AMD Ryzen 7 7700X3D vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The database contains no overlapping benchmark results for the AMD Ryzen 7 7700X3D and the Intel Core 3 305. The AMD part has no recorded benchmark scores in the database, while the Intel Core 3 305 has 17 recorded results across Cinebench and Passmark tests. Consequently, a direct head-to-head comparison cannot be established from the recorded data. The Intel Core 3 305's average benchmark score is 18,302, placing it at the 72nd percentile among all CPUs. Its nearest rivals in the database are the Intel Core i3-14100 (average score 18,318, delta -0.1%), the Intel Core 5 330 (average score 18,345, delta -0.2%), the Intel Core 7 360 (average score 18,374, delta -0.4%), and the AMD Ryzen 5 2600E (average score 18,230, delta +0.4%). These deltas indicate that the Core 3 305 sits within a tight performance cluster, less than half a percent away from all four nearest rivals.

Since the AMD Ryzen 7 7700X3D has no benchmark entries, the analysis must rely on its architectural specifications rather than measured performance. The Core 3 305's single-thread results are notable: Cinebench R15 single-core score of 186, R20 single-core score of 777, and R23 single-core score of 1,852. The Passmark single-thread score is 3,977. In multithreaded workloads, the Core 3 305 records Cinebench R15 multicore 1,322, R20 multicore 5,511, and R23 multicore 13,123. The Passmark multithread score is 15,439. The Core 3 305 also shows strong integer math performance at 32,295 and floating point math at 42,284 in Passmark. Data compression scores 146,857, while data encryption scores 11,019. Extended instruction performance is 13,543, and random string sorting is 17,623. Physics in Passmark records 1,233, and prime number finding records 115.

The absence of AMD benchmark data means the biggest wins in either direction cannot be quantified. The recorded data shows only the Intel part's performance profile. The AMD Ryzen 7 7700X3D has no wins recorded, and the Intel Core 3 305 has no wins recorded, because the head-to-head benchmark array is empty.

The Verdict

The database shows that the Intel Core 3 305 is the only one of the two processors with measured performance data, and its average benchmark score of 18,302 places it at the 72nd percentile among all CPUs. Its nearest rival, the Intel Core i3-14100, scores 18,318, a delta of -0.1%, meaning the Core 3 305 trails by one tenth of one percent. Against the Intel Core 5 330 (18,345, -0.2%) and the Intel Core 7 360 (18,374, -0.4%), the Core 3 305 trails by similarly small margins. Against the AMD Ryzen 5 2600E (18,230, +0.4%), the Core 3 305 leads by four tenths of one percent. These figures indicate that the Core 3 305 performs at parity with its closest competitors, with all four rivals within a 0.4% band.

The AMD Ryzen 7 7700X3D presents a different case. With no benchmark scores in the database, its measured performance cannot be compared. The specifications show an 8-core, 16-thread desktop processor on AMD Socket AM5, with a base clock of 4.00 GHz and a boost clock of 4.50 GHz. The Intel Core 3 305 is a 6-core, 6-thread mobile processor on Intel BGA 1516, with a base clock of 1.50 GHz and a boost clock of 4.30 GHz. The recorded data does not support a verdict that either processor is faster overall. The Intel part has the only measured results, so any statement about the AMD part's performance would not be grounded in database measurements. The verdict from the data is that the Core 3 305 is a mid-pack performer relative to all CPUs, while the 7700X3D's performance category remains unmeasured in this database.

Where Each One Wins

The Intel Core 3 305 wins in terms of measured data availability. Its 17 benchmark results cover both Cinebench and Passmark suites, providing a complete performance profile. The Core 3 305's closest performance parity is with the Intel Core i3-14100, trailing by only 0.1%. It also trails the Intel Core 5 330 and Intel Core 7 360 by 0.2% and 0.4% respectively, while leading the AMD Ryzen 5 2600E by 0.4%. The Core 3 305's single-thread Passmark score of 3,977 and multithread score of 15,439 define its workload profile. Its Cinebench R23 scores of 13,123 multicore and 1,852 single-core show a 7.1:1 ratio between multithreaded and single-threaded performance, indicating that the processor scales reasonably well across cores despite having 6 threads for 6 cores.
