Intel Xeon 6710E vs Intel Xeon 6732P Comparison

# Intel Xeon 6732P vs Intel Xeon 6710E

The Intel Xeon 6732P and Intel Xeon 6710E are two very different server processors sharing the same Intel Socket 4710 platform, yet they target opposite ends of the workload spectrum. The 6732P is a Granite Rapids part with 32 high-frequency performance cores, while the 6710E is a Sierra Forest chip with 64 efficiency-oriented cores. Benchmark data shows the 6732P wins 15 of 17 head-to-head tests, but the 6710E takes two notable victories in encryption and string sorting. The 6732P sits at the 98th percentile of all CPUs with an average benchmark score of 143444, while the 6710E ranks at the 97th percentile with a 129930 average. Despite having half the cores, the 6732P delivers consistently higher throughput in most measured workloads, though the 6710E's lower power envelope and different architectural priorities tell a more nuanced story.

Where Each One Wins

The Intel Xeon 6732P dominates compute-heavy and single-thread-sensitive workloads. Its wins span every Cinebench test (R15, R20, R23) in both single-core and multi-core variants, with a uniform 21.2% advantage across all six. This consistency points to a fundamental clock-speed and per-core performance edge rather than workload-specific optimization. The 6732P also excels in extended instruction workloads, scoring 106697 versus 59625—a massive 78.9% lead that indicates superior SIMD and encryption instruction handling. Physics simulation favors the 6732P even more dramatically, with an 8109 score against the 6710E's 5000, a 62.2% gap. Prime number finding also goes to the 6732P by 39.2%, and floating-point math by 19%.

The Intel Xeon 6710E wins where its high core count and different cache topology pay off. Data encryption is its strongest showing, scoring 81850 against the 6732P's 63848, a 22% advantage. Random string sorting also favors the 6710E, with 151491 versus 133467, an 11.9% edge. These two wins suggest the 6710E handles memory-bound, parallelizable data manipulation tasks better, likely due to its 64 cores and 4 MB L2 cache per module. However, these are the exceptions. The 6710E's 97th percentile ranking versus the 6732P's 98th percentile confirms the overall performance hierarchy, even if the 6710E offers a more compelling core-per-watt proposition.

Architecture Differences

The two processors come from distinct Intel architectures. The 6732P uses Granite Rapids, part of the Xeon 6 (Granite Rapids-SP) generation, while the 6710E uses Sierra Forest from the Xeon 6 (Sierra Forest-SP) generation. Both are built on Intel's 5 nm process, but the design philosophies diverge sharply. The 6732P packs 32 cores with 64 threads, while the 6710E has 64 cores but also 64 threads—meaning the 6710E's cores lack simultaneous multithreading, effectively giving it one thread per core. This explains why the 6710E's higher core count doesn't translate into multi-threaded dominance.

Clock speeds tell a clear story. The 6732P runs at 3.80 GHz base and 4.10 GHz boost, while the 6710E is significantly slower at 2.40 GHz base and 3.20 GHz boost. The 6732P's higher clocks are the primary driver of its single-thread and lightly-threaded performance wins. Power consumption differs dramatically: the 6732P has a 350 W TDP, while the 6710E draws only 205 W—a 145 W difference that favors the efficiency-oriented 6710E for dense deployments.

Cache layouts are also distinct. The 6732P provides 112 KB L1 per core, 2 MB L2 per core, and 144 MB shared L3. The 6710E offers 96 KB L1 per core, 4 MB L2 per module, and 96 MB shared L3. The 6710E's larger per-module L2 compensates for its smaller L3, which may explain its string sorting and encryption wins. Memory bandwidth favors the 6732P at 409.6 GB/s versus 358.4 GB/s, both using DDR5 across eight channels. PCIe lane counts differ substantially: the 6732P provides 136 Gen 5 lanes (CPU only), while the 6710E offers 88 lanes. The 6732P also has a larger die footprint rationale, though the 6710E's die size is listed at 578 mm² while the 6732P's is not specified.

Head-to-Head Benchmarks

The Cinebench results are remarkably uniform. Across R15, R20, and R23, the 6732P wins both single-core and multi-core by exactly 21.2% each time. For example, in Cinebench R23 multi-core, the 6732P scores 63621 against the 6710E's 52508. Single-core R23 shows 8981 versus 7413. This consistent margin suggests the 6732P's clock advantage translates linearly across rendering workloads, regardless of thread count.

PassMark tests reveal a more varied picture. The 6732P's biggest victory is in extended instructions, where it scores 106697 versus 59625, a 78.9% gap. This is the largest delta in the entire benchmark suite and highlights the 6732P's superior execution of complex instruction sets. Physics simulation shows the second-largest gap at 62.2% (8109 vs 5000), followed by prime number finding at 39.2% (628 vs 451). Single-thread performance favors the 6732P by 31.2% (2506 vs 1910), and floating-point math by 19% (261703 vs 219926). Integer math is closer, with the 6732P ahead by 10.4% (334340 vs 302954), and data compression shows an 8.8% edge (1339480 vs 1230786).

The 6710E's wins are notable for their specificity. Data encryption shows a 22% advantage (81850 vs 63848), and random string sorting an 11.9% edge (151491 vs 133467). These are memory-latency-sensitive and parallel-scaling workloads where the 6710E's 64 cores and per-module L2 cache configuration provide an advantage. However, even in multi-threaded PassMark tests, the 6732P wins the multithread benchmark by 21.2% (74849 vs 61775), indicating that the 6710E's core count cannot overcome its clock deficit in most scenarios.

The Verdict

The data clearly favors the Intel Xeon 6732P for raw performance. It wins 15 of 17 head-to-head benchmarks, including every rendering, math, physics, and single-thread test. Its 21.2% uniform lead in Cinebench workloads and 78.9% advantage in extended instructions make it the obvious choice for compute-intensive applications, virtualization, and workloads that benefit from high clock speeds and strong per-core performance. The 6732P's 98th percentile ranking versus the 6710E's 97th percentile reflects this superiority in aggregate benchmark scores.

The Intel Xeon 6710E is not without merit, but its appeal is narrower. Its 22% encryption win and 11.9% string sorting advantage indicate suitability for specific data-processing tasks, and its 205 W TDP versus the 6732P's 350 W makes it far more power-efficient. For deployments where power density is critical and workloads align with its strengths—encryption, sorting, and parallel data manipulation—the 6710E is the rational pick. Its 64 cores also provide higher core density for heavily threaded workloads that scale linearly, even if benchmark results show the 6732P still wins most multithreaded tests.

The verdict depends on priorities. If maximum performance per socket matters, the 6732P is the clear winner. If power efficiency and specific data-plane workloads matter more, the 6710E justifies its existence. The 6732P also offers more PCIe lanes (136 vs 88) and higher memory bandwidth (409.6 vs 358.4 GB/s), reinforcing its position as the more capable general-purpose server processor. The 6710E's launch MSRP is $2749, while the 6732P's is $5295, but the 6732P's benchmark dominance suggests the price gap reflects genuine performance differences. For most server workloads, the 6732P is the data-backed recommendation.
