AMD EPYC 72F3 vs Intel Xeon Platinum 8260 Comparison

Head-to-Head Benchmarks

The recorded data presents a remarkably consistent picture across all six Cinebench comparisons. The Intel Xeon Platinum 8260 wins every single head-to-head benchmark, with no victories recorded for the AMD EPYC 72F3. The margins are uniform, ranging from 4.3% to 4.4% depending on the workload type. In Cinebench R15 multicore, the Intel part scores 2436 against the EPYC's 2334, a 4.4% advantage. The single-core R15 test shows a similar gap: 343 versus 329, a 4.3% lead for Intel.

Moving to Cinebench R20, the pattern holds precisely. The multicore test records 10152 for Intel against 9728 for AMD, a 4.4% delta. Single-core R20 shows 1433 versus 1373, again a 4.4% margin. The newest workload in the database, Cinebench R23, continues the trend. Intel scores 24173 in multicore against AMD's 23164, a 4.4% difference. In R23 single-core, Intel posts 3412 versus 3270, a 4.3% edge. The consistency of these deltas suggests the performance relationship is stable across rendering generations and does not depend on thread scaling or specific instruction usage.

The average benchmark score in the database reinforces this narrative. The Intel Xeon Platinum 8260 carries an average score of 6992, while the AMD EPYC 72F3 averages 6700. This places the Intel processor in the 63rd percentile of all CPUs in the database, one percentile ahead of the EPYC's 62nd percentile. The nearest rivals for the Intel part include the Intel Core i9-7980XE with an average score of 7018, which is 0.4% above the Xeon, and the Intel Core i9-9960X at 6938, which is 0.8% below. The AMD EPYC 72F3 sits near the Intel Xeon Gold 5317, which scores 6710 with a 0.1% delta, and the Intel Xeon D-2775TE at 6711, a 0.2% delta. Neither processor is an outlier in its peer group; both are solidly mid-pack performers.

Architecture Differences

The two processors come from fundamentally different design philosophies and manufacturing generations. The Intel Xeon Platinum 8260 is built on the Cascade Lake architecture, specifically Cascade Lake-SP, using Intel's 14 nm process node. It integrates 8,000 million transistors. The AMD EPYC 72F3 uses the Zen 3 architecture, codenamed Milan, fabricated by TSMC on a 7 nm process. This node difference is substantial, and the AMD part carries 33,200 million transistors across a die configuration described as 8x 81 mm².

Core counts diverge sharply. The Intel Xeon provides 24 cores and 48 threads, while the AMD EPYC offers 8 cores and 16 threads. This is a 3x difference in core count, yet the benchmark scores are remarkably close. The Intel part's base clock is 2.40 GHz with a boost clock of 3.90 GHz, whereas the AMD part runs at 3.70 GHz base and 4.10 GHz boost. The EPYC's higher clocks partially compensate for its lower core count, but the Intel part still manages to win every test by a small margin.

Cache hierarchies also differ meaningfully. The Intel Xeon has 64 KB of L1 cache per core, 1 MB of L2 per core, and a shared 35.75 MB L3 cache. The AMD EPYC has the same 64 KB L1 per core but a smaller 512 KB L2 per core, compensated by a massive 256 MB shared L3 cache. The L3 difference is substantial, with the EPYC offering over seven times the shared cache capacity. This larger cache likely helps the AMD part close the gap in single-threaded workloads despite its lower core count.

Memory architecture shows further divergence. Both support DDR4 and ECC memory, but the AMD EPYC specifies an eight-channel memory bus with a memory bandwidth of 204.8 GB/s, while the Intel part lists no memory bus width or bandwidth figure in the database. The AMD EPYC also supports PCIe Gen 4 with 128 lanes from the CPU, while the Intel part has no PCIe details recorded. The AMD processor is listed as production status "Active" with a launch MSRP of $2468, while the Intel part has no launch MSRP recorded. The Intel Xeon uses the Intel Socket 3647, and the AMD EPYC uses the AMD Socket SP3.

Release dates show a generational gap. The Intel Xeon Platinum 8260 was released on 2018-12-10, while the AMD EPYC 72F3 arrived on 2021-03-14, more than two years later. The Intel part's generation is listed as "Xeon Platinum (Cascade Lake-SP)", and the AMD part's generation is "EPYC (Zen 3 (Milan))". Neither processor has an unlocked multiplier.

Where Each One Wins

Based strictly on the recorded benchmarks, the Intel Xeon Platinum 8260 wins every workload category. There is no benchmark in the database where the AMD EPYC 72F3 takes the lead. This includes both multicore and single-core tests across three Cinebench versions. The Intel part's advantage in multicore tests, such as Cinebench R15 with a 4.4% delta, likely stems from its 24 cores versus the EPYC's 8 cores. Even with the EPYC's higher clock speeds, the sheer thread count of the Intel part provides a sustained advantage in heavily threaded rendering workloads.

Single-core results are closer but still favor Intel. In Cinebench R23 single-core, the Intel part scores 3412 versus 3270, a 4.3% delta. This is interesting because the AMD EPYC has a higher boost clock, 4.10 GHz versus 3.90 GHz, and a more modern 7 nm process. The Intel architecture apparently extracts more performance per clock in these specific tests, or the EPYC's lower L2 cache per core (512 KB versus 1 MB) limits its single-thread efficiency despite the large L3.

For use cases that benefit from high core counts, such as server virtualization, database workloads, or multi-VM hosting, the Intel Xeon Platinum 8260 appears better positioned. Its 48 threads provide more parallel capacity than the EPYC's 16 threads. For workloads that are sensitive to cache capacity, such as in-memory analytics or large working sets, the AMD EPYC's 256 MB L3 cache could be advantageous, but the recorded Cinebench data does not show this benefit materializing in these specific tests. The AMD part's eight-channel memory bus and 204.8 GB/s bandwidth could favor memory-bound applications, but no memory benchmark data exists in the database to confirm this.

The Verdict

The data is unambiguous: the Intel Xeon Platinum 8260 outperforms the AMD EPYC 72F3 in every recorded benchmark. The margins are small, between 4.3% and 4.4%, but they are consistent across all six tests. The Intel part wins both multicore and single-core workloads, which is notable given the architectural differences. The AMD EPYC 72F3 offers a much larger L3 cache, higher clock speeds, a more advanced process node, and more memory bandwidth, yet it still trails in every Cinebench result.

For a buyer choosing between these two server processors, the Intel Xeon Platinum 8260 delivers higher raw rendering performance in the measured workloads. The AMD EPYC 72F3, however, brings a different set of attributes: 128 PCIe Gen 4 lanes, eight-channel memory, and a 256 MB shared cache. These features do not translate into Cinebench wins, but they may matter for specific server deployments that the database does not cover. The Intel part's 24 cores provide more thread-level parallelism for scale-out workloads, while the EPYC's 8 cores with high clocks and large cache could suit latency-sensitive or lightly threaded tasks.

Given the average benchmark scores, 6992 for Intel versus 6700 for AMD, and the percentile rankings, 63rd versus 62nd, the Intel processor is the safer choice for performance parity across a broad range of Cinebench-style workloads. The AMD EPYC 72F3 remains viable for users who prioritize the platform features listed in its specifications, but the recorded data favors Intel in every head-to-head comparison. The launch MSRP of the AMD part is $2468, which is a data point for reference, but the database does not list a price for the Intel processor, so no comparative pricing analysis is possible.
