AMD EPYC 7F32 vs Intel Core i9-7940X Comparison

Where Each One Wins

The benchmark data delivers a clean split: the Intel Core i9-7940X wins every recorded head-to-head benchmark, while the AMD EPYC 7F32 wins no direct comparison in the database. That is a 6 to 0 sweep in favor of Intel across all Cinebench tests, both single-core and multi-core. The significance of this is straightforward: for raw compute throughput in the Cinebench workloads recorded, the Intel part is consistently ahead, with every single one of its victories coming by a delta of 8.8 to 8.9 percent.

However, the use-case split is not simply "Intel wins, AMD loses." The EPYC 7F32 is a server processor aimed at a different workload profile. Its strengths lie outside the Cinebench tests recorded here. The database shows the AMD part has eight-channel DDR4 memory support with a memory bandwidth of 204.8 GB/s, versus the Intel part's quad-channel 85.3 GB/s. That is a massive difference in memory throughput, and it points to workloads that are memory-bound rather than compute-bound. The EPYC also supports ECC memory, which the Intel Core i9-7940X does not, making the AMD part the choice for environments where data integrity and error correction are mandatory.

The Intel part wins on core count and thread count: 14 cores and 28 threads versus the EPYC's 8 cores and 16 threads. It also wins on boost clock, reaching 4.40 GHz versus the EPYC's 3.90 GHz. For single-threaded responsiveness and lightly threaded tasks, the Intel part has the edge in clock speed and the benchmark scores confirm it.

The EPYC 7F32 counters with a higher base clock at 3.70 GHz versus 3.10 GHz, a more advanced 7 nm process node from TSMC versus Intel's 14 nm, and a much larger total L3 cache at 128 MB versus 19.25 MB. It also offers PCIe Gen 4 with 128 lanes versus the Intel part's PCIe Gen 3 with 44 lanes. For high-bandwidth I/O, dense virtualization, or large-scale data movement, the AMD part is the better fit.

So the split is: Intel for raw single- and multi-threaded compute in the tested Cinebench workloads, AMD for memory bandwidth, ECC, cache capacity, and PCIe I/O capabilities. The Intel part is a desktop part, end-of-life, while the AMD part is an active server/workstation part. The data shows two different design philosophies, and the "winner" depends entirely on what the workload demands.

Head-to-Head Benchmarks

The head-to-head data is consistent and one-sided. In Cinebench R15 multi-core, the Intel Core i9-7940X scores 2161 against the EPYC 7F32's 1987, a win by 8.8 percent. In Cinebench R15 single-core, the Intel part scores 305 against 280, a win by 8.9 percent. That single-core margin is the largest in any test, and it reflects the Intel part's higher boost clock of 4.40 GHz versus the EPYC's 3.90 GHz.

Moving to Cinebench R20, the pattern holds exactly. Multi-core shows the Intel part at 9006 versus 8281, again 8.8 percent. Single-core shows 1271 versus 1168, again 8.8 percent. In Cinebench R23, the multi-core score is 21444 for Intel versus 19718 for AMD, a further 8.8 percent gap. Single-core R23 is 3027 versus 2783, also 8.8 percent.

The consistency of the 8.8 percent delta across every multi-core test and most single-core tests suggests a stable performance ratio between the two parts. The only outlier is the R15 single-core test, where the delta widens slightly to 8.9 percent. The Intel part wins all six recorded benchmarks, with zero wins for the AMD EPYC.

What this means in practical terms: across Cinebench, a workload that scales with core count and clock speed will favor the Intel part by a nearly uniform margin. The Intel part has 14 cores versus 8, and its boost clock is 0.50 GHz higher. The EPYC's higher base clock of 3.70 GHz versus 3.10 GHz does not rescue it in these tests, because Cinebench tends to push processors toward their boost behavior, where the Intel part has the advantage.

The database also places the Intel part among rivals with similar average scores: the AMD EPYC 7501 at 6128 (0.3 percent behind), the AMD EPYC 7272 at 6186 (0.6 percent ahead), and the AMD Ryzen Threadripper 1950X at 6231 (1.4 percent ahead). The EPYC 7F32, by contrast, sits near the AMD EPYC 7351 at 5710 (0.1 percent behind) and the Intel Core i9-7920X at 5673 (0.5 percent behind). These rival comparisons reinforce the gap: the Intel part's average score is 6147, the EPYC's is 5703, a difference of 444 points.

Specification Differences

The two processors differ in nearly every major specification category. The Intel Core i9-7940X has 14 cores and 28 threads, while the AMD EPYC 7F32 has 8 cores and 16 threads. The Intel part has a base clock of 3.10 GHz and a boost clock of 4.40 GHz. The AMD part has a base clock of 3.70 GHz and a boost clock of 3.90 GHz. So the AMD part has the higher base clock, but the Intel part has the higher boost clock by a significant margin.

Thermal design power differs as well: the Intel part is rated at 165 W, the AMD part at 180 W. The sockets are incompatible: Intel uses Socket 2066, AMD uses Socket SP3. The Intel part is a desktop-market processor, end-of-life, released on 2017-08-31. The AMD part is a server/workstation processor, still active, released on 2020-04-13.

Memory support shows a major divergence. Both support DDR4, but the Intel part is quad-channel with 85.3 GB/s bandwidth, while the AMD part is eight-channel with 204.8 GB/s. ECC memory is supported only on the AMD part. PCIe also differs: Intel is Gen 3 with 44 lanes, AMD is Gen 4 with 128 lanes. The Intel part has an unlocked multiplier; the AMD part does not.

Process node and foundry differ: Intel uses a 14 nm node at Intel, while AMD uses a 7 nm node at TSMC. The AMD part lists 15,200 million transistors and a die size of 4x 74 mm². The Intel part lists a die size of 484 mm² with no transistor count recorded.

Architecture Differences

The architectural split is stark. The Intel Core i9-7940X is built on the Skylake architecture, codenamed Skylake-X, part of the Core i9 X-Series 7th Generation. It is a 14 nm design fabricated by Intel. The AMD EPYC 7F32 is built on the Zen 2 architecture, codenamed Rome, part of the EPYC Zen 2 Rome generation. It is a 7 nm design fabricated by TSMC.

Cache layouts differ substantially. The Intel part has 64 KB of L1 per core and 1 MB of L2 per core, with 19.25 MB of shared L3. The AMD part also has 64 KB of L1 per core but only 512 KB of L2 per core, with 32 MB of L3 per die and a total of 128 MB of L3. The AMD part's total L3 cache is more than six times larger than the Intel part's shared L3.

The AMD part's 7 nm process node from TSMC gives it a transistor density advantage, which is reflected in its 15,200 million transistor count across four 74 mm² dies. The Intel part, with its 484 mm² die on 14 nm, is a large monolithic design. The AMD part uses a multi-die approach (4x 74 mm²), which is characteristic of the Rome generation's chiplet design.

Other differences: the Intel part has no integrated graphics, and neither does the AMD part. The Intel part is unlocked, the AMD part is locked. The Intel part is end-of-life, the AMD part is active. The Intel part is a desktop part, the AMD part is a server/workstation part.

The Verdict

The data points to a clear verdict for compute-focused users: the Intel Core i9-7940X wins every recorded benchmark. Across six Cinebench tests, it leads by 8.8 percent in five tests and 8.9 percent in one. Its 14 cores and 28 threads outnumber the EPYC's 8 cores and 16 threads, and its 4.40 GHz boost clock outpaces the EPYC's 3.90 GHz. The average benchmark score of 6147 versus 5703 confirms the overall edge. For users running Cinebench-style multi-threaded renders or single-threaded tasks where boost clock matters, the Intel part is the one to pick.

The AMD EPYC 7F32 is not without its own case, but it is a case built outside the benchmark results. It offers ECC memory support, which the Intel part lacks entirely. It offers eight-channel memory with 204.8 GB/s bandwidth, more than double the Intel part's 85.3 GB/s. It offers PCIe Gen 4 with 128 lanes versus Gen 3 with 44 lanes. It offers 128 MB of total L3 cache versus 19.25 MB. These are server-class features that matter for memory-bound, I/O-heavy, or data-integrity-critical workloads. The EPYC is also an active product, while the Intel part is end-of-life.

So the verdict splits by workload. If the workload is compute-heavy and fits within the Cinebench profile, the Intel Core i9-7940X is the better performer, and the data shows it winning every test by a uniform margin. If the workload is memory-bound, requires ECC, needs massive PCIe I/O, or demands the larger cache pool, the AMD EPYC 7F32 is the better fit, despite losing all recorded compute benchmarks. The 61st percentile ranking for both parts masks how differently they are built for different purposes. Choose Intel for raw compute, AMD for server infrastructure.

Both parts sit at the 61st percentile of all CPUs, but that parity is superficial. The Intel part achieves it with higher clock speeds and more cores; the AMD part achieves it with a more modern process node, far higher memory bandwidth, and a much larger cache. The benchmark data favors Intel in every direct test, but the specification data shows AMD building for a different battlefield.
