AMD Ryzen 7 7700X3D vs Intel Core 3 N350 Comparison

The Verdict

The data positions these two processors for entirely different markets. The AMD Ryzen 7 7700X3D is a desktop part with 8 cores and 16 threads, a 120 W TDP, and a 4.50 GHz boost clock. The Intel Core 3 N350 is a mobile part with 8 cores and 8 threads, a 7 W TDP, and a 3.90 GHz boost clock. The benchmark records for the Intel part show scores in Cinebench R15, R20, and R23, plus PassMark tests; the AMD part has no recorded benchmark scores in the database. The Intel Core 3 N350 sits at the 66th percentile among all CPUs, while the AMD Ryzen 7 7700X3D sits at the 50th percentile, though that percentile is based on no recorded measurements. The Intel part has an average benchmark score of 9,903 across its recorded tests. The AMD part has an average benchmark score of 0 because no benchmarks are listed. The database therefore only supports a direct performance comparison for the Intel processor, while the AMD processor must be assessed on specifications alone.

From the recorded data, the Intel Core 3 N350 is the only part with measurable benchmark results. Its Cinebench R23 multicore score of 6,274 and single-core score of 885 indicate a modest level of throughput. The AMD Ryzen 7 7700X3D, with 16 threads versus 8, a 4.50 GHz boost clock versus 3.90 GHz, 96 MB of shared L3 cache versus 6 MB, and DDR5 dual-channel memory support versus single-channel DDR4/DDR5/LPDDR5, carries specifications that should deliver substantially higher performance in multi-threaded and memory-sensitive workloads. The AMD part also uses a 5 nm process node from TSMC, while Intel uses a 10 nm node from its own foundry. The verdict for a buyer depends on the use case: the Intel Core 3 N350 fits low-power mobile systems where the 7 W TDP and integrated UHD Graphics 770 are primary assets; the AMD Ryzen 7 7700X3D targets desktop builds where the 120 W TDP and 96 MB L3 cache are acceptable trade-offs for higher compute capability.

Architecture Differences

The two processors come from different manufacturing and design lineages. The AMD Ryzen 7 7700X3D belongs to the 7000 series, uses the Raphael codename, and is built on a 5 nm process node at TSMC. It has 11,270 million transistors on a 71 mm² die. Its generation is listed as Ryzen 7 (Zen 4 (Raphael)). The Intel Core 3 N350 uses the Twin Lake architecture, which is part of the Core 3 (Alder Lake-N) generation, and is built on a 10 nm process node at Intel. The Intel part has no transistor count or die size recorded.

Cache organization differs significantly. The AMD part provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 96 MB of shared L3 cache. The Intel part provides 96 KB of L1 cache per core, 2 MB of shared L2 cache, and 6 MB of shared L3 cache. The AMD part has a total L3 pool that is 16 times larger than the Intel part, which matters for workloads with large working sets. The AMD processor uses a dual-channel memory bus with DDR5 support and a recorded memory bandwidth of 83.2 GB/s. The Intel processor uses a single-channel memory bus with support for DDR4, DDR5, and LPDDR5, and a recorded memory bandwidth of 38.4 GB/s. The AMD part supports ECC memory; the Intel part does not. The AMD part runs on AMD Socket AM5, while the Intel part uses Intel BGA 1264, which is a soldered mobile socket. The AMD part offers PCIe Gen 5 with 24 lanes (CPU only), while the Intel part offers PCIe Gen 3 with 9 lanes (CPU only). The AMD part includes Radeon Graphics; the Intel part includes UHD Graphics 770.

Head-to-Head Benchmarks

The database has no head-to-head benchmark entries for these two processors, and the AMD Ryzen 7 7700X3D has no benchmark scores at all. The only recorded benchmark data belongs to the Intel Core 3 N350. Its Cinebench R15 multicore score is 632, and its single-core score is 89. In Cinebench R20, the multicore score is 2,635, and the single-core score is 371. In Cinebench R23, the multicore score is 6,274, and the single-core score is 885. PassMark results for the Intel part include a multithread score of 7,382, a single-thread score of 1,974, integer math at 27,669, floating-point math at 17,781, data compression at 80,444, data encryption at 5,693, extended instructions at 3,981, find prime numbers at 20, physics at 446, and random string sorting at 10,102.

Because the AMD part has no recorded scores, any head-to-head comparison must rely on the specification deltas. The AMD part has a base clock of 4.00 GHz versus the Intel part's 0.10 GHz base clock, and a boost clock of 4.50 GHz versus 3.90 GHz. The AMD part has 16 threads versus 8. The AMD part has 96 MB of L3 cache versus 6 MB. The AMD part has dual-channel memory versus single-channel. These differences indicate that the AMD part should outperform the Intel part in multi-threaded workloads, memory bandwidth-sensitive tasks, and large dataset processing. The Intel part, with a 7 W TDP, will run at far lower power draw and is designed for efficiency.

Where Each One Wins

The Intel Core 3 N350 wins in power efficiency. Its 7 W TDP is dramatically lower than the AMD part's 120 W TDP, making it suitable for fanless or passively cooled mobile devices, thin laptops, or embedded systems where heat and battery life are the dominant constraints. Its integrated UHD Graphics 770 provides a graphics solution without a discrete GPU. The Intel part also has a recorded benchmark profile, so its performance is verifiable: it ranks at the 66th percentile among all CPUs, with an average score of 9,903. Its nearest rivals in the database include the Intel Core i7-3770 (average score 9,706, delta 2%), the Intel Core i5-1035G1 (average score 9,684, delta 2.3%), the AMD EPYC 7F52 (average score 10,159, delta -2.5%), and the Intel Xeon Platinum 8280 (average score 10,230, delta -3.2%). This places the Intel part slightly above older desktop i7 parts and slightly below server-class chips.

The AMD Ryzen 7 7700X3D wins in raw specification potential. It has a higher boost clock (4.50 GHz versus 3.90 GHz), double the threads (16 versus 8), a much larger L3 cache (96 MB versus 6 MB), a dual-channel memory bus with 83.2 GB/s bandwidth versus 38.4 GB/s, and PCIe Gen 5 support versus Gen 3. It uses a 5 nm process node, which is physically more advanced than the 10 nm node in the Intel part. The AMD part supports ECC memory, which matters for error-sensitive workloads. It is a desktop part on Socket AM5, meaning it can be paired with high-performance discrete GPUs and fast DDR5 memory. The AMD part has a launch MSRP of $329. The AMD part has no recorded benchmarks, so its actual performance is not quantified in the database, but the specification deltas point to clear advantages in compute-heavy and memory-intensive tasks.
