Intel Core 7 350 vs Intel Core i5-1334U Comparison

Head-to-Head Benchmarks

The head-to-head data shows a clear split between the two processors, with the Intel Core 7 350 winning 13 of the 17 recorded comparisons, while the Intel Core i5-1334U takes 4 wins. The victories for each side are concentrated in different workloads, and the margins are substantial in both directions.

The Core i5-1334U's largest win comes in PassMark integer math, where it scores 50,374 against the Core 7 350's 33,734, a 49.3% advantage. This is the single biggest delta in the entire comparison, and it suggests the i5's hybrid core layout with 10 cores and 12 threads handles integer-heavy parallel work far more effectively. The i5 also wins in Cinebench R23 multi-core, scoring 8,641 versus 8,030, a 7.6% lead, and in Cinebench R15 multi-core with 1,569 against 1,220, a 28.6% gap. Data compression also favors the i5, with 150,568 points versus 143,123, a 5.2% edge.

The Core 7 350, by contrast, dominates single-threaded and lightly threaded tests. Its most decisive win is in PassMark find prime numbers, where it scores 107 versus just 39, a 63.6% advantage. That result is striking: the Core 7 350 is nearly three times as fast in this specific workload. Extended instructions also lean heavily toward the Core 7 350, with 12,045 points against 8,563, a 28.9% margin. Physics simulation shows a 38.4% lead for the Core 7 350, scoring 1,173 versus 722.

In Cinebench R20, the Core 7 350 wins both multi-core and single-core. The multi-core result is notable: 5,373 versus 4,638, a 13.7% advantage, even though the Core 7 350 has only 6 cores and 6 threads compared to the i5's 10 cores and 12 threads. Single-core R20 shows 758 versus 654, also 13.7%. Cinebench R23 single-core follows the same pattern, with the Core 7 350 at 2,046 versus 1,727, a 15.6% lead. PassMark single-thread shows 4,100 versus 3,345, an 18.4% edge.

The remaining wins for the Core 7 350 are narrower but consistent. Data encryption goes to the Core 7 350 at 10,933 versus 9,377, a 14.2% margin. PassMark multithread favors the Core 7 350 at 15,170 versus 13,410, an 11.6% difference. Random string sorting is close, with the Core 7 350 ahead 17,238 versus 16,933, just 1.8%. Cinebench R15 single-core shows 292 versus 241, a 17.5% gap.

The overall average benchmark scores are close: the Core i5-1334U averages 18,154, while the Core 7 350 averages 17,779. The i5 lands at the 72nd percentile of all CPUs, and the Core 7 350 sits at the 71st. The i5's nearest rivals include the AMD Ryzen 3 8300G, AMD Ryzen 7 5700U, Intel Core i7-1365U, and Intel Core i7-9700, all within 0.1% of its average score. The Core 7 350's nearest rivals are the Intel Core 5 221TE, AMD EPYC 9374F, AMD Ryzen 5 3600XT, and Intel Core 5 120U, with deltas ranging from 0.5% to 0.7%.

Architecture Differences

The two chips come from completely different design philosophies and manufacturing generations. The Intel Core i5-1334U is built on Raptor Lake architecture with a 10 nm process node at Intel's foundry, using the Raptor Lake-U codename. It belongs to the Core i5 generation. The Intel Core 7 350 uses the Wildcat Lake codename, belongs to the Core 5 generation, and is fabricated on a 3 nm process node, also at Intel's foundry. The process node difference is a full 7 nm, which explains some of the efficiency and clock advantages the Core 7 350 shows.

Core counts differ sharply. The i5-1334U has 10 cores and 12 threads, implying a hybrid arrangement with performance and efficiency cores. The Core 7 350 has 6 cores and 6 threads, with no hyper-threading indicated. Despite having fewer cores, the Core 7 350 reaches a higher boost clock: 4.80 GHz versus 4.60 GHz. Its base clock is also higher at 1.50 GHz versus 1.30 GHz.

Cache layouts are substantially different. The i5-1334U uses 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The Core 7 350 uses 192 KB of L1 per core, 2.5 MB of L2 per core, but only 6 MB of shared L3. So the Core 7 350 has larger per-core caches but half the total L3. This explains why the Core 7 350 excels in single-threaded and cache-sensitive workloads while the i5's larger shared L3 helps in multi-threaded scenarios.

Memory support diverges as well. The i5-1334U supports DDR4 and DDR5 over a dual-channel memory bus. The Core 7 350 supports DDR5 and LPDDR5X, but on a single-channel bus, with a recorded memory bandwidth of 59.7 GB/s. The i5's memory bus width is wider, but the Core 7 350 supports faster memory types.

PCI Express lanes also differ. The i5-1334U provides Gen 4 with 8 lanes from the CPU. The Core 7 350 provides Gen 4 with 6 lanes. Integrated graphics are different generations: the i5 uses Iris Xe Graphics with 80 execution units, while the Core 7 350 uses Intel Xe3 Graphics with 2 Xe cores.

Sockets are incompatible: the i5-1334U uses Intel BGA 1744, and the Core 7 350 uses Intel BGA 1516. Both have a 15 W TDP and are active in production. Neither has an unlocked multiplier. The i5-1334U was released on 2023-01-03, while the Core 7 350 was released on 2026-04-15, a gap of over three years. The launch MSRP for the i5-1334U is $340, and for the Core 7 350 it is $469.

The Verdict

The data points to a clear specialization split. The Intel Core 7 350 is the better choice for single-threaded performance, lightly threaded workloads, and tasks that benefit from high clock speeds and larger per-core caches. Its 4.80 GHz boost clock, 3 nm process, and larger L1 and L2 caches drive wins across Cinebench single-core tests, PassMark single-thread, physics, floating-point math, extended instructions, find prime numbers, and data encryption. For users running everyday applications, productivity software, or any workload that relies heavily on single-core responsiveness, the Core 7 350 is the stronger part.

The Intel Core i5-1334U is the pick for multi-threaded integer work and certain parallel rendering tasks. It wins Cinebench R15 and R23 multi-core, integer math, and data compression. Its 10 cores and 12 threads, combined with 12 MB of shared L3, give it an edge in workloads that scale across many threads and benefit from a larger shared cache. The i5's 49.3% lead in integer math is substantial, and its 28.6% win in Cinebench R15 multi-core shows real parallel strength.

The overall average benchmark scores are nearly identical, with the i5 at 18,154 and the Core 7 350 at 17,779, and their percentiles are essentially tied at 72 and 71. Neither chip is a clear overall winner. The deciding factor should be workload. If the target applications are single-threaded or latency-sensitive, the Core 7 350's architecture delivers superior results. If the workload is heavily multi-threaded integer processing, the i5-1334U's core count and cache arrangement win out. The Core 7 350 also offers newer memory support with LPDDR5X and a smaller process node, while the i5 retains dual-channel memory and a wider PCIe configuration. Choose based on the specific benchmark profile that matches the intended use.
