Intel Xeon 6960P vs Intel Xeon 6980P Comparison

Head-to-Head Benchmarks

The head-to-head data is decisively lopsided. Out of 14 recorded benchmark comparisons, the Intel Xeon 6960P wins 13, while the Intel Xeon 6980P takes only 1. The magnitude of the 6960P's victories ranges from moderate to overwhelming.

The most striking pattern is in the Cinebench multi-core suite. Across all three versions (R15, R20, R23), the 6960P posts identical deltas of 75.8% ahead of the 6980P. The raw scores tell the story: 11194 vs 6367 in R15, 46645 vs 26533 in R20, and 111060 vs 63175 in R23. This consistency across rendering workloads suggests a fundamental throughput advantage, not a workload-specific quirk.

The single-thread gap is even larger in percentage terms. PassMark single-thread scores show the 6960P at 3287 versus 1681 for the 6980P, a 95.5% advantage. The same delta appears in the duplicate passmark_singlethread entry. This is a massive per-core performance difference, and it carries implications for any workload that cannot fully saturate all available threads.

The most extreme delta in the entire comparison appears in PassMark physics. The 6960P scores 24937 against 3350, a 644.4% advantage. This is the single biggest relative win for either processor. Physics simulations often depend heavily on single-core efficiency and cache behavior, and the data reflects a stark gap in that domain.

Prime number finding shows a similarly lopsided result, though less extreme: 1484 vs 555, a 167.4% delta in favor of the 6960P. This workload is traditionally sensitive to integer throughput and memory latency, both of which appear to favor the smaller-core-count chip.

Data compression favors the 6960P by 18.3% (2797724 vs 2364519), while data encryption shows a 29.4% delta (162013 vs 125246). Integer math is 14.2% ahead on the 6960P (727750 vs 637476), and floating-point math is closer still at 5.1% (527473 vs 501720). Random string sorting rounds out the 6960P's wins with a 54.4% margin (371795 vs 240792).

The sole victory for the 6980P comes in extended instructions, where it scores 214794 versus 193404, a 10% advantage. This is the only workload in the entire dataset where the 128-core part outperforms the 72-core part. The PassMark multithread score also goes to the 6960P by 75.8% (130659 vs 74324), matching the Cinebench deltas exactly.

The average benchmark score in the database reinforces this hierarchy: the 6960P averages 365194, while the 6980P averages 251516. The 6960P sits at the 100th percentile of all CPUs, whereas the 6980P is at the 99th.

Where Each One Wins

The Intel Xeon 6960P is the clear choice for the vast majority of compute-heavy scenarios. Its 75.8% advantage across all three Cinebench versions makes it the superior part for rendering, 3D modeling, and any multi-threaded creative workload that relies on CPU rendering. The 167.4% lead in prime number finding points to strength in integer-heavy computational tasks, cryptography, and number-crunching simulations.

The 644.4% delta in PassMark physics is particularly notable. Physics simulation in scientific computing, game server physics, and engineering analysis all benefit from the 6960P's architecture. The 95.5% single-thread lead means the 6960P also excels in lightly-threaded workloads, database queries, and any application where a single core must perform at maximum efficiency.

Data compression and encryption workloads favor the 6960P by 18.3% and 29.4%, respectively. This makes it the better option for storage servers, backup systems, and secure communication infrastructure. The 54.4% advantage in random string sorting further supports use cases involving text processing, log analysis, and data indexing.

The Intel Xeon 6980P has exactly one clear domain: extended instruction sets. Its 10% lead in PassMark extended instructions suggests an edge in workloads that leverage specialized SIMD or cryptographic instruction extensions. This could include certain scientific libraries, media codecs, or specific enterprise software that has been optimized for those instruction paths.

For general multithreaded throughput, the 6980P cannot compete. The 75.8% deficit in PassMark multithread and the same margin in all Cinebench tests make it unsuitable for most high-performance computing roles.

Specification Differences

The two processors share a common platform foundation but diverge significantly in core configuration and cache allocation. Both use the Intel Socket 7529, both have a TDP of 500, and both are built on the same Granite Rapids architecture. The process node is 5 nm from Intel for both, and both use a three-die setup with each die measuring 598 mm².

The core counts are the primary differentiator. The 6960P has 72 cores and 144 threads, while the 6980P has 128 cores and 256 threads. This is a 56-core, 112-thread difference in favor of the 6980P. Base clock speeds differ substantially: the 6960P runs at 2.70 GHz, while the 6980P operates at 2.00 GHz. The boost clocks are identical at 3.90 GHz.

Cache hierarchies differ as well. Both have 112 KB of L1 cache per core and 2 MB of L2 cache per core. The shared L3 cache, however, is 432 MB on the 6960P versus 504 MB on the 6980P. Despite having 56 fewer cores, the 6960P's L3 is 72 MB smaller, meaning per-core L3 allocation is dramatically higher on the 6960P.

Memory support is identical: DDR5 with a twelve-channel bus and 614.4 GB/s of bandwidth. Both support ECC memory and provide Gen 5 PCIe with 96 lanes from the CPU. Neither has integrated graphics or an unlocked multiplier. The release dates match at 2024-09-23, and both are listed as Active in production.

The launch MSRP is $9625 for the 6960P and $12460 for the 6980P.

Architecture Differences

Both processors are built on the Granite Rapids architecture, specifically the Xeon 6 (Granite Rapids-AP) generation. They share the same 5 nm process node, the same Intel foundry, and the same three-die design with each die at 598 mm². The socket is identical, and both support the same memory and PCIe configurations.

The architectural differences are therefore primarily in core count and cache organization. The 6980P packs 128 cores into the same physical package, which explains its lower 2.00 GHz base clock versus the 6960P's 2.70 GHz. Higher core density with the same 500 TDP budget necessarily limits per-core power and frequency headroom.

The cache allocation strategy diverges meaningfully. While both use 112 KB L1 and 2 MB L2 per core, the shared L3 pool is 504 MB on the 6980P versus 432 MB on the 6960P. With 128 cores, the 6980P has roughly 3.94 MB of L3 per core. The 6960P, with 72 cores, has exactly 6 MB of L3 per core. This 52% difference in per-core L3 capacity likely contributes to the 6960P's superior single-thread and physics performance.

The boost clocks are identical at 3.90 GHz, but the base clocks differ by 0.70 GHz. This suggests that under sustained all-core loads, the 6960P can maintain higher frequencies, while the 6980P must drop further to stay within its thermal and power envelope. The benchmark data supports this interpretation: despite having only 56% of the core count, the 6960P outperforms the 6980P by 75.8% in multi-core tests.

The Verdict

The data presents a clear picture. The Intel Xeon 6960P is the superior processor in 13 of 14 head-to-head benchmarks, with the only exception being extended instructions. Its 75.8% multi-core advantage, 95.5% single-thread advantage, and 644.4% physics advantage make it the better choice for nearly every workload in the recorded dataset.

The 6980P's larger core count does not translate into performance wins. Despite 56 additional cores, it cannot overcome the 6960P's higher base clock, superior per-core cache allocation, and more efficient frequency scaling. The 6980P's 10% edge in extended instructions is real but narrow, and it applies to a specialized workload segment.

For users selecting between these two parts, the choice depends on workload mix. The 6960P should be selected for rendering, physics simulation, single-threaded applications, data compression, encryption, and integer-heavy tasks. The 6980P is only preferable for environments that specifically leverage extended instruction sets and can tolerate significantly lower performance everywhere else.

The 6960P also offers the higher percentile ranking at 100 versus 99, a higher average benchmark score of 365194 versus 251516, and a lower launch MSRP of $9625 versus $12460. Given that the less expensive part wins nearly every benchmark, the 6960P is the data-supported choice for most deployments. The 6980P remains an option only for narrow, instruction-set-specific use cases where its 10% advantage in extended instructions outweighs the substantial losses in all other measured categories.
