Head-to-Head Benchmarks

The data is unambiguous: the Intel Core i9-14900KS wins all 17 recorded head-to-head benchmarks against the Intel Core 7 350, with the smallest margin being a 14.8% lead in single-thread performance. The largest gaps appear in heavily multi-threaded workloads, where the Core i9-14900KS more than sextuples the Core 7 350's scores.

In Cinebench R23 multi-core, the Core i9-14900KS scores 50,995 versus 8,030 for the Core 7 350, a delta of -84.3% for the smaller chip. That is the widest multi-core gap in the entire comparison. The R20 multi-core test shows a similar pattern: 21,417 versus 5,373, a 74.9% deficit. The R15 multi-core test records 5,140 versus 1,220, also a 76.3% deficit.

Single-core results are closer but still favor the Core i9-14900KS decisively. In Cinebench R23 single-core, the Core i9-14900KS posts 7,199 against 2,046, a 71.6% lead.

Where Each One Wins

The Intel Core i9-14900KS wins every workload category in the database. Its largest advantages concentrate in multi-core rendering, integer math, and data compression, where its 24 cores and 32 threads overwhelm the Core 7 350's 6 cores and 6 threads. The Cinebench R23 multi-core result, the 84.3% gap, is the single most decisive data point, indicating a massive advantage for CPU-bound rendering tasks.

The Core 7 350's narrowest deficit appears in the PassMark single-thread test, where the 14.8% gap suggests that per-clock efficiency is relatively competitive. The Core i9-14900KS boosts to 6.20 GHz, which explains its single-thread edge, but the Core 7 350's 4.80 GHz boost still keeps it within striking distance in lightly threaded workloads.

For workloads that depend on raw multi-threading, such as video rendering, 3D simulation, or large-scale data processing, the Core i9-14900KS is categorically dominant. For light, single-threaded tasks like web browsing or office productivity, the Core 7 350 is not far behind, though still measurably slower in every recorded test.

The Core 7 350's advantages lie outside raw compute. It carries a 15 TDP versus 150 TDP, a difference that points to dramatically lower power draw. It uses a 3 nm process node versus 10 nm, and it supports LPDDR5X memory. These factors are not reflected in the benchmark scores but matter for platform-level considerations. The Core 7 350 also integrates Intel Xe3 Graphics with 2 Xe cores, while the Core i9-14900KS uses UHD Graphics 770.

The Verdict

The benchmark data supports a single conclusion: the Intel Core i9-14900KS is the overwhelmingly faster processor in every measured workload. Its 17 wins out of 17 head-to-head tests leave no ambiguity. The most extreme advantage is 84.3% in Cinebench R23 multi-core, and the smallest is 14.8% in PassMark single-thread. The Core i9-14900KS sits at the 96th percentile of all CPUs, while the Core 7 350 sits at the 71st percentile. Its average benchmark score is 81,127 versus 17,779, a 4.6x difference.

The Core 7 350 is not competitive on raw performance.

The Core i9-14900KS's nearest rivals are the Intel Xeon w5-3535X, AMD Ryzen 9 8940HX, AMD Ryzen AI Max+ PRO 395, and Intel Xeon 638, all within 0.5% of its average.

The Core 7 350 does offer a distinct platform profile: a 3 nm mobile chip with 15 TDP, LPDDR5X support, and a single-channel memory bus. For a low-power mobile system, those characteristics matter. The Core i9-14900KS is a desktop part with 150 TDP, dual-channel memory, and 36 MB L3, built for maximum throughput.

Who should pick the Core i9-14900KS: anyone whose workloads are dominated by multi-threaded compute, based on the 84.3% multi-core lead, the 82.2% data compression advantage, and the 84.1% integer math margin. The 96th percentile ranking confirms its position among the fastest CPUs in the database.

Who should pick the Core 7 350: anyone constrained by a 15 TDP power envelope, a mobile socket, or a preference for the 3 nm process node. Its 71st percentile ranking places it in the upper range of all CPUs, and its single-thread performance is only 14.8% behind the Core i9-14900KS in the closest recorded test. For light workloads on battery-powered hardware, the Core 7 350 is the only viable choice between these two. For anything demanding, the data selects the Core i9-14900KS without qualification.
