Head-to-Head Benchmarks
The recorded comparison set contains 17 tests. The Core 7 350 wins 15, the Core 3 100U wins 2.
The Core 3 100U's two wins are substantial. In Cinebench R23 multi-core, it scores 10624 against 8030, a 32.3% lead. In PassMark integer math, it scores 39580 against 33734, a 17.3% lead.
The Core 7 350's wins cover single-thread, multi-thread, and specialized workloads. Its largest margin is PassMark find prime numbers: 107 vs 52, a 51.4% lead. Cinebench R15 single-core follows at 292 vs 150, a 48.6% lead. PassMark extended instructions shows 12045 vs 7894, a 34.5% lead. PassMark floating point math shows 42809 vs 28322, a 33.8% lead. Cinebench R23 single-core shows 2046 vs 1499, a 26.7% lead. PassMark data encryption shows 10933 vs 8128, a 25.7% lead. PassMark physics shows 1173 vs 876, a 25.3% lead.
PassMark multithread is notable because the Core 7 350 wins despite having fewer threads: 15170 vs 12522, a 17.5% lead. Cinebench R20 shows 5373 vs 4462 in multi-core and 758 vs 629 in single-core, both with a 17% lead. PassMark single-thread is 4100 vs 3506, a 14.5% lead. Cinebench R15 multi-core is 1220 vs 1070, a 12.3% lead. PassMark random string sorting is 17238 vs 15191, an 11.9% lead. PassMark data compression is 143123 vs 136497, a 4.6% lead. The duplicate PassMark single-thread entries both show the same 14.5% gap.
These results give the Core 7 350 an average benchmark score of 17779 against 16148 for the Core 3 100U.
The Verdict
The recorded data favors the Core 7 350 for the majority of workloads. It wins 15 of 17 tests, has a higher average benchmark score (17779 vs 16148), and ranks at the 71st percentile of all CPUs compared with the 70th percentile for the Core 3 100U. The Core 7 350 also leads in tests where thread count might seem to favor the Core 3 100U, such as PassMark multithread.
The Core 3 100U retains a clear role in the data. Its Cinebench R23 multi-core score is 32.3% ahead, and its PassMark integer math score is 17.3% ahead. For workloads that map to those tests, the Core 3 100U is the stronger part in the database. For workloads that resemble the other 15 tests, the Core 7 350 is the stronger part.
