CPU Comparison

The benchmark data presents a stark contrast between two server processors: the AMD EPYC 74F3 and the Intel Xeon 6315P. While both occupy the same 69th percentile in the global CPU database, their performance profiles are fundamentally different, with the AMD part delivering massive multi-threaded throughput and the Intel part offering a low-power, entry-level alternative. This analysis breaks down the head-to-head results, architectural divergence, and practical implications based solely on the provided data.

Head-to-Head Benchmarks

The Cinebench results are unambiguous, with the AMD EPYC 74F3 winning all six head-to-head comparisons by a landslide. The margin of victory is remarkably consistent across every test, hovering near 409%. In the Cinebench R15 multicore test, the EPYC 74F3 scores 5197 against the Xeon 6315P’s 1021, a 409% advantage. The single-core R15 test shows the same 409% delta, with scores of 733 and 144 respectively. This pattern repeats in R20, where the multicore scores are 21657 versus 4256 (408.9% delta) and single-core scores are 3057 versus 600 (409.5% delta). The R23 results continue the trend: 51566 versus 10134 for multicore (408.8% delta) and 7279 versus 1430 for single-core (409% delta).

These numbers indicate that the EPYC 74F3 is not just faster in parallel workloads; it also dominates in lightly-threaded tasks. The consistent ~409% delta across both single and multi-core tests suggests a fundamental per-clock performance advantage, not merely a core-count scaling effect. The Xeon 6315P’s higher boost clock of 4.70 GHz compared to 4.00 GHz does nothing to close the gap, as the EPYC’s superior architecture and larger cache deliver higher instructions-per-clock.

The Intel Xeon 6315P does have additional PassMark benchmark results in its profile, but no comparable PassMark data exists for the AMD part in the head-to-head table. Therefore, the only direct comparisons available are the six Cinebench tests, and the AMD EPYC 74F3 wins all of them. The data shows zero wins for the Intel processor in any head-to-head benchmark.

Where Each One Wins

Based on the benchmark wins, the AMD EPYC 74F3 is the clear victor in every measurable category. It wins all six Cinebench tests, which covers both single-threaded and multi-threaded rendering workloads. The 24-core, 48-thread configuration provides massive parallelism, evidenced by the R23 multicore score of 51566. This makes the EPYC 74F3 suitable for heavy server workloads, virtualization, and content creation tasks that scale across many threads.

The Intel Xeon 6315P wins no benchmarks in this comparison. However, its profile includes a low 55W TDP compared to the AMD part’s 240W, suggesting a use case focused on power efficiency rather than raw performance. The Xeon 6315P has additional PassMark scores in its own profile, such as 118313 in data compression and 33496 in floating point math, but without corresponding scores for the EPYC 74F3, no direct comparison can be made. The data indicates that the Xeon 6315P is positioned for scenarios where minimal power draw is paramount, at the cost of significant performance. Its 4 cores and 4 threads limit its parallel capabilities, making it more of a low-end server entry point.

For users prioritizing performance, the EPYC 74F3 is the only choice based on the benchmark data. For those requiring a minimal-footprint, low-power server processor, the Xeon 6315P offers a functional albeit much slower alternative. The AMD part’s 256 MB shared L3 cache and eight-channel memory bus also point to a design intended for data-intensive workloads, whereas the Xeon’s 12 MB L3 and dual-channel bus are far more modest.

Architecture Differences

The two processors are built on fundamentally different architectures and process nodes. The AMD EPYC 74F3 uses the Zen 3 architecture, codenamed Milan, fabricated on a 7 nm process by TSMC. It has 24 cores and 48 threads. The Intel Xeon 6315P uses the Raptor Lake architecture, specifically Raptor Lake-R, on Intel’s 10 nm process. It has just 4 cores and 4 threads, meaning no hyper-threading support.

Cache configurations differ substantially. The EPYC 74F3 features 64 KB of L1 cache per core, 512 KB of L2 cache per core, and a massive 256 MB of shared L3 cache. The Xeon 6315P has 80 KB of L1 per core, 1.25 MB of L2 per core, and only 12 MB of shared L3. The EPYC’s large L3 cache is a defining feature for server workloads, helping to keep data local and reduce memory latency.

Memory support also diverges. The EPYC 74F3 supports DDR4 only, across an eight-channel memory bus with a bandwidth of 204.8 GB/s. The Xeon 6315P supports both DDR4 and DDR5, but only on a dual-channel bus, with no bandwidth figure provided in the data. The EPYC’s memory bandwidth is a critical advantage for many-core operations. PCIe support differs as well: the EPYC offers Gen 4 with 128 lanes (CPU only), while the Xeon offers Gen 5 with 16 lanes (CPU only). The EPYC’s massive lane count enables extensive I/O expansion, whereas the Xeon is limited to a single add-in card or a few NVMe drives.

Physical specifications show the EPYC 74F3 uses AMD Socket SP3 and has a die size of 4x 81 mm², with 33,200 million transistors. The Xeon 6315P uses Intel Socket 1700 and has a die size of 163 mm², with no transistor count listed. The EPYC is a multi-chip module design, while the Xeon appears to be a monolithic die. The Xeon has integrated graphics listed as "N/A," while the EPYC has no integrated graphics field populated. Both support ECC memory and have locked multipliers.
