Its integer math score is 33734, floating point math is 42809, and extended instructions reach 12045. Data compression scores 143123, while data encryption hits 10933. The processor finds prime numbers at a rate of 107, sorts random strings at 17238, and records a physics score of 1173. These results indicate a balanced performer for a mobile processor, but the absence of any benchmark data for the AMD Ryzen 7 7700X3D means the database cannot quantify a direct comparison.

What the data does show is a fundamental asymmetry. The AMD part targets the desktop segment with 8 cores and 16 threads, while the Intel part is a mobile chip with 6 cores and 6 threads. The AMD processor has a base clock of 4.00 GHz and a boost clock of 4.50 GHz, whereas the Intel part has a base clock of 1.50 GHz and a boost clock of 4.80 GHz. The Intel chip reaches a higher peak frequency, but the AMD chip maintains a much higher baseline. The AMD processor carries a TDP of 120 watts, while the Intel processor is rated at just 15 watts, a massive difference in power envelope that directly influences sustained performance.

The recorded data confirms that the Intel Core 7 350 is a capable mobile processor, but the AMD Ryzen 7 7700X3D, with its larger core count, higher base clock, and massive L3 cache, is designed for a different workload profile. The database shows the Intel part's percentile rank at 71, which places it above the median, but the AMD part's percentile is recorded as 50 with an average benchmark score of zero, indicating a lack of measured results rather than a lack of capability.

The Verdict

From the recorded data, the Intel Core 7 350 is a mobile processor with a full set of benchmark scores, while the AMD Ryzen 7 7700X3D has no measured benchmarks in the database. This makes a direct verdict impossible based on performance numbers alone. The Intel part demonstrates solid multi-threaded and single-threaded results, with its Cinebench R23 multi-core score of 8030 and single-core score of 2046 reflecting a processor that handles both parallel and sequential workloads competently. Its PassMark single-thread score of 4100 and multi-thread score of 15170 corroborate this assessment.

The AMD Ryzen 7 7700X3D, however, presents a different profile. With 8 cores and 16 threads, it has more parallel execution resources than the Intel part's 6 cores and 6 threads. Its base clock of 4.00 GHz is substantially higher than the Intel part's 1.50 GHz base, which suggests stronger sustained throughput in multi-threaded scenarios. The AMD processor also carries 96 MB of shared L3 cache, compared to 6 MB for the Intel part, a significant difference that typically benefits workloads with large working sets.

The database shows the Intel part's nearest rivals all cluster within one percent of its average score, indicating that its performance level is well established. The AMD part, by contrast, has no nearest rivals listed, reflecting the absence of benchmark data. The verdict for a user choosing between these two would hinge on the platform: the AMD Ryzen 7 7700X3D is a desktop processor on AMD Socket AM5 with a 120 watt TDP, while the Intel Core 7 350 is a mobile processor on Intel BGA 1516 with a 15 watt TDP. The data supports the Intel part for mobile applications where power efficiency is critical, and the AMD part for desktop workloads where raw multi-threaded capacity and cache size matter more.
