Intel Xeon D-2799 vs Intel Xeon Platinum 8180M Comparison

The Intel Xeon D-2799 and Intel Xeon Platinum 8180M are both server-class processors, yet they represent vastly different design philosophies from Intel. The D-2799 is a modern, power-efficient Ice Lake-D part built for dense, integrated systems, while the Platinum 8180M is a high-core-count Skylake-SP flagship from an earlier generation. Benchmark data from the Cinebench suite shows a clean sweep for the D-2799 across all six tests, despite the 8180M offering more cores and higher clock speeds. This analysis breaks down where each chip wins, the architectural reasons behind the results, and what the numbers mean for real-world workloads.

Where Each One Wins

The benchmark results are unambiguous: the Intel Xeon D-2799 wins every single head-to-head comparison in the Cinebench suite, taking all six tests. This includes both multi-core and single-core workloads, meaning the D-2799 is the superior choice for rendering, 3D modeling, and any task that scales with thread count, as well as for lightly-threaded applications that depend on per-core performance. The data shows no scenario in the tested benchmarks where the Platinum 8180M comes out ahead.

The Platinum 8180M, however, is not without its strengths in the broader context. It features a significantly higher core count (28 cores versus 20) and a higher boost clock (3.80 GHz versus 3.40 GHz), which suggests it could be competitive in highly parallel, memory-intensive server workloads outside of the Cinebench suite, particularly those that leverage its larger 38.5 MB shared L3 cache. Yet, within the provided Cinebench results, the D-2799’s architectural efficiency and faster memory bandwidth (102.4 GB/s) prove decisive, delivering a 2.4% to 2.5% advantage across every test. The D-2799 is the clear winner for anyone prioritizing raw Cinebench performance per socket, while the 8180M might be considered for legacy software that favors higher core counts over IPC (instructions per clock) gains.

Architecture Differences

The two processors are built on fundamentally different architectures and process nodes, which explains their performance characteristics. The Intel Xeon D-2799 uses the Ice Lake architecture (Ice Lake-D) fabricated on Intel’s 10 nm process, whereas the Platinum 8180M uses the older Skylake architecture (Skylake-SP) on a 14 nm node. This generation gap is critical: the 10 nm node allows for denser transistors and better power efficiency, which is reflected in the D-2799’s dramatically lower TDP of 129 W compared to the 8180M’s 205 W.

Core and cache configurations also differ significantly. The D-2799 packs 20 cores and 40 threads, with 80 KB of L1 and 1.25 MB of L2 per core, plus a 30 MB shared L3 cache. The 8180M offers more raw compute with 28 cores and 56 threads, but its per-core cache is smaller: 64 KB of L1 and 1 MB of L2 per core. Its L3 cache is larger in total (38.5 MB shared) but shared across more cores. The D-2799 also benefits from a newer memory interface, supporting quad-channel DDR4 with a stated memory bandwidth of 102.4 GB/s, while the 8180M’s memory bus and bandwidth are not specified in the data.

Connectivity and packaging also diverge. The D-2799 uses the Intel BGA 2579 socket, indicating a soldered, embedded-style design, and features PCIe Gen 4 with 32 lanes (CPU only). The 8180M uses the LGA-style Intel Socket 3647 and has no PCIe information listed, which suggests a more traditional upgradeable server platform. The D-2799 is listed as having an active production status with a release date in 2022, while the 8180M’s production status is null, and it was released much earlier in 2017. These differences highlight the D-2799 as a modern, integrated solution versus the 8180M as an older, high-core-count behemoth.

Head-to-Head Benchmarks

The Cinebench results show a consistent, narrow victory for the Intel Xeon D-2799 across every iteration and workload type. In Cinebench R15, the D-2799 scores 2895 in multi-core against the 8180M’s 2826, a 2.4% win. In single-core, the D-2799 scores 408 versus 398, a 2.5% advantage. This pattern repeats in Cinebench R20, where the D-2799 leads multi-core with 12063 points over 11776 (2.4% delta) and single-core with 1703 over 1662 (2.5% delta). The trend continues into Cinebench R23, with the D-2799 posting 28723 in multi-core versus 28040 (2.4% delta) and 4055 in single-core versus 3958 (2.5% delta).

The largest absolute gap is in Cinebench R23 multi-core, where the D-2799 leads by 683 points. The smallest absolute gap is in Cinebench R15 single-core, a 10-point difference. Notably, the deltaPct is remarkably stable: exactly 2.4% for all multi-core tests and 2.5% for all single-core tests. This consistency suggests the D-2799’s advantage is architectural—likely due to higher IPC from the Ice Lake design and faster memory bandwidth—rather than workload-specific. The 8180M’s higher core count (28 vs 20) is not enough to overcome the per-core efficiency of the D-2799, which wins despite having 8 fewer cores. In terms of average benchmark score, the D-2799 also leads with 8308 points versus 8110 for the 8180M, a difference of about 2.4% that mirrors the head-to-head results.
