AMD EPYC 8324P vs Intel Xeon 6527P Comparison

Head-to-Head Benchmarks

The recorded data presents a strikingly one-sided head-to-head comparison. The Intel Xeon 6527P wins 16 of the 17 benchmark comparisons, with the AMD EPYC 8324P taking a single narrow victory. The scale of the Intel advantage varies dramatically by workload, from a slim 5.1% edge to a commanding 73.3% lead.

In Cinebench testing, the Xeon 6527P is consistently ahead by approximately 30.3% across all four metrics: single-core and multi-core in both R15 and R20, plus R23 multi-core. The R23 single-core result shows the same 30.3% delta, with Intel scoring 8933 against AMD's 6855. This uniformity suggests a fundamental architectural advantage rather than workload-specific optimization.

The PassMark suite reveals the true breadth of the performance gap. The largest divergence appears in physics calculations, where the Xeon 6527P scores 8037 versus the EPYC's 4637, a delta of 73.3%. Prime number finding shows a 46.4% advantage (508 versus 347), and single-thread performance is 49.5% higher (3539 versus 2367). Floating-point math also heavily favors Intel at 40.3% (195005 versus 139022).

Other PassMark metrics show more modest Intel leads. Extended instructions sit 18.7% higher (71600 versus 60304), random string sorting is 15.8% ahead (131597 versus 113610), and integer math shows an 8.3% edge (268985 versus 248447). Data compression is closest among Intel wins at 5.1% (1030818 versus 980907).

The AMD EPYC 8324P's only victory comes in data encryption, where it scores 63195 against Intel's 60333, a 4.5% advantage. This is a notable result, as encryption workloads often respond to different microarchitectural features than general compute tasks.

Looking at the broader database context, the Xeon 6527P's average benchmark score is 115190, placing it in the 97th percentile of all CPUs. Its nearest rivals include the Intel Xeon 658X at 116060 (0.7% higher) and the AMD EPYC 9255 at 116388 (1% higher). The EPYC 8324P averages 103329, also in the 97th percentile, with the AMD EPYC 7513 at 102244 (1.1% lower) and the AMD Ryzen Threadripper PRO 9955WX at 101041 (2.3% lower) as its closest competitors.

Architecture Differences

The two processors represent fundamentally different design philosophies. The Intel Xeon 6527P uses Granite Rapids architecture on a 5 nm process fabricated by Intel, featuring 24 cores and 48 threads. The AMD EPYC 8324P employs Zen 4c architecture on a 5 nm process from TSMC, with 32 cores and 64 threads. Despite having fewer cores, the Intel part delivers higher performance in nearly every measured workload.

Clock speeds differ substantially. The Xeon 6527P runs at 3.00 GHz base and boosts to 4.20 GHz, while the EPYC 8324P operates at 2.65 GHz base and 3.00 GHz boost. This 1.2 GHz boost advantage for Intel explains part of the single-thread dominance, but the multi-core results suggest the architecture extracts more from each core as well.

Cache hierarchies present another key divergence. Intel allocates 112 KB of L1 and 2 MB of L2 per core, with 144 MB of shared L3. AMD provides 64 KB L1 and 1 MB L2 per core, with 128 MB shared L3. The larger per-core caches on the Intel side likely contribute to its strong showing in cache-sensitive workloads like prime number finding and physics calculations.

Memory subsystems differ significantly. The Xeon 6527P supports eight-channel DDR5 with 409.6 GB/s bandwidth, while the EPYC 8324P uses six-channel DDR5 at 230.4 GB/s. This 179.2 GB/s bandwidth gap directly impacts data-intensive operations and helps explain Intel's advantage in multi-core throughput tests.

PCIe connectivity shows the AMD part with more lanes: 96 Gen 5 lanes versus Intel's 88. Both support ECC memory. The Intel die measures 598 mm², while AMD uses four 73 mm² chiplets totaling 35,500 million transistors. Socket platforms differ as well, with Intel on Socket 4710 and AMD on Socket SP6.

Where Each One Wins

The Intel Xeon 6527P is the clear choice for compute-heavy workloads that dominate typical server benchmarks. Its 30.3% advantage across all Cinebench multi-core tests positions it strongly for rendering, simulation, and other throughput-oriented tasks. The 73.3% physics win indicates particular strength in scientific computing and physical simulation workloads.

Single-thread performance favors Intel decisively, with a 49.5% lead in PassMark single-thread testing and a 30.4% edge in Cinebench R15 single-core. This makes the Xeon 6527P better suited for latency-sensitive applications, legacy single-threaded code, and scenarios where per-core performance is critical.

The 46.4% advantage in prime number finding and 40.3% lead in floating-point math suggest Intel has superior arithmetic execution capabilities. These results point toward mathematical modeling, financial analytics, and computational research applications. The 18.7% extended instructions advantage further supports workloads using SIMD or specialized instruction sets.

Data compression favors Intel by 5.1%, making it marginally better for database compression, archival tasks, and data warehousing operations. Integer math shows an 8.3% edge, relevant for general-purpose business applications and transactional workloads.

The AMD EPYC 8324P wins only in data encryption, with a 4.5% advantage. This makes it the better option for cryptographic operations, secure communications processing, and VPN or TLS termination workloads. The result suggests AMD's architecture handles certain encryption algorithms more efficiently, potentially through better hardware acceleration integration.

The Verdict

The benchmark data is unambiguous: the Intel Xeon 6527P outperforms the AMD EPYC 8324P in 16 of 17 recorded tests, often by substantial margins. For organizations prioritizing raw compute performance across rendering, scientific computing, and general server workloads, the Intel part delivers consistently higher scores. The 30.3% uniform advantage in Cinebench tests indicates broad multi-core superiority despite Intel having 8 fewer cores and 16 fewer threads than AMD.

However, the AMD EPYC 8324P offers a specific advantage in encryption workloads and brings more PCIe lanes (96 versus 88) for expandability. Its lower thermal design power of 180 W compared to Intel's 255 W may also factor into deployment decisions where power constraints matter, though the recorded data does not directly compare thermals.

The average benchmark scores place the Xeon 6527P at 115190, approximately 11.5% higher than the EPYC 8324P's 103329. Both processors sit in the 97th percentile of all CPUs, indicating they are both high-end parts, but the Intel product occupies a higher performance tier within that elite group.

The Intel Xeon 6527P trades core count and thread count for higher clocks, larger caches, and greater memory bandwidth. The AMD EPYC 8324P counters with more cores, lower power consumption, and additional PCIe lanes. The Intel part's launch MSRP of $2878 is higher than AMD's $1895, but the benchmark results show a substantial performance gap favoring Intel across nearly all measured workloads.
