Intel Core i9-11900H vs Intel Xeon D-1746TER Comparison

The Intel Xeon D-1746TER and Intel Core i9-11900H are both 10nm Intel parts, but they target entirely different corners of the market. The Xeon D-1746TER is an Ice Lake-D server/workstation chip with 10 cores and 20 threads, while the i9-11900H is a Tiger Lake-H mobile processor with 8 cores and 16 threads. In the head-to-head benchmark data, the i9-11900H wins every single one of the 17 recorded tests. However, the Xeon D-1746TER holds its own in overall standing, with an average benchmark score of 21635 compared to the i9-11900H’s 21367, and both sit at the 75th percentile of all CPUs. This creates an interesting dynamic: the mobile chip dominates in raw performance tests, but the server chip is built for stability, memory bandwidth, and platform features that the benchmark scores don't fully capture.

Where Each One Wins

The benchmark data is unambiguous: the Intel Core i9-11900H wins all 17 head-to-head tests. There is no test in the provided results where the Xeon D-1746TER comes out ahead. The i9-11900H’s wins span every category, from single-threaded Cinebench scores to multithreaded PassMark workloads. This makes the i9-11900H the clear choice for anyone prioritizing raw compute performance in the tested workloads, whether that be rendering, encryption, or floating-point math.

The Xeon D-1746TER’s strengths lie outside the benchmark suite. It supports ECC memory, which the i9-11900H does not. It uses a triple-channel memory bus with 64.0 GB/s of bandwidth compared to the i9-11900H’s dual-channel 51.2 GB/s. For a server or workstation environment where data integrity and memory throughput matter more than peak single-thread speed, the Xeon D-1746TER is the more appropriate part. Its market segment is listed as Server/Workstation, while the i9-11900H is a Mobile part. The Xeon D-1746TER is also still in Active production, whereas the i9-11900H is End-of-life.

In short, the i9-11900H wins where benchmarks are measured, but the Xeon D-1746TER wins where platform features and reliability are the priority. If you are building a dense, low-power server node, the Xeon D-1746TER’s feature set is what you are paying for. If you are building a high-performance laptop or compact mobile workstation, the i9-11900H’s benchmark dominance is what you want.

Architecture Differences

The two processors are built on different architectures within the same 10 nm process node. The Xeon D-1746TER uses the Ice Lake architecture, specifically the Ice Lake-D codename, which is designed for embedded and edge server workloads. The i9-11900H uses the Tiger Lake architecture, with the Tiger Lake-H codename, which is optimized for high-performance mobile computing. Both are manufactured by Intel, but they are distinct silicon designs.

The core counts differ: the Xeon D-1746TER has 10 cores and 20 threads, while the i9-11900H has 8 cores and 16 threads. The i9-11900H compensates with a significantly higher boost clock: 4.90 GHz versus the Xeon’s 3.10 GHz. The base clocks are closer, at 2.10 GHz for the i9-11900H and 2.00 GHz for the Xeon D-1746TER. The i9-11900H also has a larger shared L3 cache at 24 MB, compared to the Xeon’s 15 MB. Both share the same per-core L1 and L2 cache sizes: 80 KB and 1.25 MB per core, respectively.

The memory architecture diverges sharply. The Xeon D-1746TER supports triple-channel DDR4 memory with a peak bandwidth of 64.0 GB/s and ECC support. The i9-11900H supports dual-channel DDR4 with 51.2 GB/s bandwidth and no ECC. The Xeon D-1746TER has 16 PCIe Gen 4 lanes (CPU only), while the i9-11900H has 20 PCIe Gen 4 lanes. The i9-11900H also includes integrated graphics (UHD Graphics 750), whereas the Xeon D-1746TER has no integrated graphics. The Xeon’s die size is not listed, while the i9-11900H’s die is 190 mm².

The power envelopes are telling. The Xeon D-1746TER has a TDP of 67W, while the i9-11900H is rated at 35W. This is counterintuitive given the i9-11900H’s higher performance, but it reflects the different design goals: the Xeon is a server part that prioritizes sustained throughput and reliability, while the i9-11900H is a mobile part designed to hit high boost clocks in short bursts within a thermal budget. The Xeon D-1746TER is also the newer release, dated 2022-02-23, versus the i9-11900H’s 2021-05-10.

Head-to-Head Benchmarks

The i9-11900H’s dominance is consistent across every workload. In Cinebench R23 multicore, the i9-11900H scores 16772 against the Xeon D-1746TER’s 13311, a 20.6% advantage. The single-core gap is identical at 20.6%, with scores of 2367 versus 1879. This pattern repeats across all Cinebench versions: R15 multicore (1690 vs 1341, -20.7%), R15 single-core (238 vs 189, -20.6%), R20 multicore (7044 vs 5590, -20.6%), and R20 single-core (994 vs 789, -20.6%). The i9-11900H’s higher boost clock of 4.90 GHz is clearly the deciding factor in these latency-sensitive render tests.

The PassMark suite shows a wider spread of deltas. The largest single-score gap is in PassMark single-thread, where the i9-11900H scores 3102 against the Xeon’s 1785, a 42.5% difference. This is a massive margin that highlights the i9-11900H’s superior per-core performance. In integer math, the i9-11900H scores 72882 versus 54482, a 25.2% lead. Floating-point math shows a 24% gap (43094 vs 32772), and data encryption is 23.6% apart (12232 vs 9343). The smallest delta is in physics, where the i9-11900H leads by only 9.9% (953 vs 859).

Even in multithreaded workloads, where the Xeon D-1746TER has more cores, the i9-11900H wins. PassMark multithread scores are 20162 for the i9-11900H versus 15660 for the Xeon, a 22.3% gap. Data compression shows a 20% difference (239366 vs 191594), and random string sorting is 16.2% apart (28328 vs 23732). The Xeon’s 10 cores and 20 threads cannot overcome the i9-11900H’s higher clock speeds and larger L3 cache. The i9-11900H also wins in extended instructions (16123 vs 12620, -21.7%) and prime number finding (87 vs 68, -21.8%).

The Verdict

The data is clear: if you are choosing based solely on benchmark performance, the Intel Core i9-11900H is the superior CPU. It wins all 17 head-to-head tests, often by margins of 20% or more. Its 4.90 GHz boost clock and 24 MB L3 cache give it a decisive edge in both single-threaded and multithreaded workloads. The i9-11900H is the right pick for a high-performance mobile workstation or any application where raw compute speed is the priority.

The Xeon D-1746TER, however, is not without its reasons to exist. Its triple-channel memory bus with 64.0 GB/s bandwidth and ECC support make it the better choice for a server or workstation where data integrity and memory throughput are critical. Its 10 cores and 20 threads provide a solid foundation for heavily threaded server workloads, even if those workloads are not reflected in the benchmark suite provided. It also remains in Active production, while the i9-11900H is End-of-life.

For most users, the i9-11900H is the obvious winner. For a specific niche of server builders who need ECC memory, a triple-channel memory bus, and a 67W TDP in a BGA 2227 package, the Xeon D-1746TER is the targeted solution. The benchmark data says one thing, but the platform specifications tell a different story for a different audience.
