Intel Xeon 6730P vs Intel Xeon 6732P Comparison

# Where Each One Wins

The benchmark data splits these two 32-core Granite Rapids processors into distinct use-case profiles. The Intel Xeon 6732P wins 13 of 17 head-to-head tests, while the Intel Xeon 6730P takes 4. But the margins tell a more interesting story than the raw win count.

The 6732P dominates in throughput-oriented workloads. Its largest victories come in data compression (17.7% ahead), random string sorting (17.2% ahead), floating-point math (15.4% ahead), and integer math (15% ahead). These are classic server workloads: database compression, sorting algorithms, scientific computing, and general number crunching. The 6732P also leads in data encryption by 14.1% and extended instructions by 10.9%, covering cryptographic workloads and SIMD-heavy applications.

The 6730P, meanwhile, wins in three specific areas: single-threaded PassMark tests (16.3% ahead), prime number finding (8.5% ahead), and physics simulation (5.8% ahead). The PassMark single-thread score of 2995 versus 2506 is notable, but the other two wins are smaller and more niche. Prime number finding and physics simulation often reward memory latency and cache behavior differently than pure throughput.

In the Cinebench suite, the 6732P wins all six tests, but by just 1% each time. That includes both single-core and multi-core variants of R15, R20, and R23. The PassMark multithread test also goes to the 6732P by 1%. This pattern suggests that for purely CPU-bound rendering and multi-threaded compute, the two chips are nearly interchangeable.

The verdict from the win breakdown: the 6732P is the general-purpose compute leader, particularly for data-heavy and math-heavy workloads. The 6730P is the better choice for single-thread responsiveness and specific latency-sensitive tasks, but its wins are concentrated in fewer tests.

# Architecture Differences

Both processors share the same fundamental design: Granite Rapids architecture, 5 nm process node, Intel Socket 4710, and 32 cores with 64 threads. Both use DDR5 memory with an eight-channel bus and 409.6 GB/s bandwidth. ECC memory support is present on both. Neither has integrated graphics.

The first major difference is clock speed. The 6732P runs at a base clock of 3.80 GHz and boosts to 4.10 GHz. The 6730P sits at 2.50 GHz base and 3.80 GHz boost. That 1.30 GHz base clock gap explains most of the 6732P's throughput advantage in multi-threaded tests, as all 32 cores can sustain higher frequencies under load.

Thermal design power differs substantially: the 6732P is rated at 350 W, while the 6730P draws 250 W. This is directly tied to the clock speed difference and has implications for cooling requirements and power delivery.

Cache configurations are not identical. Both have 112 KB L1 per core and 2 MB L2 per core. However, the shared L3 cache differs significantly: the 6732P has 144 MB shared, while the 6730P has 288 MB shared. The 6730P's larger L3 cache is double that of the 6732P and may explain its wins in prime number finding and physics simulation, which can benefit from larger working sets residing in cache.

PCIe lane counts also differ. The 6732P provides Gen 5 with 136 lanes (CPU only), while the 6730P provides Gen 5 with 88 lanes (CPU only). For systems needing many NVMe drives, GPUs, or high-speed networking cards, the 6732P offers more expansion headroom.

The die size is only recorded for the 6730P: 2x 598 mm². The 6732P entry leaves this field unspecified in the database.

Release dates show the 6730P launched on 2025-02-23, while the 6732P followed on 2025-05-21. Both are listed as Active in production status. The part numbers differ: SRVP2 for the 6732P and SRV5R for the 6730P.

# The Verdict

The data points to different buyers for each chip.

Choose the Intel Xeon 6732P when you need maximum multi-threaded throughput in data-heavy workloads. It leads by double digits in data compression (17.7%), encryption (14.1%), floating-point math (15.4%), integer math (15%), and random string sorting (17.2%). The higher base clock of 3.80 GHz versus 2.50 GHz gives it a sustained advantage across all cores. Its 136 PCIe lanes also support more peripherals than the 88 lanes on the 6730P. The 350 W TDP is the price for that performance, but if your infrastructure can handle the power and cooling, the 6732P is the stronger compute engine.

Choose the Intel Xeon 6730P when single-thread performance or cache capacity matters more than raw throughput. Its PassMark single-thread score of 2995 is 16.3% above the 6732P's 2506. Its 288 MB L3 cache is double the 6732P's 144 MB, which likely contributes to its wins in prime number finding (8.5% ahead) and physics simulation (5.8% ahead). The 250 W TDP is 100 W lower, simplifying cooling design. The earlier launch date and lower power envelope may appeal to deployments where efficiency and latency per thread are priorities.

For Cinebench rendering workloads, the two are effectively tied, with the 6732P ahead by 1% across all six tests. If your primary workload is rendering, either chip delivers near-identical results, and other factors like power or PCIe lanes should drive the decision.

The average benchmark scores place the 6732P at 143444 and the 6730P at 124756. The 6732P sits at the 98th percentile of all CPUs, while the 6730P sits at the 97th. Both are elite performers, but the 6732P is the more complete package for compute-intensive applications.

# Head-to-Head Benchmarks

The largest margin in the entire comparison is data compression. The 6732P scores 1339480 against 1138470 for the 6730P, a 17.7% lead. This is a substantial gap for a workload that appears frequently in database and file-server environments. Random string sorting follows closely at 17.2% (133467 versus 113919), indicating that the 6732P handles sorting algorithms more efficiently.

Floating-point math shows a 15.4% advantage (261703 versus 226838), and integer math shows 15% (334340 versus 290740). These results confirm that the 6732P's higher clock speeds translate directly into arithmetic throughput. Data encryption trails slightly at 14.1% (63848 versus 55964), still a meaningful edge for secure communications and storage encryption workloads. Extended instructions round out the double-digit wins at 10.9% (106697 versus 96204), covering AVX and similar instruction set extensions.

The Cinebench results are remarkably consistent: all six tests show exactly a 1% delta in favor of the 6732P. R15 multi-core is 6412 versus 6349, R15 single-core is 905 versus 896, R20 multi-core is 26720 versus 26458, R20 single-core is 3772 versus 3735, R23 multi-core is 63621 versus 62996, and R23 single-core is 8981 versus 8893. The PassMark multithread test also lands at 1% (74849 versus 74113). This uniformity suggests that Cinebench workloads scale almost perfectly with clock speed, and the 6732P's higher frequencies provide a small but consistent edge.

The 6730P's largest win is PassMark single-thread, where it scores 2995 against 2506, a 16.3% advantage. This is the reverse of the clock speed trend, as the 6730P has a lower boost clock. The win likely stems from the larger 288 MB L3 cache improving single-thread memory access patterns. Find prime numbers goes to the 6730P by 8.5% (686 versus 628), and physics by 5.8% (8606 versus 8109). Both are respectable margins but represent narrower slices of the overall benchmark picture.
