC 7473X is a 24-core, 48-thread server monster, while the Xeon 6315P is a 4-core, 4-thread low-power part. Consequently, the benchmark results show a clean sweep for AMD in the tested Cinebench workloads, but the architectural gulf between them dictates that each processor serves a completely different purpose.

Where Each One Wins

The AMD EPYC 7473X wins decisively in every single multithreaded and single-threaded Cinebench test recorded. Its smallest margin of victory is 397.2% in Cinebench R20 multi-core, and its largest is 397.8% in Cinebench R20 single-core. This is not a marginal lead; it is a categorical outperformance in CPU rendering and compute tasks. The data shows the EPYC 7473X is the clear choice for any workload that scales with core count, such as 3D rendering, video encoding, or scientific simulation, where its 24 cores and 48 threads can be fully utilized.

The Intel Xeon 6315P, despite its 0 wins in the head-to-head table, has its own domain of dominance that is implied by the specification differences. Its 55W TDP, compared to the EPYC's 240W, makes it the winner in power-constrained environments. The Xeon 6315P also supports both DDR4 and DDR5 memory, offering flexibility in system design. Its dual-channel memory bus and 16 PCIe Gen 5 lanes point to a more streamlined, single-socket solution for lighter server tasks, edge computing, or as a highly efficient entry point. The data does not include power or price benchmarks, but the specification sheet clearly defines its winning arena: efficiency and simplicity, not raw compute throughput.

Architecture Differences

The two processors are built on fundamentally different architectures from different eras. The AMD EPYC 7473X is based on the Zen 3 architecture, specifically the Milan-X codename, and is manufactured on a 7 nm process by TSMC. It utilizes a massive 768 MB of shared L3 cache, a defining feature of the Milan-X line, spread across eight chiplets, each with a die size of 81 mm². In contrast, the Intel Xeon 6315P is based on the Raptor Lake architecture (Raptor Lake-R codename) on a 10 nm process from Intel, with a single, larger 163 mm² die.

The core configurations are starkly different. The AMD part has 24 cores and 48 threads, with a base clock of 2.80 GHz and a boost clock of 3.70 GHz. The Intel part has only 4 cores and 4 threads, with the same 2.80 GHz base clock but a much higher 4.70 GHz boost clock. This explains the scores: the Intel's high boost clock cannot compensate for its lack of cores and threads in multithreaded tests. Cache hierarchies also differ significantly. The EPYC has 64 KB of L1 and 512 KB of L2 per core, while the Xeon has 80 KB of L1 and a larger 1.25 MB of L2 per core, but only 12 MB of shared L3 cache versus the EPYC's 768 MB. Memory support is also a differentiator: the EPYC uses eight-channel DDR4 with a bandwidth of 204.8 GB/s, whereas the Xeon uses dual-channel DDR4 or DDR5.

Head-to-Head Benchmarks

The benchmark results are unambiguous. In Cinebench R23 multi-core, the AMD EPYC 7473X scores 50388, while the Intel Xeon 6315P scores 10134. This is a 397.2% advantage for AMD, translating to nearly 5 times the performance. This is the most extreme gap in the test suite. The story is similar in Cinebench R20 multi-core, where the EPYC scores 21162 against the Xeon's 4256, again a 397.2% difference. Even in single-core tests, where the Xeon's higher 4.70 GHz boost clock should help, the EPYC wins by a similar margin. In Cinebench R23 single-core, the EPYC scores 7113 versus the Xeon's 1430, a 397.4% lead. The same pattern holds in Cinebench R15, with the EPYC leading by 397.4% in multi-core and 397.2% in single-core. The data shows that the EPYC's advantage is consistent and overwhelming across all rendering workloads, suggesting that its massive L3 cache and superior IPC provide a benefit that the Xeon's higher clock speed cannot overcome.

The Verdict

The verdict is dictated by workload, not by average score. For any application that demands high compute throughput, the AMD EPYC 7473X is the only choice. The data shows it is approximately 397% faster in Cinebench R23 multi-core, a performance gap that is insurmountable for the Intel part. A user running heavy multithreaded applications should select the EPYC 7473X without hesitation. Its 24-core, 48-thread configuration and 768 MB of L3 cache provide the resources necessary for demanding server and workstation tasks.

The Intel Xeon 6315P is not a competitor in this space; it is a different tool. Its 4-core, 4-thread design and 55W TDP make it suitable for scenarios where power consumption is the primary constraint. The data shows it is dramatically slower in rendering, but its specification sheet indicates it is a low-power, entry-level server processor. A user building a low-power server or a workstation that does not require heavy CPU rendering would select the Xeon 6315P for its efficiency and its support for modern DDR5 memory. It is the correct choice for a specific, power-sensitive niche, while the EPYC is the correct choice for raw performance.
