AMD EPYC 9384X vs Intel Xeon 6527P Comparison

The AMD EPYC 9384X and Intel Xeon 6527P are both 97th-percentile server processors, yet they achieve that status through strikingly different means. The EPYC 9384X, a 32-core Zen 4 Genoa-X part, leans on a massive 768 MB L3 cache, while the Xeon 6527P, a 24-core Granite Rapids-SP chip, counters with higher clock speeds and newer core architecture. Benchmark results show a clear split: Intel dominates rendering and single-threaded workloads, while AMD wins data-heavy and cryptographic tasks, making the choice heavily dependent on the specific application.

Head-to-Head Benchmarks

The most consistent pattern in the head-to-head data is Intel’s sweep of the Cinebench suite. Across all six Cinebench tests—R15, R20, and R23, each in both single-core and multi-core variants—the Xeon 6527P wins by an identical margin of 6.4%. For example, in Cinebench R23 multi-core, Intel scores 63,278 against AMD’s 59,215, and in the single-core test, Intel posts 8,933 versus 8,359. This uniformity suggests a clock-speed advantage rather than a core-count effect, as the Intel chip’s boost clock of 4.20 GHz exceeds AMD’s 3.90 GHz.

Intel’s advantage extends to PassMark’s floating-point math test, where it wins by 10.4% with a score of 195,005 versus 174,630. The Xeon also takes random string sorting by 9.2% (131,597 vs. 119,440) and the PassMark multi-thread test by 6.4% (74,445 vs. 69,665). The single-thread benchmark is Intel’s largest win at 14.8%, scoring 3,539 against AMD’s 3,015, reinforcing that the Xeon’s per-core performance is its primary weapon.

AMD’s wins are fewer but decisive in specialized areas. The EPYC 9384X crushes the Xeon in data encryption by 20.4% (72,631 vs. 60,333), a margin that points directly to its cache architecture. It also takes find prime numbers by 17.3% (596 vs. 508) and physics by 16.1% (9,332 vs. 8,037). In integer math, AMD leads by 10.7% (297,833 vs. 268,985), and data compression goes to AMD by 8.6% (1,119,983 vs. 1,030,818). The extended instructions test is close, with AMD ahead by 3.9% (74,363 vs. 71,600). Overall, Intel wins 11 of 17 head-to-head benchmarks, but AMD’s victories come in workloads where its lead is often larger in percentage terms.

Architecture Differences

The two processors are built on the same 5 nm process node but from different foundries: TSMC for AMD and Intel for the Xeon. The EPYC 9384X uses Zen 4 architecture under the Genoa-X codename, while the Xeon 6527P is Granite Rapids, part of the Xeon 6 family. Core counts differ significantly: AMD offers 32 cores and 64 threads, while Intel provides 24 cores and 48 threads—a 33% core advantage for AMD that helps offset Intel’s higher clock speeds.

Cache is where the architectures diverge most dramatically. The EPYC 9384X has 768 MB of shared L3 cache, a figure made possible by AMD’s 3D V-Cache technology, which stacks additional cache dies. Intel’s Xeon 6527P has 144 MB of shared L3, less than a fifth of AMD’s total. Per-core cache also favors Intel: 112 KB L1 and 2 MB L2 per core, versus AMD’s 64 KB L1 and 1 MB L2 per core. This means Intel has more cache closest to each core, but AMD’s massive shared pool is better for datasets that exceed per-core capacity.

Other structural differences abound. AMD uses a twelve-channel memory bus yielding 460.8 GB/s of bandwidth, while Intel uses eight channels for 409.6 GB/s—AMD has 12.5% more theoretical bandwidth. PCIe lanes also favor AMD: 128 Gen 5 lanes versus Intel’s 88. The EPYC 9384X uses AMD Socket SP5, while the Xeon uses Intel Socket 4710. Intel’s die is a monolithic 598 mm², whereas AMD’s is composed of 8 chiplets at 72 mm² each, totaling 576 mm². AMD’s transistor count is listed at 90,160 million. Intel lists no integrated graphics, and AMD has none either. Both support DDR5 memory with ECC.

Where Each One Wins

For rendering and content creation, the Xeon 6527P is the clear choice. Its Cinebench R23 multi-core score of 63,278 is 6.4% ahead of AMD’s 59,215, and every Cinebench variant shows the same margin. The Xeon’s floating-point math win of 10.4% further cements its position for scientific computing and physics simulations that rely on FP32 or FP64 throughput. The single-thread lead of 14.8% makes it better for lightly threaded applications like legacy database queries or single-threaded scripting workloads. Its boost clock of 4.20 GHz is the highest of the two, which explains these wins.

The EPYC 9384X is the pick for data-centric workloads. Its 20.4% lead in data encryption is enormous and suggests hardware or cache advantages for cryptographic operations. The 17.3% win in prime-number finding indicates strong integer division and modular arithmetic performance. Integer math, up 10.7%, covers general business logic, and data compression’s 8.6% win benefits storage and database compression tasks. The physics test, up 16.1%, is interesting because it contradicts the floating-point result—but physics often involves collision detection and rigid-body dynamics that are integer-heavy. AMD’s 768 MB L3 cache is the likely enabler, allowing larger working sets to stay on-die.

The multi-thread PassMark score goes to Intel by 6.4%, despite AMD having 8 more cores. This is a crucial finding: Intel’s per-core efficiency outweighs AMD’s core-count advantage in this synthetic aggregate. However, AMD’s average benchmark score is 120,427 versus Intel’s 115,190, meaning AMD wins more total performance across the full test suite. The EPYC 9384X also has a higher TDP at 320W versus Intel’s 255W, which should be considered for power-constrained racks.
