Intel Core i7-10700K vs Intel Xeon D-1746TER Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear and consistent picture: the Intel Core i7-10700K dominates the Intel Xeon D-1746TER in the vast majority of recorded tests. Out of 17 head-to-head comparisons, the Core i7-10700K claims 15 wins, while the Xeon D-1746TER manages only 2. The margins, however, vary dramatically depending on the workload type, and the Xeon's victories in specific security and prime-number tasks are notable.

The most lopsided results come from single-threaded performance. In the PassMark single-thread test, the Core i7-10700K scores 3043 against the Xeon's 1785, a commanding 70.5% advantage. This is the largest delta recorded between the two processors. The Cinebench single-core tests tell a similar story, though with narrower margins: the i7-10700K leads by 18% in Cinebench R15 (223 vs 189) and by 18.1% in Cinebench R23 (2220 vs 1879). These results reflect the desktop chip's high boost clock, which allows it to pull far ahead in lightly threaded applications.

Multi-threaded rendering workloads also favor the Core i7-10700K, but with surprisingly consistent margins. Across all three Cinebench versions (R15, R20, and R23), the i7-10700K wins by exactly 18.2% in multicore tests. The scores are 1585 vs 1341 in R15, 6605 vs 5590 in R20, and 15727 vs 13311 in R23. This uniformity suggests a stable architectural advantage rather than a workload-specific quirk. In PassMark multithread, the i7-10700K again leads, scoring 18609 versus 15660, a difference of 18.8%.

The i7-10700K's lead expands significantly in integer-heavy and floating-point workloads. PassMark integer math shows the desktop chip ahead by 22.3% (66642 vs 54482), while floating-point math favors it by 26% (41306 vs 32772). The gap grows even larger in extended instruction sets, where the i7-10700K scores 19387 against the Xeon's 12620, a 53.6% advantage. Data compression and random string sorting follow suit, with the i7-10700K winning by 54.2% (295418 vs 191594) and 54.4% (36633 vs 23732), respectively. These are substantial margins that point to the Core chip's superior per-core throughput in algorithmic tasks.

The Xeon D-1746TER's two wins are worth examining closely. In PassMark data encryption, the Xeon scores 9343 against the i7-10700K's 6468, a 30.8% advantage. This is the inverse of the pattern seen elsewhere, and it suggests that the Xeon's architecture includes capabilities that accelerate cryptographic operations. The Xeon also wins in PassMark find prime numbers, scoring 68 versus 55, a 19.1% lead. These victories, while narrow in the case of prime-number finding, are consistent with a server-oriented design that prioritizes certain instruction paths.

In the physics test, the i7-10700K wins by a modest 8.6% (933 vs 859), the smallest margin of its victories. This indicates that the two processors are more evenly matched in this particular workload, though the Core chip still comes out ahead. Overall, the benchmark database shows a processor that wins most tests by double digits, with only encryption and prime-number detection going the other way.

Architecture Differences

The two processors come from different Intel lineages and target entirely different market segments. The Core i7-10700K belongs to the Core 10th Gen family, built on the Comet Lake architecture and manufactured on a 14 nm process at Intel's foundry. It is a desktop part with 8 cores and 16 threads, a base clock of 3.80 GHz, and a boost clock of 5.10 GHz. The Xeon D-1746TER, by contrast, uses the Ice Lake-D architecture (codename Ice Lake-D) on a 10 nm process, also from Intel, and is aimed at the server and workstation segment. It offers 10 cores and 20 threads, but its clock speeds are much lower: a base clock of 2.00 GHz and a boost clock of 3.10 GHz.

Cache hierarchies differ as well. The i7-10700K has 64 KB of L1 cache per core, 256 KB of L2 per core, and 16 MB of shared L3 cache. The Xeon D-1746TER provides 80 KB of L1 per core, a much larger 1.25 MB of L2 per core, and 15 MB of shared L3. Despite having one fewer core, the Xeon's larger L2 cache per core could benefit certain workloads, though the benchmark data does not show a consistent advantage from this configuration. The i7-10700K's higher L3 total and higher clocks appear to matter more in most tests.

Memory support is another differentiator. Both processors support DDR4, but the i7-10700K uses a dual-channel memory bus with a bandwidth of 46.9 GB/s, while the Xeon D-1746TER uses a triple-channel bus with a higher bandwidth of 64.0 GB/s. The Xeon also supports ECC memory, a critical feature for server reliability, whereas the i7-10700K does not. PCIe connectivity also differs: the i7-10700K offers Gen 3 with 16 lanes (CPU only), while the Xeon provides Gen 4 with 16 lanes (CPU only), doubling the potential I/O bandwidth.

The i7-10700K includes integrated UHD Graphics 630, making it a self-contained solution for systems without a discrete GPU. The Xeon D-1746TER has no integrated graphics, which is typical for server processors that rely on dedicated management or compute GPUs. The i7-10700K has an unlocked multiplier, allowing overclocking, while the Xeon is locked. The i7-10700K uses the Intel Socket 1200, while the Xeon uses Intel BGA 2227, a soldered format common in embedded and server boards. The Xeon's TDP is 67 watts, considerably lower than the i7-10700K's 125 watts, reflecting its efficiency focus.

The release dates are separated by nearly two years: the i7-10700K launched on April 29, 2020, while the Xeon D-1746TER arrived on February 23, 2022. Both are listed as active in production. The Xeon carries a launch MSRP of $1069, while no launch MSRP is recorded for the i7-10700K in the database.

Where Each One Wins

Based on the recorded benchmark results, the Intel Core i7-10700K is the clear choice for workloads that depend on raw single-thread speed and general-purpose compute. Its 70.5% lead in PassMark single-thread scoring makes it well suited for applications like desktop responsiveness, gaming, and lightly threaded productivity tools. The consistent 18.2% advantage across all Cinebench multicore versions also makes it a strong option for rendering tasks, where higher clock speeds translate directly into faster completion times. Its wins in integer math (22.3%), floating-point math (26%), and extended instructions (53.6%) suggest it handles scientific and engineering workloads with ease, as long as those workloads do not rely heavily on encryption.

The Xeon D-1746TER, by contrast, finds its niche in two specific areas. Its 30.8% advantage in PassMark data encryption indicates that it is better equipped for cryptographic workloads, such as secure communications, VPN termination, or encrypted storage. Its 19.1% lead in find prime numbers points to a strength in certain mathematical operations, possibly related to its larger L2 cache per core or architectural optimizations in the Ice Lake-D design. For users running these types of tasks, the Xeon offers measurable performance benefits.

Beyond those two tests, the Xeon's advantages are structural rather than performance-based. It supports ECC memory, which is essential for data integrity in server environments, and it offers triple-channel memory with higher bandwidth (64.0 GB/s vs 46.9 GB/s). Its PCIe Gen 4 interface doubles the I/O bandwidth of the i7-10700K's Gen 3, making it more suitable for systems with high-speed storage or multiple accelerators. The lower TDP of 67 watts also makes it an efficiency choice for dense server deployments, where power and cooling are constrained.

For general desktop use, gaming, and most productivity applications, the benchmark data points squarely to the i7-10700K. For encrypted data handling, prime-number-intensive math, and server-specific features like ECC and PCIe Gen 4, the Xeon D-1746TER is the better fit.

The Verdict

The benchmark database makes the distinction easy to summarize. The Intel Core i7-10700K wins 15 of 17 head-to-head tests and leads by double digits in most of them. Its single-thread dominance, with a 70.5% margin in PassMark, is the defining statistic. Anyone choosing between these two for desktop-class performance should select the i7-10700K without hesitation. It is faster in rendering, math, compression, sorting, and physics, and it includes integrated graphics and an unlocked multiplier for additional flexibility.

The Intel Xeon D-1746TER is not without merit, but its strengths are narrow. It wins in data encryption by 30.8% and in prime-number finding by 19.1%, making it a specialized tool for those specific tasks. Its server-oriented features, including ECC memory support, triple-channel DDR4 with 64.0 GB/s bandwidth, and PCIe Gen 4, are valuable in enterprise deployments where reliability and I/O throughput matter more than raw compute speed. Its lower 67-watt TDP also makes it an efficient option for always-on server workloads.

The decision ultimately comes down to the workload. If the task is encryption-heavy or requires server-grade memory and I/O features, the Xeon D-1746TER is the appropriate choice. If the task involves general computing, content creation, or any of the many workloads where the i7-10700K leads by 18% or more, the Core chip is the superior processor. The data does not support the Xeon as a general-purpose winner, but it does carve out a legitimate, if limited, role for it.
