Intel Core 3 N350 vs Intel Xeon Gold 6346 Comparison

Head-to-Head Benchmarks

The benchmark data delivers a decisive verdict: the Intel Xeon Gold 6346 wins every single head-to-head test, and it does so by a consistent and commanding margin. Across all six Cinebench comparisons, the Xeon Gold 6346 outperforms the Intel Core 3 N350 by exactly 80.2%. This uniformity is striking, as it indicates a fundamental performance gap rather than workload-specific variability.

In Cinebench R23 multi-core, the Xeon Gold 6346 scores 31,650 against the Core 3 N350's 6,274. The single-core R23 test shows the same pattern: 4,468 versus 885. Moving to Cinebench R20, the Xeon Gold 6346 posts 13,293 in multi-core and 1,876 in single-core, while the Core 3 N350 manages 2,635 and 371 respectively. In the older Cinebench R15 suite, the Xeon Gold 6346 scores 3,190 multi-core and 450 single-core, dwarfing the Core 3 N350's 632 and 89.

The delta of 80.2% appears in every test, from the most thread-hungry multi-core workload to the lightly threaded single-core run. This means the Xeon Gold 6346 is not merely stronger in parallel tasks; it holds the same relative advantage even when only one core is active. For the Core 3 N350, there are no benchmark wins to report. The database records zero wins for the Core 3 N350 and six wins for the Xeon Gold 6346.

Where Each One Wins

The Xeon Gold 6346 is the clear winner across all measured categories, but the nature of its wins matters for practical use. Its multi-core dominance is expected given its 16 cores and 32 threads, but the single-core results are equally important. The Xeon Gold 6346's single-core scores are not just higher, they are higher by the same 80.2% margin, which suggests a substantial per-core performance advantage, not just a core-count advantage.

For compute-heavy server and workstation tasks, the Xeon Gold 6346's Cinebench R23 multi-core score of 31,650 places it in a different performance class entirely. The Core 3 N350's 6,274 is a modest result, typical of a low-power part. The data shows the Xeon Gold 6346 excels in sustained multi-threaded rendering, simulation, and any workload that scales with core count.

The Core 3 N350's strengths are not visible in these head-to-head benchmarks. However, its overall profile suggests a different role. Its average benchmark score of 9,903 places it in the 66th percentile of all CPUs, slightly above the Xeon Gold 6346's 65th percentile and 9,155 average. This is a notable inversion: the Xeon Gold 6346 wins every direct comparison, yet the Core 3 N350 has a higher average score across all database benchmarks. This reflects the Core 3 N350's strong showing in its nearest rival group, where it sits close to the Intel Core i7-3770 (2% higher) and Intel Core i5-1035G1 (2.3% higher), while trailing the AMD EPYC 7F52 by 2.5% and the Intel Xeon Platinum 8280 by 3.2%.

The Xeon Gold 6346's nearest rivals tell a different story. It is 0.9% behind the Intel Xeon Gold 5320, 0.9% behind the Intel Core i7-1165G7, 0.9% behind the Intel Core i5-10300H, and 1.1% ahead of the Intel Core i5-1135G7. These are tight margins, indicating the Xeon Gold 6346 sits in a crowded performance band despite its head-to-head superiority over the Core 3 N350.

The Verdict

The data is unambiguous: the Intel Xeon Gold 6346 is the superior processor in every direct benchmark comparison. Anyone choosing between these two for raw compute performance should select the Xeon Gold 6346 without hesitation. Its 80.2% lead in every Cinebench test, from single-core to multi-core, leaves no room for debate.

The Xeon Gold 6346 is the choice for server and workstation workloads that demand high throughput. Its 16 cores and 32 threads, combined with a 36 MB shared L3 cache and eight-channel memory bus, are designed for exactly this purpose. The Core 3 N350, with 8 cores and 8 threads, a 6 MB shared L3 cache, and a single-channel memory bus, cannot compete in this arena.

However, the Core 3 N350 is not without a rationale. Its 7 W TDP is a stark contrast to the Xeon Gold 6346's 205 W TDP. The Core 3 N350 is a mobile part, built for efficiency and low power consumption. Its higher average benchmark score of 9,903 versus 9,155 suggests that in a broader context, it holds its own against many desktop and mobile processors. For a fanless or battery-powered system, the Core 3 N350 is the only sensible option, as the Xeon Gold 6346's power draw would be prohibitive.

The verdict depends entirely on the use case. For maximum performance, the Xeon Gold 6346 wins decisively. For minimum power draw, the Core 3 N350 is the only viable choice. The data does not support any middle ground.

The Core 3 N350 has a base clock of 0.10 GHz and a boost clock of 3.90 GHz, while the Xeon Gold 6346 has a base clock of 3.10 GHz and a boost clock of 3.60 GHz. The Xeon Gold 6346's base clock is far higher, while the Core 3 N350's boost clock is slightly higher.

TDP is a major differentiator: the Core 3 N350 draws 7 W, the Xeon Gold 6346 draws 205 W. The Core 3 N350 uses an Intel BGA 1264 socket, while the Xeon Gold 6346 uses an Intel Socket 4189. The Core 3 N350 is classified as a mobile part, while the Xeon Gold 6346 is a server or workstation part.

The Core 3 N350 supports DDR4, DDR5, and LPDDR5 memory, while the Xeon Gold 6346 supports only DDR4. The memory bus is single-channel on the Core 3 N350 versus eight-channel on the Xeon Gold 6346, with bandwidths of 38.4 GB/s and 204.8 GB/s respectively. ECC memory is supported only on the Xeon Gold 6346. PCIe lanes are 9 (Gen 3) for the Core 3 N350 and 64 (Gen 4) for the Xeon Gold 6346.
