Intel Core 7 350 vs Intel Core Ultra 5 245KF Comparison

Intel Core 7 350 and Intel Core Ultra 5 245KF are two processors from different segments of Intel’s lineup, one a low-power mobile part and the other a high-performance desktop chip. The benchmark data shows a complete sweep for the Core Ultra 5 245KF across all 17 recorded head-to-head tests, with the Core 7 350 failing to secure a single win. The Core Ultra 5 245KF also sits in the 91st percentile of all CPUs, while the Core 7 350 sits in the 71st percentile. The average benchmark score for the Core Ultra 5 245KF is 55093, compared to 17779 for the Core 7 350, a gap that reflects the fundamental difference in their design targets.

Where Each One Wins

The Core 7 350 does not win any recorded benchmark comparison. Across the entire head-to-head dataset, the Core Ultra 5 245KF posts a higher score in every single test, from Cinebench render loads to PassMark math and encryption workloads. The Core 7 350’s closest margin is in PassMark single-thread performance, where it scores 4100 against the Core Ultra 5 245KF’s 4715, a 13% deficit. That is the smallest gap between the two chips in any test, but it is still a loss.

The Core Ultra 5 245KF wins everywhere else by a much larger margin. In Cinebench R23 multi-core, it scores 36647 versus 8030 for the Core 7 350, a 78.1% advantage. In PassMark integer math, the Core Ultra 5 245KF scores 98854 against 33734, a 65.9% lead. The largest relative gaps appear in workloads that scale with core count and memory bandwidth, which is expected given the Core Ultra 5 245KF’s 14 cores versus 6 for the Core 7 350, and its dual-channel memory bus versus single-channel on the mobile part. The Core Ultra 5 245KF also leads in single-threaded tests, where core count matters less, indicating a higher per-core performance as well.

The Verdict

The data indicates that the Core Ultra 5 245KF is the stronger processor in every measured workload. Its 91st percentile ranking, average score of 55093, and 14-core configuration place it in a different performance class than the Core 7 350, which manages a 71st percentile ranking and an average score of 17779. The Core Ultra 5 245KF delivers a 64.8% lead in PassMark multi-thread, a 60.4% lead in Cinebench R23 single-core, and a 68.9% lead in data compression. For any workload represented in the database, the Core Ultra 5 245KF is the faster choice.

The Core 7 350 still has a role, but not as a performance leader. It is a mobile processor with a 15 W TDP, integrated Xe3 graphics, and a single-channel memory bus, designed for power efficiency rather than raw throughput. Its launch MSRP is $469, which is higher than the Core Ultra 5 245KF’s $294, but the Core 7 350 targets low-power laptops and compact systems where cooling and battery life take priority. The Core Ultra 5 245KF is a desktop part with a 125 W TDP, no integrated graphics, and an unlocked multiplier, suited for builds where performance is the primary goal. Users who need the fastest benchmark results should choose the Core Ultra 5 245KF. Users who need a low-power mobile chip with integrated graphics should consider the Core 7 350 despite its lower scores.

Head-to-Head Benchmarks

The largest win for the Core Ultra 5 245KF comes in Cinebench R23 multi-core, where it scores 36647 against 8030 for the Core 7 350, a 78.1% advantage. This test benefits heavily from the Core Ultra 5 245KF’s 14 cores and 24 MB of shared L3 cache, compared to 6 cores and 6 MB of L3 on the Core 7 350. The Core 7 350’s 6 threads match its 6 cores, so there is no hyper-threading benefit to close the gap.

In Cinebench R20 multi-core, the Core Ultra 5 245KF scores 15391 versus 5373, a 65.1% lead. The single-core version of R20 shows the Core Ultra 5 245KF at 2172 against 758, also a 65.1% gap. Cinebench R15 follows the same pattern: multi-core 3693 versus 1220 for a 67% lead, single-core 521 versus 292 for a 44% lead. The single-core gap narrows compared to the multi-core results, but the Core Ultra 5 245KF still holds a commanding edge.

PassMark tests show consistent leads for the Core Ultra 5 245KF. Data compression scores 460123 versus 143123, a 68.9% advantage. Data encryption scores 33381 versus 10933, a 67.2% lead. Extended instructions score 37912 versus 12045, a 68.2% lead. Find prime numbers scores 416 versus 107, a 74.3% lead. Floating point math scores 131546 versus 42809, a 67.5% lead. Integer math scores 98854 versus 33734, a 65.9% lead. Multi-thread score is 43110 versus 15170, a 64.8% lead. Physics scores 2998 versus 1173, a 60.9% lead. Random string sorting scores 55206 versus 17238, a 68.8% lead.

The smallest gap in the entire dataset is PassMark single-thread, where the Core Ultra 5 245KF scores 4715 against 4100 for the Core 7 350, a 13% lead. This shows the Core 7 350’s Wildcat Lake architecture has competitive single-thread capability, but not enough to match the Core Ultra 5 245KF’s Arrow Lake design. The Core Ultra 5 245KF also has a higher boost clock at 5.20 GHz versus 4.80 GHz for the Core 7 350, which contributes to this single-thread advantage.
