AMD Ryzen 3 3100U vs Intel Core 3 305 Comparison

Head-to-Head Benchmarks

The recorded data presents a one-sided comparison. The Intel Core 3 305 wins all 11 head-to-head benchmark tests against the AMD Ryzen 3 3100U. The closest margin appears in single-thread performance, where the Intel part scores 3977 against the AMD's 1592, a 60% advantage. This is still a substantial gap, but it is the narrowest of the eleven contests.

The largest deltas appear in floating-point math and extended instructions. In floating-point math, the Intel Core 3 305 scores 42284 while the AMD Ryzen 3 3100U manages 5854, a deficit of 86.2% for the AMD chip. Extended instructions show a similar pattern: 13543 for Intel versus 2116 for AMD, an 84.4% shortfall. These two tests point to a significant difference in raw computational throughput per clock and per core.

Data compression and integer math show the smallest percentage gaps outside of single-thread. The Intel part reaches 146857 in data compression against 38455, a 73.8% lead. Integer math sees 32295 versus 8873, a 72.5% delta. Random string sorting shows a 73.5% gap, with Intel at 17623 and AMD at 4666. Encryption, prime number finding, physics, and multithreaded workloads all fall in the 78% to 84% range, with Intel ahead in every case.

The multithread test deserves attention because the core counts differ. The AMD Ryzen 3 3100U has 2 cores and 2 threads, while the Intel Core 3 305 has 6 cores and 6 threads. In the passmark multithread test, Intel scores 15439 versus AMD's 3348, a 78.3% advantage. The Intel chip also leads in physics, scoring 1233 against 232, an 81.2% margin. Prime number finding, often a test that rewards single-core efficiency, sees Intel at 115 versus 18, an 84.3% gap.

The average benchmark score tells a similar story. The Intel Core 3 305 averages 18302 across its recorded benchmarks, while the AMD Ryzen 3 3100U averages 6247. The percentile rankings reinforce this: Intel sits at the 72nd percentile among all CPUs, while AMD sits at the 62nd. Each processor's nearest rivals confirm the tier gap. The Intel Core 3 305 sits within 0.4% of the Intel Core i3-14100, the Intel Core 5 330, the Intel Core 7 360, and the AMD Ryzen 5 2600E. The AMD Ryzen 3 3100U sits within 1.6% of the AMD Ryzen Threadripper 1950X, the AMD EPYC 7272, the Intel Core i9-10920X, and the Intel Core i9-7940X. These rival clusters suggest the two chips operate in different performance strata despite both targeting mobile markets.

The Verdict

The benchmark data indicates a clear hierarchy. The Intel Core 3 305 outperforms the AMD Ryzen 3 3100U in every measured category. There is no benchmark in the database where the AMD chip wins or ties. The Intel part delivers higher scores in single-threaded work, multithreaded work, encryption, compression, sorting, physics, prime number finding, floating-point math, integer math, and extended instructions.

The AMD Ryzen 3 3100U does not offer a single recorded advantage. Its nearest rivals include high-core-count server and workstation parts like the AMD EPYC 7272 and the AMD Ryzen Threadripper 1950X, with average scores between 6147 and 6347. The Intel Core 3 305, by contrast, sits near the Intel Core i3-14100 and the Intel Core 5 330, with average scores around 18300. The delta between the two chips' average scores is roughly 12000 points, or about 2.9 times the AMD part's total average.

For a buyer choosing strictly on recorded performance, the Intel Core 3 305 is the only defensible pick. The data shows no workload category where the AMD chip comes close. Even in the AMD chip's best relative showing, single-thread performance, it trails by 60%. In every other test, the gap exceeds 72%. The Intel part also reaches the 72nd percentile versus the AMD part's 62nd percentile, which places it higher in the overall CPU distribution.

The AMD Ryzen 3 3100U's production status is listed as Active, and the same is true for the Intel Core 3 305. Both are mobile parts with a 15 TDP. The Intel launch MSRP is $309, stated once here as recorded data. The AMD chip has no launch MSRP in the database. The Intel part also has a newer release date, recorded as 2026-04-15, while the AMD part is dated 2026-05-31. The Intel chip launched about six weeks earlier.

Where Each One Wins

Based on the head-to-head results, the Intel Core 3 305 wins in every benchmark category. There are no wins for the AMD Ryzen 3 3100U in the recorded data. The Intel chip's advantages span all measured workload types: single-threaded tasks, multithreaded tasks, data compression, data encryption, extended instruction sets, prime number finding, floating-point math, integer math, physics simulations, and random string sorting.

The Intel Core 3 305 shows its largest relative advantages in floating-point math (86.2% ahead), extended instructions (84.4%), and prime number finding (84.3%). These tests often stress the processor's execution units and instruction handling. The Intel chip's smallest relative advantage is in single-thread performance at 60%, followed by integer math at 72.5% and random string sorting at 73.5%. Even the smallest gap is decisive.

The AMD Ryzen 3 3100U's recorded data suggests it is a lower-performance mobile processor. Its best benchmark results are 8873 in integer math, 5854 in floating-point math, and 4666 in random string sorting. Its worst results are 18 in prime number finding and 232 in physics. These scores place it below the Intel part in every category, and the percentile data confirms the gap: 62nd versus 72nd.

For use-case planning, the data implies the Intel Core 3 305 handles all recorded workloads with more headroom. The AMD chip might serve in scenarios where the workload is extremely light, but the database shows no recorded test where it matches or exceeds the Intel part. The Intel chip's 6 cores versus 2 cores, and its 6 threads versus 2 threads, provide a structural advantage in multithreaded tests, but the single-thread advantage shows the Intel part also wins on per-core efficiency.
