AMD Ryzen 7 9800X3D vs Intel Xeon 6507P Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split between these two eight-core, sixteen-thread processors. The Intel Xeon 6507P takes three wins in the head-to-head tests, while the AMD Ryzen 7 9800X3D dominates with twelve victories. The margin of victory, however, tells a more nuanced story than the raw win count.

The Intel Xeon 6507P's most decisive win comes in Cinebench R23 single-core, where it scores 3747 against the AMD's 2080, a massive 80.1% advantage. This is the largest delta in the entire comparison. The Xeon also wins Cinebench R23 multi-core with 26548 versus 23230, a 14.3% lead, and Cinebench R15 single-core with 377 versus 328, a 14.9% edge. These Cinebench results suggest the Intel architecture has a substantial advantage in that specific rendering workload, particularly in single-threaded execution.

The AMD Ryzen 7 9800X3D counters across nearly every other measured workload. Its largest margin is in PassMark's find prime numbers test, where it scores 423 against the Intel's 224, a 47% advantage. The AMD also leads heavily in extended instructions (38808 versus 27385, a 29.4% edge), physics (4083 versus 2935, a 28.1% lead), and Cinebench R15 multi-core (3647 versus 2676, a 26.6% advantage). In data compression, the AMD scores 468017 against the Intel's 356190, a 23.9% gap, while integer math shows a 23.8% difference (116709 versus 88877). The AMD leads by 21.9% in PassMark multithread (40009 versus 31233), 19.9% in data encryption (22158 versus 17753), 18.2% in random string sorting (48526 versus 39682), and 17.8% in both single-thread and singlethread PassMark tests (4430 versus 3643). The smallest AMD victory is in floating point math, where it scores 79456 against 69604, a 12.4% lead.

When considering average benchmark scores, the two processors sit remarkably close. The Intel Xeon 6507P records an average score of 40426, while the AMD Ryzen 7 9800X3D averages 39768. Both occupy the 87th percentile among all CPUs in the database. The Xeon's nearest rivals include the AMD Ryzen 9 7940H (40431, a 0% delta), the Intel Core Ultra X7 368H (40518, a -0.2% delta), the Intel Xeon 6369P (40327, a 0.2% delta), and the Intel Core i9-13905H (40313, a 0.3% delta). The AMD's nearest rivals include the AMD Ryzen 7 PRO 8840HS (39603, a 0.4% delta), the AMD Ryzen AI 9 365 (40048, a -0.7% delta), the AMD Ryzen AI 7 450 (39485, a 0.7% delta), and the AMD Ryzen 7 7700 (40081, a -0.8% delta). The near-zero deltas in both sets of rivals indicate both processors sit in a densely populated performance tier.

Where Each One Wins

The workload split between these two chips is stark. The Intel Xeon 6507P wins only in Cinebench tests, taking R15 single-core, R23 single-core, and R23 multi-core. The R23 multi-core victory is notable because it is the only multi-threaded test the Intel wins, suggesting its particular cache and memory configuration excels at that rendering engine's specific access patterns. The single-core Cinebench wins, especially the 80.1% margin in R23 single-core, point to a significant architectural advantage in lightly threaded rendering tasks.

The AMD Ryzen 7 9800X3D wins everywhere else. Its PassMark results cover the full spectrum of integer, floating point, encryption, compression, physics, and memory-intensive workloads. The 47% lead in prime number finding indicates strong branch prediction and integer execution capabilities. The 29.4% edge in extended instructions shows better handling of SIMD and specialized instruction sets. The physics test advantage of 28.1% suggests the AMD handles collision detection and rigid body calculations more efficiently.

For use-case planning, the data indicates the Intel Xeon 6507P suits applications built around Cinebench-style rendering pipelines, particularly those where single-threaded performance in that benchmark matters most. The AMD Ryzen 7 9800X3D fits a broader range of general computing tasks, with particular strength in data compression, encryption, and mixed integer workloads. The AMD's passmark multithread score of 40009 against the Intel's 31233 indicates better aggregate throughput in varied multi-threaded scenarios, even though the Intel wins the specific R23 multi-core test.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon 6507P uses the Granite Rapids architecture on a 5 nm process fabricated by Intel, while the AMD Ryzen 7 9800X3D uses the Zen 5 architecture on a 4 nm process fabricated by TSMC. The AMD's process advantage is reflected in its higher transistor density, with 8,315 million transistors on a 70.6 mm² die, though the Intel's transistor count and die size are not recorded in the database.

Both chips have 8 cores and 16 threads, but their cache hierarchies differ substantially. The Intel Xeon 6507P provides 112 KB of L1 cache per core, 2 MB of L2 cache per core, and 48 MB of shared L3 cache. The AMD Ryzen 7 9800X3D offers 80 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3 cache. The AMD's L3 cache is exactly double the Intel's, which likely explains its strong performance in data compression and encryption workloads where larger working sets fit in cache. The Intel's larger per-core L1 and L2 caches may contribute to its Cinebench single-core advantage.

Memory architecture differs dramatically. The Intel Xeon 6507P supports eight-channel DDR5 with a memory bandwidth of 409.6 GB/s, while the AMD Ryzen 7 9800X3D uses dual-channel DDR5 with 89.6 GB/s of bandwidth. The Intel's memory bandwidth is more than 4.5 times higher, a critical factor for server workloads. Both support DDR5 and both support ECC memory. The Intel provides 88 PCIe Gen 5 lanes from the CPU, while the AMD offers 24 lanes. The Intel is designed for the Socket 4710 platform, the AMD for Socket AM5.

The Intel Xeon 6507P has no integrated graphics, while the AMD Ryzen 7 9800X3D includes Radeon Graphics. The AMD also has an unlocked multiplier for overclocking, while the Intel's multiplier is locked. The Intel targets the server and workstation market segment, the AMD targets desktop. The Intel was released on February 23, 2025, while the AMD was released earlier on November 6, 2024. The Intel has a launch MSRP of $765, the AMD a launch MSRP of $479. The Intel's part number is SRVU5, the AMD's is 100-000001084.
