Analysis: Intel Xeon 6730P vs Intel Xeon 6745P
The two 32-core Intel Xeon processors, the 6745P and 6730P, both belong to the Granite Rapids family and share the same socket, process node, and memory subsystem. The recorded benchmark data shows the 6745P winning 14 of the 16 head-to-head tests, while the 6730P takes two notable wins. This analysis walks through the benchmark results, the architectural differences, and the implications for different workloads.
Head-to-Head Benchmarks
The Cinebench results are uniformly in favor of the 6745P. In the R15 multicore test, the 6745P scores 7214 against the 6730P's 6349, a 13.6% difference. The single-core R15 test shows the same 13.6% delta, with 1018 versus 896. R20 repeats the pattern: the 6745P scores 30062 versus 26458 in multicore, and 4244 versus 3735 in single-core, again 13.6% apart. The R23 multicore test continues the trend with 71578 versus 62996, a 13.6% lead. These results indicate a consistent performance advantage across all Cinebench rendering workloads.
The PassMark suite shows a wider spread. In data compression, the 6745P scores 1352801 versus 1138470, a lead of 18.8%. Data encryption shows a 19.1% advantage, with 66665 against 55964. Extended instructions are 12.6% higher, at 108326 versus 96204. Floating point math is 17.9% higher, at 267438 versus 226838, while integer math is 15.9% higher at 336926 versus 290740. The multithread score is 13.6% higher at 84210 versus 74113, and the single-thread score is 15.2% higher at 3450 versus 2995. Random string sorting is 17.2% higher, at 133528 versus 113919.
The 6730P takes two wins. In the find prime numbers test, it edges out the 6745P by 0.7%, scoring 686 to 681. The more dramatic win is in the physics test, where it scores 8606 against 6144, a 28.6% advantage. That is the largest single delta in either direction, and it stands out as a striking outlier in an otherwise one-sided comparison.
Looking at the broader context, the 6745P sits at the 98th percentile of all CPUs in the database, with an average benchmark score of 154858. Its nearest rivals show it trailing slightly: the Intel Xeon 676X is 2.3% ahead, the AMD EPYC 9355P is 3.4% ahead, the AMD EPYC 7663 is 4.4% ahead, and the AMD EPYC 9375F is 4.7% ahead. The 6730P, at the 97th percentile, has an average score of 124756. It is 0.5% ahead of the AMD Ryzen Threadripper PRO 5975WX, 0.6% ahead of the AMD EPYC 7642, 1.6% behind the AMD EPYC 9354, and 3.6% ahead of the AMD EPYC 9384X. This means the 6730P sits in a competitive pack, while the 6745P is closer to the top of the overall distribution.
Architecture Differences
Both processors share the Granite Rapids architecture, the same 5 nm process, and the same dual-die design with a 2x 598 mm² die area. The socket is Intel Socket 4710 for both. The memory subsystem is identical: DDR5 with eight channels, a 409.6 GB/s bandwidth, and ECC support. The PCIe interface is also the same, with 88 Gen 5 lanes from the CPU. Neither has integrated graphics.
The key differences are clock speeds, TDP, and cache. The 6745P has a base clock of 3.10 GHz and a boost clock of 4.30 GHz, while the 6730P runs at 2.50 GHz base and 3.80 GHz boost. The 6745P has a TDP of 300W, the 6730P 250W. The shared L3 cache is 336 MB on the 6745P versus 288 MB on the 6730P. The L1 and L2 caches are identical per core, at 112 KB and 2 MB respectively. The 6745P has a launch MSRP of $5250, while the 6730P has a launch MSRP of $3726.
The Verdict
The data clearly points to the 6745P as the stronger overall performer. It is 13.6% faster across every Cinebench test, which covers both multicore and single-core rendering workloads. Its PassMark leads range from 12.6% in extended instructions to 19.1% in data encryption. The average benchmark score of 154858 versus 124756 reinforces this dominance. For compute-heavy server tasks, such as video rendering, data compression, and mathematical workloads, the 6745P is the better choice.
The 6730P, however, is not without its strengths. Its 28.6% lead in physics is a significant outlier, and it also wins the prime number finding test by 0.7%. This suggests that the 6730P has a specific niche in physics-based simulations and number-theoretic computations. Additionally, its lower TDP of 250W makes it a more power-efficient option for data centers where thermal limits are a concern. For these specific workloads, the 6730P is the appropriate pick.

Where Each One Wins
The 6745P is the winner for all Cinebench render tests, all PassMark math and compression tests, and the multithread and single-thread scores. Its 19.1% lead in data encryption and 18.8% lead in data compression make it well-suited for security and storage workloads. The 12.6% advantage in extended instructions helps with instruction-heavy code. For general server workloads, the 6745P is the dominant choice.
The 6730P's two wins are physics and prime numbers. The 28.6% physics lead is a major outlier, suggesting that any workload involving rigid body dynamics, particle systems, or similar simulations would favor the 6730P. The prime number finding test is a small but real edge. The 6730P also has the advantage of a lower TDP, making it a better fit for power-constrained environments.
