Intel Xeon 6710E vs Intel Xeon 6745P Comparison

Head-to-Head Benchmarks

The benchmark data paints a clear picture of two very different server processors. The Intel Xeon 6745P wins 14 of 16 head-to-head comparisons, and in several tests the margin is dramatic. The most striking result is in extended instructions, where the 6745P scores 108326 against the 6710E's 59625, a 81.7% advantage. That is not a small edge; it is a near-doubling of throughput in workloads that rely on AVX-512 and other wide vector operations.

Single-thread performance tells a similar story. In PassMark single-thread testing, the 6745P scores 3450 versus 1910 for the 6710E, a 80.6% gap. Cinebench R15 single-core shows the same pattern: 1018 for the 6745P versus 747 for the 6710E, a 36.3% lead. The 6745P's boost clock of 4.30 GHz compared to 3.20 GHz on the 6710E explains much of this, but the architectural differences matter just as much, which we will cover in the next section.

Multi-threaded workloads also favor the 6745P despite the 6710E having twice as many cores. In Cinebench R23 multi-core, the 6745P scores 71578 versus 52508, a 36.3% margin. Cinebench R20 multi-core shows 30062 versus 22053, again 36.3%. PassMark multi-thread follows the same trend: 84210 versus 61775, a 36.3% delta. The consistency of that 36.3% figure across all three Cinebench versions and PassMark multi-thread is notable. It suggests the 6745P's per-core efficiency advantage is large enough to overcome the 6710E's core count advantage in these heavily threaded render workloads.

The 6710E does take two wins. Data encryption is one, scoring 81850 versus 66665, an 18.6% advantage for the 6710E. This is likely due to the higher core count and the specific encryption instruction throughput on the Sierra Forest architecture. Random string sorting is the other win: 151491 versus 133528, an 11.9% lead. These are real wins, and they point to workloads where more physical cores matter more than raw clock speed or vector width.

Other notable wins for the 6745P include floating-point math at 267438 versus 219926 (21.6% ahead), integer math at 336926 versus 302954 (11.2% ahead), and physics at 6144 versus 5000 (22.9% ahead). Prime number finding shows a 51% advantage (681 versus 451), and data compression is 9.9% ahead (1352801 versus 1230786).

Looking at the overall averages, the 6745P sits at a 98th percentile of all CPUs with an average benchmark score of 154858. The 6710E is at the 97th percentile with 129930. The nearest rival data for the 6745P shows it within 2.3% of the Intel Xeon 676X and 3.4% of the AMD EPYC 9355P. The 6710E sits 2.5% ahead of the AMD EPYC 9354 and 4.1% ahead of the Intel Xeon 6730P. Both are top-tier server chips, but the 6745P is clearly the stronger performer in most measured categories.

Architecture Differences

The two CPUs come from different Intel families, and that explains nearly everything about their benchmark behavior. The 6745P is built on Granite Rapids, while the 6710E uses Sierra Forest. Both are manufactured on Intel's 5 nm process, but the core designs diverge significantly.

The 6745P has 32 cores and 64 threads. The 6710E has 64 cores but also 64 threads, meaning it lacks simultaneous multithreading. This is a fundamental design choice: Sierra Forest prioritizes core density and power efficiency over per-thread performance. The 6745P, with its Granite Rapids cores, is designed for maximum single-thread and vector throughput.

Clock speeds reflect this. The 6745P runs at 3.10 GHz base and 4.30 GHz boost. The 6710E runs at 2.40 GHz base and 3.20 GHz boost. That 1.10 GHz boost clock difference is substantial and directly shows up in the 80.6% single-thread gap.

Cache layouts are also very different. The 6745P has 112 KB of L1 per core, 2 MB of L2 per core, and a massive 336 MB of shared L3 cache. The 6710E has 96 KB of L1 per core, 4 MB of L2 per module, and only 96 MB of shared L3. The 6745P's L3 cache is 3.5 times larger, which helps with large working sets and data-heavy workloads. The 6710E's L2 is organized per module rather than per core, reflecting its different core topology.

Physical die size differs too. The 6745P uses a dual-die design totaling 2x 598 mm², while the 6710E uses a single 578 mm² die. The 6745P's dual-die approach allows for more cache and higher clock speeds, but it also drives up power consumption. The 6710E's single die is more efficient in that regard.

Power envelopes are a major differentiator. The 6745P has a 300 W TDP, while the 6710E is rated at 205 W. That 95 W difference is significant for server power and cooling planning. The 6710E delivers 64 cores within a lower power budget, which is exactly what a high-density cloud or scale-out workload would want.

Memory bandwidth also differs. Both support DDR5 with eight-channel memory, but the 6745P achieves 409.6 GB/s versus 358.4 GB/s for the 6710E. That 51.2 GB/s difference matters for memory-bound workloads like database analytics or large in-memory processing.

Both CPUs share the same socket (Intel Socket 4710), same PCIe Gen 5 with 88 lanes, and both support ECC memory. Neither has integrated graphics. Release dates are different: the 6710E launched on 2024-06-02, while the 6745P followed on 2025-02-23. The launch MSRP for the 6745P is $5250, and for the 6710E it is $2749.

Where Each One Wins

The 6745P wins in any workload that rewards high clock speeds, wide vector instructions, or large cache. That includes single-threaded database queries, virtualization hosts with latency-sensitive workloads, scientific computing with AVX-512, financial modeling, and any application where a single core's performance is the bottleneck. The 81.7% lead in extended instructions is the clearest signal: if your code uses heavy SIMD, the 6745P is the only rational choice. The 36.3% wins across all Cinebench versions mean render farms and media encoding also favor the 6745P.

The 6710E wins in specific scenarios. Data encryption, where it leads by 18.6%, and random string sorting, where it leads by 11.9%, both benefit from having more physical cores even at lower clocks. If your workload is massively parallel with minimal per-thread complexity, the 6710E's 64 cores can outpace the 6745P's 32 faster cores. This is typical of cloud-scale web serving, container orchestration, and certain data transformation pipelines.

The 6710E also wins on power efficiency. At 205 W TDP versus 300 W, it delivers 64 cores at two-thirds the power draw. For a server rack with density requirements, that translates to more cores per watt and lower cooling costs. The 6745P compensates with higher performance per core, but it costs more to run.

FAQ

Q: Which CPU has better single-thread performance?

A: The 6745P is dramatically ahead. PassMark single-thread shows 3450 versus 1910, an 80.6% advantage. Cinebench R15 single-core shows 1018 versus 747, a 36.3% lead.

Q: Do both CPUs support ECC memory and PCIe Gen 5?

A: Yes. Both support ECC memory and both have PCIe Gen 5 with 88 lanes (CPU only).

Q: Which CPU has more L3 cache?

A: The 6745P has 336 MB shared L3, while the 6710E has 96 MB shared L3. That is a 3.5x difference.

The Verdict

The data is unambiguous for compute-heavy workloads. The Intel Xeon 6745P outperforms the Intel Xeon 6710E in 14 of 16 benchmark categories, with margins ranging from 9.9% to 81.7%. If your priority is raw throughput, especially for single-threaded or vector-heavy applications, the 6745P is the pick. Its 98th percentile standing against all CPUs, combined with an average score of 154858, places it among the fastest server processors available.

The 6710E is the right choice when core density and power efficiency matter more than per-core speed. Its 64 cores at 205 W TDP make it an excellent fit for high-density cloud environments, container hosts, and encryption-heavy workloads. The 97th percentile ranking and an average score of 129930 confirm it is no slouch, but it is a different kind of processor. The 6710E wins by doing more with less power, not by being faster.

For most general-purpose server deployments, the 6745P's benchmark dominance should sway the decision. The only reason to choose the 6710E is if your specific workload matches its two wins (encryption, string sorting) or if power and cooling constraints make the 205 W TDP mandatory. Otherwise, the 6745P delivers more performance across a wider range of applications.
