Intel Core 5 330 vs Intel Processor U300L Comparison

Head-to-Head Benchmarks

The Intel Core 5 330 and the Intel Processor U300L occupy very different positions in the database, and the gap is immediately visible in their percentile rankings. The Core 5 330 sits at the 72nd percentile of all CPUs, while the U300L lands at the 50th percentile. That 22-point percentile spread translates directly into the performance measurements recorded for the Core 5 330, which has a full suite of benchmark results; the U300L has no recorded benchmark scores in the database, meaning the comparison relies on the architectural and specification data rather than direct head-to-head run scores.

The Core 5 330 delivers a Cinebench R23 multi-core score of 13150 and a single-core score of 1856. In Cinebench R20, the multi-core result is 5523 and the single-core result is 779. The older Cinebench R15 test shows 1325 multi-core and 186 single-core. These scores place the Core 5 330 in direct competition with several familiar desktop parts: the Intel Core i3-14100 averages 18318 with a delta of 0.1 percent against the Core 5 330, the Intel Core 7 360 averages 18374 with a delta of -0.2 percent, the Intel Core i3-13100 averages 18380 with a delta of -0.2 percent, and the Intel Core 3 305 averages 18302 with a delta of 0.2 percent. The Core 5 330's average benchmark score of 18345 puts it within a fraction of a percent of all four rivals, indicating that its overall throughput is statistically indistinguishable from those parts in aggregate.

PassMark results for the Core 5 330 show a multi-thread score of 15471 and a single-thread score of 4088. Data compression reaches 145287, data encryption reaches 11076, and extended instructions score 12808. Floating point math hits 43885, integer math hits 33258, and the physics test records 1201. Random string sorting completes at 17771, and prime number finding scores 114. The U300L has no numerical scores to compare, so the database cannot produce a direct win count between the two chips.

Architecture Differences

The two processors come from different manufacturing generations and use different process nodes. The Intel Core 5 330 is built on a 3 nm process under the Wildcat Lake codename, while the Intel Processor U300L uses a 10 nm process under the Raptor Lake-PS codename with the Raptor Lake architecture. Both parts are manufactured by Intel, but the process gap is substantial: 3 nm versus 10 nm.

Core counts differ as well. The Core 5 330 has 6 cores and 6 threads, meaning no hyper-threading is in play. The U300L has 5 cores and 6 threads, which indicates that one of its cores supports an extra thread. Clock speeds favor the Core 5 330: its base clock is 1.50 GHz and its boost clock is 4.60 GHz, while the U300L runs at a 1.20 GHz base and a 4.40 GHz boost.

Cache layouts are notably different. The Core 5 330 uses 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The U300L lists 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 8 MB of shared L3 cache. So the Core 5 330 has a larger L1 allocation overall, while the U300L has a larger L3 pool.

Memory support separates the two as well. The Core 5 330 supports DDR5 and LPDDR5X over a single-channel memory bus with a recorded bandwidth of 59.7 GB/s. The U300L supports DDR4 and DDR5 over a dual-channel memory bus, with no bandwidth figure recorded in the database. Neither chip supports ECC memory.

PCIe connectivity differs: the Core 5 330 provides Gen 4 with 6 CPU lanes, while the U300L provides Gen 4 with 8 CPU lanes. Integrated graphics also diverge: the Core 5 330 uses Intel Xe3 Graphics with 2 Xe cores, while the U300L uses UHD Graphics with 48 execution units.

Sockets are different as well. The Core 5 330 uses Intel BGA 1516, while the U300L uses Intel Socket 1700. Both are mobile-segment parts, both are currently active in production, and neither has an unlocked multiplier. Release dates place the Core 5 330 at 2026-04-15 and the U300L at 2024-04-07.

Where Each One Wins

The Core 5 330 wins on compute density and single-thread capability based on the recorded data. Its 4.60 GHz boost clock is 0.20 GHz higher than the U300L's 4.40 GHz, and its 6 cores all run at that capability without relying on additional threads. The single-core Cinebench R23 score of 1856, the R20 single-core score of 779, and the PassMark single-thread score of 4088 establish a strong baseline for lightly threaded workloads. The 3 nm process node also points to higher efficiency per clock, although the database does not record a direct power draw comparison beyond the shared 15 W TDP.

The Core 5 330 also wins on memory bandwidth. Its recorded 59.7 GB/s is a concrete figure, and the use of LPDDR5X alongside DDR5 gives it access to lower-latency mobile memory configurations. The single-channel bus is a limitation, but the recorded bandwidth is still a defined number, whereas the U300L has no bandwidth figure in the database.

The U300L wins on platform flexibility. It supports both DDR4 and DDR5, which allows it to drop into systems with either memory generation. Its dual-channel memory bus is a structural advantage over the Core 5 330's single-channel bus, even without a recorded bandwidth number to quantify it. The U300L also offers more PCIe lanes at 8 versus 6, which matters for connecting additional Gen 4 devices. Its larger 8 MB shared L3 cache compared to the Core 5 330's 6 MB shared L3 cache gives it more on-chip data capacity for workloads that fit within that pool.

The U300L also wins on thread count per core. With 5 cores and 6 threads, it extracts one extra thread from its core configuration, which can help in mixed workloads that benefit from additional scheduling slots. The Core 5 330 matches thread count at 6 threads but requires 6 cores to do so.

The Verdict

The data supports a clear split. For mobile users who prioritize raw single-thread performance, higher boost clocks, and a modern 3 nm process, the Intel Core 5 330 is the stronger choice. Its complete benchmark record shows a processor performing at the 72nd percentile overall, with Cinebench R23 multi-core at 13150 and PassMark multi-thread at 15471. Its nearest rivals in the database, all within 0.2 percent of its average score, confirm that it sits in a competitive performance tier.

For users who need platform flexibility, the Intel Processor U300L is the more adaptable part. It supports DDR4 and DDR5 memory, uses a dual-channel memory bus, provides 8 PCIe Gen 4 lanes, and has a larger shared L3 cache. Its 50th percentile ranking places it in the middle of the database, and while it has no recorded benchmark scores, its architectural advantages in memory compatibility and lane count are documented facts.

The launch MSRP for the Core 5 330 is $309. The launch MSRP for the U300L is $107. Both parts use a 15 W TDP, both are mobile-segment processors, and both are actively in production, so neither is a legacy or end-of-life choice.

The Core 5 330 is the performance pick based on measured results. The U300L is the compatibility pick based on memory and connectivity features. Users with existing DDR4 platforms or a need for more PCIe lanes should favor the U300L; users who want the higher clock speeds and the full benchmark validation of the Core 5 330 should select that part.
