AMD EPYC 7763 vs Intel Xeon 6732P Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the AMD EPYC 7763, which wins 15 of the 17 head-to-head benchmark comparisons against the Intel Xeon 6732P. The margin of victory is not uniform, however, and the two Intel wins reveal specific workload strengths that are worth examining closely.

In the Cinebench suite, the AMD EPYC 7763 is consistently 13% ahead across all six tests. This includes both multi-core and single-core workloads: R15 multi-core scores 7247 versus 6412, R20 multi-core scores 30198 versus 26720, and R23 multi-core scores 71902 versus 63621. The single-core results follow the same pattern, with R23 single-core at 10150 versus 8981. This uniform 13% delta across every Cinebench test indicates a fundamental per-thread performance advantage rather than a scaling quirk.

The Passmark suite reveals where the AMD processor's core-count advantage becomes overwhelming. Integer math shows a 54.6% lead (516920 versus 334340), and data encryption shows the largest single delta at 89.5% (121001 versus 63848). Data compression also favors the EPYC 7763 by 21.6% (1628973 versus 1339480), and random string sorting shows a 36.9% advantage (182676 versus 133467). These are large, workload-defining gaps.

The two Intel victories are narrower but meaningful. In extended instructions, the Xeon 6732P scores 106697 versus 98294, a 7.9% advantage. In the Passmark physics test, the Intel part scores 8109 versus 7708, a 4.9% lead. Both tests suggest that the Intel architecture has specific strengths in vectorized or simulation-style workloads, even with half the core count.

The closest contest is single-thread performance. The AMD EPYC 7763 edges out the Intel Xeon 6732P by just 0.5% in Passmark single-thread (2518 versus 2506). This near-tie is notable because the Intel part has a much higher base clock (3.80 GHz versus 2.45 GHz) and boost clock (4.10 GHz versus 3.50 GHz), yet cannot convert that clock advantage into a meaningful single-thread win. The AMD architecture's IPC efficiency offsets the clock deficit almost exactly.

FAQ

Q: Which processor wins more benchmarks?

A: The AMD EPYC 7763 wins 15 of 17 head-to-head comparisons. The Intel Xeon 6732P wins only two: extended instructions and the Passmark physics test.

Q: How large is the AMD EPYC 7763's lead in multi-core rendering?

A: In Cinebench R23 multi-core, the AMD EPYC 7763 scores 71902 versus 63621 for the Intel Xeon 6732P, a 13% advantage. The same 13% delta appears across all Cinebench R15, R20, and R23 multi-core and single-core tests.

Q: Is the Intel Xeon 6732P faster in any meaningful workload?

A: Yes. It leads by 7.9% in Passmark extended instructions (106697 versus 98294) and by 4.9% in Passmark physics (8109 versus 7708). These are the only two tests where it wins, but they are real advantages for SIMD-heavy or physics-simulation code.

Q: How do the two compare in single-thread performance?

A: The AMD EPYC 7763 wins Passmark single-thread by a razor-thin 0.5% margin (2518 versus 2506). Despite the Intel part's higher clocks, the AMD processor's per-core efficiency results in a near-tie.

Q: What is the biggest single benchmark gap between the two?

A: Passmark data encryption shows the largest delta at 89.5% in favor of the AMD EPYC 7763 (121001 versus 63848). Integer math is also lopsided at 54.6% (516920 versus 334340).

Q: Do the processors have similar overall benchmark averages?

A: No. The AMD EPYC 7763 has an average benchmark score of 179916, while the Intel Xeon 6732P averages 143444. The AMD part sits 2.1% above the Intel Xeon 6740P in its rival group, while the Intel part sits 1% below the AMD EPYC 7643P in its rival group.

Architecture Differences

The two processors come from fundamentally different design generations. The AMD EPYC 7763 is built on Zen 3 architecture with the codename Milan, part of the EPYC 7003 series. It uses a 7 nm process from TSMC and packs 33,200 million transistors across 8 dies, each 81 mm². The Intel Xeon 6732P is built on Granite Rapids architecture, part of the Xeon 6 family, using Intel's 5 nm process. The database records no transistor count or die size for the Intel part.

Core and thread counts differ sharply. The AMD EPYC 7763 has 64 cores and 128 threads, double the 32 cores and 64 threads of the Intel Xeon 6732P. This core-count disparity drives many of the multi-threaded benchmark gaps, particularly in integer math and data encryption.

Cache hierarchies are also structured differently. The AMD part provides 64 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The Intel part provides 112 KB of L1 per core, 2 MB of L2 per core, and 144 MB of shared L3. The AMD processor's larger total L3 capacity (256 MB versus 144 MB) likely contributes to its data compression and sorting advantages.

Memory support shows a generational split. The AMD EPYC 7763 uses DDR4 with an eight-channel memory bus and 204.8 GB/s of bandwidth. The Intel Xeon 6732P uses DDR5, also with an eight-channel bus, but doubles the bandwidth to 409.6 GB/s. Despite having twice the memory bandwidth, the Intel part still loses most memory-sensitive benchmarks in the recorded data.

PCIe connectivity differs as well. The AMD processor provides Gen 4 with 128 lanes (CPU only), while the Intel processor provides Gen 5 with 136 lanes (CPU only). The Intel part also lists integrated graphics as "N/A," while the AMD part has no integrated graphics field at all.

Process node and foundry also separate the two: TSMC's 7 nm for AMD versus Intel's 5 nm for Intel. The Intel part is newer, with a release date of May 2025, while the AMD part launched in March 2021. Both remain in active production.

The Verdict

The data points to a clear choice for heavily multi-threaded server workloads: the AMD EPYC 7763. Its 64 cores and 128 threads deliver a 13% Cinebench multi-core advantage, an 89.5% encryption advantage, and a 54.6% integer math advantage over the 32-core Intel Xeon 6732P. The average benchmark score of 179916 versus 143444 reinforces this dominance. Both processors sit at the 98th percentile among all CPUs, but the AMD part's absolute scores are substantially higher.

The Intel Xeon 6732P makes sense only for workloads that match its two wins: extended instruction sets and physics simulation. Its 7.9% lead in extended instructions and 4.9% lead in physics are real, but narrow. For a server that must handle a mix of general compute, encryption, compression, and rendering tasks, the AMD EPYC 7763 wins 15 of 17 direct comparisons.

Clock speed does not rescue the Intel part. Despite base clocks of 3.80 GHz versus 2.45 GHz and boost clocks of 4.10 GHz versus 3.50 GHz, the Intel processor loses single-thread performance by 0.5%. The AMD architecture's higher IPC per clock completely offsets the frequency disadvantage.

The newer Intel platform offers DDR5 and PCIe Gen 5, plus double the memory bandwidth (409.6 GB/s versus 204.8 GB/s). Those platform advantages do not translate into benchmark wins in the recorded data. For raw compute throughput, the AMD EPYC 7763 is the stronger processor.

Where Each One Wins

The AMD EPYC 7763 dominates in nearly every recorded workload category. It wins all Cinebench tests by 13%, including both single-core and multi-core variants. It wins Passmark data compression by 21.6%, data encryption by 89.5%, find prime numbers by 6.4%, floating point math by 10%, integer math by 54.6%, multithread by 13%, random string sorting by 36.9%, and single-thread by 0.5%. This is a comprehensive sweep across rendering, encryption, compression, sorting, and general arithmetic workloads.

The Intel Xeon 6732P wins exactly two tests. Passmark extended instructions shows a 7.9% advantage (106697 versus 98294), indicating that code leveraging advanced or extended instruction sets runs faster on the Intel architecture. Passmark physics shows a 4.9% advantage (8109 versus 7708), suggesting simulation or physics-engine workloads may prefer the Intel part despite its lower core count.

For mixed server deployments, the AMD EPYC 7763 is the safer choice given its 15-to-2 benchmark win record. For specialized environments where extended instructions or physics simulation dominate, the Intel Xeon 6732P offers measurable, if modest, advantages. The database also shows the AMD part has a much higher average benchmark score (179916 versus 143444), which reflects its broader overall strength across the full test suite.
