Intel Core 3 N355 vs NVIDIA RTX Spark (MediaTek AHJ11488B) Comparison

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the Intel Core 3 N355 and the NVIDIA RTX Spark (MediaTek AHJ11488B). The headToHeadBenchmarks array is empty, and both winsA and winsB are recorded as zero. This means direct comparative scores, such as Cinebench R23 multi-core or PassMark single-thread results, are not available for these two processors in the recorded data.

The Intel Core 3 N355, however, has a full benchmark suite captured. Its Cinebench R23 multi-core score is 5262, with a single-core score of 1039. In Cinebench R20, the multi-core result is 3612 and single-core is 509. The older Cinebench R15 test shows 822 multi-core and 168 single-core. PassMark results include a multi-thread score of 10174, a single-thread score of 2153, integer math at 33894, floating-point math at 22695, data compression at 117435, data encryption at 8121, extended instructions at 5968, prime number finding at 27, physics at 625, and random string sorting at 14706. The average benchmark score for the N355 is 13492, placing it in the 68th percentile among all CPUs tracked.

The NVIDIA RTX Spark (MediaTek AHJ11488B) has no benchmark records in the database. Its avgBenchmarkScore is listed as 0, and its percentileVsAllCpus is 50. Without measured scores, any head-to-head comparison relies solely on architectural specifications and the known performance of the N355 relative to its nearest rivals.

The N355's nearest rivals provide context for its performance tier. The Intel Core i3-12100F has an average score of 13494, a delta of 0% from the N355. The Intel Core i5-9500 scores 13452, which is 0.3% higher than the N355. The Intel Core 5 120UL scores 13594, putting it 0.8% ahead. The Intel Core i7-1250U scores 13351, which is 1.1% behind the N355. These deltas show the N355 sits in a tight cluster, with all four rivals within roughly a 1% band of its average score.

Architecture Differences

The two processors diverge sharply at the architectural level. The Intel Core 3 N355 uses the Twin Lake architecture, with a codename of Twin Lake and a generation label of Core 3 (Alder Lake-N). It is built on a 10 nm process node at Intel's own foundry, with 8 cores and 8 threads. The base clock is 1.90 GHz and the boost clock is 3.90 GHz. Its thermal design power (TDP) is 15 watts, and it uses the Intel BGA 1264 socket.

The NVIDIA RTX Spark (MediaTek AHJ11488B) presents a different profile. It has 20 cores and 20 threads, a base clock of 1.70 GHz, and a boost clock of 4.00 GHz. The TDP is 38 watts. The process node is 3 nm, fabricated by TSMC, and the die size is 208 mm². The codename is N1X, with a generation label of Spark (GB10). No socket is listed for this part, and the integrated graphics are listed as GB20B "Blackwell".

Cache hierarchies differ substantially. The N355 has 96 KB of L1 cache per core, 2 MB of shared L2 cache, and 6 MB of shared L3 cache. The RTX Spark has 128 KB of L1 per core, 2 MB of L2 per core, and 8 MB of shared L3 cache. The per-core L2 allocation on the RTX Spark is notably larger, which can affect data locality and latency for workloads that reuse working sets.

Memory support is another clear split. The N355 supports DDR4, DDR5, and LPDDR5 memory, but only through a single-channel memory bus, delivering a memory bandwidth of 38.4 GB/s. The RTX Spark supports LPDDR5X memory on a quad-channel bus, with memory bandwidth of 273.1 GB/s. That is a substantial difference in raw memory throughput, which can influence tasks like data compression and encryption, though neither chip has direct benchmark scores to verify this in the database.

PCIe connectivity also differs. The N355 uses PCIe Gen 3 with 9 lanes (CPU only). The RTX Spark lists PCIe as N/A, indicating no standard PCIe support is recorded. The N355's integrated graphics are UHD Graphics 770, while the RTX Spark uses GB20B "Blackwell". Neither chip has ECC memory support, and neither has an unlocked multiplier.

Where Each One Wins

Based on the recorded data, the Intel Core 3 N355 is the only one with measurable benchmark results, so it wins every category where a score exists. Its average benchmark score of 13492 places it in the 68th percentile of all CPUs, which indicates it outperforms a majority of tracked processors. The nearest rival, the Intel Core i3-12100F, matches it exactly at 13494, suggesting the N355 delivers comparable multi-threaded performance to a desktop-oriented quad-core chip.

The RTX Spark, by contrast, has no benchmark scores, so its wins cannot be quantified from the database. Its architectural specifications, however, suggest potential strengths in specific workloads. The 20 cores and 20 threads, combined with a 4.00 GHz boost clock, could benefit heavily threaded tasks. The quad-channel LPDDR5X memory with 273.1 GB/s bandwidth is far higher than the N355's 38.4 GB/s, which could advantage memory-bound operations such as large data sorting or streaming workloads. The larger L2 cache per core (2 MB versus 2 MB shared across all cores on the N355) may also reduce memory latency for per-core data sets.

The N355's strengths are more evident from its benchmark data. In PassMark single-thread, it scores 2153, which is a solid result for a mobile chip. Its multi-thread score of 10174, combined with a Cinebench R23 multi-core score of 5262, shows it handles parallel workloads reasonably well given its 15-watt TDP. The low power envelope is a clear advantage for fanless or thermally constrained mobile designs, though the database does not record any power-efficiency scores.

For use cases, the N355 appears suited to general productivity, light multi-threaded content creation, and everyday computing, based on its benchmark profile. The RTX Spark, with its higher core count, larger memory bandwidth, and 3 nm process, is architecturally positioned for more demanding compute, but without benchmark data, any performance claim remains speculative.

The Verdict

The data indicates the Intel Core 3 N355 is a complete, measurable product. It has an active production status, a release date of January 2025, and a full benchmark profile. Its average score of 13492 and 68th percentile ranking confirm it performs in line with established desktop chips like the Core i3-12100F and Core i5-9500, both within 0.3% of its average score. For users needing a low-power mobile processor with proven multi-threaded and single-threaded results, the N355 is the only choice with recorded performance evidence.

The NVIDIA RTX Spark (MediaTek AHJ11488B) is unreleased, with no benchmarks and no nearest rivals in the database. Its specifications suggest a more powerful part on paper: 20 cores, a 4.00 GHz boost, 273.1 GB/s memory bandwidth, and a 3 nm process. But the absence of any measured scores means the database cannot confirm these advantages translate into real-world wins. Its production status is listed as unreleased, with a release date of December 2025.

The verdict from the recorded data is straightforward: the N355 is the only processor with substantiated performance. The RTX Spark remains an unmeasured entity, promising on architecture but unverified in benchmarks. For any comparative analysis, the N355's scores stand as the sole reference point.
