AMD EPYC 72F3 vs Intel Xeon W-2191B Comparison

Head-to-Head Benchmarks

The recorded data paints an unusually consistent picture in this matchup. Across all six Cinebench iterations, the Intel Xeon W-2191B wins every single test, and the margin is remarkably uniform. In Cinebench R15 multi-core, the Intel scores 2407 against the AMD EPYC 72F3's 2334, a delta of 3%. The single-core R15 result is similarly narrow: 339 versus 329, a 2.9% gap. This pattern repeats in R20 multi-core (10032 vs 9728) and R20 single-core (1416 vs 1373), each showing a 3% advantage for Intel. The R23 results continue the trend: 23887 versus 23164 in multi-core and 3372 versus 3270 in single-core, again a 3% delta.

What is striking is that the EPYC 72F3 never closes the gap in any workload category, despite having a substantially higher base clock of 3.70 GHz compared to the Intel's 2.30 GHz. The Intel's boost clock of 4.30 GHz edges out the AMD's 4.10 GHz, which helps explain the single-core results, but the multi-core victory is more nuanced. The Intel packs 18 cores and 36 threads against the AMD's 8 cores and 16 threads, and that core count advantage appears to more than compensate for the AMD's clock speed superiority. The data shows a consistent 3% performance lead for Intel across the board, which suggests the architecture differences translate into a steady, predictable advantage rather than one that fluctuates by workload type.

Looking at the broader database context, both CPUs sit at the 62nd percentile among all tested processors. The AMD EPYC 72F3 has an average benchmark score of 6700, placing it just 0.1% behind the Intel Xeon Gold 5317 (6710) and 0.2% behind the Intel Xeon D-2775TE (6711). It sits 0.6% ahead of the Core i9-9940X and 0.8% ahead of the Ryzen Threadripper 2950X. The Intel Xeon W-2191B, with an average score of 6531, lands exactly level with the Core i9-7960X (6533, delta 0%), 0.3% ahead of the Xeon D-2796TE, and 0.6% and 0.8% behind the Atom x7405C and Core i5-13500E respectively. This places the two contenders within 2.6% of each other on average, even though the head-to-head Cinebench results show a consistent 3% gap favoring Intel.

Architecture Differences

The fundamental design philosophies could hardly be more different. The AMD EPYC 72F3 uses the Zen 3 architecture on a 7 nm process from TSMC, while the Intel Xeon W-2191B relies on the Skylake architecture on Intel's 14 nm process. The process node difference is significant: 7 nm versus 14 nm, which typically implies better transistor density and power efficiency for the smaller node. However, the measured performance does not reflect an efficiency advantage in raw throughput, as Intel wins all benchmarks despite the older node.

The core configuration is where the largest divergence appears. The EPYC 72F3 has 8 cores and 16 threads, while the Xeon W-2191B offers 18 cores and 36 threads. This 10-core and 20-thread difference is substantial and directly explains the multi-core results. The AMD compensates with a 3.70 GHz base clock versus 2.30 GHz, and a 4.10 GHz boost versus 4.30 GHz. The Intel's higher boost clock gives it an edge in lightly threaded scenarios, while the core count advantage dominates heavily threaded workloads.

Cache hierarchies diverge sharply. The AMD provides 64 KB of L1 cache per core, 512 KB of L2 per core, and a massive 256 MB shared L3 cache. The Intel offers the same 64 KB L1 per core but doubles L2 to 1 MB per core, while its shared L3 is only 24.75 MB. The AMD's L3 cache is over ten times larger, which should benefit workloads with large working sets. Yet the benchmark data does not show this translating into a win for AMD, suggesting the software used in these tests either does not stress cache capacity or the Intel's memory subsystem compensates.

Memory support also differs meaningfully. Both support DDR4, but the AMD runs an eight-channel memory bus delivering 204.8 GB/s of bandwidth, while the Intel uses a quad-channel configuration with 85.3 GB/s. The AMD has more than double the memory bandwidth, a substantial theoretical advantage for memory-intensive tasks. Both support ECC memory, which is important for server and workstation reliability.

PCIe capabilities favor AMD heavily: Gen 4 with 128 lanes versus Gen 3 with 48 lanes. This makes the EPYC 72F3 far more capable for systems requiring many high-speed expansion devices or storage controllers. The sockets differ as expected: AMD Socket SP3 for the EPYC, Intel Socket 2066 for the Xeon. The physical die size tells another story: the AMD uses an 8x 81 mm² chiplet design with 33,200 million transistors, while the Intel uses a monolithic 484 mm² die with no transistor count listed in the database.

Where Each One Wins

The Xeon W-2191B wins in every benchmark category recorded, so the division of labor is not about specific test types. Instead, the data implies the Intel wins across the board in these Cinebench workloads. The 3% margin is consistent whether the test is single-core or multi-core, R15, R20, or R23. This uniformity suggests the Intel's advantage is architectural rather than workload-specific.

However, the database also records a Geekbench result for the Intel only: a multi-core score of 9614 and a single-core score of 1182. No Geekbench data exists for the AMD, so direct comparison in that suite is impossible. This absence is notable because it limits the ability to generalize the Cinebench results to other benchmark families.

For single-core scenarios, the Intel's 4.30 GHz boost clock versus 4.10 GHz gives it a small edge, and the 3% delta in single-core tests reflects that. For multi-core scenarios, the 18 cores versus 8 cores is the dominant factor, yet the margin is still only 3%. This indicates the AMD's higher base clock and larger cache are partially closing the core count gap. The AMD's eight-channel memory bandwidth and 256 MB L3 cache could be significant advantages in workloads not represented by Cinebench, such as large database operations or high-performance computing tasks that are memory-bandwidth bound. The Intel's others, the data does not include such tests, so those remain unverified advantages.

The Intel's production status is end-of-life, while the AMD is still active. This suggests availability differs, but the performance relationship remains as measured.

The TDP figures are notable: the AMD draws 180 W while the Intel draws 140 W. Despite the AMD's lower core count, it consumes more power, likely due to its higher base clock and the demands of its large cache and memory controller. The Intel, despite more cores, runs at a lower TDP.

The Verdict

The benchmark data is unambiguous within the tested workloads: the Intel Xeon W-2191B outperforms the AMD EPYC 72F3 in all six Cinebench comparisons, with a consistent 3% margin across single-core and multi-core tests. Anyone prioritizing raw Cinebench throughput should choose the Intel based on these measurements. The Intel's 18 cores and 36 threads provide a structural advantage in multi-threaded rendering, and its 4.30 GHz boost clock edges out the AMD in single-threaded tasks.

However, the AMD EPYC 72F3 offers substantial advantages in other specification areas that the recorded benchmarks do not cover. Its 256 MB L3 cache, eight-channel memory with 204.8 GB/s bandwidth, and PCIe Gen 4 with 128 lanes make it a more capable platform for memory-intensive or I/O-heavy server workloads. The active production status and newer release date (2021 versus 2017) suggest longer-term availability. The AMD also uses a 7 nm process versus 14 nm, which may offer efficiency benefits in certain scenarios.

The launch MSRP of the AMD is $2468, while the Intel has no listed launch MSRP. The production status difference is critical: the AMD is active, the Intel is end-of-life. For new system builds, the AMD is the only one of the two with ongoing availability.

The verdict from the data: if the workload is Cinebench-style rendering and the exact 3% performance edge matters, the Intel Xeon W-2191B wins on measured performance. If the workload involves large datasets, high memory bandwidth demands, or many PCIe devices, the AMD EPYC 72F3 offers specification advantages that the recorded benchmarks do not capture. The choice depends on whether the priority is the measured benchmark wins or the broader platform capabilities.
