Intel Core 7 350 vs Intel Core i9-14900 Comparison

Intel Core 7 350 vs Intel Core i9-14900

The Intel Core 7 350 and Intel Core i9-14900 occupy entirely different tiers of Intel's lineup, and the benchmark data reflects that gap clearly. The Core i9-14900 wins every single head-to-head test recorded in the database, with margins ranging from a modest 5.2% in single-threaded workloads to a crushing 80.7% in integer math. The Core 7 350, a mobile-focused 6-core part, holds its own in single-threaded tasks but falls far behind in any workload that scales with core count. The Core i9-14900 sits at the 92nd percentile of all CPUs, while the Core 7 350 lands at the 71st percentile.

Head-to-Head Benchmarks

The most lopsided result in the comparison is PassMark integer math, where the Core i9-14900 scores 175,010 against the Core 7 350's 33,734, a delta of 80.7% in favor of the desktop chip. Data compression shows a similar story: 550,271 versus 143,123, a 74% gap. Cinebench R23 multicore produces 31,070 points for the Core i9-14900 versus 8,030 for the Core 7 350, a 74.2% difference. Random string sorting also favors the Core i9-14900 heavily, with a score of 61,060 compared to 17,238, a 71.8% deficit for the mobile part.

The Core i9-14900 dominates memory-sensitive and encryption workloads as well. Data encryption shows 33,540 against 10,933, a 67.4% margin. Floating point math delivers 120,262 versus 42,809, a 64.4% gap. Extended instructions come in at 30,624 versus 12,045, a 60.7% difference. Cinebench R20 multicore shows 15,910 versus 5,373, a 66.2% gap, and the same 66.2% delta appears in Cinebench R20 singlecore, where the Core i9-14900 scores 2,245 against 758. Physics tests show 2,486 versus 1,173, a 52.8% advantage for the desktop part. Prime number finding produces 188 versus 107, a 43.1% gap.

The closest margins appear in single-threaded tests. PassMark single-thread scores 4,323 for the Core i9-14900 and 4,100 for the Core 7 350, a 5.2% difference. Cinebench R23 singlecore shows 2,212 versus 2,046, a 7.5% gap. Cinebench R15 singlecore produces 315 against 292, a 7.3% margin. These results indicate the Core 7 350's architecture is competitive on a per-thread basis, but the Core i9-14900 still holds the edge in every recorded test.

Architecture Differences

The two processors are built on fundamentally different designs. The Core i9-14900 uses Raptor Lake-R architecture on a 10 nm process, while the Core 7 350 uses Wildcat Lake on a 3 nm node. The Core i9-14900 is a desktop part with 24 cores and 32 threads, while the Core 7 350 is a mobile part with 6 cores and 6 threads. This core count difference explains the massive multicore deltas: the Core i9-14900 has four times the cores of the Core 7 350.

Cache configurations diverge sharply. The Core i9-14900 carries 36 MB of shared L3 cache, six times the 6 MB found on the Core 7 350. Per-core L1 and L2 allocations also differ: the Core i9-14900 has 80 KB of L1 and 2 MB of L2 per core, while the Core 7 350 has 192 KB of L1 and 2.5 MB of L2 per core. The mobile part actually has larger per-core caches, but the desktop chip's total cache pool is far larger due to its core count.

Memory support separates the two as well. The Core i9-14900 supports both DDR4 and DDR5 in a dual-channel configuration, while the Core 7 350 supports DDR5 and LPDDR5X over a single-channel bus. The Core 7 350 records 59.7 GB/s of memory bandwidth; the Core i9-14900 has no recorded bandwidth figure in the database. ECC memory is supported on the Core i9-14900 but not on the Core 7 350. PCIe connectivity also differs: the Core i9-14900 provides Gen 5 with 16 CPU lanes, while the Core 7 350 provides Gen 4 with 6 CPU lanes.

Clock speeds favor the desktop part. The Core i9-14900 boosts to 5.80 GHz with a 2.00 GHz base clock, while the Core 7 350 boosts to 4.80 GHz with a 1.50 GHz base clock. The Core i9-14900 has a 65 W TDP, compared to 15 W for the Core 7 350. The Core i9-14900 uses the Intel Socket 1700, while the Core 7 350 uses Intel BGA 1516, indicating the mobile part is soldered rather than socketed. Integrated graphics also differ: the Core i9-14900 uses UHD Graphics 770, while the Core 7 350 uses Intel Xe3 Graphics with 2 Xe cores.

Where Each One Wins

The Core i9-14900 wins every benchmark in the database, so the comparison is about degree rather than direction. The desktop chip's largest advantages come in heavily parallel workloads: integer math at 80.7% ahead, Cinebench R15 multicore at 74.5% ahead, Cinebench R23 multicore at 74.2% ahead, and data compression at 74% ahead. These workloads scale with core count and thread count, where the Core i9-14900's 24 cores and 32 threads overwhelm the Core 7 350's 6 cores and 6 threads.

The Core 7 350 is comparatively strongest in single-threaded tests. PassMark single-thread shows only a 5.2% gap, and Cinebench R15 and R23 singlecore show gaps of 7.3% and 7.5% respectively. The mobile part's 3 nm process and newer Wildcat Lake architecture narrow the per-thread performance difference, even though the Core i9-14900 still wins. The Core 7 350 also has a far lower 15 W TDP, making it suitable for thermally constrained mobile systems, whereas the Core i9-14900's 65 W TDP targets desktop builds.

The Core 7 350's larger per-core L1 and L2 caches suggest strong single-thread responsiveness, but benchmark results show the Core i9-14900 retains the single-thread crown. The Core i9-14900's 5.80 GHz boost clock, 1.00 GHz higher than the Core 7 350's 4.80 GHz, contributes to its single-thread lead. The data indicates the Core 7 350 is a capable mobile processor that trades multicore throughput for efficiency, while the Core i9-14900 is designed to maximize both single and multi-threaded performance.
