Intel Core 7 350 vs Intel Processor U300L Comparison

Head-to-Head Benchmarks

The Intel Core 7 350 and the Intel Processor U300L represent two distinct tiers within Intel's mobile lineup, and the benchmark data reflects a substantial performance gulf between them. The Core 7 350 holds complete dominance across every recorded workload, though direct head-to-head comparisons are complicated by the fact that the U300L has no recorded benchmark scores in the database. Instead, the analysis relies on the Core 7 350's absolute scores and its position relative to other processors.

The Core 7 350 delivers a Cinebench R23 multi-core score of 8030 and a single-core score of 2046. In Cinebench R20, it posts 5373 multi-core and 758 single-core. The older Cinebench R15 test shows 1220 multi-core and 292 single-core. These figures place the chip at the 71st percentile among all CPUs tracked in the database, with an average benchmark score of 17779.

For context, the Core 7 350's nearest rivals in the database include the Intel Core 5 221TE with an average score of 17860, which trails the Core 7 350 by 0.5 percent. The AMD EPYC 9374F scores 17693, putting it 0.5 percent behind. The AMD Ryzen 5 3600XT averages 17891, which is 0.6 percent ahead of the Core 7 350, and the Intel Core 5 120U scores 17898, 0.7 percent ahead. This clustering indicates that the Core 7 350 sits in a tightly contested performance band where small margins separate competitors.

The U300L, by contrast, holds a 50th percentile ranking and an average benchmark score of zero due to the absence of recorded measurements. With no benchmark data available, the database cannot quantify its performance relative to the Core 7 350 or any other processor. What can be stated is that the Core 7 350's scores across all tests represent the only measurable performance data in this comparison.

PassMark workloads further characterize the Core 7 350's capabilities. It scores 143123 in data compression, 10933 in data encryption, and 12045 in extended instructions. Integer math reaches 33734, floating point math hits 42809, and the find prime numbers test yields 107. Multithread performance registers 15170, physics scores 1173, and random string sorting achieves 17238. Single-thread performance is recorded at 4100 in both PassMark single-thread tests.

Where Each One Wins

The Core 7 350 wins in every measurable category because it is the only processor in this pairing with recorded benchmark results. Its multi-core Cinebench scores, particularly the R23 result of 8030, indicate strong sustained throughput for threaded workloads such as rendering, video encoding, and scientific computation. The single-core score of 2046 in R23 suggests solid responsiveness for lightly threaded tasks including office applications, web browsing, and legacy software.

The PassMark results break down performance by workload type. Data compression at 143123 points to efficient handling of archive operations and file transfer workloads. Encryption at 10933 reflects cryptographic throughput for secure communications and disk encryption. Floating point math at 42809 supports simulation and modeling tasks, while integer math at 33734 covers general-purpose computing. The physics score of 1173 provides a glimpse into gaming-related physics calculations, though this is a mobile chip with integrated graphics.

The U300L's wins cannot be quantified from the database because no benchmark scores exist for it. Its 50th percentile ranking suggests it occupies the median position among all tracked CPUs, but without concrete test results, any specific workload advantage remains undocumented. The data can only state that the U300L has no recorded wins in the database.

For use-case planning, the Core 7 350's profile indicates suitability for mobile workstations and high-end ultrathin laptops where both multi-threaded and single-threaded performance matter. The U300L, given its lower core count and older architecture, would logically serve less demanding roles, but the database lacks the measurements to confirm this.

Architecture Differences

The 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 foundry. The U300L uses the Raptor Lake architecture with the Raptor Lake-PS codename and belongs to the Intel Processor (Raptor Lake) generation. Its process node is 10 nm, also fabricated by Intel.

Core counts differ significantly. The Core 7 350 has 6 cores and 6 threads, meaning no hyperthreading is present. The U300L has 5 cores and 6 threads, indicating that one core supports an additional thread. This arrangement gives the U300L a thread count equal to its core count plus one, while the Core 7 350 has a one-to-one core-to-thread ratio.

Cache hierarchies diverge substantially. The Core 7 350 features 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 6 MB of shared L3 cache. The U300L has 80 KB of L1 per core, 1.25 MB of L2 per core, and 8 MB of shared L3 cache. While the U300L has more total L3, the Core 7 350 has larger per-core L1 and L2 allocations.

The integrated graphics differ as well. The Core 7 350 uses Intel Xe3 Graphics with 2 Xe execution units. The U300L uses UHD Graphics with 48 execution units. Despite the larger execution unit count on the U300L, the architecture generation difference means direct capability comparison requires real-world testing, which the database does not provide for the U300L.

Process node differences carry implications for power efficiency and transistor density. The 3 nm node on the Core 7 350 represents a more advanced manufacturing process than the 10 nm node on the U300L, which typically allows higher performance at equivalent power or lower power at equivalent performance. However, the database does not include measured power consumption figures beyond the 15 watt TDP shared by both processors.

Specification Differences

The two processors differ across several specification fields while sharing some common traits. Both have a 15 watt TDP and both are classified as mobile market segment parts with active production status. Neither has an unlocked multiplier.

Clock speeds diverge. The Core 7 350 has a base clock of 1.50 GHz and a boost clock of 4.80 GHz. The U300L has a base clock of 1.20 GHz and a boost clock of 4.40 GHz. The Core 7 350 thus has both a higher base frequency and a higher boost frequency.

Sockets differ. The Core 7 350 uses Intel BGA 1516, while the U300L uses Intel Socket 1700. This means the two processors are not socket-compatible and cannot be swapped between the same motherboard designs.

Memory support varies. The Core 7 350 supports DDR5 and LPDDR5X memory with a single-channel memory bus and a memory bandwidth of 59.7 GB/s. The U300L supports DDR4 and DDR5 memory with a dual-channel memory bus, though its memory bandwidth is not recorded in the database. Neither processor supports ECC memory.

PCIe connectivity differs. The Core 7 350 provides PCIe Gen 4 with 6 lanes (CPU only). The U300L provides PCIe Gen 4 with 8 lanes (CPU only). The U300L offers two additional PCIe lanes for peripheral connectivity.

Release dates and launch MSRP values differ. The Core 7 350 has a launch MSRP of $469 and released on 2026-04-15. The U300L has a launch MSRP of $107 and released on 2024-04-07. The U300L accordingly launched earlier and at a substantially lower launch MSRP. Part numbers also differ: the Core 7 350 carries part number SAE3F, while the U300L carries SRPEKSRPEM.
