AMD Ryzen 9 7950X vs Intel Xeon 6515P Comparison

Head-to-Head Benchmarks

The head-to-head data reveals a decisive split between the AMD Ryzen 9 7950X and the Intel Xeon 6515P. Out of 15 shared benchmark tests, the AMD processor wins 10 and the Intel processor wins 5. The margin of victory is the key differentiator, with the AMD Ryzen 9 7950X often winning by large double-digit percentages, while the Intel Xeon 6515P takes its wins either by a narrow margin or in specific single-threaded tests.

The largest win for the AMD Ryzen 9 7950X comes in the PassMark data encryption test, where it scores 49,336 against Intel's 30,476, a 61.9% advantage. This is followed closely by the PassMark integer math test, where AMD's 225,603 beats Intel's 147,047 by 53.4%. The PassMark random string sorting test also heavily favors the AMD chip, with a score of 98,501 versus 64,425, a 52.9% lead. In the Cinebench R15 multicore test, the AMD Ryzen 9 7950X posts 5,947.5 versus Intel's 3,885, a 53.1% lead. The PassMark multithread test shows a 37.8% advantage for AMD (62,478 versus 45,350), and the PassMark data compression test shows a 41% advantage (835,923 versus 592,645). Even in the PassMark single-thread test, the AMD processor leads with 4,266 versus 2,855, a 49.4% margin.

The Intel Xeon 6515P, however, dominates the single-core Cinebench tests. In Cinebench R23 single-core, Intel scores 5,442 versus AMD's 2,000, a staggering 63.2% lead. In Cinebench R15 single-core, Intel scores 548 versus AMD's 315.5, a 42.4% lead. Intel also wins the Cinebench R23 multicore test, but by a much slimmer margin: 38,547 versus 36,523, a 5.3% lead. Other Intel wins include PassMark find prime numbers (385 versus 337, a 12.5% lead) and PassMark physics (3,829 versus 3,102, a 19% lead).

The Verdict

The data points to two very different performance profiles. The AMD Ryzen 9 7950X is the clear winner for general-purpose, desktop, and most workstation workloads. Its victories in integer math, data compression, data encryption, floating-point math, random string sorting, and multithreaded tests demonstrate broad superiority in everyday computing and content-creation tasks. The 49.4% lead in PassMark single-thread further solidifies its position as the better choice for responsiveness and lightly-threaded applications.

The Intel Xeon 6515P, while losing the overall benchmark count, shows exceptional strength in Cinebench single-core tests. The 63.2% lead in Cinebench R23 single-core is not a trivial gap; it suggests that the Intel architecture has a significant advantage in raw per-core performance in certain rendering workloads. However, this does not translate into a win in the newer Cinebench R23 multicore test, where it only beats AMD by 5.3%. The Intel processor also wins in the PassMark physics and find prime numbers tests, indicating a specific strength in certain computational patterns.

The overall average benchmark scores reflect this split. The AMD Ryzen 9 7950X has an average benchmark score of 69,515, with a percentile ranking of 94. The Intel Xeon 6515P has an average benchmark score of 67,006, with a percentile ranking of 93. The AMD chip is 2,509 points ahead on average. The nearest rivals for the AMD chip include the Intel Core i7-14700K (0.2% higher average score) and the AMD EPYC 9115 (0.3% higher), showing that the 7950X is competitively positioned within its own performance tier. The Intel Xeon's closest rival is the AMD EPYC 4465P (0.1% higher), indicating that its performance level is also tightly contested.

Where Each One Wins

The AMD Ryzen 9 7950X wins in the areas that matter most for a desktop processor. Its 53.4% lead in integer math and 41% lead in data compression suggest it is superior for software compilation, file archiving, and general productivity tasks. The 61.9% lead in data encryption makes it a strong choice for security-related workloads and VPNs. The 52.9% lead in random string sorting and 37.8% lead in multithreaded performance point to advantages in database operations and parallel computing. Its 49.4% lead in PassMark single-thread means snappier application launches and better performance in legacy software that relies on a single fast core.

The Intel Xeon 6515P wins in Cinebench single-core tests by a massive margin, which is its most distinguishing feature. This suggests it holds an advantage in applications that are heavily dependent on single-threaded rendering performance, such as certain 3D modeling and animation tools. Its 19% lead in PassMark physics could indicate an edge in simulation and physics-based workloads. The 12.5% lead in find prime numbers suggests a possible advantage in certain mathematical and cryptographic computations. The narrow 5.3% win in Cinebench R23 multicore shows that despite its single-core strength, it does not scale that advantage across all cores in that workload.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 9 7950X uses the Zen 4 architecture with the Raphael codename, while the Intel Xeon 6515P uses the Granite Rapids architecture. Both are fabricated on a 5 nm process node, but AMD uses TSMC as the foundry, whereas Intel uses its own foundry. The AMD chip has a die size of 2x 71 mm² with 13,140 million transistors, while the die size and transistor count for the Intel Xeon are not recorded in the database.

The cache structures differ significantly. The AMD Ryzen 9 7950X has 64 KB of L1 cache per core and 1 MB of L2 cache per core, with a shared 64 MB L3 cache. The Intel Xeon 6515P has a larger L1 cache at 112 KB per core and a larger L2 cache at 2 MB per core, with a shared L3 cache of 72 MB. This gives the Intel chip a total cache advantage in the L2 and L3 levels, which may contribute to its single-core performance wins.

Memory support also diverges. Both support DDR5 memory, but the AMD Ryzen 9 7950X uses a dual-channel memory bus with a bandwidth of 83.2 GB/s. The Intel Xeon 6515P uses an eight-channel memory bus with a significantly higher bandwidth of 409.6 GB/s. Both support ECC memory. The PCI Express capabilities differ as well: the AMD chip has Gen 5 with 24 lanes (CPU only), while the Intel chip has Gen 5 with 88 lanes (CPU only). The AMD Ryzen 9 7950X includes integrated Radeon Graphics, while the Intel Xeon 6515P has no integrated graphics. The AMD chip has an unlocked multiplier, while the Intel chip does not.

Specification Differences

The most obvious specification difference is the clock speed. The AMD Ryzen 9 7950X has a base clock of 4.50 GHz and a boost clock of 5.70 GHz. The Intel Xeon 6515P has a much lower base clock of 2.30 GHz and a boost clock of 3.80 GHz. Despite this, the Intel chip has a lower TDP of 150 watts compared to the AMD chip's 170 watts.

The socket types are entirely different. The AMD Ryzen 9 7950X uses AMD Socket AM5, while the Intel Xeon 6515P uses Intel Socket 4710. This means they are not interchangeable in any system.

The market segments differ. The AMD Ryzen 9 7950X is a desktop processor, while the Intel Xeon 6515P is a server/workstation processor. The launch dates are also different, with the AMD chip releasing in September 2022 and the Intel chip releasing in February 2025. The launch MSRP for the AMD Ryzen 9 7950X is $699, and the launch MSRP for the Intel Xeon 6515P is $740.

The part numbers are unique: the AMD chip is 100-000000514, and the Intel chip is SRVU6. Both processors have 16 cores and 32 threads, so the core and thread counts are identical. The production status for both is listed as Active.
