AMD EPYC 4245P vs Intel Xeon 6507P Comparison

Where Each One Wins

The recorded benchmark data splits these two server processors into distinct roles. The AMD EPYC 4245P takes 11 of the 17 head-to-head tests, while the Intel Xeon 6507P wins 6. That raw win count, however, hides the character of each victory. The AMD part dominates single-threaded workloads and several integer-focused tasks, while the Intel part pulls ahead in floating-point math, prime number generation, physics simulation, and data compression.

The AMD EPYC 4245P's most dramatic advantage appears in single-thread performance. The PassMark single-thread test shows a 25.6% lead over the Intel Xeon 6507P, a massive gap for two server chips. The Cinebench single-core results tell a similar story, with the AMD part winning R15, R20, and R23 single-core tests by 0.3% each. This pattern suggests the AMD chip is the better choice for lightly threaded workloads, database queries that depend on per-core speed, or any application where latency on a single thread matters more than raw throughput.

The Intel Xeon 6507P counters in floating-point heavy work. The PassMark floating-point math test shows Intel ahead by 16.7%, and the prime numbers test reveals a 13.8% Intel advantage. Physics simulation also favors Intel by 10.2%. These are the kinds of workloads found in scientific computing, financial modeling, and engineering simulation. Data compression also goes to Intel with a 4.7% edge, which could matter for storage servers or backup systems.

The AMD EPYC 4245P fights back in integer math with a 7% lead, and data encryption shows AMD ahead by 4%. The AMD part also wins random string sorting by 0.6%. The multithreaded PassMark score goes to Intel, but only by 0.5%, which is nearly a tie. The Cinebench multicore tests all go to AMD, though by slim margins of 0.2% to 0.3%.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD EPYC 4245P uses the Zen 5 architecture under the codename Grado, built on a 4 nm process at TSMC. The Intel Xeon 6507P uses the Granite Rapids architecture, built on a 5 nm process at Intel's own foundry. The AMD chip has 8,315 million transistors on a 70.6 mm² die, while the database records no transistor count or die size for the Intel part.

Core counts differ in an interesting way. The Intel Xeon 6507P has 8 cores and 16 threads, while the AMD EPYC 4245P has 6 cores and 12 threads. Despite having fewer cores, the AMD chip manages to keep pace in multicore Cinebench tests. This suggests the Zen 5 cores are doing more work per clock, or the higher boost clock is compensating for the core deficit.

Clock speeds tell part of the story. The AMD part has a base clock of 3.90 GHz and a boost clock of 5.40 GHz. The Intel part runs at 3.50 GHz base and 4.30 GHz boost. That 1.10 GHz boost clock advantage for AMD helps explain the 25.6% single-thread lead. The AMD chip also consumes far less power with a 65 W TDP versus 150 W for Intel, though the database does not record thermals or real-world power draw.

Cache hierarchies differ substantially. The Intel Xeon 6507P has 112 KB of L1 cache per core and 2 MB of L2 per core, compared to 80 KB L1 and 1 MB L2 for AMD. Intel also has 48 MB of shared L3 cache versus 32 MB for AMD. The larger Intel cache allocation per core makes sense given the Granite Rapids design, but it does not translate into a single-thread advantage in the recorded data.

Memory architecture shows a major divergence. Both support DDR5 and ECC memory, but the Intel part uses an eight-channel memory bus with 409.6 GB/s of bandwidth, while the AMD part uses dual-channel memory with 89.6 GB/s. That is a 4.6x bandwidth advantage for Intel, which likely explains the data compression and floating-point wins. PCIe connectivity also favors Intel with 88 Gen 5 lanes versus 24 for AMD.

The AMD EPYC 4245P includes integrated Radeon Graphics, while the Intel Xeon 6507P has no integrated graphics. The AMD part launches on Socket AM5, while Intel uses Socket 4710. Both have locked multipliers and are marked as Active in production status. The AMD release date is May 2025, about two and a half months after Intel's February 2025 launch.

Head-to-Head Benchmarks

The Cinebench suite shows remarkable parity between these two chips. In R15 multicore, the AMD EPYC 4245P scores 2682 against 2676 for Intel, a 0.2% margin. R20 multicore gives AMD 11179 versus 11150, a 0.3% edge. R23 multicore shows AMD at 26618 against 26548, again 0.3%. The single-core Cinebench tests all show AMD ahead by 0.3%. These margins are within noise, suggesting that for pure CPU rendering workloads, the two parts are effectively equivalent.

The PassMark suite reveals where the architectures truly separate. The single-thread test is the headline: AMD scores 4575 against Intel's 3643, a 25.6% blowout. This is the single largest delta in the entire comparison. The AMD part also wins integer math with 95120 versus 88877, a 7% margin. Data encryption goes to AMD at 18466 versus 17753, a 4% edge. Random string sorting is nearly tied, with AMD at 39916 and Intel at 39682, a 0.6% difference.

Intel's wins are concentrated in mathematically intensive work. Floating-point math shows Intel at 69604 against AMD's 57965, a 16.7% advantage. Prime number finding gives Intel 224 versus 193, a 13.8% lead. Physics simulation favors Intel at 2935 versus 2637, a 10.2% gap. Data compression goes to Intel at 356190 against 339408, a 4.7% margin. Extended instructions also favor Intel at 27385 versus 26547, a 3.1% edge. The PassMark multithread score goes to Intel at 31233 versus 31063, but only by 0.5%.

The overall average benchmark scores place these chips close together. The AMD EPYC 4245P has an average benchmark score of 39215, while the Intel Xeon 6507P averages 40426. The Intel part sits in the 87th percentile of all CPUs, one point above AMD's 86th percentile. Intel's nearest rival is the AMD Ryzen 9 7940H with a 0% delta, while AMD's closest competitor is the AMD Ryzen 7 PRO 8845HS at 0.3% behind.

The Verdict

The data points to a clear use-case split. For single-threaded performance and general integer workloads, the AMD EPYC 4245P is the stronger choice. The 25.6% single-thread lead is decisive, and the 7% integer math advantage reinforces that conclusion. The AMD part also wins encryption, which matters for security-sensitive applications. Its 65 W TDP and integrated Radeon Graphics make it a more flexible platform for systems that need modest graphics output without a separate GPU.

For floating-point heavy and memory bandwidth intensive workloads, the Intel Xeon 6507P is the better option. The 16.7% floating-point math lead, 13.8% prime number advantage, and 10.2% physics simulation edge are substantial. The eight-channel memory architecture with 409.6 GB/s of bandwidth gives Intel a massive data throughput advantage that the dual-channel AMD part cannot match. Data compression also favors Intel, making it suitable for storage and archival servers.

The multicore Cinebench results are essentially a draw. Both parts deliver nearly identical rendering performance despite the Intel chip having 8 cores and 16 threads against AMD's 6 cores and 12 threads. This suggests the AMD Zen 5 cores are more efficient per thread, or the boost clock advantage is closing the core count gap. The PassMark multithread score also shows only a 0.5% difference.

The launch MSRP for the AMD EPYC 4245P is $239, while the Intel Xeon 6507P has a launch MSRP of $765. The average benchmark score difference is only 3.1% in Intel's favor. The database does not record pricing analysis, but the score-to-score comparison shows the AMD part delivering nearly equivalent average performance at a different price point. The choice ultimately depends on workload character, not average scores.
