AMD EPYC 7352 vs Intel Xeon 6511P Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear overall winner: the Intel Xeon 6511P takes 14 of the 17 head-to-head tests, while the AMD EPYC 7352 wins 3. The margins, however, tell a more nuanced story than the raw win count.

In the Cinebench suite, the Intel part is consistently 20.1% ahead across R15, R20, and R23 in both single and multi-core tests. The single-core results are particularly decisive: 586 versus 488 in R15, 2442 versus 2034 in R20, and 5815 versus 4844 in R23. This consistent 20% margin indicates a fundamental architectural advantage in per-thread performance, not just a clock-speed bump.

The multi-core Cinebench results follow the same pattern. The Xeon 6511P scores 4152 in R15, 17302 in R20, and 41196 in R23, while the EPYC 7352 trails at 3458, 14411, and 34314 respectively. This is notable because the AMD chip has 24 cores versus the Intel's 16, yet still loses by a fifth in threaded rendering workloads.

The PassMark suite reveals the real story. The Intel Xeon 6511P dominates in floating-point math with a 44.7% advantage (127307 versus 87969). Physics tests show an even bigger gap at 74% (4678 versus 2688). Extended instructions favor the Intel chip by 26.2% (50730 versus 40203). Single-thread performance is also a strong Intel win at 28.6% (2545 versus 1979).

The AMD EPYC 7352 wins where core count matters. Data compression goes to AMD by 3% (660712 versus 640808). Data encryption is its biggest win at 29.3% ahead (44426 versus 31429). Random string sorting favors AMD by 2.1% (69231 versus 67809). These three wins share the common thread of heavily parallelizable, memory-latency-tolerant workloads.

The two chips are nearly tied on find-prime-numbers, with Intel ahead by just 2.3% (308 versus 301). The Intel also wins the multithread test by 13.2% (45687 versus 40370) and integer math by 9.4% (162524 versus 148605).

A: The AMD EPYC 7352 has 128 MB of shared L3 cache, while the Intel Xeon 6511P has 72 MB shared L3. The AMD also has a different L2 design: 512 KB per core versus Intel's 2 MB per core.

Q: Do both CPUs support eight-channel memory?

A: Yes, both use an eight-channel memory bus. However, the Intel Xeon 6511P supports DDR5 with a bandwidth of 409.6 GB/s, while the AMD EPYC 7352 uses DDR4 with 204.8 GB/s.

Architecture Differences

The two processors come from different design eras and philosophies. The Intel Xeon 6511P is built on the Granite Rapids architecture using a 5 nm process from Intel. The AMD EPYC 7352 uses the Zen 2 architecture on a 7 nm process from TSMC.

The Intel chip is a 2025 product, while the AMD launched in August 2019. This 5-year gap is visible in the transistor count: the AMD EPYC 7352 has 15,200 million transistors across four 74 mm² dies, whereas the Intel's die size and transistor count are not recorded in the database.

Cache hierarchy differs significantly. The Intel Xeon 6511P has 112 KB of L1 per core, 2 MB of L2 per core, and 72 MB of shared L3. The AMD EPYC 7352 has 96 KB of L1 per core, 512 KB of L2 per core, and 32 MB per die for a total of 128 MB of L3. The Intel's larger per-core L2 suggests a more aggressive prefetcher design, while AMD's larger total L3 helps with data-heavy workloads.

Memory architecture also diverges. The Intel uses DDR5 with 409.6 GB/s bandwidth, exactly double the AMD's DDR4 figure of 204.8 GB/s. Both support ECC, which is expected for server CPUs.

PCIe capabilities differ as well. The Intel Xeon 6511P offers Gen 5 with 136 lanes, while the AMD EPYC 7352 provides Gen 4 with 128 lanes. The Intel has both a newer PCIe generation and more lanes.

The two chips also have different sockets: Intel Socket 4710 for the Xeon 6511P and AMD Socket SP3 for the EPYC 7352. Neither has an unlocked multiplier, and the Intel has no integrated graphics while the AMD's is not listed.

Specification Differences

The core and thread counts are the most obvious difference: 16 cores and 32 threads for the Intel, versus 24 cores and 48 threads for the AMD. Base clocks are identical at 2.30 GHz. The boost clocks differ substantially: the Intel reaches 4.20 GHz, while the AMD tops out at 3.20 GHz, a 1.0 GHz gap that explains the single-thread results.

Thermal design power is nearly identical: 150 W for the Intel and 155 W for the AMD. Both draw essentially the same power budget, making the Intel's performance advantage all the more significant per watt.

The process nodes differ: 5 nm for Intel versus 7 nm for AMD. The Intel is manufactured in-house, while AMD uses TSMC. The AMD carries 15,200 million transistors on 4x 74 mm² dies; the Intel's transistor count and die size are not recorded.

Cache is a mixed story. The Intel has a much larger per-core L1 (112 KB versus 96 KB) and L2 (2 MB versus 512 KB). The AMD has a larger total L3 at 128 MB versus the Intel's 72 MB, but it is split per die.

Memory bandwidth is exactly double on the Intel: 409.6 GB/s versus 204.8 GB/s. Both are DDR5 versus DDR4, and both use eight channels. PCIe lanes are 136 on Intel versus 128 on AMD, and the generations are Gen 5 versus Gen 4.

The release dates and launch MSRPs are part of the spec sheet. The Intel Xeon 6511P launched on February 23, 2025 with a launch MSRP of $815. The AMD EPYC 7352 launched on August 6, 2019 with a launch MSRP of $1350.

Where Each One Wins

The Intel Xeon 6511P wins overwhelmingly in single-threaded and lightly threaded workloads. The 20% lead in Cinebench R15, R20, and R23 single-core tests, plus a 28.6% advantage in PassMark single-thread, makes it the clear choice for any application that relies on per-core performance. This includes physics simulations (74% ahead), floating-point math (44.7% ahead), and extended instruction workloads (26.2% ahead).

The Intel also handles multithreaded workloads better than its core count suggests. It wins Cinebench R23 multicore by 20.1% and PassMark multi-thread by 13.2%, despite having only 16 cores versus the AMD's 24. The higher boost clock and newer architecture close the thread-count gap, turning what should be a disadvantage into a win.

The AMD EPYC 7352 wins in specific data processing tasks. Its 128 MB L3 cache and 24 cores make it strong for data compression (3% ahead) and random string sorting (2.1% ahead). The encryption win is the most significant: 29.3% ahead, likely due to the larger cache and specialized instructions. These are all workloads that benefit from massive parallel data flow rather than raw clock speed or single-thread efficiency.

The AMD chip also wins on total core count, making it a candidate for environments where more threads are needed regardless of per-thread performance. However, the benchmark data shows the Intel achieves better multithreaded results despite fewer cores.

The Verdict

The data points clearly toward the Intel Xeon 6511P for most server and workstation workloads. It wins 14 of 17 head-to-head comparisons, often by double-digit margins. The 20.1% advantage across all Cinebench tests is consistent and reliable, not a single-test anomaly. The 74% gap in physics and 44.7% in floating-point math are decisive for scientific and engineering workloads.

For anyone running render, simulation, or single-threaded application tasks, the Intel Xeon 6511P is the obvious pick. The 4.20 GHz boost clock, double the memory bandwidth, and newer architecture deliver measurable wins across the board. The launch MSRP of $815 is the data point in the pack, and the performance lead makes it the stronger option.

The AMD EPYC 7352 should be chosen only where its specific strengths matter. If the workload is dominated by encryption, data compression, or random string sorting, the AMD wins. The 29.3% encryption lead and 128 MB L3 cache are meaningful for such tasks. It also offers 24 cores for massively parallel jobs that do not hit the Intel's strengths.

However, the AMD's wins are narrower than the Intel's. The compression and string-sorting margins are around 3% or less, while the Intel's wins are often 20% or more. The AMD's only large victory is encryption.

The average benchmark scores tell the same story: the Intel Xeon 6511P averages 71051 versus the AMD EPYC 7352's 68118, a 4.3% overall gap. Both chips sit in the 94th percentile of all CPUs, so either is a top-tier performer. But the Intel Xeon 6511P is faster in more tests, by larger margins, and does so with a lower TDP. The database's verdict is straightforward: the Intel Xeon 6511P is the better CPU for the majority of server use cases, while the AMD EPYC 7352 is a niche pick for encryption and cache-heavy data tasks.
