AMD EPYC 7513 vs Intel Xeon 6527P Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive picture: the Intel Xeon 6527P wins 15 of the 17 recorded head-to-head tests, with the AMD EPYC 7513 claiming only 2. The margin is not subtle. Across all six Cinebench tests, the Intel part leads by a uniform 25.5% delta. In Cinebench R23 multi-core, the Xeon 6527P scores 63,278 against the EPYC 7513’s 50,431. Single-core R23 shows 8,933 versus 7,119, reinforcing that the Intel advantage is not purely a matter of core count.

The most lopsided result comes in PassMark physics, where the Xeon 6527P scores 8,037 against 5,118, a 57% delta. This indicates a substantial per-thread throughput advantage in simulation workloads. PassMark single-thread performance follows a similar pattern: 3,539 versus 2,479, a 42.8% gap. The Intel chip also dominates prime number finding, scoring 508 versus 380, a 33.7% lead, and floating-point math, 195,005 versus 151,713, a 28.5% advantage. Extended instruction set performance shows a 26.8% delta, with 71,600 versus 56,451.

The AMD EPYC 7513’s two wins are narrow but real. In data encryption, it scores 63,628 versus 60,333, a 5.2% edge. In integer math, it posts 272,145 versus 268,985, a 1.2% margin. These are the only workloads where the Zen 3 architecture gets ahead, and both are specific compute patterns rather than general-purpose throughput. The Intel part counters with a 10.6% lead in data compression, 1,030,818 versus 932,240, and a 25.7% edge in random string sorting, 131,597 versus 104,660. The overall passmark multithread score favors Intel by 25.5%, 74,445 versus 59,331.

Looking at the broader database context, the Xeon 6527P holds an average benchmark score of 115,190, placing it in the 97th percentile of all CPUs. Its nearest rivals include the Intel Xeon 658X at 116,060, a 0.7% gap, and the AMD EPYC 9255 at 116,388, a 1% gap. The EPYC 7513’s average is 102,244, also in the 97th percentile, but its closest competitor is the AMD EPYC 8324P at 103,329, a 1.1% difference. The two processors are not in the same performance tier according to the aggregate data, despite sharing the same percentile ranking.

Architecture Differences

The two processors come from entirely different design schools. The Intel Xeon 6527P uses the Granite Rapids architecture, built on a 5 nm process at Intel’s own foundry. The die size is 598 mm². The AMD EPYC 7513 uses the Zen 3 architecture, codenamed Milan, fabricated by TSMC on a 7 nm node. Its physical package consists of 8 chiplets, each 81 mm², totaling 33,200 million transistors. This is a fundamental difference in approach: Intel uses a monolithic die, while AMD uses a chiplet design.

Cache hierarchies diverge sharply. The Intel part allocates 112 KB of L1 and 2 MB of L2 per core, with a massive 144 MB of shared L3. The AMD part has 64 KB of L1 and 512 KB of L2 per core, with 128 MB of shared L3. The Intel L3 is 16 MB larger, and its per-core L2 is four times larger than AMD’s. These differences matter for workloads that repeatedly access the same data sets.

Memory support is another major split. The Intel Xeon 6527P supports DDR5 memory across an eight-channel bus, delivering a peak bandwidth of 409.6 GB/s. The AMD EPYC 7513 uses DDR4 across an eight-channel bus, with a peak bandwidth of 204.8 GB/s. That is exactly double the theoretical bandwidth for Intel, a factor that shows up in memory-intensive workloads like data compression and random string sorting. PCIe connectivity also differs: Intel offers Gen 5 with 88 lanes from the CPU, while AMD offers Gen 4 with 128 lanes. AMD has more total lanes, but Intel has the newer generation.

The Intel part has a boost clock of 4.20 GHz and a base clock of 3.00 GHz. The AMD part boosts to 3.65 GHz with a 2.60 GHz base. The Intel clocks are higher across the board, which helps explain its single-thread dominance. The process node difference, 5 nm versus 7 nm, is a likely contributor to the Intel clock advantage. Both processors support ECC memory, and neither has an unlocked multiplier. The Intel part is built for Socket 4710, while AMD uses Socket SP3.

Specification Differences

The core counts differ: Intel has 24 cores and 48 threads, AMD has 32 cores and 64 threads. The Intel base clock is 3.00 GHz versus 2.60 GHz for AMD. The Intel boost clock is 4.20 GHz versus 3.65 GHz for AMD. Thermal design power also differs: Intel is rated at 255 W, AMD at 200 W. The Intel part draws more power but delivers higher performance per clock in most tests.

The process nodes are different: Intel is on 5 nm, AMD on 7 nm. The foundry is Intel for the Xeon and TSMC for the EPYC. The die size is 598 mm² for Intel, while AMD uses eight 81 mm² chiplets. Transistor count is only listed for AMD, at 33,200 million. The L1 cache per core is 112 KB on Intel versus 64 KB on AMD. L2 per core is 2 MB on Intel versus 512 KB on AMD. L3 is 144 MB shared on Intel versus 128 MB shared on AMD.

Memory support is DDR5 for Intel and DDR4 for AMD. Memory bandwidth is 409.6 GB/s for Intel versus 204.8 GB/s for AMD. PCIe generation is Gen 5 for Intel and Gen 4 for AMD, with lane counts of 88 and 128, respectively. The release dates differ significantly: the Intel Xeon 6527P launched on 2025-02-23, while the AMD EPYC 7513 launched on 2021-03-14. The part numbers are SRVNY for Intel and 100-000000334100-100000334WOF for AMD. The Intel launch MSRP is $2878, and the AMD launch MSRP is $2840.

Where Each One Wins

The Intel Xeon 6527P is the clear choice for general-purpose compute density. Its 25.5% lead across every Cinebench test, from R15 to R23, in both single and multi-core modes, indicates a broad advantage in rendering and content creation workloads. The 42.8% single-thread lead in PassMark makes it the better option for lightly threaded applications, database queries, and any software that relies on high per-core frequency. The 57% physics win points to simulation and engineering workloads where per-thread efficiency is paramount. The 33.7% edge in prime number finding and 28.5% lead in floating-point math make it suitable for scientific computing, financial modeling, and any task with heavy arithmetic. The doubled memory bandwidth, 409.6 GB/s versus 204.8 GB/s, gives it a decisive edge in data compression and random string sorting, where memory throughput is often the bottleneck.

The AMD EPYC 7513 wins in two specific niches. Its 5.2% lead in data encryption suggests an advantage in cryptography, secure communications, and workloads that heavily use AES or similar instructions. Its 1.2% edge in integer math points to applications with heavy integer arithmetic, such as certain compression algorithms, database indexing, or legacy code paths. The EPYC also has more cores, 32 versus 24, and more PCIe lanes, 128 versus 88, which could matter for systems with many NVMe drives or GPU accelerators. For workloads that are explicitly parallel across many cores and do not require high per-core clocks, the AMD part offers a viable alternative. However, the benchmark data shows that in practice, the Intel part’s architecture and memory subsystem overcome the core deficit in almost every measured scenario.

For a system builder choosing between these two, the Intel Xeon 6527P is the higher-performing part in the vast majority of tested workloads. The AMD EPYC 7513 remains relevant only for specialized tasks like encryption-heavy services or integer-bound processes. The aggregate scores confirm the split: Intel averages 115,190, AMD averages 102,244, a roughly 12.7% difference that the head-to-head results echo. The Intel part is newer, faster per clock, and has a more capable memory system. The AMD part is older, uses slower memory, but offers more cores and more PCIe lanes. The database measurements favor Intel in almost every category that matters for general server and workstation use.
