Intel Core 7 150U vs Intel Core 7 350 Comparison

Head-to-Head Benchmarks

The Intel Core 7 350 and Intel Core 7 150U present a fascinating split in the benchmark data. The Core 7 350 wins 12 of the 17 recorded head-to-head tests, while the Core 7 150U takes 5. But the margin and nature of those wins tell a more nuanced story than the raw win count suggests.

The most lopsided result in either direction belongs to the Core 7 350 in the PassMark prime number search test. It scores 107 against the 150U's 58, a gap of 84.5 percent. That is an enormous advantage in a single-threaded integer workload. The extended instructions test is nearly as one-sided, with the Core 7 350 posting 12045 to the 150U's 8748, a 37.7 percent lead. Floating point math also favors the Core 7 350 heavily, 42809 versus 34405, a 24.4 percent edge. These are not marginal differences; they point to a fundamental advantage in per-core execution efficiency.

Single-threaded performance is consistently in the Core 7 350's corner. In Cinebench R15 single-core, it scores 292 against 254, a 15 percent advantage. The R20 single-core test shows a narrower 2.4 percent lead, 758 to 740. In R23 single-core, the Core 7 350 extends its lead to 9.1 percent, scoring 2046 versus 1875.5. The PassMark single-thread test confirms the pattern with a 16.9 percent margin, 4100 to 3508. The data shows a clear pattern: the Core 7 350 is the stronger chip for lightly threaded workloads.

The Core 7 150U fights back in multi-threaded scenarios, but not universally. In Cinebench R15 multi-core, the 150U wins decisively with 1505.5 against 1220, a 19 percent lead. The R23 multi-core test also goes to the 150U, 8883 versus 8030, a 9.6 percent margin. However, the R20 multi-core result flips the other way, with the Core 7 350 winning 5373 to 5248, a 2.4 percent edge. The PassMark multithread test also goes to the Core 7 350, 15170 against 14700, a 3.2 percent lead. The inconsistency suggests the 150U's advantage depends heavily on the specific workload and how well it scales across its additional cores.

Integer math is the 150U's strongest individual result. It scores 51057 in the PassMark integer math test, compared to 33734 for the Core 7 350, a massive 33.9 percent advantage. This is the single largest win for the 150U in the entire dataset. Data compression also favors the 150U, 158622 versus 143123, a 9.8 percent lead. Random string sorting goes to the 150U by a narrower 5.6 percent margin, 18269 to 17238.

The Core 7 350 counters with wins in data encryption, 10933 versus 10025, a 9.1 percent edge, and in the PassMark physics test, 1173 versus 1012, a 15.9 percent margin. These results reinforce the picture of the Core 7 350 as a chip that excels when instructions can be executed efficiently on fewer, faster cores.

Looking at overall averages, the two chips are far closer than the win count suggests. The Core 7 350 has an average benchmark score of 17779, while the Core 7 150U sits at 17395. The nearest rivals data places the Core 7 350 within 0.5 percent of the AMD EPYC 9374F and within 0.7 percent of the Intel Core 5 120U. The Core 7 150U is within 0.4 percent of the AMD Ryzen 5 4500 and AMD Ryzen 3 210. Both chips land at the 71st percentile among all CPUs in the database, meaning they occupy essentially the same tier of overall performance.

The Verdict

The benchmark results indicate two different design philosophies serving two different workload profiles. The Intel Core 7 350 is the pick for users whose applications depend on single-threaded speed and instruction efficiency. Its 84.5 percent lead in prime number search, 37.7 percent lead in extended instructions, and 24.4 percent lead in floating point math are decisive. Any workload that is latency-bound or poorly threaded will run noticeably better on the Core 7 350.

The Intel Core 7 150U is the pick for integer-heavy and compression-heavy workloads that can utilize its additional cores. The 33.9 percent lead in integer math and 9.8 percent lead in data compression are significant. For content creation tasks that scale well across cores, the 150U holds an edge in several Cinebench runs, particularly the 19 percent margin in R15 multi-core.

However, the multi-threaded picture is not clean. The Core 7 350 actually wins the R20 multi-core test and the PassMark multithread test. So the 150U is not universally better in multi-threaded work; its advantage is workload-specific. Users who need maximum performance in broadly threaded rendering should look at the R23 result, where the 150U leads by 9.6 percent. Users who run a mix of single-threaded and multi-threaded tasks will likely find the Core 7 350 the more consistent performer, given its 12 wins across the full test suite.

Both chips sit at the 71st percentile, so neither is a class leader. The choice comes down to workload mix. Single-threaded and floating-point heavy: Core 7 350. Integer and compression heavy: Core 7 150U. The data does not support a blanket recommendation for either part.

Architecture Differences

The two processors come from completely different design lineages. The Intel Core 7 350 uses the Wildcat Lake codename and belongs to the Core 5 (Wildcat Lake) generation. It is built on a 3 nm process node at Intel's own foundry. The Intel Core 7 150U uses the Raptor Lake architecture with the Raptor Lake-U codename and is manufactured on a 10 nm process, also at Intel. The process node difference is substantial: 3 nm versus 10 nm is a generational leap in manufacturing technology.

The core counts reflect this architectural divergence. The Core 7 350 has 6 cores and 6 threads, meaning no hyper-threading. The Core 7 150U has 10 cores and 12 threads, indicating a hybrid design with performance and efficiency cores. The 150U's thread count of 12 versus 10 cores suggests two of its cores support hyper-threading.

Cache configurations differ significantly. The Core 7 350 has 192 KB of L1 cache per core and 2.5 MB of L2 cache per core, with a shared 6 MB L3 cache. The Core 7 150U has 80 KB of L1 per core and 1.25 MB of L2 per core, with a larger shared 12 MB L3 cache. The 150U's L3 advantage is double, but the Core 7 350's per-core L1 and L2 allocations are larger, which contributes to its single-threaded efficiency.

Memory support also differs. The Core 7 350 supports DDR5 and LPDDR5X memory, while the Core 7 150U supports DDR4 and DDR5. The Core 7 350 uses a single-channel memory bus with 59.7 GB/s of bandwidth. The Core 7 150U uses a dual-channel memory bus, though its bandwidth figure is not recorded in the database. The 150U's dual-channel configuration is typically advantageous for memory bandwidth, but the Core 7 350's support for LPDDR5X could offset some of that in low-power mobile designs.

PCIe connectivity differs as well. The Core 7 350 provides Gen 4 with 6 lanes (CPU only), while the Core 7 150U provides Gen 4 with 8 lanes (CPU only). The 150U offers two additional PCIe lanes for peripheral connectivity.

Integrated graphics are another point of divergence. The Core 7 350 features Intel Xe3 Graphics with 2 Xe cores. The Core 7 150U features Iris Xe Graphics with 96 execution units. The 150U's graphics solution has a substantially higher execution unit count, which typically translates to better integrated graphics performance, though no graphics benchmarks are recorded in the database to confirm this.

Neither chip supports ECC memory, and neither has an unlocked multiplier. The Core 7 350 has a launch MSRP of $469; no launch MSRP is recorded for the Core 7 150U.

Specification Differences

The core and thread counts differ as noted: 6 cores and 6 threads for the Core 7 350, versus 10 cores and 12 threads for the Core 7 150U. The 150U offers 4 additional cores and 6 additional threads.

Clock speeds favor the 150U on paper. The Core 7 350 has a base clock of 1.50 GHz and a boost clock of 4.80 GHz. The Core 7 150U has a base clock of 1.80 GHz and a boost clock of 5.40 GHz. The 150U is 0.30 GHz higher at base and 0.60 GHz higher at boost. Despite this, the Core 7 350 wins the majority of single-threaded benchmarks, which underscores the architectural efficiency advantage of the newer 3 nm design.

Both parts have a TDP of 15 watts, placing them in the same power envelope for mobile designs. Both use Intel BGA sockets, but they are different sockets: the Core 7 350 uses BGA 1516, while the Core 7 150U uses BGA 1744. These are not interchangeable, meaning the two chips cannot be swapped in the same motherboard.

The process node difference is stark: 3 nm for the Core 7 350 versus 10 nm for the Core 7 150U. The release dates reflect the generational gap. The Core 7 150U was released on January 7, 2024. The Core 7 350 was released on April 15, 2026, more than two years later.

The part numbers differ: SAE3F for the Core 7 350 and SRMYP for the Core 7 150U. Both chips are currently marked as Active in production status, and both target the mobile market segment.
