Intel Core 7 350 vs Intel Core Ultra 7 270K Plus Comparison

The Intel Core 7 350 and Intel Core Ultra 7 270K Plus occupy different segments of the performance spectrum, with the recorded data showing no benchmark wins for the Core 7 350 across all 17 head-to-head tests. The Core Ultra 7 270K Plus delivers a dominant multi-threaded performance advantage, with the gap ranging from roughly 71% to 83% depending on the workload. The Core 7 350, by contrast, is a mobile-oriented part with a 15 W TDP, designed for efficiency rather than raw throughput. The data indicates these processors are not direct competitors but rather solutions for distinct use cases, one prioritizing sustained low-power operation and the other maximizing computational output.

The Verdict

The benchmark results are unambiguous: the Intel Core Ultra 7 270K Plus is the superior processor for any workload that demands high compute throughput. Its average benchmark score of 93785 places it in the 96th percentile of all CPUs, while the Intel Core 7 350 sits at the 71st percentile with an average score of 17779. The Core Ultra 7 270K Plus outperforms the Core 7 350 in every recorded test, with the most significant deltas appearing in multi-threaded scenarios. In Cinebench R23 multi-core, the Ultra 7 scores 44253 compared to 8030 for the Core 7 350, a difference of 81.9%. This pattern repeats across PassMark workloads, including data compression (804322 vs 143123, an 82.2% delta) and integer math (175986 vs 33734, an 80.8% delta).

The Core Ultra 7 270K Plus also holds a clear single-thread advantage, though the margin is smaller. Its PassMark single-thread score of 5068 exceeds the Core 7 350's 4100 by 19.1%. Cinebench R23 single-core shows a 16.1% delta (2439 vs 2046). This indicates that even in lightly threaded applications, the Ultra 7 270K Plus delivers measurably higher performance, a result consistent with its higher boost clock of 5.50 GHz versus 4.80 GHz.

The Intel Core 7 350 is not without merit, but its strengths lie outside raw performance. It is a mobile processor with a 15 W TDP, a single-channel memory bus, and a compact BGA 1516 package. The data shows it competes with processors like the Intel Core 5 120U, which scores 17898 and is only 0.7% ahead, and the AMD Ryzen 5 3600XT, which scores 17891 and is 0.6% ahead. For users constrained by power and thermal limits, the Core 7 350 offers a viable balance, but the database records no scenario where it outperforms the Core Ultra 7 270K Plus.

The verdict from the data is straightforward: the Core Ultra 7 270K Plus is the choice for desktop users who need maximum performance and can accommodate a 125 W TDP. The Core 7 350 targets mobile platforms where efficiency is paramount and performance expectations are lower.
