Intel Xeon 6732P vs Intel Xeon w7-3565X Comparison

The Verdict

The data paints a remarkably one-sided picture. The Intel Xeon 6732P wins 15 of the 17 recorded head-to-head benchmarks, while the Intel Xeon w7-3565X takes only 2. The average benchmark score for the 6732P is 143444, placing it at the 98th percentile of all CPUs, while the w7-3565X averages 118307 and sits at the 97th percentile. That gap in average score, roughly 21% in favor of the 6732P, is the first sign that these two 32-core processors are not in the same performance class despite their matching core counts.

The w7-3565X does hold one clear advantage: single-threaded PassMark performance. It scores 3407 in passmark_single_thread versus 2506 for the 6732P, a 26.4% lead. This is the only meaningful territory where the older Sapphire Rapids chip wins. Anyone whose workload is dominated by lightly threaded applications, where a single core's maximum speed matters more than the aggregate, should look at the w7-3565X.

For everything else, the 6732P is the answer. Its most dramatic win comes in passmark_physics, where it scores 8109 against 4254, a 90.6% advantage. It also crushes the w7-3565X in passmark_find_prime_numbers by 57.8%, and leads by roughly 20% in floating-point math, integer math, data compression, and random string sorting. The Cinebench suite shows a consistent 6% edge across R15, R20, and R23 in both single and multi-core tests.

The verdict is straightforward. The 6732P is the stronger all-around performer for multi-threaded, data-heavy, and compute-intensive server workloads. The w7-3565X is the pick only for single-threaded tasks where its higher boost clock and unlocked multiplier matter more than the architectural efficiency of the newer part.

Architecture Differences

The two processors come from different Intel design generations. The 6732P uses the Granite Rapids architecture on a 5 nm process node, while the w7-3565X is built on Sapphire Rapids using a 10 nm process. The 6732P is part of the Xeon 6 (Granite Rapids-SP) generation, and the w7-3565X belongs to the Xeon W (Sapphire Rapids) generation.

The cache layouts reveal substantial differences. The 6732P provides 112 KB of L1 per core and a massive 144 MB of shared L3 cache. The w7-3565X offers only 80 KB of L1 per core and 82.5 MB of L3. Both have 2 MB of L2 per core. The 6732P's L3 advantage, nearly 75% more shared cache, helps explain its dominance in data-heavy PassMark tests like data compression and random string sorting.

Memory bandwidth also favors the newer part. The 6732P delivers 409.6 GB/s over an eight-channel DDR5 bus, while the w7-3565X manages 307.2 GB/s on the same eight-channel DDR5 configuration. That is a 33% bandwidth advantage for the 6732P, a significant margin for workloads that saturate memory.

The physical packages differ as well. The 6732P uses Intel Socket 4710, while the w7-3565X uses Intel Socket 4677. The w7-3565X has a reported die size of 4x 477 mm², a detail not recorded for the 6732P. PCIe lane counts also differ: the 6732P offers Gen 5 with 136 lanes, while the w7-3565X offers Gen 5 with 112 lanes.

The w7-3565X has an unlocked multiplier, meaning it supports overclocking. The 6732P does not. The base and boost clocks tell an interesting story: the 6732P starts at 3.80 GHz and boosts to 4.10 GHz, while the w7-3565X starts much lower at 2.50 GHz but boosts much higher to 4.80 GHz. Despite the w7-3565X's higher boost ceiling, the 6732P still wins every Cinebench single-core test, suggesting that the Granite Rapids architecture extracts more performance per GHz in those workloads.

FAQ

Q: Which processor has more cores?

Head-to-Head Benchmarks

The 6732P wins every Cinebench test. In R15 multicore, it scores 6412 versus 6052, a 5.9% lead. R15 single-core sees 905 versus 854, a 6% lead. R20 multicore is 26720 versus 25218, a 6% lead. R20 single-core is 3772 versus 3560, also 6%. R23 multicore is 63621 versus 60045, a 6% lead. R23 single-core is 8981 versus 8477, a 5.9% lead. These are consistent margins, suggesting a uniform architectural advantage across rendering and general compute workloads.

The PassMark suite amplifies the 6732P's dominance in specific areas. The most striking result is passmark_physics: 8109 versus 4254, a 90.6% lead. This is by far the largest delta in the entire comparison. The 6732P also wins passmark_find_prime_numbers by 57.8% (628 versus 398), suggesting a major advantage in integer-heavy, branch-heavy workloads.

Data-oriented tests show the 6732P ahead by roughly 20% across the board. Data compression scores 1339480 versus 1075602, a 24.5% lead. Data encryption scores 63848 versus 54676, a 16.8% lead. Extended instructions score 106697 versus 85856, a 24.3% lead. Floating-point math scores 261703 versus 218720, a 19.7% lead. Integer math scores 334340 versus 279202, also 19.7%. Random string sorting scores 133467 versus 110848, a 20.4% lead.

The passmark_multithread test gives the 6732P a 6% win (74849 versus 70642), matching the Cinebench multicore margins.

The w7-3565X's only wins are the two identical single-thread PassMark entries. Both passmark_single_thread and passmark_singlethread record 3407 for the w7-3565X versus 2506 for the 6732P, a 26.4% lead for the older chip. This is the one benchmark category where the w7-3565X's 4.80 GHz boost clock appears to overcome the 6732P's architectural advantages.

The average benchmark scores confirm the overall picture. The 6732P averages 143444, which is 0.2% behind the AMD Ryzen 9 PRO 9965X3D, 0.2% ahead of the Intel Xeon 674X, 0.6% behind the Intel Xeon w9-3575X, and 1% behind the AMD EPYC 7643P. The w7-3565X averages 118307, which is 1.6% ahead of the AMD EPYC 9255, 1.8% behind the AMD EPYC 9384X, 1.9% ahead of the Intel Xeon 658X, and 2.7% ahead of the Intel Xeon 6527P.

Where Each One Wins

The 6732P wins in every multi-threaded and data-intensive category. Its 144 MB L3 cache and 409.6 GB/s memory bandwidth make it the stronger choice for compression, encryption, sorting, and other memory-bound operations. The 24.5% lead in data compression and 20.4% lead in random string sorting point to workloads that benefit from large caches and fast memory access. The 90.6% lead in physics and 57.8% lead in prime number finding suggest a decisive edge in scientific computing, simulation, and other integer-heavy tasks.

The w7-3565X wins only in the PassMark single-thread test, with a 26.4% margin. This makes it the better option for software that cannot use many cores and relies heavily on a single thread's peak speed. Its 4.80 GHz boost clock and unlocked multiplier give it headroom for overclocking, which could extend that single-thread advantage further. However, even in Cinebench single-core tests, the 6732P manages to win by 6%, so the w7-3565X's single-thread superiority is specific to the PassMark methodology rather than universal.

For server and workstation deployments running parallel workloads, database operations, rendering, or scientific simulations, the 6732P is the clear choice. The data shows it leading by double digits in most PassMark sub-tests and by 6% across all Cinebench variants. For a workstation that primarily runs older or lightly threaded applications, the w7-3565X offers a compelling single-thread advantage, though its lower average benchmark score and smaller cache make it less versatile for mixed workloads.
