Intel Core 5 320 vs Intel Processor U303L Comparison

Head-to-Head Benchmarks

The Core 5 320 has a recorded benchmark suite, while the U303L has no recorded scores in the database. This makes a direct score-to-score comparison impossible. However, the Core 5 320's individual results can be positioned against its nearest rivals to establish its performance class.

In Cinebench R23, the Core 5 320 scores 6197 multi-core and 1926 single-core. The single-core result is particularly strong, ranking in the 72nd percentile of all CPUs. The multi-core result keeps it competitive with older desktop parts, as its average benchmark score of 18023 is within 0.2% of the AMD Ryzen 5 1600 (17994) and within 0.7% of the Intel Core 5 120U (17898). It trails the Intel Core i5-1334U by 0.7% (18154).

PassMark results reinforce the single-thread advantage. The Core 5 320 records 4045 in PassMark single-thread tests, with a multi-thread score of 15450. Integer math reaches 32323, floating-point math reaches 42440, and extended instructions hit 13262. Data compression scores 148779, while encryption scores 10984. Prime number finding scores 110, and random string sorting reaches 18038. Physics processing scores 1221.

The U303L has no benchmark entries at all. Its percentile rank of 50 places it at the median of all recorded CPUs, but the database contains no test scores to confirm what that rank represents. The Core 5 320's 72nd percentile rank is supported by 17 recorded benchmark results. The data therefore confirms the Core 5 320 as the measured performer, while the U303L remains unverified in the database.

Architecture Differences

The two processors come from entirely different design generations. The Core 5 320 uses the Wildcat Lake architecture on a 3 nm process node, built by Intel. The U303L uses the Raptor Lake architecture on a 10 nm process node, also Intel-built. The Core 5 320 belongs to the Core 5 (Wildcat Lake) generation, while the U303L belongs to the Intel Processor (Raptor Lake) generation.

Core counts differ: the Core 5 320 has 6 cores and 6 threads, while the U303L has 5 cores and 6 threads. Thread counts match, but the Core 5 320 has one additional physical core. The U303L's thread count exceeds its core count, indicating Hyper-Threading support, while the Core 5 320 matches cores to threads.

Clock speeds differ substantially. The Core 5 320 runs at 1.50 GHz base and boosts to 4.60 GHz. The U303L runs at 1.20 GHz base and boosts to only 2.60 GHz. That is a 2.0 GHz difference in maximum boost clocks, a major factor in the Core 5 320's measured single-thread dominance.

Cache configurations are structurally different. The Core 5 320 has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The U303L has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 12 MB of shared L3 cache. The U303L offers twice the total L3 capacity, but the Core 5 320's cache is organized at the processor level rather than per core.

Memory support differs. The Core 5 320 supports DDR5 and LPDDR5X memory over a single-channel bus with 59.7 GB/s of bandwidth. The U303L supports DDR4 and DDR5 over a dual-channel bus, with no bandwidth figure recorded. The Core 5 320 has a recorded bandwidth advantage, while the U303L's dual-channel configuration suggests different memory characteristics without a measured number.

PCIe connectivity differs in lane count. The Core 5 320 provides Gen 4 with 6 CPU-only lanes. The U303L provides Gen 4 with 8 CPU-only lanes. Integrated graphics also differ: the Core 5 320 uses Intel Xe3 Graphics with 2 Xe cores, while the U303L uses UHD Graphics with 96 execution units.

Sockets are incompatible. The Core 5 320 uses Intel BGA 1516, while the U303L uses Intel Socket 1700. The Core 5 320 was released on 2026-04-15, and the U303L on 2024-04-07.

The Verdict

The recorded data favors the Core 5 320 in every measurable category. It has a 72nd percentile rank versus the U303L's 50th percentile. It has 17 benchmark scores in the database; the U303L has zero. The Core 5 320's boost clock reaches 4.60 GHz versus the U303L's 2.60 GHz. Its process node is 3 nm versus 10 nm. Its base clock is 1.50 GHz versus 1.20 GHz. It has 6 cores versus 5.

The U303L holds advantages in L3 cache capacity (12 MB versus 6 MB), PCIe lanes (8 versus 6), and memory channel width (dual-channel versus single-channel). It also supports DDR4 in addition to DDR5, while the Core 5 320 supports DDR5 and LPDDR5X. None of these advantages appear in the benchmark data, because no benchmark data exists for the U303L.

The launch MSRP of the Core 5 320 is $340. The launch MSRP of the U303L is $285. The database does not record performance scores for the U303L, so no performance-per-dollar analysis is possible.

For users requiring verified performance, the Core 5 320 is the only option with recorded data. For users requiring dual-channel memory support or larger L3 cache, the U303L offers those features, but their performance impact cannot be quantified from the database.

Where Each One Wins

The Core 5 320 wins in measured performance categories. Its 4.60 GHz boost clock and 1.50 GHz base clock are both higher than the U303L's 2.60 GHz and 1.20 GHz. Its 3 nm process node is three generations ahead of the U303L's 10 nm node. Its 6 cores exceed the U303L's 5 cores. Its 59.7 GB/s memory bandwidth is recorded, while the U303L has no bandwidth figure. Its 72nd percentile rank is backed by actual test data.

The Core 5 320's benchmark results indicate strength in single-thread workloads. The Cinebench R23 single-core score of 1926 and PassMark single-thread score of 4045 both sit above the 72nd percentile boundary. The R23 multi-core score of 6197 and Cinebench R20 multi-core score of 5462 confirm that multi-threaded performance is also competitive, landing within 0.7% of the Intel Core 5 120U and 0.2% of the AMD Ryzen 5 1600.

The U303L wins in memory channel width, offering dual-channel support against the Core 5 320's single-channel bus. It also offers a larger shared L3 cache at 12 MB versus 6 MB, more CPU-only PCIe lanes at 8 versus 6, and DDR4 compatibility alongside DDR5. Its 96EU UHD Graphics may provide different integrated graphics characteristics than the Core 5 320's Xe3 Graphics with 2 Xe cores, though no graphics benchmarks are recorded for either part.

The Core 5 320 is the appropriate choice for workloads where single-thread speed is the priority. The recorded single-core scores are strong relative to its own multi-core results, and the 4.60 GHz boost clock gives it a clear frequency advantage. The U303L is the appropriate choice for configurations requiring dual-channel memory or DDR4 support, or for systems built around Intel Socket 1700. The U303L's larger L3 cache may benefit cache-sensitive workloads, but the database contains no scores to confirm this.

The U303L's lower launch MSRP of $285 versus the Core 5 320's $340 may factor into purchasing decisions, but without benchmark data for the U303L, the database cannot determine whether that price difference corresponds to a performance difference. The Core 5 320 remains the only one of the two with verified performance records.
